communication method of computer and total-station instruments of data at VB environment [Summary] this text mainly inquiry in to carried out communication between computer and the total-station instrument data under VisualBasic6.0(call VB as follows) environments. Two kinds of communication methods: the usage mscomm control and the function of windows API. The application that also combined a solid example to carry out their string to go communication Procedure and step. Finally carried on comparison and summary to two kinds of methods. [Keyword] Visual Basic 6.0 data communication the mscomm control All of the electronics total-station instrument because its function is strong and operate convenience and consumedly raised an open country homework efficiency. Therefore it just and gradually replace traditional diagraph instrument and it is expanded for an application. Although making use of the system menu function of total-station instruments can immediately complete normal regulations diagraph, monitor in the big dam safety, side the ascent transform a monitor etc. this kind of data is a little bit greatly and need solid the applied situation of processing data, it is will not satisfy demands only by function and amount of memory of instrument. The data at this time can be output a computer by the instrumental data exportation port, and the data can be processed and saved by software. Along with the extensive usage of calculator, many local open country digatial measure diagram method also need to carry out real-time transport. VB is released by the Microsoft company of according to visual programming language, its adoption faces to the program design method that object, affairs drives and operate simple, therefore doubly be subjected to program design personnels favor.Underneath with Leica Tc 2002 whole station instrument for example, introduce how to carry out the communication between computer and total-station in the VB 6. 0 environment by making use of
