Study and Design of Distributed Industrial Safety
Measurement System Based on Infrared Technology

 Based on the photoelectric conversion characteristic of the infrared sensor, the detection signal is collected and processed by the AT89C51,which is consisted the core of the system. 89C51 controls the CAN bus controller SJA1000 and the transceiver PCA82C250 to form the CAN buscommunication system for transmitting data. Through the serial port MAX232 main controller can connect with each control node, monitor each controller in real time and renew the control scheme. This paper introduces the system work principle and part methods of hardware design in detail.
 At present, the survey about the parts of large or medium enterprises show that many manufacturing industries are lack of necessary safety protection equipment, even some high danger equipments are as well as, such as punching, forging, shearing and so on.The safety produces is only stayed in the education,and investments of safety protection equipment are overlooked. Otherwise, some safety protection equipments have no self safety monitor and control system, safety and protection equipment do not work in safe and exist a hidden peril, so that mistake operating or slacking in mind which can initiate man-machine accidents or accidentally rushing into danger area.The system completes the design of safety measurement through the CAN bus; it realizes the supervision and management of the danger area,prevents the accidents and protects the safety of peoples’ life.

 基于红外技术之分布式工业安全测量系统的研究分析

 基于红外传感器的光电转换，测量信号才得以被系统的核心--AT89C51收集和处理。AT89C51控制着CAN总线控制器SJA1000和PCA82C250收发器，以形成传输数据的CAN总线交流系统。通过串行接口MAX232,主控制器能够连接每个控制节点，对每个控制器实行实时监控并且更新控制方案。本文主要介绍系统工作的原理以及硬件详细设计的部分方法。
 当前，针对部分大中型企业的调查显示：许多制造行业缺乏必要的保护设施，甚至是高危险性设备的也是如此，例如冲压机、锻造、剪切等。安全生产的概念只是停留在教育培训阶段，而安全保护设施的投资却被忽略了。另外，一些安全保护设施没有自身安全监测和控制系统，则不能有效工作并存在潜在危险。而这些危险则会导致由误操作和开小差等引起的人机事故，和误闯危险区等现象。系统通过CAN总线完成了安全性测量的设计；这实现了对危险区的监督和管理，阻止了事故的发生的同时保障了人们生命的安全。
