Main technical content:

(1) Basic principles

"MTC-3W Water Treatment Automation System" is a comprehensive application technology that integrates physical, chemical and biological technology, building technology, mechanical and electrical control technology, electronics, measuring instrument technology, computer network communication technology and computer automation control technology. The network topology diagram is as follows:

(2) Technical advantages

1.  Based on a hierarchical and distributed structure, it has energy-saving optimized operation control technology combined with process mechanisms, improving the production management level of my country's sewage operation industry.

2.  Intelligent processing of "remote signaling YX, telemetry YC, remote control YK, remote control YT, remote pulse YM, remote viewing YS" signals is realized, and satellite GPS or Beidou time correction synchronization system is used to enable the equipment operating conditions and effluent water quality of each factory area to be real-time comprehensive monitoring, analysis and control.

3.  It has the remote operation mode function of unmanned stations in the water treatment plant. Remote unmanned duty can be realized through seamless access to wireless remote monitoring sites such as GPRS, 3G, and WIFI, which greatly reduces the number of operation and maintenance personnel and reduces operating costs.

4.  Real-time monitoring and preset simulation online water quality instruments and operating equipment to realize the recording, analysis, and processing of various data across the plant, and provide management decision-making services to business leaders in a timely manner.

5.  It can provide intelligent interfaces with data collection and control equipment, support multiple interfaces and protocol development, and support cross-platform; data storage supports multi-machine redundancy; data applications support WEB publishing, mobile APP monitoring, professional simulation and optimization of operations, technical applications such as decision-making, equipment maintenance and management.
