Description
Technical Field
The invention belongs to the field of communication of the Internet of things, and particularly relates to an intelligent ID distribution method for equipment of the Internet of things.
Background
In the prior art, an internet of things device ID allocation method is as follows: (1) a networking module of the Internet of things equipment is distributed with a unique IMEI code, each piece of networking equipment is registered on a server by using the IMEI code to acquire the authority of accessing the server, and meanwhile, a server side distributes a unique equipment ID to the equipment newly registered with the IMEI code and sends the unique equipment ID after the equipment side is networked; (2) and after the newly-accessed Internet of things equipment is started, the newly-accessed Internet of things equipment is connected with the server, and the server issues the equipment ID after authentication. (3) And the Internet of things equipment receives the ID number and stores the ID number in storage equipment such as the E2PROM and the like.
The method for distributing the ID of the equipment of the Internet of things has the following problems: (1) if the networking module of the existing network equipment fails, the IMEI code changes after the new networking module is replaced, the IMEI code needs to be registered again at the server side, and meanwhile, the server side can allocate an equipment ID to the equipment again. And after the equipment with the networking module replaced is networked, receiving a new equipment ID and writing the new equipment ID into the E2 PROM. In this way, the same device corresponds to 2 device IDs in the server-side database, which causes confusion when maintaining data uploaded by the device. (2) If the E2PROM of the equipment of the Internet of things fails and is replaced, the ID information of the equipment is lost, so that the server cannot judge that the data uploaded by the equipment during working belongs to the equipment.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1, the invention discloses an intelligent distribution method for an ID of an internet of things device, the internet of things device includes a networking module and an E2PROM, the networking module is distributed with a unique IMEI code when leaving a factory, the E2PROM is used for storing a device ID, and the intelligent distribution method for the ID of the internet of things device includes the following steps:
s10, writing default equipment IDs in the E2PROM of each equipment in a unified mode when the equipment leaves a factory at the equipment end of the Internet of things;
s20, registering the unique IMEI code of each normally working device at the server end to acquire networking authority;
s30, after the Internet of things equipment terminal is started, the equipment terminal reads the equipment ID of the E2PROM and sends an equipment ID distribution application to the server when the judgment condition is met;
s40, after receiving the equipment ID distribution application and the IMEI code corresponding to the equipment, the server compares and processes the IMEI code with the equipment database;
s50, when the Internet of things device uploads data in use, the data packet header contains the device ID and the IMEI code, and the server reads the IMEI code and the device ID simultaneously, and compares and processes the IMEI code and the device ID with the device database.
In a specific embodiment, the networking module comprises a 2G module, a 3G module, a 4G module, an NB-IOT module, a WIFI module, a ZIGBEE module, or a bluetooth module. And if the network label of the WIFI module is the MAC address, the network label of the ZIGBEE module or the Bluetooth module is an address code.
The default device ID may be 0x 00000000.
In S20, the unique IMEI code of the device is registered at the server, including the newly-connected device and the existing network device with the replaced networking module.
Example 2
Referring to fig. 2, in S30, after the device end of the internet of things is turned on, the device end reads the device ID of the E2PROM, and after sending a device ID allocation application to the server when the determination condition is satisfied, the following steps are performed:
s31, judging whether the ID is factory default equipment ID;
s32, if yes, sending an application for distributing equipment ID to the server, and simultaneously sending an IMEI code corresponding to the networking module;
and S33, if not, the format is correct, the current network equipment has the equipment ID and does not send the application for distributing the equipment ID.
After the equipment end of the Internet of things is started, an embedded program operated by the equipment end reads the equipment ID in the E2PROM, and two branches are arranged after reading: if the number is 0X00000000, sending an ID allocation request and an IMEI code to the server; if not 0X00000000, the device is regarded as a current network device, and the ID allocation request is not sent to the server. Therefore, the situation that the same device has a plurality of IDs at the server side due to repeated distribution of the device IDs is avoided.
Example 3
Referring to fig. 3, S40, after receiving the device ID allocation application and the IMEI code corresponding to the device, the server compares and processes the IMEI code with the device database, and the processing includes the following steps:
s41, whether the IMEI code corresponding to the equipment exists in the database or not;
s42, if yes, the device changes E2PROM, and sends down the device ID in the server database;
and S43, if not, indicating that the network is a new network access device, and the server allocates a new device ID for issuing.
Example 4
Referring to fig. 4, S50, when the internet of things device uploads data in use, the data packet header includes a device ID and an IMEI code, the server reads the IMEI code and the device ID at the same time, and compares and processes the IMEI code and the device ID with the device database, and the processing includes the following steps:
s51, whether the IMEI code and the equipment ID are matched with certain equipment information in the database or not;
s52, if the IMEI code and the equipment ID are matched with certain equipment information at the same time, the equipment is the normal network equipment, and data is written into the database;
and S53, the IMEI code and the equipment ID can be matched with different equipment respectively, and if the equipment 1 can be matched with the IMEI code and the equipment 2 can be matched with the equipment ID, merging the two equipment in the database and then writing data.
Neither the IMEI code nor the device ID match any device information, which is a situation that does not exist in practice, and therefore will not be described.
The embodiment 3 is a case where the device is replaced with the E2PROM, and the device ID is not lost and remains unchanged; example 4 in the case of a device having a networking module replaced, the device 1 and the device 2 in the database are actually the same device, and the device ID can still be kept unchanged, instead of reassigning the ID. The integral management is clear, and the IMEI code and the equipment ID correspond to the equipment one by one.
It should be understood that the exemplary embodiments described herein are illustrative and not restrictive. Although one or more embodiments of the present invention have been described with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
