Abstract

The utility model belongs to the field of an electronic communication network and in particular relates to a line multiplexing device for transmitting serial bus data by the multiplexing Ethernet. The line multiplexing device comprises a main control chip, a network chip, a network transformer, a serial port chip, a connector and an ETH port, wherein one end of the main control chip is connected with the network chip and the other end of the main control chip is connected with the serial port chip; the serial port chip is fixedly connected with the connector; one end of the network chip is connected with the network transformer; the network transformer is fixedly connected with the ETH port; the other end of the network chip is fixedly connected with the ETH port directly; the connector is connected with an upper machine; the ETH port is connected with a lower machine; and the main control chip, the network chip, the network transformer, the serial port chip, the connector and the ETH port are correspondingly connected with one another to form the line multiplexing device for the multiplexing Ethernet serial bus data. By adoption of connection of a common operating environment (COE) line, Ethernet port to serial port equipment is eliminated, so the data format of the original serial port to serial port transmission is converted into network connection, the problems of distance restraint and equipment connection are solved, the original local physical path is replaced, a protocol on an application layer is protected and kept unchanged, and configuration work is finished.

Description

A kind of line sharing device of multiplexing Ethernet transmission universal serial bus data

Technical field:

The utility model belongs to the electronic communication network field, relates to a kind of line sharing device of multiplexing Ethernet transmission universal serial bus data specifically.

Background technology:

At present, in the transmission of Ethernet, conventional technical staff adopts two kinds of connection configurations more on to the configuration of equipment, one is to dispose by serial ports, two for to be configured by network, though these two kinds of configuration modes can be worked, has certain drawback, (1), dispose by serial ports, need all to possess serial ports by upper and lower computer, well-known, present notebook all gradually remove serial ports, cause the serial ports scope of application limited, moreover, the limited transmission distance of serial ports, common Serial Port Line, length is 1.5 meters, certainly, Serial Port Line can extend, still, when length increased, the decay of signal was also taking place; (2), the mode that is configured by network interface can be removed the drawback that is subjected to distance limit, but, need know in advance that the ip address of slave computer just can operate, still, after a collection of production comes out, there is not fixing ip, identical ip is perhaps arranged, perhaps the user in use, when having forgotten about for a certain reason changing the ip of equipment, configuration just can not be carried out, and gives in the transmission work of Ethernet like this and brings inconvenience.

Summary of the invention:

The purpose of this utility model has provided a kind of employing COE circuit connection, realizing can be remote, is not subjected to the line sharing device of a kind of multiplexing Ethernet transmission universal serial bus data of ip address, time restriction, to overcome above-mentioned deficiency.

The purpose of this utility model is realized by following technical scheme:

A kind of line sharing device of multiplexing Ethernet transmission universal serial bus data, comprise main control chip U1, network chip U2, network transformer U3, serial port chip U4, connector J1, ETH mouth J2, it is characterized in that: the end of main control chip U1 is connected with network chip U2, the other end is connected with serial port chip U4, serial port chip U4 is fixedly attached on the connector J1, the end of network chip U2 is connected with network transformer U3, network transformer U3 is fixedly attached on the ETH mouth J2, the other end of network chip U2 is directly fixedlyed connected with ETH mouth J2, connector J1 is connected with host computer, ETH mouth J2 is connected with slave computer, and correspondence connects to form the line sharing device of Ethernet transmission universal serial bus data mutually.

The utility model has the advantages that:

The utility model adopts the circuit of COE technology to connect; be that transmission is all finished via network with receiving data; just mean that slave computer can not have serial ports; only needing the ETH mouth gets final product; and save the equipment that network interface changes serial ports; making needs serial ports that the data of serial ports transmission are passed through certain protocol originally; specific form is converted to by network and connects; can utilize the COE technology to solve the restriction of distance; problems such as the connection of equipment; to go up; slave computer changes the network interface line with netting twine or serial ports above-mentioned and is connected on the consolidated network; host computer is installed our application software; on host computer, import configuration data, only need the ETH mouth and get final product, and save the equipment that network interface changes serial ports; making needs serial ports that the data of serial ports transmission are passed through certain protocol originally; specific form is converted to by network and connects, and the configuration effort that the local serial ports of any needs is finished can use network to replace original local physical pathway; and the agreement on the protection application layer do not changed, and finishes configuration effort.
