Background
The traditional equipment does not need to communicate with the outside, and usually, the equipment identifier is adhered to the surface of the equipment in the form of a label, so that the requirements of equipment management or equipment tracing and the like are met.
The traditional equipment does not need to be communicated with the outside, so that an equipment identifier does not need to be arranged in the equipment, and the equipment identifier is usually adhered to the surface of the equipment in a label mode so as to meet the requirements of equipment management or equipment tracing and the like, so that corresponding equipment identifier writing stations, tools and production rhythm control are not arranged in the production process flow.
With the continuous development of scientific technology, intelligent devices embedding communication modules into traditional devices are becoming more and more common. After the intelligent management is added to the device, a unique device identifier needs to be written into the device, so that the intelligent device can communicate with the outside.
At present, if equipment identification is written in the production process, the existing production line needs to be upgraded and modified, equipment identification writing equipment needs to be added, and equipment identification writing procedures need to be added, so that the productivity is reduced.
Disclosure of Invention
The invention provides a method and a device for acquiring an equipment identifier, which are used for solving the problems that in the prior art, when the equipment identifier is written, an upgrading production line needs to be improved, equipment identifier writing equipment needs to be purchased, and equipment identifier writing procedures need to be added, so that the productivity is reduced.
In a first aspect, a method for obtaining an apparatus identifier provided in an embodiment of the present invention includes: an NB-IoT (NarrowBand band-Internet Of Things) module judges whether the device identification Of the target device can be obtained from the target device to be controlled; if the equipment identification of the target equipment cannot be acquired from the target equipment needing to be controlled, the NB-IoT module sends the module identification of the NB-IoT module to a network side; the NB-IoT module receives the equipment identification which is returned by the network side and is bound with the module identification; the NB-IoT module takes the received equipment identification as the equipment identification of the target equipment.
In the method, the NB-IoT module determines whether the device identifier of the target device can be obtained from the target device to be controlled, and if the device identifier of the target device cannot be obtained from the target device to be controlled, the NB-IoT module sends the module identifier of the NB-IoT module to the network side, the network side returns the device identifier bound with the module identifier of the NB-IoT module, which is stored in the network side, to the NB-IoT module, and the NB-IoT module uses the received device identifier as the device identifier of the target device to be controlled by the NB-IoT module. The device identification of the target device is obtained from the network side through the NB-IoT module, so that the device identification does not need to be obtained in the production process, and a large amount of funds are saved while the productivity is improved.
In one possible implementation, the NB-IoT module sends the received device identifier and the module identifier of the NB-IoT module to the target device.
In the possible implementation manner, the target device receives the device identifier and the module identifier, and the corresponding relationship between the device identifier and the module identifier is implemented, so that the target device and the NB-IoT module are bound.

In the possible implementation manner, the NB-IoT module can obtain the device identifier from the target device, and if it is determined that the NB-IoT module bound to the target device is replaced, the module identifier of the NB-IoT module and the device identifier of the target device are sent to the network side, so that the network side updates the binding relationship between the module identifier and the device identifier. Because the network side stores the binding relationship between the module identifier and the device identifier before the NB-IoT module is replaced, the binding relationship between the module identifier and the device identifier stored in the network side needs to be updated after the NB-IoT module is changed.
In one possible implementation manner, if the NB-IoT module cannot acquire the device identifier bound to the module identifier from the NB-IoT module, it is determined that the NB-IoT module bound to the target device is replaced; or if the module identification bound by the equipment identification acquired by the NB-IoT module from the target equipment is different from the module identification of the NB-IoT module, determining that the NB-IoT module bound with the target equipment is replaced; or if the device identification acquired by the NB-IoT module from the target device is different from the device identification stored in the NB-IoT module, determining that the NB-IoT module bound with the target device is replaced.
The above possible implementation manners list three cases of determining that the NB-IoT module bound to the target device is replaced.
In a possible implementation manner, the NB-IoT module can obtain the device identifier of the target device from the target device to be controlled, and send the module identifier of the NB-IoT module to the target device after determining that the NB-IoT module bound to the target device is replaced.
In the possible implementation manner, the NB-IoT module can obtain the device identifier of the target device, and determine that the NB-IoT module bound to the target device is replaced, then send the module identifier of the NB-IoT module to the target device, and the module identifier of the NB-IoT module and the device identifier in the target device implement a corresponding relationship, so as to implement the binding between the NB-IoT module and the target device.

Different from the traditional equipment, the intelligent equipment is additionally provided with a communication module, and the communication between the communication module and the server is utilized, so that the remote control of the equipment is realized. For example, in order to implement intelligent management of air conditioners, a unique device ID needs to be written into each air conditioner as a device identifier, when a user uses a smart home application on a mobile phone, the device ID of the air conditioner needs to be used as a unique binding identifier to bind an application program and the air conditioner, and after the application program and the air conditioner are bound, the air conditioner can be managed.
Binding the application program and the device identifier requires acquiring the device identifier.
The embodiment of the invention acquires the equipment identifier through the NB-IoT module embedded in the equipment.
The NB-IoT is a narrowband Internet of things and has the characteristics of wide coverage, more connections, high speed, low cost, low power consumption, excellent architecture and the like.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, a method for obtaining a device identifier provided in an embodiment of the present invention specifically includes the following steps:
s100, judging whether the device identification of the target device can be acquired from the target device needing to be controlled by an NB-IoT module;
s101, if the equipment identification of the target equipment cannot be acquired from the target equipment needing to be controlled, the NB-IoT module sends the module identification of the NB-IoT module to a network side;
s102, the NB-IoT module receives the equipment identification which is returned by the network side and is bound with the module identification;
s103, the NB-IoT module takes the received equipment identification as the equipment identification of the target equipment.
The NB-IoT module judges whether the device identification of the target device can be acquired from the target device to be controlled, if the device identification of the target device cannot be acquired from the target device to be controlled, the module identification of the NB-IoT module is sent to the network side, the device identification which is stored by the network side and is bound with the module identification of the NB-IoT module is returned to the NB-IoT module by the network side, and the NB-IoT module takes the received device identification as the device identification of the target device to be controlled by the NB-IoT module. The device identification of the target device is obtained from the network side through the NB-IoT module, so that the device identification does not need to be obtained in the production process, and the production is improved while a large amount of funds are saved.
The equipment in the embodiment of the invention can be an intelligent air conditioner, an intelligent television, an intelligent refrigerator and the like, and all the equipment which can be controlled by the NB-IoT module is suitable for the embodiment of the invention.
The module ID of the NB-IoT module is taken as an example, and the equipment ID is taken as an example to describe the present invention.
In implementation, the module ID is already written into the NB-IoT module when the NB-IoT module is produced, but there is a possibility that the NB-IoT module does not have a device ID in the devices that need to be controlled, so the device ID is obtained.
Firstly, in the production process of the equipment, recording the corresponding relation between the equipment ID and the module ID distributed to the equipment, and then uploading the corresponding relation to a specified server, wherein if the corresponding relation between the equipment ID and the module ID exists, the equipment ID information of the equipment does not need to be scanned and recorded, and only the equipment ID label needs to be printed and then pasted on the equipment. As shown in fig. 2, the specific steps are as follows:
200, entering an equipment ID label pasting station after the equipment function check is finished;
step 201, scanning and recording module ID information of an NB-IoT module;
step 202, judging whether an equipment ID information label of the terminal equipment exists, if so, executing step 203, otherwise, executing step 205;
step 203, scanning and inputting the ID information of the label of the existing terminal equipment;
step 204, establishing a corresponding relation between the module ID and the equipment ID, and sending the corresponding relation to a specified server;
step 205, printing the device ID tag;
step 206, pasting an equipment ID label on the terminal equipment;
and step 207, packaging and warehousing the terminal equipment.
The method comprises the steps that the corresponding relation between a module ID and an equipment ID is established in the production process of equipment and uploaded to a designated server, the equipment is powered on and started up for the first time after leaving a factory, an NB-IoT module and the equipment establish communication, the NB-IoT module reads equipment ID information and binding information of the equipment, wherein the binding information of the equipment is the module ID information of the NB-IoT module which is bound with the equipment last time, the NB-IoT module reads module binding information in the NB-IoT module, and the module binding information is the equipment ID information of the equipment which is bound with the last time.
When the NB-IoT module reads information in the device and the NB-IoT module, there are three cases, which are the first binding of the device and the NB-IoT module, the replacement of the motherboard in the device, and the replacement of the NB-IoT module, respectively, and the following description is provided for the three cases.
Scene one, primary binding of equipment and NB-IoT module:
the equipment is powered on and started for the first time, the NB-IoT module firstly reads equipment ID information and binding information of the equipment in the equipment, then module binding information in the NB-IoT module is read, if the equipment does not have the equipment ID information and the binding information of the equipment, and the NB-IoT module does not have the module binding information, the equipment and the NB-IoT module are determined to be bound for the first time, and at the moment, the NB-IoT module sends the module ID of the NB-IoT module to the network side equipment.
In the production process, the corresponding relation between the equipment ID and the module ID is uploaded to a specified server, namely, the network side equipment, so that when the NB-IoT module sends the module ID of the NB-IoT module to the network side equipment, the network side equipment sends the equipment ID corresponding to the module ID of the NB-IoT module, which is stored in the network side equipment, to the NB-IoT module.
And the NB-IoT module receives the equipment identification which is returned by the network side and is bound with the module identification.
Since the device ID returned by the network-side device is the device ID stored in the network-side device and corresponding to the module ID of the NB-IoT module, the received device ID is the target device ID, that is, the device ID of the device that the NB-IoT module needs to control.
For example, in the process of producing the device, the device ID assigned to the device is A, B, C, the module ID of the NB-IoT module is D, E, F, and the correspondence between the device ID and the module ID assigned to the device is recorded as: a corresponds to D, B corresponds to E, C corresponds to F, if the NB-IoT module with the module ID of D does not read the equipment ID from the equipment, the NB-IoT module sends the module D to the network side, the equipment of the network side inquires that the equipment ID corresponding to D is A, and the A is returned to the NB-IoT module.
And after the NB-IoT module receives the equipment ID, the equipment ID and the module ID are sent to the target equipment.
Optionally, the NB-IoT module sends the received device identifier and the module identifier of the NB-IoT module to the target device.
And after receiving the module ID and the equipment ID sent by the NB-IoT module, the target equipment writes the equipment ID into the equipment and stores the equipment ID and the module ID in the equipment.
Scene two, main board replacement in the equipment:
the equipment is powered on and started for the first time, the NB-IoT module firstly reads equipment ID information and binding information of the equipment, then module binding information in the NB-IoT module is read, if the equipment does not have the equipment ID information and the binding information of the equipment, and the NB-IoT module has the module binding information, the mainboard in the equipment is determined to be replaced, at the moment, the NB-IoT module communicates with the network side equipment, and the module ID of the NB-IoT module is sent to the network side equipment.
In the production process, the corresponding relation between the equipment ID and the module ID is uploaded to a specified server, namely, the network side equipment, so that when the NB-IoT module sends the module ID of the NB-IoT module to the network side equipment, the network side equipment sends the equipment ID corresponding to the module ID of the NB-IoT module, which is stored in the network side equipment, to the NB-IoT module.
And the NB-IoT module receives the equipment identification which is returned by the network side and is bound with the module identification.
Since the device ID returned by the network-side device is the device ID stored in the network-side device and corresponding to the module ID of the NB-IoT module, the received device ID is the target device ID, that is, the device ID of the device that the NB-IoT module needs to control.
And after the NB-IoT module receives the equipment ID, the equipment ID and the module ID are sent to the target equipment.
Optionally, the NB-IoT module sends the received device identifier and the module identifier of the NB-IoT module to the target device.
And after receiving the module ID and the equipment ID sent by the NB-IoT module, the target equipment writes the equipment ID into the equipment and stores the equipment ID and the module ID in the equipment.
Scene three, the NB-IoT module is replaced:
if the NB-IoT module reads the equipment ID information, the equipment ID information can be read, but the module ID information stored in the equipment is different from the module ID information of the NB-IoT module, or the module ID information stored in the equipment read by the NB-IoT module from the equipment is different from the module ID information of the NB-IoT module, or the equipment ID information is not stored in the NB-IoT module, the NB-IoT module is judged to be replaced at the moment.
Optionally, if the NB-IoT module cannot obtain the device identifier bound to the module identifier from the NB-IoT module, determining that the NB-IoT module bound to the target device is replaced; or
If the module identification bound by the equipment identification acquired by the NB-IoT module from the target equipment is different from the module identification of the NB-IoT module, determining that the NB-IoT module bound with the target equipment is replaced; or
And if the device identification acquired by the NB-IoT module from the target device is different from the device identification stored in the NB-IoT module, determining that the NB-IoT module bound with the target device is replaced.
When the NB-IoT module and the device are bound, the network-side device returns device ID information corresponding to the module ID information of the NB-IoT module to the NB-IoT module, the NB-IoT module stores the device ID information and sends the device ID information and the module ID information of the NB-IoT module to the device, and the device writes the received device ID information into the device and stores the device ID information and the module ID information of the NB-IoT module.
For example, if the device with device ID information a is bound with the NB-IoT module with module ID information B, the ID information written in the device is a, the device ID information stored in the device is a, the stored module ID information is B, and the device ID information stored in the NB-IoT module is a.
In implementation, the device is powered on for the first time, the NB-IoT module first reads the device ID information and the module ID information stored in the device from the device, and then reads the device ID information stored in the NB-IoT module.
The module ID information stored in the device is the module ID information of the NB-IoT module that was last bound to the device, and if the module ID information stored in the device is null information, it indicates that the device has not been bound to the NB-IoT module.
The device ID information stored in the NB-IoT module is the device ID information of the device that was last bound to the NB-IoT module, and if the device ID information stored in the NB-IoT module is null information, it indicates that the NB-IoT module has not been bound to the device.
If the device ID information in the device read by the NB-IoT module is not consistent with the device ID information stored in the NB-IoT module, the NB-IoT module is replaced.
For example, if the device ID information in the device read by the NB-IoT module is a and the device ID information stored in the NB-IoT module is B, it indicates that the device bound to the NB-IoT module last time is a device whose device ID information is B, so it is determined that the NB-IoT module in the device whose device ID information is a has been replaced.
If the module ID information stored in the equipment read by the NB-IoT module is not consistent with the module ID information of the NB-IoT module, the NB-IoT module is replaced.
For example, if the module ID information stored in the device read by the NB-IoT module is C and the module ID information of the NB-IoT module is D, it indicates that the NB-IoT module last bound to the device is the NB-IoT module whose module ID information is C, so that it is determined that the NB-IoT module in the device has been replaced and the module ID information of the replaced NB-IoT module is D.
If the NB-IoT module read has no equipment ID information, the NB-IoT module can be also indicated to be replaced.
The NB-IoT module can read the equipment ID information of the equipment and the module ID information stored in the equipment, so that the equipment is bound, and if the NB-IoT module in the equipment does not have the equipment ID information, the NB-IoT module is not bound, so that the NB-IoT module in the equipment is determined to be replaced.
The NB-IoT module can read the device ID from the device and can determine that the NB-IoT module in the device is replaced, and the binding relationship information of the device ID and the module ID stored on the network side needs to be updated.
Optionally, the NB-IoT module may obtain the device identifier of the target device from the target device to be controlled, and send the module identifier of the NB-IoT module and the device identifier of the target device to a network side after determining that the NB-IoT module bound to the target device is replaced, so that the network side updates the binding relationship between the module identifier and the device identifier.
For example, in the production process, if the device with the device ID information of a and the NB-IoT module with the module ID information of B establish a binding relationship, the binding relationship stored in the remote server is that a corresponds to B, and if the NB-IoT module in the device is replaced and the replaced module ID information is C, the corresponding relationship between a and B in the remote server should be updated to a and C.
The specific updating mode is that the NB-IoT module sends the module ID information C and the equipment ID information A to the network side equipment, the network side equipment inquires the module ID information B corresponding to the equipment ID information A and stored in the network side equipment according to the equipment ID information A, the module ID information B is replaced by the module ID information C, and the corresponding relation between the module ID information of the NB-IoT module and the equipment ID information in the server is completed.
And after the network side updates the binding relationship between the module identification and the equipment identification, the NB-IoT module sends the module identification of the NB-IoT module to the target equipment.
Optionally, the NB-IoT module may obtain the device identifier of the target device from the target device that needs to be controlled, and send the module identifier of the NB-IoT module to the target device after determining that the NB-IoT module bound to the target device is replaced.
And after the target equipment receives the module identification sent by the NB-IoT module, storing the received module identification into the equipment, and deleting the module identification of the NB-IoT module which is stored in the equipment and is bound with the equipment last time.
