[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the scope of protection of this utility model.

[0022] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A control module air circuit board for cleaning urban rail treads includes an upper cover 1, a middle layer plate 2 and a lower cover 3. The middle layer plate 2 is located between the upper cover 1 and the lower cover 3. The upper cover 1, the middle layer plate 2 and the lower cover 3 are connected in series and detachably arranged. An embedded window 5 is opened in the middle area of ​​the middle layer plate 2, and an air duct plate 4 is embedded in the embedded window 5.

[0023] The air duct plate 4 is provided with an air inlet chamber 405, a pressure reducing valve receiving chamber 401, a solenoid valve receiving chamber 402 and an air outlet chamber 404. The air duct plate 4 is provided with a first channel 406 for connecting the air outlet chamber 404 and the solenoid valve receiving chamber 402, a second channel 407 for connecting the solenoid valve receiving chamber 402 and the pressure reducing valve receiving chamber 401, and a third channel 408 for connecting the pressure reducing valve receiving chamber 401 and the air inlet chamber 405.

[0024] The upper cover 1 has a pressure reducing valve hole 102 that matches the pressure reducing valve receiving cavity 401, a solenoid valve hole 101 that matches the solenoid valve receiving cavity 402, an air outlet hole 105 that matches the air outlet cavity 404, and an air inlet hole 103 that matches the air inlet cavity 405. These holes allow a pressure reducing valve to be installed in the pressure reducing valve receiving cavity 401 and a solenoid valve to be installed in the solenoid valve receiving cavity 402. An air inlet connector and an air outlet connector are installed at the air inlet hole 103 and the air outlet hole 105, respectively. The solenoid valve is used to open and close the connection between the first channel 406 and the second channel 407. The pressure reducing valve regulates the gas flow in the second channel 407 as it enters the third channel 408. The pressure reducing valve regulates the high-pressure compressed air in the main air duct to this range to ensure the stable and reliable operation of the tread cleaner. The solenoid valve receives control signals from the train control system. When the train control system issues an instruction to apply or release the tread cleaner, the solenoid valve can control the opening and closing of the air circuit according to the instruction. When the air duct plate 4 has problems such as cracking, only the air duct plate 4 needs to be replaced, which greatly reduces production costs. This design achieves independent replacement of the air duct plate through a modular and detachable structure, reducing maintenance costs. The reasonable channel layout ensures stable air pressure transmission. With the corresponding openings on the top cover, the components can be accurately installed, meeting the high-efficiency control requirements of the cleaning system. Furthermore, the flow rate can be adjusted by replacing the air duct plate with different flow rates, i.e., different internal channel flow rates.

[0025] In this embodiment, a pressure detection chamber 403 is formed on the air duct plate 4, and the first channel 406 is connected in series with the pressure detection chamber 403. A detection hole 104, matching the pressure detection chamber 403, is formed on the upper cover 1. A pressure switch can be installed in the detection hole 104. The pressure switch is located downstream of the solenoid valve, and its interface is connected to the air duct channel inside the air duct plate body. The pressure switch detects the pressure in the air duct in real time and feeds back the pressure signal to the train control system. When the tread cleaner is applied, the pressure in the air duct increases. When the pressure switch detects that the pressure has reached the set applied pressure value, it sends a signal to the train control system that the tread cleaner has been applied. When the tread cleaner is released, the pressure in the air duct decreases. When the pressure switch detects that the pressure has dropped to the set release pressure value, it sends a signal to the train control system that the tread cleaner has been released. Based on the signal fed back by the pressure switch, the train control system can monitor the working status of the tread cleaner in real time to ensure its normal operation.

[0026] In this embodiment, a rubber layer is provided on the contact surface between the air duct plate 4 and the upper cover 1 and the lower cover 3. The rubber layer plays a sealing role to prevent gas leakage.

[0027] In this embodiment, a positioning protrusion 6 is provided on the mating surface of the air passage plate 4, the upper cover 1, and the lower cover 3, and the positioning protrusion 6 is matched with the groove 7 opened on the upper cover 1 and the lower cover 3.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
