System Overview

The YX-ENMS Environment Noise Automatic Monitoring System consists of the front noise sampling unit, data analysis unit, data acquisition and transmission unit and back computer and data processing software. Through various noise monitoring equipments which have been installed at various monitoring sites, the YX-ENMS Noise Monitoring System conducts quantitative calculations and analysis of noise levels in the monitoring region, uploads the data of noise levels monitored on the site to the information management system of the environmental monitoring. And at the same time, the system records and saves the noise at the exceed standard time. The system realizes the functions of real-time continuous monitoring, automatic saving sample and alarming at exceed standard situation.
