[0017] Figure 2 It is a structural schematic diagram of an information processing device between an Internet of Things device and a cloud platform in Embodiment 2 of the present invention;

[0018] Figure 3 It is a structural schematic diagram of an electronic device in Embodiment 3 of the present invention. DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0020] In order to solve the problem of IoT devices using non-standard protocols to communicate with cloud platforms, the main existing solutions can be roughly summarized into two categories: IoT device-side adaptation and cloud platform-side adaptation.

[0021] 1. IoT device adaptation: The core idea of ​​this solution is to modify or add code directly on the IoT device so that the device can support the standard protocol required to communicate with the cloud platform. For example, the device may originally use a customized, non-standard protocol. Developers can implement a standard protocol (such as MQTT) on the device so that the device can communicate directly with the cloud platform.

[0022] 2. Cloud platform adaptation: Another solution is to add or modify code directly on the cloud platform so that the cloud platform can support non-standard protocols used by devices. For example, the cloud platform may originally only support the Message Queuing Telemetry Transport (MQTT) protocol, and developers can implement support for non-standard protocols used by devices on the cloud platform.

[0023] IoT device adaptation: Modifying device code requires sufficient development resources and a deep understanding of the internal structure of the device. In addition, if the number of devices is large or the device types are diverse, modifying the code of all devices may take a lot of time and resources. Finally, modifying the device code may affect the stability and security of the device.

[0024] Cloud platform adaptation: First, modifications to the cloud platform may affect the stability and performance of the platform. Second, since there may be many non-standard protocols used by devices, the cloud platform needs to support all of these protocols, which may require a lot of development resources. Finally, modifications to the cloud platform may need to undergo rigorous auditing and testing, which may take a lot of time.

[0025] Embodiment 1

[0026] Figure 1 A flowchart of an information processing method between an IoT device and a cloud platform is provided in Embodiment 1 of the present invention. This embodiment is applicable to information processing between an IoT device and a cloud platform. The method can be executed by an information processing device between the IoT device and the cloud platform. The device can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, which can be a mobile terminal, a PC or a server, etc.

[0027] The solution in this embodiment includes two parts: one is a gateway program developed in Java language based on the Netty framework, and the other is a small device that can run the gateway program.

[0028] The gateway program can receive and parse IoT device messages of non-standard protocols, convert these messages into standard protocols, and finally send these messages to the cloud platform through standard protocols. The configuration of the small device includes the following: (1) Processor: The device can be configured with a quad-core processor to support the Ubuntu operating system and Java runtime environment. The processor can provide sufficient computing power to process the relevant logic of the gateway program. (2) Memory: The small device is configured with 8GB of memory to cache data and programs when the gateway program is running. Such memory capacity is sufficient to run the gateway program and process a large number of device messages. (3) Disk storage: The device uses 64GB eMMC Flash for storage. This storage device is used to store the operating system, gateway program and its related configuration files, log files, etc. In addition, the read and write speed of eMMC Flash is fast, which can meet the data reading and writing requirements of the gateway program. (4) Network interface: The small device has an Ethernet interface and can be connected to the network via a wired method. At the same time, the device also supports wireless connection methods such as Wi-Fi and Bluetooth, allowing the device to run in a wireless environment. (5) Operating system: The device runs the Ubuntu operating system based on the ARM architecture. Ubuntu is an open source Linux distribution with rich software support and can run Java programs. (6) Power supply: The device is powered by a 5V / 3A power adapter. The power supply can provide stable voltage and current to ensure the normal operation of the device. (7) Dimensions: The size of the small device is designed to be 120mm*90mm*40mm, which is convenient for deployment in various environments. (8) Environmental requirements: The small device can operate in an ambient temperature of -20℃ to 60℃, meeting the operating requirements of most environments.

[0029] like Figure 1 As shown, the method specifically comprises the following steps:

[0030] S110, establishing a connection with the IoT device and determining the communication protocol adopted by the IoT device to obtain the original protocol.

[0031] In this embodiment, the IoT device is connected to the small device through an adapter of the corresponding protocol (such as a wireless network card, a wired network card, Bluetooth, a serial port, etc.). The original protocol can be MQTT, Modbus, Bluetooth Low Energy (BLE), Controller Area Network (CAN), Extensible Messaging and Presence Protocol (XMPP), Open Charge Point Protocol (OCPP), Socket.

[0032] Optionally, the method of establishing a connection with an IoT device and determining the communication protocol adopted by the IoT device may be: receiving a connection request sent by the IoT device; establishing a network connection with the network device based on a network address; authenticating the IoT device based on authentication information to obtain an authentication result; if the authentication result is passed, determining the communication protocol adopted by the IoT device based on the device identification.

[0033] The connection request includes authentication information, network address and device identification. In this embodiment, the connection process involves steps such as device identification, network connection, protocol identification, and device authentication.

[0034] For device identification: When the IoT device tries to establish a connection, the small device must first perform a device identification process. The identification process may include but is not limited to obtaining basic information such as the device MAC address, IP address, and device model, which can help the small device identify the type of IoT device it is trying to access. For network connection: The IoT device will then establish a stable network connection with the small device. The connection can be through a wired network, a wireless network, Bluetooth, CAN, Modbus, etc. This process may involve the configuration of network parameters, including but not limited to IP address, subnet mask, default gateway, etc. For device authentication: In order to ensure the legitimacy of the IoT device, the small device needs to authenticate the IoT device. This process may include but is not limited to: password authentication, digital certificate authentication, hardware ID matching, and other methods. Only devices that have successfully authenticated can further communicate with the small device. For protocol identification: After the IoT device successfully accesses the network and passes the authentication, the small device needs to identify the specific communication protocol used by the device. This process can be completed based on the device's initial handshake information, the device's model information, and the device's pre-registered protocol information.

[0035] Through the above steps, the IoT device successfully established a stable and secure network connection with the small device, and obtained the communication protocol of the IoT device, laying the foundation for subsequent message reception and parsing.

[0036] S120, receiving first original information sent by the IoT device, and parsing the first original information based on an original protocol to obtain first parsed data.

[0037] Optionally, a first original information sent by an IoT device is received, and the first original information is parsed based on an original protocol to obtain first parsed data in the following manner: verifying the integrity and / or consistency of the first original information; if the verification passes, decoding the first original information; parsing the decoded first original information based on the original protocol to obtain first parsed data; and formatting the first parsed data according to a preset format conversion rule to obtain first parsed data after the format conversion.

[0038] In this embodiment, after establishing a connection with an IoT device, its message will be received and parsed. The specific process includes: message reception, message decoding, message parsing, and data format conversion.

[0039] For message reception: After the IoT device successfully establishes a network connection, the gateway program starts to receive messages. These messages may include device status updates, data transmission, command responses, etc. The gateway program will perform preliminary checks on the received messages, such as checking the integrity and consistency of the messages, and then store them in its internal buffer. For message decoding: The received messages are generally encoded, including but not limited to BASE64, hexadecimal encoding (HEX) and other encoding methods. Therefore, the gateway program needs to decode the received messages. This process requires the gateway program to determine and be able to handle the specific encoding method used by the IoT device. For message parsing: After the message decoding is completed, the gateway program needs to parse the message according to the communication protocol used by the device. This process involves splitting the message according to the format and structure specified by the protocol, and extracting the various parts of the message, such as commands, parameters, data, etc. For data format conversion: In the process of message parsing, some data format conversion operations are involved. For example, some data needs to be converted from binary to decimal, or some text data needs to be converted from one character encoding (such as GBK) to another character encoding (such as UTF-8). Through the above steps, the gateway program receives and parses the messages sent by the IoT devices and obtains data that can be further processed. This provides the necessary input information for subsequent protocol conversion and message sending.

[0040] S130, performing protocol conversion on the first parsed data to obtain first target information.

[0041] The first target information is encapsulated by a target protocol. Exemplarily, the target protocol may be the MQTT protocol.

[0042] Optionally, the first parsed data may be subjected to protocol conversion to obtain the first target information by: obtaining a data structure mapping relationship between the original protocol and the target protocol; converting the data structure of the first parsed data based on the data structure mapping relationship; and assembling the first parsed data after the data structure conversion according to the target protocol to obtain the first target information.

[0043] In this embodiment, after receiving and parsing the message, the parsed data needs to be converted into a protocol supported by the cloud platform. This process mainly includes two steps: message mapping and message construction.

[0044] For message mapping: When the message of the original protocol is parsed, the gateway program needs to map the parsed data to the message format of the target protocol. This involves the conversion of data types, data structures, commands, etc., in order to comply with the protocol specifications of the cloud platform. For message construction: According to the target protocol, the gateway program needs to construct a new message of the target protocol. For example, assuming that the target protocol is the MQTT protocol, the constructed message includes the following main parts: (1) Fixed header: This part includes the message type (such as CONNECT, PUBLISH, SUBSCRIBE, etc.), the quality level of the message (QoS level), reserved bits and remaining length, etc. (2) Variable header: The content of this part depends on the message type of the fixed header. For example, for the PUBLISH message, the variable header contains the topic name and the message identifier. (3) Payload: This part contains the actual application message. Its content depends on the message type of the fixed header and the specific content of the variable header. Through the above steps, the gateway program successfully converts the message of the original protocol into the message of the target protocol, providing a basis for sending subsequent messages to the cloud platform.

[0045] S140, establishing a connection with the cloud platform, and sending the first target information to the cloud platform for processing.

[0046] In this embodiment, after constructing the message of the target protocol, the message needs to be sent to the cloud platform. If it is the first time to send, it is necessary to establish a connection with the cloud platform first. Optionally, the way to establish a connection with the cloud platform can be: obtaining connection-related information of the cloud platform; establishing a connection with the cloud platform based on the connection-related information; negotiating a connection with the cloud platform to obtain a negotiation result; if the negotiation result is a successful negotiation, periodically sending heartbeat information to the cloud platform to maintain the connection with the cloud platform.

[0047] The connection related information includes: network address, port information, authentication information. In this embodiment, the connection process with the cloud platform mainly includes the following steps: cloud platform information configuration, connection establishment, connection negotiation, and connection maintenance.

[0048] Specifically, for cloud platform information configuration: In order to connect to a specific cloud platform, the gateway program needs to pre-configure relevant information about the cloud platform, including the address of the cloud platform (such as URL or IP address), port, and related authentication information (such as username and password, or digital certificate). For connection establishment: The gateway program uses the pre-configured information to try to establish a connection with the cloud platform. This process may involve multiple network protocols, such as TCP / IP, SSL / TLS, etc., as well as possible authentication processes. If the connection establishment fails, the gateway program needs to be able to handle the corresponding errors and try to re-establish the connection. For connection negotiation: Once the network connection is established, the gateway program needs to negotiate the connection of the target protocol. This includes sending a CONNECT message to the cloud platform and receiving a CONNACK message from the cloud platform. If the negotiation fails, for example, because the CONNACK message returned by the cloud platform indicates that the connection is rejected, the gateway program needs to be able to handle the corresponding errors. For connection maintenance: After the connection is established and the connection negotiation is successful, the gateway program needs to maintain the active state of the connection. This includes sending MQTT's PINGREQ and PINGREESP messages to detect the active state of the connection, and handling corresponding network problems and errors. Through the above steps, the gateway program successfully establishes a connection with the cloud platform and is ready to send the converted MQTT message.

[0049] Optionally, the first target information may be sent to the cloud platform for processing by: writing the first target information into a queue according to priority; reading the first target information from the queue according to priority; and sending the read first target information to the cloud platform for processing.

[0050] In this embodiment, sending the first target information to the cloud platform for processing mainly includes the following steps: message queuing and management, message sending, sending confirmation processing, error and exception handling.

[0051] Specifically, for message queuing and management: After the messages of IoT devices are converted into messages of the target protocol, these messages will be added to Netty's event loop. Netty's event loop is responsible for managing all messages to be sent, including sorting them according to their priority and handling possible network delays so that messages can be sent when the network is available. For message sending: When the event loop is ready for I / O operations, Netty extracts MQTT messages from the queue of messages to be sent, encodes them into bytes using the encoder of its processing pipeline, and then sends them to the established connection. This process can handle the sending of messages at various QoS levels. For sending confirmation processing: In Netty's processing pipeline, once the sending is completed and the confirmation message is received from the cloud platform, a new event will be triggered, and the processor with this event is responsible for processing these confirmation messages. For example, if the QoS level of an MQTT message is 1 or 2, after receiving the PUBACK, PUBREC, or PUBCOMP message from the cloud platform, the corresponding processor needs to remove the message from the queue to be sent. For error and exception handling: The Netty framework provides a processing mechanism for network errors and exceptions. If errors or exceptions are encountered during the message sending process, such as network interruption or message timeout, Netty's processing pipeline can capture these exceptions and then handle them through the configured exception handler, such as re-establishing the connection, resending the message, recording the error log, etc. In this embodiment, with the help of the Netty framework, the network management program can effectively send the messages received from the IoT device to the cloud platform for processing.

[0052] Optionally, after sending the first target information to the cloud platform for processing, the following steps are also included: receiving second original information sent by the cloud platform; performing protocol conversion on the second original information to obtain second target information; sending the second target information to the Internet of Things device, so that the Internet of Things device executes the operation corresponding to the second target information.

[0053] The second original information is encapsulated by the target protocol; the second target information is encapsulated by the original protocol. In this embodiment, receiving the message sent by the cloud platform mainly includes the following steps: message queuing and management, confirmation processing of message reception, and error and exception processing.

[0054] Specifically, for message queuing and management, after receiving the second original information sent by the cloud platform, these messages will be added to Netty's event loop. Netty's event loop is responsible for managing all messages to be sent and handling possible network delays so that messages can be sent when the network is available. For confirmation processing of message reception: For messages that require feedback to the cloud platform (such as messages with QoS level 1 or 2), the Netty message processor will create a corresponding confirmation message and then add it to the message queue to be sent, waiting for Netty's event loop to send it. For error and exception handling: The Netty framework provides a processing mechanism for network errors and exceptions. If errors or exceptions are encountered during message sending, such as network interruption or message timeout, Netty's processing pipeline can capture these exceptions and then handle them through the configured exception handler, such as re-establishing the connection, resending the message, and recording the error log.

[0055] Optionally, the second original information is subjected to protocol conversion, and the method for obtaining the second target information may be: decoding the second original information; parsing the decoded second original information based on the target protocol to obtain second parsed data; obtaining the data structure mapping relationship between the original protocol and the target protocol; converting the data structure of the second parsed data based on the data structure mapping relationship; encapsulating the second parsed data after the data structure conversion to obtain the second target information.

[0056] In this embodiment, the protocol conversion of the second original information mainly includes the following steps: message parsing, protocol mapping search, data conversion, and device instruction generation.

[0057] Specifically, for message parsing: when receiving a message of the target protocol from the cloud platform, the gateway program will decode it into a data format that can be processed by the program, and then process it according to its message type. For example, if it is a PUBLISH type message, its subject name and payload will be parsed, and then related operations will be performed. For protocol mapping search: for each received message of the target protocol, the gateway program will find the corresponding non-standard protocol in the protocol mapping table based on the context information of the current connection. The protocol mapping table contains the mapping relationship from the target protocol to the original protocol of a certain device. For data conversion: based on the mapping relationship found, the gateway program converts the data content of the message of the target protocol into the original protocol format. This may require operations such as encoding, formatting or reordering the data. For device instruction generation: the converted non-standard protocol is encapsulated into device instructions, which may contain information such as device address, function code and data content, and can be recognized and executed by the device. After the above steps, the gateway program converts the message received from the cloud platform into the device instruction of the original protocol that the device can understand.

[0058] Optionally, the process of sending the second target information to the IoT device may be: constructing a data packet based on the second target information and determining a communication interface; and sending the data packet to the IoT device through the communication interface.

[0059] In this embodiment, sending the second target information to the IoT device mainly includes the following steps: data packet creation, communication interface selection, data transmission, transmission confirmation, error and exception handling.

[0060] Specifically, for data packet creation: create a device data packet according to the device instructions generated above. This data packet is usually created according to the specifications of the non-standard protocol and may contain information such as the device address, function code, data length, data content and checksum. For communication interface selection: the gateway program selects the corresponding communication module according to the communication interface of the IoT device (such as Ethernet, Bluetooth, CAN, etc.). For data transmission: the gateway program sends the device data packet to the IoT device through the selected communication module. The transmission process may involve operations such as data packaging, physical layer encoding and transmission. For transmission confirmation: for non-standard protocols that require confirmation, the gateway program will wait for the confirmation message of the IoT device. If the confirmation message is not received within the specified time, the gateway program will try to resend the data packet. For error and exception handling: if there is an exception such as a communication module failure, a physical connection disconnection, or no response from the device, the gateway program will capture it and perform appropriate processing, such as resending, recording an error log, or sending an error report to the cloud platform. After the above steps, the gateway program can send the cloud platform's message to the IoT device in the form of a non-standard protocol, so that the device can receive and execute the corresponding instructions.

[0061] This embodiment has the following advantages: (1) Compatibility: The method and apparatus of this patent can convert the messages of IoT devices with non-standard protocols into the standard MQTT protocol and then forward them to the MQTT cloud platform. This solves the problem in the prior art that IoT devices using non-standard protocols cannot be seamlessly integrated with the cloud platform, and significantly improves the compatibility of IoT devices with the cloud platform. (2) Flexibility: By running a gateway program on a small device, it is possible to access various IoT devices with non-standard protocols, and it can be flexibly deployed at any required location in the device network. Regardless of whether the IoT device uses a wired or wireless connection, it can be connected to the cloud platform through a small device, which greatly enhances the flexibility of the system. (3) Low cost: Compared with existing technical solutions, such as modifying the IoT device code or modifying the cloud platform code, the method and apparatus provided by this patent can eliminate the need for large-scale transformation of existing IoT devices and cloud platforms, greatly reducing the complexity and cost of system integration. (4) High performance: Through a small device with a higher configuration, the gateway program can be better run, larger-scale IoT device data can be processed, and higher performance requirements can be met. (5) Openness: Small devices can run the open source Ubuntu operating system, which is more open and customizable, making it easier to optimize the system and expand its functionality.

[0062] The technical solution of this embodiment is to establish a connection with an IoT device and determine the communication protocol adopted by the IoT device to obtain the original protocol; receive the first original information sent by the IoT device, and parse the first original information based on the original protocol to obtain the first parsed data; perform protocol conversion on the first parsed data to obtain the first target information; wherein the first target information is encapsulated by the target protocol; establish a connection with a cloud platform, and send the first target information to the cloud platform for processing. The information processing method between the IoT device and the cloud platform provided in the embodiment of the present invention is to realize the information interaction between the IoT device and the cloud platform, and ensure the effective connection and secure interaction between the IoT device and the cloud platform.
