The following descriptions are made separately:

(1) If communication is required between the intelligent terminal devices under the same sub-gateway device, the data can be directly forwarded after being received and processed by the sub-gateway device, and the destination intelligent terminal device returns a response message after receiving the data packet to complete a transmission. The communication between the intelligent terminal devices under the same sub-gateway device does not need to go through the central data switch and the control center, which reduces the consumption of route addressing and reduces the load on the network. The specific communication steps are as follows:

Step 1: The intelligent terminal device sends data to the sub-gateway device.

Step 2: After receiving the data, the sub-gateway device determines whether the data is from the terminal device under the gateway, and if it proceeds to step 3, otherwise discards the data packet and does not perform transmission. Step 3: The sub-gateway device determines whether the destination intelligent terminal device is under the local gateway, and if yes, forwards the data to the terminal, otherwise forwards to the corresponding sub-gateway device.

Step 4: After receiving the data correctly, the smart terminal device replies with a response message to the source terminal to complete a transmission.

(2) If the terminal equipment under different sub-gateway devices needs to perform data communication, it needs to be forwarded through its sub-gateway device and main gateway device. The specific communication steps are as follows:

Step 1: The smart terminal device sends data to the first sub-gateway device.

Step 2: After receiving the data, the first sub-gateway device determines whether the data is from the terminal device under the gateway, and if it enters step 3, otherwise discards the data packet, and does not perform transmission.

Step 3: The first sub-gateway device processes and encapsulates the data according to a predetermined communication protocol (such as a TCP/IP protocol, and the specific protocol may be determined according to a connection manner with the main gateway device).

Step 4: The encapsulated data packet is sent to the main gateway device via the system bus.

Step 5: The primary gateway device determines, according to the destination address of the data packet, the sub-gateway where the destination intelligent terminal device is located, and sends the data packet to the corresponding second sub-gateway device.

Step 6: After receiving the data packet, the second sub-gateway device performs decapsulation processing, and sends the data to the destination intelligent terminal device through the corresponding radio port of the terminal.

Step 7. The destination intelligent terminal device replies with a response message to the primary gateway device after receiving the data packet.

Step 8. The primary gateway device forwards the response message to the source terminal to complete a transmission.

(3) The intelligent terminal device communicates with the main gateway device, and the data collected by the terminal (temperature, humidity, gas sensor, etc.) is sent to the main gateway device and the main gateway device controls the smart terminal device (control of intelligent lights, curtains, etc.) ). The specific communication steps are as follows:

Step 1: The intelligent terminal device sends data to the sub-gateway device to which it belongs.

Step 2: After receiving the data, the sub-gateway device determines whether the data is from the terminal device under the gateway, and if it proceeds to step 3, otherwise discards the data packet and does not perform transmission.

Step 3: The sub-gateway device processes and encapsulates the data according to a predetermined communication protocol (such as a TCP/IP protocol, and the specific protocol may be determined according to a connection manner with the main gateway device). Step 4: The encapsulated data packet is sent to the main gateway device via the system bus. Step 5: The primary gateway device decapsulates the data packet according to a predetermined protocol.

Step 6. The primary gateway device forwards the response message to the source terminal to complete a transmission.

In summary, according to the above technical solution of the present invention, after receiving the data including the multiple formats from the terminal device, the sub-gateway device performs unified encapsulation processing on the data according to the preset data frame format, and processes the package. The data frame of the unified format is sent out, and the data transmission of multiple data protocols in the smart home Internet of Things system is realized.

The above is only the embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention.
