System control method for increasing the water supplying efficiency of railway carriage

Abstract

The present invention relates to a system control method for increasing the water supplying efficiency of railway carriage, and belongs to the field of automatic water supplying control of railway carriage. The technical plan is that the flowing and stopping of water are used as the control feedback signal of water supplying. The water flows when supplied into the water tank. After the water tank is filled with water, the water stops. The effective combination of on-carriage water storing system and ground water supplying system is realized through monitoring the state of water. The carriage water supplying system is composed of a water supplying control valve, a flowing detector, a backwater control valve, a control cabinet, a rubber hose, an electromagnetic fast joint, a water tank control valve, a water level meter and the water tank. The electromagnetic fast joint, the backwater control valve and the water supplying control valve are controlled uniformly under the function of control cabinet. The invention overcomes the problem of large labor intensity and no effective control of water supplying process of railway carriage caused by prior operation. The effective control of water supplying process of railway carriage is realized. The water is supplied automatically. The water is stopped automatically when the water tank is full. The water backing and breaking-off of the joint are automatic. The system control method for increasing the water supplying efficiency of railway carriage according to the invention settles the key problem existing in prior operation.

Description

technical field [0001] The invention relates to a system control method for improving the water filling efficiency of railway passenger cars, which belongs to the field of automatic water filling control of railway passenger cars. Background technique [0002] The existing passenger car water supply system is mainly operated manually. After the bus arrives at the station, the water supply staff will forcefully insert the rubber hose into the water injection port of the passenger car, and use the squeeze between the rubber hose and the water injection port to ensure that the water pipes are clean during the water supply process. If it does not fall off, the water operator will go back to the water plug well and open the valve to start watering. When the overflow pipe on the car starts to overflow, return to the water plug well to close the valve and forcefully pull out the rubber hose from the water injection port of the bus. process can end. It is time-consuming and labor-i...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of high labor intensity caused by the existing operation and the inability to effectively control the water filling process of passenger cars, the present invention proposes a system control method for improving the water filling efficiency of passenger cars, which solves the problem of the relationship between the water level signal of the water tank on the car and the ground water supply system. The signal connection problem of the bus has realized the effective control of the water supply process of the bus. Under the action of the control system, automatic water supply, automatic water full stop, automatic water return, and automatic joint drop-off have been realized, which not only improves the water supply efficiency, but also solves the problem of Key issues with existing operations
