Broadcast Signal Design And Implementation Of Remote Automatic Monitoring System

In This paper, real-time detection for voltage and current signals of medium wave radio transmitter under the power rating is studied. The system uses master-slave architecture, master machine using PC and slave machine using AT89C52 MCU. The master can sample the data of point in real time. The slave machine,collect real-time data ,automatically answer the call and upload the data on PC.In this paper, a smart detection system based on AT89C52 MCU is designed, including hardware modules and software module design, the detail hardware circuit plans and software flow chats are also given. The main hardware module is composed of microprocessor AT89C52, analog signal and switch signal transmitting and receiving unit, man-machine interface unit, MODEM communication interfaces. Software Module Design include the main program,communication Program,A/D converting Program, display Program。The MCU application in automatically remote detection of Medium Wave Broadcast signal reflects development and application of intelligent technology, the computer hardware; software and related technology are analyzed and researched in this paper.
