Ⅰ. Diagram of Smart Water Comprehensive Service System

Ⅱ. system diagram analysis

1. The entire system diagram is divided into three levels, from bottom to top are the terminal layer, the equipment bearing layer, and the data service layer.

2. The bottom layer is the terminal layer, which consists of various types of water meters, heat meters, sewage flow monitoring equipment, and water level monitoring equipment. Responsible for collecting original signals, calculating and storing water, heat, flow and other information.

3. The middle layer is the equipment bearing layer, which is mainly composed of "concentrator", "collector", "wireless gateway", "mobile ONENET", "Telecom Tianyi Cloud", and "Huawei Cloud". Responsible for collecting the data information of the terminal layer and uploading the data to the data service layer. This layer is oriented to a large number of terminal devices. Compared with the terminal directly connected to the data service layer, it can greatly improve the data service capability and significantly improve the stability and robustness of the system.

4. The top layer is the data service layer, which is mainly composed of three parts: "data center", "client", and "back-end management".

Data center: consists of several service programs, mainly including IoT data main service program, maintenance main service program (including product traceability), third-party data access service (1-N), business charging management service, operation information Comprehensive large-screen display services (big data analysis and visual display!!! This part can be customized at will without affecting the system architecture), third-party data push services (1-N).

Client: mainly for users. Its manifestation is WEB web version of water meter management (account opening, adding equipment, historical water use query, charging settlement, statistical analysis, etc.), mobile phone operating status display, user mobile phone payment, third-party data push (customize water meter data, fee status, etc.) Push to third parties), etc.

Back-end management terminal: the manager's headquarters for the smart water comprehensive service system, and the owner is the system service provider. Mainly realize the comprehensive large-screen display of meter operation information of the entire network, comprehensive management of the entire network of intelligent meters (equipment addition, deletion, recharge, user grouping, statistics, etc.), maintenance management (reporting amendments, maintenance progress, statistics, and faults) Remote analysis, product traceability, etc.)

Ⅲ. Advantages

Feature 1: Multi-level architecture design, capable of carrying massive equipment access management and monitoring. .

Feature 2: A data center is designed in the system, and the data of the entire network equipment is gathered here through the equipment bearer layer. It can realize big data analysis and visual display, with high stability and strong scalability.

Feature 3: Enhanced MBUS bus capability design, a single concentrator can carry up to 8 circuits, and each circuit has 200 water meters.

Feature 4: The use of the latest NB-IOT narrowband Internet of Things and 4G-Cat1 technology realizes the wireless transmission of all meters and is easy to install and use.
