Control system for shielding barrier and safety gate of rail transit platform

Abstract

The invention relates to a control system for a shielding barrier and a safety gate of a rail transit platform, which is connected with field gate equipment via electric signals and comprises a data acquisition unit, a central control unit and a monitoring unit. The data acquisition unit, the central control unit and the monitoring unit are connected sequentially via electric signals; the data acquisition unit is connected with the field gate equipment via electric signals; the data acquisition unit acquires data of the field gate equipment, transmits the data to the central control unit, and receives commands of the central control unit to control and set the field gate equipment; and the central control unit receives the data of the field gate equipment, transmits the data to the monitoring unit and transmits control commands issued by the monitoring unit to the field gate equipment. A common programmable controller in the present market is technically innovated, process requirements are met, various control functions of the shielding barrier and the safety gate are realized, technical bottlenecks of the programmable logic controller applied to the shielding barrier and the safety gate are broken through, and an industrial control product can be really used as a control core component on the shielding barrier and the safety gate.

Description

technical field [0001] The invention relates to automatic control, in particular to a safety door control system for rail transit platforms equipped with shielded doors. Background technique [0002] The control system of shielded doors and safety doors includes main control equipment such as door body control DCU, platform terminal control panel PSL and station central control panel PSC. The independent development of the manufacturer reduces a lot of costs, but at the same time, the reliability of the system is generally not high, the compatibility of the equipment is very poor, and the scalability of the system is greatly restricted. Contents of the invention [0003] The object of the present invention is to provide a safety door control system with screen doors with reliable operation in order to overcome the above-mentioned defects in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a rail ...
