AI Technical Summary

Problems solved by technology

[0003] However, the current asynchronous serial communication is not only complicated in encoding and decoding, but also needs to add too many information bits, which increases the overhead of message transmission, and usually asynchronous serial communication is only used for point-to-point message transmission

Embodiment Construction

[0073] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0074] The basic idea of ​​the embodiment of the present invention is: in the process of asynchronous serial communication, a new codec method is used to process the message to be transmitted, so that in the process of message transmission, the extra overhead is reduced, and it can also Used for point-to-multipoint message transmission.

[0075] Based on the above basic idea, see figure 1 , which shows an application scenario provided by the embodiment of the present invention, the sending end 10 and three receiving ends 20, 30 and 40, and the sending end 10 and each receiving end are connected and transmitted through a single transmission line 50 data. The embodiment of the present invention only illustrates the technical solution by taking the connection and data transmiss...

Abstract

Disclosed in an embodiment of the present invention are a message transmission method, device and system. The method comprises: a transmission terminal sets synchronization header data having a fixed number of bit, the synchronization header data being used to indicate a start of a message to be transmitted and a type of the message to be transmitted; according to a data value of the message to be transmitted, the transmission terminal executes a verification to obtain a verification value of the message to be transmitted; the transmission terminal takes the synchronization header data, the data value and the verification value of the message to be transmitted in sequence to compose serial data corresponding to the message to be transmitted, and transmits the serial data to a receiving terminal via a transmission line.

Description

technical field [0001] The present invention relates to data communication transmission technology, in particular to a method, device and system for message transmission. Background technique [0002] Serial communication refers to a communication method that transmits message data bit by bit on a single transmission line. In application scenarios that do not require high message transmission efficiency, serial communication can effectively save data transmission lines. In the case that the sending end and the receiving end do not have strict synchronization requirements on their respective clocks, asynchronous serial communication sends the data frame by frame after the data is formed into character frames, and is received by the receiving end frame by frame through a single transmission line. In this way, clock synchronization can be avoided by setting a clock line at the sending end and the receiving end. [0003] However, the current asynchronous serial communication i...
