Brief introduction
The NB-loT system consists of the NB-loT management system platform, base stations, and loT water meters (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.
Product Features
1.Periodic report: report the 24 hours data of the previous day, and the data includes daily freezing information.
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 in the 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 minimum estimated length is 10S, and the default is 0 to 8 points to ensure that the communication base station 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
