摘　　要：根据多种应用环境下的多点温度测量,设计出一种便携式多通道温度数据采集系统.利用热电偶作为温度传感器,传感器信号经NI9211四通道热电偶输入模块进行信号调理后通过USB总线输入计算机进行分析和显示.系统软件设计基于LabVIEW图形化开发环境,各项参数可灵活设置,在多点温度测量方面具有良好的应用价值.For multi-point temperature measurement in various environments, a portable multichannet temperature data acquisition system was designed. Making use of the thermocouple as the temperature sensor, the signal of thermocouple is modulated by NI 9211 4-channel thermocouple input module, then sent into the computer through the USB bus for analysis and display. Based on a graphic development environment of LabVIEW, and with the flexible configurations of all parameters, the system software has a good applicable value in the multi-point temperature measurement.
