Self-recognition communication correction device, working method and computer equipment

Abstract

The invention relates to a self-recognition communication correction device, a working method and computer equipment, and the device comprises a correction circuit which receives an input signal of a communication line, sends the input signal to a communication circuit, and corrects a communication line sequence of the communication line according to a control instruction when receiving the control instruction sent by an isolation circuit; the communication circuit sends the input signal to the identification circuit; the identification circuit identifies the input signal, judges whether a communication line is normal according to an identification result, and feeds back the signal to the isolation circuit; the isolation circuit sends a control instruction to the correction circuit according to the feedback signal; and the correction circuit corrects the communication line sequence of the communication line according to the control instruction. Through transmission and identification of the communication line, a signal can be fed back to the isolation circuit when the communication line is abnormal, and the isolation circuit controls the correction circuit to correct the communication line, that is, the sequence of the two data lines is corrected, so that normal communication is realized, and communication faults are avoided.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular to a self-identification communication correction device, a working method and computer equipment. Background technique [0002] Computer communication methods can be divided into parallel communication and serial communication according to the transmission characteristics. The corresponding communication bus is called parallel bus and serial bus, while the commonly used RS485, CAN and UART communication are all serial communication, and the data lines are for two. That is, one is B\H\TX, and the other is A\L\RX. In most cases, these three communication methods use polarized communication methods. [0003] In the related art, because the serial communication adopts a polarized communication mode, that is, the order of the two data lines cannot be exchanged, otherwise the communication will not be possible, resulting in frequent communication failures during u...
