Abstract:This paper proposes an automatic monitoring system of radio and television signals to change the traditional way of manpower periodic testing.The front-end device of provided on the multiple monitoring points within the coverage area of radio and television，for receiving a broadcast television signal and the signal frequency, field strength，monitoring point name and other information，through the network to the processing terminal，automatic detection and analysis monitoring point signal field strength.The front-end equipment uses the microcontroller as the core, connecting antenna and frequency selective circuit, detection circuit, analog to digital converter, digital to analog converter and network transceiver, through the software cycle selects frequency, processing field strength data. The network transceiver enables the front-end devices to access the internet in a wired or wireless manner to handle terminal connections and data interactions.The processing terminal uses the desktop PC, laptop PC or handheld PC as the platform to remotely receive the data transmitted over the internet through software, and stores and displays the signal frequency, field strength, and monitoring point name of the front-end equipment on each monitoring point.System operating normally, data is accurate, convenient, reliable, time-saving, promotion of high value.
