近年来,PHS(小灵通)在煤矿的成功应用不仅解决了煤矿井下无线通讯的难题,而且还因其技术成熟、信号稳定、安全可靠、便于维护、扩容方便等特点被中国煤矿优先选用作为井下通讯的解决方案。PHS系统的一般结构是由有线和无线两部分组成。有线部分包括基站控制器,无线基站等部分组成; 无线部分是指无线基站和手机之间的联系,也就是我们一般理解的无线通讯。 In recent years, the successful application of PHS (PHS) in coal mines not only solves the problem of wireless communication in coal mines, but also is preferred by China’s coal mines because of its mature technology, signal stability, safety and reliability, ease of maintenance and expansion. Communication solutions. The general structure of PHS system is composed of wired and wireless two parts. Cable parts include base station controllers, wireless base stations and other components; wireless part refers to the link between the wireless base station and mobile phones, that is, we generally understand the wireless communications.
