Abstract
A shared device comprises a machine shell, which is internally provided with power supply, a switching circuit, a switching controller, a communication circuit, and a plurality of extension slots; wherein, the switching circuit is connected with the switching controller and the communication circuit; the switching controller is connected with the communication circuit; the extension slots are connected with the switching circuit; the communication circuit is provided with communication interfaces. The utility model can be connected with a plurality of peripheral equipment, for example, the utility model can be connected with the anti-counterfeiting tax-control gold-tax card and realize one-machine multiple-card of anti-counterfeiting tax-control; the peripheral equipment realize the communication with the computer via the shared device.
Description
The utility model relates to a kind of shared device, is applied to computer control and communication.
At present, computer peripheral is a lot, but the interface of computing machine itself is less, how to make to calculate function and link to each other with more peripherals, so that allow computing machine work better, be a problem always.
The purpose of this utility model is to provide a kind of shared device, can realize linking to each other with a plurality of peripherals, and and computing machine between control and communication.
For achieving the above object, by the following technical solutions of the present utility model:
A kind of shared device comprises casing, and power supply, commutation circuit, switch controller, communicating circuit and many expansion slot also are installed in the casing; Wherein commutation circuit links to each other with switch controller, communicating circuit; Switch controller links to each other with communicating circuit; Expansion slot links to each other with commutation circuit; Communicating circuit is provided with communication interface.Many peripherals can be connected in respectively on the expansion slot like this, by the switching of commutation circuit, switch controller, and just can be with one or many peripherals by communicating circuit and computer realization communication.
Above-mentioned shared device is characterized in that the communication interface of described communicating circuit is respectively asynchronous interface and host interface.Host interface has realized the communication between shared device and the computing machine.The effect of asynchronous interface is, during the expansion slot quantity of and shared device many when peripherals, peripherals can be linked to each other with shared device respectively, utilize connecting line that the asynchronous interface of many shared devices is linked to each other again, most peripherals of measuring can be linked to each other with computing machine realize communication, that is to say that asynchronous interface makes shared device have certain extendability.
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the synoptic diagram of the utility model embodiment 1;
Fig. 3 is the synoptic diagram of the utility model embodiment 2;
Fig. 4 is the utility model circuit control flow synoptic diagram.
With reference to accompanying drawing, number in the figure and parts are: the host interface of expansion slot 1, commutation circuit 2, power supply 3, switch controller 4, communicating circuit 5, shared device 6, tax-supervise system Golden Taxes control card 7, tax-card 8, shared device, the asynchronous interface 10 of shared device.
Shared device described in the utility model comprises casing, and power supply 3, commutation circuit 2, switch controller 4, communicating circuit 5 and many expansion slot 1 also are installed in casing; Wherein commutation circuit 2 links to each other with switch controller 4, communicating circuit; Switch controller 4 links to each other with communicating circuit 5; Expansion slot 1 links to each other with commutation circuit 2; Communicating circuit 5 is provided with communication interface.The communication interface of communicating circuit is respectively asynchronous interface 10 and host interface 9.
Embodiment 1:
Among the figure, two tax-supervise system Golden Taxes control cards 7 are inserted in respectively in the expansion slot 1 of shared device, and control card 7 links to each other with card-reading apparatus respectively, and shared device 6 links to each other with main frame by the host interface of communicating circuit.By the switching of commutation circuit, switch controller, just can control each card-reading apparatus by communicating circuit respectively with the computer realization communication.
Expansion slot links to each other with card-reading apparatus, and after IC-card 8 sense datas, data flow to channel switching circuit by expansion slot, import main frame at last via communication module again.When needs switch different expansion slot, when obtaining the data of different card-reading apparatus, main frame sends the passage switch-over control signal to communication module, the passage switch-over control signal sends instruction via the passage switch controller to channel switching circuit again, makes main frame obtain the data of different expansion slot inputs.
Embodiment 2:
This realization example utilizes connecting line that the asynchronous interface 10 of many shared devices is linked to each other, and the realization computing machine is connected with more peripherals.
Claims (2)
1, a kind of shared device comprises casing, it is characterized in that also being equipped with in the casing power supply, commutation circuit, switch controller, communicating circuit and many expansion slot; Wherein commutation circuit links to each other with switch controller, communicating circuit; Switch controller links to each other with communicating circuit; Expansion slot links to each other with commutation circuit; Communicating circuit is provided with communication interface.
2, shared device as claimed in claim 1 is characterized in that the communication interface of described communicating circuit is respectively asynchronous interface and host interface.
