Urban Pipe Network Water Quality Monitoring System: Predicting the trend of water quality changes and providing decision-making basis for optimizing drainage systems. [Model recommendation: TH-GWS04, IoT integrated device, cloud based Tianhe support customized service] The urban pipe network water quality monitoring system integrates IoT, big data, artificial intelligence and other technologies to achieve accurate prediction of water quality change trends and provide scientific and reliable decision-making basis for optimizing drainage systems. When the monitoring data exceeds the preset threshold (such as pH<6.5 or>8.5, dissolved oxygen<5mg/L) or the change rate is abnormal (such as pH value dropping by 0.5 within 10 minutes), the system immediately triggers an alarm mechanism and notifies management personnel through SMS, APP push, email and other methods. By utilizing technologies such as LoRa, NB IoT, 4G/5G, etc., low-power and long-distance data transmission can be achieved, ensuring stable operation even in weak signal environments underground. Real time monitoring of the operation status of the drainage pipeline network, timely detection of problems such as waterlogging and sewage overflow, prevention of pollutants from directly entering natural water bodies through the pipeline network, and effective prevention of water pollution. The remote monitoring and data analysis functions reduce manpower and material costs, support management departments to quickly dispatch law enforcement personnel to the scene for disposal, and improve emergency response speed.

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
