[0044] It is found through research that, with the rapid development of Internet of Things (IoT) technology, the number of devices connected to the Internet has increased dramatically, which also leads to a challenge in the association of the Internet of Things, especially in the case of large-scale and widely distributed devices. At present, cloud devices are used to access devices for end-side devices to improve the access efficiency of end-side devices. However, when cloud devices are used to access devices for end-side devices, data congestion often occurs, which may cause end-side device access to be blocked, and even access failure may occur.

[0046] The application content will be further described by describing the embodiments in combination with the drawings.

[0047] The embodiments provide a cloud-based batch access method, as shown in Figure 1 The method comprises the following steps.

[0048] S10, obtaining device network information corresponding to an end-side device, and determining a data packet to be sent to the end-side device based on the obtained device network information.

[0049] Specifically, the end-side device is a target device that an access device wants to access, wherein the end-side device is taken as a control device, and the access device corresponding to the end-side device can be taken as a controlled device. For example, as shown in Figure 2As shown in the figure, the end-side device is a conference room presence controller, the access devices are an air conditioner and a sensor, the controller is the control device, and the air conditioner and the sensor are the controlled devices of the access control device.

[0050] The device network information includes the end-side device and the access devices corresponding to the end-side device, the access devices corresponding to the end-side device are multiple, and the multiple access devices are caused to access the end-side device in batches through the device network information. The multiple access devices can all be unknown devices of the end-side device, or part of the multiple access devices can be unknown devices of the end-side device, that is, at least one access device in the multiple access devices is unknown to the end-side device, and the physical model information of the access device and the access relationship between the access device and the end-side device are unknown to the end-side device. The cloud-based batch access method provided in the application is mainly applied to the case that the end-side device needs to access multiple unknown access devices in batches, or the case that the end-side device needs to access all the access devices corresponding to the end-side device in batches. When one or a small number of unknown access devices need to be accessed, the device network information formed by only one or a small number of unknown access devices and the end-side device can be used to avoid the problem of data congestion. Of course, when one or a small number of unknown access devices need to be accessed, the cloud-based batch access method provided in the application can also be used.

[0051] The device network information can include the topology between the end-side device and the access devices corresponding to the end-side device, the physical model information of the end-side device, and the physical model information of the access devices corresponding to the end-side device. The device network information can reflect the system information of the Internet of Things system formed by the end-side device and the access devices corresponding to the end-side device, for example, the end-side device is a conference room presence controller, and the access devices are an air conditioner and a sensor. The device network information reflects the system information of the Internet of Things system formed by the controller, the air conditioner, and the sensor. The device network information includes the topology between the end-side device and the access devices corresponding to the end-side device and the physical model information of the end-side device and the access devices corresponding to the end-side device, the topology adopts a structure tree form, the end-side device is a root node in the structure tree, and the access devices corresponding to the end-side device are leaf nodes in the structure tree.

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

[0053]

[0054]

[0055]

[0056] ​In an implementation, before the obtaining the device network information corresponding to the end-side device, the method further comprises:

[0057] receiving a binding operation input by a user;

[0058] obtaining an end-side device and an access device corresponding to the binding operation, and constructing the device network information of the end-side device based on the obtained end-side device and the access device.

[0059] Specifically, the binding operation is used to bind the access device for the end-side device, and through the binding operation, part of the access devices or all of the access devices corresponding to the end-side device can be obtained. That is, the access devices corresponding to the end-side device can be realized by responding to one binding operation, or can be realized by responding to multiple binding operations, and when realized by responding to multiple binding operations, the multiple binding operations can be independent of each other, that is, the cloud device can be sent the binding operation at different time periods or in different situations to inform the cloud device that the access device needs to be added for the end-side device. Therefore, when the access device needs to be accessed to the end-side device, all of the access devices corresponding to the end-side device can be obtained, and then all of the access devices are sent to the cloud device, so that the cloud device reconstructs the device network information based on all of the access devices to update the access devices corresponding to the end-side device; or only the access device that needs to be newly accessed to the end-side device can be sent, and then the device network information of the existing end-side device is updated based on the access device. No matter which way is used to update the device network information of the end-side device, the new access device can be dynamically accessed to the end-side device, and the scalability of the function of the end-side device is realized.

[0060] Further, the binding operation can directly carry the access device and the access relationship between the access device and the end-side device. After receiving the binding operation, the access device and the access relationship between the access device and the end-side device written in the binding operation can be directly read, the physical model information of the access device can be obtained, the topology between the end-side device and the access device can be constructed based on the access relationship, and the physical model information of the end-side device and the access device can be added to the topology to form the device network information. In addition, the binding operation can carry the position information and the control range corresponding to the end-side device. After receiving the binding operation, the position information and the control range of the end-side device can be read, and then the access device corresponding to the end-side device can be determined based on the position information and the control range. Specifically, the first position information and the control range of the end-side device can be read first, and the control area of the end-side device can be determined with the first position information as the center and the control range as the radius. Then, the second position information of the known product device is read, and the access device located in the control area is selected based on the second position information and the control area to obtain the access device corresponding to the end-side device. In addition, after selecting the access device located in the control area, all selected access devices can be directly used as the access device corresponding to the end-side device, or the access device not connected to the end-side device and the access device connected to the end-side device can be used as the access device corresponding to the end-side device.

[0061] S20, determining the sending mode of the data message according to the message data amount of the data message, and sending the data message to the end-side device according to the sending mode.

[0062] Specifically, the message data amount is used to reflect the message size of the data message. After obtaining the data message, the data size of the data message can be read to obtain the message data amount. For example, the cloud device and the end-side device interact data through the MQTT protocol. When the data message conforms to the message of the MQTT protocol, the field corresponding to the message size can be determined through the format of the message of the MQTT protocol, and then the message data amount of the data message can be obtained by reading the field. The sending mode is the form of sending the data message between the cloud device and the end-side device. The sending mode can be determined based on the data amount of the data message. Different sending modes can be used for different data amounts of the data message, so that the problem of data congestion caused by too large data amount of the data message can be avoided.

[0063] In one implementation manner, as shown in Figure 2 the determination of the sending mode of the data message according to the message data amount of the data message, and the sending of the data message to the end-side device according to the sending mode specifically includes:

[0064] S21, comparing the message data amount of the data message with a preset threshold.

[0065] S22, if the message data volume is less than or equal to the preset threshold, sending the data message to the end-side device;

[0066] S23, if the message data volume is greater than the preset threshold, dividing the data message into a plurality of data message segments based on the preset threshold, and sending each data message segment in the plurality of data message segments to each end-side device.

[0067] Specifically, the preset threshold is pre-set, which can be the maximum data volume of the channel issued by the cloud device and the end-side device, or the limit value of the pre-device, etc. When the message data volume is less than or equal to the preset threshold, it means that the data message can be sent directly. When the message data volume is greater than the preset threshold, it means that direct sending of the data message may cause data congestion. Therefore, the data message can be divided into a plurality of data message segments based on the preset threshold, and then each data message segment in the plurality of data message segments is sent to each end-side device.

[0068] It should be noted that before determining the sending mode of the data message according to the message data volume of the data message, 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 the preset number threshold. When the number is less than or equal to the preset number threshold, the access device network information of the subsystem composed of the unknown access device and the end-side device can be selected in the device network information, and then the data message 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 message is determined based on the device network information, and the sending mode of the data message is determined according to the message data volume of the data message.

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

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

[0071] Specifically, the uniform division refers to that a difference of data amounts of each data message segment obtained by the division is within a preset range, each of the data message segments includes at least the physical model information of one access device, and a data amount of each data message segment is closest to a preset threshold. In this way, the end-side device can control the access of the access device included in the data message segment based on the data message segment when receiving the data message segment. Of course, in actual application, the data message can also be divided by the preset threshold as a division unit, so that the data amount of each data message segment except the last data message segment is equal to the preset threshold. In this way, the number of data message segments can be reduced, and then the sending times of the data message segments can be reduced.

[0072] In an implementation manner, after the respective sending of each data message segment in the data message segments to the respective end-side device, the method further includes:

[0073] receiving feedback information of the end-side device for each data message segment, and verifying the corresponding data message segment based on the feedback information;

[0074] if all the data message segments are verified, it is determined that the data message is sent completely;

[0075] if there is a data message segment that is not verified, it is determined that the data message is sent abnormally, and the abnormal data message segment is marked.

[0076] Specifically, when the data message is segmented and sent, one or more data message segments may be sent abnormally, so that the end-side device cannot receive the physical model information of all the access devices, and then some access devices fail to access. Based on this, after the respective sending of each data message segment to the end-side device, feedback information formed by the end-side device based on the data message segment is received. That is, after receiving the data message segment, the end-side device sends a feedback information to the cloud-side device to inform the cloud-side device of the receiving situation of the received data message segment, wherein the feedback information can include the data amount of the data message segment and the verification value of the access device included in the data message segment.

[0077] Further, the cloud-side device can first monitor whether the feedback information is received within a preset time. When the feedback information is not received, it is directly determined that the data message is sent abnormally, and the abnormal data message segment is marked. When the feedback information is received, the data message segment can be verified based on the information content included in the feedback information, for example, the integrity of the data message segment is verified based on the data amount of the data message segment, the correctness of the data message segment is verified based on the verification value of the access device, and when the integrity and the correctness are both verified, it is determined that the data message is sent completely, otherwise, when the integrity and / or the correctness is not verified, it is determined that the data message is sent abnormally, and the abnormal data message segment is marked.

[0078] In an implementation manner, after the data message is sent, the end-side device accesses the corresponding access device based on the device network information carried in the data message. That is, the method further comprises:

[0079] controlling the end-side device to determine the access relationship between the end-side device and the corresponding access device based on the topology structure between the end-side device and the corresponding access device;

[0080] downloading the physical model files of the end-side device and the physical model files of each access device based on the physical model information of the end-side device and the physical model information of each corresponding access device of the end-side device;

[0081] comparing the check values of each physical model file with the corresponding check values in the topology information;

[0082] if the comparison passes, dynamically loading each physical model file to access each access device to the end-side device according to the access relationship.

[0083] Specifically, the device network information includes the check values of the physical model information of each access device. After the end-side device downloads the physical model files of the end-side device and each corresponding access device, the physical model files downloaded by the end-side device to the end-side device and each corresponding access device can be checked by the check values to determine the accuracy of the physical model files downloaded by the end-side device to the end-side device and each corresponding access device.

[0084] Further, after the comparison passes, each physical model file is dynamically loaded, and then each access device is dynamically accessed to the end-side device according to the topology structure between the end-side device and each corresponding access device, thereby realizing batch access of the end-side device, improving the access efficiency of the end-side device, and saving the labor cost without manually accessing each access device one by one.

[0085] In summary, the embodiment provides a cloud-based batch access method, device, apparatus and storage medium. The method comprises obtaining device network information corresponding to an end-side device, and determining a data message to be sent to the end-side device based on the obtained device network information; determining a sending mode of the data message according to the message data amount of the data message, and sending the data message to the end-side device according to the sending mode. When the data message of batch access is issued to the end-side device, the sending mode is determined according to the message data amount of the data message, which can avoid the problem of data congestion caused by too large data amount of the data message, and further avoid the problem of access failure caused by data congestion.
