安全防护装置在屏蔽门系统中的应用

On the Application of Safe Protection Device in Platform Screen Door System

屏蔽门和列车之间的间隙一直是系统设计中不安全的一个隐患。从设计的角度介绍了物理、红外、激光等三种安全防护装置的设置方案。从漏报或误报率、抗干扰性、对人的伤害、使用环境、与屏蔽门的接口、系统投资等方面对三种方案进行了比较。激光方式较物理、红外方式虽成本略高,但抗干扰能力强,检测可靠,是目前比较理想的一种实施方案。论述了激光检测方案的实施。

Through a comparison between the physical method,laser method and infrared method from the desighing point,this paper mainly introduces the laser detection,discusses several solutions that can be used to solve the clearance exited between PSD and trains,argues that the laser detection is the best method despite of its higher cost.
