为了对目标区域的广播信号进行监测，评估信号的接收效果，提出一种远程控制的广播频段监测接收机设计方案。接收机在远程控制中心的指令控制下，接收广播信号，对解调出的声音信号进行录音，根据信号场强、信噪比等指标评估接收效果，然后把监测结果上报给远程控制中心，实现广播频段信号的远程监测和效果评估。实际应用中，该接收机可大量部署于目标区域进行无人值守，避免外派很多人员进行实地监测，大大降低了工作难度和人力成本，具有较好的工程推广价值。
為瞭對目標區域的廣播信號進行鑑測，評估信號的接收效果，提齣一種遠程控製的廣播頻段鑑測接收機設計方案。接收機在遠程控製中心的指令控製下，接收廣播信號，對解調齣的聲音信號進行錄音，根據信號場彊、信譟比等指標評估接收效果，然後把鑑測結果上報給遠程控製中心，實現廣播頻段信號的遠程鑑測和效果評估。實際應用中，該接收機可大量部署于目標區域進行無人值守，避免外派很多人員進行實地鑑測，大大降低瞭工作難度和人力成本，具有較好的工程推廣價值。

To monitor the broadcast signal in target area and evaluate the receiving effect of broadcast signal,a design scheme of broadcast band monitoring receiver based on remote control is proposed. The receiver under the instruction control of remote control center,receives broadcast signal,records the demodulated sound signal,and evaluates receiving effect according to signal strength,signal?noise ratio and other index. Then the monitoring result is reported to the remote control center to realize the remote monitoring and effect evaluation of the broadcast band signal. In practical application,the receiver can be largely de?ployed in target areas to proceed unattended operation,which can avoid assigning many staffs to monitor on site,so the work dif?ficulty and the cost of human are reduced greatly,and it has better engineering application value.
