Detailed ways

Please refer to FIG. 1 , which is a unit block diagram of the first embodiment of the present invention.

As shown in FIG. 1 , the mobile phone with security and anti-theft function has an induction processing unit 1 on the mobile phone body, and the main control unit 3 of the mobile phone is also shown in the figure. In addition, the mobile phone body is equipped with an inductive element 2 independent of the mobile phone.

The primary function of the sensing processing unit 1 is to receive sensing signals from the external space. When the sensing processing unit 1 fails to receive the sensing signals correctly, it immediately sends a sensing signal disappearance signal to the mobile phone control unit. Meanwhile, in this embodiment, the sensing processing unit 1 is also used to send an excitation signal, and the excitation signal is used to excite the sensing element 2 to generate a sensing signal. The induction processing unit 1 can share the power supply with other parts of the mobile phone body, or can have its own independent power supply. In the latter case, the induction processing unit 1 can work normally no matter whether the mobile phone is in the power-on state. Considering that the mobile phone may not always be powered on, but the privacy protection and anti-theft functions of the mobile phone need to be available at all times, therefore, in this embodiment, the mobile phone is powered by an independent power supply. The induction processing unit 1 consumes very little power when working, which will not cause inconvenience to the user.

As shown in FIG. 1 , the sensing processing unit 1 specifically includes an excitation signal sending unit 11 , a sensing signal receiving unit 12 , and a notification unit 13 .

The excitation signal sending unit 11 is configured to continuously send the excitation signal to the outside. The excitation signal is in the form of a signal that can be transmitted wirelessly and has better penetrating performance. In this embodiment, an electromagnetic signal is preferably used. The frequency of the electromagnetic signal is fixed and is set as the first frequency. Further, the first frequency may be a 125kHz electromagnetic signal used by a common inductive card reader. The transmission power of the electromagnetic signal does not need to be very large, and can be limited to a range of 1-3 meters according to actual needs.

The induction signal receiving unit 12 is used to receive an external induction signal, and after receiving the induction signal, check whether the identification code in the induction signal is correct, and when the identification code is correct, send the induction signal and receive the signal. The external induction signal is usually a signal of the same form as the excitation signal, but should be distinguishable from the excitation signal. In this embodiment, the induction signal is an electromagnetic induction signal, and its frequency is the second frequency. Further, the second frequency is a modulation signal of 62.5kHz adopted by the proximity card of the card reader. In this embodiment, in order to effectively identify the sensing signal sent by the corresponding sensing element 2 of the mobile phone, the sensing signal needs to include identification code information. The identification number is a code unique to the phone that sets it apart from other phones. The sensing signal receiving unit 12 first checks the identification code after receiving the sensing signal, and only sends the sensing signal received signal only if the identification code is correct.

The notification unit 13 is used to receive the sensing signal received signal, and when the signal is not received for a period of time, send the sensing signal disappearance signal to the mobile phone main control unit 3, and start the mobile phone to perform corresponding processing.

After the main control unit 3 of the mobile phone receives the disappearance signal of the induction signal, it controls the actuators to perform corresponding processing according to the setting of the phone owner. If the mobile phone enters the locked state after the induction signal is set by the owner and disappears, the main control unit 3 controls the mobile phone to enter the locked state; if the mobile phone enters the alarm state after the induction signal disappears, the main control unit 3 controls the mobile phone to alarm. , including ringing the horn, sending out alarm bells, flashing the mobile phone, etc.; if the owner sets the induction signal to disappear, and the mobile phone enters the lock and alarm state at the same time, then the main control unit 3 controls the mobile phone to alarm and locks the mobile phone; It can be set to lock first, then alarm, etc. In short, after the induction signal disappears, the mobile phone can start various processing processes according to the settings of the owner.

The sensing element 2 independent of the mobile phone is an element independent of the mobile phone matched with the mobile phone body, the sensing element 2 can generate the sensing signal, and the sensing signal can be transmitted wirelessly for a certain distance in space, and the distance is about It can be within 1-3 meters. If the distance is too large, the alarm cannot be reported in time. If the distance is too small, false alarms will occur. In this embodiment, the sensing element 2 is preferably used to generate the sensing signal after receiving the excitation signal sent by the sensing processing unit 1 of the mobile phone body, for example, a sensing card commonly used at present. This method is commonly used by various IC card readers at present, and its advantage is that the induction signal does not need its own power supply. In this embodiment, the sensing element 2 includes an excitation signal receiving unit 21 and an induction signal sending unit 22 . Of course, the desired effect can be achieved by using an inductive element with its own power supply that actively sends out an inductive signal.

The excitation signal receiving unit 21 is used to receive the excitation signal sent by the mobile phone body; and generate an excitation signal received signal output accordingly.

The sensing signal sending unit 22 is configured to receive the excitation signal received signal, and send the sensing signal accordingly.

In this embodiment, the induction element 2 adopts an induction card. At this time, the excitation signal receiving unit 21 is specifically an electromagnetic coil of an induction card, and the induction signal sending unit 22 is an application-specific integrated circuit, which stores a unique digital identification number input during manufacture, and the application-specific integrated circuit When electrified, the identification number will be formed into a 62.5kHz modulation signal and output as an induction signal. The working principle of the inductive element 2 in the form of the above-mentioned inductive card is that when the excitation signal exists in the space, the electromagnetic coil in the inductive card generates a weak current under the induction of the excitation signal, and this current has been received as the excitation signal. signal, and at the same time as the power supply of the integrated circuit, input to the power supply terminal of the integrated circuit, so that the integrated circuit can be powered on. When the integrated circuit is powered on, it automatically sends out a 62.5kHz electromagnetic modulation signal with the identification code information, and the modulation signal is the induction signal.

The size of the proximity card can be made very small, and it is designed as a portable ornament, etc., so that the owner of the device can carry it easily.

The working process of the privacy protection or anti-theft function of the mobile phone is as follows.

The mobile phone owner obtains the mobile phone body and the proximity card as the sensing element 2 at the same time when purchasing the mobile phone. Usually, the proximity card is separated from the mobile phone body and placed close to the owner, and the sensing processing unit 1 of the mobile phone body will not perform any special processing because it can obtain the sensing signal generated by the proximity card at any time. When the distance between the mobile phone body and the induction card is too far, exceeding the effective transmission distance of the induction signal, or exceeding the effective transmission distance of the excitation signal, the induction processing unit 1 will not be able to receive the induction signal, and will send an induction signal disappearance signal to The main control unit 3 of the mobile phone, under the control of the main control unit 3, the mobile phone body performs special processing such as locking or alarming according to the setting of the owner. After entering the above-mentioned special processing state, if the mobile phone body receives the sensing signal again, the mobile phone exits the special processing process, including unlocking the state or stopping the alarm.

The working principle of the mobile phone privacy protection has been described above. In addition, in order to make the mobile phone execute this function correctly and deal with some special situations, the mobile phone of this embodiment also has some auxiliary functions.

First of all, the mobile phone has a release password. When the owner of the mobile phone keeps the proximity card away from the mobile phone due to his own reasons, he can input the release password to release the lock and other special processing states of the mobile phone. Of course, this function may not be provided, so that the mobile phone can exit the above-mentioned special processing state only after receiving the sensing signal sent by the sensing element again.

In addition, the specific content of the special treatment can be selected by the owner. For example, the special processing can be to only lock the mobile phone; it can also be to only report to the police; it can also be controlled by the mobile phone main control unit 3 to enter the locked state when the alarm is generated; it can also be after the induction signal disappears. , and the phone is still locked after a certain period of time.

In addition, menu options and special external switches can also be set, and whether the mobile phone uses the functions provided by this embodiment is set through the menu or external switches.

In the above embodiments, the working mode of the current IC card reader is preferably used. In fact, it is also possible to use an inductive element with its own power supply that actively sends out an inductive signal. At this time, the sensing processing unit of the mobile phone body only needs to have the sensing signal receiving function. Of course, this method may increase the size of the sensing element and reduce its service life, which is obviously not as superior as using the current general-purpose passive induction card.

The following second embodiment provides the working method of the mobile phone with the above functions. Including when the mobile phone is in the standby state, due to the disappearance of the sensing signal, it enters the process of special processing such as locking or alarming; and the process of the mobile phone exiting the special processing state after receiving the sensing signal again.

Figure 2 shows the steps for the mobile phone to enter a special processing procedure.

In step S201, the mobile phone is in a normal standby state.

At this time, the induction processing unit in the mobile phone continuously sends out the excitation signal, and after receiving the excitation signal, the induction element matched with the mobile phone continuously sends out the induction signal. The mobile phone receives the induction signal and thinks that the mobile phone is at the owner's side, so it is in a normal standby state.

Step S202, judging whether the sensing signal is received normally; if yes, return to step S201, continue normal standby; if not, enter step S203.

Step S203, starting a special processing procedure for the disappearance of the sensing signal.

The special processing includes pre-set content such as locking the mobile phone and making the mobile phone alarm. It can also be that the mobile phone calls the police first, and when the alarm time exceeds the set time and is still not released, the mobile phone is made to enter the locked state.

Step S204, judging whether the sensing signal returns to normal; if yes, return to step S201, and stand by normally; if not, enter step S205.

After the mobile phone enters the special processing, it still continuously sends the excitation signal and the induction signal to judge whether the induction signal returns to normal, and proceed accordingly.

Step S205, keep the locked or alarmed state.

FIG. 3 shows the process of unlocking a locked mobile phone.

In step S301, the mobile phone is in a locked state.

Step S302, the mobile phone sends an excitation signal and receives a sensing signal.

Step S303, judging whether the sensing signal has been received again, if yes, proceed to step S304; if not, return to step S301.

Step S304, the mobile phone is unlocked.

FIG. 3 also shows the unlocking process using the unlock password when the mobile phone provides the unlock password.

In step S301, the mobile phone is in a locked state.

Step S305, the mobile phone receives the input unlock password.

Step S306, judging whether the unlocking password is correct; if yes, proceed to step S304; if not, return to step S301.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
