Abstract

The present invention provides a communication method and device for a single board. Wherein, the method includes: when the host communicates with the slave through the communication bus, collecting the level signal on the communication bus; judging whether a communication failure occurs between the host and the slave based on the two level signals, wherein the two level signals The signal collection time interval is a preset length; in the case of a communication failure between the master and the slave, the master drives the communication bus to be in a communication idle state, where the communication idle state is a state that allows the master to communicate with the slave. The invention solves the technical problem in the related art that the communication bus of the single board cannot be recovered in time after hanging up.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a single board communication method and device. Background technique [0002] In the field of communication equipment, backplane communication is mainly the exchange of information between boards, such as the temperature of the board, the fan speed, and the presence of the board. In order to ensure the correct and stable transmission of information, the backplane communication is required to be stable and reliable. [0003] In the field of communication equipment, the inter-board communication of the backplane adopts various protocols, such as Ethernet protocol, serial communication protocol, and I2C protocol. The Ethernet protocol is characterized by stability and reliability, long transmission distance, and fast transmission rate (which can easily reach 100M). It is the most ideal backplane communication protocol, but its shortcomings are also obvious. The protocol is complex and ...
