Environmental pollution automatic monitoring system, a monitoring network for continuous automatic sampling, measurement, information transmission and data processing of environmental quality. It consists of several fixed monitoring stations (some have mobile monitoring stations), a monitoring center and data communication system. The common ones are automatic air pollution monitoring system and automatic water pollution monitoring system. The long-term continuous real-time data provided can play an important role in determining the distribution of local pollution sources, environmental pollution and hazards, setting environmental quality standards, and making pollution forecasts.
