The Osen Industrial Enterprise Noise Automatic Monitoring System has a CPA certificate and a CCEP China Environmental Protection Product Certification certificate that meets the HJ907-2017 standard. It has functions such as power-off protection and equipment clock calibration. The automatic monitoring system for environmental noise consists of a noise online monitoring substation, meteorological online monitoring equipment, and a noise monitoring management system. It automatically sends real-time noise monitoring data and meteorological monitoring data to the environmental protection system of relevant departments. The noise online monitoring substation should have the function of collecting and analyzing noise signals, and can store a certain amount of data. The monitoring substation and meteorological monitoring equipment should have a compact structure and good windproof, rainproof, dust-proof, and anti-interference functions. They should be able to automatically sample continuously for 24 hours, achieving unmanned and fault free operation for a long time.
