The Embedded Software-Based Design And Implement Of Multi-Group Terminal Simulator

At present, Digital switching devices are applied widely in human society each field, increasingly at communication, traffic, medical treatment, education, and even space field. And at digital communication, voice communication is one of the most general and the most basic project. For a long time, digital switching device's voice communication capability test is mainly depended on manual work; workload is great, repeat work is to much more. So, we need avidly automatism digital switching device's voice communication capability test, this is the Multi-group Terminal Simulator.The author, through reviewing test and use requirement, accumulates long period practise experience at work, analyses entirely the requirement of the Multi-group Terminal Simulator, demonstrates sufficiently possibility of implement, applies software engineering theory to achieve the software part(singlechip and GUI) particular design, completes great code programming,debug work, and completes the device practicality manufacture,uses it to actual test work.The Terminal Simulator is mainly used for switching capability testing of simulation consumer communication. The device can be used with one switching between two consumer interfaces or between two switchings testing of communication capability. It is convenient for testing personnel to test automatically communication capability of switching.The paper discusses mainly the Multiple Terminal Simulator achieving methods through embedded software design, at the aim to master foundation method of embedded software development, be familiar with basic syntax of C programming language, and debugging software Keil uVision2 development methods and skills.This thesis mainly completed the following work:①Discusse the significance of reseach, select technique line;②Discusses detailed design of the Terminal Simulator embedded software, detailed describe embedded software of singlechip;③Detailed design human-machine interface software of the Terminal Simulator software, detailed describe software design of human-machine interface;④Apllication and test of Terminal Simulator, detailed describe using way of equipment applied in digit switch testing. Research summarize and expectation to later work.
