In order to realize automatic testing of the platinum resistance temperature sensor,a wireless platinum resistance test system based on ZigBee technology is designed.The test data of many platinum resistances can be sunk to the main computer by the high precision micro endpoints,and the PC-based test software is designed in Windows system by using Delphi7.0 and SQL Server2000.The automatic testing system is realized with the function of data acquisition,processing,management and performance evaluation.The problem that requires lots of wires existed in the traditional testing system is solved,and the test efficiency of the temperature sensors is improved.
