Problems solved by technology

However, although NB-IoT has many advantages compared with existing technologies, it still encounters problems in some aspects. For example, for smart gas meters with high concentration, the number of smart gas meters directly connected to base stations is huge, When the smart gas meters need to report data, because most of the reporting time is preset, it is easy to form a situation where a large number of smart gas meters report data at the same time, resulting in channel congestion of the base station
Compared with existing technologies, there is no good solution

Embodiment 1

[0033] A method for dynamically selecting data reporting time, such as figure 1 shown, including the following steps:

[0034] S1: The control unit reads the preset reporting time T, and reports the data when the reporting time is reached; if the reporting is successful, the method ends, and if the reporting fails, step S2 is executed;

[0035] S2: The control unit reads the preset reporting interval reference time t and adjustment section t 0 , at (t-t 0 ,t+t 0 ) randomly select an interval time t' and start timing, when the timing time reaches t', the next data report will be performed, and the t>t 0 ;

[0036] S3: The control unit judges: if the report is successful, execute step S4, and if the report fails, return to execute S2;

[0037] S4: Record the time of successful reporting and set it as the preset reporting time T, and the method ends.

[0038] Since the number of smart gas meters based on NB-IoT is very large and the installation is usually relatively concen...

Embodiment 2

[0044] A kind of narrow-band Internet of things smart gas meter, such as figure 2 shown, including:

[0045] The control unit 1 is used to read the preset reporting time T from the storage module 2 and send the data to the NB-IoT communication module 4 after receiving the time-out signal from the clock module 3; read from the storage module 2 after the report fails Report interval reference time t and adjustment period t 0 , and from (t-t 0 ,t+t 0 ) randomly selects an interval time t' in the interval, and triggers the clock module 3 to time; it is used to send the data to the NB-IoT communication module 4 after receiving the signal of the end of t' timing; it is used to report the data when the data report is successful The successful time is written into the storage module 2 as the preset reporting time T;

[0046] Storage module 2, used to save the preset reporting time T, the reporting interval reference time t and the adjustment section t 0 ;

[0047] Clock module ...

Embodiment 3

[0053] A kind of narrow-band Internet of things smart gas meter, such as figure 2 shown, including:

[0054] The control unit 1 is used to read the preset reporting time T from the storage module 2 and send the data to the NB-IoT communication module 4 after receiving the time-out signal from the clock module 3; read from the storage module 2 after the report fails Report interval reference time t and adjustment period t 0 , and from (t-t 0 ,t+t 0 ) randomly selects an interval time t' in the interval, and triggers the clock module 3 to time; after receiving the signal that the t' time ends, the data is sent to the NB-IoT communication module 4; when the data is successfully reported, the time of successful reporting is used as The preset reporting time T is written into the storage module 2; it is used to trigger the alarm 6 when the reporting failure reaches the preset number of times;

[0055] Storage module 2, used to save the preset reporting time T, the reporting in...

Abstract

The invention discloses a data report time dynamic selection method and a narrow-band Internet of Things based intelligent gas meter. The method includes: S1, reading preset report time T by a controlunit, and performing data reporting when report time is reached; if reporting fails, executing the step S2; S2, reading preset report interval reference time t and adjustment section t0 by the control unit, randomly selecting interval time t' in a section of (t-t0, t+t0), starting timing, and performing next data reporting when timing time reaches t', wherein t is larger than t0; S3, enabling thecontrol unit to judge, executing the step S4 if reporting is successful, and returning to execute S2 if reporting fails; S4, recording reporting success time to set as the preset report time T. Extraequipment is avoided, dynamic balance of data report time distribution is realized, and low cost, simplicity in operation and high reliability are realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent gas meters, and in particular relates to a method for dynamically selecting data reporting time and an intelligent gas meter of the narrowband Internet of Things. Background technique [0002] With the rapid development of smart gas meters, traditional communication methods such as GPRS have long been unable to meet the needs of the times, and the development and popularization of narrowband Internet of Things (NB-IoT) in the field of smart meters is getting faster and faster. NB-IoT has become the technology of choice for the new generation of smart gas meters due to its many advantages such as wide coverage, large number of connections, low power consumption, and low cost. However, although NB-IoT has many advantages compared with existing technologies, it still encounters problems in some aspects. For example, for smart gas meters with high concentration, the number of smart gas meters dire...
