加拿大国际镍公司伙同自动化采矿系统公司等历经五年研究,开发了一个供地下矿山用的通信和信息系统。该系统可借助单一电缆系统同时实现控制、数据采集、话音通信和视频监视,为矿井通风、排水、计算机局域网、车辆完好状况等提供监控和自动化服务;基于可编程控器进行监控和数据采集;还可借助该系统进行双向无线电话通信、闭路电视、寻呼和设备遥控等。
After five years of research, Canadian International Nickel Corporation, together with the automated mining systems company, developed a communications and information system for underground mines. The system enables simultaneous monitoring, data acquisition, voice communication and video surveillance with a single cable system to provide monitoring and automation services for mine ventilation, drainage, computer LANs, vehicle integrity, etc .; monitoring and data acquisition based on programmable controllers; The system is also used for two-way radiotelephone communications, closed-circuit television, paging and remote control of equipment.
