Abstract
The invention discloses a USB HUB. The USB HUB comprises an HUB chipset achieving a traditional USB HUB central function, a detection module and a control module; the HUB chipset is communicated with an upper computer through an upstream interface and communicated with external equipment through a downstream interface; the detection module is used for detecting the state of the external equipment through the downstream interface and transmitting detection data to the upper computer through the upstream interface; the control module is used for receiving a control signal of the upper computer through the upstream interface and sending the control signal to specified external equipment through the downstream interface. The USB HUB has the advantages that pure central equipment is transformed into a USB expansion device with detection and control functions, and the function that the upper computer directly completes detection and control over the external equipment through a USB interface is effectively achieved. Compared with traditional serial interface connection, the USB HUB is more convenient and rapid, other peripheral detection is not needed, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of usb hub.
Background technology
In the system of the atm/crs of vtm, stm and a new generation, the data transfer central role that usb hub serves as, usb
The property relationship of hub to the performance of whole system, so, system transfer rate to be improved and sophisticated systems, traditional usb hub is not
Can complete.Atm master controller mainly controls paper money door module, panel ledss by master devices, DC motor Driver module, movement
Control module, sensor detection module, relay control module, audio-frequency module, serial communication modular and usb communication module and
Power module forms.These modules are only used as communication backbone by usb hub, are not controlled.Vtm, stm and new one simultaneously
During the atm/crs in generation uses, in order to improve communication speed further, so replaced traditional in such devices with usb bus
Serial bus, and industry control whole machine usb interface quantity is limited, needs to extend using usb hub, and traditional usb hub only has
It is confined to the extension of usb it is impossible to adapt to the function interface of vtm, stm and the demand of aspect of performance.
Content of the invention
In order to solve above-mentioned technical problem, present invention aim at offer is a kind of and can detecting and control ancillary equipment
usb hub.
A kind of usb hub of the present invention, including the hub chipset realizing traditional usb hub maincenter function, hub core
Piece group is communicated with host computer by Upstream Interface, is communicated it is characterised in that also including with external equipment by downstream interface:
Detection module, for detecting external equipment state by downstream interface；By Upstream Interface, detection data is transferred to
Position machine；
Control module, for receiving the control signal of host computer by Upstream Interface；By downstream interface, control signal is sent
To specified external equipment.
A kind of usb hub of the present invention, has an advantage in that, simple maincenter scrap build is with detection control
The usb expanding unit of function, effectively realizes the work(that host computer directly completes to external equipment to detect and control by usb interface
Energy.It is more conveniently and quickly, without other periphery detections more cost-effective than traditional serial ports connects.
Described inspection module by downstream interface detect external equipment parameter include: voltage, electric current, working condition,
Transfer rate, driving condition.
Described control module is included by the control signal that downstream interface exports to external equipment: wake-up signal, hang-up
Signal, Restart Signal, stopping signal.
Brief description
Fig. 1 is a kind of structural representation of usb hub of the present invention.
Fig. 2 is a kind of workflow diagram of sub hub of the present invention.
Specific embodiment
According to Fig. 1, a kind of usb hub of the present invention, including the hub realizing traditional usb hub maincenter function
Chipset, hub chipset is communicated with host computer by Upstream Interface, is communicated with external equipment by downstream interface；Also include: inspection
Survey module, for external equipment state is detected by downstream interface；Detection data is transferred to by host computer by Upstream Interface；Control
Molding block, for receiving the control signal of host computer by Upstream Interface；Send control signals to specify by downstream interface
External equipment.
Described inspection module by downstream interface detect external equipment parameter include: voltage, electric current, working condition,
Transfer rate, driving condition.Described control module is included by the control signal that downstream interface exports to external equipment: wakes up
Signal, pending signal, Restart Signal, stopping signal.
A kind of described usb hub can be extended from the usb2517i of microchip, and this chip supports that 1 drags 7
Mouth usb2.0, the design innovative point is to the addition of detection and control module, when using usb hub extension ancillary equipment,
Can be by using usb hub testing equipment running status and working condition.Detection module can adopt st company
Stm32f103r8t6 is master controller, can accomplish, to usb Data Detection and state-detection, external equipment is such as detected and be in
During over-current state, send control signal and soft protection is carried out to external equipment.This error message is reported to the police by detection module simultaneously upwards,
By information Real-time Feedback to host computer.In external equipment free time, usb hub can set output pending signal to external, make
Power consumption is minimum in an idle state to obtain whole equipment, decreases the power consumption of whole system simultaneously.
When main frame normally connects the work of (movement, strip printer, code keypad, paper money door, card reader etc.) external equipment,
Usb hub singly may only not provide sufficient usb mouth to expand to these equipment, can also be right during external equipment uses
These equipment are detected and are controlled, such as card reader, can detect by usb hub whether card reader working condition normal,
Whether external equipment drives and connects, runs the parameters such as whether power current is normal, whether transmitted data rates are normal to judge it
Whether work exception.If there is exception, host computer sends termination order by usb hub and external equipment is made by force
Reset or terminate operation, then carry out, to error feedback, allowing customer service carry out Emergency Maintenance by host computer background server, with
When whether normal condition can be in real-time watch device so that machine is more reliable and intelligent, in its idle condition, upper
Machine sends pending signal to external equipment and is changed into suspended state, reduces power consumption, right again after external equipment is operated again
External equipment sends wake-up signal and is waken up.
Usb hub of the present invention is carried to operation principle on stm and flow process as shown in Fig. 2 sub hub and stm
Hardware is initialized, and then hub connects host computer and drives, and whether downstream interface is in place to equipment cycle detection.Equipment is in place
After detection normally, normally whether detection data speed and equipment run, if normally, host computer carries out data acquisition, controls display
Idle hang-up and maintenance with equipment.If improper, display device/communication port error notifies host computer to show and safeguards shape
State.
For a person skilled in the art, can technical scheme as described above and design, make other each
Plant corresponding change and deformation, and all these change and deformation all should belong to the protection model of the claims in the present invention
Within enclosing.
