Subway train pantograph control method based on train network system

Abstract

The invention relates to a subway train pantograph control method based on a train network system. A pantograph hoisting instruction can be sent through a pantograph control switch on a driver display or a driver platform, the instruction is transmitted to a central control unit of the train network system through a driver display unit (when an operation is carried out on the driver display unit) or a remote input and output module (when the operation is carried out at the driver platform), the central control unit performs logic diagnosis by combining with states of relative system equipment and the like, and then sends a corresponding control instruction to a dragging assistant system and a pantograph control system, and then hoisting of the pantograph is controlled. By the subway train pantograph control method based on the train network system, a network system software is used for controlling the hoisting of the pantograph, manufacturing cost of a train is saved, and a trouble brought about by wiring is reduced. The subway train pantograph control method based on the train network system has the characteristics of high technical reliability, low equipment cost and simpleness in implementation and the like.

Description

technical field [0001] The invention relates to a method for controlling a pantograph of a subway train based on a train network system. Background technique [0002] Most of the current subway trains use electric trains. A typical 6-section subway train is composed of 4 moving cars and two trailers. A 6-section subway train is usually divided into two units (three cars per unit) ), there is a set of pantographs on the motor car in the middle of each unit, which is used for high-voltage power supply of the train. At present, the pantograph lifting control system on the subway train uses the train hard wire that runs through the whole train. Using the train hard wire will increase the manufacturing cost of the train, and it will also cause troubles in wiring and increase the weight of the train. With the rapid development of the network communication field and the continuous maturity of the train control and monitoring system, it is obvious that using the train network syste...
