在现代检测技术中,经常需要对智能仪器内部的多路直流电平进行实时检测,从而得知工作是否正常。为此以ATmega16单片机为核心器件,采用内部ADC、加减运算电路以及三参数软件精度校准方法来设计一种测量系统,可以对-10 V~+10 V量程范围内的多路直流电平进行实时检测并用数码管显示。该系统通过proteus仿真以及对两路电平进行实际测量,误差范围≤0.02 V,且体积小、结构简单、工作可靠、响应速度快,可作为实际应用。

In modern detection technology, real-time detection for multi-channel DC level inside the intelligent instrument is required frequently to ensure its working properly. ATmega16 microcontroller is used as the core device,using the internal ADC,the addition and subtraction operational circuit,and the precision calibration method of three-parameter software to design a measurement system. Multiple DC level of -10 V ~+10 V range can be monitored real-timely with digital display. Proteus simulation and actual measurement were both used in the system, which showed the error did not exceed the scope of 0. 02 V,together with the characteristics of small size,simple structure,reliable work and fast response made it work properly in practical application.
