Switch capable of customizing line sequence of protocol line

Abstract

The invention discloses a switch capable of customizing a protocol line sequence, wherein the switch comprises a first interface and a second interface which are respectively disposed at two ends of a protocol line; at least two relay groups, which are respectively connected with the first interface and the second interface, wherein the first interface and the second interface are connected through the relay groups according to a user-defined line sequence; a control unit which is connected with the relay set and controls the relay set to work; and an upper computer which is connected and communicated with the control unit, and a line sequence between the first interface and the second interface is customized through the upper computer. The switch capable of customizing the wire sequence of the protocol wire is high in safety and stable in communication, and the short circuit phenomenon caused by wiring errors is not prone to occurring. When the wire sequence needs to be replaced, the wire sequence can be customized and set through the upper computer, so that the wiring reliability and efficiency are high, the compatibility is good, and the method can be suitable for different non-standard application scenes. The whole system is free of messy wires, and is good in appearance and easy to maintain.

Description

【Technical field】 [0001] The invention relates to a wiring device, in particular to a switch capable of customizing the sequence of protocol lines. 【Background technique】 [0002] Protocol lines usually use network port hardware to communicate with standard interfaces. When industrial buses such as RS485, 232, CAN, etc. use network port hardware to communicate with standard interfaces, it is necessary to select the corresponding line sequence between the network port and the standard interface. connection to send and receive information. The existing wiring method between the network port and the standard interface is to convert the standard interface into a terminal block, and then carry out the wiring manually, and then fix it with screws after the line is connected. When the network port or interface needs to be replaced, it needs to be re-wired, which is not only inefficient, but also easy to connect wrongly, resulting in short circuit or open circuit. On the other han...

AI Technical Summary

Problems solved by technology

When you need to replace the network port or interface, you need to re-wire, which is not only inefficient, but also easy to connect wrongly, resulting in short circuit or open circuit

On the other hand, the existing manual wiring method is also prone to poor contact and communication interruption

In addition, in the existing wiring method, there will be redundant miscellaneous wires, which will affect the appearance of the product
