摘　　要：介绍了自动扶梯电气安全保护系统的一种新的设计思想：在安全检测上加入独立智能安全模块，利用闭环控制形成多通道检测回路．作智能判断；在系统中，主控电脑板成了安全器件而被检测。而安全模块则被主控电脑板当作安全器件来检测，安全检测处理变为软硬结合，使整个安全检测系统成为一个有机整体。A new design idea of the electrical safety protection system of escalator, adding independent intelligent safety module into safety detection, forming multichannel detection circuit by closed loop control, making intelligent judgment is introduced. In this system, the master control computer board is detected as a safety device, and the safety module is also detected as a safety device by the master control computer board. Thus the safety detection combines hardware with software, and the whole safety detection system becomes an organic whole.
