[0002] Supplying water to trains is an important task in railway passenger transportation. When the train arrives at the water supply station, the station staff will fill the water tank of each car body with water to ensure the water needs of the passengers. At present, the degree of automation of water supply equipment in most railway stations and passenger car maintenance depots is still relatively low. When using traditional water supply equipment for water supply operations, it is still necessary to manually connect the water supply pipe to the water filling port of the passenger car water tank. When overflow begins, close the water supply valve, unplug the water supply hose, and the water supply operation is completed. In recent years, the number of water supply operators has continued to decrease, the number of carriages that need to be supervised per capita has increased, there is a waste of water resources, damage to the roadbed, high labor intensity, and time constraints. Under these circumstances, the following problems are becoming increasingly obvious:

[0003] First, the automation level is low, the operation efficiency is low, and the water resources are wasted seriously. The staff needs to move between the water well on the track and the water injection port of the train many times. The water supply operation is cumbersome and inefficient. In addition, due to limited vision and heavy workload, the water supply valve cannot be closed in time after the water tank of the passenger car is full of water, resulting in serious waste of water resources.

During the water supply operation, data information such as water volume and water pressure, operation status, abnormal faults, etc. cannot be recorded and remotely monitored, and the operation status cannot be traced and analyzed. Third, there are management loopholes and safety risks. The operation process has not formed a safe multi-level cascade control. The station cannot fully control the water supply operation process. Sometimes there is even a dangerous situation of driving with a pipe, which causes serious driving safety accidents. Based on the above problems, in order to adapt to the rapid development of railways and the development trend of intelligent railway transportation equipment, how to improve the automation level and informatization level of water supply operations, ensure safe and efficient water supply operations for passenger cars, and ensure the safety of operators and equipment are all problems that need to be solved urgently.

The push rod 303 is set to slide back and forth, and the lower end of the push rod 303 passes through the bottom of the connecting pipe 301 downwardly to the lower side of the fixed base 300, and a guide cylinder 303a is vertically and concentrically set in the connecting pipe 301. The lower end of the push rod 303 is fixed to the bottom of the connecting pipe 301, and the push rod 303 passes through the guide cylinder 303a. The guide cylinder 303a is used to support and guide the push rod 303 so that it does not deform or shake when the push rod 303 moves. The upper end height of the guide cylinder 303a is lower than the height of the connection position between the water inlet joint pipe 302 and the connecting pipe 301; the upper end of the push rod 303 extends upward to the lower part of the mouth of the connecting pipe 301, and a push head 305 is set at the top of the push rod 303. It is arranged on the driving box 306, and the posture sensor adopts a low-cost digital angle sensor module GY-25T. The acquisition output end of the posture sensor 304a is connected to the central controller. The driving box 306 is arranged at the bottom of the fixed base 300, and the fixed base 300 is fixed on the driving box 306. A driving motor 307 is arranged on one side of the driving box 306. The lower end of the push rod 303 passes through the fixed base 300 and the lower side of the driving box 306 in sequence downward from the bottom of the connecting pipe 301. A main gear 308, a slave gear 309 and a screw rod 310 are distributed in sequence on one side of the driving box 307 in the direction of the push rod 303. The screw rod 310 is arranged in a vertical direction and can be rotated. In the driving box 307, the slave gear 309 is arranged in the driving box 307 through the vertical rotating shaft 309a, the output shaft of the driving motor 306 vertically extends into the driving box 306 and is sleeved with the main gear 308, the driving motor 307 is electrically connected to the power module through the relay switch, the main gear 308 is meshed with the screw rod 310 through the slave gear 309, a slider 311 is threadedly sleeved on the screw rod 310 in the driving box 307, the outer wall of the screw rod 310 is threadedly connected with the inner wall of the slider 311, the outer wall of the push rod 303 is connected with the outer wall of the slider 311, and the slider 311 slides back and forth between the meshing position of the slave gear 309 and the screw rod 310 and the bottom of the driving box 307;The outlet end of the water supply pipe 3 is connected to the water inlet joint pipe 302. Before the water supply pipe 2 is used to supply water to the train water tank 1, the water outlet sleeve 304 on the connecting pipe 301 is first sleeved on the water inlet end (front end) of the water supply pipe 2, so that the water inlet end (front end) of the water supply pipe 2 is inserted into the water outlet sleeve 304. The posture sensor 304a detects the overall state of the automatic pipe removal component 30, and water is supplied to the water supply pipe 2 through the water supply pipe 3 and enters the train water tank 1. When the water is fully supplied to the train water tank 1, the water supply pump on the water supply pipe 11 stops supplying water, and the solenoid valve 201 is closed to stop supplying water. The central controller sends a pipe removal instruction to the drive motor 307, so that the drive motor 307 rotates and drives the main gear 308 to rotate. The main gear 308 is driven by the slave gear The wheel 309 drives the screw rod 310 to rotate. At this time, the slider 311 threaded on the screw rod 310 will move upward along the screw rod 310. When the slider 311 moves upward, it drives the push rod 303 and the push head 305 to move upward. The push head 305 pushes the end of the water pipe 2. Due to the reverse force, the water outlet sleeve 304 falls off from the outer wall of the water pipe 2. After the water outlet sleeve 304 is separated from the water pipe 2, the entire water delivery detection component 20 and the central controller and posture sensor arranged on the driving box 306 are separated from the water pipe 2, and the current connection state thereof changes. When the pipe removal stroke is completed, the posture sensor 304a detects whether the entire automatic pipe removal component 30 has undergone a significant change. If a significant change occurs, it can be determined that the pipe removal is successful. On the contrary, after the push rod 303 moves to the limit position, the posture detected by the posture sensor 304a has not changed significantly, indicating that the pipe is abnormal, and the pipe fault alarm information will be sent to prompt the staff to handle it. When an abnormal situation occurs, the handheld remote control on site and the host computer (server) of the monitoring center will issue an alarm prompt. ;

The water pipe return detection module 5 of the intelligent water supply management and control system automatically detects the water supply pipes 3 on both sides of the track and puts them back to the support notch 501 position of the water pipe placement support block 500. The RFID identifier 503 senses the identification tag (using PCB2510 tag) set on the water supply pipe 3, so as to determine whether all the water supply pipes 3 are returned to their positions, and sends the identification information to the host computer (the server of the monitoring center) through the second wireless communication module 502 to ensure the safety and integrity of the water supply operation process.

When water is being supplied, the water supply indicator light 504 lights up to display the working status of each water supply well, which is convenient for on-site workers to check and confirm when going up and down the track. After the operation is completed and all water supply equipment is returned to its position, all water supply indicator lights 504 go out.At the same time, the return status is transmitted back to the host computer (the server of the monitoring center) in real time. If any abnormal situation occurs, the station manager can timely control the relevant situation. After the water supply operation is completed through the water pipe return detection module, the water supply pipe of each water well must be returned to the designated position as required to ensure the cleanliness of the water supply joint and facilitate the next operation. The water pipe return detection module is installed on both sides of the train track. It can provide auxiliary lighting during operation. After the operation is completed, it monitors whether all water pipes on both sides of the track are fully returned to their positions, which is convenient for operators to check and confirm on and off the track. Platform staff can also easily grasp the water supply status of the train.
