| 摘 要： | 介绍了一种为某大型企业设计的总线制多点监控系统的组成及电路设计，其中监控控制接口采用台湾合泰的ＨＴ１２Ｄ作为核心，而中央控制器的信息发送采用ＨＴ１２Ｅ作为核心来完成。该系统能实现对开关量信号和模拟量信号的采集，并能根据预先设置的逻辑关系，对各个采集点的参数进行控制，使其在的范围内变化。它在工业现场监测控制等领域中有着广阔的应用前景。

| Abstract: | A bus type multi point monitoring system is introduced with HT12D used as its monitoring and control interface and HT12E for signal transmission of the central controller. The system can collect digital and analog signals and control parameters at multiple collecting points based on pre set logic relations and limit their changes within pre determined range. This system will have a wide application in industrial spot monitoring and control. |
