鸟曾经是矿工用以检查井下大气是否存在危险的唯一手段。今天,采用电子传感器与计算机相连,借助于声、光报警装置,硬拷贝复制设备和显示终端,可以即时报告什么地方发生了故障,需要什么人去修理。矿井监控程序现在已能方便地购买到,其容量和能力虽然各不相同,但有许多共同点,大多数都是以微型计算机为基础的, 多数的方案是把注意力放在监控功能上,但也可扩展到用以管理手动控制和在空间时间安排设备维修。中央监控器不断地扫描所有
Birds were once the only means miners used to check the underground atmosphere for danger. Today, with electronic sensors connected to a computer, with the help of audible and visual alarms, hardcopy copy devices and display terminals, you can instantly report where something went wrong and who needs to be repaired. Although mine monitoring programs are now readily available, their capabilities and capabilities vary, they have many things in common, most of which are based on microcomputers, and most are focused on monitoring functions, But can also be extended to manage manual controls and schedule maintenance of equipment in space. The central monitor constantly scans all
