Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

With the development of intelligent technology, intelligent devices are widely popularized. In the application scene of the intelligent equipment, higher requirements are put forward on interconnection and intercommunication among the intelligent equipment and data synchronization so as to require that the functional linkage of multiple intelligent equipment is realized through the data synchronization among the intelligent equipment, thereby creating a more intelligent scene based on the intelligent equipment. For example, the function linkage of synchronous display of screen end data of the multi-screen terminal is realized by depending on data synchronization among the multi-screen terminals, the function linkage of nearby awakening of the intelligent sound is realized by depending on data synchronization among the plurality of intelligent sound.

In the related art, the following two ways are generally adopted to realize data synchronization between intelligent devices: (1) Data synchronization between intelligent devices is carried out through a local area network; (2) And forwarding the data to be synchronized through a device management unit (such as a cloud server, a terminal provided with a device management application program and the like) so as to realize data synchronization among intelligent devices.

Taking the smart home field as an example, referring to fig. 1a, in a network topology structure of a single local area network, an intelligent device a and an intelligent device B located at the same level are connected with a home router, and the intelligent device a and the intelligent device B are located in the local area network constructed by the home router. The intelligent device A can discover the intelligent device B through the local area network, and can synchronize data with the intelligent device B through the local area network by utilizing broadcasting or point-to-point communication and other modes.

The mode of carrying out data synchronization among intelligent devices through the local area network has the advantages of high response speed and no influence on the uplink network speed, but has strict requirements on the network connection topological structure among the intelligent devices, namely, the intelligent devices which need to carry out data synchronization are all installed in the same local area network. According to the interception mechanism of the router, the intelligent devices in one local area network can only perform data transmission with the devices in the same level in the same local area network, so that if the intelligent devices needing to perform data synchronization are respectively installed in different local area networks, the mechanism of performing device discovery and data synchronization by depending on the local area network among the intelligent devices fails. Taking the smart home field as an example, referring to fig. 1B, the smart device a is connected to a WIFI router, and the WIFI router and the smart device B are located at the same level and are both connected to a home router. The intelligent device A is located in a local area network 1 constructed by a WIFI router, and the WIFI router and the intelligent device B are located in a local area network 2 constructed by a home router. It can be understood that according to the interception mechanism of the router, the intelligent device a cannot perform data transmission with the intelligent device B across the local area network, so that the intelligent device a cannot discover the intelligent device B through the local area network 1 and perform data synchronization with the intelligent device B; likewise, the smart device B may perform data transmission with the router 1 located at the same level in the local area network 2, but cannot perform data transmission with the smart device a across the local area network, so that the smart device B may discover the WIFI router through the local area network 2 and perform data synchronization with the WIFI router, but cannot discover the smart device a through the local area network 2 and perform data synchronization with the smart device a.

Due to the widespread popularity of smart devices, more than one router is usually arranged in the application scenario of smart devices nowadays, and the scenario of deploying smart devices across a local area network is very common. Under a complex network topology structure, the technical scheme of device discovery and data synchronization by relying on a local area network cannot meet the data synchronization requirement of a cross-local area network, so that the data synchronization among intelligent devices is widely performed in a cloud synchronization mode in the related art, namely, the data synchronization among the intelligent devices is realized in a mode of performing data forwarding through device management units such as a cloud server.

Taking the field of smart home as an example, referring to fig. 1c, a smart home system of a family includes a smart device, a router, and a cloud server. The intelligent device A is located in a local area network constructed by the WIFI router 1, the intelligent device B is located in a local area network constructed by the WIFI router 2, and the WIFI router 1 and the WIFI router 2 are connected with a home router and used for accessing a network of a communication operator. The intelligent device A and the intelligent device B are connected to the same intelligent home or the same home account in the cloud server, so that the cloud server can serve as a device management unit to manage the intelligent device A and the intelligent device B. When the intelligent device A needs to synchronize data with the intelligent device B, the intelligent device A uploads the data to be synchronized to the cloud server through the WIFI router 1 and the home router, and the data to be synchronized is forwarded by depending on a data forwarding function of the cloud server so as to be forwarded to the intelligent device B through the home router and the WIFI router 2.

The method can be suitable for all network topological structures among intelligent devices, and even if the intelligent devices are positioned in the same local area network, the data forwarding among the intelligent devices can be carried out by adopting the method. Referring to fig. 1d, both the intelligent device a and the intelligent device B are located in a local area network constructed by a WIFI router 1, where the WIFI router 1 is connected to a home router for accessing a network of a communications carrier. When the intelligent device A needs to synchronize data with the intelligent device B, the intelligent device A uploads the data to be synchronized to the cloud server through the WIFI router 1 and the home router, and the data to be synchronized is forwarded by depending on a data forwarding function of the cloud server, so that the cloud server forwards the data to the intelligent device B through the home router and the WIFI router 1.

However, the forwarding link is longer, the data synchronization speed is slower, the burden of the cloud server is increased, and the load of the cloud server is required to be higher. Meanwhile, as the intelligent equipment can continuously upload data to the cloud server through the external network of the communication carrier accessed by the home router, the bandwidth of the uplink network of the intelligent home system can be occupied, the speed of the home network is influenced, and the delay of data synchronization is larger.

In order to effectively improve the efficiency of data synchronization between intelligent devices and reduce the dependence on the network topology structure between the intelligent devices, it is necessary to propose a data synchronization method, a data synchronization device, an electronic device and a computer readable storage medium. By establishing a set of rule switching logic for automatically selecting a data synchronization mechanism, if intelligent devices needing to perform data synchronization are all located in the same local area network, the data synchronization mechanism for performing data synchronization through the local area network can be automatically selected; if part of intelligent equipment needing to be synchronized is located in different local area networks, a data synchronization mechanism for forwarding the data needing to be synchronized through the equipment management unit is selected. Therefore, the data synchronization method has the capacity of realizing data synchronization among the intelligent devices through the local area network and the capacity of realizing data synchronization among the intelligent devices through the data forwarding of the device management unit, and can automatically select a proper mode to realize the data synchronization among the intelligent devices under the connection scenes of different intelligent devices.

An application scenario example of a data synchronization method is provided. Taking an intelligent home system comprising an intelligent device A, an intelligent device B, an intelligent device C, a router and a cloud server as an example, the intelligent device A, the intelligent device B and the intelligent device C are all connected to the cloud server. The data synchronization method is applied to the intelligent home system shown in fig. 1 e. Referring to fig. 1e, an intelligent device a and an intelligent device B are located in a local area network 1 constructed by a WIFI router 1; the intelligent device C is located in the local area network 2 constructed by the WIFI router 2; the WIFI router 1 and the WIFI router 2 are connected to the home router to access a network of a communication operator through the home router, and data transmission is carried out between the network and the cloud server.

In this scenario example, after the intelligent device a, the intelligent device B, and the intelligent device C are connected to the cloud server, the cloud server may generate a cloud device list including information of the intelligent device a, the intelligent device B, and the intelligent device C. The intelligent device A is used as a data synchronization device, the intelligent device A can send an acquisition request to a cloud server through the WIFI router 1 and the home router, and the cloud server sends a cloud device list to the intelligent device A after receiving the acquisition request sent by the intelligent device A. The intelligent device A can also broadcast inquiry information through the local area network 1, and after receiving the broadcast inquiry information, the intelligent device B in the local area network 1 can send reply information to the intelligent device A through the local area network 1. The intelligent device A receives the reply information sent by the intelligent device B and can generate a local area network device list according to the information of the intelligent device A and the intelligent device B. According to the comparison result between the cloud device list and the local area network device list, the intelligent device A can find that the cloud device list is different from the local area network device list, and the intelligent device A can select to synchronize data with the intelligent device B and/or the intelligent device C through the cloud server.

The present specification provides yet another application scenario example of the data synchronization method. The data synchronization method can also be applied to the intelligent home system shown in fig. 1 f. Referring to fig. 1f, an intelligent device a, an intelligent device B, and an intelligent device C are located in a local area network 1 constructed by a WIFI router 1; the WIFI router 1 is connected to the home router, so as to access a network of the communication operator through the home router, and perform data transmission with the cloud server through the network.

In this scenario example, with the intelligent device a as the data synchronization device, the intelligent device a may send an acquisition request to the cloud server through the WIFI router 1 and the home router, and after receiving the acquisition request sent by the intelligent device a, the cloud server sends a cloud device list including information of the intelligent device a, the intelligent device B, and the intelligent device C to the intelligent device a. The intelligent device A can also broadcast inquiry information through the local area network 1, and after the intelligent device B and the intelligent device C in the local area network 1 receive the broadcast inquiry information, reply information can be respectively sent to the intelligent device A through the local area network 1. The intelligent device A receives reply messages sent by the intelligent device B and the intelligent device C, and can generate a local area network device list according to the information of the intelligent device A, the intelligent device B and the intelligent device C. According to the comparison result between the cloud device list and the local area network device list, the intelligent device A can find that the cloud device list is the same as the local area network device list, and then the intelligent device A can select to perform data synchronization with the intelligent device B and/or the intelligent device C through the local area network 1.

In some embodiments, the cloud device list may be actively sent to the smart device by the cloud server. The comparison result between the cloud device list and the local area network device list may be obtained by comparing the device information in the cloud device list with the device information in the local area network device list.

In this scenario example, the intelligent device a, the intelligent device B, and the intelligent device C connected to the cloud server are devices that adopt the same private communication protocol (communication protocol defined by the producer), and the query information broadcast by the intelligent device a through the local area network 1 is information that satisfies the private communication protocol, which can only be acquired and resolved by the intelligent device B and the intelligent device C. Therefore, other intelligent devices possibly included in the local area network 1 cannot reply according to the query information broadcast by the intelligent device a, and the local area network device list acquired by the intelligent device a does not include information of other intelligent devices. Therefore, the comparison result between the cloud device list and the local area network device list may also be obtained by comparing the number of devices in the cloud device list with the number of devices in the local area network device list.

In the above scenario example, the data synchronization device may only focus on the smart device of the specified device type in the cloud device list and the local network device list. Illustratively, with continued reference to FIG. 1e, it is assumed that the device types of Smart device A and Smart device B are stereo and the device type of Smart device C is desk lamp. When the cloud device list is compared with the local area network device list, only the intelligent devices with the sound types can be focused on, so that the intelligent device A can compare information of the intelligent devices with the sound types in the cloud device list with information of the intelligent devices with the sound types in the local area network device list, or compare the number of the intelligent devices with the sound types in the cloud device list with the number of the intelligent devices with the sound types in the local area network device list, and accordingly data synchronization can be conducted between the intelligent device B and the intelligent device 1 through the local area network.

In some embodiments, the data synchronization device may send an acquisition request carrying a specified device type to the cloud server to request to acquire a cloud device list including information of intelligent devices only of the specified device type from the cloud server, and broadcast, through a local area network where the data synchronization device is located, query information carrying the specified device type to acquire a local area network device list including information of intelligent devices only of the specified device type in the local area network. For example, assuming that the device type of the smart device a is sound, the smart device a may send an acquisition request carrying the sound device type to the cloud server to request to acquire a cloud device list including information of smart devices only including the sound device type from the cloud server. Accordingly, the intelligent device a may broadcast query information carrying the type of the audio device through the local area network 1 to instruct the intelligent device of the type of the audio device in the local area network 1 to send reply information to the intelligent device a, so that the intelligent device a may generate a local area network device list only containing information of the intelligent device of the type of the audio device.

In the above scenario example, after the intelligent device a acquires the cloud device list, if the number of intelligent devices in the cloud device list reaches the preset device number threshold, the intelligent device a may determine that data synchronization with other intelligent devices is required, and acquire the local area network device list through the local area network 1. It can be understood that, when the number of intelligent devices of the specified device type in the cloud device list reaches the preset device number threshold, the intelligent device a may acquire the local network device list through the local network 1.

In some embodiments, the preset device number threshold may be 1 or 2.

It should be noted that, in the above scenario example, the intelligent device B or the intelligent device C obtains the cloud device list and the corresponding local area network device list, and determines a manner of performing data synchronization with other intelligent devices through the cloud server or the corresponding local area network, which is not described herein.

The present embodiment provides a data synchronization method applied to a data synchronization device, and referring to fig. 2a, the data synchronization device 200 is connected to a device management unit 202, and the data synchronization device 200 is located in a target local area network. Referring to fig. 2b, the data synchronization method may include the following steps.

S210, acquiring a first device list from a device management unit; the first device list includes information of intelligent devices connected to the device management unit.

Wherein the data synchronization device may be a source device that initiates data synchronization. The device management unit may be a cloud server, or may be a terminal or the like provided with a device management application, for managing the intelligent devices connected to the device management unit, forwarding data between the intelligent devices, and the like. The intelligent device may be a functional device with computing processing capability, or may be a router, gateway, or the like.

Specifically, the data synchronization device may request to the device management unit to acquire the first device list, and cause the device management unit to transmit the first device list to the data synchronization device. The data synchronization device may obtain information of the intelligent device connected to the device management unit according to the obtained first device list.

In some embodiments, the first device list may also be sent to the data synchronization device actively by the device management unit.

It is understood that the device management unit may generate a corresponding device list according to information of the intelligent devices connected to the device management unit, so as to facilitate device management, etc.

It should be noted that, interconnection and interworking can be performed between the intelligent devices connected to the same device management unit, so the intelligent devices obtained according to the first device list are intelligent devices capable of interconnection and interworking. If the device management unit is a cloud server, the information of the intelligent devices in the first device list is information of the intelligent devices under the same intelligent device management account (such as a smart home account, a smart office account, a smart mall account, a smart hospital account, etc.) connected to the cloud server in the same place (such as a home house, an office, a mall, a hospital, etc.); if the device management unit is a terminal installed with a device management application (for example, a smart home application, etc.), the information of the smart device in the first device list is the information of the smart device under the same device management application connected to the terminal in the same location.

S220, acquiring a second equipment list through the target local area network; the second device list comprises information of intelligent devices located in the target local area network.

Specifically, the data synchronization device may search for an intelligent device located in a target local area network through the target local area network where the data synchronization device is located by using a method of automatically discovering devices in the local area network, and obtain a corresponding second device list according to the searched information of the intelligent device and the information of the data synchronization device.

It should be noted that, the data synchronization device can perform interconnection and intercommunication between the intelligent device in the target local area network searched by the target local area network and the data synchronization device. Therefore, the intelligent devices obtained according to the second device list are intelligent devices capable of interconnection and interworking.

S230, according to a comparison result between the second device list and the first device list, performing data synchronization on at least part of the intelligent devices in the first device list through the device management unit, or performing data synchronization on at least part of the intelligent devices in the second device list through the target local area network.

In some cases, the location where the data synchronization device is located may have more than one local area network, and the target local area network has an interception function on data of other local area networks, so that all intelligent devices which can be interconnected and intercommunicated with the data synchronization device may not be searched for by the data synchronization device through the target local area network, and the second device list may not include information of the part of intelligent devices which are not searched for. It will be appreciated that the intelligent devices connected to the device management unit comprise intelligent devices located in the target local area network, and that the information of the intelligent devices in the first device list comprises information of the intelligent devices in the second device list. Thus, it is possible to determine whether or not the smart devices connected to the device management unit are all located in the target lan based on the comparison result between the second device list and the first device list. Thus, the data synchronization device may determine to perform data synchronization with the target smart device through the device management unit or the target local area network.

Specifically, after the data synchronization device acquires the first device list and the second device list, the second device list may be compared with the first device list. According to the comparison result between the second device list and the first device list, the data synchronization device can determine whether the intelligent device in the target local area network is consistent with the intelligent device connected to the device management unit. If the intelligent device in the target local area network is inconsistent with the intelligent device connected to the device management unit, the data synchronization device can judge that the intelligent device crossing the local area network exists. The data synchronization device may determine at least a portion of the intelligent devices that need to perform data synchronization according to the first device list, use the at least a portion of the intelligent devices as target intelligent devices, send data that need to be synchronized to the device management unit, and the device management unit forwards the data that need to be synchronized to the at least a portion of the intelligent devices to complete data synchronization between the data synchronization device and the target intelligent devices.

If the intelligent devices in the target local area network are judged to be consistent with the intelligent devices connected to the device management unit, the data synchronization device can judge that the intelligent devices are all located in the target local area network. The data synchronization device may determine at least a portion of the intelligent devices that need to perform data synchronization according to the second device list, use the at least a portion of the intelligent devices as target intelligent devices, and send data that needs to be synchronized to the at least a portion of the intelligent devices through the target local area network, so as to complete data synchronization between the data synchronization device and the target intelligent devices.

The data synchronization device may perform data synchronization with the target intelligent device, or may perform data sharing, data exchange, and the like with the target intelligent device.

In the above embodiment, the two data synchronization schemes are combined to provide a scheme capable of automatically selecting a data synchronization mechanism, aiming at the defect that the scheme for performing data synchronization only through the local area network in the related art is dependent on the network topology structure between intelligent devices and the defect that the scheme for performing data synchronization only through the device management unit in the related art has a large influence on the uplink network rate and the data synchronization efficiency. By establishing a set of rule switching logic, when the intelligent devices are all located in the same local area network, the data synchronization among the intelligent devices can be automatically selected through the local area network; when the intelligent devices are not located in the same local area network, the data forwarding is automatically selected through the device management unit so as to realize the data synchronization among the intelligent devices. Therefore, proper data synchronization modes can be selected under different scenes, dependence on network topology structures among intelligent devices is reduced to a certain extent, and influences on uplink network speed and data synchronization efficiency are reduced.

In some embodiments, according to the comparison result between the second device list and the first device list, performing, by the device management unit, data synchronization on at least a portion of the intelligent devices in the first device list may include: and if the comparison result shows that the second equipment list is different from the first equipment list, carrying out data synchronization on at least part of intelligent equipment in the first equipment list through the equipment management unit.

In some cases, since the formats of the first device list and the second device list may be formats agreed in advance between the data communication device and the device management unit, the second device list may be compared with the first device list to determine whether the second device list is identical to the first device list.

Specifically, the information of the intelligent device in the second device list may be compared with the information of the intelligent device in the first device list, and if the comparison finds that the first device list includes the information of the intelligent device that is not in the second device list, the comparison indicates that the second device list is different from the first device list. The data synchronization device may determine at least a portion of the intelligent devices that need to perform data synchronization according to the first device list, and send the data that need to be synchronized to the device management unit, where the device management unit forwards the data that needs to be synchronized to the at least a portion of the intelligent devices to complete data synchronization.

Illustratively, the intelligent device a, the intelligent device B and the intelligent device C are connected to the device management unit, and the intelligent device a is used as a data synchronization unit. The intelligent device A and the intelligent device B are located in the local area network 1 built by the router 1, and the intelligent device C is located in the local area network 2 built by the router 2. The intelligent device A acquires a first device list from the device management unit, and the first device list comprises information of the intelligent device A, information of the intelligent device B and information of the intelligent device C. The intelligent device a obtains the second device list through the local area network 1, and the intelligent device a can discover the intelligent device B through the local area network 1, so that the second device list includes information of the intelligent device a and information of the intelligent device B. Comparing the information of the intelligent device in the second device list with the information of the intelligent device in the first device list, and finding that the first device list contains the information of the intelligent device C which is not in the second device list, wherein the information of the intelligent device C is different from the information of the intelligent device C in the first device list. The intelligent device A sends the data to be synchronized to the device management unit, and the device management unit forwards the data to be sent to the intelligent device B and/or the intelligent device C in the first device list, so that the data synchronization of the intelligent device A and at least part of the intelligent devices in the first device list is completed.

In some embodiments, the device list may include information such as a device identifier, a device name, and the like of the smart device, where the device identifier is used to uniquely identify the corresponding smart device, and may be an SM code or a MAC address of the smart device, and the like.

Specifically, the data synchronization device may send query information through the target lan in a broadcast manner, so as to be used for searching for the intelligent device located in the target lan. And under the condition that the intelligent equipment in the target local area network receives the query information sent by the data synchronization equipment, the reply information containing the information of the intelligent equipment can be sent to the data synchronization equipment through the target local area network. And the data synchronization equipment receives the reply information sent by the intelligent equipment, and can obtain the information of the intelligent equipment according to the reply information. The data synchronization device may generate a second device list based on the information of the intelligent device and the information of the data synchronization device.

In some embodiments, the data synchronization device may broadcast query information over the target local area network based on the specified private communication protocol for searching for intelligent devices located in the target local area network that employ the specified private communication protocol. Accordingly, the intelligent device adopting the specified private communication protocol in the target local area network can receive the query information sent by the data synchronization device and send corresponding reply information to the data synchronization device through the target local area network.

For example, taking an intelligent home system as an example, the intelligent home system comprises an intelligent device A, an intelligent device B, an intelligent device C, an intelligent device D and an intelligent device E, which are all located in the same local area network.

And the intelligent device A is used as the data synchronization device, the intelligent device A broadcasts query information through the local area network, the intelligent device B and the intelligent device C can receive the query information and respectively send corresponding reply information to the intelligent device A through the local area network, and the intelligent device D and the intelligent device E can not receive the query information, so that the corresponding reply information can not be sent to the intelligent device A. Therefore, the intelligent device a can obtain the information of the intelligent device B and the intelligent device C according to the received reply information sent by the intelligent device B and the intelligent device C, and generate a corresponding second device list according to the information of the intelligent device a, the intelligent device B and the intelligent device C.

Further, the data synchronization device may filter in the second device list according to the specified device type under the condition that the second device list is obtained, and determine that the device type is information of the intelligent device of the specified device type. The data synchronization device may determine, according to a comparison result between information of the intelligent device of the specified device type in the second device list and information of the intelligent device of the specified device type in the first device list, to perform data synchronization on at least part of the intelligent devices in the first device list through the device management unit, or perform data synchronization on at least part of the intelligent devices in the second device list through the target local area network.

Wherein, intelligent device A is sound equipment, intelligent device B is air conditioning equipment, intelligent device C is sound equipment, intelligent device D is desk lamp equipment, and intelligent device E is area screen display equipment. And the intelligent device A is used as a data synchronization device, and can send a first device list acquisition request to the device management unit, so that the device management unit can send a first device list containing information of the intelligent device A, the intelligent device B, the intelligent device C, the intelligent device D and the intelligent device E to the intelligent device A. The intelligent device a can also broadcast query information through the local area network 1, and the intelligent device B and the intelligent device C in the local area network 1 send corresponding reply information to the intelligent device a according to the query information, so that the intelligent device a can generate a second device list according to the information of the intelligent device a, the intelligent device B and the intelligent device C. If the intelligent device a only needs to perform data synchronization with the intelligent device with the device type being the audio device, the intelligent device a may screen in the first device list and the second device list according to the designated device type being the audio device, determine information of the intelligent device with the device type being the audio device, that is, determine information of the intelligent device a and the intelligent device C in the first device list, and determine information of the intelligent device a and the intelligent device C in the second device list. The intelligent device a can determine that the intelligent devices needing to be synchronized are all located in the same local area network according to the comparison result between the screened second device list and the first device list, so that the intelligent device a can send the data needing to be synchronized to the intelligent device C through the local area network 1.

For example, if the intelligent device a only needs to perform data synchronization with the intelligent device with the device type being the on-screen display device, the intelligent device a may screen in the first device list according to the specified device type being the on-screen display device, and determine information of the intelligent device with the device type being the on-screen display device, that is, determine information of the intelligent device E in the first device list. The intelligent device A screens in the second device list according to the appointed device type as the on-screen display device, and as the second device list has no information of the intelligent device with the device type as the on-screen display device, an empty list can be obtained after the second device list is screened. The intelligent device a can determine that the intelligent devices needing to be synchronized are respectively located in different local area networks according to the comparison result between the screened second device list and the first device list, so that the intelligent device a can forward the data needing to be synchronized to the intelligent device E through the device management unit. The case where the intelligent device B, the intelligent device C, the intelligent device D, and the intelligent device E are respectively data synchronization devices will not be described in detail here.

In other embodiments, the data synchronization device may send a first device list acquisition request to the device management unit according to the specified device type to request that the first device list including information of the smart device of the specified device type be acquired from the device management unit. The data synchronization device may also broadcast query information through the target local area network according to the specified device type, so as to instruct the intelligent device of the specified device type in the target local area network to send reply information to the data synchronization device, so that the data synchronization device generates a second device list including information of the intelligent device of the specified device type.

Taking the smart home system as an example, taking the smart device a as the data synchronization device, if the smart device a only needs to perform data synchronization with the smart device with the device type being the audio device, the smart device a may send a first device list obtaining request to the device management unit according to the designated device type being the audio device, so that the device management unit sends a first device list including information of the smart device with the device type being the audio device to the smart device a, that is, sends a first device list including information of the smart device a and information of the smart device C to the smart device a. The intelligent device a may also broadcast query information through the local area network 1 to instruct the intelligent device with the device type being the acoustic device to send reply information to the intelligent device a, that is, instruct the intelligent device C to send reply information to the intelligent device a, so that the intelligent device a generates a second device list according to the information of the intelligent device a and the intelligent device C. According to the comparison result between the second device list and the first device list, the intelligent device A determines that the intelligent devices needing to be subjected to data synchronization are all located in the same local area network, so that the intelligent device A can send the data needing to be synchronized to the intelligent device C through the local area network 1.

For example, if the intelligent device a only needs to perform data synchronization with the intelligent device with the device type being the on-screen display device, the intelligent device a may send a first device list obtaining request to the device management unit according to the specified device type being the on-screen display device, so that the device management unit sends a first device list including information of the intelligent device with the device type being the on-screen display device to the intelligent device a, that is, sends a first device list including information of the intelligent device E to the intelligent device a. The intelligent device a may also broadcast query information over the local area network 1 to instruct the intelligent device, which is a display device with a screen, to send reply information to the intelligent device a. Since no device type in the local area network 1 is a smart device with a screen display device, the smart device a may generate an empty second device list. According to the comparison result between the second device list and the first device list, the intelligent device A determines that the intelligent devices needing to be subjected to data synchronization are located in different local area networks, so that the intelligent device A can forward the data needing to be synchronized to the intelligent device E through the device management unit. The case where the intelligent device B, the intelligent device C, the intelligent device D, and the intelligent device E are respectively data synchronization devices will not be described in detail here.

It should be noted that, the data synchronization device may broadcast the query information through the target lan in a manner of UDP broadcast or the like. The private communication protocol is a predefined private protocol for interconnection and interworking between intelligent devices, and can be a private protocol defined by a producer of the intelligent devices or other private protocols. Through the device management unit, the MQTT (Message Queuing Telemetry Transport, message queue telemetry transport protocol) protocol based on the publish/subscribe mode or the specified private communication protocol may be employed for data synchronization with at least part of the smart devices in the first list of devices.

In some embodiments, obtaining, by the target local area network, the second device list may include: and if the number of the intelligent devices of the first device list reaches a preset device number threshold, acquiring a second device list through the target local area network.

In some cases, if the data synchronization device finds that there is no intelligent device that needs to perform data synchronization according to the first device list acquired from the device management unit, the data synchronization device may not need to acquire the second device list through the target local area network. Therefore, before the data synchronization device acquires the second device list through the target local area network, the number of intelligent devices in the first device list can be judged.

Specifically, the data synchronization device may determine the number of intelligent devices of the first device list according to the first device list acquired from the device management unit. If the number of the intelligent devices of the first device list reaches a preset device number threshold value, indicating that intelligent devices needing to perform data synchronization exist in a place where the data synchronization device is located, the data synchronization device acquires a second device list through a target local area network; if the number of the intelligent devices of the first device list does not reach the preset device number threshold, the data synchronization device does not need to acquire a second device list through the target local area network if the intelligent devices needing to perform data synchronization do not exist in the place where the data synchronization device is located.

In some embodiments, the first device list includes information of all intelligent devices connected to the device management unit, the number of intelligent devices in the first device list is the number of all intelligent devices, and the preset device number threshold may be 2.
