1.引言超长距无中继通信系统具有端到端直达通路,无任何中继设备和建设,运营维护成本低等特点,对于像我国这样幅员辽阔的地区,可有效解决大城市间搭建长跨距直达路由,提高通信效率;同时,可有效解决通信路由经过沙漠,沼泽,森林等无人区的问题;特别是对于我国目前进行的跨大区,特高压输电线路的通信系统而言,无疑是一个非常好的解决方案。因为,电力通信线路与普通的通信线路不同,电力通信线路路由走向
1. Introduction Ultra-long distance relayless communication system with end-to-end direct access, without any relay equipment and construction, low operation and maintenance costs, for such a vast area as China, which can effectively solve the construction of large cities between the long Span direct routing, improve communication efficiency; the same time, can effectively solve the communication routing through the desert, swamps, forests and other non-man-made problems; especially for our current cross-regional, UHV transmission line communication system, Is undoubtedly a very good solution. Because, power communication lines and ordinary communication lines are different from the power line communication route to
