Abstract

The invention relates to a laser detection and control system for barriers between a shield door of a metro platform and a train door, comprising a monitoring unit, a control unit and an alarm unit, wherein, the controller comprises a CPU module, a liquid crystal terminal, a signal isolator, buttons and a safety relay; generating lasers are respectively installed on a front bracket, and a laser receiver or a laser reflection plate is installed on a rear bracket corresponding to the front bracket; the control ends of the generating lasers are connected with the output end of the controller, and the output end of the laser receiver is connected with the input end of the controller; the corresponding output end of the controller is correspondingly connected with the control input end of the shield door; and the corresponding output end of the controller is connected with a buzzer and a caution light of the platform. The laser detection and control system realizes the intelligent operation of judging the existence of barriers between the shield door of the metro platform and the train door, has the advantages of compact integral structure, reasonable cost, easy and convenient installation, simple and intelligent operation, stable and reliable performance, higher practicability and favorable development prospect, and is applicable to metro platform.

Description

technical field [0001] The invention relates to a monitoring and control system, in particular to a laser obstacle monitoring and control system for detecting whether there is an obstacle between a screen door of a subway platform and a train door, and providing an accurate signal for safe departure of a train. Background technique [0002] As an important transportation facility in modern cities, subway has become the main development direction of public transportation in big cities due to its advantages of fast, punctual, convenient and comfortable. For safety, most of present subway platforms are provided with a screen door, that is, a barrier with a door that is convenient for passengers to ride. [0003] Installing the screen door on the subway platform is a necessary facility in the development of subway construction. The screen door isolates the platform from the train operation area, and automatically controls the opening and closing of the door. It can not only prov...
