This paper conducts research on the wireless acoustic detection method for transmission and substation IOT.For the application scenario of typical power equipment,the acoustically enhanced package is designed based on the characteristic that weak acoustic signals are easily drowned by noise,and the amplification of acoustic signals at specific frequencies is realized.Then,the integration of the acoustically enhanced package and the acoustic sensor is realized,and a wireless monitoring system is developed that can be used to measure the acoustic signal of typical power equipment,which can monitor and warn the operation condition of power equipment.Our wireless acoustic monitoring system is oriented to narrowband IoT in existing substations.Edge calculations and data uploads are performed according to the transmission substation equipment IoT sensor data specification,thus reducing communication bandwidth usage and enabling effective monitoring of complex operating conditions of typical power equipment.
