[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] Reference Figure 1 In one embodiment of the present application, a method for identifying a location change of an electronic device is provided, comprising:

[0040] S1. Acquire a first wireless device list collected at the current moment, where the first wireless device list includes names of wireless devices that can be searched by the electronic device at the current moment;

[0041] S2. Calculate the difference between the first wireless device list and the second wireless device list collected at a historical moment to obtain a difference list;

[0042] S3, calculating the difference number of wireless devices in the difference list;

[0043] S4, determining whether the difference quantity is greater than a preset threshold quantity;

[0044] S5. If yes, determine that the location of the electronic device has changed.

[0045] In this embodiment, the electronic device refers to an electronic device such as an all-in-one machine, a smart display screen, etc., which has components such as a controller, a memory, and a display screen, and the execution subject of the above method is the controller of the electronic device. When the electronic device is in use, it is usually fixed in a certain place, so it usually does not have a positioning module, but it has a Bluetooth module or a WiFi module for short-distance wireless transmission devices, which can interact with other wireless devices. The electronic device can turn on the Bluetooth module or WiFi module at any time to search for wireless devices around it; or the electronic device receives the corresponding instruction or generates the corresponding instruction in combination with its own parameters to perform the search, obtains the wireless device that can be scanned, and obtains the name of each wireless device to form a first wireless device list. In a specific embodiment, the names of each wireless device in the first wireless device list are sorted according to the signal strength that can be received. Then call the second wireless device list collected at the historical moment. When multiple second wireless device lists are stored in the memory, select the second wireless device list collected at the most recent historical moment, and then calculate the difference between the first wireless device list and the second wireless device list to obtain a difference list. Difference calculation is to compare the two wireless device lists, select the names of all wireless devices that do not appear in both the first wireless device list and the second wireless device list, and obtain a difference list. The difference list is used to reflect the difference between the first wireless device list and the second wireless device list, and can also be calculated by other calculation methods. If the difference between the two is large, that is, the number of differences is large, it is determined that the position of the electronic device has changed.

[0046] In one embodiment, the step of calculating the difference between the first wireless device list and the second wireless device list collected at a historical moment to obtain a difference list includes:

[0047] S21. Calling a pre-stored fixed wireless device list, wherein the fixed wireless device list stores names of fixed wireless devices in a specified environment;

[0048] S22, filtering out the first name of the fixed wireless device in the first wireless device list and the second name in the second wireless device list;

[0049] S23. Calculate the difference between the first name and the second name to obtain a difference list.

[0050] In this embodiment, the electronic device is used in a designated environment, such as in a research and development building. The designated environment has multiple wireless devices such as routers, or other fixed wireless devices with Bluetooth modules, which are all fixedly installed in the research and development building, that is, fixed wireless devices. The administrator will summarize the names of all fixed wireless devices in the designated environment to obtain a fixed wireless device list, and store the fixed wireless device list in the electronic device, or in each fixed wireless device, so that the electronic device can call it. In a specific embodiment, the fixed wireless device list is stored in each fixed wireless device. In order to prevent the fixed wireless device list from being known by others, when the electronic device calls the fixed wireless device list, the current time and the device number of the electronic device are input into a preset encryption algorithm to generate a random key, and then the random key is sent to any fixed wireless device. Then the fixed wireless device uses a pre-stored decryption algorithm to parse the random key. If the parsing is successful, it is determined to be the above-mentioned electronic device, and the fixed wireless device list is sent to the electronic device. Among them, the method for determining that the sending object is a fixed wireless device is: the electronic device broadcasts the random key so that the surrounding fixed wireless devices can receive the random key; another method can also be used: the electronic device continuously collects wireless devices twice in a short period of time to obtain two wireless device lists, and defines the wireless devices that appear in both wireless device lists as pre-fixed devices, and then sends the above random key to the pre-fixed device. If the pre-fixed device is a non-fixed device, no data will be returned. If the pre-fixed device is a fixed device, it will be parsed and then return the above fixed wireless device list. In this way, even if other non-fixed wireless devices receive the random key, they cannot obtain the specific meaning of the random key because they do not have the above decryption algorithm; other non-fixed wireless devices cannot generate the above random key to obtain the fixed wireless device list because they do not have the encryption algorithm. After the electronic device obtains the fixed wireless device list, the fixed wireless devices in the first wireless device list are screened out to obtain the first name, which is the collective name of the names of multiple fixed devices in the first wireless device list; similarly, the second name is the collective name of the names of multiple fixed devices in the second wireless device list. Then the number of differences between the first name and the second name is calculated to obtain a difference list. Take a specific implementation for illustration: the names of the wireless devices in the first wireless device list are: A1, A2, A4, B1, B3; the names of the wireless devices in the second wireless device list are: A2, A3, B1, B2; the list of fixed wireless devices obtained by the electronic device is: A1, A3, A5, A7, B1, B2, B3, B4.The first list of electronic devices screened out is: A1, B1, B3; the second list is: A3, B1; the corresponding difference list of fixed wireless devices that do not appear in both is: A1, B3, A3; the number of differences is 3, and then 3 is compared with the preset threshold number. If the threshold number is 2, it is determined that the location of the electronic device has changed.

[0051] In one embodiment, after the step of filtering out the first name of the fixed wireless device in the first wireless device list, the method further comprises:

[0052] S24, acquiring signal strengths between the fixed wireless devices corresponding to the first names and location information of the fixed wireless devices corresponding to the first names;

[0053] S25. Calculate the location of the electronic device according to the signal strength and the location information.

[0054] In this embodiment, the above-mentioned fixed wireless device list also includes the location information of each fixed device, and each location information refers to the location information of the fixed device in a specified environment, such as the wireless router in the A02 conference room on the 5th floor, the wireless router in the 406 legal office on the 4th floor, and the wireless router above the table tennis table in the leisure and entertainment room on the 28th floor. The electronic device can calculate the distance to each fixed wireless device based on the signal strength between the electronic device and the location information of each fixed wireless device, and based on the principle that the closer the distance to the fixed wireless device, the stronger the signal strength, so as to finally calculate the location of the electronic device, so that the electronic device can be positioned in real time.

[0055] In one embodiment, before the step of obtaining the first wireless device list collected at the current moment, the step includes:

[0056] S101: after obtaining that the electronic device is powered on, generate a collection command, wherein the collection command is used to instruct the electronic device to obtain a first wireless device list collected at the current moment.

[0057] In this embodiment, the electronic device itself does not have a battery. When the power is turned on or an external battery is connected, it is determined that the electronic device is powered on, and a collection command is generated to enable the electronic device to turn on the wireless module and search for nearby wireless devices through the Bluetooth module or the WiFi module, thereby generating a first wireless device list. Alternatively, the electronic device itself has a battery, and when the electronic device is turned on, a collection command is generated.

[0058] In one embodiment, the method for acquiring the second wireless device list is:

[0059] S102: After obtaining that the electronic device is powered off, start the delay circuit, turn on the wireless module to search, and obtain a second wireless device list.

[0060] In this embodiment, the electronic device itself does not have a battery, but it has a delay circuit. When the electronic device is powered off, the delay circuit is turned on to maintain the operation of the wireless module and a coprocessor, and provide power for the two. The wireless module searches for nearby wireless networks and then obtains a second wireless device list. After the above-mentioned electronic device is powered on, a collection command is generated, that is, the electronic device collects a wireless device list after each power-on and power-off. After power-on, the first wireless device list is immediately collected, and combined with the second wireless device list collected after the last power-off, it is calculated whether the location has changed. After each power-off, the second wireless device list is collected again to facilitate the judgment of whether the location has changed after the next power-on.

[0061] In one embodiment, after the step of determining whether the location of the electronic device has changed, the following steps are included:

[0062] S6. Sending information on reporting location change to any wireless device in the first wireless device list, so that the wireless device uploads the reporting information to a designated server.

[0063] In this embodiment, when the location of the electronic device changes, it needs to be sent to the administrator in a timely manner so that the administrator can effectively manage it. Specifically, the location change information is sent to any wireless device in the first wireless device list. In a specific embodiment, the information reporting the location change is sent to any fixed wireless device. In another specific embodiment, the above-calculated location of the electronic device is sent to any fixed wireless device, and the current time and the number of the electronic device are sent at the same time, so that after uploading to the server, the server can effectively track and manage the electronic device.

[0064] In one embodiment, after the step of obtaining the first wireless device list collected at the current moment, the following steps are included:

[0065] S111, if there is no designated wireless device in the first wireless device list, start the signal booster and search again to obtain a boost list;

[0066] S112: If the enhanced list includes the name of the designated wireless device, send designated information to the designated wireless device to remind the user that the electronic device is about to move away from the user.

[0067] In this embodiment, when the electronic device fails to search for the designated wireless device, in a specific embodiment, the designated wireless device is the above-mentioned fixed wireless device. If there is no above-mentioned fixed wireless device in the first wireless device list, the signal booster and the wireless module are started to search again to search for wireless devices farther away, obtain a strengthened list, and then determine whether there is the above-mentioned designated wireless device in the strengthened list. If there is, send designated information to the above-mentioned designated wireless device to remind the user of the electronic device that the electronic device is about to leave the environment of the designated wireless device, that is, the electronic device may be stolen. Sending the message immediately can let the user know its special situation, so as to effectively manage the electronic device.

[0068] In summary, the method for identifying the location change of an electronic device of the present application determines whether the electronic device has been moved based on the wireless device list collected by the wireless module of the electronic device, and the location of the electronic device can be effectively managed without installing an additional positioning device.
