Description

Intelligent door lock keyboard and anti-disassembly alarm method and device of intelligent device

Technical Field

The invention belongs to the technical field of theft prevention, and particularly relates to an anti-disassembly alarm method and device for an intelligent door lock keyboard and an intelligent device.

Background

At present, the anti-theft/anti-dismantling devices on the market are various, and the common anti-dismantling methods mainly comprise two methods. The first anti-dismantling method is that a mechanical switch is adopted, the state of the mechanical switch changes when equipment is correctly installed and dismantled, and whether the equipment is normally installed and dismantled is judged by acquiring the change state of the mechanical switch; the second anti-disassembly method is to use a sensor, for example, a hall sensor, place the hall sensor in the device to be anti-disassembled, set a magnet on the installation surface of the device to be anti-disassembled, and obtain the installation and disassembly state by detecting the state of the hall sensor, and of course, also use other sensors such as the geomagnetic sensor or the additional sensor to perform anti-disassembly alarm.

However, in the first tamper-proof method, if the mechanical switch is removed while being held by an external mechanical tool, a tamper alarm cannot be issued; in the second anti-dismantling method, considering that the hall sensor can only detect a magnetic field and cannot distinguish the magnets generating the magnetic field, dismantling is performed under the condition that the hall sensor can always detect the magnetic field by using another magnet, so that the situation that the anti-dismantling alarm fails can be caused.

Therefore, it can be seen that the method adopted in the market for the anti-tamper alarm has great disadvantages, and is particularly characterized in that the method is easy to damage when in preventive detachment, and once the anti-tamper device is maintained in a fixed state through external interference, the anti-tamper alarm function is easy to fail, so that the problem of poor anti-tamper alarm performance is caused, especially for an intelligent door lock keyboard installed outside a door, the safety requirement is very high, and if the intelligent door lock keyboard is detached by other people, the problem of potential safety hazard is easy to cause.

In one embodiment of the present invention, the tamper alarm method described in this application may be applied in the application environment as shown in fig. 1. The intelligent door lock keyboard 102 is a device which needs to be protected against disassembly, and the intelligent door lock keyboard 102 is mounted on a mounting surface 104 on a position such as an outer wall of the door in a screw connection mode and the like, and is used for communicating with a lock control device in the door and controlling the lock control device to open the door lock from the inside of the door. The card reading device 101 is originally configured inside the smart door lock keypad 102. If the card reading device 101 is not originally configured on the smart door lock keypad 102, the card reading device 101 may be installed inside the smart door lock keypad 102 for an anti-tamper alarm. In summary, in this application scenario, the card reading device 101 is installed inside the smart door lock keyboard 102. The smart IC card 103 is fixedly mounted on the mounting surface 104 or close to the mounting surface 104 in advance in a manner that the smart IC card is not easily detached, and the close to the mounting surface 104 is a wall surface at a certain distance from the smart door lock keyboard 102. The intelligent door lock keyboard 102 is installed on the installation surface 104, and after the intelligent IC card 103 is installed on the installation surface 104 or close to the installation surface 104, a certain distance is reserved between the intelligent door lock keyboard 102 and the intelligent IC card 103, so that the anti-dismounting alarm can be realized after the subsequent intelligent door lock keyboard 102 is detached.

The intelligent door lock keyboard 102 acquires electric signal change information within a preset detection range, wherein the electric signal change information is derived from an intelligent IC card 103 which is fixed on the installation surface 104 or close to the installation surface 104 in advance, and then the intelligent door lock keyboard 102 judges whether the electric signal change information is larger than a preset electric signal change threshold value; if not, the intelligent door lock keyboard 102 keeps the standby mode; then, if the determination is yes, it is further determined whether the IC card identification information of the smart IC card 103 can be read, if the determination is yes, the smart door lock keyboard 102 is kept in the standby mode, and if the determination is no, the smart door lock keyboard 102 generates a tamper alarm instruction.

In one embodiment of the present invention, as shown in fig. 2, the tamper alarm method may be applied in the application environment as shown in fig. 2. Different from the application scenario in fig. 1, in this scenario, the smart door lock keypad 102 does not originally have the card reading device 101, so that the card reading device 101 needs to be installed by itself when an anti-detachment alarm needs to be performed, and then when the card reading device 101 is installed, the smart door lock keypad 102 can be installed outside the smart door lock keypad 102, and specifically, the smart door lock keypad 102 can be installed above, below, in front of, behind, on the left side and on the right side as needed. The card reading device 101 in the smart door lock keypad 102 emits radio waves, and when there is a smart IC card 103 around the smart door lock keypad, the card reading device 101 itself detects that the threshold value of change of the electric signal (electric field intensity) is different from that when there is no smart IC card 103.

Of course, the positions of the card reading device 101 and the smart IC card 103 may also be reversed, that is, the card reading device 101 is mounted on the mounting surface 104 or close to the mounting surface 104, and the smart IC card 103 is mounted inside or outside the smart door lock keyboard 102, so that the anti-detachment alarm can be realized when the smart door lock keyboard 102 is detached.

In addition, because the intelligent IC card 103 and the card reading device 101 are small in size, the card reading device can be adapted to devices with different structures, so that the anti-dismounting and anti-theft effects are realized, and the use convenience is greatly improved.

In an embodiment of the present invention, as shown in fig. 3, there is provided a method for preventing a detachment and alarming of an intelligent door lock keyboard, where the intelligent door lock keyboard is disposed on an installation surface outside a door and is used for communicating with an intelligent lock inside the door, the intelligent lock communicates in a wireless manner (such as BLE, zigBee, and the like), a card reading device is disposed in the intelligent door lock keyboard, and the method includes the following steps:

step S100: acquiring electric signal change information in a preset detection range, wherein the electric signal change information is derived from a smart IC card which is fixed on the mounting surface in advance or is close to the mounting surface;

in this step, the preset detection range is preset and is used for limiting the detection range of the electrical signal change information. Through setting up predetermine detection range to longer mounting distance and shorter mounting distance between adaptation intelligence lock keyboard and the intelligent IC-card, and then satisfy the demand of different application scenarios.

Based on if intelligent lock keyboard is demolishd, then can produce the consideration of great signal of telecommunication change, and then earlier through acquireing signal of telecommunication change information realizes the follow-up accurate judgement whether dismantles.

Step S200: judging whether the electric signal change information is larger than a preset electric signal change threshold value or not;

in this step, the electrical signal change threshold is preset. Through the setting of the electric signal change threshold value, when the follow-up anti-dismantling judgment is carried out, the card reading operation can be continued only when the electric signal change threshold value is larger than the electric signal change threshold value, so that the electric signal change caused by fine interference can be filtered, on one hand, invalid data judgment and processing are avoided, on the other hand, the electric signal change threshold value can be set in a self-defining mode, the use flexibility can be improved, the electric signal change threshold value with different numerical values can be set to adapt to application scenes with different interference signals, and the width of the application scenes are improved.

Step S300: if not, keeping the standby mode;

if the judgment result is no, namely the judgment result is that the electric signal change information is less than or equal to the electric signal change threshold, the electric signal is slightly changed due to external interference at the moment, and the situation that theft does not occur is shown, and at the moment, the requirement of low power consumption can be met by keeping the standby mode.

Step S400: if the judgment result is yes, further judging whether the IC card identity information of the intelligent IC card can be read, if the judgment result is yes, keeping the standby mode, and if the judgment result is no, generating a tamper-proof alarm instruction.

Specifically, if yes, that is, if it is determined that the electrical signal change information is greater than the preset electrical signal change threshold, then a theft phenomenon may occur, and further determination is needed, that is, it is determined whether the IC card identity information of the smart IC card can be read, and at this time, if it is determined that the IC card identity information of the smart IC card cannot be read, it is determined that the smart IC card is far away from the smart door lock keyboard, a relative distance between the smart IC card and the smart door lock keyboard inevitably changes, and a situation that the smart door lock keyboard is detached occurs, so that a detachment alarm indication is generated at this time, and an alarm is given by the detachment alarm indication, so that efficient detachment prevention and quick alarm response are realized, and detachment prevention performance is greatly improved.

If the judgment result is yes, the IC card identity information of the intelligent IC card can be read, and the relative distance between the intelligent IC card and the intelligent door lock keyboard is not changed, so that the standby mode is kept.

The invention relates to an anti-disassembly alarm method and device for an intelligent door lock keyboard, which comprises the steps of firstly, acquiring electric signal change information in a preset detection range, wherein the electric signal change information is derived from an intelligent IC card which is fixed on a mounting surface in advance or is close to the mounting surface; then judging whether the electric signal change information is larger than a preset electric signal change threshold value or not, and further judging whether the intelligent door lock keyboard is possible to be detached or not, if not, namely judging that the electric signal change information is smaller than the electric signal change threshold value, then the electric signal change caused by the interference of other IC cards is possible at the moment, but the intelligent door lock keyboard is not detached, so that the standby mode is maintained at the moment, and the requirement of low power consumption is met; if the electric signal change information is judged to be larger than a preset electric signal change threshold value, whether the IC card identity information of the intelligent IC card can be read or not needs to be further judged, if the electric signal change information is judged to be larger than the preset electric signal change threshold value, the intelligent IC card is not detached at the moment, the standby mode is kept, if the electric signal change information is judged to be not larger than the preset electric signal change threshold value, the situation that the identity information of the intelligent IC card cannot be read due to the fact that the relative position between the intelligent IC card and the intelligent door lock keyboard possibly changes at the moment is shown, namely the situation that the intelligent door lock keyboard is detached occurs, then an anti-detachment alarm indication is generated, efficient anti-detachment and quick alarm response are achieved, and anti-detachment performance is greatly improved.

In one embodiment of the present invention, step S100: acquiring electric signal change information in a preset detection range; the method specifically comprises the following steps:

and acquiring the electric signal change information between the current moment and the previous moment in a preset detection range.

Specifically, in this step, taking time points as an example, when there are n time points, that is, time points t1, t2, t3, and t4.. Time point tn, the current time is time point t2, and the previous time is time point t1. That is, the previous time is a time previous to the current time.

The current moment and the previous moment respectively correspond to an electric signal in the preset detection range, once the intelligent door lock keyboard is detached, the electric signal changes, and then whether the detachment condition occurs or not is conveniently judged by detecting the change information of the electric signal.

Specifically, the electrical signal change information is information of a change in electrical signal between a current time and a previous time. In this embodiment, when the relative position between the smart IC card and the smart door lock keyboard is not changed, the electrical signal from the smart IC card is not changed, at this time, the electrical signal change information is not changed or is changed little, and if the relative position is changed, the electrical signal change information is changed greatly.

Or, the electrical signal change information further has another acquisition mode, specifically: and acquiring the electric signal change information between the electric signal at the current moment and the preset signal in the preset detection range.

The preset signal is a preset normal electric signal in the preset detection range when the intelligent door lock keyboard is not detached, the preset signal is set to serve as a reference signal, the electric signal at the current moment is obtained in real time and compared with the preset signal, then the electric signal change information is obtained, only the electric signal at the current moment needs to be obtained in real time, the electric signal at the previous moment does not need to be recorded, and subsequent anti-detachment judgment can be achieved through comparison with the preset signal.

In an embodiment of the present invention, as shown in fig. 4, the acquiring the change information of the electrical signal within the preset detection range further includes:

step S011: acquiring IC card identity information of a smart IC card fixed on the mounting surface or close to the mounting surface in advance, and storing the IC card identity information;

in this step, the card reading operation of the intelligent IC card is conveniently carried out subsequently by storing the identity information of the IC card.

Step S012: after the IC card identity information is stored, a ciphertext write-in instruction is generated;

step S013: sending the ciphertext writing instruction to the intelligent IC card, wherein the ciphertext writing instruction is used for writing a preset ciphertext into a specified storage area of the intelligent IC card and setting a current secret key;

in this step, the preset ciphertext is written in the designated storage area, and a secret key is also set, so that information storage and binding of the intelligent IC card are realized, the intelligent IC card is identified by specific equipment, namely card reading equipment in the intelligent door lock keyboard, and interference of other IC cards is filtered.

Step S014: generating a read-write protection instruction, and sending the read-write protection instruction to the intelligent IC card, wherein the read-write protection instruction is used for carrying out access protection on a specified storage area of the intelligent IC card.

In this step, access protection is performed on the designated storage area of the smart IC card based on the read-write protection instruction, so that the smart IC card cannot be copied, reliability of tamper-proof early warning is improved, possibility of tamper-proof cracking is reduced, and use requirements are met.

Specifically, compared with the problems of inaccurate anti-disassembly and poor anti-disassembly alarm effect easily caused by the fact that a common IC card is used for anti-disassembly in the prior art, the intelligent IC card has the functions which are not possessed by the intelligent IC card in the prior art by storing the identity information of the intelligent IC card and then carrying out access protection on the appointed storage area of the intelligent IC card, and the intelligent IC card cannot be copied because the access protection and the current secret key are set and stored, so that the problem of poor effect in the process of utilizing the intelligent IC card for anti-disassembly alarm in the prior art is solved, and the reliability and the accuracy of the anti-disassembly alarm are improved.

In one embodiment of the present invention, step S014: after the step of sending the read-write protection instruction to the smart IC card, the method further includes:

and self-adaptively setting the current working parameters matched with the position of the mounting surface through the loop iteration of the step of adjusting the parameters of the card reading equipment and the step of reading the intelligent IC card.

Specifically, the step of adjusting the parameters of the card reading device is a step of adjusting the parameters of the card reading device, and the step of reading the smart IC card is a step of reading information of the smart IC card after the parameters of the card reading device are adjusted, that is, the step is performed by repeating the following steps: the method comprises the steps of firstly setting card reader parameters and then reading information of the intelligent IC card, and further realizes that the current working parameters matched with the installation surface position are set under the multiple debugging.

Further, the effect achieved after the current working parameters matched with the installation surface position are set in a self-adaptive mode is as follows: the set current working parameters can ensure that the card reading equipment can stably read the identity information of the intelligent IC card with the minimum card reading power.

Therefore, in this embodiment, after the step of sending the read-write protection instruction to the smart IC card, the setting of the current working parameter is realized through the loop iteration of the step of adjusting the card reading device parameter and the step of reading the smart IC card, so that the current mounting surface position can be matched, and the compatibility of the application scene is further improved.

Specifically, the current operating parameters include, but are not limited to, minimum read power, information acquisition sensitivity, and electrical signal change threshold.

In an embodiment of the present invention, after the step of sending the read-write protection instruction to the smart IC card, the method further includes the following steps:

firstly, acquiring parameter setting information for setting working parameters;

and then, generating current working parameters according to the parameter setting information, wherein the current working parameters comprise but are not limited to minimum card reading power, information acquisition sensitivity and an electric signal change threshold value.

In this step, the current working parameters may also be specifically set as required, that is, the parameter setting information, such as directly setting the minimum card reading power, the information acquisition sensitivity, and the electrical signal change threshold, thereby implementing custom setting of the current working parameters, enabling anti-removal devices of different structures in different application scenarios to be targeted, and further improving compatibility of the application scenarios.

In an embodiment of the present invention, as shown in fig. 5, before acquiring the change information of the electrical signal within the preset detection range, the method further includes:

step S021: acquiring set electric signal detection power;

step S022: and generating a preset detection range according to the set electric signal detection power.

In this embodiment, the preset detection range is set by setting the electric signal detection power, the larger the electric signal detection power is, the larger the preset detection range is, and the smaller the electric signal detection power is, the smaller the preset detection range is, and the preset detection range includes a preset card reading distance and a preset field strength detection distance. Through the arrangement of the electric signal detection power and the preset detection range, the recognition between the intelligent IC card and the card reader can be met under the condition that different anti-dismounting devices have different mounting structures.

In one embodiment of the invention, step S100: the method for acquiring the electric signal change information in the preset detection range specifically comprises the following steps:
