基于虚拟机思想的测控软件--通信实现

早期开发的测控软件可移植性和可维护性较差,并且在开发大型测控软件时,软件系统的建模工作难度大,系统开发周期长.HyperPanel PC Boot Direct测控软件开发系统所提供的各个开放模块适应测控软件的模块化结构,使用该系统开发测控软件不仅可以降低开发难度、缩短开发周期,而且所开发的测控软件可维护性和可移植性较好.文中首先介绍了HyperPanel PC Boot Direct开发系统的特点以及该系统所使用的开发语言--Pantalk语言,给出了利用该系统开发测控软件的流程,最后介绍了在此平台上实现的RS-232通信程序的组成模块、各模块的关系以及各个组成模块的结构,并给出了主要模块的实现技术.

Test and Control Software Based on Virtual Machine and its Application to Communication

The transferability and maintainability of early test and control software were bad. It is difficult to model the software system to be developed and will cost much more time to realized it. The open module provided by HyperPanel PC Boot Direct suits the modularized structure of test and control software. Using this system, it will be much more easier and cost less time to develop test and control software. The transferability and maintainability of the product will be much more better. First, this paper introduces features of HyperPanel PC Boot Direct and Pantalk language. The flow chart for developing test and control software using this platform is given. Then, it describes an applicable RS-232 communication program for the platform and introduces the modules that compose this program, and the relation ship between the modules and the structure of these modules. At last, it reveales the detailed technology for developing the main module of the communication program.
