Abstract

The invention discloses a method for sending and receiving data by a circuit board, a circuit board and a storage medium. The method for sending and receiving data by a circuit board is applied to a circuit, and the circuit board is provided with a network switching sheet for connecting to a network. The switching chip is provided with a first port and a second port, and the method for sending and receiving data on the circuit board includes: sending and receiving data through the first port, and monitoring the state of the first port; when the state of the first port is When a fault occurs, detect the state of the second port; when the state of the second port is normal, switch to send and receive data through the second port. The present invention provides a spare network port for the circuit board, so that the circuit board can switch to the spare network port to send and receive data when the network connection of the current network port fails, and realizes the redundant protection of the network port for sending and receiving data of the circuit board , improving the reliability of the function of transmitting and receiving data of the circuit board.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a method for sending and receiving data by a circuit board, a circuit board and a storage medium. Background technique [0002] In the circuit board for data processing, generally, a DSP (Digital Signal Processing, digital signal processing technology) chip provided on the circuit board is used to encode and decode data packets, and then transmit and receive data packets through network ports. Because the business function of this kind of circuit board is single, the probability of failure of the circuit board itself is very low. However, because this kind of circuit board needs to process a large amount of data flow, the requirements for the network are relatively high, and the probability of failure of the network connection is relatively high. larger. In the existing products, this kind of circuit board is only equipped with one network port, and there is no redundant ...
