Embodiment 1

[0025] figure 1 It shows the internal structure of the industrial Ethernet switch of the present invention, in addition to the original module of the switch, it also includes a 4G communication module and a processor.

[0026] The processor is used to regularly detect the working state of the switch, and when it is detected that the switch cannot communicate normally, the 4G communication module is controlled to send the data packet to be sent to the 4G communication module of the target switch.

[0027] Generally speaking, the switch will record the connection status of each communication port in log form, and the connection status is also called link status. The processor can judge whether the communication port of the switch communicates normally by reading the link state of the communication port of the switch. When the link state is invalid, it is considered that the switch cannot communicate normally. Specifically, the communication port is an optical port.

Embodiment 2

[0029] In order to reduce the communication pressure of the backup network, people treat the sent data in advance with a timeliness mark according to certain rules, such as putting a timeliness mark on the data packets containing emergency notifications or security accident alarms.

[0030] When detecting that the switch cannot communicate normally, the processor controls the 4G communication module to send the data packet to be sent and with the aging mark to the 4G communication module of the target switch.

[0031] Method embodiment one

[0032] The communication method supporting network backup provided by the present invention includes:

[0033] Step 1: Establish an optical communication connection between the first Ethernet switch and the second Ethernet switch, and simultaneously establish a 4G backup network connection between the two; see figure 2 .

[0034] Step 2: The first Ethernet switch transmits the data packet to be sent to the second Ethernet switch through...

Abstract

The invention discloses an Ethernet switch and a communication method supporting network backup, and relates to a data transmission technology of industrial Ethernet switches. In the prior art, industrial Ethernet switches communicate via an optical fiber or a network cable. When a switch fails, the switch cannot transmit a data packet to a target switch in time via an optical fiber or a network cable. In order to solve the problem, the invention provides an Ethernet switch and a communication method supporting network backup. The main technical point is that the Ethernet switch comprises a 4G communication module and a processor, and the processor is used for detecting the working state of the switch regularly and making the 4G communication module send a to-be-sent data packet to the 4G communication module of a target switch when detecting that the switch cannot carry out communication normally.

Description

technical field [0001] The invention relates to a data transmission technology of an industrial Ethernet switch, in particular to an industrial Ethernet switch supporting network backup and a communication method. Background technique [0002] In the prior art, industrial Ethernet switches communicate with optical fibers or network cables. However, when the switch fails, the data packets cannot be transmitted to the target switch through optical fiber or network cable immediately. In some industries that require high communication timeliness, this situation cannot be allowed to occur, and a solution needs to be proposed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an industrial Ethernet switchboard supporting network backup and a communication method for the above existing problems. The purpose is to transmit important data to the target switch through the backup network first when the switch fails. [0004...
