摘　　要：介绍了一种基于AD9430的数字接收机的设计,给出了系统实现的具体方案,并对各部分硬件电路的设计进行了阐述.对FPGA内部各主要功能模块设计做了详细介绍,给出了各功能模块的具体实现结果,并通过仿真验证了各功能模块的正确性.该系统可以在硬件平台不变的情况下,通过改变软件程序实现不同功能和技术指标的系统,具有较高的通用性和实用价值.Aiming at the intelligent sand-tray model of Harbin metro＇ s first phase project, the metro＇ s sand-tray intelligent control system was developed based on VC＋＋ . Visual C ＋ ＋ 6.0 is used in the PC （upper computer） of the control system and an auto-play interface of touch screen control is designed. The software could keep the real-time communication with the lower computer while automatically displaying the multimedia information. Tile multimedia part of the system fully embodies automation and intelligence. The lower computer - PLC collects the field data and controls the actions from all the devices in the field. In order to keep the system away from conflict when multiple interfaces are calling resources in serial port, an effective solution and its software flow are practically given and it proves that the system can run stably and safely.
