Problems solved by technology

Due to the different data formats defined by different protocols, the methods of parsing data packets are also different. The more protocols supported by the multi-protocol gateway, the more complex the application layer needs to parse the data format.
Supporting multiple protocols increases the computational complexity of the gateway application layer and increases the difficulty of development

Embodiment 1

[0039] as attached figure 1 Shown, a kind of multi-protocol communication method comprises the following steps:

[0040] Receiving first data packets in different protocol data formats; converting the first data packets in different protocol data formats into second data packets in a custom data format; wherein the custom data format includes a source address segment and a source protocol type segment , target address segment, target protocol type segment, instruction type segment, data length segment and data content segment;

[0041] extracting the target address segment, the target protocol type segment, the instruction type segment and the data content segment in the second data packet of the custom data format;

[0042] If the extracted command type segment is a non-empty field, then confirm the content of the control command through the command type segment, and filter out the pre-stored IoT devices that are consistent with the protocol type corresponding to the target ...

Embodiment 2

[0061] as attached figure 2 As shown, the difference between this embodiment and embodiment 1 is:

[0062] When the target device is the control terminal (the sender is the IoT device), also execute:

[0063] Read the IoT device status value corresponding to the data content segment in the second data packet, and compare the IoT device status value with a preset alarm range;

[0064] If the state value of the IoT device exceeds the preset alarm range, generate a self-regulating instruction, confirm the self-regulating target device based on the self-regulating command, and screen out an interface that is consistent with the protocol type supported by the self-regulating target device The transceiver module is used as a self-adjusting target device interface module;

[0065] When the self-regulating target device interface module and the self-regulating target device are successfully networked, the self-regulating command is encapsulated according to the protocol data format...

Embodiment 3

[0071] as attached image 3 As shown, the difference between this embodiment and the above embodiments is that: when the target device is a control terminal (the sender is an IoT device), it also executes:

[0072] Read the IoT device status value corresponding to the data content segment in the second data packet, and compare the IoT device status value with a preset abnormal range;

[0073] If the state value of the IoT device exceeds the preset abnormal range, it will be determined that the detection result of the corresponding IoT device is abnormal, and the transmission priority of the data packet to be sent corresponding to the IoT device will be modified to the first priority;

[0074] If the status value of the IoT device does not exceed the preset abnormal range, the data packet to be sent is transmitted according to a normal process.

[0075] It can be understood that if the target device is not a control terminal (the sender is not an IoT device), the data packet t...

Abstract

The invention provides a multi-protocol communication method, a smart home gateway and a multi-protocol communication system. The method comprises the the steps of receiving first data packets of different protocol data formats; converting the first data packets of different protocol data formats into second data packets of a self-defined data format; extracting a target address segment, a targetprotocol type segment, an instruction type segment and a data content segment in the second data packet with the self-defined data format; and if the extracted instruction type segment is a non-emptyfield, determining the content of the control instruction through the instruction type segment, screening out pre-stored Internet of Things devices and the like consistent with the protocol type corresponding to the target protocol type segment, and if the number of the screened Internet of Things devices is equal to 1, directly taking the corresponding Internet of Things device as a target deviceand the like. According to the invention, while the compatibility and universality of the gateway are improved, the design and development difficulty of a gateway application layer is reduced, the multi-protocol communication efficiency is improved, and the operation cost of the multi-protocol gateway is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular, to a multi-protocol communication method, a smart home gateway and a multi-protocol communication system. Background technique [0002] In recent years, driven by the Internet of Things technology, the smart home industry has developed rapidly, and more and more smart home devices with different functions have appeared. In a basic smart home system, the home gateway is the main hub of the system, connecting smart home devices internally for data aggregation and forwarding; connecting externally with control terminals to support users' remote control and management of home devices. At present, there are two ways of communication between smart home devices and smart home gateways: wired and wireless. Although the signal of wired communication is stable, it has the disadvantages of difficult wiring and high cost. With the vigorous development of wireless communication technolo...
