Urban Pipe Network Water Quality Monitoring System: A Core Tool for Ensuring Urban Water Supply Safety and Improving Drainage Management Efficiency [Model Recommendation: TH-GWS03, IoT Integrated Device, Cloud Environment Tianhe Support Customized Service] As a core tool for ensuring urban water supply safety and improving drainage management efficiency, the urban pipe network water quality monitoring system integrates multi parameter sensors, IoT communication, big data analysis, and intelligent warning technology to achieve real-time perception, dynamic regulation, and scientific decision-making of urban water supply and drainage networks. Support multi-level data relay and breakpoint continuation to ensure data integrity in complex underground pipeline environments. Integrate big data analysis and machine learning algorithms to clean, mine, and model massive water quality data, generate water quality change trend charts, pollution warning reports, and pipeline health assessment reports. The system collects water quality data at a minute level frequency. When the parameters exceed the standard, it automatically triggers SMS, email, APP push or sound and light alarms, and links emergency equipment (such as dosing devices and sewage gates). By analyzing the water quality data of pipeline nodes, identifying hidden dangers such as pipeline corrosion, scaling, and leakage, evaluating the remaining life of the pipeline network, and providing a basis for maintenance and renovation.

1、 Product Overview

The low-power collection microsystem of the pipeline network directly transmits JSON data to the designated server through 4G and supports MQTT protocol transmission.

Other formats of data are transmitted to our company's cloud platform via 4G. Our company provides an HTTP interface, and other platforms obtain data through this interface.

The built-in 8GB TF card can store the read data in the memory card.

The baud rate of each serial port communication can be modified through commands, and the required sensor parameters can also be added, modified, and deleted through commands.

2、 Functional Features

1. Equipped with a built-in 3.6V 152AH lithium battery, ensuring continuous operation for 3 years.

2. IP68 waterproof rating, no need to worry about pipeline swelling.

3. There are two 485 interfaces, one for device configuration and one for sensor reading

4. Supports Modbus RTU sensor reading and data saving function

5. The serial port baud rate can be independently modified

6. The sensor communication port supports a maximum of 32 nodes
