[0044] After research, it was found that with the rapid development of Internet of Things (IoT) technology, the number of devices connected to the Internet has increased dramatically, which has also made the connection of IoT a challenge, especially when the devices are large-scale and widely distributed. At present, cloud devices are used to connect devices to end-side devices to improve the access efficiency of end-side devices. However, when using cloud devices to connect devices to end-side devices, data blocking problems often occur, which in turn causes the end-side device to be stuck in access or even access failure.

[0045] In order to solve the above problems, in an embodiment of the present application, the device network information corresponding to the terminal device is obtained, and the data message to be sent to the terminal device is determined based on the obtained device network information; the sending method of the data message is determined according to the message data volume of the data message, and the data message is sent to the terminal device according to the sending method. When the present application sends batch access data messages to the terminal device, the sending method will be determined according to the message data volume of the data message, which can avoid the problem of data blocking caused by the excessive data volume of the data message, and further avoid the problem of access failure caused by data blocking.

[0046] The application content is further explained below through the description of embodiments in conjunction with the accompanying drawings.

[0047] This embodiment provides a cloud-based batch access method, such as Figure 1 As shown, the method includes:

[0048] S10: Acquire device network information corresponding to the end-side device, and determine a data message to be sent to the end-side device based on the acquired device network information.

[0049] Specifically, the terminal device is the target device that the access device wants to access, wherein the terminal device is used as a control device, and the access device corresponding to the terminal device can be used as a controlled device. Figure 2As shown, the end-side device is a conference room controller, and the access devices are an air conditioner and a sensor. The controller serves as a control device, and the air conditioner and the sensor serve as controlled devices accessing the control device.

[0050] The device network information includes the terminal side device and the access device corresponding to the terminal side device. There are multiple access devices corresponding to the terminal side device, and the device network information is used to prompt multiple access devices to access the terminal side device in batches. Among them, the multiple access devices can all be devices unknown to the terminal side device, or they can be devices that are partially unknown to the terminal side device, that is, at least one access device among the multiple access devices, and the physical model information of the access device and the access relationship between the access device and the terminal side device are unknown to the terminal side device. The cloud-based batch access method provided in the present application is mainly used in the case where the terminal side device needs to access multiple unknown access devices in batches, or in the case where all access devices corresponding to the terminal side device need to be re-accessed. When it is necessary to access one or a small number of unknown access devices, the device network information composed of only one or a small number of unknown access devices and the terminal side devices can be used to avoid data congestion. Of course, when it is necessary to access one or a small number of unknown access devices, the cloud-based batch access method provided in the present application can also be used.

[0051] The device network information may include the topological structure between the end-side device and its corresponding access device, the physical model information of the end-side device and the physical model information of its corresponding access device. The device network information may reflect the system information of the Internet of Things system formed by the end-side device and the access device corresponding to the end-side device. For example, if the end-side device is a conference room with a controller, and the access device is an air conditioner and a sensor, then the device network information reflects the system information of the Internet of Things system formed by the controller, the air conditioner and the sensor. Among them, the device network information includes the topological structure between the end-side device and its corresponding access device and the physical model information of the end-side device and its corresponding access device. The topological structure is in the form of a structure tree, the end-side device is the root node in the structure tree, and the access device corresponding to the end-side device is the leaf node in the structure tree.

[0052] For example: Figure 2 As shown in the figure, the end-side device is a conference room controller, and the access devices are an air conditioner and a sensor. Then the data structure of the device network information of the end-side device is:

[0053]

[0054]

[0055]

[0056] In one implementation, before obtaining the device network information corresponding to the terminal device, the method further includes:

[0057] Binding operations that receive user input;

[0058] The terminal side device and the access device corresponding to the binding operation are obtained, and the device network information of the terminal side device is constructed based on the obtained terminal side device and the access device.

[0059] Specifically, the binding operation is used to bind the access device to the terminal device, and the binding operation can obtain some or all access devices corresponding to the terminal device. That is to say, the access device corresponding to the terminal device can be realized by responding to a single binding operation, or by responding to multiple binding operations, and when it is realized by responding to multiple binding operations, the multiple binding operations can be independent of each other, that is, the binding operation can be sent to the cloud device in different time periods or under different circumstances to inform the cloud device that an access device needs to be added for the terminal device. It can be seen that when the access device needs to be accessed to the terminal device, all access devices corresponding to the terminal device can be obtained, and then all access devices are sent to the cloud device, so that the cloud device reconstructs the device network information based on all access devices to update the access device corresponding to the terminal device; or, only the access device that needs to be newly accessed to the terminal device can be sent, and then the device network information of the existing terminal device can be updated based on the access device. Regardless of the method used to update the device network information of the terminal device, new access devices can be dynamically accessed for the terminal device, realizing the scalability of the terminal device function.

[0060] Furthermore, the binding operation can directly carry the access device and the access relationship between the access device and the terminal device. Then, after receiving the binding operation, the access device and the access relationship between the access device and the terminal device written by the binding operation can be directly read, the physical model information of the access device can be obtained, and the topological structure between the terminal device and the access device can be constructed based on the access relationship, and the physical model information of the terminal device and the access device can be added to the topological structure to form device network information. In addition, the binding operation can carry the location information and control range corresponding to the terminal device. Then, after receiving the binding operation, the location information and control range of the terminal device can be read, and then the access device corresponding to the terminal device can be determined based on the location information and control range. Specifically, the first location information and control range of the terminal device can be read first, and the control area of ​​the terminal device can be determined with the first location information as the center and the control range as the radius; then the second location information of the known product device can be read, and the access device located in the control area can be selected based on the second location information and the control area to obtain the access device corresponding to the terminal device. In addition, after selecting the access devices located in the control area, all the selected access devices are directly used as the access devices corresponding to the end-side devices. The selected access devices that are not connected to the end-side devices and the access devices connected to the end-side devices can also be used as the access devices corresponding to the end-side devices, etc.

[0061] S20. Determine a sending mode of the data message according to the message data volume of the data message, and send the data message to the terminal side device according to the sending mode.

[0062] Specifically, the message data volume is used to reflect the message size of the data message. After the data message is obtained, the data size of the data message can be read. For example, the cloud device and the end-side device exchange data through the MQTT protocol. Then, in the message that conforms to the MQTT protocol, the field corresponding to the message size can be determined through the format of the MQTT protocol message, and then the message data volume of the data message can be obtained by reading the field. The sending mode is the form of sending data messages between the cloud device and the end-side device, which can be determined based on the data volume of the data message. By using different sending modes for data messages with different data message volumes, data congestion caused by excessive data volume of data messages can be avoided.

[0063] In one implementation, if Figure 2 As shown, determining the sending mode of the data message according to the message data volume of the data message, and sending the data message to the terminal side device according to the sending mode specifically includes:

[0064] S21, comparing the message data volume of the data message with a preset threshold;

[0065] S22: If the data volume of the message is less than or equal to the preset threshold, send the data message to the terminal side device;

[0066] S23. If the data volume of the message is greater than the preset threshold, the data message is divided into a plurality of data message segments based on the preset threshold, and each of the plurality of data message segments is sent to each end-side device respectively.

[0067] Specifically, the preset threshold is preset, which may be the maximum amount of data that can be accommodated in the channel between the cloud device and the terminal device, or a limit value of the pre-set device, etc. When the amount of message data is less than or equal to the preset threshold, it means that the data message can be sent directly, and when the amount of message data is greater than the preset threshold, it means that data congestion may occur if the data message is sent directly. Therefore, the data message may be divided into a plurality of data message segments based on the preset threshold, and then each of the plurality of data message segments is sent to each terminal device respectively.

[0068] It should be noted that before determining the sending method of the data packet according to the message data volume of the data packet, the number of unknown access devices that need to access the end-side device can be obtained first, and then the number is compared with a preset number threshold. When the number is less than or equal to the preset number threshold, the access device network information of the subsystem consisting of the unknown access device and the end-side device can be selected from the device network information, and then the data packet determined by the access device network information is sent to the end-side device; when the number is greater than the preset number threshold, the data packet is determined based on the device network information, and the sending method of the data packet is determined according to the message data volume of the data packet.

[0069] In one implementation, dividing the data message into a plurality of data message segments based on the preset threshold specifically includes:

[0070] The data message is evenly divided into a plurality of data message segments based on the preset threshold.

[0071] Specifically, uniform division means that the difference in the amount of data of each data segment obtained by division is within a preset range, each of the data segments includes at least one physical model information of an access device, and the amount of data of each data segment is close to the preset threshold to the greatest extent, so that the end-side device can control the access of the access device included in the data segment based on the data segment after receiving a data segment. Of course, in actual applications, the data segment can also be divided with the preset threshold as the division unit, so that the amount of data of each data segment is equal to the preset threshold except for the last data segment, which can reduce the number of data segments and further reduce the number of times the data segments are sent.

[0072] In one implementation, after sending each of the plurality of data message segments to each end-side device, the method further includes:

[0073] The receiving end side device verifies the corresponding data message segment based on the feedback information of each data message segment;

[0074] If all data message segments pass the verification, it is determined that the data message has been sent;

[0075] If there is a data message segment that fails the verification, it is determined that the data message sending is abnormal, and the abnormal data message segment is marked.

[0076] Specifically, when sending data packets in segments, one or more data packet segments may be sent abnormally, resulting in the end-side device being unable to receive the physical model information of all access devices, thereby causing access failure of some access devices. Based on this, after sending each data packet segment to the end-side device, feedback information generated by the end-side device based on the packet data segment will be received. In other words, after receiving the data packet segment, the end-side device will send a feedback message to the cloud device to inform the cloud device of the reception status of the received data packet segment, wherein the feedback information may include the amount of data in the data packet segment and the checksum value of the access device included in the data packet segment, etc.

[0077] Furthermore, the cloud device may first monitor whether feedback information is received within a preset time, and when no feedback information is received, directly determine that the data message sending is abnormal, and mark the abnormal data message segment; after receiving the feedback information, the data message segment may be verified based on the information content included in the feedback information, for example, the integrity of the data message segment may be verified based on the data volume of the data message segment, and the correctness of the data message segment may be verified based on the check value of the access device, and when both the integrity and correctness are verified, it is determined that the data message is sent, otherwise, when the integrity and / or correctness verification fails, it is determined that the data message sending is abnormal, and the abnormal data message segment is marked.

[0078] In one implementation, after the data message is sent, the terminal device will access its corresponding access device based on the device network information carried by the data message. That is, the method also includes:

[0079] Controlling the terminal side device to determine an access relationship between the terminal side device and its corresponding access device based on a topological structure between the terminal side device and its corresponding access device;

[0080] Downloading the physical model file of the terminal side device and the physical model files of each access device based on the physical model information of the terminal side device and the physical model information of each access device corresponding to the terminal side device;

[0081] Compare the checksum of each physical model file with the corresponding checksum in the topology information;

[0082] If the comparison is successful, each object model file is dynamically loaded to connect each access device to the terminal side device according to the access relationship.

[0083] Specifically, the device network information includes the verification value of the physical model information of each access device. After the end-side device downloads the physical model files to the end-side device and its corresponding access devices, the physical model files downloaded by the end-side device to the end-side device and its corresponding access devices can be verified by the verification value to determine the accuracy of the physical model files downloaded by the end-side device to the end-side device and its corresponding access devices.

[0084] Furthermore, after the comparison is passed, each object model file is dynamically loaded, and then each access device is dynamically connected to the end-side device according to the topological structure between the end-side device and its corresponding access device, thereby realizing batch access of end-side devices, improving the access efficiency of end-side devices, and eliminating the need to manually connect each access device one by one, saving labor costs.

[0085] In summary, the present embodiment provides a cloud-based batch access method, apparatus, device and storage medium, the method comprising obtaining device network information corresponding to the end-side device, and determining the data message to be sent to the end-side device based on the obtained device network information; determining the sending method of the data message according to the message data volume of the data message, and sending the data message to the end-side device according to the sending method. When the present application sends batch access data messages to the end-side device, it will determine the sending method according to the message data volume of the data message, which can avoid the problem of data congestion caused by the excessive data volume of the data message, and further avoid the problem of access failure caused by data congestion.
