First, the system background
In the man-made sources, press the main target of pollution can be divided into air pollution, water pollution and soil pollution, among which air pollution and water pollution are two of the greatest impact on human life. The current national focus on the vast majority of provinces and key sources of pollution pollution control facilities have been built of different kinds of pollution-line monitoring system, including sewage chemical industry, power plant, chemical parks and key sewage treatment plants, sources close to the general re-deploy perception sensors, monitors, through different types of network-aware, the collected data is uploaded provincial / municipal environmental monitoring center, real-time online monitoring of the situation of major pollution emissions.
Second, the system overview
Factory pollution condition monitoring system refers to pollution, pollution control process, process emissions and other online data monitoring, collection, application. Through the establishment of relevant models, to achieve pollution control facilities approved operating conditions, to determine the authenticity of emissions data, while achieving pollution-line monitoring system, geographic information systems, management consulting to optimize the effective integration, providing data for the environmental review.
Third, the system principle
Plant sources condition monitoring system is divided into three parts, front-end data acquisition, wireless data transmission, monitoring and analysis system consisting of the rear end
1, the front end data collection: the front end of the water quality, gases, dust and other information collected by sensors local PM2.5, PM10, and water quality, gas and the like to be collected.
2, wireless data transmission: the wireless communication section by using the count information TD210 DTU 3G / 4G wireless transmission signal, the data pass-through or to the city, county monitoring platform using a special protocol format.
3, the back-end monitoring and analysis system: data transfer after the arrival platform, view real-time data via a data terminal or a large-screen and data analysis
System Topology
Fourth, the system function
1, craft show: Configuring dynamic simulation of real-time business process case
2, data query: data on the state of working conditions and field devices to monitor real-time queries, such as treatment facilities put into operation rate, pollutant removal efficiency, energy consumption, the main pollutants amount;
3, remote setting: When the platform can be remotely logger school, monitor reporting interval and daily data reporting time.
4, multi-curve comparison: comparison between the curve parameters day, month curves, correlation curves of different process parameters;
5, early warning and alarm: real-time early warning failure occurred during the production, control equipment running abnormal condition (alarm), and query alarm records;
6, the approved conditions: put into operation of pollution control facilities outage judgment process, it is an indispensable condition monitoring link, to provide more accurate data for the subsequent total amount approved;
7, the total amount of monitoring: the amount of information on working conditions carried out step by step system statistics show summary in accordance with provincial, municipal, corporate, pollution control facilities, combined with emissions targets for comparison and analysis.
8, statistical analysis: health record health and pollution facilities recorder, and manifested in the form of trends and logs.
