Communication method and communication device

Abstract

The invention provides a communication method and a communication device. The communication method comprises the following steps: sending end equipment determines a first moment, wherein the first moment is a moment when receiving end equipment needs to submit first data to an application layer of the receiving end equipment; and the sending end equipment sends first indication information and thefirst data, wherein the first information is used for indicating that the receiving end equipment submits the first data to the application layer of the receiving end equipment at the first moment. The receiving end equipment can be supported to determine the first moment according to the first indication information, and submits the first data to the application layer at the first moment, so that the receiving end equipment can be supported to execute an action corresponding to the first data at the application layer at the first moment; and therefore, the influence of transmission time delay on operation of executing the action corresponding to the data by the receiving end equipment can be avoided.

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.
