[0037] According to one aspect of the embodiments of this application, a method for accessing an Internet of Things sub-device is provided.

[0038] Combined with Figure 1 As shown, the access system of the Internet of Things sub-devices includes the Internet of Things platform 20, the gateway device 10, and the ncp (Network Coordinator Processor) module 30.

[0039] The gateway device 10 includes a gateway protocol parser 101, a gateway main service 102, and a gateway host 103. The gateway protocol parser 101 is connected to the Internet of Things cloud platform 20. The gateway main service 102 is respectively connected to the gateway protocol parser 101 and the gateway host 103. The gateway main service 102 is connected to the ncp module Host application layer 30.

[0040] Among them, the ncp module Host application layer 30 is used to process tasks at the network layer and application layer, and realize the network access of the Internet of Things sub-devices.

[0041] The gateway protocol parser 101 is a software development kit, which has the ability to manage Internet of Things devices. Among them, the gateway protocol parser 101 is configured with a dynamic library.

[0042] The gateway main service 102 represents the service of the core functions running in the gateway device, which has the ability to process key business logics. The gateway main service 102 also has the capabilities of data storage, communication, and communication with other components.

[0043] The gateway host side 103 represents a device or software entity that acts as a host or a central node in the network. Among them, the above-mentioned network includes ZigBee, Bluetooth Mesh, or WiFi, or a wired network.

[0044] Based on the software and hardware configuration of the access system for the above-mentioned IoT sub-devices, combined with Figure 2 As shown, an embodiment of the present disclosure provides an access method for IoT sub-devices, including:

[0045] S01, the gateway protocol parser sends a firmware download request to the IoT cloud platform to request the download of protocol data packets, and the protocol data packets include a new version of the gateway protocol parser and a sub-device model information file supported by the gateway protocol parser.

[0046] In this step, the sub-device model information file includes a file encapsulated by sub-device model information. As an example, the sub-device model information file includes a sub-device model information list. The sub-device model information list includes a list of IoT sub-device models supported by the gateway protocol parser. Each list of IoT sub-device models includes device information of the IoT sub-device, and the device information includes some or all of the device name, device type, device function attribute template, device model, and device heartbeat reporting period.

[0047] It should be noted that the IoT sub-devices corresponding to the protocol data packets include one or more of the following:

[0048] IoT sub-devices in which templates are already stored in the ncp module Host application layer and the device function attributes are newly added.

[0049] IoT sub-devices in which templates are already stored in the ncp module Host application layer and the device models are updated.

[0050] IoT sub-devices in which templates are not stored in the ncp module Host application layer and the device information is newly added.

[0051] S02, the gateway protocol parser receives the firmware download response sent by the IoT platform and saves it. The firmware download response includes protocol data packets.

[0052] S03, the gateway protocol parser dynamically loads the gateway protocol parser based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file to achieve the hot update of the gateway protocol parser.

[0053] In this step, dynamically loading the gateway protocol parser based on the new version of the gateway protocol parser includes: dynamically loading the dynamic library of the gateway protocol parser based on the new version of the gateway protocol parser.

[0054] By adopting the access method of the Internet of Things sub-devices provided by the embodiments of the present disclosure, after the gateway protocol parser provided by the embodiments of the present disclosure sends a firmware download request to the Internet of Things platform to request the download of protocol data packets, it receives the firmware download response sent by the Internet of Things platform and saves it. The gateway protocol parser is dynamically loaded based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file carried in the protocol data packet, thereby realizing the hot update of the gateway protocol parser. When there is a need for a new model of Internet of Things sub-device to access the network, the embodiments of the present disclosure allow the gateway device to dynamically load or hot update according to the device access requirements without restarting the device or application, so as to complete the access of the new model of Internet of Things sub-device, without the need for a whole-machine version iteration, and shorten the time for operation and maintenance personnel to perform device upgrades and related configurations, improving the efficiency of product function iteration.

[0055] In addition, the gateway protocol parser provided by the embodiments of the present disclosure can reduce code branches, improve the maintainability and scalability of the code through componentization, serviceization and dynamic update mechanisms. At the same time, the embodiments of the present disclosure provide a unified Internet of Things sub-device access framework, enabling the same Internet of Things sub-device to access different platforms and realizing the fast access of Internet of Things sub-devices.

[0056] Optionally, the new version of the gateway protocol parser is developed in C language. In this way, it can support both Linux gateway devices and Android control panels, RTOS (Real Time Operate System) gateway devices at the same time. It has high portability and wide function coverage, high code execution efficiency, little impact on the performance of different platform systems, and is loaded and hot updated in the form of dynamic libraries on the Android platform and the Linux platform to achieve seamless update without downtime. In addition, by developing and writing in C language, cross-platform development can be realized, the device access framework can be unified, and the serviceization and componentization of the device protocol transfer and reuse module can be realized.

[0057] It should be noted that when the gateway device is configured with a Linux platform, the gateway main service is the jni-mpr-service service. In addition, the access method of the Internet of Things sub-devices provided by this application can be extended to wireless networks such as Bluetooth mesh and WiFi, or extended to wired networks such as 485.

[0058] Combined with Figure 3 shown, the embodiments of the present disclosure also provide an access method for Internet of Things sub-devices, including:

[0059] S11, the gateway protocol parser sends a firmware query request to the Internet of Things cloud platform to request to query whether the stored protocol data packet includes a new version of the gateway protocol parser.

[0060] In this step, the gateway protocol parser sends a firmware query request to the Internet of Things cloud platform to request a query on whether the stored protocol data packet includes a new version of the gateway protocol parser, including: the gateway protocol parser periodically sends a firmware query request to the Internet of Things cloud platform. Among them, the period for sending the firmware query request can be set according to specific requirements. As an example, the period for sending the firmware query request is N * 24h, where N is a positive integer and h represents hours. It can be understood that the period for sending the firmware query request can also be other values.

[0061] S12. The gateway protocol parser receives the firmware query response sent by the Internet of Things cloud platform, and the firmware query response includes the current version information of the stored protocol data packet.

[0062] S13. In the case where the current version information indicates that the stored protocol data packet includes a new version of the gateway protocol parser, the gateway protocol parser constructs a firmware download request.

[0063] S14. The gateway protocol parser sends a firmware download request to the Internet of Things cloud platform to request the download of the protocol data packet, and the protocol data packet includes a new version of the gateway protocol parser and the sub-device model information file supported by the gateway protocol parser.

[0064] S15. The gateway protocol parser receives and saves the firmware download response sent by the Internet of Things platform, and the firmware download response includes the protocol data packet.

[0065] S16. The gateway protocol parser dynamically loads the gateway protocol parser based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file to achieve the hot update of the gateway protocol parser.

[0066] Using the access method for IoT sub-devices provided by the embodiments of the present disclosure, before the gateway protocol parser provided by the embodiments of the present disclosure sends a firmware download request to the IoT cloud platform, it first sends a firmware query request to the IoT cloud platform to request to query whether the protocol data packets stored on the platform side include a new version of the gateway protocol parser, and then receives the firmware query response sent by the IoT cloud platform. When the current version information indicates that the protocol data packets stored on the platform side include a new version of the gateway protocol parser, the gateway protocol parser constructs a firmware download request and sends it to the IoT cloud platform to download the protocol data packets, receives and saves the firmware download response, and then dynamically loads the gateway protocol parser based on the new version of the gateway protocol parser and performs a hot update of the gateway protocol parser. The gateway protocol parser provided by the embodiments of the present disclosure, through information interaction with the IoT cloud platform, can real-time learn about the version update situation of the gateway protocol parser on the platform side, and after determining that there is a version update, obtains the protocol data packets including the new version of the gateway protocol parser and the sub-device model information file supported by it, so as to perform local dynamic loading and hot update based on the protocol data packets. In this way, the embodiments of the present disclosure allow the gateway device to dynamically load or perform a hot update according to the device access requirements without restarting the device or the application program, without the need for a whole machine version iteration, and shorten the time for maintenance personnel to perform device upgrades and related configurations, improving the efficiency of product function iteration.

[0067] It should be noted that in the case where the current version information indicates that the stored protocol data packets do not include a new version of the gateway protocol parser, the gateway protocol parser does not perform any operations.

[0068] Combined with Figure 4 As shown, the embodiments of the present disclosure also provide an access method for IoT sub-devices, including:

[0069] S21, the gateway protocol parser sends a firmware download request to the IoT cloud platform to request to download the protocol data packets, and the protocol data packets include a new version of the gateway protocol parser and the sub-device model information file supported by the gateway protocol parser.

[0070] S22, the gateway protocol parser receives and saves the firmware download response sent by the IoT platform, and the firmware download response includes the protocol data packets.

[0071] S23, the gateway protocol parser dynamically loads the gateway protocol parser based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file to implement a hot update of the gateway protocol parser.

[0072] S24, after the hot update of the gateway protocol parser is successful, the gateway protocol parser receives the model list query request sent by the gateway main service and converts the updated sub-device model information into model list protocol data.

[0073] In this step, after the gateway protocol parser is successfully hot-updated, it further includes: the gateway protocol parser receives an initialization instruction sent by the gateway main service, and performs an initialization operation based on the initialization instruction, so that after the initialization operation of the gateway protocol parser is completed, it receives a model list query request sent by the gateway main service.

[0074] S25. The gateway protocol parser sends model list protocol data to the gateway main service, so that the gateway main service determines whether the sub-device list of the gateway host terminal matches the sub-device list corresponding to the model list protocol data.

[0075] S26. The gateway protocol parser receives the sub-device model configuration information sent by the gateway main service and converts it into configuration list protocol data. The sub-device model configuration information is parsed from the model list protocol data after the gateway main service determines that the sub-device list of the gateway host terminal does not match the sub-device list corresponding to the model list protocol data.

[0076] S27. The gateway protocol parser sends the configuration list protocol data to the gateway main service to synchronize the sub-device model information between the gateway protocol parser and the gateway host terminal.

[0077] Using the access method for IoT sub-devices provided by the embodiments of the present disclosure, after the gateway protocol parser provided by the embodiments of the present disclosure sends a firmware download request to the IoT platform to request the download of protocol data packets, it receives the firmware download response sent by the IoT platform and saves it. The gateway protocol parser dynamically loads the gateway protocol parser based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file carried in the protocol data packet, thereby realizing the hot update of the gateway protocol parser.

[0078] Since the device models or functions supported by different gateway protocol parsers configured for the same gateway device may be different, after the hot update is completed, the gateway protocol parser and the gateway host terminal need to perform a sub-device model information synchronization operation. Specifically, after the gateway protocol parser is successfully hot-updated, it first receives a model list query request sent by the gateway main service, converts the updated sub-device model information into model list protocol data, and then sends it to the gateway main service to enable it to determine whether the sub-device list of the gateway host terminal matches the sub-device list corresponding to the model list protocol data. After the gateway protocol parser receives the sub-device model configuration information sent by the gateway main service and converts it into configuration list protocol data, it sends the configuration list protocol data to the gateway main service, thereby realizing the synchronization of the sub-device model information between the gateway protocol parser and the gateway host terminal under the coordination of the gateway main service.

[0079] Combined with Figure 5 As shown, the embodiments of the present disclosure also provide an access method for IoT sub-devices, including:

[0080] S31. When the gateway main service determines that the hot update of the gateway protocol parser is successful, it sends a model list query request to the gateway protocol parser.

[0081] S32. The gateway main service receives the model list protocol data sent by the gateway protocol parser. Among them, the model list protocol data is generated by the gateway protocol parser through conversion of the updated sub-device model information.

[0082] S33. When the gateway main service determines that the gateway host side does not fully support the sub-device list corresponding to the model list protocol data, it obtains the sub-device model configuration information based on the model list protocol data.

[0083] S34. The gateway main service distributes the sub-device model configuration information to the gateway host side to synchronize the sub-device model information between the gateway protocol parser and the gateway host side.

[0084] Using the access method for IoT sub-devices provided in the embodiments of the present disclosure, since the device models or device functions supported by different gateway protocol parsers configured for the same gateway device may be different, after the hot update, the gateway protocol parser and the gateway host side need to perform a sub-device model information synchronization operation. When the gateway main service determines that the hot update of the gateway protocol parser is successful, it sends a model list query request to it and receives the model list protocol data sent by the gateway protocol parser. When it is determined that the gateway host side does not fully support the sub-device list corresponding to the model list protocol data, the sub-device model configuration information is obtained based on the model list protocol data and distributed to the gateway host side to realize the synchronization of the sub-device model information between the gateway protocol parser and the gateway host side.

[0085] Optionally, the gateway main service determines that the gateway host side does not fully support the sub-device list corresponding to the model list protocol data, including:

[0086] The gateway main service sends a configuration query request to the gateway host side to enable the gateway host side to determine whether the gateway host side fully supports the sub-device list corresponding to the model list protocol data. The configuration query request includes the model list protocol data.

[0087] The gateway main service receives the configuration query response sent by the gateway host side.

[0088] In the case where the configuration query response indicates incomplete support, the gateway main service determines that the gateway host side does not fully support the sub-device list corresponding to the model list protocol data.

[0089] In a specific embodiment, the gateway host side determines whether the gateway host side fully supports the sub-device list corresponding to the model list protocol data, including:

[0090] When the gateway host determines that the sub-device list corresponding to the protocol data of the gateway host sub-device list and the model list is the same, it determines full support; or,

[0091] When the gateway host determines that the sub-device list corresponding to the protocol data of the gateway host sub-device list and the model list is different, it determines that it does not fully support.

[0092] Combined with Figure 6 As shown, the embodiments of the present disclosure also provide an access method for Internet of Things sub-devices, including:

[0093] S41, the Internet of Things cloud platform receives a firmware download request sent by the gateway protocol parser. The firmware download request is used to request the download of a protocol data packet, and the protocol data packet includes a new version of the gateway protocol parser and a sub-device model information file supported by the gateway protocol parser.

[0094] S42, the Internet of Things cloud platform sends a firmware download response to the gateway protocol parser so that the gateway protocol parser dynamically loads the gateway protocol parser based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file. The firmware download response includes the protocol data packet.

[0095] By using the access method for Internet of Things sub-devices provided by the embodiments of the present disclosure, the Internet of Things cloud platform provided by the embodiments of the present disclosure receives the firmware download request sent by the gateway protocol parser, and sends a firmware download response to it so that it dynamically loads based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file, realizing the hot update of the gateway protocol parser. When there is a need for a new model of Internet of Things sub-devices to access the network, the embodiments of the present disclosure realize the iteration of the separate version of the new model of Internet of Things sub-devices through the information interaction between the Internet of Things cloud platform and the gateway protocol parser, without relying on the release of the whole machine version, which is beneficial to improving the efficiency of product function iteration and realizing the rapid iteration of product functions.

[0096] Combined with Figure 7 As shown, the embodiments of the present disclosure also provide an access method for Internet of Things sub-devices, including:

[0097] S51, the Internet of Things cloud platform receives a firmware query request sent by the gateway protocol parser. The firmware query request is used to request to query whether the stored protocol data packet includes a new version of the gateway protocol parser.

[0098] S52, the Internet of Things cloud platform sends a firmware query response to the gateway protocol parser. The firmware query response includes the current version information of the stored protocol data packet, so that the gateway protocol parser determines to construct a firmware download request when the stored protocol data packet is a new version data packet.

[0099] S53. The Internet of Things cloud platform receives a firmware download request sent by a gateway protocol parser. The firmware download request is used to request the download of protocol data packets, and the protocol data packets include a new version of the gateway protocol parser and a sub-device model information file supported by the gateway protocol parser.

[0100] S54. The Internet of Things cloud platform sends a firmware download response to the gateway protocol parser so that the gateway protocol parser dynamically loads the gateway protocol parser based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file. The firmware download response includes protocol data packets.

[0101] By using the access method for Internet of Things sub-devices provided in the embodiments of the present disclosure, after the Internet of Things cloud platform receives a firmware query request sent by a gateway protocol parser, it sends a firmware query response to the gateway protocol parser. The Internet of Things platform then receives a firmware download request sent by the gateway protocol parser and sends a firmware download response to it so that the gateway protocol parser dynamically loads the gateway protocol parser based on the new version of the gateway protocol parser and updates the sub-device model information according to the sub-device model information file. When there is a new model of Internet of Things sub-device with a need to access the network, through the interaction between the Internet of Things platform and the gateway protocol parser in the embodiments of the present disclosure, the iteration of a separate version of the new model of Internet of Things sub-device can be achieved without the need for a whole machine version release, which is beneficial to improving the efficiency of product function iteration and realizing the rapid iteration of product functions.

[0102] Optionally, the Internet of Things cloud platform obtains the protocol data packets in the following manner:

[0103] The Internet of Things cloud platform obtains the protocol data packets from the gateway protocol parser code repository. Among them, the protocol data packets are created and generated by developers based on product requirements to develop functional codes and using a pipeline;

[0104] The Internet of Things cloud platform copies the protocol data packets from the gateway protocol parser code repository to the local storage of the platform.

[0105] In this way, when a new model device has an access requirement, developers develop functional codes based on product requirements, create and generate protocol data packets using a pipeline, and save them to the gateway protocol parser code repository. The Internet of Things platform copies the protocol data packets to the local storage to retrieve the protocol data packets from the gateway protocol parser code repository.

[0106] Optionally, the developer develops functional code based on product requirements and uses a pipeline to create and generate protocol data packets, including: the developer creates a new version of the gateway protocol parser and pipeline configuration information based on the application configuration; the developer builds and generates protocol data packets in the cloud according to the pipeline configuration information for the Internet of Things and the platform to perform data copy operations. Among them, the product requirements include the application configuration, and the application configuration corresponds to the functional code.

[0111] S64, the gateway host receives the sub-device model configuration information sent by the gateway main service, and the sub-device model configuration information is obtained by the gateway main service based on the model list protocol data when the configuration query response indicates not fully supported.

[0112] Using the access method for Internet of Things sub-devices provided by the embodiments of the present disclosure, after the gateway host receives the configuration query request, it determines whether the gateway host fully supports the list of sub-devices corresponding to the model list protocol data and then sends a configuration query response to the gateway main service. After that, the gateway host receives the sub-device model configuration information to synchronize the sub-device model information between the gateway host and the gateway protocol parser.

[0113] Optionally, after the gateway host receives the sub-device model configuration information sent by the gateway main service, it further includes:

[0114] After determining that the sub-device model configuration information is received, the gateway host updates the list of sub-devices of the gateway host based on the sub-device model configuration information.

[0115] In the case where the synchronous update is completed, the gateway host sends a synchronous configuration confirmation response to the gateway main service.

[0116] In this way, after the gateway host determines that the synchronization of the sub-device model information with the gateway protocol parser is completed, it notifies the gateway main service in a timely manner.

[0122] S104, The gateway protocol parser sends a firmware download request to the IOT cloud platform.

[0123] S105, The IOT cloud platform sends a firmware download response to the gateway protocol parser. The firmware download response includes protocol data packets.

[0124] S106, The gateway protocol parser saves the protocol data packets for hot update.

[0125] S107, After the hot update of the gateway protocol parser is completed, it sends a successful update message to the gateway main service.

[0126] S108, The gateway main service releases the resources of the dynamic library of the current firmware, and then dynamically loads the dynamic library of the gateway protocol parser.

[0127] S109, The gateway main service sends an initialization instruction to the gateway protocol parser.

[0128] S110, The gateway protocol parser performs an initialization operation based on the initialization instruction.

[0129] S111, The gateway main service sends a model list query request to the gateway protocol parser.

[0130] S112, The gateway protocol parser converts the updated zigbee model information based on the zigbee protocol into model list protocol data.

[0131] S113, The gateway protocol parser sends the model list protocol data to the gateway main service.

[0132] S114, When the gateway main service determines that the zigbee device list corresponding to the model list protocol data is not fully supported by the zigbee host side, it obtains the zigbee model configuration information based on the model list protocol data.

[0133] S115, The gateway main service distributes the zigbee model configuration information to the Zigbee Host.

[0134] S116, When the Zigbee Host finishes the synchronization update, it sends a synchronization configuration confirmation response to the gateway main service to synchronize the zigbee model information between the zigbee host side and the gateway protocol parser.
