Embodiment 1

[0030] A method for guaranteeing multi-channel transmission provided according to the present invention includes:

[0031] Step M1: using the sender to preprocess the data packet to obtain the preprocessed data packet;

[0032] Step M2: Utilize the sending end to send the preprocessed data packet to the receiving end through the channel, and wait for the receiving end to respond at the same time;

[0033] Step M3: The sending end receives a response from the receiving end through the current channel within the preset time, parses the data packet, determines that the sending is successful, and ends the data sending; the sending end does not receive a response from the receiving end through the current channel within the preset time , it is determined that the sending has failed; when the sending end fails to send through the channel, select a channel other than the current channel and repeat steps M2 to M3 until the sending is successful or the number of sending times reaches t...

Embodiment 2

[0045] Embodiment 2 is a modification of embodiment 1

[0046] 1) The sending end sends a data packet to the receiving end through channel 1 (TCP), and the receiving end will reply a response data packet to the sending end after receiving the data packet

[0047] 2) The sender waits for the response packet from the receiver through channel 1 (TCP)

[0048] 3) If the sending end does not receive the response data packet, the sending end will send the data packet to the receiving end through channel 2 (UDP), and the receiving end will reply to the sending end with a response data packet after receiving the data packet; otherwise, the sending end will end Send data this time.

[0049] 4) The sending end sends a data packet to the receiving end through channel 2 (UDP), and the receiving end will reply a response data packet to the sending end after receiving the data packet

[0050] 5) The sender waits for the response packet from the receiver through channel 2 (UDP)

[0051] 6...

Abstract

The invention provides a multichannel transmission guarantee method and system, and the method comprises the steps: M1, carrying out the preprocessing of a data package through a transmitting end, andobtaining a preprocessed data package; M2, sending the preprocessed data packet to a receiving end through a channel by using a sending end, and waiting for response of the receiving end; and M3, enabling the sending end to receive the response of the receiving end through the current channel within the preset time, carrying out corresponding processing on the data packet, judging that the sending is successful after the data packet passes the processing, and ending the data sending, if the sending end does not receive the response of the receiving end through the current channel within the preset time, judging that the sending fails, and after the sending end fails to send through the channel, selecting the channels except the current channel to continue to execute the steps M2 to M3 until the sending is successful or the sending frequency reaches the preset frequency. According to the invention, stable and reliable communication of data between the equipment and the platform is ensured through the bidirectional response model in the protocol.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things communication, in particular, to a multi-channel transmission guarantee method and system. Background technique [0002] Current IoT industry deficiencies: [0003] 1. The communication quality and stability of the mobile wireless communication network are lower than those of the wired network; [0004] 2. Under the mobile wireless communication network, single-channel application scenarios with high requirements for data transmission (real-time, low delay) are too single, and there is no multi-channel cold backup; [0005] 3. Under the mobile wireless communication network, the fluctuation of network quality has obvious tide phenomenon; [0006] Patent document CN106790590A discloses a cloud platform-based IoT terminal communication control system, including: IoT cloud platform, including control terminal binding, control terminal command forwarding, user client authenticatio...
