Introduction: At present, China's water situation is very serious, and water meters as a measure of water consumption have an irreplaceable role in water resources and water management. Establish China's smart water meter technology standard system, promote and standardize the current and planned development products and technologies of China's water meter industry, promote economic and technical cooperation between production and manufacturing companies and related parties, enhance the communication between enterprises and users, and use water meters properly. Products and other aspects are of great significance.
China's water resources status and development trend of water meter technology China is a country with serious shortage of fresh water resources, and the per capita water resources share is less than 1/4 of the global average. It is one of 13 poor countries. At present, not only is there a lot of underground and surface water pollution in China, but also about 20% of the average quality drinking water leaks from the underground water supply network. This shows that the water situation in China is very serious. From the perspective of water management, accurate measurement and control of water consumption, scientific water use and water conservation, and the creation of a water-saving society are the only outlets China can currently choose. Water meter as a measure of water consumption has an irreplaceable role in water resources and water management.
The State Council's "Opinions on Implementing the Most Stringent Water Resources Management System" is based on the strategy and the overall situation of water resources. It requires that water measurement technology should be integrated with measurement, monitoring, and control, and be developed in the direction of high precision, intelligence, and systemization. Provide necessary technical support for the early realization of total water resources control throughout the country; the “China Water Conservation Technology Policy Outline†issued by the five ministries and commissions such as the National Development and Reform Commission also requires improving the accuracy and systematicness of water resources measurement and measurement and accelerating research and development. Metrology, measurement and control facilities and systems to better serve industrial and agricultural water and urban water supply systems.
At present, the application fields of water meter products have gradually expanded from the traditional drinking water metering services to areas such as drinking hot and cold water, heating water, irrigation water, intermediate water and sewage, industrial and fire water, etc.; represent the core of water measurement technology Some of the sensing technologies have also evolved from the original impeller and piston sensing methods to new types of flow sensing and signal processing technologies such as electromagnetic, ultrasonic, jet, and vortex; with automatic meter reading and prepaid water management Rapid advancement, water meter electromechanical conversion, data exchange, data processing, data transmission, network valve control and other technologies have also made considerable progress, water meter products have gradually moved from the terminal meter system integration; water resources measurement management model is also undergoing changes The development of a systematic and networked management model with simple measures of water consumption and water fee settlement as the main means of measurement, monitoring, and control; advanced metering facilities (AMI) and Internet of Things (IOT) technologies have become water measurement and Measure and control the main features of the next-generation technology. All in all, the water meter industry has become a gathering place for multi-technology disciplines covering machinery and electronics, sensing and signal processing, computers and communications, fluid mechanics, and materials.
The so-called "smart water meter" can be defined as: Accurate and reliable sensing and signal processing unit (currently also includes a very wide range of high-performance impeller or piston flow sensing mechanism and electromechanical conversion device), built-in embedded Computer systems and algorithms, various types of input-output interfaces, and/or electronically controlled actuators are platforms, with or partly having flow parameter detection, data processing (such as: filtering, computing, statistics, storage, self-school, etc.), data New electronic water meter products with functions such as communication, data display, controlled opening and closing of electronic control valves, and network access. Currently, smart water meter products that have been put into use mainly include: electronic remote water meter, prepaid IC card water meter, network valve water meter, numerical control water meter, water jet meter, ultrasonic water meter, and electromagnetic water meter with data transmission and valve control functions. Wait.
With the development of network technologies, especially the rise of the Internet of Things technology, a large number of new technologies related to smart water meters (terminals) have emerged. These technologies mainly include: wireless or wired networking technologies, network communication protocols and routing technologies, network access technologies, and data security. And reliability technology, data acquisition and management technology, automatic meter reading and water sales management system technology. Therefore, considering the technical standards of smart water meters, we should also take into account the development of closely related technologies.
