本文介绍一个以MIC—80微机为主体的数据采集系统。对于非电量的物理量经过传感器转换成电量,这类的模拟信号,其信号的输入范围在0～5伏或-2.5伏～+2.5伏,模拟信号的頻率范围在0～100HZ。本数据采集系统可采集分辨率为八位的八个通道(由用户自选)的数据量,供微机分析处理,从而实现对某物理量的实时控制和测量。为了方便用户,本系统同时用BASIC语言输入数据采集子程序,并用BASlC语言调用这个目的集子程序,应用灵活。
This article describes a MIC-80 microcomputer as the main data acquisition system. For non-physical quantities converted into electricity by the sensor, this type of analog signal, the signal input range of 0 to 5 volts or -2.5 volts to +2.5 volts, the analog signal frequency range of 0 ~ 100HZ. The data acquisition system can capture the resolution of eight eight-channel (user-selectable) data for computer analysis and processing, in order to achieve a physical amount of real-time control and measurement. In order to facilitate the user, the system at the same time using BASIC language input data acquisition subroutine, and BASIC language called this set of subroutines, the application of flexible.
