This will form a network based on the Internet as an information carrier, allowing all independently addressable devices to interconnect.

[0003] Before forming the Internet of Things, the device needs to be registered in the Internet of Things platform. After the device is registered in the Internet of Things platform, in order to decouple the device from the application of the Internet of Things platform, the device shadow is provided in the relevant technology.

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] In order to solve the problems existing in the prior art, the embodiments of the present invention provide an Internet of Things device management method, apparatus, electronic device and storage medium to reduce the load pressure of the Internet of Things platform.

[0068] Next, a method for managing an IoT device according to an embodiment of the present invention is first described. Figure 1 FIG. 1 is a flowchart of a first implementation of a method for managing an IoT device according to an embodiment of the present invention. The method may include:

[0069] S110, obtaining object model information of a device registered to the Internet of Things platform, and establishing a device shadow corresponding to the device based on the object model information;

[0070] S120, synchronizing the device shadow to the device, so that when the device collects the device information, the device performs a corresponding operation based on the synchronized device shadow.

[0071] In some examples, the IoT platform of the embodiment of the present invention may be connected to multiple devices, which may be devices of the same type or devices of different types, which is not limited here. Before connecting a device to the IoT platform, the device may be registered to the IoT platform of the embodiment of the present invention.

[0072] Specifically, the user can input the metadata of the device and the identification information of the device into the IoT platform, and then the IoT platform can find the device based on the address information of the device, and after finding the device, store the metadata of the device and the identification information of the device locally on the IoT platform. The metadata of the device may include: device model, device specifications, device manufacturer, etc. The address information of the device may include the physical address of the device, the IP address of the device, etc.

[0073] In some other examples, the IoT platform may search for address information of a device connected to the IoT platform based on a user's search instructions, and after searching for the address information of the device, display it so that the user can enter metadata of the device corresponding to the address information of the device.

[0074] In this way, the device can be registered to the IoT platform. Then the user can input the object model information of the device to the IoT platform.

[0075] In some examples, the IoT platform may be connected to a backend device, which may include: a mobile terminal, a personal computer, a tablet computer, and other terminals.

[0076] The user can input the physical model information of the device in the back-end device, and then send the physical model information of the device to the above-mentioned Internet of Things platform, so that the Internet of Things platform can obtain the physical model information of the device.

[0077] The object model information is to digitize the actual physical device into a data model composed of attributes, services, and events, which is convenient for cloud management and data interaction. Its essence is a JSON (JavaScript Object Notation) description document. One physical device corresponds to one object model.

[0078] In some examples, the above-mentioned device registered with the Internet of Things platform may be installed with an information collection device, for example, a sensor, a camera, etc. Therefore, the device can collect device information.

[0079] When the device collects the device information, in order to avoid the device sending the device information to the IoT platform for processing, so as to reduce the load pressure of the IoT platform. After obtaining the object model information, the above-mentioned IoT platform can establish the device shadow corresponding to the device based on the object model information; and synchronize the device shadow to the device, so that when the device collects the device information, it can perform the corresponding operation based on the synchronized device shadow, without sending the device information to the IoT platform for processing, thereby reducing the load pressure of the IoT platform.

[0080] In some examples, a device shadow is a digital representation of a physical device in the real world.

[0081] An Internet of Things device management method provided by an embodiment of the present invention can establish a device shadow corresponding to the device based on the object model information when the object model information of the device registered to the Internet of Things platform is obtained; and then synchronize the device shadow to the device. In this way, when the device collects the device information, the device performs the corresponding operation based on the synchronized device shadow without sending the device information to the Internet of Things platform for processing, thereby reducing the load pressure of the Internet of Things platform.

[0082] exist Figure 1 Based on the IoT device management method shown in FIG. 1 , the embodiment of the present invention further provides a possible implementation method, such as Figure 2 FIG. 1 is a flow chart of a second implementation of a method for managing an IoT device according to an embodiment of the present invention. The method may include:

[0083] S210, when the device is registered to the IoT platform, a software development kit including a preset device shadow is sent to the device, so that the device locally saves the preset device shadow;

[0084] S220, obtaining object model information of a device registered to the IoT platform, and establishing a device shadow corresponding to the device based on the object model information;

[0085] S230, sending the device shadow to the device so that the device synchronizes the device shadow to the preset device shadow, obtains the synchronized device shadow, and performs corresponding operations based on the synchronized device shadow when the device information is collected.

[0086] In some examples, in order to facilitate synchronization of device shadows in subsequent steps, preset device shadows can be set in advance in the IoT platform.

[0087] Among them, each parameter in the preset device shadow can be empty. In this way, the preset device shadow can be made into a universal device shadow. Therefore, when the device is registered to the Internet of Things platform, the software development kit containing the universal device shadow can be sent to the above-mentioned device for storage.

[0088] In some other examples, corresponding device shadows can be pre-set for different types of devices in the above-mentioned IoT platform, and then when the device is registered to the IoT platform, a software development kit containing the device shadow corresponding to the type of device is sent to the device for storage.

[0089] After sending the software development kit to the device, when the Internet of Things platform obtains the object model information, it can establish a device shadow corresponding to the device based on the object model information, and then send the device shadow to the device. In this way, the device can synchronize the device shadow sent by the Internet of Things platform to the preset device shadow, thereby obtaining the synchronized device shadow.

[0090] In some examples, the IoT platform may send the parameters of the device shadow to the device, so that after acquiring the parameters of the device shadow, the device may use the parameters of the device shadow to replace the preset parameters of the device shadow, thereby obtaining a synchronized device shadow.

[0091] In the embodiment of the present invention, by using a software development kit, it is possible to conveniently deploy a device shadow in a device when the device is registered to an Internet of Things platform, thereby facilitating a subsequent synchronization process and reducing the time overhead of the synchronization process.

[0092] In some examples, some devices usually have boundary conditions, which may be the temperature range, pressure range, etc. of the working environment. Correspondingly, under different boundary conditions, there should be corresponding event operations. Therefore, the user can input the boundary conditions and corresponding event operations as object models into the above-mentioned Internet of Things platform.

[0093] Based on this, Figure 1 Based on the IoT device management method shown in FIG. 1 , the embodiment of the present invention further provides a possible implementation method, such as Figure 3 FIG. 1 is a flowchart of a third implementation of a method for managing an IoT device according to an embodiment of the present invention. The method may include:

[0094] S310, obtaining object model information of a device registered to the Internet of Things platform, and establishing a device shadow corresponding to the device based on the object model information;

[0095] S320, synchronizing the device shadow including the boundary conditions and the corresponding event operations to the device, so that when the device information is collected, the device performs the corresponding event operations based on the device information and the boundary conditions.

[0096] When the user inputs the boundary conditions and corresponding event operations as a physical model into the above-mentioned IoT platform, the IoT platform can obtain the physical model information including the boundary conditions and the corresponding event operations, and then establish a device shadow corresponding to the device based on the physical model information.

[0097] After obtaining the device shadow, the above-mentioned Internet of Things platform can synchronize the device shadow including the boundary conditions and the corresponding event operations to the device. In this way, when the device collects the device information, it can perform the corresponding event operations based on the device information and the boundary conditions.

[0098] Specifically, when the above-mentioned device performs corresponding event operations based on the device information and boundary conditions, it may send an alarm message to the above-mentioned Internet of Things platform when the device information exceeds the boundary conditions, or send the device information to the above-mentioned Internet of Things platform when the device information does not exceed the boundary conditions.

[0099] In some examples, the aforementioned IoT platform is also connected to a control terminal. When the IoT platform obtains alarm information fed back by the device based on the collected device information and boundary conditions, the alarm information can be sent to the aforementioned control terminal.

[0100] Or when the device information fed back by the device is obtained, the device information is sent to the above-mentioned control terminal.

[0101] In some examples, events of different importance should have different priorities. Based on this, the user can set the first operation priority information corresponding to the boundary condition. Therefore, the object model information obtained by the above-mentioned Internet of Things platform can also include: the first operation priority information corresponding to the boundary condition.

[0102] At this time, the above-mentioned Internet of Things platform can synchronize the device shadow containing boundary conditions, corresponding event operations and first operation priority information to the device, so that when the device collects device information, it performs the corresponding event operation based on the device information, boundary conditions and first operation priority information.

[0103] For example, assuming the boundary conditions are that the working temperature is -50℃~250℃ and the working pressure is 1MPa~5MPa. The first operation priority information is: the alarm information of the working pressure higher than 5MPa or lower than 1MPa is the first priority, and the alarm information of the working temperature lower than -50℃ or higher than 250℃ is the second priority. If the device information is the temperature of -51℃ and the pressure of 5.1MPa, the above device will give priority to sending the alarm information of the working pressure higher than 5MPa to the above IoT platform.

[0104] In the embodiment of the present invention, by setting different priorities for different event operations, more important event operations can be executed first.

[0105] In some examples, changes in device information usually have some trends, such as the changing trend of working temperature or the changing trend of working pressure. In order to predict the device information of the device based on the trend in advance so as to remind the user in advance, the user can input the trend conditions of the device and the corresponding event operations as a physical model into the above-mentioned Internet of Things platform.

[0106] Based on this, Figure 1 Based on the IoT device management method shown in FIG. 1 , the embodiment of the present invention further provides a possible implementation method, such as Figure 4 FIG. 1 is a flowchart of a fourth implementation of a method for managing an IoT device according to an embodiment of the present invention. The method may include:

[0107] S410, obtaining object model information of a device registered to the Internet of Things platform, and establishing a device shadow corresponding to the device based on the object model information;

[0108] S420, synchronize the device shadow including the trend conditions and the corresponding event operations to the device, so that when the device collects the device information, it determines the information change of the device based on the collected device information and the historical device information, and performs the corresponding event operation based on the information change of the device and the trend conditions.

[0109] When the user inputs the trend condition and the corresponding event operation as a physical model into the above-mentioned IoT platform, the IoT platform can obtain the physical model information including the trend condition and the corresponding event operation, and then establish the device shadow corresponding to the device based on the physical model information.

[0110] After obtaining the device shadow, the above-mentioned Internet of Things platform can synchronize the device shadow containing trend conditions and corresponding event operations to the device. In this way, when the device collects device information, it determines the information changes of the device based on the collected device information and historical device information, and then performs corresponding event operations based on the information changes and trend conditions of the device.

[0111] Specifically, when the above-mentioned device performs corresponding event operations based on the information changes and trend conditions of the device, it may send an alarm message to the above-mentioned Internet of Things platform when the information change is greater than or equal to the trend condition, or send device information to the above-mentioned Internet of Things platform when the information change is less than the trend condition.

[0112] In some examples, the above-mentioned Internet of Things platform is also connected to a control terminal. When the Internet of Things platform obtains alarm information fed back by the device based on the collected device information, historical device information and trend conditions, the alarm information can be sent to the above-mentioned control terminal.

[0113] Or when the device information fed back by the device is obtained, the device information is sent to the above-mentioned control terminal.

[0114] In some examples, events of different importance should have different priorities. Based on this, the user can set the second operation priority information corresponding to the trend condition. Therefore, the object model information obtained by the above-mentioned Internet of Things platform can also include: the second operation priority information corresponding to the trend condition.

[0115] At this time, the above-mentioned Internet of Things platform can synchronize the device shadow containing trend conditions, corresponding event operations and second operation priority information to the device, so that when the device collects device information, it determines the information changes of the device based on the collected device information and historical device information, and compares the information changes with the trend conditions; and when the information changes do not meet the trend conditions, the event operations corresponding to the trend conditions are executed based on the second operation priority information.

[0116] For example, assuming that the trend condition is that the rate of change of the working temperature is less than or equal to 10°C / h, and the rate of change of the working pressure is less than or equal to 0.1MPa / h. The first operation priority information is: the alarm information of the rate of change of the working pressure is greater than 0.1MPa / h is the first priority, and the alarm information of the working temperature is greater than 10°C / h is the second priority. When the rate of change of the working temperature in the obtained device information is 11°C / h and the rate of change of the working pressure is 0.11MPa / h, the above-mentioned device will give priority to sending the alarm information of the rate of change of the working pressure greater than 0.1MPa / h to the above-mentioned Internet of Things platform.

[0117] exist Figure 1 Based on the IoT device management method shown in FIG. 1 , the embodiment of the present invention further provides a possible implementation method, such as Figure 5 FIG. 1 is a flowchart of a fifth implementation of a method for managing an IoT device according to an embodiment of the present invention. The method may include:

[0118] S510, acquiring object model information and device status information, and establishing a device shadow corresponding to the device and version information of the device shadow based on the object model information and the status information;

[0119] S520, when receiving a version switching instruction, determine the device shadow of the target version based on the version information of the device shadow, and synchronize the device shadow of the target version to the device, so that when the device collects the device information, it performs corresponding operations based on the synchronized device shadow of the target version.

[0120] In some examples, when the user inputs object model information each time, the above-mentioned Internet of Things platform can establish version information of the device shadow when establishing the device shadow based on the object model information obtained each time.

[0121] In some other examples, the above-mentioned user can also input the status information of the device each time when inputting the physical model information. Therefore, the above-mentioned Internet of Things device can establish a device shadow corresponding to the device containing the physical model information and the status information, as well as the version information of the device shadow based on the input physical model information and the status information of the device.

[0122] The state information of the device may include: state metadata, expected value, collected device information, etc. The state metadata may include information such as the time when the collected device information of the device changes.

[0123] In some other examples, when the user inputs the status information of the device, the collected device information in the status information may be empty or set to 0.

[0124] In some other examples, the user can also input the change rules of the device shadow version information, and then the above-mentioned Internet of Things platform can establish new version information according to the change rules of the version information and the historical version information each time the device shadow version information is established.

[0125] After the above-mentioned IoT platform establishes the device shadow corresponding to the device and the version information of the device shadow each time, the device shadow corresponding to the device and the version information of the device shadow can be saved accordingly. In this way, when a version switching instruction is received, the device shadow of the target version can be determined based on the saved version information of multiple device shadows, and the device shadow of the target version can be synchronized to the device, so that when the device collects the device information, the device can perform the corresponding operation based on the synchronized device shadow of the target version.

[0126] exist Figure 1 Based on the IoT device management method shown in FIG. 1 , the embodiment of the present invention further provides a possible implementation method, such as Figure 6 As shown, it is a signaling interaction diagram of the Internet of Things management system of an embodiment of the present invention. The Internet of Things management system may include: a control terminal, an Internet of Things management platform and a device, wherein a Twins module may be provided in the Internet of Things management platform, and the Twins module may communicate with the Web page of the control terminal through the communication module of the Internet of Things management platform, and may also communicate with the device.

[0127] The device can be pre-registered with the IoT platform, and the IoT platform can then send a locally stored SDK to the device.

[0128] Then, when the user inputs the object model information and status information of the device on the Web page, the Web page can send the object model information and status information of the device to the Twins module through the communication module of the control terminal.

[0129] When the Twins module receives the object model information and status information of the device, it can establish the device shadow corresponding to the device and the version information of the device shadow based on the object model information and status information of the device, and then send the device shadow corresponding to the device to the device.

[0130] After receiving the device shadow corresponding to the device, the device can synchronize the device shadow and then determine whether the collected device information exceeds the boundary conditions; when the collected device information exceeds the boundary conditions, an alarm message is sent to the above-mentioned Twins module; when the collected device information does not exceed the boundary conditions, the device information is sent to the above-mentioned Twins module.

[0131] The above-mentioned Twins module can also determine the information changes of the equipment based on the collected equipment information and historical equipment information, and judge whether the information changes meet the trend conditions. When the information changes do not meet the trend conditions, an alarm message is sent to the above-mentioned Twins module; when the information changes meet the trend conditions, the equipment information is sent to the above-mentioned Twins module.

[0132] After receiving the alarm information or device information, the Twins module may send the alarm information or device information to a Web page to remind the user or allow the user to browse the device information.

[0133] In some examples, the user may also input an expected value of the device status information, and the web page may send the expected value of the device status information to the Twins module. The Twins module may then change the device status information based on the expected value of the device status information.

[0134] In some other examples, the above-mentioned device may be online or offline. In this regard, the above-mentioned Twins module can monitor whether the device is online. If it is online, the changed device status information is sent to the device so that the device can change the device status information in the locally stored device shadow.

[0135] In some examples, a user may input a version switching instruction of a device shadow on a web page, and then the web page may send the version switching instruction of the device shadow to the Twins module. Upon receiving the version switching instruction, the Twins module may determine the device shadow of the target version based on the version information of multiple device shadows saved, and synchronize the device shadow of the target version to the device, so that when the device collects device information, the device may determine whether the collected device information exceeds the boundary conditions in the device shadow of the target version, or determine whether the information change corresponding to the collected device information satisfies the trend conditions in the device shadow of the target version, and then perform the corresponding operation.
