[0051] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0052] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0053] The main solution of the embodiment of the present application is: obtaining a smart building contract based on the blockchain, and determining the building node information of the smart building based on the smart building contract; obtaining device data generated by smart devices from the edge gateway node of the smart building based on the building node information; performing risk assessment on the device data through a preset risk model to determine whether there is risk data in the device data; when risk data exists, performing risk repair on the target edge gateway node and target smart device corresponding to the risk data; updating the building node information based on the target edge gateway node and target smart device after risk repair, and reconstructing the smart building contract according to the updated building node information.

[0054] Current technologies use BIM models for smart building contract management. However, the construction and management of BIM models require specialized skills and knowledge, placing high demands on personnel. Furthermore, the establishment and maintenance of BIM models require significant time and financial investment. Furthermore, the use and management of smart building contracts collects and processes large amounts of user data, posing a pressing challenge in protecting user privacy.

[0055] This application provides a solution for managing and executing smart building contracts based on blockchain technology, improving data security and immutability during the management process. Furthermore, blockchain technology enables automated execution of smart contracts, reducing manual intervention during implementation and lowering labor costs during contract management.

[0056] It should be noted that the execution entity of this embodiment can be a computing service device with data processing, network communication, and program execution capabilities, such as a server or smart building server, or an electronic device or virtual device capable of implementing the aforementioned functions. This embodiment and the following embodiments will be described below using a smart building contract management device (hereinafter referred to as the management device) as an example.

[0057] Based on this, the embodiment of the present application provides a smart building contract management method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the smart building contract management method of this application.

[0058] In this embodiment, the smart building contract management method includes steps S10 to S40:

[0059] Step S10: obtaining a smart building contract based on the blockchain, and determining building node information of the smart building based on the smart building contract;

[0060] It is understandable that blockchain is a distributed database technology that uses cryptography to ensure the immutability and non-forgeability of data through a series of data blocks arranged in chronological order.

[0061] It should be understood that building node information is also the node information of the terminal nodes involved in the use of smart buildings. When obtaining the building node information, the management device can establish a connection with the terminal node, and then determine the type, quantity, location, performance and other information of the edge gateway nodes included in the smart building.

[0062] In one implementation of the embodiment of the present application, the building node information includes at least: call function information and edge gateway node information; the step of obtaining the smart building contract based on the blockchain and determining the building node information of the smart building based on the smart building contract includes:

[0063] Obtaining a blockchain contract address, and obtaining a smart building contract in the blockchain based on the blockchain contract address;

[0064] Parsing based on the smart building contract to determine the calling function information of the building node;

[0065] The edge gateway node information in the intelligent building is determined based on the calling function information.

[0066] It should be noted that the blockchain contract address is the location where the smart building contract is stored on the blockchain. Based on this blockchain contract address, the smart building contract can be retrieved. By parsing the smart building contract, the call function information of the building node corresponding to the smart building can be determined. Based on this call function information, the building node can be called to determine the edge gateway node information included in the smart building.

[0067] Step S20, acquiring device data generated by smart devices from the edge gateway node of the smart building based on the building node information;

[0068] Step S30: performing risk assessment on the device data using a preset risk model to determine whether risk data exists in the device data.

[0069] It is understandable that each edge gateway node can be connected to multiple smart devices and obtain device data of these smart devices.

[0070] It should be understood that when the management device determines the building node information, it can determine the edge node type, data, location, performance and other information in the smart building, and then obtain the device data generated by each smart device in the smart building based on these edge gateway nodes.

[0071] It should be noted that the aforementioned pre-defined risk model is a neural network model that evaluates input device data to determine whether the data contains risk data related to the protection of faulty devices. By determining whether the risk data exists, it is determined whether there are risky faulty devices in the smart building and the type of faulty device risk associated with the risk data.

[0072] Step S40: When risk data exists, performing risk repair on the target edge gateway node and target smart device corresponding to the risk data;

[0073] It can be understood that the above-mentioned target smart device is also the smart device that generates the risk data, and the above-mentioned target edge gateway node is also the gateway node corresponding to the risk data.

[0074] It should be noted that when risk data exists, the management device can determine risk repair information based on the device type of the target smart device, the risk type of the risk data, and the smart building contract, and then perform risk repair based on the risk repair information.

[0075] It is understood that the risk remediation information may include information about the responsible party for risk remediation, information about the cost of risk remediation, and information about the time of risk remediation. Based on the risk remediation information, the responsible party for risk remediation may be contacted to perform risk remediation, and corresponding risk remediation cost information may be output upon completion of risk remediation.

[0076] Step S50: updating the building node information based on the target edge gateway node and the target smart device after risk repair, and reconstructing the smart building contract according to the updated building node information.

[0077] It can be understood that when the risk repair is completed, the building node information can be updated based on the information of the target edge gateway node and the target smart device, thereby updating the corresponding building node information in the smart building contract and obtaining the reconstructed smart building contract.

[0078] The embodiment of the present application obtains a smart building contract based on a blockchain, and determines the building node information of the smart building based on the smart building contract; obtains device data generated by smart devices from the edge gateway node of the smart building based on the building node information; performs a risk assessment on the device data using a preset risk model to determine whether there is risk data in the device data; when risk data exists, performs risk repair on the target edge gateway node and target smart device corresponding to the risk data; updates the building node information based on the target edge gateway node and target smart device after risk repair, and reconstructs the smart building contract based on the updated building node information. Since the smart building contract acquisition and management is based on the blockchain, the security of the data is improved; by determining the risk data and the corresponding target edge gateway node and target smart device in the device data, the target smart device that fails in the smart building can be handled in a timely manner, thereby improving the reliability of the smart building.

[0079] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 2 The step of obtaining device data generated by smart devices from the edge gateway node of the smart building based on the building node information includes:

[0080] Step S21, determining the edge gateway node type and edge gateway node location to be collected in the intelligent building based on the building node information;

[0081] Step S22, determining a device data collection method based on the edge gateway node type;

[0082] It is understandable that the type of edge gateway node and the location of the edge gateway node in the smart building can be determined based on the building node information.

[0083] It should be noted that different types of edge gateway nodes may have different data processing capabilities and support different communication protocols. For basic edge gateway nodes, the corresponding device data collection method may be scheduled collection; for high-performance edge gateway nodes, the corresponding device data collection method may be real-time collection. Therefore, based on the edge gateway node's collection method, the management device's device data collection method from the edge gateway node can be determined; and based on the communication protocols supported by the edge gateway node, the communication method between the edge gateway node and the management device can be determined.

[0084] It should be noted that the type of edge gateway node can be selected based on the type of connected smart device. For smart devices with high real-time requirements, such as security equipment, lighting systems, and smart appliances, the edge gateway node they connect to can be a high-performance edge gateway node. For smart devices with less real-time requirements, such as sensor-type devices, the edge gateway node they connect to can be a basic edge gateway node.

[0085] Step S23: collecting device data stored by the edge gateway node at the edge gateway node location according to the collection method.

[0086] It is understandable that when determining the method for collecting device data, the device data stored by the edge gateway node at the edge gateway node location can be collected.

[0087] In one implementation of the embodiment of the present application, in order to detect risk data, the preset risk model can be as follows: Figure 3 As shown, the preset risk model includes: an input layer, a hidden layer, and an output layer; the step of performing risk assessment on the device data using the preset risk model to determine whether there is risk data in the device data includes:

[0088] Performing data preprocessing on the device data through the input layer to obtain model input data;

[0089] Performing neuron processing on the model input data through the hidden layer to determine a processing result;

[0090] The processing result is subjected to risk assessment through the output layer to determine whether there is risk data in the device data.

[0091] It should be noted that different smart device types can correspond to different preset risk models, and each preset risk model can correspond to multiple dimensions of device data. For example, for a preset risk device corresponding to a smart air conditioner, the input device data can include data on temperature changes, humidity changes, and other dimensions. By preprocessing the device data in multiple dimensions, the model input data can be obtained.

[0092] It should be explained that the number of hidden layers in the embodiment of the present application can be multiple ( Figure 3 For each hidden layer, there may be several neurons ( Figure 3 Five of these are shown in the figure. Each neuron receives model input data in various dimensions and performs weighted and nonlinear transformations based on the model input data, thereby mapping the neuron's input to the neurons in the next hidden layer. The neuron's processing results are obtained through the hidden layer's step-by-step mapping. The output layer then performs error processing on these results, thereby implementing a risk assessment of the input device data, determining whether the input device data is risky and the corresponding risk type.

[0093] This embodiment of the present application determines the type and location of edge gateway nodes to be collected in a smart building based on building node information; determines the device data collection method based on the edge gateway node type; and collects the device data stored by the edge gateway node at the edge gateway node location according to the collection method. Because the location of the edge gateway node and the device data collection method are determined based on building node information, the device data stored by the edge node is obtained, providing a data foundation for the management and execution of smart contracts.

[0094] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the first embodiment and / or the second embodiment can be referred to the above introduction and will not be described in detail later. Figure 4 , when risk data exists, the step of performing risk repair on the edge gateway node and target smart device corresponding to the risk data includes:

[0095] Step S41: When risk data exists, determining a target edge gateway node and a target smart device corresponding to the risk data;

[0096] Step S42: Isolate the target edge gateway node and the target smart device to obtain an isolated node area;

[0097] Step S43: Perform risk repair on the target smart device in the isolated node area.

[0098] It should be noted that in order to prevent problematic devices from affecting global terminal nodes, the target edge and the corresponding target smart device can be isolated in the smart device when there is risk data, and the isolated node area can be determined to avoid affecting the global system when performing risk repair, data testing, etc.

[0099] It is understandable that when the isolated node area is generated, risk repair can be performed on the target smart device in the isolated node area.

[0100] In one implementation of the embodiment of the present application, the step of updating the building node information based on the target edge gateway node and the target smart device after risk repair, and reconstructing the smart building contract according to the updated building node information includes:

[0101] Acquire updated device data of the smart device after risk repair through the target edge gateway node;

[0102] updating the building node information based on the update device data;

[0103] Reconstruct the smart building contract according to the updated building node information.

[0104] It is understood that when the risk is repaired, the management device can obtain updated device data of the remediated smart device based on the target edge gateway node, such as the replaced air conditioner model and post-repair usage data. Based on this updated device data, the building node information can be updated, and the smart building contract can be restructured, allowing the smart building contract to be updated in real time based on changes in the building during use.

[0105] When risk data exists, the present embodiment determines the target edge gateway node and target smart device corresponding to the risk data; isolates the target edge gateway node and target smart device to obtain an isolated node region; and performs risk remediation on the target smart device in the isolated node region. Because the target edge gateway node and target smart device are isolated first, the impact of irrelevant data on the global system during the risk remediation process is avoided.

[0106] It should be noted that the above examples are only used to understand this application and do not constitute a limitation on the smart building contract management method of this application. More simple transformations based on this technical concept are all within the scope of protection of this application.

[0107] This application also provides a smart building contract management device, please refer to Figure 5 , the smart building contract management device includes:

[0110] a risk data assessment module 30 for performing a risk assessment on the device data using a preset risk model to determine whether risk data exists in the device data;

[0111] The risk device repair module 40 is used to perform risk repair on the target edge gateway node and target smart device corresponding to the risk data when risk data exists;

[0112] The node information updating module 50 is used to update the building node information based on the target edge gateway node and the target smart device after risk repair, and reconstruct the smart building contract according to the updated building node information.
