Abstract
The utility model discloses a USB interface conversion device. The device comprises a USB interface, a USB-UART conversion chip, an RS232 serial port chip, a line order change-over switch, a serial port interface and an Internet access interface, wherein the USB interface, the USB-UART conversion chip, the RS232 serial port chip, the line order change-over switch, and the Internet access interface are sequentially connected, and the Internet access interface is connected with the line order change-over switch. The USB interface conversion device provided by the utility model supports multiple interface connection modes.
Description
Technical field
The utility model relates to the communications field, relates in particular to a kind of USB interface conversion equipment.
Background technology
The router of prior art or switch all need to use serial ports when carrying out hardware and software debugging, system management control or fault eliminating.And present desktop computer computer, what have on its mainboard carries a serial ports, and much be not with serial ports, the notebook computer that moves does not have this interface especially, for commissioning device, need purchase serial port board or serial ports platelet separately, and present serial port board or serial ports platelet all can only provide single interface, cause when the machine of debugging distinct interface, will changing serial port board or serial ports platelet.
Fig. 1 is a kind of schematic diagram of serial ports conversion equipment of prior art, and it is connected to by pci interface on the pci interface of computer main board, outputs to DB9 serial port by the serial ports connect chip
Fig. 2 is the schematic diagram of the serial ports conversion equipment of another kind of prior art, and it is connected to by USB interface on the USB interface of computer, outputs to DB9 serial port by the serial ports connect chip.
Yet there are the following problems for the test of the Power over Ethernet of prior art: the serial ports connected mode of the row's of providing pin not; If the client just need not be connected on the serial ports of equipment when not having special-purpose Serial Port Line; The interface shape that provides is single; When the interface line preface is inconsistent, can't switch.
The utility model content
In order to solve the problems referred to above of prior art, be necessary to provide a kind of USB interface conversion equipment that is applicable to multiple interfaces.
The technical scheme that the utility model technical solution problem provides is:
A kind of USB interface conversion equipment, it comprises USB interface, USB-UART conversion chip, RS232 serial port chip, line preface diverter switch, serial interface and network interface interface, USB interface, USB-UART conversion chip, RS232 serial port chip, line preface diverter switch, network interface interface connect successively, and the network interface interface is connected with line preface diverter switch.
Wherein, also comprise a row's needle interface that is connected with the USB-UART conversion chip.
Wherein, described serial interface is a DB9 serial port.
Wherein, described network interface interface is the RJ45 network interface.
Compared to prior art, USB interface conversion equipment of the present utility model provides whole RS232 serial ports connected modes, can not adopt common netting twine to connect when having special-purpose Serial Port Line to connect, and goes back Support Line preface handoff functionality.

Fig. 1 is the block diagram of the USB interface conversion equipment of prior art.
Fig. 2 is the block diagram of the USB interface conversion equipment of prior art.
Fig. 3 is the block diagram of USB interface conversion equipment of the present utility model.
Embodiment
As shown in Figure 3, USB interface conversion equipment of the present utility model comprises USB interface, USB-UART conversion chip, row's needle interface, RS232 serial port chip, line preface diverter switch, serial interface, network interface interface.USB interface, USB-UART conversion chip, RS232 serial port chip, line preface diverter switch, serial interface connect successively.The network interface interface is connected with line preface diverter switch.Row's needle interface is connected with USB-UART conversion chip and RS232 serial port chip.Serial interface can adopt DB9 serial port.The network interface interface can adopt the RJ45 network interface.
USB interface is used for being connected with USB interface of computer.The USB-UART conversion chip is used for usb data is changed, and converts thereof into the serial data that can directly export by row's needle interface.Data after the RS232 serial port chip will be changed are converted to the RS232 serial data.Because each producer is not quite similar in VCC, GND, TX, the RX line preface of definition serial ports,, the utility model switches so adopting line preface diverter switch to carry out the line preface.After the switching of line preface, can export by serial interface, can also be by the output of network interface interface.
When the user does not have special-purpose RS232 Serial Port Line, can be connected to the RJ45 network interface by connecting a common netting twine, play the effect identical with special-purpose Serial Port Line; When user's serial ports is row's pin connected mode, the user is directly on the row of the being wired to needle interface, thereby realized the multi-functional interconnecting device of support multiple interfaces mode.
Compared to prior art, USB interface conversion equipment of the present utility model provides whole RS232 serial ports connected modes, can not adopt common netting twine to connect when having special-purpose Serial Port Line to connect, and goes back Support Line preface handoff functionality.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
