地铁站台超长距离光电保护系统的研制

Development of an Ultra-Long Distance Optoeletronic Protective System of a Subway Platform

地铁站台超长保护距离光电保护系统采用可靠安全的激光脉冲,形成长200 m、宽1.7 m、间距24 mm的扫描光幕,系统具有完善的自检功能和良好的抗干扰能力,可有效地监控列车启动时车门处乘客的状态,避免列车启动时对乘客造成挤压伤害,从而保护乘客的人身安全。

A ultra-long distance optoelectronic protective system that is based on the need for protecting the safety of passengers on a subway platform is designed, which has such positives as an ultra-long protective light curtain, better self checking functionality, good interference suppress/on capability, and high securry and reliability clue to the application of laser technology. This system can effectively avoid causing the passengers to be clamped when the train starts and the possible resulted damages to the passengers getting on or off train will take place, so it can protect the security of passengers.
