Abstract: 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 processing 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 programmable 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.
