Communication interface matching method, device and controller

Abstract

The embodiment of the invention discloses a communication interface matching method, a device and a controller. The communication interface is arranged in a mode that the Baud rate can be configured; each communication interface is connected with a bus network; specifically, when the communication interfaces are matched, first data transmitted from a first bus network connected with the first communication interface are received through the first communication interface; when confirming that the first data are correctly transmitted and the formats of the first data are matched with a first preset format, the matching is definitely accomplished, or else the Baud rate of the first communication interface is reconfigured and subsequently data transmitted from the first bus network are received, then self-adaptive matching of the communication interfaces is achieved, the corresponding relationship of the interfaces and the bus network can be confirmed without checking an operation instruction, and thus the networking efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a communication interface matching method, device and controller. Background technique [0002] In a controller system composed of multiple bus networks conforming to the same bus standard, multiple identical physical interfaces are set on the junction controller of one bus network and another bus network (that is, multiple physical interfaces conform to The interface of the same bus standard), but these interfaces are in different bus networks, and the communication rate and communication protocol are different. If it is wrongly inserted, the entire control system will not be able to communicate normally. [0003] At present, when networking, it is necessary to check the instruction manual to determine the corresponding relationship between the physical interface and the bus network in order to perform correct networking, and the networking effici...

Problems solved by technology

[0002] In a controller system composed of multiple bus networks conforming to the same bus standard, multiple identical physical interfaces are set on the junction controller of one bus network and another bus network (that is, multiple physical interfaces conform to The interface of the same bus standard), but these interfaces are in different bus networks, and the communication rate and communication protocol are different. If the wrong connection is made, the entire control system will not be able to communicate normally

[0003] At present, when networking, you must check the instruction manual to determine the corresponding relationship between the physical interface and the bus network in order to perform correct networking, and the networking efficiency is low.
