Description

Technical Field

[0001] This invention belongs to the field of railway locomotive maintenance technology, specifically relating to an automatic water supply system for railway passenger cars and its control method. Background Technology

[0002] Currently, water supply operations for railway passenger cars mostly rely on manual operation. The operation process is as follows: staff first manually open the water pipe baffle on the side or bottom of the passenger car, then drag the water supply hose to the passenger car's water inlet and manually connect and fix it. After the water tank is full, the water inlet valve is closed, the hose is removed, and the water pipe baffle is manually closed. This method has many drawbacks: it takes a long time to fill a single bus with water, making it difficult to meet the needs of high-density train scheduling; it requires dedicated water-filling personnel at each passenger station, and the workload is heavy; at night or in bad weather, staff are prone to accidents such as bumps and slips due to obstructed vision; and it is impossible to accurately monitor the water tank level, which can easily lead to overflows or insufficient water filling. Summary of the Invention

[0003] In order to solve at least one of the above-mentioned technical problems in the prior art, the present invention provides an automatic water supply system for railway passenger cars and its control method.

[0004] This invention is implemented using the following technical solution: an automatic water supply system for railway passenger cars, comprising a water storage tank, a passenger car water tank, an automatic robotic arm, a water supply auxiliary short pipe, a camera, a baffle cylinder, and a controller; the automatic robotic arm is equipped with the water supply auxiliary short pipe and the camera, wherein the water supply auxiliary short pipe is a rigid pipe, one end of which is fixedly connected to the water outlet pipe of the water storage tank, the water outlet pipe of the water storage tank is a retractable flexible pipe, and the other end of the water supply auxiliary short pipe is used to connect to the water inlet of the passenger car water tank; the camera is used to identify the opening and closing status of the water inlet baffle and the position of the water inlet of the passenger car water tank; the water inlet baffle of the passenger car water tank is located on the side or bottom of the passenger car, and the baffle cylinder is used to control the opening and closing of the water inlet baffle; a float-type level gauge for indicating the water level is installed inside the passenger car water tank; the automatic robotic arm, the camera, and the float-type level gauge are all electrically connected to the controller.

[0005] Preferably, the automated robotic arm is slidably installed on the side wall of the platform on the side where the railway passenger car stops. Identification cards are installed on the outer wall of the passenger car at the location of each water tank of the automated robotic arm and the railway passenger car. The automated robotic arm can be positioned at the location of each water tank by using the identification cards.

[0006] Preferably, a guide rail is provided on the side wall of the platform where the railway passenger car stops, and a guide wheel is provided on the side of the automatic robotic arm near the guide rail. The guide wheel is driven by a driver installed on the automatic robotic arm, and the driver and the identification card are electrically connected to the controller.

[0007] Preferably, a ring to be identified is fitted onto the water inlet end of the bus water tank. The position of the ring to be identified does not interfere with the connection between the water supply auxiliary short pipe and the water inlet end of the bus water tank. The camera can quickly determine the position of the water inlet end of the bus water tank by identifying the position of the ring to be identified.

[0008] Preferably, the ring to be identified has a reflective coating to facilitate rapid identification by the camera in dark environments.

[0009] Preferably, a solenoid valve I is installed on the hydraulic pipeline where the baffle cylinder is located. The solenoid valve I is an electromagnetic directional valve and is electrically connected to the controller. It is used to control the extension and retraction of the baffle cylinder, thereby controlling the opening or closing of the water inlet baffle.

[0010] Preferably, a solenoid valve II is installed on the outlet pipe of the water storage tank. The solenoid valve II is electrically connected to the controller and is used to link with the float-type level gauge to control the flow of water in the outlet pipe of the water storage tank according to the water level of the bus water tank.

[0011] A second aspect of the present invention provides an automatic water supply control method for railway passenger cars, comprising the following steps: S101: After receiving the railway passenger car's arrival signal, the controller controls the driver on the automatic robotic arm to drive the guide wheel to move. Through the position identification of the identification card, the automatic robotic arm is moved to the location of the railway passenger car's water tank. S102: The camera on the automatic robotic arm identifies the opening and closing status of the water inlet baffle and sends the opening and closing status information to the controller. The controller controls the solenoid valve I to switch, the baffle cylinder retracts, and drives the water inlet baffle to open. S103: The camera identifies the ring to be identified and quickly locates the position of the water inlet of the bus water tank. The controller receives the position information and controls the automatic robotic arm to drive the water supply auxiliary pipe to be inserted into the water inlet of the bus water tank. S104: The float-type level gauge detects the liquid level information of the bus water tank. The controller controls the solenoid valve II to open based on the liquid level information until the water level is detected to meet the water level required by the bus water tank, and then controls the solenoid valve II to close. S105: The controller controls the automatic robotic arm to retract the water supply auxiliary short pipe, and at the same time controls the solenoid valve I to switch, the baffle cylinder to extend, and drives the water inlet baffle to close. S106: The controller controls the driver of the automated robotic arm, causing the automated robotic arm to move to the next water filling position.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention enables fully automated operation. By combining technologies such as automated robotic arms, visual positioning, and solenoid valve control, it automates the entire process from opening the baffle, connecting the water inlet pipe, filling the water, stopping, to resetting the equipment, without the need for manual intervention. This significantly improves operational efficiency, reducing the water filling time for a single passenger car to 3-5 minutes, thus meeting the needs of high-density train scheduling.
