Design of fast frequency hopping device of locating communication system under mine

针对目前矿井下定位通信系统慢速跳频不能满足信息采集的现状,提出一种可供矿井下定位系统使用的快速跳频器设计方法。阐述了快速跳频器设计原理、AD9954的电路设计、RS跳频器的设计流程和位同步的实现流程。该跳频器的设计能为矿井下定位通信系统提供可靠的信息采集,提高系统的抗干扰能力和信道利用率,可应用于矿井等地下工程。

Aimed at the slow frequency hopping of locating communication system under mine （ LC-SUM） which fails to fulfill information collection, the paper introduces one design approach of fast frequency hopping device designed for LCSUM. The paper features design theory of fast frequency hopping device, circuit design of AD9954, design flow of RS （Reed-Solomon） frequency hopping device and implement flow of bit synchronization. The use of the fast frequency hopping device enables reliable and fast collection of information of LCSUM and improvement in anti-interference and channel utilization of LC-SUM. This device can lend itself well to mines and other underground projects.
