摘要
本系统以MSP430F149单片机为核心,设计研发一款简洁的电流检测装置,主要包括功率放大部分、AD采集部分、LCD1602液晶屏显示部分、电流检测部分。主要通过单片机将采集到的电压信号进行内部运算,然后电流峰峰值、电压、频率和谐波显示在LCD1602液晶显示屏。与当前使用的大部分的电流检测装置不同,它可以进行多种环境下电流的检测工作,适用范围较为广泛且操作简单,成本与同等功能的电流检测装置相比也较为低廉。
This system takes MSP430F149 as the core to design a concise current detection device,which mainly includes power amplifier,AD acquisition,LCD1602 LCD display and current detection. Unlike most current detection devices currently used,it can detect low voltage 5V and city power 220V. It has a wide range of applications and simple operation,and its cost is relatively low compared with other current detection devices with the same functions. This system mainly carries out internal calculation of the voltage signal collected by single chip computer,and then displays the peak current,voltage,frequency and harmonic wave on LCD1602 LCD screen.
