摘要
为解决用户分散地区,自然及人为障碍物(如高山、大型建筑物、隧道和地下商场等)的阻挡和屏蔽的通信问题,提出一种无线直放站监控系统。采用单片机W77E58、M AX1487、CC1000等芯片,设计光远/近端控制模块电路。通过自动衰减控制(ATT)设置,实现完善的直放站近端、远端的监控、管理、维护等功能。
In order to solve the problem of communication such as service area of widely dispersed users, natural and man-made obstacles, such as mountains, large buildings, tunnels and underground market, a wireless repeater monitoring system is put forward. The single chip microcomputer W77E58, MAX1487, CC1000 and other chips are adopted to design control module circuit of optical far-end/terminal. Through the ATT setting, the monitoring, management, maintenance and other functions of repeater are realized.
