在数字计算及其工程控制方面,常常需要把某一机械位移量或转角量变为二进位数码,以适应数字计算和控制。为了完成上述编码,有些采用电感移相器进行传递并编码;有些采用自同步机三相电压编码;有些采用电刷式葛莱码编码;有些采用光学葛莱码编码。由于数字计算技术的迅速发展,这类编码器的用途越来越广泛,用量也越来越大。它的用量,有如机电模拟机中经常采用的自同步机、传感器一样。因此,设计者希望这 In the field of digital computation and engineering control, it is often necessary to change a mechanical displacement or angle into a binary digit to accommodate numerical calculations and controls. In order to accomplish the above encoding, some adopt the inductive phase shifter to transmit and encode; some adopt the self-synchronous machine three-phase voltage to encode; Some adopt brush type Gelai to encode; Some adopt the optical Gela encode. Due to the rapid development of digital computing technology, the use of these encoders is becoming more and more widespread and their usage is also growing. It’s dosage, as often used in mechanical and electrical simulator since the synchronous machine, the same sensor. So designers want this
