China's smart water meter is currently lagging behind
· Intelligent water meters are limited by water environment and technical standards. The conditions for widespread promotion and use are still immature due to many factors such as the installation environment and measuring medium. Water meters, like smart meters, are difficult to measure accurately. Intelligent water meters operate in wet and rusty environments for a long time, and electronic control modules are prone to failure. The detection criteria for water quality, surface water and groundwater in the north and south, and the water meter diameter, installation method and installation environment are not the same. Therefore, it is impossible to establish a unified technical route and standard. The smart meter does not show a high level in the physical layer or in the protocol layer. Unification affects the coverage of smart meters.
Intelligent water meters have high technical barriers. In terms of wireless communications, there are network access cards for electricity meters, and each meter's communication is subject to a perfect monitoring system. No one is responsible for the meter's access to the network, and the concentrator has no place to monitor; in addition, the water meter The radio frequency performance of its own technology is not stable, and the communication frequency of the external environment is in short supply. There is no unified communication network. Each enterprise's water meter can only communicate with its own system and cannot form a large-scale wireless meter reading system. Affected the implementation of the copy of the four tables. Even through the introduction of foreign advanced technology to rapidly realize the intelligence of water meters, the problems of tap water quality in China will still cause the electronic control module to operate in wet and rusty environments, and it is easy to malfunction.
Therefore, China must establish its own intelligent water meter technology standard system as soon as possible to strengthen the design and research and development of high-performance ultrasonic water meters, remote water meters, Internet of things, water meters and other products, guide the orderly development of industries and technological progress, and quickly keep up with advanced smart meters. The pace of industrial development.
· The water company is decentralized, and the water meter company has difficulties in research and development. The downstream of the smart water meter is mainly water companies, and there are many water companies in China, which are highly decentralized.
At present, there are more than 4,000 water companies in China that have relatively independent management. Although they have the right to purchase, most of the water plants are not well-funded. Most of the budget is spent on the maintenance of the water supply network. It is difficult to have sufficient funds to purchase and install smart water meters. The system, which also largely curbed the enthusiasm of water meter companies to develop smart products.
At present, there are more than 600 water meter manufacturers in the country, and their scales are mostly limited. It is difficult to allocate funds from the budget or to finance the use of new technologies. Even if the country actively guides the implementation of the ladder water price to promote the development of the smart meter industry, due to the high technical barriers of smart water meters, a large number of water meter companies have tried it.
· Large-scale water meter companies will eventually come to the fore, leading the trend of the industry highly dispersed management system for the meter industry's impact is high regional procurement barriers, water meter companies with low industry concentration, but with the community's demand for intelligent water meters and policy support, Water meters will quickly develop in a more intelligent direction. Small companies will gradually lose their market competition due to difficulties in breaking through technical barriers. Large-scale water meter companies are expected to highlight their scale advantages, gradually increase their position and market share in the industry, and obtain more More water company's favor.
Intelligent meter powerful, strong applicability
Intelligent water meter can realize centralized reading, remote reading and real-time reading. The data is objective and accurate. It can be read in real time and monitored in real time. It can also monitor the water quality and water pressure to facilitate water company data analysis. And to strengthen water management, can also provide smart fees and other management and services, integration of smart city construction to solve the mechanical meter manual reading efficiency is low, copy data errors, tap water company long-term funding operations and other conditions.
Due to leaks, low measurement accuracy, and management loopholes, domestic water companies have relatively large losses in production and sales. If smart meters are installed on major nodes, they can save water resources and reduce production and sales. According to the national average annual water supply of 600 billion tons, the average price of water supply is 2 yuan/ton, after the intelligent water meter reconstruction can reduce the estimated production and sales margin of about 5%, and the market space can be released every year 60 billion yuan.
The smart grid is the basis for achieving intelligent water meters. The use of smart grids has completely solved the problem of signal transmission and energy supply for smart water meters. In terms of signal transmission, to solve the problem of user networking and the last kilometer problem of the water meter of the terminal, the effective integration of the water meter and the cloud platform is fully realized; in terms of water management, remote valve control, water quality and water pressure detection, and fault detection are realized. , abnormal alarms and other intelligent water management functions.
At present, China's smart water meters mainly rely on low-end IC card water meters, and wireless remote smart water meters account for less than 20% of the entire smart water meter market. With the gradual increase in the penetration rate of smart water meters and the increase in water demand, the proportion of wireless remote water meters will gradually increase.
NB-IoT technology will lead the revolutionary progress of smart water meters
Because the water meter's placement environment is usually in a dark and damp hidden environment, and can not be external power supply, currently occupying the market-leading M-Bus bus communication and wireless communication technology in the coverage and power consumption can not meet the requirements of the automatic reporting data of the water meter . The NB-IoT is suitable for the low-power wide area network market, and it is expected to achieve the strict requirements of low-power and low-cost Internet of Things (IoT) smart meters and terminals, wide coverage, no ad hoc network, and easy network access.
At the end of 2015, Huawei, Vodafone, and u-blox jointly announced that they completed testing of pre-standard NB-IoT solutions based on commercial networks in Spain: the water meter was connected to the water meter by embedding u-blox modules supporting NB-IoT technology. Into the mobile network, so as to achieve remote meter reading business. In May 2016, Shenzhen Water signed a strategic cooperation agreement with Huawei and China Telecom, and will use the NB-IoT communication protocol to carry out pilot work on smart water.
China's water meter industry has listed NB-IoT wireless network access technology as an important application technology for China's water meter industry during the “Thirteenth Five-Year Plan†period, and plans to establish a “Wireless Communication Technology Working Group†within the water meter industry to formulate relevant standards and technologies. The solution is to carry out the pilot work before large-scale promotion, and promote the application of NB-IoT technology in the smart water supply business.
The application of NB-IoT technology will greatly reduce the cost of smart water meters. At present, the unit price of common mechanical water meters is about 50 yuan, and that of smart water meters is 250-300 yuan. The Internet of things meter needs to add 30 yuan to the cost of smart meters, 8 years of communication costs 48 yuan (6 yuan per year), and the price is about 300-350 yuan. Left and right, lower than the current advanced wireless remote meter communication module. Since NB-IoT is not based on traffic consumption, data reporting cycles in smart meter applications are long and the consumption of traffic is small, so the traffic costs are also reduced. It is expected that the unit price of a new generation Internet of Things meter using communication technology can be reduced to 200-250 yuan, the battery life is 10-15 years, and the battery life is more advantageous in 2 years.
Smart meter market has broad prospects and rapid growth
In 2015, China produced 70 million water meters, including 15 million smart water meters, 10 million water meters, and 60 million domestic sales. Although the current domestic real estate market has reached a stable level, the transformation of squatter settlements is also a huge market. With the continuous improvement of technology and the evolution of smart cities, the smart meter industry will develop steadily.
Before 2016, the output of smart water meters has been growing at a rate of nearly 20%. It is expected that the new generation of Internet of Things and NB-IoT smart meters will achieve mass production within 2-3 years, which will greatly satisfy the market demand. “The Outline of the 13th Five-Year Development Plan for China's Water Meter Industry†pointed out that during the “13th Five-Year Plan†period, the sales revenue of smart water meters (including smart application systems) should reach 40% of the total sales of water meters, accompanied by favorable policies, and smart water meters. The market scale will also steadily increase. It is expected that the growth rate will reach 28%. By 2020, the penetration rate of smart water meters will approach 45%, and the annual shipment volume will reach 45 million units. According to the prediction of the increase in penetration rate and the estimated growth rate of sales revenue, it is assumed that the future 40%-50% of the new water meter demand will be a smart water meter, which will be calculated according to China’s current estimated 450 million home users and smart water meter price of 270 yuan/set. In the five years, China will add more than 150 million smart water meters, and the corresponding scale will reach more than 40 billion yuan, which will achieve a significant increase compared with the current market scale of 5 billion yuan per year.
