Background:
Whether the water quality monitoring industry can develop stably and sustainably is an important foundation for national economic and social development. The regional and seasonal distribution of water resources in my country is seriously uneven. The availability of highly limited water resources is the responsibility of our entire society. The water conservancy department monitors and analyzes comprehensive indicators that can reflect water quality conditions such as water temperature, pH value, suspended solids, turbidity, flow velocity, and flow. Monitoring and forecasting flood disasters, water conservancy departments are responsible for forecasting water quality conditions and making decisions . The biggest feature of the water quality automatic monitoring system is that it can monitor water quality in a timely, accurate and effective manner.
However, the traditional hydrological monitoring technology is backward, the sampling capacity is insufficient, and information collection and processing are almost manual. Constrained by various conditions, the emergency response capability is not high, and the on-site monitoring management is weak. The rapid development of microelectronics technology, communication technology, computer technology, etc. has made us put forward higher requirements for hydrological work. Improve the level of information transmission and realize remote monitoring of water quality. It is of great significance for water quality monitoring to grasp the water quality status of major river basins in time and improve emergency monitoring capabilities.
Water quality monitoring plays an important role
With the growth of population and the development of industrial and agricultural production, residents' demand for water is increasing. The shortage of water resources and serious water pollution pose severe challenges to water quality monitoring. The automatic water quality monitoring system is based on comprehensive indicators and some specific items for monitoring water pollution. By setting up thousands of monitoring stations with continuous automatic monitoring instruments in a water system, the water pollution status of the area can be continuously and automatically monitored. At present, this type of automatic water quality monitoring system is mainly used to detect the water quality of a certain water area . In countries such as Europe and the United States, a large number of water quality analyzers with various parameters began to appear in the 1980s.
Japan, the United States, the Netherlands and the United Kingdom have used them on a considerable scale and have become very common. Thousands of wireless interconnected monitoring stations are set up in a certain area, and the monitoring stations are based on turbidity, conductivity, chemical oxygen demand, pH, Comprehensive indicators of water pollution such as water temperature are monitored. These monitoring stations are distributed by a central control system. Under the unified and coordinated work, the water pollution status in the designated area can be accurately measured in real time. Finally, the collected water quality information can be transmitted through carriers such as GPS global satellite positioning system. Although Japan has a small land area, it has developed earlier in the research and development of water quality monitoring systems. Their main advantage lies in the high degree of automation and relatively high degree of module integration.
The role of water quality monitoring system
IoT has a wide range of applications and can be used to monitor water quality to provide clean water and control the waste of natural resources. The best aspect of IoT is that it is easy to maintain and use, and because it is connected to the internet, it provides real-time control. Real-time control of the process can be achieved by using wireless sensors and sending data through the sensors to the cloud. The process will be efficient and in this way, manual monitoring costs can be eliminated using digital-based IoT systems. This will improve the quality and efficiency of management.
Water Quality Monitoring Solution
The water quality monitoring system collects the data of on-site water temperature, pH value, chemical oxygen demand, suspended solids, conductivity, dissolved oxygen and other parameters, and transmits the parameter data to the IoT cloud platform to realize real-time monitoring of the data of various devices on the spot. The user can view in real time through the computer webpage or mobile phone app, and can freely set the upper and lower limits of the standard value of each parameter. Water quality monitoring system solutions are widely used in rivers, lakes, reservoirs, fisheries, tap water, factories, water purification plants, wastewater treatment plants, swimming pools, aquaculture households, government water management, farms and other scenes.
