摘要
应用电力载波传输技术和单片机技术,给出了一种军用库房自动测报系统的设计与实现。介绍了监测主机与库房监测分机的电路原理,并应用有源滤波器MAX275实现了抗干扰滤波,在滤除干扰信号的同时,对有用信号进行放大。测报系统具有安装简单、隐蔽性好、成本低、可靠性高的优点。
An auto measure and alarm system for military storehouse is designed and implemented based on power load carrier transmission and MCU. The circuit principle of monitoring host computer and storehouse extension computer is introduced in detail. The filter using MAX276 for anti-jamming is designed. Interferential signals are filtered and the PLC signal is magnified. This measure and alarm system has the following merits: simple installment, good hiddenness, low cost and high reliability.
