Motor car top climbing operation safety door comprehensive monitoring and card control system

Abstract

The invention relates to a motor car top climbing operation safety door comprehensive monitoring and card control system. The system comprises a card control unit, a safety door control unit and a monitoring unit. According to the motor car top climbing operation safety door comprehensive monitoring and card control system, triple card control management can be performed on a top climbing operation safety door through a computer main control unit, a PLC interlocking control unit and a top climbing operation card distribution unit, the safety card control capability of the safety door is enhanced, and the motor car top climbing operation safety is ensured; the state of the safety door is comprehensively monitored through six monitoring means of power loss monitoring, illegal intrusion monitoring, emergent door opening monitoring, door lock fault monitoring, access people number monitoring and video monitoring, corresponding alarm promote messages are provided, the safety monitoring function of the safety door is enhanced, the basis is provided for related people for finding and solving problems, the related people are guided to deal with the problems in time and start to adopt emergency plans, and the field operation safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of motor car maintenance operations, in particular to a comprehensive monitoring and jamming control system for a safety door of a motor car climbing to the top. Background technique [0002] In the safety interlocking monitoring system of the motor vehicle maintenance operation, the safety door for the climbing operation is one of the components of the system, and it is also the most important checkpoint for the safety of the climbing operation. In the EMU maintenance depot, there are generally multiple safety doors for climbing operations on each track. The personnel who climb to the top must pass through the safety doors to enter the three-story operation platform to perform maintenance and repair operations on the top equipment of the EMU. Since there is a high-voltage catenary on the top of the motor car, it must be ensured that the safety door can be opened only when the catenary is powered off, and th...

Problems solved by technology

Ordinary access control systems generally only include access controllers, card readers, electromagnetic locks and other equipment. The access control functions are single, card control capabilities are weak, monitoring methods are lacking, and there are many security loopholes, which are far from meeting the safety interlocking monitoring of train maintenance operations. System security card control needs
