运用微型计算机开拓光栅数显器的新功能,除具有一般数显器的清零、置数、可逆计数等功能外,并增添了无效零自动消去显示方式;停电时保护可编程存储功能;光栅传感器的原点检出;为机床提供定位座标;座标点的测量值除2运算定出中心值;监视光栅传感器和超速报警及自校等新功能。列举了微机配置,数据采集接口及程序框图。 The use of micro-computer to develop new features of the grating digital display, in addition to a general digital display reset, set the number of functions such as reversible counting, and added invalid zero automatically eliminate the display; power-off protection of programmable memory function; grating The origin of the sensor is detected; positioning coordinates are provided for the machine tool; the coordinate values ​​of the coordinate points are divided by 2 to determine the center value; the new functions such as grating sensor, overspeed alarm and self-calibration are monitored. Lists the computer configuration, data acquisition interface and the block diagram.
