Date:2018-07-03   Source:   Browse:

NB-IoT intelligent remote transmission meter has been widely used as a popular product in most areas.NB-IoT intelligent remote transmission meter uses the IoT module to upload and manage data,and each module is a independent system,so that the Information transmission is more secure and reliable.

NB-IoT remote transmission smart meters have the advantages of low installation cost, no wiring, simple design, and small amount of construction,so it can adapt to need of the development of smart cities.The meter adopts NB-IoT wireless communication module to transmit data and no concentrator is needed,this enables it to provide more convenient and quick service for the debugging, installation,maintenance and repair of intelligent remote meter.

Our company's NB-IoT smart meter module has the advantages of wide network coverage, long transmission distance, and stable&reliable data transmission. It has the function of anti magnetic attack and interference, and don’t lose data when it is powered off, so that the incident of inaccurate metering will never occur.The module power supply adopts low-power sleeping technology,the battery life can reach more than 8 years. The NB-IoT remote transmission meter data has a regular reporting function of meter data. Users can use mobile APP or official website to pay water fees online, without having to go to the service hall to recharge,it serves the users better in a convenient and efficient way.

It  transmits and receives data wirelessly through NB-IoT module,and has characteristics of ultra-small size, ultra-low power consumption, strong performance and ultra-long transmission distance. The NB-IoT network has been widely covered, and the module's RF chip has the characteristics of high anti-interference, high reliability, and low power consumption.This module solves the problems that traditional design solutions cannot simultaneously take into account long-distance, anti-interference, low power consumption, wide signal coverage and ease of installation, and has become the best choice for reliable long-distance transmission applications.

Module function

Remote reading

Periodically and actively report the reading and status of the meter, and adopt the discrete reporting mechanism to prevent server congestion resulted from a large number of terminals reporting at the same time;

Remote valve control

Preset commands to close or open the valve remotely, with manual wake-up mode, trigger the water meter terminal to actively communicate with the server to receive valve control instructions, wake up by touch;

Prepaid

Support system, APP prepaid recharge, can support NB-IoT remote recharge and credit card recharge at the same time;Close the valve automatically when the fee is overdue.

Mechanical and LCD duel display

LCD can display accumulation, surplus, battery voltage, valve status and signal strength;

Warning system

Alarming in case of low battery voltage, abnormal measurement, magnetic attack, Pre-order quantity and prepaid amount reaches the limit ,etc. Smart water meters can set different emergency water consumption for different users;

Ladder water price

Water price can be set as tiered price according to user category and usage;

Ultra-long life combined battery

Standard ER26500 battery + SPC1520 battery capacitor combination power supply guarantees more than 6 years of use without replacement;

Data storage function

Can store data of no less than 31 days. When the storage data is full in the storage medium, the newly collected data automatically overwrites the earliest data, and the data within the storage period can be supplemented;

Internal / external antenna

Support internal / external antenna, stable and reliable signal, full coverage and no blind area;

Support multiple sampling modes

Support sampling methods such as photoelectric, Hall, reed switch, magnetic switch, ultrasonic etc, reading accuracy can reach 100%;

Reed switch failure detection

When a sampling reed switch fails, the meter will automatically upload a reed switch failure alarm.

Flexible upload frequency setting

The data upload cycle can be set to meet the management needs of different users. The uploaded data can include traffic that does not exceed one hour on the day (no less than 24 groups of data per day), and daily cumulative traffic, which is convenient for traffic monitoring;

Data resend and reissue mechanism

When one uploading fails, it will start multiple repeated uploading; If the re-uploading still fails, it will start the reissue mechanism. When it comes to the next uploading cycle,the data that failed to reissue will be resubmitted automatically.

The system adopts BS architecture

No client end installation required,just need browser login.Support both PC and mobile phone.
