Rainwater and sewage drainage pipe network water quality monitoring system: optimizes pipe network design through flow monitoring data to avoid duplicate investment. [Model recommendation: TH-GWS03, IoT integrated device, customized service supported by Yunjing Tianhe] The rainwater and sewage drainage pipe network water quality monitoring system optimizes pipe network design through flow monitoring data to avoid duplicate investment. It can rely on high-precision flow monitoring equipment, scientific deployment plans, data-driven dynamic optimization strategies, and multi departmental collaboration mechanisms to achieve precise management of the entire life cycle of the pipe network. The flow monitoring equipment is installed at key nodes of the pipeline network to collect real-time data on the flow rate, velocity, liquid level, and other parameters of the drainage pipeline network. These data are important reflections of the operational status of the pipeline network, providing a foundation for subsequent optimization design. The collected data needs to be connected to various application systems through reliable data transmission networks. Wireless communication methods such as GPRS, 4G, 5G, as well as wired communication methods, can be used for data transmission to ensure real-time and accurate data. By monitoring the flow of the pipeline network in real-time, the load situation of the pipeline network can be accurately evaluated. When the flow rate at a monitoring point suddenly drops significantly, it may indicate pipeline blockage; An abnormal increase in flow may indicate pipeline leaks or illegal discharge. These pieces of information can help identify pipeline problems in a timely manner and provide a basis for optimizing pipeline design.

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.
