Abstract
The utility model discloses USB of every USB mouth power of ability single control HUB includes USB owner's equipment, and it is equipped with the treater, the USB concentrator, it is equipped with a plurality of USB socket, its with USB owner's equipment is connected, power adapter, its with the power source of USB concentrator connects. The utility model discloses an above -mentioned topological structure can realize carrying out independent power supply to the USB concentrator to avoided because the too big problem that leads to unable discernment USB equipment of some abruptly electric current of the moment has ensured that stabilizing circuit connects between USB HOST (USB owner's equipment) and the USB SLAVE (USB slave unit). One, every USB mouth is independently supplied power, two, the switch of every USB mouth power can be controlled by the USB host computer, and the transmission mode that control had been ordered has three kinds: 1, the USB interface, 2, the serial ports, 3: the GPIO interface.
Description
Technical field
The utility model is related to a kind of USB-HUB equipment, more particularly to a kind of power supply control for technical grade USB device
Tubulation is managed.
Background technology
USB (English：Universal Serial Bus, abbreviation：USB) be connection computer system with it is outer
A kind of serial bus standard of portion's equipment, is also a kind of technical specification of input/output interface, is widely used in personal electricity
The information communication product such as brain and mobile device, and other are related to extend to photographic goods, DTV (Set Top Box), game machine etc.
Field.Latest generation is USB 3.1, and transmission speed is 10Gbit/s, three-stage voltage 5V/12V/20V, maximum power supply 100W,
New Type C insert type and no longer divide positive and negative.
USB is an external bus standard, for being connected and communicate with for specification computer and external equipment.USB interface is inserted
Use and warm connection function.USB interface can connect 127 kinds of peripheral hardwares, such as mouse and keyboard.USB is special by English in the end of the year 1994
Your Deng Duo companies combine after release in 1996, serial ports and parallel port have successfully been substituted, it has also become current computer and a large amount of intelligence
Equipment must match somebody with somebody interface.USB versions experienced development for many years, and 3.0 versions are had developed into by now.For most of engineerings
For teacher, exploitation USB2.0 interface product major obstacles are：To face complicated USB2.0 agreements, oneself write USB device
Driver, be familiar with the programming of single-chip microcomputer.This does not require nothing more than suitable VC programming experiences, can also write USB interface
Hardware (firmware) program.So most people abandons oneself exploitation USB product.In order to by complicated question simplification, Xi'an
USB2.0 protocol conversion modules have been specifically designed up to safe electronics.USB20D modules can be counted as turning for USB2.0 agreement
Parallel operation, is a transparent parallel bus by the USB2.0 interface conversions of computer, the same as microcontroller bus.So as to several days it
Inside can just complete the design of USB2.0 products.
USB device mainly has advantages below：
1. can be with hot plug.It is exactly user when using external equipment, it is not necessary to which shutdown such as is started shooting again at the action, but in electricity
When brain works, directly USB is plugged and is used.
2. easy to carry.USB device is good at " little, light, thin " mostly, for user, carries with mass data
When, easily.Certainly USB hard disks are primary choosings.
3. standard unification.The hard disk of everybody commonly ide interface, the mouse-keyboard of serial ports, the printer scanning of parallel port
Instrument, but have after USB, and these completely can be connected with same standard using peripheral hardware with PC, at this moment just be had
USB hard disks, USB mouse, USB printer etc..
4. multiple equipment can be connected.USB often has multiple interfaces on PC, can simultaneously connect several setting
It is standby, if connect one and have the USB HUB of four ports, it is possible to connect again；Four USB devices, by that analogy, to the greatest extent can be with
Company goes down, and the equipment of your family is all connected on a PC without there is any problem (note simultaneously：Highest may be connected to
127 equipment).
Although using USB as the main frame of interface and equipment connection in technical grade field large-scale application, still
There are several lower Railway Projects to obtain effectively solving：
1) main frame usb interface standards electric current is usually a fixed value, such as 1A, 0.5A.The wink of present many usb equipment
Between electric current even can reach more than 1.5A, cause electricity shortage because some moment unexpected electric current is excessive, this scene will
Cause the usb equipment cannot normal work.
2) USB device typically make by the way of main frame if there is failure using artificially plugging USB device or can only be restarted
It recovers normal work.And under the scene of technical grade, be often difficult to be found in time, and affect normally to use.
3) some usb equipment can be used common to solve the problems, such as mentioned above first electric current electricity shortage
Usbhub individually powers.But often whole system is simply in the work of the finite time section such as daytime, working day, if long-term continuous
Electricity, can cause usb service life of equipments to reduce.
4) as USB-HUB equipment, multiple USB devices may be simultaneously connect in practical application, some equipment breaks down,
Some equipment, once only one of them or several USB devices need power-off restarting, can only be adopted whole just in normal work
The mode of individual HUB power-off is performed.
If 5) can realize that timed power on/off can so significantly improve the service life of usb equipment.
