The invention discloses an industrial Ethernet switch looped network rapid network unlocking method and system and a storage medium, and the method comprises the steps: setting the corresponding portand looped network identifier of each switch in a looped network to be in the same state, electrifying a looped network link, and enabling each switch to send a looped network packet to the switch connected with the switch; comparing MAC address sizes, when the MAC address ratio of the ring network packet received by the switch is smaller than that of the switch, changing to a slave machine and stopping a ring network packet from being sent; when two ports of the ring network supported by a current switch are both in an open state, forwarding communication data, changing data messages receivedby other switches in the ring network from the current switch into slaves, and enabling ports of all the slaves except a host in the ring network to be in an open state, and realizing rapid network opening of the ring network. According to the invention, the port and the looped network identifier of each switch are preset to be in the same state, and the state of the switch is changed by comparing the MAC addresses, so that the looped network can be quickly disconnected.
Description
technical field [0001] The invention belongs to the technical field of communication, in particular to a method, a system and a storage medium for quickly unblocking a ring network of an industrial Ethernet switch. Background technique [0002] With the development of society, Internet technology has developed by leaps and bounds. People can remotely control electrical appliances at home through the Internet. Similarly, people can also use the Internet to remotely control machines and equipment in workspaces where people cannot go, such as high temperature and high pressure. Working environments with a high risk factor such as production workshops require remote control in industrial production or manufacturing processes, and the Internet must be built based on remote control. [0003] Industrial Ethernet switches are the core networking equipment of Ethernet, mainly used in industrial networking platform groups, with self-diagnosis function, can diagnose faults in a very sh...
