提高计算机控制系统模拟量输入精度的方法

A Way to Improve Input Precision of Analog Signals in Computer- Controlled System

计算机可直接对数字量进行处理 ,对于模拟量需将其转换为数字量后才能被计算机接受。如将模拟量通过变送器转变为脉冲信号再送入计算机 ,可减少这些转换环节 ,提高测量精度和可靠性。

Though the computer can process the digital signals,the analog signals to be processed by computer must be converted into the digital ones.If the analog signals are transformed into pulse ones with a converter,measurement presision and reliability can be improved considerably.
