Introduction:

NB IoT meter application computer management, purchasing electricity first and then using it; The power usage can be limited within the rated current range (limited by the power supply department); SMS notification or automatic power-off prompt for users to purchase electricity; When the battery level is zero, the power will automatically trip and cut off; And it has certain anti-theft software design, etc. NB IoT meter is a representative of the new generation of wireless communication technology and low-power IoT technology, which has natural advantages when applied in the smart meter industry.

NB IoT meter technology advantages introduction: It can bring great convenience to remote meter reading, get rid of the traditional concentrator mode, save wiring construction, make the meter like a mobile phone, can be directly connected to the internet, and make energy consumption data easy to grasp anytime, anywhere.

NB IoT meter function introduction:

Measurement function

(1) It has a time-sharing metering function, and the active power is accumulated according to the corresponding time period, storing the total, peak, off peak, and valley power.

(2) Docking with third-party platforms, in addition to the data storage function of the electricity meter itself, the corresponding data will also be uploaded to the database through the NB-IOT module, and finally displayed in the form of data statistics on the power online service platform.

Remote cost control

(1) The electricity meter itself does not display electricity and electricity related information, and all data is uploaded to the server According to the electricity standards of State Grid Corporation of China, the final calculation is completed by the online power service system. In addition, the system platform also provides permission settings for users, property management, etc. to perform remote command operations, such as opening, closing, meter reading, etc.

Clock Time Periods and Rates

(1) This electric energy meter can be programmed with two sets of rate and time period tables, and automatically converted at the corresponding time. Each time period supports four rates, namely peak, flat, and valley. This electric energy meter also has ultra-high real-time temperature compensation

NB IoT meter price:

1. 5 (20) A: 150 yuan to 220 yuan;

2. 5 (30) A: 220 yuan to 300 yuan;

3. 10 (40) A: 320 yuan to 400 yuan;

4. 20 (80) A: 550 yuan to 750 yuan.

Therefore, NB IoT is a representative work of the new generation narrowband IoT transmission technology, which was developed by China as a standard and promoted globally. Compared to traditional 2G networks, the advantage lies in its outstanding features such as wide coverage, low power consumption, low cost, and strong signal. Especially suitable for low-frequency, fixed cycle data transmission application scenarios such as remote meter reading, environmental alarm, and status monitoring. At present, China Telecom and China Mobile have completed the nationwide NB IoT network construction.
