Photovoltaic power supply digital noise tester based on RDSS short message communication

Technical Field

The utility model relates to the technical field of environmental protection and electric power, in particular to a photovoltaic power supply digital noise tester based on RDSS short message communication.

Background

The wind power generator influences the noise contribution ratio of the surrounding environment, and the most widely covered noise is the superimposed noise of the wind sweeping sound of the blade and the noise of the engine room (within the range of 150 meters, more than 50 dB). The hum affecting the sensitive points of the surrounding residents mainly comes from noise pollution caused by the fact that a generator and a cooling fan at the tail of a cabin of the wind driven generator are in high-altitude environment to the surrounding environment through a cabin wall and a ventilation opening (when the wind driven generator set normally operates, the noise of the cabin exceeds 90 dB). According to the requirements of sound environment quality standard (GB3096-2008) and environmental noise emission standard of industrial enterprise factory boundary (GB12348-2008), the noise generated in industrial production places and the control requirements need to be regularly tested and recorded for the ambient noise of the wind power plant.
