Product Overview
NB-loT Internet of Things is characterized by strong links, high coverage, low power consumption,
and low cost. It is also called the "Narrowband Internet of Things". Because of its very low communicationpower consumption, the NB-loT wireless remote water meter can continue to work for more than six yearswithout changing the battery. Using the NB-loT wireless remote water meter can realize the wireless
automatic meter reading function. At the same time every day, the NB-loT module will collect andautomatically transmit the water consumption data of each household to the management platform.Perform statistical analysis and charge for the water consumption of water meters in the managementarea.
The NB-loT system consists of the NB-loT management system platform, base stations, and loT watermeters (NB-loT). The system has a high degree of automation, can monitor the operation and consumption of the meter at any time, and has a wide range of applications.
Technical Features
1. High security
Two-way authentication;
The air interface is strictly encrypted;
Dedicated channel, no other signal interference, and more stable data transmission
2. Wide coverage
20db gain, coding gain;
lmproved narrowband power spectrum density;
lt has a retransmission mechanism when automatic transmission fails;
China Mobile/Telecom's NB-loT base station has achieved full coverage
3.Low power consumption
Battery life of more than 6 years (1 day/1 communication);
Simplify protocol and chip micro power consumption;
High functional efficiency;
Short transmission/reception time;
4.Big connection
High frequency increase efficiency;
Small packet data sending characteristics;
Very low activation ratio of the terminal
5.Product implementation standards
ISO9001; GB/T778.1.2.3-2007; JG 162-2009;CJ/T 188-2004.
Product Features
1.Periodic report: report the 24 hours data of the previous day, and the data includes daily freezinginformation.
2.High-frequency periodic reporting: The sending frequency can be set or changed through the platform ,and the minimum reporting period is every hour
3.Intensive data collection:4 hours from the set start time, one point every 5 minutes, a total of 48 points of accumulated flow.
4.Data repackaging: When data reporting is unsuccessful, the data will be automatically re-reported inthe next reporting period, and data within the effective storage range can be re-reported.
5. Discrete setting: Discrete the reported time points randomly through the program, the minimumestimated length is 10S, and the default is 0 to 8 points to ensure that the communication basestation will not be blocked by a large amount of data in a short time.
6.Remote setting of parameters: Through the near-end handheld infrared reading device and
communicating with the management platform, setting IP, port and other parameters
7. Alarm function: When the battery undervoltage is lower than the predetermined value, the platform will automatically alarm to remind the administrator
8. Time proofreading: When the data is reported periodically, the clock will be automatically proofread with the platform to ensure the accuracy of the time
Software Advantages
1. Power supply: DC 3.6V;
2.Battery capacity and life: 8500mAh can be used for more than 6 years (automatically uploaded once a day)
3.Static power consumption: ≤10uA Communication power consumption: ≤18uA
4. Working temperature: cold water meter: (0.1~30)℃ hot water meter: (0.1~90)°℃;
5.Working pressure: s1.OMPa;
6. Pressure loss:≤o.063MPa;
7.Shell protection grade: IP68;
8.Sensitivity level of flow profile: U10/D59.
9.Installation environment: Class B;
10.Electromagnetic environment: E1- residential, commercial and light industry;
The platform adopts the B/S architecture design method, no need to install the client, in the place whereyou can access the Internet,you can log in to the system by directly entering the URL,which is convenient and fast.
1.Perfect remote parameter setting and management control
2.Multiple billing methods and types, a variety of table format output, and can provide user customizationfunctions
3. With user password protection, multi-level operation management, high socurity and confidentiality
4. Data analysis function, daily statistics,monthly statistics, and statistical report output
5. Diversified data interface docking can be seamlessly docked with the current software management platform of the water management department
Common faults & causes
Button on flange are broken and damaged. If the spacing is too small, the water meter cannot be installed. If the pipelines at both ends of the water meter are not on the same axis, the pipeline should be corrected
dripping and running water in the pipeline behind the water meter.
3.When there is no data upload on the platform, the administrator needs to go to the site to check the troubleshooting.
Note: The battery of the water meter should be replaced by a professional person, and the user should not replace it by himself.
