[0019] Further, the magnetic positioning device is a positioning magnetic steel 5.

[0020] Further, the magnetic positioning device is arranged on the sleeper inside the track at the washing garage end 2 and the washing garage end 3 respectively.

[0021] Further, the infrared opposite shooting device is an infrared opposite shooting sensor 6.

[0022] Further, the infrared opposite shooting device is arranged on both sides of the track at the washing garage end 2 and the washing garage end 3 respectively.

[0023] Further, the washing indication signal device 8 comprises three kinds of signal indication lamps, which are "red light", "yellow light" and "green light" respectively, which represent three states of washing standby, washing preparation and washing permission respectively.

[0024] The automatic interlocking device 4 is composed of a PLC programmable controller installed in the control box, an HMI man-machine control interface 42, a DC 24V switching power supply 43, an intermediate relay 44, a wiring terminal 45 and a control circuit.

[0025] The working principle of the automatic interlocking device of the metro train cleaning garage door is that the magnetic positioning equipment installed on the sleepers in the track at both ends of the car washing garage area 1 detects the running position state of the train. When the wheel set passes through the magnetic positioning equipment, an electrical signal is generated by cutting the magnetic induction lines during the running of the wheel set, and the signal is transmitted to the automatic interlocking PLC 41 through the signal cable laid at both ends of the car washing garage area 1. The infrared transmitting and receiving equipment is installed on both sides of the track in the garage area, each set consisting of an infrared transmitter and a receiver, which is used to detect the running speed of the train. When the car washing speed exceeds the set speed, the existing control system of the car washer prompts the driver to reduce the speed. At the same time, the equipment also has the function of detecting the running state of the train, which assists the magnetic positioning equipment in detecting the position of the train, forming a redundant detection protection for the position of the train. The photoelectric sensor can detect the opening or closing state of the garage door on both sides of the garage area. When the train reaches or leaves the specified position, the magnetic positioning equipment on both sides of the garage area transmits the opening or closing signal to the automatic interlocking PLC 41. The automatic interlocking PLC 41 receiving the signal outputs the opening or closing signal to control the opening and closing of the garage door drive device. After the garage door is completely opened or closed, the photoelectric sensor is triggered, and the position signal is fed back to the automatic interlocking PLC 41 again.

[0026] The automatic control system PLC 9 of the car washing machine communicates with the automatic interlocking PLC 41 in real time, and according to the train position and garage door position signals fed back by the automatic interlocking PLC 41, the garage door at both ends of the car washing garage is opened or closed manually, and the car washing machine is automatically controlled to complete the car washing operation.

[0027] The car washing indication signal device 8 is provided with three signal indicator lights, namely "red light", "yellow light" and "green light", which respectively represent the three states of car washing standby, car washing preparation and car washing permission. When the train reaches the position of the magnetic positioning equipment in the garage area, the car washing indication signal device 8 displays "red light", the automatic interlocking PLC 41 controls the garage door opening mechanism at the entrance of the garage area to open the garage door, and the photoelectric sensor detects the garage door to position signal and feeds it back to the automatic interlocking PLC 41. At this time, the car washing indication signal device 8 displays "yellow light", and the automatic control system PLC of the car washing machine starts the brush group device, the spraying device, the blowing device, the water circulation and air path device, and the whole starting time is about 5 minutes. After each system device is started, the car washing indication signal device 8 displays "green light", and the driver pulls the train to complete the car washing operation.

[0028] The car washing machine garage door automatic interlocking control equipment 4 detects the working state of the magnetic positioning equipment, the infrared transmitting and receiving equipment and the garage door opening / closing state (position) photoelectric sensor, and when the car driven by the car washing machine leaves the garage end magnetic positioning equipment and the infrared transmitting and receiving equipment detection point after completing the car washing operation, the garage doors at both ends of the garage are automatically closed, and when the garage door opening / closing state (position) photoelectric sensor detects that the garage door is normally closed, the car washing machine control system automatically stands by, and the car washing indication signal equipment 8 displays a red light, and when the garage door is not normally closed or the car washing machine control system does not normally stand by, the car washing indication signal equipment 8 simultaneously displays red, yellow and green indication lights.

[0029] The car washing machine garage door automatic interlocking control equipment 4 has the function of forcibly switching the manual opening / closing of the garage doors at both ends of the garage, and by selecting "forced manual" or "automatic control" through the HMI man-machine control interface 42 embedded in the control box, the "forced manual" can be used for the maintenance of the garage door door drive mechanism during the daily maintenance operation of the garage door.

[0030] The operation steps of the utility model are as follows:

[0031] The train driver drives the train to the magnetic positioning equipment at the garage end of the car washing garage area 1, at this time the car washing indication signal equipment 8 displays a red light, the garage doors at both ends of the car washing garage area 1 are slowly opened, when the garage doors at both sides of the garage area are completed to be opened, the car washing indication signal equipment 8 displays a yellow light, and the driver drives the train into the car washing garage area 1 to perform the car washing operation after waiting for about 5 minutes.

[0032] When the last car carriage leaves the magnetic positioning equipment installation position at the exit of the car washing garage area 1, the garage doors at both ends of the garage area are slowly closed, when the garage doors at both sides of the garage area are completed to be closed, the car washing indication signal equipment 8 displays a yellow light, and after about 5 minutes, the car washing machine system is completed to be reset, the car washing indication signal equipment 8 displays a red light, at this time the car washing machine enters the standby state, and the car washing operation is completed.

[0033] The above is only the preferred embodiment of the utility model, the protection scope of the utility model is not only limited to the above-mentioned embodiment, and the technical scheme under the idea of the utility model is also the protection scope of the utility model. It should be pointed out that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the utility model are also regarded as the protection scope of the utility model.
