VB环境下积木式工业测量系统的数据通讯

工业测量系统是测量技术较新的应用领域,国内已有多家单位从事该系统的研究和开发。而两台或多台测角设备同时与一台计算机的数据通讯,是组建该系统的关键技术。本文首先简要介绍了数据通讯和VB中的MSComm控件,然后以TM5100A电子经纬仪和EltaC20A全站仪为例,重点论述了“多对一”式的数据通讯流程和方法。该方法简便而有效,用简单的控件和程序代码即可实现测量数据的实时采集与入库存储,能成功实现系统所要求的通讯功能。

Data communication in industrial measuring system of "building blocks type" based on VB

Industrial Measuring System (IMS) is a new domain of surveying technique, and there are many researches about its development. Among such studies, it’s a crucial problem how to realize two or more angle-measuring instruments communicating with one computer simultaneously. The paper firstly gives some brief summarization about data communication and VB MSComm control. Then, taking TM5100A theodolite and Elta C20A total station for example, data flows and communication methods of "multitude to single" type are stressed in detail. Such methods are simple but effective. On-line collection and storage of surveying data can be realized by simple VB controls and program codes. It not only solves communication problem of IMS, but also gives some help for data communication of similar types.
