An electric damper control system for urban rail transit

Abstract

The invention discloses a power-driven air valve control system for urban rail transit. The power-driven air valve control system comprises a mechanical valve turnover mechanism and an air valve electronic control system and is characterized in that the air valve electronic control system comprises a power-driven air valve controller, a power-driven air valve central control panel and a manual controller, wherein the power-driven air valve central control panel and the manual controller are connected to and communicate with the power-driven air valve controller through 485 buses. The power-driven air valve control system has the advantages that the power-driven air valve control system responses to signals of a long-distance switch air valve and can conveniently realize the opening and closing of air valves on the whole side; the power-driven air valve control system responses to signals of a network switch air valve and can conveniently realize the long-distance opening and closing of a single air valve; meanwhile, the controller can control the air valve of each unit in real time and has an emergency fault treatment function; and the power-driven air valve control system is safe and reliable, is convenient to use and has good application prospect.

Description

technical field [0001] The invention relates to an electric air valve control system for urban rail transit, belonging to the technical field of automatic control. Background technique [0002] With the development of the urban rail transit industry, the safety and comfort of the daily operation of the platform are becoming more and more important. The platform side of the underground station is separated from the track side by full-height screen doors and their upper dampers. Due to the linkage between the full-height screen door system and the train system, the timeliness of the switch is limited, so the air valve becomes an important space interface area on the platform side and the track side. When the damper is closed, the platform side is in the energy-saving mode, and when the damper is opened, the platform side is in the ventilation and smoke exhaust mode. [0003] At present, the upper part of the vast majority of screen doors in China adopts a fixed and open damp...

AI Technical Summary

Problems solved by technology

[0003] At present, the upper part of most domestic screen doors adopts fixed and open air valves, which can only play the role of ventilation and smoke exhaust, and cannot meet the requirements of energy saving.

Some cities in the north adopt a manually controlled damper structure, and the opening and closing of the dampers are controlled one by one by manpower. This structure can realize the switching between energy saving and ventilation and smoke exhaust modes, but it is time-consuming and laborious, and the immediacy of ventilation and smoke exhaust cannot be achieved. Meet the requirements

Various unfavorable factors lead to the fact that the damper conversion device currently used in China has not been popularized and promoted.
