The overall system plan uses three layers (data access layer, business logic layer, and user presentation layer) architecture. The three-tier architecture application program separates the user interface, business rules, and data access. The data access layer encapsulates access to the database. The user interface interacts with the business logic layer and the business logic layer interacts with the data access layer. Through multi-layer separation, good scalability, maintainability, reusability, and security are achieved. The B/SWeb technology application mode runs in LAN and Internet environments, which is easy to deploy and maintain. It is easy to use, has good scalability and flexible adaptability, has strong vitality, and is in line with current and future development trends.
The system has realized the collection and monitoring of key parameters such as operation parameters, equipment operation status, monitoring parameters, and pollution reduction calculation required for waste water and flue gas treatment facilities. The system has collected the water quality indicators and blower currents of the sewage treatment facilities in real time. , Blast volume, operating conditions of aeration equipment, dissolved oxygen concentration, sludge concentration, filter clogging rate and other data; and boiler load, temperature, flow, fan current and blade opening, oxidation fan in the operation of the flue gas desulfurization facility Sealed blower current, pump current, bypass opening, slurry pH, and smoke inlet and outlet process parameters such as sulphur dioxide, soot, and nitrogen oxide concentration eliminated the phenomenon of non-operation of the treatment facility. At the same time, the collected data is stored to a remote dedicated server, and the on-site process is displayed with the human-machine interface restored. The management department can log in, view, and supervise through the Internet and is an effective monitoring system for achieving pollution reduction targets.

1. Foreword With the accelerating process of our country's industrialization, people's living standards have been greatly improved, but, along with it, the environment in which human beings live has also suffered unprecedented destruction, free discharge of toxic fumes, and water sources. The water quality is seriously polluted, and the continuous deterioration of the living environment directly threatens human life safety! In order to improve the quality of the environment, the Chinese government has issued a number of energy-saving and emission-reduction regulations and established environmental monitoring mechanisms. However, due to the high operating costs of on-line monitoring equipment and the large amount of comparison monitoring and data validation, the reliability of monitoring data has been questioned. , There have been repeated occurrences of monitoring data fraud and monitoring errors. In order to improve environmental protection supervision measures, more attention is paid to whether the facilities are operated in environmental protection supervision and whether key parameters have operational records. Beijing 3D Force Control Technology uses advanced SCADA software and IoT technology to monitor environmental protection equipment and key operating parameters in real time. This not only makes supervision more powerful, but also makes supervision more intuitive and scientific.
