ABSTRACT Temperature is a basic physical quantities, he is the most common in the process of industrial production, one of the most important process parameters。 With the continuous development of industry, more and more is also high to the requirement of temperature measurement, and the range of measurement is becoming more and more widely。 Reasonable temperature range and temperature accurately metering to improve product quality, yield, lower consumption, realize the industrial production automation, have a positive effect, so the temperature detection technology research is of great significance。

This system is a temperature detection system based on LabVIEW, adopts multi-point temperature detection, can detect the temperature change in large area, this paper introduces the Arduino, LabVIEW two platforms based a temperature detection system working principle and design method of using two platforms their advantages to complete the rapid development of the system。 Mainly includes the upper machine and lower machine two parts。 Upper machine and lower machine communication methods is a serial port communication。 Upper machine is composed of computer and the LabVIEW software, responsible for the system control and data processing。 Under a machine is composed of the Arduino microcontroller and sensor, is responsible for data collection。 In the practical use can improve the accuracy of the detection and reduce the manpower cost, ensure to detect the change of environmental temperature at any time。 The system can well solve the problems existing in the traditional test methods, has a certain practical value。

Key words: temperature measurement on the Labview Arduino microcontroller
