Description

The function expansion card of the usb bus interface based on PCI-E structure

Technical field

The utility model belongs to plant controller, specifically related to a kind of function of the usb bus interface based on PCI-E structure Expansion card.

Background technology

At present, the Function Extension board in computer realm PCI-E standard (PCI Express) is widely used, however, PCI-E standard interface adopts high-speed differential signal transmission data, and this puts forward higher requirement to board design and wiring, no The hardware team possessing high-speed PCB design ability cannot develop high speed, stable, reliable PCI-E computer function extension Board.

On the other hand, the development of usb bus interfacing is also with rapid changepl. never-ending changes and improvements, is typically exposed to outside computer casing USB Host interface is also to draw from computer motherboard power inside cable, computer motherboard generally has multichannel USB Host and connects Mouth socket.

In view of this, need to develop a kind of brand-new can based on PCI-E standard frame for movement and connect using usb bus The Function Extension board that mouth is communicated with computer motherboard.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of work(of the usb bus interface based on PCI-E structure Energy expansion card, with computer motherboard can be communicated based on PCI-E standard frame for movement and using usb bus interface.

In order to solve above-mentioned technical problem, the utility model adopts the following technical scheme that：

A kind of function expansion card of the usb bus interface based on PCI-E structure, including board body, board body sets Have PCI-E interface plate, USB Device interface socket, board power-supplying circuit, processor, Function Extension interface circuit, Each Function Extension interface, PCI-E interface plate is in order to insert the PCI-E interface slot of computer motherboard, and connects to board electricity The input of source power supply circuits, USB Device interface socket is connected by usb bus cable to the USB of computer motherboard Host interface socket, the output end of USB Device interface socket is also connected to board power-supplying circuit, and USB Device connects Mouth socket is also sequentially connected with processor, Function Extension interface circuit, each Function Extension interface.

Described processor is USB Device special chip.

Described processor is MCU or MPU of the controller of Device containing USB.

Described Function Extension interface includes switching value interface, analog quantity interface, communication class interface.

Several functional indicator lights are additionally provided with described board body, Function Extension interface circuit also with functional indicator light phase Even.

Using the function expansion card using the usb bus interface based on PCI-E structure of the present utility model, have following several Individual advantage：

1st, can be from usb bus interface power taking it is also possible to from PCI-E interface power taking.

2nd, can be communicated with computer motherboard by usb bus cable.

3rd, realize USB Device communication protocol by processor, and Function Extension interface circuit is controlled.

4th, pass through Function Extension interface circuit, to realize the interface functions such as switching value, analog quantity, communication class and necessary finger Show lamp control.
