摘　　要：基于高性能的MEGA2560单片机,设计了一款智能电视信号监测报警记录器。该报警器采用TA7666P和延时电路实现音频信号监测,采用MAX7452实现视频信号监测,采用检波器和A/D转换器相结合的形式完成电视发射机功率信号的监测。该系统的电路结构简单,性能可靠,能满足广播电视系统的信号监测需要。Based on high-performance MCU of AVR MEGA2560, a kind of intelligent TV signals monitoring alarm is designed. In this system, audio signal monitoring is detected by TA7666P and time delay alarm, and video signal monitoring is detected by MAX7452, and transmitting power monitoring is detected by demodulation and A/D converter. The circuit structure is simple and the performance is reliable. It can meet the requirements of the monitoring of the broadcasting and television signals.
