【Abstract】 This thesis introduced the method of realizing acceleration sensor performance test platform based on 2.4G radio frequency chip nRF2401 and the test principle of the acceleration sensor performance and the method of realizing the acceleration sensor performance test platform in detail. In this system,it uses PIC single chip computer PIC16F877A to collect the sending data from acceleration sensor,them transmits the data into industrial controlling computer by radio frequency chip nRF2401 and simultaneously analyzes the gathered data by NI LabVIEW. The radio frequency technology solved the problem that in the data acquisition process the rotating part has had some difficulties in wiring with the standstill part and is able to gather the data fast and correct.更多还原
