摘　　要：利用对射式红外线收发模块、记忆自锁继电器和语音录放模块,设计了红外对射式机床安全保护系统。当操作者未进入危险区域时,安全保护系统没有反应,一旦有人的身体或其中的一部分进入危险区域遮断红外光束时,系统立即报警,同时控制电路输出控制信号至机床安全执行机构,使机床紧急制动,从而避免机床设备的损坏和人身伤害事故的发生。机床安全保护系统为模块化结构,具有安全、可靠性高、通用性强、电路简单、维修方便、耗电省、成本低、工作稳定、对光容易、抗振动与抗干扰能力强等特点,适合在冲压机械、注塑机,数控机床、剪板机、弯板机、油压机等机床设备上安装使用。In order to ensure personal safety and prevent injury accident in machine tool operation, an infrared machine tool safety system was designed with infrared transmitting-receiving module, memory self-locked relay and voice recording-playing module When the operator does not enter the danger area, the system has no response. Once the operator＇s whole or part of body enters the danger area and shades the infrared beam, the system will alarm and output an control signal to the machine tool executive element, and at the same time, the system makes the machine tool emergency stop to prevent equipment damaged and person injured. The system has a module framework, and has many advantages including safety, reliability, common use, circuit simplicity, maintenance convenience, low power consumption, low costs, working stability, easy debugging, vibration resistance and interference resistance. It is suitable for being installed and used in different machine tools such as punch machine, pour plastic machine, digital control machine, armor plate cutting machine, pipe bending machine, oil pressure machine etc.
