摘　　要：针对目前惯导测试系统只能测试一组产品的现状,设计了一种能实现4组惯导产品同时测试的基于微控制器LPC2368的多串口数据接收系统,以提高效率。在综合分析测试需求的基础上,通过对微控制器LPC2368软硬件的设计实现了四路串口数据的同步接收,并且使用USB总线将四路串口数据通过中断传输的方式将数据实时快速上传至测控计算机。通过使用VC++6.0软件的编写完成上位机应用程序的设计,实现了四路串口数据实时的显示、存储及标定。通过大量实验,并对得到的实验数据进行统计和分析,结果表明该系统实现了同步无错误接收四路串口数据的设计要求,具有很好的实用性。Inertial navigation system for the current test can only test a group of products,multi-serial data receiverbased LPC2368 microcontroller systems are designed in order to improve the efficiency of a product which can be achieved simultaneously tested four groups of INS.On the basis of comprehensive analysis of test requirements,the LPC2368 microcontroller software and hardware are deigned to receive four synchronous serial data,and the USB bus is used to four serial data transmisson by interrupting the way,the data is uploaded to the control computer in real time.By using VC＋ ＋6.0 to complete the preparation of PC software applications design,the four serial data real-time display,storage and calibration are realized.Experimental data for statistical and analytical analysis show that the system achieves error-free synchronous four serial data receiving design requirements with good usability.
