The WIFI module 3 is located at the inner top of the housing 9. The signal output ends of the G-SENOR module 4, the thermometer sensor 5 and the barometer 6 are connected to the input end of the microcontroller and are arranged side by side below the microcontroller 1. The power supply module 7 is located at the inner bottom of the housing 9. The housing 9 encloses each component.

[0037] Further, the microcontroller 1 includes a microcontroller chip 101, a communication interface 102, and a memory 103. The microcontroller chip 101 is located at the center of the microcontroller 1 and is used to receive data from the GPS chip 2 and the sensors. The communication interface 102 is located on the left side of the microcontroller 1 and is used to communicate and transfer data with the WIFI module 3. The memory 103 is located on the right side of the microcontroller 1 and is used to store the location information and alarm records of the locator.

[0038] In a specific embodiment, the microcontroller chip 101 is the core of the GPS locator and serves as the data processing center of the GPS locator. It is responsible for receiving data from the GPS chip 2 and the sensors, processing and analyzing the received data. By obtaining the real-time data of the G-SENOR module 4, it controls the turning on and off of the GPS chip 2. It stores the data in the memory 103 for subsequent analysis, processing and query. It communicates and transfers data with the WIFI module 3 through the communication interface 102. The microcontroller chip 101 transmits the collected data information to the WIFI module 3 through the communication interface 102.

[0039] Further, the WIFI module 3 includes an antenna 301, a radio frequency front end 302, a WIFI communication chip 303 and an interface circuit 304. The antenna 301 is installed above the housing 8 and is used to receive and send WIFI signals.

[0040] In a specific embodiment, the antenna 301 is responsible for receiving signals from a wireless router or other wireless devices, and at the same time transmitting the data information received from the communication interface 102 to achieve wireless communication with other devices. When the vehicle is in motion, WIFI SCAN is enabled to scan a fixed WIFI MAC address, which is marked as the owner's WIFI.

When all of the following conditions are met simultaneously:

[0041] It is detected that the GPS locator enters the electronic fence of home;

[0042] According to the G-SENSOR sensor, the vehicle has stayed for more than 1 hour and the owner's WIFI is continuously scanned;

[0043] (3) The temperature is detected once every 10 seconds. If it does not decrease, it is judged that the vehicle has entered the indoor area.

[0044] An alarm message is sent to the platform, or an SMS alarm can also be sent to achieve the alarm for the vehicle entering the indoor area. When it is simultaneously detected that the GPS locator enters the electronic fence of home and the owner's WIFI is continuously scanned, the GPS signal becomes weak but can still be located, and the temperature will become lower after the vehicle stops moving, it is judged that the vehicle has entered the overhead floor, and an alarm message is sent to the platform to achieve the alarm for the vehicle entering the overhead floor.

[0045] Furthermore, the G-SENOR module 4 includes a piezoelectric crystal 401, a signal conditioner 402, and a vibration sensing chip 403.

The vibration sensing chip 403 is used to output the corresponding vibration signal to achieve starting and stopping the GPS. The output end of the piezoelectric crystal 401 is connected to the input end of the signal conditioner 402, and the output end of the signal conditioner 402 is connected to the input end of the vibration sensing chip 403.

[0046] In a specific embodiment, the quartz crystal material used for the piezoelectric crystal 401 is a non-centrosymmetric crystal. When subjected to external force or mechanical pressure, its crystal structure will undergo a slight distortion and deformation, causing the separation of positive and negative charges inside the crystal and forming an electric potential difference, enabling high-sensitivity measurement and detection. The signal conditioner 402 converts the vibration signal into an electrical signal in real time and transmits it to the vibration sensing chip 403, and the vibration sensing chip 403 transmits the corresponding vibration signal to the microcontroller 1. When the G-SENOR module 4 detects vibration, the GPS chip 2 is turned on for positioning. When the G-SENOR module 4 does not detect vibration, the GPS chip 2 is turned off, reducing the power consumption of the GPS locator. According to the G-SENOR module 4, an overweight state can be detected. When the GPS locator enters the electronic fence of the home, the altitude of the GPS increases from positioning to non-positioning, the air pressure becomes smaller, and the G-SENSOR detects overweight at the same time, it is determined that the vehicle has entered the floor, and an alarm message is sent to the platform to realize the alarm for the vehicle entering the floor.

[0047] Further, the thermometer sensor 5 includes a thermistor 501, a thermocouple 502, and a temperature sensing chip 503.

It can quickly and accurately convert the ambient temperature into an electrical signal, which is the basis for realizing temperature monitoring and control; the thermocouple 502 is another important component, made of a special iron-aluminum porcelain alloy containing iron and aluminum and added with A12O3 powder. It can directly measure the temperature of the GPS locator. Through the measured value of the thermocouple 502, the working state of the temperature sensor can be more accurately understood, thereby realizing the measurement of the ambient temperature around the GPS locator; the temperature sensing chip 503 is the core component of the entire sensor. It can convert the signal of the thermistor 501 into an electrical signal, and these electrical signals are transmitted to the microcontroller 1 to realize real-time monitoring of the temperature.

[0049] Further, the barometer 6 includes a piezoresistive chip 601, a signal amplifier 602, and a barometric pressure sensing chip 603.

The output end of the piezoresistive chip 601 is connected to the input end of the signal amplifier 602, and the output end of the signal amplifier 602 is connected to the input end of the barometric pressure sensing chip 603.

[0050] In a specific embodiment, the piezoresistive chip 601 is a key component of the barometer 6 and is made of silicon material. When this material is subjected to pressure, its resistance value will change. When the barometric pressure changes, the piezoresistive chip will be subjected to different degrees of pressure, thereby causing its resistance value to change accordingly. This change in resistance value is detected by the signal amplifier 602 and converted into a corresponding electrical signal. The signal amplifier 602 can amplify the input weak signal to improve the measurement accuracy and sensitivity. Only after being amplified can the signal be received and recognized by the barometric pressure sensing chip 603. The barometric pressure sensing chip 603 is the core component of the barometer 6 and is responsible for converting the change in resistance value generated by the piezoresistive chip into a digital signal and outputting it to the microcontroller 1 to realize the barometric pressure monitoring of the environment around the GPS locator.

[0052] In a specific embodiment, the housing body 801 closely surrounds the outside of the GPS locator, playing a role in reducing the damage to the GPS locator caused by physical impact. When the GPS locator is exposed to a harsher environment, the housing body 801 can effectively slow down the impact of external forces on it and effectively protect the safety of internal components. The gasket 802 is made of elastic material rubber and can effectively prevent moisture and dust from entering the inside of the GPS locator.
