Internet of things monitoring WiFi technology and control technology in the field of water quality
Water quality monitoring is an important means of water resources management and protection.
At present, China has entered a new period of Internet of Things development, and promoting the in-depth application and rapid development of Internet of Things and WiFi technology in the field of water quality monitoring is conducive to improving the informatization and intelligence level of China’s water quality monitoring.
Real-time online monitoring of water quality can realize continuous observation of water quality, timely obtain the water quality and overall change trend in the monitoring area, and provide data support and scientific basis for predicting and preventing water pollution and ecological damage.
In addition, the behavior and physiological characteristics of fish are closely related to the quality of the water environment, and assessing the water pollution level by observing the movement state of fish is also an important means of water quality monitoring.
Therefore, intelligent and efficient water quality monitoring systems play a vital role in real-time monitoring and effective governance of the water environment.
The water quality remote monitoring system adopts the Internet of Things architecture and WiFi technology, which can be divided into three parts from the functional structure, namely the perception layer, the network transmission layer and the application service layer.
Water quality remote monitoring system, Internet of things system architecture
In the sensing layer, water quality sensors are used to collect water quality information through various electrochemical formulas.
The water quality sensors used in the system developed in this book mainly include temperature sensors, dissolved oxygen sensors, turbidity sensors, pH sensors, conductivity sensors, salinity sensors, ammonia nitrogen sensors and COD sensors.
Most water quality sensors are electrochemical sensors that output as analog signals. Among them, some water quality sensors, such as pH sensors, dissolved oxygen sensors and ammonia nitrogen sensors, have weak water quality signals.
Therefore, it is necessary to design a conditioning circuit to amplify and condition the weak electrical signal.
At present, most water treatment circuits can convert weak electrical signals into current signals or voltage signals that can be measured directly by a multimeter.
Through the corresponding A/D conversion module and the corresponding water quality algorithm, the sensing data of the perception layer can be obtained, and then combined with WiFi technology.
In order to achieve comprehensive monitoring of water areas, water quality monitoring nodes are distributed in different locations of lakes or rivers, and the information collected by each node is processed and sent to the gateway node using short-distance communication technology, and the gateway node then uses long-distance WiFi transmission technology to send the water quality information of each node to the cloud platform.
At the network transmission layer, the water quality remote monitoring system designed in this book uses 5G network, WiFi7 technology and 4G network to remotely transmit the processed data to the host computer software and mobile phone APP application.
In the application service layer, a large amount of water quality data is mainly stored and processed.
According to the needs of users, design software systems with different functions to provide users with rich specific services.
At the application service layer, this book designs a configuration-based remote water quality monitoring software platform and a LabView-based water quality remote monitoring software platform, through which various water quality data real-time display, historical data query, over-standard alarm, remote control, prediction and early warning and other functions can be realized.
