摘　　要：以4通道低温测量仪表为例,详细介绍了在LabWindows/CVI 13.0开发环境下,使用RS-232串行端口与自由通信协议实现低温测量数据上位机采集的方法。The standard serial communication ports of RS-232 and RS-485 are widely used in many kinds of instruments and meters.Modbus and free communication protocols are the most common methods of transmitting information on the serial bus.The way to apply serial communication port and free communication protocol in LabWindows/CVI 13.0is introduced in detail based on 4-channel cryogenic temperature measuring meters.The measured temperature data is sent to PC via the RS-232 port.
