The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
The wireless power supply technology is a non-contact wireless energy transmission mode, and comprises a transmitting end and a receiving end, wherein the transmitting end and the receiving end transmit energy from the transmitting end to the receiving end through an energy transmission medium, such as an electromagnetic field, so as to charge a battery or supply power to equipment, and in some occasions, the wireless power supply technology is also called as wireless power supply. With the development of wireless charging technology, more and more medical devices are configured with wireless charging and WLAN functions at the same time, but in the medical devices, the wireless charging and the WLAN are not directly connected, and the functions are independent of each other. Based on this, and in combination with the problems existing in the existing medical devices on the automatic WLAN connection, the inventors of the present application propose an automatic WLAN connection method and related system based on wireless power supply connection.
As shown in fig. 1, the automatic networking system 10 for medical devices according to an embodiment of the present application includes a gateway 100, a medical device 200, and a wireless power transmitting terminal 301.
The gateway 100 has a wireless and/or wired connection function to connect devices connected thereto together. In an embodiment, the gateway 100 may include a processor, a memory, a wireless communication module (e.g., a WIFI module), a USB interface, a power module, and the like, where the processor of the gateway 100 may adopt an embedded operating system Linux, iOS, or Android OS, and may process protocols and data of different communication modules, run various application programs, and the like, and for example, the WIFI module of the gateway 100 may enable a current wireless lan to access another WIFI network, and for example, the USB interface of the gateway 100 may be used to extend other wireless communication modules, such as 2.4GHz wireless, ZigBee, and Z-wave modules.
The medical device 200 may be, for example, an ultrasound imaging device, a mobile DR (Digital Radiography) device, or the like, includes a wireless power receiving terminal 201, a host 202, a wireless communication interface 203, and a network communication interface (not shown), and has a WLAN function and a wireless power function. In one embodiment, the wireless charging receiving terminal 201 mainly includes a wireless power receiving circuit and a wireless power receiving coil, and is configured to supply the received electric energy to the rest of the components of the medical apparatus 200.
In the embodiment shown in fig. 1, the wireless power transmitting terminal 301 has been connected to the gateway 100 by wire or wirelessly.
In one example, the wireless power supply transmitting terminal 301 joins a local area network by connecting the gateway 100 in a wired manner, wherein a DHCP module in the local area network allocates an IP address to the wireless power supply transmitting terminal 301 and obtains its MAC address, and then establishes a network connection, so that the wireless power supply transmitting terminal 301 can learn information such as a password required for WLAN connection. This can be done with reference to existing related network technologies, which are not limited in this application.
In another example, the wireless power transmitting terminal 301 joins a local area network by connecting the gateway 100 wirelessly, and in this case, the local area network can be accessed by using, for example, the information terminal 400 shown in fig. 3. For example, a special management program burned in advance exists in the wireless power supply transmitting terminal 301 to implement a network connection function, when the wireless power supply transmitting terminal 301 does not access a network, the wireless power supply transmitting terminal 301 can be automatically converted into a wireless hotspot for connection, the wireless power supply transmitting terminal 301 can be directly found by using the information terminal 400 and can be used as a router to connect with the router, a connection password of the wireless power supply transmitting terminal 301 needs to be input in a connection process, and then the special management program on the information terminal 400 finds the wireless power supply transmitting terminal 301 and configures a real router, a router connection password and other information (such as a user name) which need to be connected for the wireless power supply transmitting terminal 301, so that the wireless power supply transmitting terminal 301 can join a local area network through the real router. Here, the writing of each special management program may refer to the prior art as long as it can realize the functions described above, and the present application is not limited thereto.
In the case where the wireless power supply transmitting terminal 301 has joined the local area network, it is obvious that the wireless power supply transmitting terminal 301 can learn information such as the password of the gateway 100.
In the embodiment shown in fig. 1, the wireless power transmitting end 301 is paired with the wireless power receiving end 201 for use. In one example, the wireless power supply transmitting terminal 301 is connected to the wireless power supply receiving terminal 201 through a wireless power supply proprietary communication mode, that is, a wireless power supply communication link is adopted, which can realize information transmission besides electric energy transmission, so that the wireless power supply transmitting terminal 301 and the wireless power supply receiving terminal 201 establish a wireless pairing connection. For example, the wireless power receiving end 201 broadcasts a power supply requirement to the surrounding wireless power transmitting ends 301, and the wireless power transmitting ends 301 may receive the power supply requirement to respond and complete the pairing. In another example, the wireless power supply transmitting terminal and the wireless power supply receiving terminal are respectively provided with a wireless communication unit for realizing high-speed transmission of a large amount of data; in some embodiments of the present application, the transmission of the networking information is achieved through a wireless power communication link, i.e., a wireless power communication unit having a dedicated communication path.
In one embodiment, the wireless power transmitting terminal 301 mainly includes a wireless power transmitting circuit and a wireless power transmitting coil, so as to transmit the electric energy to the wireless power receiving terminal 201 as required.
In another embodiment, the medical device automatic networking system 10 has a plurality of wireless power supply transmitting terminals, each of which corresponds to a wireless power supply receiving terminal of a different medical device and is paired for use, for example, before the wireless power supply receiving terminal 201 of the medical device 200 and the wireless power supply transmitting terminal 301 realize wireless power supply, whether the medical device is an authorized device can be confirmed through wireless power supply private communication connection, if the medical device is an authorized device, the power is supplied to realize wireless power supply, and if the medical device is not an authorized device (the authorized device refers to the medical device 200 which is stored in advance by the wireless power supply transmitting terminal 301 and corresponds to the wireless power supply receiving terminal 201 to which the medical device is to be paired), the power is. For example, the identification signal is transmitted through the wireless power supply transmitting terminal, and the wireless power supply receiving terminal senses and distinguishes the identification signal; or the wireless power supply receiving end sends out an identification signal, and the wireless power supply transmitting end receives and distinguishes the identification signal to determine whether the opposite side authorizes the equipment, so that the mutual pairing of the wireless power supply receiving end and the opposite side is realized. The specific pairing, the electric energy transmission and the like between the wireless power supply transmitting end and the wireless power supply receiving end can be realized by referring to the prior art, and the application does not limit the specific pairing, the electric energy transmission and the like. In one implementation, the wireless power transmitter is typically fixedly mounted to a wall or other object.
After the wireless power supply transmitting terminal 301 and the wireless power supply receiving terminal 201 are paired, a wireless power supply communication path exists between the two terminals, which is used for transmitting electric energy on one hand and for transferring information such as passwords required by WLAN connection on the other hand. When the medical device 200 approaches the wireless power supply transmitting terminal 301, the wireless power supply module of the wireless power supply transmitting terminal 301 judges whether the medical device 200 is an authorized device, if so, the wireless power supply is started, and information such as a gateway password is sent to the host 202 of the medical device 200, so that a management program (which is burned in the medical device in advance to realize a network connection function) running in the host 202 of the medical device 200 connects to the gateway AP according to the gateway AP information, and establishes WLAN connection; if the device is not an authorized device, the wireless power supply module of the wireless power supply transmitting terminal 301 will not provide wireless power supply, and will not send gateway AP information. Here, the management program running in the host 202 of the medical device 200 may refer to the prior art as long as it can implement the functions described above, and the present application is not limited thereto. In addition, the communication protocol between the wireless power transmitting terminal 301 and the gateway 100 and the communication protocol between the medical device 200 and the gateway 100 may be any available communication protocol known in the art, and the present application is not limited thereto.
In the embodiment shown in fig. 1, after the wireless power supply transmitting terminal 301 passes through the wired/wireless connection gateway 100, when the wireless power supply transmitting terminal 301 approaches the medical device 200, it is determined whether the medical device 200 authorizes the device, and if so, the gateway AP information is transmitted through the wireless power supply communication path, so that the medical device 200 automatically establishes a connection with the gateway 100 according to the acquired gateway AP information; therefore, network connection can be completed without manual operation of a user every time, and meanwhile, the additional cost of NFC hardware is not required to be increased.
Based on the automatic networking system for medical devices shown in fig. 1, an embodiment of the present application provides a method for medical devices to automatically connect to a WLAN, as shown in fig. 2, the method includes the following steps:
step S10: and the wireless power supply transmitting terminal is accessed to the gateway, namely the wireless power supply transmitting terminal is connected with the gateway. The establishment of the specific connection is as described above, and is not described herein again.
Step S11: and the wireless power supply transmitting terminal acquires the networking information of the gateway from the gateway after connection.
Step S20: the wireless power supply transmitting terminal is made to distinguish whether the medical equipment entering the power supply range is authorized equipment. This is the authentication step, and as mentioned above, the pairing between the specific wireless power transmitting end and the wireless power receiving end of the medical device is not described in detail here.
Step S30: after the medical equipment is determined to be authorized equipment, the wireless power supply transmitting terminal establishes a wireless power supply communication link between the medical equipment and the wireless power supply transmitting terminal so as to wirelessly supply power to the medical equipment, and transmits networking information to the wireless power supply receiving terminal of the medical equipment through the wireless power supply communication link.
Step S40: and the wireless communication interface of the medical equipment is automatically connected with the gateway according to the networking information received by the wireless power supply receiving end.
As described above, according to the method for automatically connecting the medical device to the WLAN shown in fig. 2, the medical device can automatically connect to the gateway while realizing wireless power supply, and only authorized medical devices can supply power and be networked, so that the security of network communication is guaranteed.
As shown in fig. 3, the automatic networking system 10 for medical devices according to another embodiment of the present application includes a gateway 100, a medical device 200, a wireless power transmitting terminal 301, and an information terminal 400. The functions of the gateway 100, the medical device 200, and the wireless power transmitting terminal 301 are the same as those of the embodiment shown in fig. 1, and are not described herein again. The information terminal 400 may be a terminal such as a personal computer, a server, or a smart phone used by a user.
In the embodiment shown in fig. 3, the information terminal 400 is connected to the gateway 100, and the specific connection implementation is referred to in the prior art, which is not limited in this application. In the present embodiment, the information terminal 400, the wireless power supply transmitting terminal 301, and the medical device 200 all have a dedicated management program running thereon, and the three are communicated with each other through the respective dedicated management programs.
The special management program running in the wireless power transmitting terminal 301 can implement not only the function of connection between the wireless power transmitting terminal and the wireless power receiving terminal 201 and the gateway 100 (as described in the embodiment shown in fig. 1), but also the communication between the information terminal and the information terminal 400.
The special management program running in the medical device 200 can implement the function of connection between the medical device and the wireless power transmitting terminal 301 and the gateway 100, as in the embodiment shown in fig. 1.
The special management program running in the information terminal 400 can not only realize the function of enabling the wireless power supply transmitting terminal 301 to wirelessly access the gateway 100 (as described in the embodiment shown in fig. 1) as described in the embodiment shown in fig. 1, but also can realize the function of enabling a user to manually or automatically set and modify information such as a password of the gateway 100 in the present embodiment through the special management program running in the information terminal 400. In addition, the modified information can be stored in an encrypted manner by a dedicated management program running in the information terminal 400, so that the modified information can only be read after being logged in by the management program.
Here, the writing of each special management program may refer to the prior art as long as it can realize the functions described above, and the present application is not limited thereto.
In the embodiment shown in fig. 3, the wireless power supply transmitting terminal 301 communicates with the management program of the information terminal 400 through its management program, and obtains information such as a password of the gateway 100. Then, similar to the description of the embodiment shown in fig. 1, after the medical device 200 approaches the wireless power supply transmitting terminal 301, the wireless power supply module of the wireless power supply transmitting terminal 301 may determine whether the medical device 200 is an authorized device, if the medical device 200 is an authorized device, start wireless power supply, and send information such as a gateway password to the host 202 of the medical device 200, and a management program running in the host 202 of the medical device 200 connects to the gateway AP according to the AP information of the gateway 100, and establishes WLAN connection; if the device is not an authorized device, the wireless power supply transmitting terminal 301 does not provide wireless power supply, and does not send gateway AP information.
In one embodiment, after the information terminal 400 changes the password and other information of the gateway 100, the wireless power transmitting terminal 301 communicates with the management program of the information terminal 400 through the management program thereof and obtains the changed password and other information, and the WLAN connection between the medical device 200 and the gateway 100 is disconnected because the password is not correct; thus, when the wireless power supply is performed again, the management program of the wireless power supply transmitting terminal 301 retransmits a new password or the like to the host 202 of the medical device 200, so that the medical device 200 and the gateway 100 reestablish a connection.
In another embodiment, after the information terminal 400 changes the password and other information of the gateway 100, the WLAN connection between the medical device 200 and the gateway 100 may be disconnected because the password is not correct, and when the wireless power supply is performed again, the management program of the wireless power supply transmitting terminal 301 may obtain new password and other information from the information terminal 400 again and send the information to the host 202 of the medical device 200 to reestablish the connection.
Compared with the traditional mode of transmitting the AP information through NFC, the automatic networking system for the medical equipment in the embodiment shown in FIG. 3 does not need to additionally increase the hardware cost of NFC, and can complete network information updating in normal use of a user without special operation. Particularly, for medical devices, such as ultrasound images, mobile DR devices, etc., the volume and weight are usually large, and if the conventional NFC method is used, it is difficult to align and inconvenient to operate, and in addition, when information such as passwords changes, special operations are required to update the information; the automatic networking system of the medical equipment automatically completes information updating when the wireless power supply function is normally used.
Based on the automatic networking system for medical devices shown in fig. 3, an embodiment of the present application provides a method for medical devices to automatically connect to a WLAN, as shown in fig. 4, the method includes the following steps:
step S100: enabling the information terminal to access the network and establishing connection with the gateway;
step S101: the information terminal acquires networking information of the gateway;
step S110: the wireless power supply transmitting terminal and the information terminal are communicated, and the communication mode established between the wireless power supply transmitting terminal and the information terminal is as described above and is not described again;
step S111: the wireless power supply transmitting terminal acquires networking information from the information terminal;
step S120, step S130, and step S140: similar to the aforementioned steps S20, S30 and S40, respectively, are omitted for brevity.
In one embodiment, the wireless power transmitter 301 may also obtain the networking information directly from the gateway 100, for example, send an access request for obtaining the networking information to the gateway 100, and the gateway 100 sends the networking information to the wireless power transmitter 301 in response to the access request.
According to the embodiments of fig. 3 and 4, if the networking information is changed (e.g., the networking information is reconfigured by the information terminal), the wireless power transmitting terminal 301 may obtain the changed networking information through the information terminal 400.
Based on this, in one embodiment, as shown in fig. 5, the method for the medical device to automatically connect to the WLAN further includes:
step S201: enabling the wireless power supply transmitting terminal 301 to actively send a handshake signal to the gateway 100 at preset time intervals;
step S202: if the sending of the handshake signal fails, the wireless power supply transmitting terminal 301 sends a networking information request message to the information terminal 400 after the sending of the handshake signal fails;
step S203: causing the wireless power supply transmitting terminal 301 to receive the updated networking information from the information terminal 400;
step S204: the wireless power supply transmitting terminal 301 is caused to transmit updated networking information to the wireless power supply receiving terminal 201 paired within its power supply range, so that the corresponding medical device 200 is caused to establish connection with the gateway 100 again according to the updated networking information.
