摘要

针对某些特殊环境中单杆控制装置与伺服系统距离远，造成电压衰减，从而影响精度等问题，设计了数字化单杆控制系统。介绍了数字化单杆控制系统的硬件设计方案，描述了主电路板设计原理；给出了数字化单杆控制系统的软件设计方案，描述了软件工作方式；最后分别综述了该系统可以实现的3种对外通讯方式及它们的工作原理。该单杆控制系统能够实现手柄两轴模拟电压值的AD采样、AD转换和数据处理，可以直接与数字接口计算机或数字伺服控制器进行数据通讯。实验结果表明：数字化单杆控制系统的采样精度可以达到10 bit，误差仅为0.098％，而且能够远距离传输；基本满足实现单杆控制数字化、小型化、集成化、模块化、稳定可靠、精度高、抗干扰能力强等要求。

Abstract

A digital handle control system was established to overcome the voltage attenuation and poor accuracy come from the handle control equipment far from the servo system in a special environment. Firstly

the design scheme of the system hardware was introduced and the design theory of the main circuit was described particularly. Then

the system software and its working mode were given. Finally

three kinds of communication modes were discussed. The digital handle control system can simulate AD sampling

AD transform and data processing for voltage values by a handle level and can complete data communication with a digital computer and a digital servo controller by a RS422 serial directly. Experimental results indicate that the sampling precision of the digital handle control system can achieve 10 bit and the error is 0.098%. These results satisfy the system requirements for digitalization

miniaturization

integration

modularization

higher precision

as well as strong anti-jamming.
