【摘 要】现代社会,液位远程监控器已十分普及。当前,诸如石油、化工、造纸、食品、制药、轻工、污水处于等众多领域的自动控制系统中,都不乏液位远程监控器的身影。至于液位远程监控器的主要作用,其主要是一种自动控制元件,其在自动控制系统中的运用,不仅可实时监测液位,且能通过设置液位的上限与下限来同步控制泵的运转,一旦液位高于或低于其所设置的上下限值,则报警器会进行报警,而泵亦会同步停止运转,以防止设备损坏。

【Abstract】In modern society, liquid level remote monitors have become very popular. At present, there is no shortage of liquid level remote monitors in automatic control systems such as petroleum, chemical, paper, food, pharmaceutical, light industry, and sewage. As for the main role of the liquid level remote monitor, it is mainly an automatic control element. Its use in the automatic control system can not only monitor the liquid level in real time, but also can synchronously control the pump by setting the upper and lower limits of the liquid level. Operation, once the liquid level is higher or lower than the set upper and lower limits, the alarm will alarm, and the pump will also stop running to prevent equipment damage.

当前的液位远程监控器,其主要的控制原件有:信号传输线路、信号接收单元以及液位感应器。其中,液位感应器无疑是最主要的信息采集设备,在液位远程监控器实际的运转过程中,液位感应器会将其所接收到了电信号,经由传输系统传送到信号接受单位,而当信息接受单位接收到相应地信号后,便会自动开始进行处理。当然,该过程将全部显示在远程控制端的电脑上,相关的微机操作人员便可轻松基于信号接收单元所传递出来的信号来判断当前液面是否处于正常位置,进而保证机器的正常运转[1]。如今,随着我国工业自动化的不断发展,液位远程监控器已逐渐被运用到了更多的领域,而本文将作者对典型液位控制系统展开研究。
1 液位远程监控器基本概述
据表1所示,我们可以看出,液位远程监控器最主要的原件包括传感器、单片机、液晶显示器、AD转化器以及液位报警器。……
