Description

Technical Field

[0002] In the prior art, IoT devices are usually connected to edge gateways, which are then connected to the cloud, and the edge gateways are used to manage IoT devices. For example, the edge gateway directly manages the device data (such as system data) stored in the IoT device, or the IoT device uploads the device data (such as business data) to the edge gateway, which is then managed by the edge gateway. The edge gateway sends the device data (including system data and business data) to the cloud in real time so that the cloud can complete the data update; after receiving the background data from the cloud, the edge gateway controls the IoT device to complete the data update.

[0003] However, the above-mentioned edge gateway management scheme for IoT devices has at least the following problems: 1. The upper system indirectly obtains the device data of the IoT device through the edge gateway, which is cumbersome and inefficient, easily affected by network stability, and has a slow response speed; if the network is unstable, it is impossible to accurately determine the location of the fault; 2. The edge gateway processes data from multiple different IoT devices, which may easily exceed the bandwidth limit of the edge gateway due to excessive data traffic, causing network congestion and delays; 3. Due to the use of a large number of edge gateways, when the edge gateways are actually deployed, it is easy to cause problems such as inconvenient wiring and scattered distribution of the edge gateways, which makes it inconvenient to uniformly manage IoT devices.

[0061] Unless otherwise defined, the technical terms and scientific terms used in this specification have the same meanings as those generally understood by those of ordinary skill in the art of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0062] See also Figure 1 , Figure 1 Schematic diagram of application scenarios of the data management method provided for some embodiments of the present invention. In this application scenario, an electronic device 10, a cloud 20 and a docking system 30 are included. The cloud 20 is respectively connected to the electronic device 10 and the docking system 30 through a communication network, and data can be exchanged between the cloud 20 and the electronic device 10, and between the cloud 20 and the docking system 30. For example, the electronic device 10 sends the device data associated with the electronic device 10 to the cloud 20, or the cloud 20 sends the background data associated with the electronic device 10 to the electronic device 10, or the cloud 20 sends the device data associated with the electronic device 10 to the docking system 30, etc. It should be understood that the above-mentioned communication network includes but is not limited to the Internet, a local area network, an intranet, a mobile communication network, a wireless network and a combination thereof.

[0063] Specifically, after receiving the device data associated with the electronic device 10, the cloud 20 forms a device data shadow based on the device data and stores it in the cloud 20; thus, the docking system 30 does not need to obtain the device data associated with the electronic device 10 through the gateway device, but only needs to read the device data shadow stored in the cloud 20.

[0064] In some embodiments, the electronic device 10 forms a device data body according to the device data, and generates a device body summary according to the device data body. After receiving the device data associated with the electronic device 10, the cloud 20 forms a device data shadow with the device data, and then generates a device shadow summary according to the device data shadow. The cloud 20 also generates background data associated with the electronic device 10 according to the device data, sends the background data to the electronic device 10, and forms the background data into a background data body, and then generates a background body summary according to the background data body. After receiving the background data associated with the electronic device 10, the electronic device 10 is initialized according to the background data, and then forms the background data into a background data shadow, and stores it in the electronic device 10, and generates a background shadow summary according to the background data shadow.

[0065] Among them, the electronic device 10 sends the device body summary and the background shadow summary to the cloud 20 in a polling manner. The cloud 20 receives the device body summary and the background shadow summary, and compares the device body summary with the device shadow summary, and compares the background shadow summary with the background body summary, to determine whether the device data and / or background data have changed. After determining that the device data and / or background data have changed by comparing the summaries, the device data and / or background data are updated. This avoids unnecessary traffic consumption caused by the electronic device 10 sending device data and / or background data in a polling manner when the device data and / or background data have not changed, which can save traffic and reduce traffic waste.

[0066] It can be understood that when the device data associated with the electronic device 10 changes, the electronic device 10 updates the device data, updates the device body summary according to the updated device data, and sends the updated device data to the cloud 20. When the background data associated with the electronic device 10 changes, the cloud 20 updates the background data, updates the background body summary according to the updated background data, and sends the updated background data to the electronic device 10. The cloud 20 receives the updated device data and updates the device shadow summary according to the updated device data. The electronic device 10 receives the updated background data and updates the background shadow summary according to the updated background data.

[0067] Those skilled in the art will understand that Figure 1The application scenario shown in the embodiment only schematically illustrates a situation in which data is exchanged between the electronic device 10, the cloud 20 and the docking system 30, and does not impose any limitation on any situation in which data is exchanged between the electronic device 10, the cloud 20 and the docking system 30 in other application scenarios. Figure 1 The illustrated embodiment does not impose any limitation on the structure, type, composition, data interaction method, etc. of the electronic device 10 , the cloud 20 , and the docking system 30 .

[0079] The following describes in detail a data management method applied to an electronic device provided by an embodiment of the present invention.

[0080] See also Figure 4 As shown, Figure 4 The flowchart of the data management method provided by some embodiments of the present invention is shown.

[0081] S100: forming a device data body based on device data, wherein the device data body is device data stored in and associated with the electronic device.

[0082] See also Figure 6 , Figure 6 A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown. Specifically, an electronic device includes device data associated with itself.

[0083] S200: Sending device data to the cloud, so that the cloud forms a device data shadow based on the device data after receiving the device data, wherein the device data shadow is device data stored in the cloud and associated with the electronic device.

[0084] See also Figure 6 , Figure 6A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown.

Exemplarily, after forming a device data body, the electronic device sorts the device data body according to specific rules, uses a corresponding summary algorithm to extract key information from the device data body, refines and abstracts the device data body, and uses key target data to effectively represent the core information and features of the device data body, and then generates a device body summary in a standardized data format and structure. Among them, the device body summary is summary data generated by the electronic device based on the device data body, and the device body summary has a fixed length and unique data, and has a unique identification identifier. It can be understood that the device body summary has the ability to be updated in real time, and can be dynamically updated as the device data body changes, ensuring that the device body summary can timely and accurately reflect changes in the device data of the electronic device.

[0091] S304: receiving background data sent from the cloud, forming a background data shadow based on the background data, and generating a background shadow summary based on the background data shadow, wherein the background data shadow is background data stored in the electronic device and associated with the electronic device.

[0092] See also Figure 6 , Figure 6A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown. Specifically, during the initialization process of the electronic device, after sending the device data to the cloud, the cloud generates background data associated with the electronic device based on the device data, and then sends the background data to the electronic device safely and efficiently through a suitable transmission protocol and technology. The electronic device receives the background data sent by the cloud, and after receiving the background data, it organizes and cleans the received background data according to the preset coding rules and coding sequence, obtains a background data shadow of a standardized data format and structure, and stores the background data shadow in the electronic device. It can be understood that the background data shadow is the background data stored in the electronic device and associated with the electronic device. It should be understood that the background data shadow has the ability to update in real time, and can be dynamically updated as the background data of the electronic device in the cloud changes, ensuring that the background data shadow can timely and accurately reflect the changes in the background data of the electronic device.

[0093] Among them, the background data includes identification codes of resource data such as pictures, audio and video associated with the electronic device (such as guidance audio, advertising video, carousel pictures, etc.), control data such as volume, brightness and time of the electronic device (such as 50% volume, 70% screen brightness, 10s display time, etc.), configuration information data, and other related data.

[0094] After the background data shadow is formed, the background data shadow is sorted according to specific rules, and the corresponding summary algorithm is used to extract key information from the background data shadow, refine and abstract the background data shadow, and use the key target data to effectively represent the core information and features of the background data shadow, and then generate a background shadow summary with a standardized data format and structure. Among them, the background shadow summary is the summary data generated by the electronic device based on the background data shadow. The background shadow summary has a fixed length and unique data, and has a unique identification identifier. It can be understood that the background shadow summary has the ability to be updated in real time, and can be dynamically updated as the background data shadow changes, ensuring that the background shadow summary can timely and accurately reflect the changes in the background data of the electronic device.

[0095] S306: Send the device body summary and the background shadow summary to the cloud, so that after receiving the device body summary and the background shadow summary, the cloud updates the data based on the device body summary and the device shadow summary, and based on the background shadow summary and the background body summary, wherein the device shadow summary is the summary data generated by the cloud based on the device data shadow formed by the device data, and the background body summary is the summary data generated by the cloud based on the background data body formed by the background data.

[0096] See also Figure 6 , Figure 6A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown. Exemplarily, after the electronic device generates a device body summary and a background shadow summary, it sends the device body summary and the background shadow summary to the cloud securely and efficiently through a suitable transmission protocol and technology, so that after receiving the device body summary and the background shadow summary, the cloud determines whether to update the device data and / or background data based on the device body summary and the device shadow summary, as well as the background shadow summary and the background body summary. After determining that the device data and / or background data have changed, the device data and / or background data are updated. It can be understood that the device shadow summary is summary data generated by the cloud based on the device data shadow, and the device shadow summary has a fixed length and unique data, and has a unique identification identifier. The background body summary is summary data generated by the cloud based on the background data body formed by the background data, and the background body summary has a fixed length and unique data, and has a unique identification identifier.

[0097] In an embodiment of the present invention, if the cloud determines that there is a difference between the device body summary and the device shadow summary, it means that the device data body stored in the electronic device is different from the device data shadow stored in the cloud, and the device data of the electronic device has changed. The cloud sends a device data update instruction to the electronic device to notify the electronic device to send the updated device data to the cloud. The electronic device sends the updated device data to the cloud, so that the cloud updates the device data shadow according to the updated device data after receiving the updated device data, and updates the device shadow summary according to the updated device data shadow.

[0098] Accordingly, if the cloud determines that there is a difference between the background shadow summary and the background body summary, it means that the background data shadow stored in the electronic device is different from the background data body stored in the cloud, and the background data of the electronic device has changed. The cloud sends a background data update instruction to the electronic device to notify the electronic device to obtain the updated background data and update the current background data of the electronic device. The electronic device receives the updated background data sent by the cloud, and after receiving the updated background data, updates the background data shadow according to the updated background data, and updates the background shadow summary according to the updated background data shadow.

[0099] By sending the device body summary and the background shadow summary to the cloud, the cloud can determine whether the device data and / or background data have changed based on the device body summary and the device shadow summary, as well as the background shadow summary and the background body summary after receiving the device body summary and the background shadow summary. After determining that the device data and / or background data have changed, the device data and / or background data are updated. Thus, unnecessary traffic consumption can be reduced or even avoided, reducing traffic waste.

[0100] In some embodiments, after determining that the device data of the electronic device has changed, the cloud sends a device data update instruction to the electronic device, notifying the electronic device to send the updated device data to the cloud, so that the cloud updates the current device data of the electronic device stored in the cloud.

[0101] Specifically, the data management method further includes but is not limited to the following steps S308:

[0102] S308: In response to receiving a device data update instruction sent by the cloud, send updated device data of the electronic device to the cloud, so that the cloud updates the device data shadow based on the updated device data after receiving the updated device data, and updates the device shadow summary based on the updated device data shadow, wherein the device data update instruction is sent to the electronic device when the cloud compares and determines that the device body summary and the device shadow summary are different.

[0103] Specifically, when the cloud determines that the device body digest and the device shadow digest are different, the cloud sends a device data update instruction to the electronic device to notify the electronic device to send the updated device data to the cloud. The electronic device receives the device data update instruction sent by the cloud, and in response to the received device data update instruction, sends the updated device data of the electronic device to the cloud, so that after receiving the updated device data of the electronic device, the cloud updates the device data shadow according to the updated device data of the electronic device, and updates the device shadow digest according to the updated device data shadow. Obviously, when the cloud determines that the device body digest and the device shadow digest are different after comparison, the cloud sends the device data update instruction to the electronic device.

[0104] Specifically, after the cloud receives the updated device data, it organizes and cleans the received updated device data according to the preset coding rules and coding sequence to obtain an updated device data shadow with a standardized data format and structure, and stores the updated device data shadow in a corresponding storage module in the cloud.

[0105] After completing the update of the device data shadow, the cloud will sort the updated device data shadow according to specific rules, use the corresponding summary algorithm to extract key information from the updated device data shadow, refine and abstract the updated device data shadow, and use key target data to effectively represent the core information and features of the updated device data shadow, and then generate an updated device shadow summary with standardized data format and structure, and store the updated device shadow summary in the corresponding storage module of the cloud.

[0106] In some embodiments, after determining that the background data of the electronic device has changed, the cloud sends a background data update instruction to the electronic device, notifying the electronic device to obtain updated background data from the cloud to update the current background data stored in the electronic device.

[0107] Specifically, the data management method also includes but is not limited to the following steps S310:

[0108] S310: In response to the background data update instruction received from the cloud, the updated background data of the electronic device is obtained from the cloud, and the current background data of the electronic device is updated, wherein the background data update instruction is sent to the electronic device when the cloud compares and determines that the background shadow summary and the background body summary are different.

[0109] Specifically, when the cloud determines that the background body summary and the background shadow summary are different, the cloud sends a background data update instruction to the electronic device, notifying the electronic device to obtain the updated background data of the electronic device from the cloud, and update the current background data of the electronic device. The electronic device receives the background data update instruction sent by the cloud, and in response to the received background data update instruction, obtains the updated background data of the electronic device from the cloud, and updates the current background data of the electronic device. That is, the electronic device updates the background data shadow according to the updated background data, and updates the background shadow summary according to the updated background data shadow. It should be understood that when the cloud determines that the device body summary and the device shadow summary are different after comparison, the cloud sends the background data update instruction to the electronic device.

[0110] In some embodiments, obtaining updated background data of the electronic device and updating the current background data of the electronic device specifically includes but is not limited to the following steps S3101-S3102:

[0111] S3101: Send a background data update request instruction to the cloud, so that the cloud sends the updated background data of the electronic device to the electronic device after receiving the background data update request instruction.

[0112] S3102: Receive updated background data sent by the cloud, update the background data shadow based on the updated background data, and update the background shadow summary based on the updated background data shadow.

[0113] Specifically, the electronic device sends an update background data request instruction to the cloud to request the cloud to send the update background data of the electronic device to the electronic device. That is, after receiving the update background data request instruction, the cloud sends the update background data of the electronic device to the electronic device in response to the received update background data request instruction.

[0114] The cloud sends the updated background data of the electronic device to the electronic device, and the electronic device receives the updated background data sent by the cloud. After receiving the updated background data of the electronic device sent by the cloud, that is, after obtaining the updated background data of the electronic device, the electronic device organizes and cleans the received updated background data according to the preset coding rules and coding sequence, obtains the updated background data shadow with standardized data format and structure, and stores the updated background data shadow in the corresponding storage module of the electronic device.

[0115] After completing the update of the background data shadow, the electronic device sorts the updated background data shadow according to specific rules, uses the corresponding summary algorithm to extract key information from the updated background data shadow, refines and abstracts the updated background data shadow, and uses key target data to effectively represent the core information and features of the updated background data shadow, and then generates an updated background shadow summary in a standardized data format and structure, and stores the updated background shadow summary in the corresponding storage module of the electronic device.

[0116] In some embodiments, the electronic device includes resource data, such as video ads, carousel images, and guidance audio, etc. Each resource data has a corresponding identification code, and the identification code is used to uniquely represent the corresponding resource data. Among them, the background data of the electronic device includes the identification code of the resource data, and the electronic device can download the corresponding resource data from the cloud according to the identification code of the resource data.

[0117] If the identification code of the resource data in the updated background data changes, the electronic device can download the resource data corresponding to the identification code of the resource data from the cloud according to the identification code of the resource data included in the updated background data, thereby obtaining the updated resource data of the electronic device.

[0118] Specifically, the data management method further includes but is not limited to the following steps S312:

[0119] S312: Based on the current background data of the electronic device and the identification code of the resource data in the updated background data, the updated resource data of the electronic device is obtained to update the current resource data of the electronic device.

[0120] Specifically, if the identification code of the resource data in the updated background data of the electronic device changes, it means that the resource data in the electronic device needs to be updated. The electronic device obtains the identification code of the resource data in the current background data and the updated background data of the electronic device, and compares the identification code of the resource data in the current background data with the identification code of the resource data in the updated background data to determine the difference in the identification code of the resource data between the two. Then, according to the difference in the identification code of the resource data in the current background data and the updated background data, the relevant resource data acquisition instruction is sent to the cloud to obtain the updated resource data corresponding to the identification code of the resource data, and update the current resource data of the electronic device.

[0121] In some embodiments, the obtaining of the updated resource data of the electronic device based on the current background data of the electronic device and the identification code of the resource data in the updated background data to update the current resource data of the electronic device specifically includes but is not limited to the following steps S3121-S3125:

[0122] S3121: Acquire a first identification code set of resource data in current background data of the electronic device and a second identification code set of resource data in updated background data of the electronic device respectively.

[0123] S3122: Obtain the intersection of the first identification code set and the second identification code set.

[0124] S3123: Obtain a first difference set between the first identification code set and the intersection set, and obtain a second difference set between the second identification code set and the intersection set.

[0125] Specifically, for the current background data and updated background data of the electronic device, the first identification code of the resource data in the current background data is obtained, and the second identification code of the resource data in the updated background data is obtained. Then the first identification codes of the resource data are combined to form a first identification code set, and the second identification codes of the resource data constitute a second identification code set. For example, the first identification codes of the resource data in the current background data are obtained as: a1, a2, a3, a4, which are combined to form a first identification code set A = {a1, a2, a3, a4}; the second identification codes of the resource data in the updated background data are: a3, a4, a5, a6, which are combined to form a second identification code set B = {a3, a4, a5, a6}. It should be understood that different identification codes of resource data can be set according to actual application conditions, and the embodiments of the present invention do not impose any limitations on this.

[0126] After the first identification code set A and the second identification code set B are formed by combination, the intersection between the first identification code set A and the second identification code set B can be calculated through simple set operations, that is, C=A∩B={a3, a4}.

[0127] After calculating the intersection between the first identification code set and the second identification code set, the first difference set D between the first identification code set A and the intersection set C can be calculated by simple set operations, that is, D=AC={a1, a2}. And the second difference set E between the second identification code set B and the intersection set C can be calculated, that is, E=BC={a5, a6}.

[0128] S3124: Delete the resource data corresponding to the identification code in the first difference set from the current resource data of the electronic device, and obtain the resource data corresponding to the identification code in the second difference set from the cloud.

[0129] S3125: The resource data corresponding to the identification code in the intersection set and the resource data corresponding to the identification code in the second difference set are used to form updated resource data of the electronic device, so as to complete the updating of the current resource data of the electronic device.

[0130] Exemplarily, after determining the first difference set D between the first identification code set A and the intersection C, and determining the second difference set E between the second identification code set B and the intersection C, the current resource data of the electronic device can be updated according to the identification codes of the resource data included in the first difference set D and the second difference set E.

[0131] Specifically, the electronic device deletes the resource data corresponding to the identification code (i.e., a1, a2) of the resource data in the first difference set D from the current resource data of the electronic device based on the identification code of the resource data in the first difference set D, retains the resource data corresponding to the identification code (i.e., a3, a4) of the resource data in the intersection C, and then sends relevant resource data acquisition instructions to the cloud to acquire the resource data corresponding to the identification code (i.e., a5, a6) of the resource data in the second difference set E from the cloud.

[0132] The electronic device then combines the resource data corresponding to the identification code (i.e., a3, a4) of the resource data in the intersection C retained in the current resource data of the electronic device and the resource data corresponding to the identification code (i.e., a5, a6) of the resource data in the obtained second difference set E to form the updated resource data of the electronic device, thereby completing the update of the current resource data of the electronic device.

[0133] In this embodiment, by retaining the resource data corresponding to the identification code that has not changed (i.e., the identification code of the resource data included in both the current background data and the updated background data), deleting the resource data corresponding to the identification code that has changed (i.e., the identification code of the resource data not included in the updated background data), and then obtaining the resource data corresponding to the identification code that has changed (i.e., the identification code of the resource data not included in the current background data) from the cloud, unnecessary process transmission can be reduced and traffic waste can be avoided.

[0134] It can be understood that if the intersection C is an empty set, that is, there is no identification code for the resource data, it means that there is no resource data that needs to be retained; if the first difference set D is an empty set, that is, there is no identification code for the resource data, it means that there is no resource data that needs to be deleted; if the second difference set E is an empty set, that is, there is no identification code for the resource data, it means that there is no resource data that needs to be acquired.

[0135] In summary, the data management method provided by the embodiment of the present invention is used for an electronic device, wherein the electronic device includes device data, and the method includes: forming a device data body based on the device data, wherein the device data body is device data stored in the electronic device and associated with the electronic device; sending the device data to the cloud, so that after receiving the device data, the cloud forms a device data shadow based on the device data, wherein the device data shadow is device data stored in the cloud and associated with the electronic device.

[0136] In the data management method provided by the embodiment of the present invention, the electronic device directly sends the device data to the cloud, and forms a device data shadow in the cloud, so that the docking system does not need to obtain the device data through the gateway device, and can directly obtain the device data shadow stored in the cloud. This facilitates the unified management of electronic devices, simplifies the acquisition process, improves efficiency, reduces the impact on network stability, improves response speed, and increases concurrency.

[0137] The following describes in detail the data management method applied to the cloud in some embodiments of the present invention.

[0138] See also Figure 5 As shown, Figure 5 The flowchart of the data management method provided by some embodiments of the present invention is shown. The data management method provided by the embodiment of the present invention can be applied to the above-mentioned cloud, and the data management method includes but is not limited to the following steps S400:

[0139] S400: receiving device data sent by an electronic device, and forming a device data shadow based on the device data, wherein the device data shadow is device data stored in the cloud and associated with the electronic device.

[0140] See also Figure 6 , Figure 6A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown. Specifically, the cloud receives device data sent by an electronic device through a preset endpoint for receiving device data. After receiving the device data, the received device data is sorted and cleaned according to the preset coding rules and coding order to obtain a device data shadow of a standardized data format and structure, and the device data shadow is stored in the corresponding storage module of the cloud to ensure effective storage of the device data shadow. It can be understood that the device data shadow is device data stored in the cloud and associated with the electronic device. Among them, the device data includes the unique identity of the electronic device, location information, hardware specifications, software configuration, network configuration and other related data. It is easy to understand that the device data shadow and the device data body include the same device data associated with the electronic device, the only difference is that the device data shadow is stored in the cloud and the device data body is stored in the electronic device. By forming the device data shadow in the cloud, the docking system does not need to indirectly obtain the device data through other devices (such as gateway devices), and can directly obtain the device data shadow stored in the cloud. Thereby facilitating the unified management of electronic devices, simplifying the acquisition process, improving efficiency, reducing the impact of network stability, improving response speed, and increasing concurrency.

[0141] The data management method provided in the embodiment of the present invention is used in the cloud, and the method includes: receiving device data sent by an electronic device, and forming a device data shadow based on the device data, wherein the device data shadow is device data stored in the cloud and associated with the electronic device. The data management method provided in the embodiment of the present invention directly receives the device data sent by the electronic device in the cloud, and forms a device data shadow in the cloud, so that the docking system does not need to obtain the device data through other devices, and can directly obtain the device data shadow stored in the cloud. Thereby, it is convenient to uniformly manage electronic devices, simplify the acquisition process, improve efficiency, reduce the impact of network stability, improve response speed, and increase concurrency.

[0142] In some embodiments, in order to avoid unnecessary traffic consumption and reduce traffic waste, after receiving the device body summary and background shadow summary sent by the electronic device, the cloud determines whether the device data and / or background data have changed based on the device body summary and device shadow summary, as well as the background shadow summary and background body summary. After determining that the device data and / or background data have changed, the device data and / or background data are updated.

[0143] Specifically, the data management method also includes but is not limited to the following steps S402-S408:

[0144] S402: Generate a device shadow summary based on the device data shadow.

[0145] See also Figure 6 , Figure 6 A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown. Exemplarily, after forming a device data shadow, the cloud sorts the device data shadow according to specific rules, uses a corresponding summary algorithm to extract key information from the device data shadow, refines and abstracts the device data shadow, and uses key target data to effectively represent the core information and features of the device data shadow, and then generates a device shadow summary in a standardized data format and structure. Among them, the device shadow summary is summary data generated by the cloud based on the device data shadow, and the device shadow summary has a fixed length and unique data, and has a unique identification identifier. It can be understood that the device shadow summary has the ability to be updated in real time, and can be dynamically updated as the device data shadow changes, ensuring that the device shadow summary can timely and accurately reflect changes in the device data of the electronic device.

[0146] S404: forming a background data ontology based on the background data, and generating a background ontology summary based on the background data ontology, wherein the background data ontology is background data stored in the cloud and associated with the electronic device.

[0147] See also Figure 6 , Figure 6 A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown. Specifically, after receiving the device data sent by the electronic device, the cloud generates background data associated with the electronic device according to the device data, and then organizes and cleans the background data according to the preset coding rules and coding sequence to obtain a background data body with a standardized data format and structure, and stores the background data body in a corresponding storage module in the cloud to ensure effective storage of the background data body. It can be understood that the background data body is the background data stored in the cloud and associated with the electronic device.

[0148] Among them, the background data includes the identification codes of resource data such as pictures, audio and video associated with the electronic device (such as guidance audio, advertising video, carousel pictures, etc.), the volume, brightness and time control data of the electronic device (such as 50% volume, 70% screen brightness, 10s display time, etc.), configuration information data, and other related data, etc. It can be understood that the background data body has the ability to be updated in real time, and can be dynamically updated as the background data of the electronic device in the cloud changes, ensuring that the background data body can timely and accurately reflect the changes in the background data of the electronic device.

[0149] After the background data ontology is formed, the background data ontology is sorted according to specific rules, and the corresponding summary algorithm is used to extract key information from the background data ontology, refine and abstract the background data ontology, and use key target data to effectively represent the core information and features of the background data ontology, and then generate a background ontology summary with standardized data format and structure. Among them, the background ontology summary is the summary data generated by the cloud based on the background data ontology. The background ontology summary has a fixed length and unique data, and has a unique identification. It can be understood that the background ontology summary has the ability to be updated in real time, and can be dynamically updated as the background data ontology changes, ensuring that the background ontology summary can timely and accurately reflect the changes in the background data of the electronic device.

[0150] S406: Sending background data to the electronic device, so that after receiving the background data, the electronic device forms a background data shadow based on the background data, and generates a background shadow summary based on the background data shadow.

[0151] See also Figure 6 , Figure 6 A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown. Specifically, the cloud sends background data to an electronic device safely and efficiently through a suitable transmission protocol and technology, so that after receiving the background data, the electronic device forms a background data shadow according to the background data, and generates a background shadow summary according to the background data shadow, and stores the background data shadow and the background shadow summary in the electronic device. In some embodiments, an endpoint for receiving background data in an electronic device can be pre-set, and a corresponding storage module can be set in the electronic device to effectively store the background data shadow. Among them, the storage module can be a database, a distributed storage system or other suitable data storage scheme. It can be understood that the background data shadow is the background data stored in the electronic device and associated with the electronic device. It should be understood that the background data shadow and the background data body include the same background data associated with the electronic device, and the difference is only that the background data shadow is stored in the electronic device and the background data body is stored in the cloud.

[0152] S408: Receive a device body summary and a background shadow summary sent by the electronic device, and determine to update data based on the device body summary and the device shadow summary, and based on the background shadow summary and the background body summary, wherein the background shadow summary is summary data generated by the electronic device based on a background data shadow formed by the background data, and the device body summary is summary data generated by the electronic device based on a device data body formed by the device data.

[0153] See also Figure 6 , Figure 6A schematic diagram of data generation and summary comparison in a data management method provided by some embodiments of the present invention is shown. Specifically, the electronic device sends a device body summary and a background shadow summary to the cloud securely and efficiently through a suitable transmission protocol and technology, and the cloud receives the device body summary and the background shadow summary. After receiving the device body summary and the background shadow summary, the cloud determines whether to update the device data and / or background data based on the device body summary and the device shadow summary, as well as the background shadow summary and the background body summary. After determining that the device data and / or background data have changed, the device data and / or background data are updated. It can be understood that the background shadow summary is the summary data generated by the electronic device based on the background data shadow formed by the background data, and the background shadow summary has a fixed length and unique data, and has a unique identification identifier. The device body summary is the summary data generated by the electronic device based on the device data body formed by the device data, and the device body summary has a fixed length and unique data, and has a unique identification identifier.

[0154] In an embodiment of the present invention, if the cloud determines that there is a difference between the device body summary and the device shadow summary, it means that the device data body stored in the electronic device is different from the device data shadow stored in the cloud, and the device data of the electronic device has changed. The cloud sends a device data update instruction to the electronic device to notify the electronic device to send the updated device data to the cloud. After receiving the updated device data, the cloud updates the device data shadow according to the updated device data, and updates the device shadow summary according to the updated device data shadow.

[0155] Accordingly, if the cloud determines that there is a difference between the background shadow summary and the background body summary, it means that the background data shadow stored in the electronic device is different from the background data body stored in the cloud, and the background data of the electronic device has changed. The cloud sends a background data update instruction to the electronic device to notify the electronic device to obtain the updated background data and update the current background data of the electronic device. The cloud sends the updated background data to the electronic device, so that after receiving the updated background data, the electronic device updates the background data shadow according to the updated background data, and updates the background shadow summary according to the updated background data shadow.

[0156] By sending the device body summary and the background shadow summary to the cloud, after receiving the device body summary and the background shadow summary, the cloud determines whether the device data and / or the background data have changed according to the device body summary and the device shadow summary, and according to the background shadow summary and the background body summary. After determining that the device data and / or the background data have changed, the device data and / or the background data are updated. Thus, unnecessary traffic consumption can be reduced or even avoided, reducing traffic waste.

[0157] In some embodiments, data is updated based on the device entity summary and the device shadow summary, and based on the background shadow summary and the background entity summary, including but not limited to the following steps S4082-S4084:

[0158] S4082: Compare the device body summary and the device shadow summary. If the device body summary and the device shadow summary are different, send a device data update instruction to the electronic device, so that the electronic device sends the updated device data of the electronic device to the cloud after receiving the device data update instruction.

[0159] Specifically, after the cloud receives the device body summary and the background shadow summary, the device body summary and the device shadow summary are found according to the unique identification identifiers of the device body summary and the device shadow summary, and then the device body summary and the device shadow summary are compared to determine whether the device data associated with the electronic device has changed. Among them, if the device body summary and the device shadow summary are the same, it means that the device data body stored in the electronic device and the device data shadow stored in the cloud are the same, the device data associated with the electronic device has not changed, and there is no need to update the device data associated with the electronic device stored in the cloud. If the device body summary and the device shadow summary are different, it means that the device data body stored in the electronic device and the device data shadow stored in the cloud are different, the device data associated with the electronic device has changed, and it is necessary to update the device data associated with the electronic device stored in the cloud.

[0160] If the device body summary and the device shadow summary are different, it means that the device data associated with the electronic device has changed, and the cloud sends a device data update instruction to the electronic device, so that the electronic device sends the updated device data of the electronic device to the cloud after receiving the device data update instruction. After receiving the updated device data of the electronic device, the cloud updates the current device data of the electronic device according to the updated device data.

[0161] S4084: Receive updated device data sent by the electronic device, update the device data shadow based on the updated device data, and update the device shadow summary based on the updated device data shadow.

[0162] Specifically, after the cloud receives the updated device data of the electronic device, it organizes and cleans the received updated device data according to the preset coding rules and coding sequence, obtains the updated device data shadow with standardized data format and structure, and stores the updated device data shadow to the corresponding storage module of the cloud.

[0163] After completing the update of the device data shadow, the cloud will sort the updated device data shadow according to specific rules, use the corresponding summary algorithm to extract key information from the updated device data shadow, refine and abstract the updated device data shadow, and use key target data to effectively represent the core information and characteristics of the updated device data shadow, and then generate an updated device shadow summary with standardized data format and structure.

[0164] In some embodiments, data is updated based on the device entity summary and the device shadow summary, and based on the background shadow summary and the background entity summary, including but not limited to the following steps S4086-S4088:

[0165] S4086: Compare the background shadow summary and the background body summary. If the background shadow summary and the background body summary are different, send a background data update instruction to the electronic device.

[0166] Exemplarily, if the device body summary and the device shadow summary are the same, it means that the device data associated with the electronic device has not changed, and there is no need to update the device data associated with the electronic device stored in the cloud. The cloud finds the background shadow summary and the background body summary according to the unique identification identifier of the background shadow summary and the background body summary, and then compares the background shadow summary with the background body summary to determine whether the background data associated with the electronic device has changed. Among them, if the background shadow summary and the background body summary are the same, it means that the background data shadow stored in the electronic device and the background data body stored in the cloud are the same, the background data associated with the electronic device has not changed, and there is no need to update the background data associated with the electronic device stored in the cloud. If the background shadow summary and the background body summary are different, it means that the background data shadow stored in the electronic device and the background data body stored in the cloud are different, the background data associated with the electronic device has changed, and the background data associated with the electronic device stored in the electronic device needs to be updated.

[0167] If the background shadow summary and the background body summary are different, it means that the background data associated with the electronic device has changed. The cloud sends a background data update instruction to the electronic device, so that after receiving the background data update instruction, the electronic device obtains the updated background data of the electronic device from the cloud and updates the current background data of the electronic device.

[0168] S4088: In response to a background data update request instruction received from the electronic device, the background data update of the electronic device is sent to the electronic device, so that after receiving the background data update, the electronic device updates the background data shadow based on the background data update, and updates the background shadow summary based on the updated background data shadow.

[0169] The cloud sends a background data update instruction to the electronic device, notifying the electronic device to obtain the updated background data of the electronic device from the cloud, and update the current background data of the electronic device. In response to the received background data update instruction, the electronic device obtains the updated background data of the electronic device from the cloud, and updates the current background data of the electronic device.

[0170] Specifically, the electronic device sends an update background data request instruction to the cloud, requesting to obtain the update background data of the electronic device from the cloud. The cloud receives the update background data request instruction sent by the electronic device, and in response to the received update background data request instruction, sends the update background data of the electronic device to the electronic device, so that after receiving the update background data, the electronic device updates the background data shadow according to the update background data, and updates the background shadow summary according to the updated background data shadow.

[0171] Specifically, after the electronic device receives the updated background data of the electronic device sent from the cloud, that is, after obtaining the updated background data of the electronic device, the electronic device organizes and cleans the received updated background data according to preset coding rules and coding sequence, obtains an updated background data shadow with standardized data format and structure, and stores the updated background data shadow to the corresponding storage module of the electronic device.

[0172] After completing the update of the background data shadow, the electronic device sorts the updated background data shadow according to specific rules, uses the corresponding summary algorithm to extract key information from the updated background data shadow, refines and abstracts the updated background data shadow, and uses key target data to effectively represent the core information and features of the updated background data shadow, and then generates an updated background shadow summary in a standardized data format and structure, and stores the updated background shadow summary in the corresponding storage module of the electronic device.

[0173] In summary, the data management method provided in the embodiment of the present invention is used in the cloud, and the method includes: receiving device data sent by an electronic device, and forming a device data shadow based on the device data, wherein the device data shadow is device data stored in the cloud and associated with the electronic device. In the data management method provided in the embodiment of the present invention, the cloud directly receives device data sent by an electronic device, and forms a device data shadow in the cloud, so that the docking system does not need to obtain device data through other devices, and can directly obtain the device data shadow stored in the cloud. Thereby, it is convenient to uniformly manage electronic devices, simplify the acquisition process, improve efficiency, reduce the impact of network stability, improve response speed, and increase concurrency.

[0174] The following briefly describes the data management method provided by the embodiment of the present invention using a simple embodiment.

[0175] See also Figure 7 As shown, Figure 7 The logical timing diagram of the data management method provided by some embodiments of the present invention is shown. The electronic device is an Android device with a network card, the Android version is greater than 12.0, and the API is greater than 34.0. The Android device has the functions of timed power on and off, adjusting the volume, storing data, displaying data, and interacting with other devices. The cloud is a cloud server that provides a management background and is responsible for communicating directly with the Android device. It can also communicate with other docking systems to perform signal transmission and data interaction.

[0176] In the embodiment described below, the Android device is located in a display cabinet of a certain store, and the cloud server is connected to the Android device through a network. The cloud server can set connection information, device information, verification information, etc. of the Android device for the Android device.

[0177] In this embodiment, the Android device is installed in a fixed position of the product display rack, powered on, and then the Wi-Fi connection function of the Android device is turned on to connect to the Internet to communicate with the cloud server.

[0178] Android devices have deeply customized systems. After the Android device is started, open the self-developed application and set the data for connecting to the cloud server (i.e., set the connection information) in the application. The connection information includes but is not limited to: the cloud server IP address, cloud server port, the country, city, store where the Android device is located, the language used by the Android device, and an alias for distinguishing, etc. It should be understood that the connection information of the Android device can be set before assembly or modified later.

[0179] After the connection information is set, the Android device starts to check the device information, including but not limited to: the unique device identifier (usually the MAC address of the network card), whether Wi-Fi is turned on, whether Bluetooth is turned on, whether infrared sensing is turned on, current volume, current brightness, whether the scheduled power on / off is turned on, and the scheduled power on / off time.

[0180] The self-developed application in the Android device determines whether the device data has been submitted to the cloud server for initialization. If it has not been submitted, it sorts its own device data according to the rules and sends the device data to the cloud server through the aforementioned steps of setting the connection information. Among them, the Android device forms a device data body based on the device data, and generates a device body summary based on the device data body.

[0181] When the cloud server receives the device data from the Android device, it first determines whether the unique identifier of the Android device has been entered in the management background. If it has been entered, it is considered to be a legitimate Android device. Otherwise, it will directly return the feedback information of "Failed to initialize the device, the device is illegal".

[0182] After receiving the feedback information, the Android device determines whether to enter the management backend. If it is an illegal device, a notification prompt will pop up to inform the administrator. At this time, the administrator can enter the unique identifier of the Android device in the management backend, and the Android device will resend the device data to the cloud server.

[0183] If it is a legitimate device, the cloud server receives the device data of the Android device, and sets the background data corresponding to the Android device according to the device data of the Android device. The priority of the background data is as follows: background data set for this device alone> device background data of the store set by the device> device background data of the city set by the device> device background data of the country set by the device> default background data. Among them, the background data at least includes the categories displayed by the device, the products under the device categories, the detailed information of the products, the identification codes of the pictures, videos and audios (i.e., resource data) in the detailed information of the products, the volume and brightness of the device, whether the infrared sensor is turned on, the identification code of the resource data played when the infrared sensor is unattended (such as video ads, carousel pictures, guidance audio, etc.), the power on and off time, the identification code of the resource data played when the infrared sensor is triggered, etc. After setting the background data, the cloud server forms the background data body based on the background data, and generates the background body summary based on the background data body. And the device data shadow is formed based on the device data, and the device shadow summary is generated based on the device data shadow.

[0184] The cloud server sends background data to the Android device. After the Android device receives the background data sent by the cloud server, it forms a background data shadow based on the background data, and generates a background shadow summary based on the background data shadow. Then the Android device obtains the corresponding resource data from the cloud server according to the identification code of the resource data in the background data, and stores it in the storage module corresponding to the Android device. At this point, the Android device completes initialization.

[0185] The Android device sends the background shadow summary and the device body summary to the cloud server in a polling manner. If the device data of the Android device changes, the cloud server compares and determines that the updated device body summary sent to the cloud server is different from the device shadow summary stored in the cloud server, and the Android device updates the device data body and the device body summary. The cloud server sends a device data update instruction to the Android device, requesting the Android device to send updated device data, that is, the latest device data.

[0186] After receiving the device data update instruction, the Android device sends the updated device data of the Android device to the cloud server. After receiving the updated device data, the cloud server updates the device data shadow according to the updated device data, and updates the device shadow summary.

[0187] If the device data of the Android device has not changed, the cloud server compares and determines that the device body digest sent to the cloud server is the same as the device shadow digest stored in the cloud server, and the Android device does not update the device data body and device body digest. The cloud server compares the background shadow digest sent to the cloud server with the background body digest stored in the cloud server to see if they are the same.

[0188] Among them, changes in device data include: turning on / off infrared sensing, changing the power on / off time, adjusting the volume, etc. The application scenarios of infrared sensing are as follows: when the infrared sensing function is turned on, in the self-developed application, when someone approaches the Android device, the infrared sensing module of the Android device will trigger the playback of audio (greeting audio, guidance audio, etc.) and then jump to the product classification page so that customers can understand the product; when the customer leaves the Android device, the infrared sensing module does not sense someone approaching the Android device for a continuous period of time, then the program will automatically play product introduction advertising videos, carousel pictures, etc. When the infrared sensing switches between off and on, the device data of the Android device changes.

[0189] When other docking systems need to obtain device data of Android devices, the docking system can connect to the cloud server, and then the cloud server provides the device data shadow to the docking system. In this way, if there are multiple docking systems frequently obtaining device data, the pressure on the sending device of Android devices can be greatly reduced, and the docking system does not need to indirectly obtain the device data of Android devices through other devices. Similarly, if the system administrator is doing promotion activities in a certain area and needs to modify the background data of Android devices in batches, the device background data of the area can be changed in the management end background, such as product classification, product classification cover image, product detailed content, etc.

[0190] If the background data of the Android device changes, the cloud server compares and determines that the updated background body summary stored in the cloud server is different from the background shadow summary sent to the cloud server, and the cloud server updates the background data body and the background body summary. The cloud server sends a background data update instruction to the Android device to instruct the Android device to obtain the updated background data of the Android device, that is, the latest background data.

[0191] After receiving the background data update instruction, the Android device sends an update background data request instruction to the cloud server to request to obtain the update background data of the Android device. After receiving the update background data request instruction, the cloud server sends the update background data to the Android device in response to the update background data request instruction. After receiving the update background data, the Android device updates the background data shadow according to the update background data, and updates the background shadow summary. At this time, if the background data changes and involves the change of the identification code of the resource data, that is, the resource data of the Android device needs to be updated. According to the difference between the identification code of the resource data in the current background data and the update background data, the Android device sends the relevant update resource data acquisition instruction to the cloud server to request to obtain the update resource data. After receiving the relevant update resource data acquisition instruction, the cloud server sends the update resource data to the Android device, and the Android device receives the update resource data and updates the current resource data of the Android device. At this point, the resource data update of the Android device is completed.

[0192] If the background data of the Android device has not changed, the cloud server compares and determines that the updated background body summary stored in the cloud server is the same as the background shadow summary sent to the cloud server, and the cloud server does not update the background data body and the background body summary.
