摘　　要：介绍了一种为电子经纬仪开发利用AC40 73数字I/O板的并行数据通讯方法和相应的控制软件 ,使得PC微机能够通过所设计的并行数据通讯电路与电子经纬仪进行实时通讯。讨论了并行通讯方法的硬件原理、工作过程和通讯软件的设计及例程 ,利用这一通讯方法可以达到利用PC微机对电子经纬仪测得的水平和垂直角度进行自动采集和处理分析的目的。A parallel data communication using an AC4073 digiboard for the electronic theodolite is introduced and the corresponding software is developed for PC computer, in order that PC computer can in time communicate with the electronic theodolite via the designed parallel data communication circuit; the principle and the work process of the designed parallel data communication are discussed and the design and routines of the communication software are debated. With the parallel data communication, the automatic acquisition and the further analysis of the horizontal and vertical angle measured by the electronic theodolite can be done by the PC computer.
