To do Validation and Verification" of wireless vibration sensor nodes in NPPs (nuclear power plants), embedded system software test should be done. The test index is analyzed firstly; then the method of 'Temb' was introduced to analysis ADXL202 vibration nodes; the characteristic of system was used to establish LITO(life cycle, Infrastructure, Techniques, Organization) matrix, they are of emphasizing safety, application in harsh environment, using algorithms of technology and science and so on. The acceleration circulation method using fixed time cycle pretest by instrument and other weak was proved to be infeasible though FMEA (failure modes and effects analysis). Then FTA (fault tree analysis) is used to analyze system, so the software filter and real-time cycle test method were used to improve test precise and reliability of node vibration measurement. Experiments have proved its effective.
