| Abstract: | A Thermal Measurement System(TMS) for greenhouse covering materials based on virtual instrument technology was developed, which included the design of hardware and software, the selection of sensors, and the method of dealing data. This system can not only realize the data acquisition of temperature, wind speed and the power of heating, but also carry out management and calculation. As a result, the stability of the experiment process increased, the measurement accuracy and experiment efficiency were improved. |
