基于简化计算机与外部串行设备或其他计算机之间串口通信软件开发流程的目的,采用了依据串口通信原理使用LABVIEW作为上位机程序开发平台的方法,运用图形化程序语言搭建上位机串口通信监控界面.通过由虚拟串口通信驱动软件建立虚拟串口通道用于模拟上位机与外部设备数据通信过程的试验,可得出在建立两个对应串口的基础上文中设计的两种数据通信方式均可完整传输数据、且能够以一个指定的终止字符形式结束传输过程的结论.总的来说,本文设计的上位机串口通信程序简单易懂,相应的监控界面也简洁易用,两者结合在实际近距串口通信中拥有一定的实用与参考价值.%Based on the purpose of simplifying the process of developing the serial communication software between computer and external serial device or other computer. According to the principle of serial port communication,use LABVIEW as host computer program development platform. Its graphical programming language is used in establishing the monitoring interface of the host computer. Through Virtual Serial Port Driver(VSPD),virtual serial port channels are built in order to simulate the data communication process between the host computer and external device. So,here get the conclusion that with two corresponding serial ports, two data communication methods designed in the article can completely transmit data and the process can be finished by a specified termination character. In summary,this serial port communication program of host computer is easy to understand,its homologous monitoring interface is simple and easy-to-use. Both of them possess certain practical and reference value in actual short distance serial port communication.
