NB-IoT, also known as narrowband Internet of Things technology, is a key access technology in the field of IoT. Compared with wireless Internet of Things technology, NB-IoT has significant advantages such as low power consumption, large capacity, high stability and deep coverage. It can be widely used in intelligent meter reading, intelligent parking, intelligent logistics and other fields.
 
In order to promote the application of NB-IoT in the field of subdivision, in 2017, Ministry of Industry and Information Technology issued the Notice of Fully Promoting the Construction and Development of NB-IoT in Mobile Internet of Things, which requires that the total number of NB-IoT connections exceed 600 million yuan by 2020.
 
Take NB-IoT intelligent water meter as an example. With the continuous maturity of NB-IoT technology application, the traditional water industry has been affected by the strong momentum of the Internet of Things, together with many difficulties and painful points in its own existence, which has attracted much attention in the wisdom transformation of the water industry.
 
As a terminal data acquisition equipment, water meters connect thousands of households. In order to collect data, the most original method of meter reading is to read the meter at home by the meter reader and to collect statistical data. With the development of society, manual meter reading has many drawbacks, such as low efficiency, high labor cost, error-prone recording data, difficult maintenance and management, etc.
 
So GPRS remote meter reading came into being. It solves a series of problems of manual meter reading. It is more advanced, more efficient and safer than manual meter reading technology. However, GPRS remote meter reading also has some shortcomings, which make it impossible to popularize in a large area, such as small user capacity, high power consumption, poor signal and so on.
 
The remote meter reading based on NB-IoT technology solves this problem very well. NB-IoT remote meter reading inherits GPRS remote meter reading function and also has huge capacity. The same base station communication user capacity is 10 times of GPRS remote meter reading; lower power consumption, the standby time of NB-IoT terminal module can be long under the same use environment. More than ten years; new technology has stronger signal coverage (indoor and basement coverage).
 
With the maturity and perfection of flow measurement technology, network communication technology, automatic control technology, GIS geographic information technology, micro-power supply technology and cloud computing technology, NB-IoT intelligent water meter has become a hot spot and inevitable development in the intelligent water market.
 
At present, there are many domestic water supply companies that choose to use NB-IoT intelligent water meter. In addition, with the policy of "one household, one table", "step billing", "multi-table integration" and the formation of smart city tuyeres in China, a window of wisdom has been opened for traditional water meter manufacturers, and the NB-IoT smart water meter will usher in a broad space for development.
 
"The 13th Five-Year Plan Outline for the Development of Water Meter Industry in China" points out that during the 13th Five-Year Plan period, the sales revenue of intelligent water meters (including intelligent application systems) in China accounted for 40% of the total water meter sales, and it is expected that more than 150 million intelligent water meters will be added during the 13th Five-Year Plan period, with the corresponding industrial scale exceeding 40 billion yuan.
 
There is no doubt that the direction of the NB-IoT intelligent water meter is determined, and the benefits are obvious. However, the cost of NB-IoT intelligent water meter is also increasing due to the adoption of various advanced technologies.
 
Water meter enterprises should embody the value of NB-IoT intelligent water meter by providing more value-added functions (such as leak alarm, abnormal water alarm, special business scenarios, etc.), so as to be more widely accepted by water supply enterprises and society, rather than simply solving the problem of meter reading at home.
 
It is believed that under the influence of intelligent water, the development prospects of NB-IoT intelligent water meter will be very broad.
