Design And Implementation Of Channel Selective Repeater Monitoring System

Due to the inherent characteristics of electromagnetic wave propagation, even in therapid development of mobile communications today, but still exist many base station signalscan not be covered, the repeater provides a wireless coverage solutions to solve this problem,it has a low-cost, easy installationfeatures, has a base station can not be replaced. With thelarge-scale application of the repeater, working stability operation and maintenance simplicityis becoming increasingly important, this paper presents the design and realization of arepeater monitoring system.According to the features of the repeater and the Guangdong Mobile Repeatermonitoring requirements, it given the core circuit design and detection circuit design based onARM core the STM32F107processor, it also given the front-end software architecture designand implementation based on μCOS-II operating system. LMT(Local Maintenance Terminal)side with the configuration software to query and set the parameters of the repeater throughthe configuration software, the relevant status can also be reported to OMC (Operation andMaintenance Center) in real time.
