Ambient noise monitoring method and device based on sound level meter

The invention discloses an environmental noise monitoring method and device based on a sound level meter, and the method comprises the steps: enabling a cloud server to receive sound monitoring data collected by at least one sound level meter in a target scene of to-be-monitored environmental noise, and inputting all the sound monitoring data into a pre-generated noise abnormality recognition model, obtaining an output result of the noise anomaly recognition model; and the cloud server analyzes the environmental noise information in the target scene according to the output result, and takes the environmental noise information as an environmental noise monitoring result of the target scene. Therefore, the environmental noise monitoring method and the environmental noise monitoring system can realize automatic and intelligent monitoring of the environmental noise, are beneficial to improving the monitoring efficiency of the environmental noise, and can also improve the monitoring convenience of the environmenta
