矿井新型电机车调度通信系统研究

New Underground Trolley Dispatching Communication System

研制开发了有线－无线调度通信系统，该系统通信效果好、结构简单、成本低、便于维护，有广阔的推广应用前景，该系统关键技术为频率选择、共信道干扰、转接台控制技术及阻抗匹配、接收机频率自动跟踪等。

A new wire-radio trolley dispatching communication system is developed. Its good effect, simple structure, low cost and convenient maintainability make the system more practical. The key techniques of the system are the choice of frequencies, the common channel interference, the controlling methods and the matching of impedance for 'talk-through' base stations and the AFT of receivers.
