DEVICE AND METHOD FOR CONTROLLING WIRELESS SENSOR PERFORMABILITY Russian patent published in 2017 - IPC G05B23/00 G01L23/22 G01F23/00 G01K15/00 

FIELD: physics.

SUBSTANCE: device for controlling wireless sensor performability contains a reception block, a memory block, an analysis block and a control block. The interrogation block is adapted to request the readings from the wireless sensor and to store them in the memory block. The memory block is adapted to store the signals from the sensor. The analysis block is adapted to identify the noise component in the stored signals from the sensor and to calculate the value of the SD (standard deviation) of the noise component and to record this value in the memory block. The control block is adapted to detect changes in the received signals from the sensor as the difference between two successive signals from the sensor and the issuance of a fault signal, if changes in signals from the sensor do not exceed 6 SDs for a predetermined time T_cont. Moreover, the above-mentioned blocks are functionally connected to each other directly or indirectly via communication links. The method for controlling the wireless sensor performability is also stated.

EFFECT: increasing the reliability and accuracy of the sensor failure detection.
