[0044] Example two

[0045] Based on example one, as shown in Figure 1 and Figure 2 , the working mode of the device is:

[0046] (1) Standby state: when the device is in an unstarted state, the conductive adhesive tape 2 remains disconnected and does not consume electricity. The waterproof light strip 3 is turned off, and the temperature measuring thermistor 7 and the temperature measuring probe 8 are in standby state.

[0047] (2) Start and temperature measurement: when the electric vehicle is parked in the parking space 13, the conductive adhesive tape 2 is pressed by the wheel to close the circuit and send a working signal to the main control device. After receiving the signal, the main control device starts the device into working state. At this time, the temperature measuring probe 8 starts to perform infrared temperature measurement on the upper battery pack on fire, and the temperature measuring thermistor 7 measures the space temperature. The main control device analyzes and processes the received temperature signal.

[0048] (3) Fire extinguishing and temperature reduction: when the temperature exceeds the preset safety threshold, the main control device judges that there is a fire risk and sends a control signal to the water inlet electromagnetic valve 9 and the electric control nozzle 6. The water inlet electromagnetic valve 9 quickly opens to allow water flow to enter the water spraying frame 5 through the water inlet pipe 11. At the same time, the electric control nozzle 6 also opens after receiving the signal to uniformly spray water to the bottom of the electric vehicle for fire extinguishing and temperature reduction. At this time, the waterproof light strip 3 may be turned on as a warning.

[0049] (4)Drainage and cleaning: after the fire is extinguished, the main control device sends a signal to the drain electromagnetic valve 10, the drain electromagnetic valve opens, and the accumulated water is discharged through the drain pipe 12 to avoid secondary damage caused by accumulated water. At the same time, the main control device records the fire extinguishing process and restores the standby state.

[0050] Example three

[0051] Based on example one, as shown in Figure 1 and Figure 2 , the automatic temperature measurement, fire extinguishing and cooling device for electric vehicle parking based on temperature monitoring and intelligent control principle realizes early warning and rapid response to electric vehicle fire. The specific working principle is as follows:

[0052] (1) Temperature monitoring: the device sets temperature measurement probe 8 and temperature measurement thermistor 7 on the parking space. The temperature measurement probe 8 uses thermocouple infrared temperature measurement technology to non-contact measure the temperature of the bottom battery pack of the electric vehicle, avoiding the measurement error caused by contact with water or impurities in the traditional temperature measurement method. The temperature measurement thermistor 7 is used to monitor the temperature of the environment around the parking space. The combination of the two can more accurately judge whether the electric vehicle is at risk of fire.

[0053] (2) Signal transmission and processing: the temperature measurement probe 8 and the temperature measurement thermistor 7 convert the temperature signal into an electrical signal, which is transmitted to the main control device through the wire. The CPU main control chip built-in the main control device analyzes and processes the received temperature signal to determine whether it reaches the preset fire warning threshold.

[0054] (3) Fire extinguishing and cooling response: when the temperature signal exceeds the warning threshold, the main control device determines that there is a fire risk and immediately sends a control signal to the water inlet electromagnetic valve 9 and the electric control nozzle 6. The water inlet electromagnetic valve 9 is opened to allow the water flow from the external water source to enter the water spraying frame 5 through the water inlet pipe 11, and to be evenly sprayed to the bottom of the electric vehicle through the electric control nozzle 6, realizing fire extinguishing and cooling. At the same time, the main control device can control the waterproof light strip 3 to light up, providing guidance for the vehicle on fire, and ensuring that the fire extinguishing water flow can accurately cover the fire area.

[0055] (4) Drainage and reset: after the fire extinguishing and cooling process is completed, the main control device sends a signal to the drain electromagnetic valve 10, the drain electromagnetic valve opens, and the accumulated water is discharged through the drain pipe 12 to avoid secondary damage caused by accumulated water. The device restores the standby state and waits for the next start signal.

Embed waterproof light strips 3 on both sides of the parking space 13 and connect them with the main control device through wires. Fix the temperature measuring thermistor 7 and the temperature measuring probe 8 around the water spraying plate 4 and above the parking space 13 respectively to ensure accurate temperature measurement. Connect the water inlet electromagnetic valve 9 and the drainage electromagnetic valve 10 with the water spraying frame 5 through pipelines and connect them with the water supply source and the drainage system.

[0059] (2) Software setting: write control programs on the PCB board with CPU main control chips in the main control device, set parameters such as fire warning threshold and fire extinguishing and temperature reduction response strategy. Configure a wireless signal transceiver unit to remotely monitor and debug the device state.

[0060] (3) Function test: after the device is installed, perform function test to ensure that the conductive adhesive strips 2, the waterproof light strips 3, the electrically controlled nozzles 6, the temperature measuring thermistor 7, the temperature measuring probe 8, the water inlet electromagnetic valve 9 and the drainage electromagnetic valve 10 and other components are working normally. Simulate a fire scene to test the fire extinguishing and temperature reduction effect and the drainage function of the device.
