WIRELESS MEASUREMENT DEVICE

To provide a wireless measurement device that can measure and transmit data necessary for a diagnosis even under communication standards that have a large restriction on communication volume.SOLUTION: A wireless measurement device 1 comprises: sensors 5A to 5D that measure a measuring object in a measuring object facility; a transmitting apparatus 11 into which the measurement signals are input from the sensors 5A to 5D, and which performs predetermined processing on the measurement signals, and wireless-transmits the processing results according to predetermined communication standards; and a receiving apparatus 21 that receives processing results sent from the transmitting apparatus 11. The transmitting apparatus 11 comprises: a data processing unit 12 that calculates a waveform feature amount for each predetermined time interval τ from the time-series data of the measurement signals; a storage unit 13 that stores the calculated waveform feature amount; and a communication control unit 14 that repeats an operation of wireless-transmitting the transmission data assembling Tt waveform feature amounts to the receiving apparatus 21 every time a quantity of the waveform feature amounts stored in the storage unit 13 reaches Tt, which is larger than a predetermined value of 1.SELECTED DRAWING: Figure 1 【課題】通信量の制限が大きい通信規格の下でも診断に必要なデータを測定及び送信できる無線計測装置を提供する。【解決手段】無線計測装置１は、測定対象設備の測定対象に対して測定を行うセンサー５Ａ～５Ｄと、センサー５Ａ～５Ｄから測定信号が入力され、測定信号に対して予め定められた処理を行い、処理結果を予め定められた通信規格に従って無線送信する送信機器１１と、送信機器１１から送信された処理結果を受信する受信機器２１とを備える。送信機器１１は、測定信号の時系列データから、予め定められた時間間隔τ毎の波形特徴量を算出するデータ処理部１２と、算出された波形特徴量を記憶する記憶部１３と、記憶部１３に記憶された前記波形特徴量の個数が予め定められた１より大きいＴｔ個に達する度に、当該Ｔｔ個の前記波形特徴量をまとめた送信データを受信機器２１に対して無線送信する操作を繰り返す通信制御部１４とを備える。【選択図】図１
