[0019] Pre-wetting operation of the front of the vehicle: After the high-speed train finishes its operation, it needs to be driven to the depot for cleaning. Workers first turn on the power and water supply lines in the depot. At this time, the pre-cleaning component 1, the high-speed train cleaning component 2, and the drying component 3 are activated, and the equipment program starts. The program first uses two sets of 3D laser scanning devices to quickly identify the high-speed train model and compares it with the set values. The program sets the high-speed train model to A1, A2, and A3, which can be adjusted according to specific needs. The program also sets the metering values ​​of the two metering pumps to B1, B2, and B3, with B1 being the minimum and B3 the maximum, which can be adjusted according to specific needs. When the program identifies the high-speed train model as A1 using the two sets of 3D laser scanning devices, it controls the two metering pumps to start, setting the metering value to B1. Two air compressors also start. The program uses the first camera 211 to detect the high-speed train's position and uses AI visual recognition technology to control precise spraying. 13. First, compressed air is pumped into the first delivery pipe 131. At this time, the compressed air sprays clean water outward from the first pre-cooling spray frame 132, and then transports the clean water to the right along the first delivery pipe 131. Then, the first metering pump 142 draws the cleaning agent in the first agent storage tank 14 into the second delivery pipe 141 in an amount B1, and then pumps it into the first delivery pipe 131. At this time, the clean water and cleaning agent mix and are sprayed outward from the first agent spray frame 133. The air compressor 15 first pumps compressed air into the third delivery pipe 151. At this time, the compressed air sprays clean water outward from the second pre-cooling spray frame 152, and then transports the clean water to the right along the third delivery pipe 151. Then, the second metering pump 162 draws the cleaning agent in the second agent storage tank 16 into the fourth delivery pipe 161 in the amount of B1, and then pumps it into the third delivery pipe 151. At this time, the clean water and cleaning agent are mixed and sprayed outward from the second agent spray frame 153. When the equipment program identifies the train model as A2 using two sets of 3D laser scanning devices, it controls the metering values ​​of the two metering pumps to be adjusted to B2. The two air compressors start, and the equipment program detects the train's position using the first camera 211 and controls precise spraying using AI visual recognition technology. The first air compressor 13 first pumps compressed air into the first delivery pipe 131. At this time, the compressed air sprays clean water outwards from the first pre-cooling spray frame 132, then transports the clean water to the right along the first delivery pipe 131.

[0020] Carriage cleaning operation: After completing the above operations, the equipment program controls the carriage cleaning operation. The equipment program detects the position of the train through the first camera 211. When the train moves to the train cleaning component 2, the equipment program controls the carriage cleaning operation. The equipment program sets the extension values ​​of the two sets of electric hydraulic telescopic rods to C1, C2, and C3, where C1 is the minimum value and C3 is the maximum value. These values ​​can be adjusted according to specific needs. The speed of the two sets of motors is D1, which can also be adjusted according to specific needs. When the equipment program detects that the train type is A1, it controls the extension value of the two sets of electric hydraulic telescopic rods to be adjusted to C1, and the two sets of motors are turned on at a speed of D1. The first electric hydraulic telescopic rod 251 extends outward and drives the second mounting base 252 to move outward. The first cleaning brush cylinder 254 on the second mounting base 252 is brought into contact with the surface of the train car. Then, the program controls the first motor 253 to rotate at a speed of D1. The first motor 253 drives the first cleaning brush cylinder 254 to rotate, which brushes the surface of the train car. The second electric hydraulic telescopic rod 263 extends outward and drives the third mounting base 26 to rotate outward along the rotating rod 261, which causes the second cleaning brush cylinder 265 to rotate outward and come into contact with the upper and lower arcs and chassis of the train car. Then, the equipment program controls the second motor 264 to rotate at a speed of D1. The second motor 264 drives the second cleaning brush cylinder 265 to rotate, which brushes the upper and lower arcs and chassis of the train car, and can also brush the car connection area. When the equipment program detects that the train model is A2, it controls the extension value of the two sets of electro-hydraulic telescopic rods to be adjusted to C2. Both motors are activated at a speed of D1. The first electro-hydraulic telescopic rod 251 extends outward, driving the second mounting base 252 to move outward, causing the first cleaning brush cylinder 254 on the second mounting base 252 to adhere to the surface of the train car. Then, the program controls the first motor 253 to rotate at a speed of D1. The first motor 253 drives the first cleaning brush cylinder 254 to rotate, thus... The surface of the train carriage is brushed. The second electric hydraulic telescopic rod 263 extends outward and drives the third mounting base 26 to rotate outward along the rotating rod 261, so that the second cleaning brush cylinder 265 rotates outward and fits against the upper and lower arcs and chassis of the train carriage. Then, the equipment program controls the second motor 264 to rotate at a speed of D1. The second motor 264 drives the second cleaning brush cylinder 265 to rotate, brushing the upper and lower arcs and chassis of the train carriage. At the same time, the carriage connection area can also be brushed. When the equipment program detects that the train model is A3, it controls the extension value of the two sets of electro-hydraulic telescopic rods to be adjusted to C3. Both motors are activated at a speed of D1. The first electro-hydraulic telescopic rod 251 extends outward, driving the second mounting base 252 to move outward, causing the first cleaning brush cylinder 254 on the second mounting base 252 to adhere to the surface of the train car. Then, the program controls the first motor 253 to rotate at a speed of D1. The first motor 253 drives the first cleaning brush cylinder 254 to rotate, thus... The surface of the train carriage is brushed. The second electric hydraulic telescopic rod 263 extends outward and drives the third mounting base 26 to rotate outward along the rotating rod 261, so that the second cleaning brush cylinder 265 rotates outward and fits against the upper and lower arcs and chassis of the train carriage. Then, the equipment program controls the second motor 264 to rotate at a speed of D1. The second motor 264 drives the second cleaning brush cylinder 265 to rotate, brushing the upper and lower arcs and chassis of the train carriage. At the same time, the carriage connection area can also be brushed. During the above operations, the equipment program controls the built-in metering pump of the cleaning water tank 22 to start. The built-in metering pump of the cleaning water tank 22 pumps the cleaning agent into the second cleaning water pipe 233, and then into the first cleaning water pipe 23. Finally, it sprays the cleaning agent from the first high-pressure spray frame 231 and the second high-pressure spray frame 232 onto the surface of the train carriage. This, together with the first cleaning brush cylinder 254, performs a brushing operation on the surface of the train carriage. At the same time, it can also rinse the chassis of the train carriage. At this time, the built-in metering pump of the cleaning water tank 22 also sprays the cleaning agent directly from the first cleaning nozzle 221 and the second cleaning nozzle 222 onto the surface of the two sets of cleaning brush cylinders, improving the brushing efficiency and enhancing the washing effect. During the above operations, the equipment program can also control the roof cleaning operation. The equipment program detects the position of the train roof through the second camera 212 and controls the operation of the robotic arm 24. The equipment program controls the robotic arm 24 to hold the wall-mounted intelligent cleaning robot 214 and place it on the train roof for cleaning. The wall-mounted intelligent cleaning robot 214 can move in the opposite direction along with the train body. It is equipped with an anti-tangling brush and a high-pressure spray system. The flexible spray and AI vision work together to ensure the cleanliness of the upper part of the train head. It is also equipped with double protection (limiting + insulating baffle) to ensure 27KV high voltage safety. After the cleaning of the top of one train car is completed, the equipment program controls the robotic arm 24 to hold the wall-mounted intelligent cleaning robot 214 and place it on the top of the next train car to repeat the above cleaning operation. While cleaning, the equipment program controls the second train cleaning component 27 to perform the above operations simultaneously; By using two sets of electric hydraulic telescopic rods, two sets of cleaning brush cylinders, and the first camera 211 in conjunction with the equipment program, the amount of brushes can be automatically adjusted based on the train model identified by two sets of three-dimensional laser scanning devices. In winter use, it can effectively remove snow and ice from the upper and lower arcs and chassis of the train body. With the cooperation of the wall-mounted intelligent cleaning robot 214, the robotic arm 24 and the equipment program, it can perform brushing operations on the top of the train carriages and can move synchronously with the train body, automatically avoiding obstacles such as pantographs and air conditioners. It is equipped with double protection (limiting + insulating baffle) to ensure the safety of 27KV high voltage. During the cleaning process, the system can perform autonomous intelligent self-checks, link multiple robots to perform contour cleaning of the train body, and follow the train for cleaning based on the required travel speed of 3~5km / h during the cleaning process. It can also stop operation in time if a problem is detected to ensure the safety of the car washing operation and the cleaning effect.

[0021] Vehicle body drying operation: After the above operations are completed, the equipment program controls the car body to perform air drying. The equipment program controls the start of two sets of water blowers. The first water blower 31 blows air into the first air pipe 311 and then blows it out from the first air drying rack 312 to the surface of the EMU car. The second water blower 33 blows air into the third air pipe 331 and then blows it out from the third air drying rack 332 to the surface of the EMU car. The first air drying rack 312 and the third air drying rack 332 can perform cold air drying on the surface of the EMU car and quickly remove water stains from the exterior of the EMU. While performing the above-mentioned cold air drying operation, the equipment program controls the start of two sets of plasma sterilization chambers. The first blower 31 can also blow air into the second air pipe 32, and after being heated and sterilized at the first plasma sterilization chamber 321, it is blown out from the second air drying rack 322 to the surface of the train car. The second blower 33 can also blow air into the fourth air pipe 34, and after being heated and sterilized at the second plasma sterilization chamber 341, it is blown out from the fourth air drying rack 342 to the surface of the train car. By using two sets of water blowers, the first drying rack 312, the third drying rack 332, and the equipment program, the surface of the train carriage can be dried with cold air first, quickly removing water stains from the train's exterior and preventing water spots from remaining on the surface. By using the second drying rack 322, the fourth drying rack 342, two sets of plasma sterilization chambers, and the equipment program, the surface of the train carriage can be dried with plasma hot air, quickly removing water stains from the train's exterior. In winter, this also prevents water stains from freezing, providing a protective effect.
