Abstract

The invention relates to the communication field, in particular to a communication method, which includes the following steps: 1) the input processing device inputs instruction information and data information and packages the instruction information and data information into a communication data frame and transmits the data frame into a display processing device; 2) the display processing device receives and un-packages the communication data frame; and 3) the display processing device verifies the integrity of the un-packaged communication data frame, takes out the instruction information and data information in the communication data frame, analyzes the instruction information and data information, and displays the analysis result on the display processing position if the communication data frame is integral, and casts the communication data frame off if the communication data frame is non-integral. The communication method can solve the problems of the prior art that the transmitting safety is low, the efficiency is low, the secondary development of the equipment is difficult, the developing efficiency is low, and the developing cost is high.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication method. Background technique [0002] For point-to-point communication, according to the direction and time relationship of message transmission, the communication methods can be divided into three types: simplex communication, half-duplex communication and full-duplex communication. [0003] Simplex communication refers to the working mode in which messages can only be transmitted in one direction. [0004] Half-duplex Communication (Half-duplex Communication) This communication method can realize two-way communication, but it cannot be carried out in two directions at the same time, and must be carried out alternately. [0005] Full duplex (Full duplex Communication) allows data to be transmitted in two directions at the same time, also known as two-way simultaneous communication, that is, both parties to the communication can send and receive data at the same time. ...
