[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0033] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0034] It should be noted that the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present disclosure are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects, and the descriptions of "first" and "second" do not limit the objects to be different.

[0035] Smart space is a work or learning space embedded with computing, information equipment and various types of sensor devices. Its purpose is to enable users to easily access various smart applications in the smart space, so that they can work efficiently alone or with others. For example, smart space can be a smart home, smart classroom, smart conference room, etc.

[0036] In the related art, when the device information or the interaction information between devices in the smart space changes, the central server needs to calculate and update the ontology knowledge base in time. All the calculation work is completed by the central server, which requires a large number of calculation tasks, which is prone to overload and cause performance problems. In addition, the device information and the interaction information between devices are usually stored in the central server, which has the risk of node failure. Therefore, the present disclosure proposes a smart device management solution based on distributed storage in the smart space, which automatically triggers the execution of the smart device management program in the distributed storage system, realizes the automatic update of the ontology knowledge base, and realizes the access and information storage of smart devices in the smart space.

[0037] Figure 1 A schematic diagram of the system architecture of a device management method or apparatus based on distributed storage in a smart space to which the present disclosure can be applied is shown.

[0038] like Figure 1 As shown, the system architecture may include smart device 101 , smart device 102 , smart device 103 , smart device 104 , smart device 105 , and smart device 106 .

[0039] Among them, smart device 101, smart device 102, smart device 103 and smart device 104 are smart devices that have joined the smart space, and smart device 105 and smart device 106 are smart devices that have not joined the smart space.

[0040] Figure 1 In the embodiment, smart device 101, smart device 102, smart device 103 and smart device 104 can provide storage resources for the distributed storage system, that is, smart device 101, smart device 102, smart device 103 and smart device 104 are storage nodes of the distributed storage system. The distributed storage system can store device-related information of each smart device that has been added to the smart space, and then the smart devices in the smart space can be managed based on the distributed storage technology.

[0041] Among them, the distributed storage can be distributed storage based on blockchain technology. Blockchain technology is a new type of decentralized information technology. Blockchain, in essence, is a shared database. In the blockchain system, every once in a while, the transaction data generated by each participating entity will be packaged into a data block. The data blocks are arranged in chronological order to form a chain of data blocks. Each participating entity has the same data chain and cannot be tampered with unilaterally. Any modification of information can only be carried out with the consent of the agreed proportion of entities, and only new information can be added, and old information cannot be deleted or modified, thereby realizing information sharing and consistent decision-making among multiple entities, ensuring that the identities of each entity and the transaction information between entities cannot be tampered with, and are open and transparent.

[0042] In the disclosed embodiment, if the distributed storage is distributed storage based on blockchain, smart device 101, smart device 102, smart device 103 and smart device 104 can be deployed as blockchain nodes to form a blockchain network, so that the smart devices in the smart space can be managed based on blockchain technology.

[0043] It should be noted that any smart device in the system architecture is any device, instrument or machine with computing and processing capabilities, including but not limited to smart appliances, smart home devices, smart wearable devices, smart conference room devices and smart medical devices.

[0044] It should be understood that Figure 1 The number of smart devices in the figure is only for illustration, and any number of smart devices may be provided according to implementation requirements.

[0045] The device management method based on distributed storage in the smart space of the embodiment of the present disclosure is described in detail below in conjunction with specific embodiments.

[0046] Figure 2 A flow chart of a device management method based on distributed storage in a smart space according to an embodiment of the present disclosure is shown. Figure 2 The method provided in the embodiment can be executed by any electronic device, and the present disclosure does not limit this. Figure 2 As shown, the device management method based on distributed storage in a smart space may include the following steps.

[0047] Step S210: If the space state of the smart space changes, the smart device management program in the distributed storage system is triggered to execute and update the interaction information of each first smart device.

[0048] The smart space includes a central server and a first smart device. The central server may be a central server of the smart space or a centralized server of the smart space, and the central server may be called a space brain; the first smart device refers to a device that has been added to the smart space, such as a smart appliance, a smart wearable device, etc.

[0049] In the embodiment of the present disclosure, at least some of the multiple first smart devices provide storage resources for the distributed storage system. That is, if a smart device is added to the smart space, the smart device may be a storage node of the distributed storage system or may not be a storage node of the distributed storage system. If a smart device added to the smart space does not provide storage resources for the distributed storage system, the smart device may send a request to the distributed storage system, such as sending an information update request when the space state of the smart space changes, so as to update the interaction information of the smart device through the request.

[0050] In the disclosed embodiment, the distributed storage is a distributed storage based on blockchain, so the first smart device can be deployed as a blockchain node in the blockchain network, that is, the first smart device is networked to obtain a blockchain network, so that the smart device can be managed based on blockchain technology. Furthermore, the computing power information of the first smart device can be used to deploy the first smart device with insufficient computing power as a light node, and the first smart device with sufficient computing power as a full node. The computing power information may include information related to the computing performance of the device, such as the computing and storage of the smart device.

[0051] The smart device management program is a program used to manage smart devices in a distributed storage system. In some embodiments of the present disclosure, the smart device management program includes a device identification field, a device status information field, and a device interaction information field.

[0052] The fields of the smart device manager are as follows:

[0053] Device identification: robotID is the unique identification assigned to the smart device after it enters the smart space;

[0054] Device status information: robotStatus, used to describe the status of the smart device, including but not limited to power on, power off, working, waiting to work, scheduled working, etc. In addition, the device status information may also include the location information of the device;

[0055] Device interaction information: associatedInfo, used to describe the correlation between a smart device and other smart devices in a smart space. For example, the correlation between a smart door and a sweeping robot in a smart home. When the smart door is closed, the activity area of ​​the sweeping robot is restricted.

[0056] Furthermore, the smart device management program also includes at least one of the following fields: a device name field, a device function information field, and an update interaction information field.

[0057] Among them, the device name: robotName, refers to the specific name of the smart device, such as a sweeping robot, smart air conditioner, etc.; the device function information: robotFunc, is used to describe the specific usage function of the smart device; update interaction relationship: updateInfo(), which is a method for updating interaction information. This method is used to update the interaction information between the smart device and other smart devices in the smart space.

[0058] In the disclosed embodiment, the smart device management program can be a smart device management contract in the blockchain network, that is, a smart contract on the blockchain that can be triggered by transactions. A smart contract is a computer protocol designed to disseminate, verify or execute contracts in an information-based manner. A blockchain smart contract is a piece of code written on the blockchain. Once an event triggers a clause in the contract, the code is automatically executed. In other words, it is executed when the conditions are met, without the need for human control. In the disclosed embodiment, the management of smart devices is achieved by automatically triggering the designed smart device management contract.

[0059] Figure 3 A schematic diagram of the structure of a smart device management program according to an embodiment of the present disclosure is shown. Figure 3 In an embodiment, the intelligent device management program may include a device identification field (string robotID), a device name field (string robotName), a device function information field (string robotFunc), a device status information field (string robotStatus), a device interaction information field (string assciatedInfo), and a method for updating interaction information (function updateInfo()).

[0060] It should be noted that Figure 3 The embodiment is an example of an intelligent device management program. The intelligent device management program can be set according to actual needs, for example, it can only include a device identification field, a device interaction information field, and a method for updating interaction information. Of course, in addition to including a device identification field, a device name field, a device function information field, a device status information field, a device interaction information field, and a method for updating interaction information, the intelligent device management program can also include other fields, such as a device location information field, a device usage time field, a device usage user authority field, etc., which can be set according to actual needs, and the embodiments of the present disclosure do not limit this.

[0061] In the disclosed embodiment, the structure of the intelligent device management program can be set according to actual needs. When the conditions are met, the intelligent device management program is triggered for execution without the need for human control. This enables management of intelligent devices based on the intelligent device management program, improves the efficiency of updating the status information of the intelligent space, reduces the cost of manual intervention, and realizes automatic updating of the ontology knowledge base.

[0062] In some embodiments of the present disclosure, if the spatial state of the smart space changes in step S210, the smart device management program in the distributed storage system is triggered to execute, the interaction information of each first smart device is updated, and the updated interaction information of each first smart device is obtained. It can include: if the spatial state of the smart space changes, the state change information is obtained; the state change information is uploaded to the distributed storage system, the smart device management program is triggered to perform calculations, the updated interaction information of each first smart device is obtained, and the updated interaction information of each first smart device is stored.

[0063] In the embodiment of the present disclosure, after a smart device joins a smart space, the device-related information of the smart device can be stored in a distributed storage system. The device-related information of the smart device may include one or more of the following options: device identification, device name, function information, status information, and interaction information. Of course, in addition to this information, other information such as device appearance may also be included.

[0064] In the embodiment of the present disclosure, the smart device management program may include interaction information and a method for updating the interaction information. When the space state of the smart space changes, the state change information of the space may be obtained, and the change state information may be uploaded to the distributed storage system, triggering the execution of the smart device management program in the distributed storage system, calling the method for updating the interaction information in the program, updating the interaction information of each first smart device, and then obtaining the updated interaction information of each first smart device.

[0065] As mentioned above, there are multiple first smart devices. Therefore, in this step, when the spatial state of the smart space changes, the smart device management program can be triggered to update the interaction information of each first smart device, that is, to update the correlation between the first smart device and other smart devices in the smart space, and obtain the updated interaction information of the first smart device.

[0066] by Figure 1 For example, the smart device management program can be triggered to update the correlation between the smart device 101 and other smart devices 102, 103, and 104 in the smart space, and obtain updated interaction information of the smart device 101. Similarly, the correlation between the smart device 102 and other smart devices 101, 103, and 104 in the smart space is updated to obtain updated interaction information of the smart device 102; the correlation between the smart device 103 and other smart devices 101, 102, and 104 in the smart space is updated to obtain updated interaction information of the smart device 103; the correlation between the smart device 104 and other smart devices 101, 102, and 103 in the smart space is updated to obtain updated interaction information of the smart device 104.

[0067] In some embodiments of the present disclosure, the change in the space state of the smart space may include a second smart device joining the smart space, and / or a state change of a target smart device.

[0068] The second smart device refers to a smart device that requests to join the smart space, for example Figure 1 If the second smart device is added to the smart space, the space state of the smart space will change. For example, the smart devices added to the smart home include a smart door and a sweeping robot. When a human detector is added to the smart home, the space state of the smart home will change. For example, if the human detector detects that a person has gone out, the smart door can be automatically closed. If the human detector detects that a person has gone out, the sweeping robot starts cleaning.

[0069] And, the target smart device is a smart device that has been added to the smart space. That is, if the state of the smart device that has been added to the smart space changes, the space state of the smart space will change. The smart space includes multiple first smart devices, and the target smart device is a smart device among the multiple first smart devices.

[0070] In some embodiments of the present disclosure, the change in the space state of the smart space is the addition of the second smart device to the smart space. The device management method based on distributed storage in the smart space may also include access and information storage management of the second smart device. Figure 4 FIG. 4 shows a flow chart of access to a second smart device and information storage management according to an embodiment of the present disclosure. Figure 4 As shown, the access and information storage management of smart devices may include the following steps.

[0071] Step S410: receiving a request for joining a smart space sent by a second smart device, and authenticating the second smart device according to the request.

[0072] The smart space may include an authentication module, through which a request to join the smart space sent by the second smart device is received, and after receiving the joining request, the second smart device is authenticated. Specifically, the authentication module may confirm whether the function information, computing power information or other information of the device reported by the second smart device is consistent with the actual situation of the second smart device, and if so, the authentication is passed.

[0073] Step S420, after the authentication is passed, trigger the execution of the smart device management program to upload the device related information of the second smart device to the distributed storage system for storage.

[0074] Among them, the device-related information of the second smart device includes data attributes and interaction attributes. Data attributes can be understood as information related to the device attributes of the second smart device, which may include the device identification of the second smart device and the functional information of the second smart device; interaction attributes can be understood as the correlation information between the second smart device and other smart devices in the smart space, which may include the interaction information of the second smart device. Furthermore, the device identification of the second smart device is assigned to the second smart device by the smart space after authentication, and the interaction information of the second smart device includes the correlation between the second smart device and each first smart device.

[0075] It should be noted that the data attributes of the second smart device may include not only the device identification of the second smart device and the functional information of the second smart device, but also other information related to the device attributes, such as the device name of the second smart device and the status information of the second smart device. The embodiments of the present disclosure are not limited to this.

[0076] After the authentication is passed, the second smart device can be confirmed to be added to the smart space, and relevant information of the second smart device, such as name, function, status and description of interaction relationship, can be obtained. The smart space can also assign a unique device identifier to the second smart device.

[0077] After confirming that the second smart device is added to the smart space, the smart device management program can be triggered to calculate the correlation between the second smart device and the first smart device in the smart space according to the description of the interaction relationship of the second smart device, and obtain the interaction information of the second smart device. In addition, based on the smart device management program, an information storage request is initiated to upload the device-related information of the second smart device to the distributed storage system for storage.

[0078] In the disclosed embodiment, if the distributed storage is a distributed storage based on blockchain, after confirming that the second smart device is added to the smart space, the smart device management contract on the blockchain network can be triggered, and the correlation between the second smart device and the first smart device in the smart space is calculated according to the description of the interaction relationship of the second smart device, and the interaction information of the second smart device is obtained. In addition, based on the smart device management contract, a request for information on-chain storage is initiated, and then after reaching a consensus on the blockchain network, the device-related information of the second smart device is uploaded to the blockchain for storage.

[0079] In the embodiment of the present disclosure, after the second smart device is authenticated, the second smart device is added to the smart space, and the device-related information of the second smart device is stored in a distributed storage system based on the smart device management program, thereby realizing the access and information storage of smart devices in the smart space, and storing the device-related information in the distributed storage system can avoid the risk of node failure when storing information in the central server.

[0080] In the disclosed embodiment, if the distributed storage is a distributed storage based on blockchain, after the second smart device is authenticated and confirmed to be added to the smart space, the second smart device can be deployed as a blockchain node in the blockchain network.

[0081] Furthermore, after the authentication is passed, the computing power information of the second smart device is obtained; if the computing power information of the second smart device does not meet the preset computing power requirements, it is confirmed that the second smart device will be deployed as a light node in the blockchain network; if the computing power information of the second smart device meets the preset computing power requirements, it is confirmed that the second smart device will be deployed as a full node in the blockchain network.

[0082] After the second smart device is authenticated, the computing power information of the second smart device can be obtained, including but not limited to the computing power and storage capacity of the second smart device, to determine whether the computing power information of the second smart device meets the preset computing power requirements. If the preset computing power requirements are not met, the second smart device is deployed as a light node in the blockchain network, so that the second smart device can query / store data, can interact with the blockchain, does not save the existing data on the blockchain, and does not participate in the consensus. If the preset computing power requirements are met, the second smart device is deployed as a full node in the blockchain network, so that the second smart device can save the data on the blockchain, can participate in the blockchain consensus, can interact with the blockchain, and can query / store data.

[0083] In the disclosed embodiment, if the distributed storage is a distributed storage based on blockchain, after the second smart device is authenticated and added to the smart space, the second smart device can be deployed as a blockchain node in the blockchain network, so that the blockchain network can be used to establish a connection between smart devices, so that the second smart device can quickly adapt to the smart space environment and establish a connection with the first smart device in the smart space. In addition, the second smart device can be deployed as a light node or a full node according to its computing power information, taking into account the computing power information of the second smart device, avoiding the problem of excessive load on the second smart device, thereby improving the overall efficiency and stability of the smart space.

[0084] In some embodiments of the present disclosure, a change in the spatial state of a smart space is caused by a second smart device joining the smart space, which triggers the execution of a smart device management program, and each first smart device determines the correlation between the first smart device and the second smart device, and updates the interaction information of the first smart device based on the determined correlation.

[0085] After the second smart device joins the smart space, the smart device management program may be triggered to execute, and each first smart device in the smart space may calculate the correlation between itself and the second smart device, and update its corresponding interaction information using the calculated correlation.

[0086] For example, the smart devices added to the smart home include smart doors and sweeping robots. When the human body detector is added to the smart home, the smart door will calculate the correlation with the human body detector and use the calculated correlation to update the interaction information of the smart door. The sweeping robot will calculate the correlation with the human body detector and use the calculated correlation to update the interaction information of the sweeping robot.

[0087] In some embodiments of the present disclosure, a change in the spatial state of the smart space is a state change of the target smart device, which triggers the execution of the smart device management program, and each first smart device updates the interaction information of the first smart device according to the state change information of the target smart device.

[0088] After the state of the target smart device changes, each first smart device in the smart space may update its corresponding interaction information according to the impact of the state change information of the target smart device on itself.

[0089] The smart space includes multiple first smart devices, and the target smart device is a smart device among the multiple first smart devices. In this case, each first smart device except the target smart device can update its corresponding interaction information according to the impact of the state change information of the target smart device on itself; and the target smart device can update the interaction information between the target smart device and other smart devices in the smart space.

[0090] For example, the smart devices added to a smart home include a smart door, a sweeping robot and a human detector. When the smart door changes from open to closed (which can be considered as a change in the position of the smart door), it will affect the activity area of ​​the sweeping robot and the detection range of the human detector. Therefore, the sweeping robot updates the interaction information, the human detector updates the interaction information, and the smart door can update its corresponding interaction information.

[0091] Furthermore, the state change of the target smart device includes at least one of a change in the position of the target smart device, a change in the working state of the target smart device, and the target smart device exiting the smart space.

[0092] The change in the location of the target smart device refers to the change in the location of the target smart device in the smart space. For example, the sweeping robot in a smart home moves from the kitchen to the living room.

[0093] The working state of the target smart device changes, which means that the working state of the target smart device changes, for example, the sweeping robot in a smart home changes from waiting to work to working.

[0094] The target smart device exits the smart space, which means that the target smart device exits, for example, the target smart device exits the smart home due to a malfunction of the sweeping robot.

[0095] Of course, the state change of the smart device may include other state changes in addition to changes in working state, changes in location, and exit from the smart space, which is not limited in the embodiments of the present disclosure.

[0096] In the disclosed embodiment, when the spatial state of the smart space changes, the smart device management program is triggered, and each smart device in the smart space updates its corresponding interaction information, thereby avoiding the need for all computing work to be completed by the central server when the spatial state of the smart space changes. This can reduce the load on the central server and improve the overall efficiency of the smart space.

[0097] Step S220: updating the ontology knowledge base of the smart space according to the updated interaction information of each first smart device.

[0098] Among them, the ontology knowledge base can provide a unified semantic description framework, so that the data between different smart devices can be described and represented in a consistent format, thereby achieving better data interaction and sharing. Smart space can use the ontology knowledge base to provide decisions for the linkage of smart devices in the space and the task execution of smart devices, thereby improving user experience and convenience.

[0099] In this step, each first smart device may transmit its corresponding updated interaction information to the central server, and then the central server processes and integrates the overall state change information in the smart space to update the ontology knowledge base of the smart space.

[0100] In some embodiments of the present disclosure, updating the ontology knowledge base of the smart space according to the updated interaction information of each first smart device in step S220 may include: transmitting the updated interaction information of each first smart device to the central server so that the central server updates the ontology knowledge base.

[0101] When each first smart device completes the update operation and reaches a consensus across the entire network, the updated information in the distributed storage system can be obtained and transmitted to the central server. The central server can then perform analysis and calculation based on the updated information to update the ontology knowledge base of the smart space.

[0102] In the embodiment of the present disclosure, when the spatial state of the smart space changes, the state change information is uploaded to the distributed storage system, triggering the execution of the smart device management program, each first smart device updates its corresponding interaction information, and transmits the updated interaction association information of each first smart device to the central server, so that the central server updates the ontology knowledge base of the smart space. In this way, the ontology knowledge base is updated by edge computing. Among them, the edge computing method is a method of generating calculations near the device end, and in the embodiment of the present disclosure, it refers to the method of updating interaction information of smart devices in the smart space.

[0103] Figure 5 FIG. 1 is a schematic diagram showing an embodiment of the present disclosure using edge computing to update the ontology knowledge base. Figure 5 As shown in the figure, when the spatial state change of the smart space is perceived, the update of the ontology knowledge base begins, triggering the smart device management program in the distributed storage system. Each smart device in the smart space calculates the impact of the state change on it and obtains its own updated interaction information. After all the smart devices in the smart space complete the update operation, they reach a consensus and transmit the updated information in the distributed storage system to the space brain, that is, the central server. The space brain performs analysis and calculation based on the updated information to complete the update of the ontology knowledge base.

[0104] In the embodiment of the present disclosure, edge computing is used to update the ontology knowledge base, fully utilize the computing power information of smart devices, and share computing tasks through smart devices, so as to improve the overall efficiency of the space system.

[0105] Figure 6 A flowchart of a device management method based on distributed storage in a smart space according to yet another embodiment of the present disclosure is shown. Figure 6 The embodiment shows the process of updating the ontology knowledge base when the spatial state of the smart space changes. Figure 6 As shown, the following steps may be included.

[0106] Step S601, when a new smart device is added, the new smart device is authenticated, and after the authentication is passed, the smart device management program is called to store the device-related information of the new smart device in the distributed storage system.

[0107] The device related information may include device identification, device name, function information, status information and interaction information. The smart device management program may include a device identification field, a device name field, a device function information field, a device status information field, a device interaction information field and a method for updating interaction information.

[0108] Step S602: a state change occurs in a smart device that has joined the smart space.

[0109] For example, the working status of a smart device that has joined the smart space changes, moves, or exits the smart space.

[0110] If a new smart device joins the smart space, or a smart device that has joined the smart space changes its state, it can be confirmed that the space state of the smart space has changed. It should be noted that in addition to the new smart device joining the smart space and the smart device that has joined the smart space changing its state, the space state change of the smart space may also include other situations, which are not limited in the embodiments of the present disclosure.

[0111] Step S603, triggering the smart device management program to update the "interaction information" field of each smart device in the smart space, that is, the interaction information between the smart device and other smart devices in the smart space.

[0112] When a new smart device is added, each smart device in the smart space calculates its relevance with the new smart device and updates the "interaction information" field.

[0113] When a state change occurs in a smart device that has joined the smart space, each smart device in the smart space calculates the impact of the state change on itself and updates the "interaction information" field.

[0114] Step S604: Transmit updated interaction information of each smart device to the central server.

[0115] Step S605: the central server processes the updated interactive information, integrates and calculates the overall state change information in the intelligent space, and updates the ontology knowledge base.

[0116] The following specific embodiments are listed to illustrate the device management method based on distributed storage in the smart space provided in the embodiments of the present disclosure. Specifically, taking the distributed storage as a distributed storage based on blockchain as an example, and taking the smart device management program as a smart device management contract as an example, the smart devices that have been added to the smart space can be deployed as blockchain nodes to form a blockchain network.

[0117] Figure 7 A schematic diagram showing the updating process of the ontology knowledge base of the smart space according to an embodiment of the present disclosure is shown. Figure 7 The embodiment illustrates the updating process of the ontology knowledge base of the smart space when a new smart device is added to the smart space. Figure 7 As shown, the following steps may be specifically included.

[0118] Step S701: A new smart device requests to join a smart space.

[0119] Step S702: The authentication module of the smart space authenticates the new smart device, and the new smart device can be added to the smart space after passing the authentication.

[0120] Step S703: the smart space assigns a unique identifier to the new smart device, and obtains the name, function, status, and interaction information of the new smart device with other devices in the smart space.

[0121] It should be noted that the interaction information with other devices in the smart space is a description of the correlation.

[0122] Step S704, triggering the call of the smart device management contract to store the device-related information of the new smart device on the blockchain.

[0123] The device-related information may include device identification, device name, function information, status information, and interaction information. The smart device management contract may include a device identification field, a device name field, a device function information field, a device status information field, a device interaction information field, and a method for updating interaction information. After the smart device management contract is triggered, the interaction information in step S703 may be converted into formatted data in accordance with the format agreed upon in the contract, so that it can be easily stored.

[0124] Step S705: Other smart devices that have joined the smart space sense that the space state has changed and a new smart device has joined.

[0125] In step S706, other joined smart devices use edge computing to calculate the impact of the state change on them respectively, and obtain their corresponding updated interaction information.

[0126] In step S707, other joined smart devices store their corresponding updated interaction information on the blockchain to update the information on the blockchain.

[0127] Step S708: All joined smart devices complete the update operation, and the blockchain reaches a consensus across the entire network, and the updated information on the blockchain is transmitted to the central server.

[0128] Step S709: the central server performs analysis and calculation based on the updated information to complete the update of the ontology knowledge base.

[0129] The device management method based on distributed storage in the smart space provided by the embodiment of the present disclosure, the smart space includes multiple first smart devices, at least some of the multiple first smart devices provide storage resources for the distributed storage system, and when the spatial state of the smart space changes, the smart device management program in the distributed storage system can be triggered, and the execution program updates the interaction information of each first smart device, and then updates the ontology knowledge base of the smart space according to the updated interaction information. In this way, when the spatial state of the smart space changes, the execution of the smart device management program is automatically triggered to update the interaction information of each first smart device, thereby realizing the automatic update of the ontology knowledge base, avoiding that all computing work is completed by the central server of the smart space, reducing the load of the central server, and improving the overall efficiency of the smart space. And, if the distributed storage is distributed storage based on blockchain, the management of smart devices in the smart space is realized based on blockchain technology. Due to the tamper-proof characteristics of blockchain, the security and reliability of the smart space system are guaranteed.
