Abstract: As the development of the carrier-current technology, the predominance of the carrier–current communication is more obvious. This article will introduce an auto control system that implements the carrier-current communication by LM1893 IC, manages the information synthetically by PC and controls the electro-equipment by single chips. The communication of a RS232 serial port in PC and many single chips comes true by serial communication mode. The energy conservation system in the classroom comes true by the method introduced in the article and achieves the design purpose.
Key words: Carrier-current; Single chip; Energy conservation
引言
随着电力载波通信技术的日趋成熟，电力载波 的研究也逐渐成为热点。电力载波通信以电力线路为传输通道，由于低压电力线随处可见，利用现成的低压电力线传输信号就不必要再架设专门的通信信道，系统设备可就地接入电力线，这就使的通信成本大幅度降低，投资少，见效快，并且可以实现与电网同步建设等。电力载波通信技术可广泛应用于工业自动控制系统[1-2]，自动抄表系统[3]，医学领域[4]，电器设备控制系统[5]，防火报警系统[6]等场合。电力载波通信在很多领域都可体现出其无可比拟的优越性。本文介绍了一种以LM1893集成芯片实现电力载波通信的方法，并研制了一套基于单片机控制的电力载波通信装置。
