The Design And Implementation Of The Software System For Testing The Dsada On The Ground

By the development of the aerospace industry and the rapidly developing of high-tech industries,the technology of detection and control in aerospace industry has also been rapidly developing, especially the technology of detection and control in the satellites and the small satellites has been widely used and rapid development.This paper is about the design and implementation of the software system of the detection and control equipment for the dual-axis solar sails on the ground. And it talks about requirements, design and implementation of the software system.Frist we will talk about the requirements of the system, including the whole frame about system's functional, the system communication requirements, the system functional requirements and Non-functional requirements. The design of the system is mainly introduced the system communication design, system design of communication Frame, the system's serial port design, serial communication system design, system design and system information in real time query function module design. The implementation in the system's function model introduced mechanical characteristics of the system model, YanHua 4017 acquisition model, the system calibration model and circuit box model. Towards the introduction, the main basis is designed to introduce the implementation of the system registry, the system achieved frame communication, systems and implementation of serial communication, system information and system implementation of real-time query function of the realization of each module, the function modules The main mechanical characteristics of the system is to introduce the module function implementation, the system Advantech 4017 module function implementation, the system calibration module function implementation and system circuit box module function implementation.For calls for real-time states command uses the finite state machine theory as the theoretical basis of the polling mechanism to solve, and call control commands to achieve the orderly and timely response.By research on this article, and ultimately the dual-axis solar panels ground test equipment design and development of software systems to achieve the requirements of the demand.
