      In order to solve the increasingly prominent problems of difficult to read meter and large amount of meter reading, water supply enterprises are constantly trying various new intelligent meter reading technology. From smart card reading to MBus automatic meter reading, there is still no ideal reading mode to solve many problems.

      Card table can not effectively monitor water use situation, so as to balance and dispatch water supply in time and effectively; The cable meter is complex in construction, high in cost, difficult to debug and heavy in maintenance; The stability of small wireless watch network is poor, and needs long-term maintenance in the later period, so it is difficult to balance power consumption and real-time performance. With the advent of Nb IOT narrow band Internet of things technology, smart meter reading technology has seen the dawn of victory. The water meter industry also quickly focuses on the Nb IOT remote water meter, a new technology.

      Due to the difficulties of real-time monitoring, complex construction, high cost and poor communication stability in traditional intelligent water meter reading, the emergence of Nb IOT narrow-band Internet of things technology will fundamentally change this situation. NB -- IOT technology has the characteristics of wide coverage, high reliability, high security, low cost and low power consumption. In the field of intelligent water meter, it can not only reduce the cost of meter reading, but also realize the intelligent and big data management of water meter management, which has very important practical application value

      Nb-iot intelligent water meter system is mainly composed of water meter with Nb IOT communication module, Nb IOT communication base station, IOT cloud platform, service server, client management software, etc. Each household is equipped with an intelligent water meter with Nb IOT technology. After it is put into operation, the intelligent water meter will search the nearby NB IOT communication base station and register with the IOT cloud platform. The cloud platform will know the data reporting and receiving ability of the device. The water data of the intelligent water meter can be uploaded to the IOT cloud platform through the communication base station, You can also receive control data messages from the cloud platform
      The client management software obtains the real-time data of residents' water use from the cloud platform through the business server, monitors the real-time water use situation of each resident, and the client can also control the real-time ladder price adjustment of residents' water use, customize the data copying strategy of the business server, and push the monthly water use situation and deduction situation to the residents.

      Under the background of rapid growth of Nb IOT, the close combination of IOT technology and water supply business will continue to be the development trend. By promoting the new business model of combining water meter with Internet of things, cloud computing and big data, the water industry will produce inestimable market value in the future.

      At present, the number of Nb IOT water meters installed and used by Jinquan group has exceeded one million, which has been in the forefront of various vertical industries!
