The purpose of the drainage pipe network water quality monitoring system is to ensure the efficient operation and balance of the drainage pipe network based on water quality indicators. 【 Model: TW-GWS06, IoT integrated equipment, Tianwei Environment supports customized services 】Against the backdrop of rapid urbanization and upgraded demand for water environment governance, the drainage network, as the core channel for urban sewage collection and transportation, has a direct impact on ecological security and public health in terms of operational efficiency and water quality balance. The drainage network water quality monitoring system is the "smart guardian" born to solve this problem. The system deploys multi parameter sensors at key nodes of the pipeline network to capture real-time dynamic changes in water quality indicators such as chemical oxygen demand, ammonia nitrogen, and heavy metal ions. Combined with data such as flow rate and velocity, it accurately identifies abnormal conditions such as pollution source invasion, sewage backflow, or sediment deposition in the pipeline network. When the water quality indicators deviate from the safety threshold, the system immediately triggers an early warning mechanism to provide pollution tracing and disposal suggestions for management personnel, avoiding local problems from evolving into systemic risks; At the same time, through long-term data accumulation and analysis, the zoning scheduling strategy of the pipeline network can be optimized to balance the drainage load of each region, prevent pipeline damage or sewage overflow caused by overload operation, and ultimately achieve efficient, stable, and sustainable operation of drainage facilities.

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.
