Serial port data encoding method and device, embedded equipment and communication system

Abstract

The embodiment of the invention relates to the field of encoding communication, and discloses a serial port data encoding method and device, embedded equipment and a communication system. The serial port data encoding method comprises the following steps: acquiring serial port data; converting the serial port data of the target message format segment into serial port coded data of a preset system;judging whether the serial port coded data is smaller than or equal to a first preset numerical value of a preset system; if yes, adding a second preset numerical value of a preset system to the serial port coded data to obtain coded transmission data, so that the coded transmission data does not contain character type data; if not, splitting the serial port coded data into first split data and second split data which are both smaller than or equal to a first preset numerical value, and respectively adding a second preset numerical value of a preset system to the first split data and the second split data to obtain first split coded transmission data and second split coded transmission data, so that the first split coded transmission data and the second split coded transmission data do not contain character type data. According to the embodiment of the invention, the reliability of equipment communication is improved.

Description

Technical field [0001] The invention relates to the field of coding communication, in particular to a serial data coding method, device, embedded device and communication system. Background technique [0002] When the serial port data sent by the source device is communication data, its content includes the LINUX debugging command message. This part of the message will be intercepted by the bottom layer of the destination device, making the serial port data reaching the application layer of the destination device incomplete, resulting in device communication abnormal. Summary of the invention [0003] The embodiments of the present invention aim to provide a serial data encoding method, device, embedded device, and communication system, which can improve the reliability of device communication. [0004] To solve the above technical problems, the embodiments of the present invention provide the following technical solutions: [0005] In the first aspect, an embodiment of the present ...
