Problems solved by technology

However, the network functions of the existing on-line pollutant discharge monitoring devices are relatively single, and are often only for specific applications.
If there are many types of pollutants to be monitored, the scope is large, and the distribution of monitoring points is uneven, the existing online monitoring system is difficult to deal with

Description

technical field [0001] The invention belongs to the field of pollutant monitoring, in particular to a pollutant discharge monitoring device and system. The invention provides a pollutant discharge monitoring system including multiple data transmission modes and applicable to various application scenarios, which realizes real-time monitoring of pollutant discharge, network release and over-limit reminder. Background technique [0002] Since the 1980s, the impact of environmental pollution has become increasingly prominent and has become a global problem that cannot be ignored. Through the monitoring of pollutant discharge, the most direct pollution discharge situation can be obtained, which provides a scientific basis for environmental management, pollution source control, and environmental planning. [0003] Existing pollutant discharge monitoring technologies mainly include manual periodic monitoring and online monitoring. The manual monitoring method is to regularly arra...
