一种指令可编程的音频切换器智能控制系统

摘要

For the lack of generality of control system for different audio switcher, an audio switcher intelligent control system is developed on . Net Framework 4. 0 and WPF. Based on the thought of directive programmable, the business logic and the data process-ing and user interface were completely separated. All of the control commands and configuration information were pre-stored in the XML file. They were loaded dynamically when the system is running. To realize the automatic control of different brands of switcher, the pro-grammable instruction set is modified in the configuration information directly, and it isn' t necessary to recompile the entire control software. Therefore, the versatility of this system was improved.%针对音频切换器的控制软件缺乏通用性的问题,基于. Net 4. 0和WPF,开发一套音频切换器智能控制系统. 该系统采用指令可编程的思想,将业务逻辑、数据处理及用户交互界面完全分离开,并将不同品牌音频切换器的控制指令和配置信息预先存储于XML文件中,当接入某切换器后,在程序运行时动态载入. 该系统直接通过修改配置信息中的可编程指令集来实现对不同品牌切换器的自动控制,不需要对整个软件进行重新编译,从而提高了系统的通用性.
