The 4G cellular modem is a data transmission terminal with high performance and low power consumption, which supports multiple communication protocols and data interfaces.It can be widely used in intelligent transportation, environmental monitoring, energy management and other fields. The 4G cellular modem has the following features:
(1) Support multiple communication protocols, such as GPRS, 3G, 4G, LoRa, etc., to realize remote wireless data transmission;
(2) Support multiple data interfaces, such as RS232, RS485, DI, DO, etc., to facilitate connection with various field devices;
(3) Highly integrated, with good anti-interference ability and stability, suitable for working in harsh environments.
The intelligent drainage solution based on 4G cellular modem mainly includes the following parts:
(1) On-site monitoring equipment: including water level sensor, flowmeter, water quality monitoring equipment, etc.Is used for collecting various data of the drainage system in real time;
(2) 4G cellular modem data transmission terminal: transmit the data collected by the field monitoring equipment to the background management system through wireless communication;
(3) a background management system, which realizes the real-time display, analysis and early warning of the field monitoring data,In order to support decision makers to carry out intelligent management of the drainage system.
(1) Equipment deployment: in the key parts of the drainage system,For example, water level sensors, flowmeters, water quality monitoring equipment and other monitoring equipment are installed at pumping stations, overflow outlets, inspection wells and other locations.At the same time, the 4G cellular modem data transmission terminal is connected with the field monitoring equipment to ensure real-time data transmission.
(2) Data transmission: that 4G cellular modem data transmission terminal transmit data through the supported communication protocol,The data collected by the field monitoring equipment is transmitted to the background management system in real time.In the process of data transmission, 4G cellular modem has the functions of automatic reconnection and data encryption.Ensure the stability and security of data transmission.
(3) Data analysis and processing: after the background management system receives the data transmitted by the 4G cellular modem,The data are analyzed and processed in real time, including water level change, flow statistics, water quality assessment, etc.At the same time, the system can also mine potential problems and rules through data mining and machine learning technologies.Provide a reference for decision makers.
(4) Early warning and alarm: The background management system implements the early warning and alarm functions according to the real-time monitoring data and the set threshold.Once abnormal conditions are found, such as high water level, excessive flow and deterioration of water quality, the system will notify the relevant personnel in time.Ensure the safe operation of the drainage system.
(5) Intelligent schedule and management: based on real-time monitor data and analysis results,The decision maker can dispatch and manage the drainage system intelligently, including the start and stop of pumping station, the control of drainage volume, the formulation of maintenance plan and so on.In addition, through long-term monitoring of the operation status of the drainage system, more reasonable drainage facilities planning and renovation programs can be formulated.
(1) Improve that management efficiency: monitoring the operation condition of the drainage system in real time,Decision makers can quickly grasp the actual situation of the drainage system and formulate timely and effective response measures.Avoid inefficient management caused by information asymmetry.
(2) Reduce operating costs: Real-time monitoring data and intelligent scheduling can optimize the operation mode of the drainage system.Reduce energy consumption and maintenance costs, and improve the service life of equipment.
(3) That safety of the drainage system is improve, namely the real-time early warning and alarm function can discover the abnormal condition of the drainage system in time,Prevent accidents and ensure the safe operation of the drainage system.
(4) It is beneficial to environmental protection: through real-time monitoring of water quality, pollution sources can be found in time.Effective measures should be taken to reduce environmental pressure and protect water resources.
Intelligent drainage solution based on 4G cellular modem data transmission terminal,The real-time monitoring and intelligent management of the drainage system are realized, and the management efficiency and safety of the drainage system are improved.It reduces the operation cost and provides strong support for the sustainable development of urban drainage system.With the continuous development of Internet of Things technology and artificial intelligence technology, this solution will have a wider application prospect in the future.
