The cloud platform can only receive the binary data sent by the networked device through the transmission module. Therefore, it is necessary to use a set of algorithms on the cloud platform to try to analyze the protocol stack corresponding to the binary data. Although the cloud platform meets the requirements based on most protocol stacks on the market rules, but it is also necessary to match the protocol stack corresponding to the best binary according to the feature value among many protocol stacks. Specifically, multiple parsing instances are implemented in the learning engine of the cloud platform to continuously use the existing protocol stacks through different combinations. Match the received binary to determine which protocol stack has the highest probability of matching, and it is considered that the received binary file uses this protocol stack. Among them, the algorithms for parsing binary matching existing protocols include: int BinCode, intID, int ControlCode, intAttribute, and int Mode, and the algorithms for receiving binary data include: intBinRecv, int fd, char*data, int datalen, and int**arg. The embodiment does not specifically limit it. Such a cloud platform, on the basis of many known and accumulated protocol stacks, uses its own powerful computing power to reversely analyze the binary protocol stacks, thereby realizing the control of different types of networked devices.

In an optional embodiment, the sending the control information to the transmission module, so that the networked device executes the control information, includes:

Send the control information to the transmission module through the transmission protocol, so that the transmission module converts the control information into a data protocol that the networked device can recognize according to the rules of the protocol stack with the support of the protocol conversion engine, and sends it to the networked device for execution.

The transmission protocol includes: message queue telemetry transmission MQTT protocol or/and limited application COAP protocol, but not limited thereto.

Further, the local terminal includes: a transmission module or a networking device.

The transmission module is also used to send a heartbeat connection to the cloud platform within a specified time interval to ensure that the link between the transmission module and the cloud platform is normal, paving the way for subsequent network data transmission between the cloud platform and the transmission module. Wherein, the predetermined time interval may be 10 minutes, 20 minutes, or 30 minutes, etc., which is not limited in this embodiment.

The transmission module includes: client software stored in the host of the networked device, or an IoT gateway communicatively connected with the networked device. Wherein, when the transmission module is client software, the local terminal is a networking device; when the transmission module is an Internet of Things gateway, the local terminal is an Internet of Things gateway.

Specifically, the client software runs on the host of the networked device, the client software obtains the network data packet sent by the networked device, and obtains the networked device data including the networked device ID, control code and attribute value by analyzing the network data packet . The client software requests to the cloud platform to download the protocol stack belonging to the ID of the networked device. If the protocol stack of the networked device has been supported, the client software will download the protocol stack corresponding to the ID of the networked device to the host of the networked device. During this process, the protocol stack only needs to be downloaded for the first time, and can be used directly later. After the first business system imports the protocol stack, the client software, with the support of the protocol conversion engine, completes the arrangement and analysis of the data of the networked devices, obtains the corresponding functional business information and log information, and transmits them to the The cloud platform stores the functional business information and log information of networked devices on the cloud platform.

If the cloud platform sends control information to the networked device, it is transmitted to the client software through the MQTT protocol or COAP protocol, and the control information is converted into the data protocol of the networked device with the support of the protocol conversion engine according to the rules of the protocol stack and sent to the networked device for execution. .

If the protocol stack of the networked device is not supported, the business system of the client software will monitor the data of the networked device, and transmit the data transmitted by all functions of the networked device to the cloud platform through the MQTT protocol or the COAP protocol. The engine parses the ID, control code and attribute value of the networked device, forms the protocol stack of the networked device at the same time, and notifies the client software to download the protocol stack of the networked device, and then the client software will download the newly generated protocol stack to the networked device. In the host machine of the device, after the first business system imports the protocol stack, the client software completes the collation and analysis of the data of the networked device with the support of the protocol conversion engine, obtains the corresponding functional business information and log information, and passes the MQTT protocol or COAP The protocol is transmitted to the cloud platform, and the functional business and log information of the networked devices are stored on the cloud platform.

The client software runs on the host of the networked device. The client software obtains the network packet data information sent by the networked device, and obtains the networked device data including the networked device ID, control code, and attribute value by analyzing the network packet. When the client software does not import the protocol stack, the protocol conversion engine converts the data packet of the networked device as a whole into MQTT protocol or COAP protocol and transmits it to the cloud platform. Organize and analyze the package, obtain the corresponding functional business information and log information, and store the functional business information and log information of networked devices on the cloud platform.

If the cloud platform does not have a protocol stack corresponding to the networked device, then the cloud platform will notify the business system of the client software to monitor the data of the networked device, monitor the data transmitted by all functions of the networked device, and pass the data through the MQTT protocol or the COAP protocol. Transfer to the cloud platform, use the learning engine of the cloud platform to analyze the ID, control code and attribute value of the networked device, and form the protocol stack of the networked device at the same time, and the cloud platform will process the data uploaded to the cloud platform by the networked device according to the newly generated protocol stack. Organize, analyze, obtain corresponding functional business information and log information, and store functional business information and log information of networked devices on the cloud platform.

The method completes the configuration of the protocol stack through the transmission module, so that different networked devices can be connected to the cloud platform, which not only ensures that each networked device independently provides corresponding services, but also enables the cloud platform to manage and manage different networked devices. control. In addition, through automatic learning to match the corresponding protocol stack for the networked device, it is possible to match the protocol stack with a high similarity to complete the connection between the networked device and the cloud when there is no protocol stack that is completely consistent with the networked device on the cloud platform. Access to the platform; at the same time, when the cloud platform does not have a protocol stack that meets the similarity requirements, the learning engine on the first-level cloud platform can generate a protocol stack that matches the networked device through the attribute information of the networked device. Among them, the learning engine
