开发了一套智能仪器实验教学系统,该实验系统由数据采集系统和以SST89V564RD单片机为核心的数据分析处理系统组成.整个系统采用模块化设计,包括单片机模块、人机接口模块、数据采集模块、简易信号源模块等.信号源由系统自带的信号源提供,也可外接信号源.数据采集模块通过串口采集数据,经由单片机编写的数据处理程序进行分析处理,由上位机软件显示原始数据波形或处理后数据波形.实验证明,该系统运行稳定,可满足智能仪器实验的教学目的.%An experimental teaching system for intelligent instrumentation was designed in order to meet the requirement of experimental teaching, which was successfully applied to the undergraduate teaching. The system was composed of a data acquisition system and a data processing system with SST89V564RD single-chip microcomputer as the processor. The modularized design was adopted in this system, and the single-chip module, man-machine interface module, data acquisition module, and simple signal source module, etc. Were included. The signal source can be provided either by the system or by an external signal source. The data acquisition module transmits the data by the serial port, and then the data will be analyzed. In the end, the PC ( personal computer) software displays the raw data and the processed data. Experiments proved that the experimental system can satisfy the experimental teaching purpose and runs stably. The most important is that this experimental system can help students understand intelligent instrumentation by doing experiments, and can consolidate what they learned in class.
