The first chip and the second chip are electrically connected to the several switches. Each switch is electrically connected to one USB output port. The first chip and the second chip control the USB output ports through the switches. When something goes wrong, substitution can be performed.
Description
Technical field
The present invention relates to electronic applications, particularly relate to a kind of usb hub.
Background technology
Along with the development of science and technology, computer becomes one of article indispensable in people's daily life, the fittings equipments of computer etc. are also day by day flourishing, USB obtains the favor of people as a kind of standard interface always, USB peripheral hardware also gets more and more, such as wireless mouse, mouse heater, USB fan, USB sound equipment etc., therefore, along with the increase gradually of these fittings equipments, the thing followed is that the USB interface of computer is crowded not enough, cause various use inconvenience, the appearance of usb hub solves this puzzlement of user, as a kind of translation interface, its demand is also very huge.
Usb hub is a kind of instrument of expanding USB interface, when deployed, USB interface can expand to multiple (being generally four) by usb hub, and these interfaces can be made to use simultaneously, in the prior art, unilaterally control multiple expansion interface by a control chip, when one of them expansion interface of usb hub go wrong can not use time, this expansion interface that then needs repairing just is used, otherwise people can only use remaining expansion interface, thus reduce the service efficiency of usb hub, increase maintenance cost, cause and use inconvenience.
Therefore, be necessary to provide a kind of by many-sided usb hub controlling expansion interface.
Summary of the invention
For above-mentioned situation, object of the present invention is mainly to provide a kind of by the first chip and the second chip control USB output port simultaneously, usb hub that can be alternative each other when going wrong.
For achieving the above object, the invention provides a kind of usb hub, comprising USB input port, some USB output ports, transport module, the first chip and the second chip, wherein:
USB input port, for being plugged in the USB connector of host computer;
Some USB output ports, for the some USB external equipments of grafting;
Transport module, for controlling the transfer of data between the USB external equipment that is connected with USB output port and host computer;
This usb hub also comprises the first chip, the second chip and some switches, first chip and the second chip and this switches some are electrically connected, this switch each is electrically connected this USB output port, and this first chip and the second chip are by this USB output port of this switch control rule.
Especially, described USB output port is electrically connected a current detecting module, and the detecting of this current detecting module flows through the current value of this USB output port.
Especially, described current detecting module is some ammeters.
Compared to prior art, usb hub of the present invention, by the first chip and the second chip control USB output port simultaneously, can replace controlling with another chip when the output port of arbitrary chip controls can not use, improve service efficiency.
[accompanying drawing explanation]
Fig. 1 is the connection block diagram of usb hub of the present invention.
[embodiment]
Usb hub of the present invention, control expansion interface by the first chip and the second chip simultaneously, can replace each other and load balance when going wrong, refer to Fig. 1, it is the connection block diagram of usb hub of the present invention, as shown in the figure, described usb hub 1 comprises USB input port 14, transport module 15, first chip 11 and the second chip 12, current detecting module 13, first switch 16, second switch 17, 3rd switch 18, 4th switch 19 and a USB output port 21, 2nd USB output port 22, 3rd USB output port 23 and the 4th USB output port 24.
Wherein, USB input port 14 is for being plugged in the USB connector of host computer 2, one USB output port 21, the 2nd USB output port 22, the 3rd USB output port 23 and the 4th USB output port 24 are for the some USB external equipments of grafting, transport module 15 is for controlling the transfer of data between the USB external equipment that is connected with a USB output port 21, the 2nd USB output port 22, the 3rd USB output port 23 and the 4th USB output port 24 and host computer 2, first chip 11 and the second chip 12 and the first switch 16, second switch 17, the 3rd switch 18, the 4th switch 19 are electrically connected, this first switch 16 is electrically connected a USB output port 21, second switch 17 is electrically connected the 2nd USB output port 22,3rd switch 18 is electrically connected the 3rd USB output port the 23, four switch 19 and is electrically connected the 4th USB output port 24, one USB output port 21, 2nd USB output port 22, 3rd USB output port 23 and the 4th USB output port 24 are electrically connected a current detecting module 13, the detecting of this current detecting module 13 flows through a USB output port 21, the current value of the 2nd USB output port 22 and the 3rd USB output port 23 and the 4th USB output port 24, calculate the current value summation of this USB output port of this first chip 11 and the control of this second chip 12, when the difference of both current value summations is greater than the electric current value difference of a setting, redistribute the quantity of this USB output port of this first chip 11 and the control of this second chip 12.
In the present embodiment, described current detecting module is an ammeter, and the electric current value difference of described setting is 0.4.
In the present embodiment, if the first chip 11 controls a USB output port 21 and the 2nd USB output port 22, second chip 12 controls the 3rd USB output port 23 and the 4th USB output port 24, for a USB output port 21, cannot use if it breaks down, then this first chip 11 makes this second chip 12 control a USB output port 21 by controlling this second switch 17, and other USB output ports in like manner, therefore make the first chip 11 and the second chip 12 realize replacing each other.If now current detecting module 13 detects: the current value of a USB output port 21 is 0.9, the current value of the 2nd USB output port 22 is 0.1, the current value of the 3rd USB output port 23 is 0.1, the current value of the 4th USB output port 24 is 0.1, therefore, the load of the first chip 11 is 1.0, the load of the second chip 12 is 0.2, both differences are the electric current value difference 0.4 that 0.8(is greater than setting), then control a USB output port 21 by the first chip 11, second chip 12 controls the 2nd USB output port 22, 3rd USB output port 23 and the 4th USB output port 24, to reach the load of balance first chip 11 and the second chip 12.
By reference to the accompanying drawings the specific embodiment of the present invention and embodiment are elaborated above, but the present invention is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, can also make a variety of changes without departing from the inventive concept of the premise.
