Problems solved by technology

[0003] The above-mentioned IoT device ID allocation method has the following problems: (1) If the networking module of the existing network device fails, after replacing a new networking module, the IMEI code has changed, and it needs to be re-registered on the server side, and the server side will Re-assign a device ID for this device
In this way, in the server-side database, the same device corresponds to two device IDs, resulting in confusion when maintaining the data uploaded by the device.
(2) If the E2PROM of the Internet of Things device fails and is replaced, the device ID information will be lost, which will cause the server to be unable to determine which device the data uploaded when the device is working belongs to.

Embodiment 1

[0036] see figure 1 , the invention discloses a method for intelligently assigning IDs of IoT devices. The IoT devices include a networking module and E2PROM. The networking module is assigned a unique IMEI code when it leaves the factory. The E2PROM is used to store the device ID. The smart allocation method includes the following steps:

[0037] S10, on the IoT device side, the default device ID is uniformly written in the E2PROM of each device when leaving the factory;

[0038] S20, the unique IMEI code of each normal working device is registered on the server side to obtain the network permission;

[0039] S30, after the Internet of Things device is turned on, the device reads the device ID of the E2PROM, and sends a device ID allocation application to the server when the judgment condition is met;

[0040] S40, after the server receives the device ID allocation application and the IMEI code corresponding to the device, compares and processes the IMEI code with the devic...

Embodiment 2

[0046] see figure 2 , S30, after the Internet of Things device is turned on, the device reads the device ID of the E2PROM, and when the judgment condition is satisfied, after sending the device ID allocation application to the server, the following steps are performed:

[0047] S31, judging whether it is a factory default device ID;

[0048] S32, if yes, send an application for assigning a device ID to the server, and at the same time send the IMEI code of the corresponding networking module;

[0049] S33, if no, and the format is correct, then it is an existing network device with an existing device ID, and no application for assigning a device ID is sent.

[0050] After the Internet of Things device is turned on, the embedded program running on the device reads the device ID in the E2PROM, and there are two branches after reading: if it is 0X00000000, it will send the ID allocation request and IMEI code to the server; if it is not 0X00000000, it will It is regarded as a l...

Embodiment 3

[0052] see image 3 , S40. After the server receives the device ID allocation application and the IMEI code corresponding to the device, it compares and processes the IMEI code with the device database. The processing includes the following steps:

[0053] S41, whether the IMEI code corresponding to the device already exists in the database;

[0054] S42, if yes, it means that the device has replaced the E2PROM, and the existing device ID in the database of the server is issued;

[0055] S43, if no, it means that it is a new network-connected device, and the server assigns a new device ID and delivers it.

Abstract

The invention discloses an Internet of Things device ID intelligent distribution method, which comprises the following steps: S10, uniformly writing default device IDs into an E2PROM of each device atan Internet of Things device end when the Internet of Things device leaves a factory; S20, the unique IMEI code of each normally working device is registered at the server side, and networking permission is obtained; 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 allocation application to theserver when a judgment condition is met; s40, after the server receives the equipment ID distribution application and the IMEI code corresponding to the equipment, comparing and processing the IMEI code with an equipment database; and S50, when the Internet of Things equipment uploads data in use, an equipment ID and an IMEI code are contained in a data packet header, and the server reads the IMEIcode and the equipment ID at the same time and compares and processes the IMEI code and the equipment ID with an equipment database. According to the invention, after the networking module of the Internet of Things device is replaced, the ID of the device can still be kept unchanged; after the E2PROM is replaced, the device ID is not lost and remains unchanged.

Description

technical field [0001] The invention belongs to the field of Internet of Things communication, and in particular relates to a method for intelligently assigning IDs of Internet of Things devices. Background technique [0002] In the prior art, the method for assigning the ID of the Internet of Things device is as follows: (1) The networking module of the Internet of Things device is assigned a unique IMEI code, and each networked device uses the IMEI code to register on the server to obtain access to the server. A unique device ID will be assigned to a device with a newly registered IMEI code, and will be issued after the device is connected to the Internet; (2) After the new Internet of Things device is turned on, it will connect to the server, and the server will issue the device ID after authentication. (3) The IoT device receives the ID number and stores it in a storage device such as E2PROM. [0003] The above-mentioned IoT device ID allocation method has the following...
