Water is the source of human life, but with urban development, water pollution has become increasingly serious. Water resource supervision and management have become a major challenge for urban development. Untimely water quality monitoring and flood warnings directly affect people's livelihoods. The development of the Internet of Things (IoT) for water management can solve these problems in a very timely and accurate manner.
In recent years, with social development, the concept of smart cities has achieved sustainable development. The continuous advancement of IoT technology has led to its widespread application across various industries. The advancement of smart cities has highlighted the importance of water management. With the introduction of the smart water management concept and the in-depth application of information technologies such as big data, cloud computing, and IoT, significant progress has been made in water management. So, how is IoT technology applied in water management? Let's take a look.
I. Application in intelligent wastewater treatment systems
Wastewater treatment is a crucial part of water management. The wastewater treatment process is an extremely complex biochemical process, making it very difficult to maintain stable operation over the long term. Its operation and management are mostly carried out by professionals with years of experience. This requires management and operation personnel to possess highly specialized industry knowledge and be present on-site at all times to ensure immediate response in case of emergencies. The main functions of an IoT-based intelligent wastewater treatment system are as follows:
1. The Internet of Things (IoT) technology uses information sensing devices such as RFID, infrared sensors, GPS, and laser scanners to monitor the key indicators of the system in real time and upload them to the central processing system for analysis and storage. Once abnormal data is detected, an alarm will be generated, and based on the analysis of historical experience data, diagnostic results will be output and instructions will be automatically sent to the system for repair and debugging. If manual intervention is required, information will be automatically pushed to the relevant management personnel.
2. The intelligent wastewater treatment system will collect various data from each wastewater treatment facility in real time, perform calculations and analyses based on the established model, thereby determining the system's operating status and predicting future operational trends. It will automatically adjust the dosing frequency and dosage according to actual conditions, thus controlling operating costs within a certain range. Furthermore, it can predict the demand for various operating costs in the future, reminding managers to allocate resources in a timely manner.
II. Application in Smart Water Management System
The smart water management system utilizes technologies such as cloud computing, the Internet of Things (IoT), and hardware/software integration to integrate all relevant systems in water management. This enables information exchange, sharing, parameter correlation, and interactive linkage among these systems, allowing for independent operation while maintaining symbiosis. Each system can operate independently while ensuring seamless data and information exchange; simultaneously, it accumulates parameters and generates routine analytical reports based on actual operational conditions, achieving a smart platform technical structure. The main functions of the IoT-based smart water management system are as follows:
1. GIS system
To conduct water supply scheduling more scientifically and accurately, improve management, service quality and efficiency, monitor the pressure, flow and water quality of water supply pipelines, and achieve automated water supply management.
2. SCADA System
This is a data acquisition and monitoring control system. The system integrates pipeline pressure monitoring, flow meter monitoring, large-diameter water meter operation monitoring, water quality monitoring, pump station monitoring, water plant monitoring, and valve regulation into one system. It provides stronger basic data and technical support for water companies' high-level decision-making and optimized scheduling, such as water supply planning, rational operation, pipe burst early warning, leakage analysis, and emergency services. It helps water companies improve management operations, detect water supply anomalies in a timely manner, and reduce operation and maintenance costs.
Automation, intelligence, and control systems are the hallmarks of IoT technology and the main methods driving the intelligentization of various industries. It is believed that in the near future, IoT technology will have even more applications and bring about more changes.
