Explanation of the working process of the car anti-theft device with mobile alarm and wireless positioning function: the identification device sends out the identification key signal regularly, and the main body of the anti-theft device receives the signal within the set distance range, and then confirms the key after verifying the key. It is issued by a legal user, and the main body of the anti-theft device automatically disarms the fortified state, that is, the ZIGBEE control module with identification capabilities and communication functions does not send a signal to the low-power microprocessor module to enter the fortified state; when it is not received within the set distance range When the signal is sent by other identification devices, the ZIGBEE control module with identification capability and communication function automatically sends a signal to the low-power microprocessor module, and the low-power microprocessor module opens and enters the fortified state. When the car is moved Before the vibration occurs, the all-phase vibration switch module is in the conduction state and does not trigger the low-power microprocessor module to work. After the car is moved and vibrates, the all-phase vibration switch module will be disconnected instantly, which can trigger the low-power microprocessor module. The sensor module works and enters the alarm recognition state. The low-power microprocessor module scans the state changes of the all-phase vibration switch module regularly according to the frequency requirements set by the software. After reaching or exceeding the set value within a certain period of time, the low-power The microprocessor module sends a power-on command to the GSM power supply control module to the GSM communication processing function module. The GSM communication processing function module starts and works, and sends an alarm signal to the set mobile phone through the GSM built-in antenna. According to the current situation, decide whether to call the police to the public security department.

The identification device using ZIGBEE wireless communication technology and password identification technology is in a state of low power consumption when working, and regularly sends out the identification key and the main body of the anti-theft device hidden on the vehicle with mobile alarm function and wireless positioning function. Key check to determine the legitimacy of the user. Within the set distance (generally within 50 meters), when the main body of the anti-theft device receives the correct key signal from the identification device, the main body of the anti-theft device will automatically turn off the alarm Function: when the identification device is far away from the car (outside the set distance range), the main body of the mobile alarm anti-theft device is automatically activated and enters the waiting state. At this time, if there is an illegal person moving the vehicle, the main body of the anti-theft device will activate the built-in GSM communication unit, and the GSM communication unit can use the mobile communication network to send the alarm information to the user by sending text messages and dialing the designated number of mobile phones. Alarm function. If the user wants to know the specific location of the vehicle, he can open the "personal positioning service" of the mobile company, and use the mobile phone to inquire about the location of the vehicle. Due to the utilization of ZIGBEE technical characteristics and working in a low power consumption state, the working time of the anti-theft device main body and the identification device can be very long (up to more than two years). It is worth noting that ZIGBEE technology provides data integrity check and authentication functions. The encryption algorithm adopts AES-128, the key length is 128bit, and the factory setting is one-to-one correspondence, which eliminates the possibility of copying and can flexibly determine its security attributes . The above technologies ensure the security of communication between the main body of the anti-theft device and the identification device, and will not be used by others. The use of the car anti-theft device is to place the identification device and the main body of the anti-theft device on the legal user and hide them on the car respectively. They are small in size, easy to carry and hide; when the user uses the vehicle, the main body of the anti-theft device will not give an alarm, but when someone else moves the vehicle, the main body of the anti-theft device will give an alarm; the built-in antenna of ZIGBEE is a high-gain antenna; the power control module contains high-efficiency High performance, miniaturized lithium battery and power control and voltage alarm chip, users can monitor the power status through commands.

The all-phase vibration switch module in the main body of the anti-theft device is in the conduction state under normal conditions, and the switch module will be disconnected instantly due to the influence of external force. When the vibration switch module is disconnected, it can trigger the low-power microprocessor to work and enter the alarm recognition state; if the switch module is continuously subjected to external force, this disconnection will continue to appear, which is a low-power microprocessor module. Provide the basis for identifying alarms.

The low-power microprocessor module with trigger function is in a low-power sleep state when there is no trigger signal. The standby current at this time is generally less than 20 microamperes, which ensures that the main body of the anti-theft device can work for a long time. When the ZIGBEE control module with identification capability and communication function does not receive the signal command from the identification device, the anti-theft device enters the waiting state. At this time, if the all-phase vibration switch module is instantaneously disconnected due to external force, it can trigger the low power switch module. consumption of microprocessor modules. The low-power microprocessor regularly scans the state changes of the all-phase vibration switch module according to the requirements of software design. When the vibration switch reaches the value set by the designer within a certain period of time, the low-power microprocessor module will pass the GSM The power supply control module powers up the GSM communication processing function module, and starts the GSM communication processing function module to work.

The ZIGBEE control module and ZIGBEE built-in antenna with identification capability and communication function mainly complete the wireless connection and key identification between the main body of the car anti-theft device with mobile alarm and wireless positioning functions and the identification device, and are responsible for managing the anti-theft state. On, it interfaces with a low-power microprocessor module with processing capabilities.

The GSM communication processing function module is the core of the alarm device, and it is responsible for transmitting alarm messages and signals to the user's mobile phone through the mobile company's system. When the low-power consumption microprocessor module recognizes that the object is in the state of illegal movement, it immediately powers up the module, and the module can automatically send prompt messages and signals to the mobile phone number set in advance of the anti-theft device according to its own functions. At the same time, using the built-in functions of the module itself, the positioning function of the anti-theft device can be realized through the positioning service opened by the mobile company. Because the module has processing capabilities, it can also execute user commands related to positioning, timing, key modification, and alarm according to user needs.

The power control module provides a set of highly reliable power supply for the management controller. It uses a 2000mAh square lithium-manganese battery to ensure that the anti-theft device can work continuously for 2-3 years.
