The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all the structures related to the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor a separate or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

Every mobile phone, tablet computer and other electronic devices are written with the International Mobile Equipment Identification Code, also known as the IMEI number. As the ID card of the electronic device, each electronic device has a globally unique IMEI number. It is understandable that in the process of using electronic devices, the international identification code of mobile devices needs to be used to verify mobile phones in many places. Electronic devices such as mobile phones and tablet computers have penetrated into people's daily life, and the functions of electronic devices are becoming more and more powerful. Generally, many third-party applications are installed on the electronic device, and more functions are realized through the third-party applications. Therefore, the electronic device needs to cooperate with the third-party applications when realizing certain functions. In order to confirm safety, third-party applications need to ensure that the electronic device is a regular factory machine. For example, the realization of the WeChat fingerprint payment function needs to verify the electronic device. Only when the international identification code of the mobile device written in the electronic device and the mobile device registered on the WeChat platform If the international identification code is the same, the WeChat fingerprint payment function can be used normally. Optionally, the above is just an example, and the third-party application may be QQ, Alipay, Vipshop, Xiaohongshu, etc., which is not specifically limited. In addition to the fingerprint payment function of a third-party application, the preset function can also be other functions related to payment or security.

Before the official mass production of electronic devices, there will be a trial production business. In many trial productions, the electronic devices are pre-researched in advance, so the certification application has not yet been submitted to the national government agency. In this case, the mobile phone cannot apply for official certification. Type approval number (also called TAC number), where the TAC number is the first 8 digits of the IMEI number. In order to carry out the trial production normally, the manufacturer of the electronic device will create a virtual TAC number that is not published by the state for the trial production business. . Before leaving the factory, the staff will mark and classify the electronic devices whose IMEI numbers have been rewritten and those whose IMEI numbers have not yet been rewritten. However, the above solutions often lead to some electronic devices leaving the warehouse without writing the IMEI number corresponding to the TAC number published by the state, resulting in some electronic devices leaving the warehouse. Electronic devices have quality problems. In this application, the MES system (manufacturing enterprise production process execution system, which is a set of production information management system oriented to the workshop execution layer of manufacturing enterprise) adds the IMEI number detection procedure before the electronic device is shipped out of the warehouse, so as to prevent the TAC number not published according to the state. Electronic devices with rewritten IMEI numbers are shipped out of the warehouse, resulting in quality problems.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of an embodiment of a method for checking the international identification code of a mobile device of an electronic device according to the present application. As shown in Figure 1, the method includes steps 101 to 103, wherein:

Step 101: Obtain the international identification code of the mobile device of the electronic device.

Since the mobile device international identification code of each electronic device is unique, it can be used as the verification code of the electronic device. Specifically, the international mobile equipment identification code is generally pasted on the back of the body and the outer packaging of the electronic device, and also exists in the mobile phone memory. It can be displayed on the screen of the mobile phone by entering a preset command, such as "* #06#” to query. In different embodiments of the present application, the international identification code of the mobile device may be obtained in different ways. The following description will be given by means of various embodiments. The international identification code of the mobile device of the electronic device is bound and stored in the preset database with other codes presented on the box or outer packaging. When the MES system obtains the international identification code of the mobile device of the electronic device, it can be obtained by accessing the preset database. The following is explained through different embodiments.

Optionally, in an embodiment, the MES system directly identifies or scans the back of the body or the outer package of the electronic device, and then obtains the international identification code of the mobile device of the electronic device for inspection. In another embodiment, the step of obtaining the international identification code of the mobile device of the electronic device includes: scanning a relevant pattern formed on the screen of the electronic device to obtain the international identification code of the mobile device of the electronic device. Specifically, the staff enters a preset command in the electronic device, so that the international identification code of the mobile device of the electronic device or a related pattern including the international identification code of the mobile device is displayed on the screen of the electronic device, and the MES system directly recognizes or scans the screen of the electronic device Characters or related patterns on the electronic device, such as a two-dimensional code or a barcode, can obtain the international identification code of the mobile device of the electronic device.

Specifically, the electronic devices are generally not shipped out one by one when they are out of the warehouse. If the international identification codes of the mobile devices of the electronic devices are obtained one by one for inspection, the speed is very limited. In general, electronic devices are shipped in boxes, and each box contains multiple electronic devices. In this embodiment, the box number of each box is different, as long as the international identification code of the mobile device of the electronic device is compared with the box number Binding, the MES system can obtain the international identification code of the mobile device corresponding to the electronic device in the box by obtaining the box number.

In this embodiment, the step of obtaining the international identification code of the mobile device of the electronic device includes: obtaining the box number on the packaging box of the electronic device to obtain the international identification code of the mobile device of the electronic device. Specifically, the international identification code of the mobile device of the electronic device is bound to the box number, and the box number and the international identification code of the mobile device of the electronic device are stored in a preset database, and then the box number on the packaging box of the electronic device is obtained to obtain The step of the mobile device international identification code of the electronic device includes: acquiring the box number on the packaging box of the electronic device, and using the box number to access a preset database to obtain the mobile device international identification code corresponding to the box number. Optionally, in an embodiment, the preset database is an internal database of the MES system, and the MES system can access the internal database as long as the box number is obtained to obtain the mobile device international identification codes of the plurality of electronic devices corresponding to the box number. In another embodiment, there may be only one electronic device in a box, which is not specifically limited. In other embodiments, the preset database is other equipment or platform other than MES, then the MES system is connected to the equipment or platform, and the mobile device international identification code of one or more electronic devices corresponding to the box number is searched and obtained according to the box number. .

Optionally, in an embodiment, the MES directly recognizes the box number displayed on the box through characters, or obtains the box number on the box by scanning a related pattern, such as a two-dimensional code or a barcode, displayed on the box.

Step 102: Detect whether the international identification code of the mobile device is a rewritten code.

It is understandable that the international identification code of the mobile device written in the trial production stage of the electronic device is written by the manufacturer itself. After applying for the official TAC number of the electronic device published by the state, rewrite the electronic device according to the TAC number published by the state. There must be significant differences in the International Identification Numbers of mobile devices. Therefore, it can be detected whether the international identification code of the mobile device of the electronic device is a rewritten code when the library is checked out according to the difference between the international identification code of the mobile device before and after the rewriting.

Optionally, in an embodiment, the step of detecting whether the international identification code of the mobile device is a rewritten code includes: detecting whether the encoding of the preset position of the international identification code of the mobile device is a preset encoding. It can be understood that, taking a mobile phone as an example, the International Mobile Equipment Identity (IMEI) of the electronic device, that is, the commonly known mobile phone serial number and the "serial number" of the mobile phone, is used to identify each mobile phone network in the mobile phone network. The mobile communication device of an independent mobile phone is equivalent to the ID card of the mobile phone. The serial number has 15 to 17 digits in total. The first 8 digits (TAC number) are the model approval number (6 digits in the early days), which is the code to distinguish the brand and model of the mobile phone. The next 2 digits (FAC number) is the last assembly number (existing only in earlier models), which represents the final assembly code. The last 6 digits (SNR number) are serial numbers, representing the production sequence number. The last 1 bit (SP number) is generally 0, which is the check code. Therefore, it can be recognized whether the international mobile equipment identification code of the electronic device is rewritten when the library is stored according to these characteristics of the regular international identification code of the mobile equipment.

It can be understood that, in order to make the MES system easier to detect, in an embodiment, the manufacturer of the electronic device does not write according to the above-mentioned existing characteristics of the international identification code of the mobile device, which reduces the difficulty of the MES system detection. In one embodiment, the step of detecting whether the international identification code of the mobile device is a rewritten code includes: detecting whether the encoding of the preset position of the international identification code of the mobile device is a preset encoding. Optionally, in an embodiment, the code of the preset position of the international identification code of the mobile device is the first two codes of the international identification code of the mobile device, for example, the first two codes of the international identification code of the mobile device are the international area code, such as China International Code. The area code is 86, the international area code of the United Kingdom is 35, and the international area code of the United States is 01. In other embodiments, the code of the preset position of the international identification code of the mobile device may also be the code of other positions, as long as the code is relatively fixed, or one of several codes, and the corresponding code written by the manufacturer of the electronic device. The encoding of the location does not have these encodings that may exist in the regular international identification code of the mobile device. In step 102, it can be detected whether the international identification code of the mobile device corresponding to the electronic device at the time of delivery has been rewritten according to the difference.

In another embodiment, the encoding of the preset position of the international identification code of the mobile equipment is a whole string of encodings, that is, the encoding of all positions of the international identification code of the mobile equipment in the entire string. In this embodiment, firstly, the international identification codes of mobile devices of all or part of the electronic devices in the batch (for example, are distinguished by the quantity shipped out of the warehouse each day) are stored in the preset data. The step of detecting whether the code of the preset position of the international identification code of the mobile device is a preset code includes: accessing a preset database to detect whether the international identification code of the mobile device is consistent with that stored in the preset database. That is, if the mobile device international identification code of each electronic device can be found exactly the same in the preset database, if it can be found, the mobile device international identification code of the electronic device is normal, and if it cannot be found, it is abnormal. Specifically, the preset database may be a database within the MES system, or may be other databases that are independent of the MES system but connected to the MES system, which are not specifically limited.

Step 103: Output the detection result.

Finally, the detection result is output. If the detection result is that the international identification code of the mobile device of the electronic device has not been rewritten, the electronic device cannot be released from the warehouse and needs to be rewritten. The above detection scheme uses the machine to automatically detect each electronic device before the electronic device is released from the warehouse, which is efficient and can well prevent the electronic device without re-writing the international identification code of the mobile device from being released from the warehouse, resulting in product quality problems.

Further, in one embodiment, if the detection result is abnormal, the step of outputting the detection result includes: prompting the reason for the abnormal detection result. For example, there is no rewriting, or only partial writing or no writing, and the international identification code of the mobile device is empty, which is not limited. It can be understood that if the detection result is abnormal, in this embodiment, the reason for the abnormal detection result is also prompted when the detection result is output, so that the staff can understand the root cause of the abnormality of the international identification code of the mobile device, and then can use the most accurate method. Write the International Mobile Device Identification Code for the electronic device.

Referring to FIG. 2 , it is a schematic flowchart of another embodiment of a method for checking the international identification code of a mobile device of an electronic device of the present application. The method is completed on the electronic terminal side, and the method includes step 201 . specific:

Step 201: In response to a preset command, output a pattern related to the international identification code of the mobile device of the electronic device on the screen, wherein the international identification code of the mobile device is a verification code for whether the electronic device can be shipped from the factory.

Specifically, the staff inputs a preset command in the electronic device, so that the international identification code of the mobile device of the electronic device or a related pattern including the international identification code of the mobile device is displayed on the screen of the electronic device. Make the MES system directly identify or scan the characters or related patterns on the screen of the electronic device. Optionally, the relevant pattern includes a barcode or a two-dimensional code, and the MES system can scan the relevant pattern on the screen of the electronic device to obtain the international identification code of the mobile device of the electronic device.

402: After receiving the preset command or the preset time period, the related pattern displayed on the screen of the electronic device disappears.

It can be understood that it only takes a short period of time for the electronic device to display the relevant pattern of the international identification code of the mobile device on the display screen for the machine or staff to recognize and obtain the information of the electronic device. In this embodiment, after the preset time period, The relevant pattern displayed on the screen of the electronic device disappears automatically. In other embodiments, the related pattern may disappear after the electronic device receives the preset command. In different embodiments, the preset command may be that the staff presses the back button or the Home button, or uses voice, or enters some preset commands. The command disappears, which is not specifically limited.
