采用软件校准实现自动跟踪式手操器无电位器设计

Design of non-potentiometer for automatic tracking manual manipulator using software adjusting

通过以自动跟踪式手操器4～20mADC模拟量输入和输出信号的零点及量程的校准为典型示例,介绍采用串行E2PROM并通过软件策应实现模拟量输入和输出无电位器的零点及量程校准技术,并给出了模拟量输出自动1:1跟踪输入的方法.

A manual manipulator of auto-tracking moder is introduced as a typical instance, which includes the function to calibrate the zero and measure range of 4～20mA DC analog as input and output quantities.A technique of series-wound E^2PROM and correspond software are adopted to carry out the zero and measure range calibration of analog as input and output quantities.A method of output analog tracking input analog automatically by 1:1 is put forward.
