[0018] Master control 1; upper spray system 2; upper solenoid valve 21; upper booster pump 22; upper water spray pipe 33; lower spray system 3; lower solenoid valve 31; lower booster pump 32; lower water spray pipe 33; temperature sensor 4; camera 8; charging platform 9. DETAILED DESCRIPTION

[0019] The specific implementation of the present invention will be described below with reference to the accompanying drawings.

[0020] As a specific embodiment, the charging parking platform fire protection system control method of the embodiment of the present invention uses the charging parking platform fire protection system.

[0021] The charging parking platform fire protection system includes a master control 1, an upper spray system 2, a lower spray system 3, a charging platform 9, and a temperature sensor 4 arranged on the charging platform 9. The master control 1 is a conventional PLC, circuit board, etc. in the prior art for realizing electrical signal input, output and processing.

[0022] The upper spray system 2 includes an upper water spray pipe 33 and an upper booster pump 22 and an upper water spray pipe 33 arranged on the upper water spray pipe 33. The upper water spray pipe 33 is located above the charging platform 9 and faces downward; the lower spray system 3 includes a lower water spray pipe 33 and a lower solenoid valve 31 and a lower booster pump 32 arranged on the lower water spray pipe 33. The lower water spray pipe 33 is arranged on the charging platform 9 and faces upward.

[0023] The upper solenoid valve 21 , the lower solenoid valve 31 , the upper boost pump 22 , the lower boost pump 32 , and the temperature sensor 4 are electrically connected to the master controller 1 , respectively.

[0024] The charging parking station fire protection system control method of the embodiment of the present invention comprises the following steps:

[0025] When the temperature sensor 4 detects that the vehicle battery temperature is abnormal, the temperature sensor 4 feeds back the abnormal information to the master control 1; for example, the temperature sensor 4 detects that the vehicle battery temperature is higher than a preset threshold value and determines it as abnormal.

[0026] The master control 1 issues a command to open the lower spray system 3 to spray water mist on the bottom of the vehicle to cool it down; water mist refers to spraying smaller water particles when the water pressure is low, while the later-mentioned spraying refers to spraying larger water particles when the water pressure is high; it is easy to understand that the total water volume of spraying is greater than the total water volume of spraying water mist. It is an existing technology to realize spraying water mist and spraying with the same nozzle, which will not be repeated here.

[0027] When the temperature sensor 4 detects that the vehicle temperature is still abnormal after the lower spray system 3 is turned on to spray water on the bottom of the vehicle to cool down the set time, the master control 1 issues a command to open the upper solenoid valve 21, the upper boost pump 22, the lower solenoid valve 31 and the lower boost pump 32, so that the upper spray system 2 and the lower spray system 3 spray the top and bottom of the vehicle respectively, which can prevent the vehicle from spontaneously igniting and exploding due to battery temperature increase or reduce the risk.

[0028] When the temperature sensor 4 detects that the vehicle temperature has returned to normal after the lower spray system 3 is turned on to spray water on the bottom of the vehicle for a set time to cool it down, it means that the abnormal factors have been eliminated or the fire protection has taken effect. Then the master control 1 issues a command to control the lower solenoid valve 31 to close, and the lower spray system 3 is closed, which can reduce the probability of misjudgment and save water.

[0029] It can be seen from the above that the charging parking station fire protection system control method of the embodiment of the present invention can prevent the vehicle from spontaneously igniting and exploding due to battery temperature rise or reduce the risk, and can reduce the probability of misjudgment and save water.

[0030] As one of the specific implementations, the charging parking platform fire protection system further includes a camera 8 electrically connected to the master control 1, and the camera 8 faces the charging platform 9 to record the vehicle information entering the platform, realize the recording of the visual information of the charging process and the equipment processing information (water spraying process) of the occurrence.

[0031] As one of the specific implementation methods, the charging parking platform fire protection system includes an Internet module (not shown in the accompanying drawings) electrically connected to the main control 1. When the temperature sensor 4 detects that the vehicle battery temperature is abnormal, the abnormal information is fed back to the main control 1; the main control 1 sends a notification message through the Internet module to notify at least one of the vehicle owner, the operation platform, the relevant person in charge and the unit.

[0032] As one of the specific implementations, the charging parking station fire protection system further includes a power control module (not shown in the drawings), and when the temperature sensor 4 detects that the vehicle battery temperature is abnormal, the master control 1 issues an instruction to shut down the power control module, which can further reduce the probability of misjudgment.

[0034] As used herein, the terms a, an, etc. do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced object.

[0035] Terms indicating orientation or position as used in the present invention, such as top, bottom, side, longitudinal, lateral, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.
