The test temperature using a K-wire thermocouple and ADAM acquisition card is designed labview8.6 platform-based programming. Collection of K-wire thermo couple temperature range of 0-1300 degrees Celsius. Use ADAM3039 and 3210 capture card. The topics to be achieved requirements are: to build hardware and software systems, heating water temperature within the boiler to be tested to observe changes in water temperature curve, a large number of experiments, changes in water temperature curve, get a standard determine the boilers at the bottom of the heating part of the quality of good or bad. And experimental data into the database, to facilitate future call. 【KEYWORDS】LabVIEW；temperature acquisition；temperature curve；database 目　录 TOC \o 1-
