WIRELESS SENSOR NODES AND METHOD FOR DIAGNOSING SENSOR NODE FAULTS

摘要

PURPOSE: A wireless sensor network device and a sensor node malfunction detecting method thereof are provided to diagnose the abnormality of a sensor using a multi sensor. CONSTITUTION: A sensor unit(110) measures the specific physical quantity. A memory unit(120) stores the predetermined binary patterns. A wireless communication unit(140) transmits the binary patterns and the measured value to the server. A controller(130) controls the sensor unit, the memory unit, and data transmission between the wireless communication units.
