Communication method and communication device

Abstract

The present application provides a communication method and a communication device. The communication method includes: a sending device determines a first moment, and the first moment is a moment when a receiving device needs to submit first data to an application layer of the receiving device; The sending end device sends the first indication information and the first data, the first information is used to instruct the receiving end device to submit the first data to the application layer of the receiving end device at the first moment, which can support the receiving end The device determines the first time according to the first indication information, and submits the first data to the application layer at the first time, thereby enabling the receiving device to execute the action corresponding to the first data at the application layer at the first time , therefore, it is possible to avoid the influence of the transmission delay on the action corresponding to the data performed by the receiving end device.

Description

technical field [0001] The present application relates to the field of communication, and more particularly, to a communication method and a communication device. Background technique [0002] At present, there is a known control technology. The receiver device receives an operation instruction (or control information) sent by the sender device, and immediately executes an action indicated by the operation instruction after receiving the control information. In this technology, in order to ensure accurate control of the actions performed by the receiving end, the sending end device needs to know the transmission delay of the control information between the sending end device and the receiving end device, so as to consider the transmission time when designing operation instructions. Delay, so that the receiver device can execute the action indicated by the operation instruction at the expected time. [0003] When wired communication is used between the sending end device and...

Problems solved by technology

[0004] However, the above-mentioned wired communication method needs to arrange cables between the sending end device and the receiving end device. Due to the influence of the terrain of the production site, etc., it may lead to more difficult wiring, which seriously affects the flexibility and cost of equipment layout.

[0005] In this regard, wireless transmission can be considered instead of wired transmission. However, in wireless transmission, due to the instability of the channel, it is difficult to fix the transmission delay between the sending end device and the receiving end device, that is, in At different times, the transmission delay between the sending end device and the receiving end device may change due to factors such as channel quality, which leads to the inability of the sending end device to accurately predict the action execution time of the receiving end device, increasing the delay of operation instructions.
