SENSOR TERMINAL, COLLECTION TERMINAL, MEASURED DATA COLLECTION SYSTEM AND METHOD

PROBLEM TO BE SOLVED: To collect measured data efficiently and safely.SOLUTION: One sensor terminal 11 is installed for each measurement object, and the sensor part 11a of each sensor terminal 11 is fitted to an air blower motor for the measurement objects. The sensor part 11a measures the magnitude of the vibration of the air blower motor at a preset measuring time. Each sensor terminal 11, when a set transmission period arrives, periodically transmits measurement data comprising a device ID and other factors in addition to a measured value. A portable collection terminal 12 receives measurement data, and acquires what have reception levels higher than a determined level as being valid. After collecting measurement data from each sensor terminal 11, the collection terminal 12 is connected to a PC 13. Measurement records including measured data are transferred from the collection terminal 12 to the PC 13, and accumulated therein.
