Voltage measurement display device

Abstract

本发明公开了一种电压测量显示装置,包括:至少一个以上电压采集电路,所述电压采集电路包括连接控制开关的运放电路,所述运放电路连接稳压电路;所述电压采集电路测量出的电压信号输出至检测所述电压信号的单片机,所述单片机将检测后的电压信号输出至连接的电平转换电路,所述电平转换电路将检测后的电压信号输出至连接的液晶显示电路显示具体电压值。本装置实时检测每一个基本单元的电压,当某一个或几个电压低于最低工作电压要求时,能及时的发出报警;并且通过液晶把每次测量的电压显示出来。稳压电路有效的解决了正在使用的测试线的因意外断路而产生的比较高的正电压或负电压损坏电子元件的问题。
The invention discloses a voltage measuring and displaying device, comprising: at least one voltage collecting circuit, which is composed of operational circuit connected with the control switch and voltage stabilizing circuit. The voltage signal measured by voltage collecting circuit is output to a singlechip for detecting the voltage signal. The voltage signal measured by singlechip is output to a level switching circuit, which outputs the voltage signal to a liquid crystal display to display the voltage value. The device detects each voltage of basic unit at real time, when one or several voltages is lower than the lowest operating voltage requirement, the alarm is timely sent and the voltage can be displayed on the liquid crystal display. The stabilizing circuit can effectively solve the problem that the test line on using generates high positive voltage or negative voltage due to unexpected turnoff to damage the electronic component.
