The invention discloses a cellular communication Internet of things terminal data uploading method based on redis, wherein a redis storage system stores information such as ID, cellid and tac of terminal equipment; the method comprises the steps of analyzing the timing active uplink message of each intelligent terminal device through the large data of the platform background, extracting key device parameter information including a terminal ID, a base station cellid, a base station tac and the like, and realizing discrete calculation of the next active reporting time of each device by combining with redis, so that the risk of concurrent reporting of a large number of device nodes is staggered, the power consumption of the devices is reduced to the maximum extent, and load balancing is realized.

Description

Cellular communication Internet of things terminal data uploading method based on redis

Technical Field

The invention relates to a communication technology, in particular to a low-power-consumption basic data transmission technology of the Internet of things.

Background

The method is limited by the capacity limit of a base station (such as an NBIOT base station), the number of terminals allowed to be accessed by the base station is limited, for example, automatic meter reading gas meters need to upload data frequently, one NBIOT base station may be connected with tens of thousands of gas meters, when a large number of metering devices gather in a time period to send data, the instantaneous connection number of the accessed base station is particularly large, and after the moment, the base station is in an idle state, and the load of the base station in different time periods is too unbalanced. In the traditional cellular communication with high power consumption, such as mobile communication and other technologies, equipment can be continuously connected or switched to other base stations, but the field of the internet of things is communication based on low power consumption, and the traditional communication mode with high power consumption is not applicable, so that the situations that data reported by some meters is lost or data is delayed too long and the like occur in peak periods, and the data execution efficiency and the equipment power consumption are directly influenced.

Disclosure of Invention

The invention aims to provide a data internet of things data uploading method which staggers a large number of equipment nodes to be reported concurrently, has low equipment power consumption and balances load.

In order to achieve the purpose, the cellular communication internet of things terminal data uploading method based on redis is achieved, the device comprises a low-power-consumption base station based on the internet of things and internet of things terminal equipment communicated with the base station, and a redis storage system is further arranged and used for storing information such as ID (identity) of the terminal equipment, cellid of the base station, tac of the base station and the like; the data uploading method comprises the following processes:

1. the terminal equipment is awakened from the PSM state and actively reports metering and equipment state data;

2. the server receives an uplink data message of the equipment, and extracts information such as a terminal ID, a base station cellid, a base station tac and the like according to a message data analysis rule;

3, comparing the parameter with the base station information stored in the redis list, and if the record does not exist, executing the next step; if the data records exist and are consistent, no processing is performed; if the data records exist but are not consistent, deleting the previous base station information of the equipment, storing the released idle time period and then executing the next step;

4, obtaining the idle time period of the current base station of the equipment, if the idle time period does not exist, calculating the reasonable reporting time period of the equipment according to the equipment quantity of the current base station in a modulo manner, if the idle time period exists, directly taking the taken-out idle time period as the next reporting time of the equipment, and generating a configuration change instruction by the server according to the calculated reporting time and sending the configuration change instruction to the equipment;

5. and after receiving the configuration instruction of the server, the equipment resets and updates the active reporting time.

By adopting the scheme, the intelligent terminal equipment regularly and actively analyzes the uplink message through the large data of the platform background, extracts the parameter information of the key equipment, including the terminal ID, the base station cellid, the base station tac and the like, and realizes the discrete calculation of the next active reporting time of each equipment by combining with the redis, so that the risk of the concurrent reporting of a large number of equipment nodes is staggered, the power consumption of the equipment is maximally reduced, and the load balance is realized.

FIG. 1 is a flow chart of the present invention.

Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

The invention is realized by a List List and a sorted set ordered set of redis, which is a key-value storage system. The value types which support storage comprise string, list, set, zset and hash. These data types all support push/pop, add/remove, and intersect union and difference, and richer operations, and these operations are all atomic. The redis periodically writes updated data into a disk or writes modification operation into an additional recording file, and realizes master-slave synchronization on the basis of the updated data or the modification operation.

Discrete time calculation: 5 seconds apart, (table index value% 86400/5 at tac _ cid _ zset) × 5;

list tac _ cid _ del: storing the table terminal switching base station action under the base station; ordered set tac _ cid _ zset:

storing the table terminal information under the base station; hash table devices _ cids: and storing the information of the last secondary base station at the table end in the format of imei: tac _ cid.

Referring to fig. 1, the process of the present invention is as follows,

1. the equipment is awakened from a PSM state, namely a power saving Mode (PowerSaving Mode), and measurement and equipment state data are actively reported;

2. the platform receives an uplink data message of the equipment, and extracts equipment parameters such as imei, cellid, tac and the like according to a message data analysis rule

3. Comparing the parameter with the base station information stored in the devices _ cids list, and if the record does not exist, executing the next step; if the data records exist and are consistent, no processing is performed; if the data records exist but are inconsistent, taking out a fractional value S1 of the original tac _ cid _ zset, adding an S1imei _ del member to the position of the original tac _ cid _ zset, removing the imei member, adding an imei _ S1 element in the original tac _ cid _ del, generating an instruction, issuing the instruction, and executing the 5 th step;

4. taking out a first element imei _ score value of tac _ cid _ del, if the first element imei _ score value does not exist, acquiring the number of members of tac _ cid _ zset as score values, adding the members to the tac _ cid _ zset, if the tac _ cid _ del exists, resolving value, acquiring the score values, adding the members to the tac _ cid _ zset, deleting the occupied members in the score values, calculating the next reporting time of the equipment according to the index values of the table in the tac _ cid _ zset in a modulo mode, and generating and issuing instructions;

5. and after receiving the platform instruction, the equipment resets and updates the active reporting time.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
