Description

  The present invention relates to a wireless device, a wireless LAN router device using the wireless device, and an antenna direction setting method for the wireless device, and more particularly, a fixed wireless device, a wireless LAN router device using the wireless device, The present invention relates to an antenna direction setting method in a wireless device.

  There is known a wireless device that can select an arbitrary installation form from among a plurality of installation forms by using a stand or the like.

  FIG. 1 is a diagram when the wireless device 10 that can be stationary and wall-mounted by using the stand 17 is stationary. FIG. 1A is an overhead view of the wireless device 10. FIG. 1B is a side view of the wireless device 10.

  FIG. 2 is a diagram of a case where the wireless device 10 that can be stationary and wall-mounted by using the stand 17 is wall-mounted. FIG. 2A is an overhead view of the wireless device 10. FIG. 2B is a side view of the wireless device 10.

  As described above, in the wireless device 10 in which a plurality of installable forms are prepared, the direction of the antenna 111 may be optimized in accordance with each installable form. Here, unless a setting method in the direction of the antenna 111 is particularly specified, a general user who is not familiar with wireless communication tends to stand the antenna 111 vertically regardless of whether it is stationary or wall-mounted.

  However, when the antenna 111 stands upright, the characteristics of the antenna 111 may deteriorate. In particular, when the wireless device 10 is wall-mounted as shown in FIG. 2, the characteristics of the antenna 111 may be greatly deteriorated depending on the material of the wall. It should be noted that there is no particular problem when the wireless device 10 is deferred as shown in FIG.

  Furthermore, even a general user who is not familiar with wireless communication may not be able to change the direction of the antenna 111 even if the characteristics of the antenna 111 are deteriorated, and may continue to use it as it is.

  Among wireless devices, the wireless LAN router device is often used in a fixed state once installed. Moreover, since the receiving party is often a mobile terminal, it is not meaningful to install the wireless LAN router device in an optimal form while checking the receiving sensitivity at the communicating party. Therefore, especially in the wireless LAN router apparatus, it is important to optimize the antenna characteristics in accordance with the installation form.

In relation to the above, Patent Document 1 (Japanese Patent Laid-Open No. 2000-174526) discloses a description relating to a mobile phone.
The mobile phone described in Patent Document 1 has an antenna for receiving radio waves protruding from the phone body. This cellular phone is characterized in that the antenna can be changed in the direction of the antenna with respect to the phone body.

Patent Document 2 (Japanese Patent Laid-Open No. 2001-057015) discloses a description relating to a disk device.
The disk device described in Patent Document 2 includes a disk rotating unit, a signal conversion head, and a head moving unit. Here, the disk rotating means has a spindle and is for rotating the recording medium disk around the spindle. The signal conversion head is used for writing and / or reading information on the disk. The head moving means is for moving the signal conversion head in the radial direction of the disk. This disk device is characterized by comprising direction signal generating means and control means. Here, the direction signal generating means generates a direction signal indicating the relationship between the direction in which the spindle extends and the vertical direction or the relationship between the moving direction of the signal conversion head and the vertical direction. The control means controls the disk rotating means or the head moving means so as to match the direction indicated by the direction signal in response to the direction signal.

Patent Document 3 (Act No. 07-013272) discloses a description relating to a portable electronic device.
The portable electronic device described in Patent Literature 3 includes a main body case and an upper case. Here, the main body case houses the keyboard. The upper case houses a display body, is rotatably connected to the main body case, and serves as a lid portion of the main body case. The portable electronic device includes a lock unit and a lock release unit. Here, the lock means senses the vertically placed state of the portable electronic device and locks the upper case so that it does not open when the upper case is closed. The lock release means detects the state in which the portable electronic device is placed horizontally and releases the lock of the upper case.

Patent Document 4 (Japanese Patent Application Laid-Open No. 2004-173235) discloses a description relating to an antenna device.
The antenna device described in Patent Literature 4 includes a bottom cover, an antenna case, an antenna base, and an angle adjustment mechanism. Here, the bottom cover accommodates an antenna element having directivity in the zenith direction, and the antenna element is placed thereon. The antenna case has a top cover that covers the antenna element. The antenna base is fixed to an arbitrary installation surface. The angle adjustment mechanism connects the antenna case and the antenna base so that the relative angle between the antenna case and the antenna base can be adjusted.

  The antenna device described in Patent Document 4 changes the direction of its own antenna after confirming the reception strength level of the communication partner. However, the communication partner of the wireless device 10 is not necessarily one. When performing wireless communication with a plurality of partners, it is not realistic to change the direction of the antenna each time the communication partner changes.

  Even if the wireless device 10 has only one communication partner, the reception strength level of the communication partner is unknown until the wireless device 10 detects the communication partner. Therefore, the direction of the antenna cannot be optimized until communication is started. When the wireless device 10 is used with the antenna characteristics deteriorated, the level of radio waves radiated from the radio device 10 may be weak, and radio waves may not reach the communication partner and wireless communication may not be possible.

Further, Patent Document 5 (Act No. 3102240) discloses a description relating to a rotational fixed position structure of an antenna and a fixed base.
The rotation fixed position structure of the antenna and the fixed base described in Patent Document 5 is characterized by the following. That is, this rotation home position structure is provided with a fixed base. The fixed base can stand firmly on a tabletop or other fixed object. The rotational home position structure includes a protrusion. The protrusion protrudes from the fixed base. The cross section of the protrusion appears in a U shape. One side of the protrusion appears on the open side. The remaining three sides are connected to each other to form a storage chamber. Corresponding pivot holes and arcuate grooves are provided on both corresponding inner side walls of the projection. This rotational home position structure includes an antenna body. The antenna body appears in the shape of a long plate and can fit into the storage chamber of the protrusion. A pivot and a fixed position protrusion are provided on both corresponding sides of one end of the antenna body. The pivot and the fixed position projection can be pivoted in the pivot hole and the arcuate groove on the corresponding inner side walls of the projection, so that the antenna body has the pivot as the rotation axis. The antenna body can be adjusted and rotated at an arbitrary angle from the open side of the protrusion, and at the same time, the antenna body can be moved and fixed in a circular arc groove through the fixed position protrusion.

  An object of the present invention is to provide a wireless device, a wireless LAN router device, and an antenna direction setting method that can easily optimize the antenna direction according to each of a plurality of installable forms.

  The wireless device of the present invention has a plurality of installable forms. The wireless device includes an installation form detection unit, an antenna unit, an antenna direction setting unit, and a control unit. Here, the installation form detection unit detects the installation form of the wireless device. The antenna unit has different characteristics depending on the direction. The antenna direction setting unit is for setting the direction of the antenna unit. A control part is for optimizing the direction of an antenna part according to the detected installation form. The control unit includes a table that stores information related to the optimum direction of the antenna unit corresponding to each of the plurality of installable forms.

  According to the antenna direction setting method of the present invention, (a) a step of detecting an installation form of a wireless device having a plurality of installable forms, and (b) an installation form of the wireless device detected in step (a), Setting the antenna unit of the wireless device in an optimum direction. Here, step (b) includes a step (b-1) of obtaining information related to the optimum direction of the antenna unit corresponding to each of the plurality of installable forms from the table of the wireless device.

  According to the present invention, the installation mode of the wireless device or the wireless LAN router device is detected, and the direction of the antenna is set based on the detection result. Note that the wireless device or the wireless LAN router device incorporates information related to the optimum antenna direction in each of the plurality of installable forms in advance. That is, the antenna direction can be optimized only by installing a wireless device or a wireless LAN router.

  The best mode for carrying out a wireless device, a wireless LAN router device, and an antenna direction setting method according to the present invention will be described below with reference to the accompanying drawings.

(First embodiment)
The external shape of the wireless device 10 according to the first embodiment of the present invention is the same as that of the related-art wireless device 10 described above, but will be described again.

  FIG. 1 is a schematic view of a wireless device 10 according to the first embodiment of the present invention. The wireless device 10 can be installed in a stationary state by using the stand 17. FIG. 1A is an overhead view when the wireless device 10 is installed in a stationary state. FIG.1 (b) is a side view at the time of installing this radio | wireless apparatus 10 in a stationary state.

  FIG. 2 is an overview of the wireless device 10 according to the first embodiment of the present invention. The wireless device 10 can also be installed in a wall-mounted state using the stand 17. FIG. 2A is an overhead view when the wireless device 10 is installed in a wall-mounted state. FIG. 2B is a side view when the wireless device 10 is installed in a wall-mounted state.

  The wireless device 10 according to the first embodiment of the present invention includes an antenna 111 as an antenna unit and a stand detection unit 141 as an installation form detection unit. The stand detection unit 141 has a plurality of stand connection units for connecting the stand 17. Different stand connection portions are used depending on the installation form of the wireless device 10.

  In FIG. 1, the stand 17 is connected to the stand connection portion at the bottom of the radio device 10, so that the radio device 10 can be stationary.

  In FIG. 2, the stand 17 is connected to the stand connection portion on the back of the radio device 10, so that the radio device 10 can be wall-mounted.

  At this time, the stand 17 may be the same for the stationary case or the wall hanging type, or may be different.

  FIG. 3 is a schematic circuit diagram of the wireless device 10 according to the first embodiment of the present invention. The wireless device 10 includes a stand detection unit 141, a control unit 13, an antenna direction setting unit 12, and a wireless circuit unit 15.

  The stand detection unit 141 is connected to the control unit 13. The control unit 13 is connected to the antenna direction setting unit 12. The antenna direction setting unit 12 is connected to the antenna 111. The radio circuit unit 15 is connected to the antenna 111 via the antenna direction setting unit 12. However, the radio circuit unit 15 may be directly connected to the antenna 111.

  FIG. 4 is a flowchart for explaining an antenna direction setting method according to the first embodiment of the present invention.

  This flowchart includes step 400 for installing the wireless device 10 using the stand 17, step 401 for confirming the installation form of the wireless device 10, and the antenna 1 vertically when the installation form of the wireless device 10 is stationary. Step 402 for setting, and Step 403 for tilting and setting the antenna 1 when the wireless device 10 is installed on the wall.

  In step 400, the stand 17 is installed in the wireless device 10. The antenna direction setting method of the present invention may be started at this timing.

  In step 401, the stand detection unit 141 detects which of the plurality of stand connection units included in the wireless device 10 is the stand 17 installed. The stand detection unit 141 detects the installation form of the wireless device 10 depending on which stand connection unit the stand 17 is connected to. The stand detection unit 141 outputs the detection result in the installation form of the wireless device 10 toward the control unit 13 as an installation form detection signal. In this example, if the wireless device 10 is stationary, the process proceeds to step 402, and if the wireless device 10 is wall-mounted, the process proceeds to step 403.

  In addition, there is no restriction | limiting in particular about the specific structure of a some stand connection part. For example, each stand connection portion may have a structure in which conduction and non-conduction between predetermined terminals are switched by connecting or removing the stand 17.

  The control unit 13 stores a table in advance therein. This table is for referring to information related to the optimal direction of the antenna unit for each installation mode of the wireless device 10. In addition, it is preferable that the combination of the installation form of the radio | wireless apparatus 10 and the optimal antenna direction has been investigated beforehand, and does not need to obtain | require by the control part 13 calculating.

  In step 402, the control unit 13 inputs an installation state detection signal for a stationary state output from the stand detection unit 141. Based on the table, the control unit 13 generates and outputs an antenna direction setting signal for a stationary state corresponding to the installation form detection signal.

  The antenna direction setting unit 12 includes a servo (not shown). The servo is for changing the direction of the antenna 111, but there is no particular limitation on the structure and operation thereof. For example, the servo may have a structure that includes a motor that rotates in response to a signal supplied from the outside and changes the direction of the antenna 111 by the rotation of the motor.

  The antenna direction setting unit 12 inputs an antenna direction setting signal for a stationary state output from the control unit 13. The antenna direction setting unit 12 uses the servo to set the direction of the antenna 111 relative to the wireless device 10 to an optimum vertical direction when the wireless device 10 is in a stationary state according to the antenna direction setting signal.

  The antenna direction setting unit 12 may further include an antenna direction detection unit that is not shown. The antenna direction detection unit is for detecting the direction of the antenna 111, but there is no particular limitation on the structure and operation thereof. The antenna direction detection unit may use, for example, a rotary potentiometer that shares the rotation axis with the antenna 111. In this case, the angle of the antenna 111 can be indirectly measured by measuring the voltage divided by the potentiometer.

  The antenna direction setting unit 12 may detect the direction of the antenna 111 with respect to the wireless device 10 using an antenna direction detection unit. Depending on the detection result, the antenna direction setting unit 12 may control whether the direction of the antenna 111 is changed. As a specific method, the antenna direction setting unit 12 may control the rotation of the servo, or may control the control unit 13 to output an antenna direction setting signal.

  The only difference between step 403 and step 402 is that the wireless device 10 is not in a stationary state but in a wall hanging state. Therefore, the stand detection unit 141 outputs an installation form detection signal for the wall hanging state, the control unit 13 outputs an antenna direction setting signal for the wall hanging state, and the antenna direction design unit 12 sets the direction of the antenna 111 with respect to the wall. The angle is set to 45 degrees, for example.

  FIG. 5 is a side view for explaining an example of an optimum direction in which the antenna 111 is set when the wireless device 10 according to the first embodiment of the present invention is installed in a wall-mounted state.

  When the direction of the antenna 111 is set in step 402 or step 403, a series of operations in the antenna direction setting method of the present invention ends.

  The radio circuit unit 15 generates and outputs a radio signal to be output from the antenna 111. The radio signal is supplied to the antenna 111. At this time, the radio signal may be supplied to the antenna 111 via the antenna direction setting unit 12 or may be supplied directly to the antenna 111 without passing through the antenna direction setting unit 12.

  There is no restriction | limiting in particular about the specific structure of the radio | wireless circuit part 15. FIG. However, the present invention is particularly effective when the wireless device 10 operates as, for example, a wireless LAN router device. This is because once the wireless LAN router device is installed, it is often used as it is, and therefore, it is rare to improve the characteristics of the antenna unit by changing the installation location.

  It should be noted that the specific configuration of the wireless circuit unit 15 is well known to those skilled in the art, including the case of a wireless LAN router device, and further, the essential features of the present invention are not directly related. Therefore, the description is omitted.

  The case where there is one antenna 111 has been described so far, but there may be a plurality of antennas 111. In this case, there may be a plurality of antenna direction setting units 12 corresponding to each of the antennas 111, and one antenna direction setting unit 12 may set the directions of the plurality of antennas 111.

  Although the case where the antenna 111 is a linear antenna has been described so far, the antenna 111 may be other than a linear shape, for example, a planar shape or a parabolic shape. In this case, the setting direction for optimizing the characteristics of the antenna 111 is naturally different between when the wireless device 10 is installed in a stationary state and when it is installed in a wall-mounted state. The relationship between the shape and the optimization of characteristics in the antenna 111 is not directly related to the essence of the present invention, and is well known to those skilled in the art, and thus detailed description thereof is omitted. .

(Second Embodiment)
FIG. 6 is an overhead view when the wireless device 10 according to the second embodiment of the present invention is installed in a stationary state.

  FIG. 7 is an overhead view when the wireless device 10 according to the second embodiment of the present invention is installed in the horizontal position.

  Compared with the wireless device 10 according to the first embodiment, the wireless device 10 according to the present embodiment includes an angle sensor 142 instead of the stand detection unit 141 as an installation form detection unit.

  FIG. 8 is a schematic circuit diagram of the wireless device 10 according to the second embodiment of the present invention. The wireless device 10 includes an angle sensor 142, a control unit 13, an antenna direction setting unit 12, an antenna 111 as an antenna unit, and a wireless circuit unit 15.

  The angle sensor 142 is connected to the control unit 13. The control unit 13 is connected to the antenna direction setting unit 12. The antenna direction setting unit 12 is connected to the antenna 111. The radio circuit unit 15 is connected to the antenna 111 via the antenna direction setting unit 12. Note that the radio circuit unit 15 and the antenna 111 may be directly connected without using the antenna direction setting unit 12.

  The angle sensor 142 detects the installation form of the wireless device 10 as angle data with respect to the vertical direction of the wireless device 10. The angle sensor 142 outputs installation angle data of the wireless device 10. Although it is ideal to detect each component in three directions orthogonal to each other as the angle data, if the actual installation form of the wireless device 10 is limited, the number of direction components may be three or less. In some cases. In the case where the installation form of the wireless device 10 is considered to be one of two types, for example, the stationary state of FIG. 6 and the horizontal state of FIG. 7, the angle sensor 142 has only one direction component. It can be said that it is sufficient to detect angle data.

  The control unit 13 inputs installation angle data output from the angle sensor 142. The controller 13 outputs an antenna direction setting signal for setting the direction of the antenna 111 based on the input installation angle data. For example, as in the stationary state in FIG. 6 or the horizontal state in FIG. 7, the control unit 13 outputs an instruction for vertically setting the antenna 111 as an antenna direction setting signal.

  The antenna direction setting unit 12 receives an antenna direction setting signal output from the control unit 13. The antenna direction setting unit 12 sets the direction of the antenna 111 with respect to the wireless device 10 according to the antenna direction setting signal.

  When the direction of the antenna 111 is set, the operation of setting the direction of the antenna 111 in the wireless device 10 ends.

  The radio circuit unit 15 generates and outputs a radio signal to be output from the antenna unit. The radio signal is supplied to an antenna 111 serving as an antenna unit.

  Other features of the wireless circuit unit 15 are the same as those of the first embodiment of the present invention, and thus the description thereof is omitted.

(Third embodiment)
The wireless device 10 according to the third embodiment of the present invention is different from the first or second embodiment in the method of setting the direction of the antenna 111. The control unit 13 in the present embodiment does not transmit an instruction for setting the direction of the antenna 111 toward the antenna direction setting unit 12, but transmits the instruction to the slave unit 20 that performs wireless communication with the wireless device 10. .

  FIG. 9 is a schematic diagram for explaining the operation of the radio apparatus 10 and the antenna direction setting method according to the third embodiment of the present invention.

  First, as in the first or second embodiment, the stand detection unit 141 or the angle sensor 142 as the installation form detection unit detects the installation state of the wireless device 10. The result of this detection is transmitted to the control unit 13 as an installation form detection signal.

  Next, the control unit 13 determines the optimal direction of the antenna 111 according to the installation form of the wireless device 10. The determination result of the control unit 13 is notified to the handset 20 that wirelessly communicates with the wireless device 10.

  Here, the determination result of the control unit 13 is preferably sent to the radio circuit unit 15 and notified to the slave unit 20 as a radio signal via the antenna 111, for example.

  After the determination result of the control unit 13 is notified to the slave unit 20, the slave unit 20 is notified to the user. At this time, the subunit | mobile_unit 20 may convey visually using the display apparatus 21 etc. with respect to a user, and may convey it auditorily using the speaker etc. which are not shown in figure.

  As a more specific example, a driver program executed on the handset 20 side in order to use the wireless device 10 of the present invention can be considered. In this case, a predetermined driver program is executed in the handset 20 when communication with the wireless device 10 of the present invention is performed. At this time, it is desirable that the driver program is automatically executed. The radio apparatus 10 of the present invention sends a predetermined signal from the control unit 13 to the slave unit 20 via the radio circuit unit 15 and the antenna unit when starting communication in response to a request from the slave unit 20. The driver program that has received this signal notifies the user of the optimum direction of the antenna visually or audibly in accordance with the signal from the control unit 13.

  Here, the following examples are conceivable as contents transmitted from the slave unit 20 to the user. If the installation form detection unit 14 detects that the wireless device 10 is hung on the wall, “If the wall on which the wireless device is installed contains metal objects, tilt the antenna to 45 degrees. It is preferable to notify the user from the slave unit 20 such as “If the metal object is not included, please stand the antenna vertically”. In order to make it easier for the user to understand, it is desirable to illustrate the same notification content using the display device 21 of the child device 20. At the same time, the same notification content may be played as voice.

  In this embodiment of the present invention, the user can manually adjust the direction of the antenna 111. Therefore, the antenna direction setting unit 12 does not require a servo or a motor for setting the direction of the antenna 111, and may be a simple joint.

(Fourth embodiment)
The wireless device 10 according to the fourth embodiment of the present invention differs from the first to third embodiments in the method of setting the direction of the antenna unit. In this embodiment, a plurality of fixed antennas 112 and 113 having different directions are used as the antenna unit, instead of one movable antenna 111 whose direction can be changed. In this embodiment, the antenna direction setting unit 12 is not the servo 122 for changing the direction of one movable antenna 111, but the connection destination to the radio circuit unit 15 is from a plurality of fixed antennas 112 and 113. An antenna changeover switch 123 for selection is used.

  FIG. 10 is a side view for explaining an example of an installation form of the wireless device 10 according to the fourth embodiment of the present invention. In this figure, a wireless device 10 includes a substrate 16, a wireless circuit unit 15, an antenna changeover switch 123 as an antenna direction setting unit 12, a first built-in antenna 112 and a second built-in antenna 113 as antenna units. , A stand 17 and a stand detector 141 as an installation form detector 14 (not shown). The number of built-in antennas 112 and 113 is not limited to two and may be two or more.

  The radio circuit unit 15 on the substrate 16 is connected to the first built-in antenna 112 and the second built-in antenna 113 via the antenna changeover switch 123. There is no particular limitation on the switching state of the antenna selector switch 123. For example, there may be a switch state in which the radio circuit unit 15 is connected only to the first built-in antenna 112, or there may be a switch state in which only the second built-in antenna 113 is connected. Similarly, there may be a switch state connected to both built-in antennas 112 and 113. Furthermore, if there are two or more built-in antennas, there can be a switch state of any connection combination.

  The wireless device 10 is installed in a wall-mounted state via a stand 17. The stand 17 is connected to a stand detection unit 141 as an installation form detection unit 14 (not shown), and it is detected that the installation form of the wireless device 10 is in a wall-hanging state.

  The antenna direction setting unit 12 in this embodiment includes an antenna changeover switch 123 for switching the connection between the plurality of built-in antennas 112 and 113 and the radio circuit unit 15. That is, in the fourth embodiment of the present invention, diversity switching using a part of a plurality of antennas is performed in order to change the characteristics of the antenna unit.

  In the example of FIG. 10, the first built-in antenna 112 is arranged so as to obtain optimum antenna characteristics when the wireless device 10 is installed in a stationary state. On the other hand, the second built-in antenna 113 is arranged so as not to be easily affected by the wall when the wireless device 10 is installed in a wall-mounted state.

  In this figure, the wireless device 10 is installed in a wall-mounted state. Therefore, it is desirable that the antenna selector switch 123 be in a state in which the radio circuit unit 15 is connected to the second built-in antenna 113.

  FIG. 11 is a block diagram for explaining a configuration of a wireless device 10 according to the fourth embodiment of the present invention. The wireless device 10 in this embodiment includes two built-in antennas 112 and 113 as antenna units, and an antenna changeover switch as the antenna direction setting unit 12. Other features in the configuration of the wireless device 10 are the same as those in the first embodiment, and a description thereof will be omitted. Here, the number of built-in antennas is not limited to two and may be two or more.

  This switching is performed once before the communication between the wireless device 10 and the child device 20 is established, but can be repeated further during the subsequent communication. That is, the connection relationship between the radio circuit unit 15 and the plurality of built-in antennas 112 and 113 may be switched according to the radio wave condition. Although this is a so-called diversity system, it is not directly related to the essence of the present invention, and hence further explanation is omitted.

  The plurality of embodiments described so far can be freely combined within a technically consistent range.

  When the first embodiment is regarded as a basic form, in the second embodiment, the angle sensor 142 is used as the installation form detection unit 14 instead of the stand detection unit 141.

  In the third embodiment, instead of automatically setting the antenna direction by the servo 122 as the antenna direction setting unit 12, a method of notifying the antenna setting direction by the user on the display device 21 of the slave unit 20 is used. .

  In the fourth embodiment, instead of using the antenna 111 whose direction can be physically changed by the servo 122 of the antenna direction setting unit 12 as the antenna unit, the connection can be switched by the antenna changeover switch 123 and the installation direction can be changed. Different antennas 112 and 113 were used.

  These three types of changes are independent of each other and can be freely combined.
