A control system of electric conversion device for urban rail transit

Abstract

The invention discloses an electric conversion device control system for urban rail transit. The electric conversion device control system mainly comprises an electric conversion device central control dial plate TPSC, an electric conversion device control unit PZZ, a mechanical valve blade turning mechanism, a power system and a connecting harness; and a main-control PLC, a human-computer interaction interface HMI, communication interfaces and a control line interface are arranged in the electric conversion device central control dial plate TPSC, the main-control PLC receives an external system signal converted by the communication interfaces and a feedback signal of the electric conversion device control unit PZZ and sends out a signal through the control line interface to control the electric conversion device control unit PZZ, and state information of the electric conversion device control unit PZZ is converted through the communication interfaces to be displayed on the human-computer interaction interface HMI. By the adoption of the electric conversion device control system for urban rail transit, a series of purposes including automatic switching of the function of ventilation between the platform side and the rail side and the function of energy saving, remote control and monitoring of a shutter on the upper portion of a full-height shield door, and fire prevention, smoke discharging and the like of the platform side are achieved for the prior art.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a control system of an electric conversion device for urban rail transit. Background technique [0002] In recent years, with the rapid development of the urban rail transit industry, people are increasingly paying attention to the comfort and energy saving of the platform while the safety requirements for urban rail transit operations are increasing. For underground stations, the platform side and the track side are mainly separated by full-height screen doors and upper shutters. At present, the upper shutters of most of the screen doors in China are fixed. This method can only play the role of ventilation and decompression, and cannot achieve the function of energy saving and fire prevention. There are also some cities, mostly in the north, which adopt the structure of manually controlled upper shutters, and completely rely on manpower to control the open...
