根据企业结构,动力监控系统装置的构造式样是支线布置多层次的。最适用的层次分为3个层次系统,其中有多点干线的、辐射的和树枝式环状结构的,如图1。国外许多煤矿对控制井下设备的自动化监控系统很重视,如南非EnlProjects公司对ΜиддеΛбург煤矿的水选厂用硬件中继逻辑
According to the enterprise structure, the structural design of the power monitoring system device is multi-level layout of branch lines. The most suitable level is divided into three levels of systems, including multi-point trunk, radiation and dendritic ring structure, shown in Figure 1. Many foreign coal mines attach great importance to the control of downhole equipment. For example, EnlProjects of South Africa used hardware relay logic to water mills at the Μидде Λбург coal mine
