Description
Technical field
The utility model relates to electronic device field, relates in particular to a kind of computer interface expansion equipment field, specifically is meant a kind of The Design of Tax Controled Device expansion control device of multi-to-multi USB interface.
Background technology
The Design of Tax Controled Device is as one of a kind of product that solves the tax revenue electronization, and it can realize tax control function well, is meant the electronic installation of under computing machine or the cooperation of other electronic equipment, realizing tax control function.Can guarantee that management data correctly generates, reliably stores and safe transmission, satisfies the management and the data check requirement of the tax authority.
The tax jurisdiction of a lot of units at present entrusts tax accountant office to act on behalf of usually, thereby, in a tame tax accountant office, to use The Design of Tax Controled Device usually to satisfy service request to each enterprise.Because The Design of Tax Controled Device is connected on the main frame through interface, thereby, to a core technology of main frame interface expansion will becoming tax controlling equipment application.
At present, the also common use of the mode PCI expansion interface mode of The Design of Tax Controled Device and computing machine connecting interface, though the PCI expansion interface has fast the having a few of data transmission, structure is comparatively complicated, the higher shortcoming of cost because its interface also exists simultaneously.Along with the development of USB interface transmission technology, the USB transmitting speed also improves greatly, and because it has advantage of simple structure, at present on various computer peripheral equipments, to be used widely.
In the The Design of Tax Controled Device field; The The Design of Tax Controled Device that USB interface also occurred at present; But in the occasion of many The Design of Tax Controled Device of uses such as tax accountant office, because every USB device all will independently take a USB interface, the quantity of USB interface then is limited; Thereby, USB interface be expanded into a key issue.
According to the agreement regulation of usb bus, the 5V power voltage supply is adopted in the USB interface power supply, and supply current generally also is no more than 500mA, and therefore, the power consumption of UBS equipment all is limited not too large.The equipment that some USB expansion interfaces also occurred at present, but because the UBS power supply power supply of USB host computer is also still used in the power supply of these interfacing equipments fully, thereby it is very limited to cause expanding quantity.
In addition, at present also the someone has proposed to adopt the USB interface expanding unit of independent current source power supply, knows that like state the board web publication number is that the patent of invention document of CN101425049A just discloses a kind of " based on subscriber equipment and the data channel switching method of USB "; This patent documentation promptly disclose a kind of utilization independently power-supply management system USB device supplies power to carrying out; Realized purpose that USB device is expanded, though the usb data bus control through multiway analog switch, simultaneously since power-supply management system USB device is supplied power; In use; Power-supply management system is in power supply state to USB device always, and energy consumption is bigger, particularly for The Design of Tax Controled Device; Because in use; In most cases just when a certain The Design of Tax Controled Device used, just this The Design of Tax Controled Device is opened and reading of data therefrom, adopted the disclosed technical scheme of above-mentioned patent documentation then energy consumption to be caused necessary waste, energy-saving effect is bad.
In addition, existing tax control machine normally only is connected with a main frame or server, during use, can only carry out the tax control operation of The Design of Tax Controled Device through this main frame, if many people use simultaneously, has then caused many inconvenience.
The utility model content
The technical matters that the utility model will solve is to the existing in prior technology weak point, provide a kind of can realize to USB interface expand in enormous quantities, energy-saving effect better and the The Design of Tax Controled Device expansion control device of the multi-to-multi USB interface that can simultaneously many people uses.
The technical solution of the utility model is; The The Design of Tax Controled Device expansion control device of following a kind of multi-to-multi USB interface is provided; Comprise respectively at least two usb data interfaces, USB power-supply management system, multiway analog switch I, multiway analog switch II and at least two USB expansion interfaces of being connected one by one with at least two main frames that have a USB interface; Wherein, Described multiway analog switch I with at least two USB interfaces that have the main frame of USB interface is connected respectively through described two usb data interfaces at least, and is connected with at least two USB expansion interfaces respectively through the usb data passage; Described multiway analog switch I through control interface control, switches the usb data passage by at least two main frames that have USB interface at least between described two USB expansion interfaces; Described USB power-supply management system is electrically connected through the USB power channel with described two USB expansion interfaces through multiway analog switch II at least, and described USB power-supply management system is given through the USB power channel and is connected USB device power supply at least two USB expansion interfaces; Described multiway analog switch II through control interface control, switches the USB power channel by at least two main frames that have USB interface at least between described two USB expansion interfaces.
After adopting above scheme; The The Design of Tax Controled Device expansion control device of the utility model multi-to-multi USB interface has adopted independent USB power-supply management system that the USB device that uses the USB expansion interface is supplied power; Thereby the USB interface of the expansion supply current that can not be subject to usb protocol regulation generally also is no more than the requirement of 500mA, can realize the expansion in enormous quantities of USB interface, in addition; Because the usb data passage and the USB power channel of described USB interface are carried out the control of switch through multiway analog switch I and multiway analog switch II respectively; And the control of switch receives host computer control through control interface respectively, thereby in use, can be according to the needs that use; Using which USB expansion interface then to utilize the control interface control multiway analog switch I of main frame and usb data passage and the USB power channel that multiway analog switch II opens corresponding USB expansion interface; Avoided unnecessary energy consumption, energy-saving effect is also better, in addition; Because the utility model can realize that main frame more than at least two uses simultaneously and reads data in the USB expansion interface, realizes that many people use simultaneously.
As preferably, the quantity of described at least two USB expansion interfaces is 12.Adopt this preferred version, can 12 USB expansion interfaces of disposable expansion.
As preferably, the quantity of at least two usb data interfaces that described and at least two main frames that have a USB interface are connected one by one is four.Adopt this preferred version, can use four host computer to carry out reading of USB expansion interface simultaneously, also four people use four host computer to realize many people co-operate simultaneously.
