Embodiment
Anti-counterfeiting Tax Control Host Computer Shares Server in the utility model is connected with input/output device by the usb data line, and wherein input/output device can be IC card reader and computing machine.
As depicted in figs. 1 and 2, main frame share service device includes a rack 1, this rack 1 includes a cabinet 11 and an openable cabinet door 10, is set with serial bus concentrator, supply socket and the IC card reader communication serial hub that can be connected with computing machine, power supply, IC card reader on cabinet 11.
Be arranged with five main frame share service devices 2 up and down in parallel (quantity of this main frame share service apparatus can increase according to the big or small and different demands of rack and delete in rack 1 inside, be not limited to five), these five main frame share service devices 2 have included a drawer type cabinet body 20, be fixed with a slide rail 21 respectively in the both sides of cabinet 20, as shown in Figure 6, correspondingly the madial wall of the cabinet 11 of rack 1 is provided with a plurality of parallel slide rails, each main frame share service device 2 all is located in the rack 1 with drawer-type structure, and it is separate, be independent of each other, each main frame share service apparatus 2 is provided with a drawer-lock structure 25, as shown in Figure 1, because drawer type rail structure and door latch structure are prior art, no longer describe in detail for this reason.
As shown in Figure 3 and Figure 4, be provided with the central processing unit 23 that a tax-card device 22 and is used to control this tax-card device 22 in each main frame share service apparatus 2 inside, wherein: tax-card device 22 includes 16 tax-cards and is used to place the backboard of these 16 tax-cards that (quantity of this tax-card also can be 26, or adjust) according to different demands, tax-card places in the slot that backboard is set up in parallel, and the circuit of this slot as shown in Figure 5.Central processing unit 23 is a cpu motherboard, this cpu motherboard selects for use the chip PXA250 of the Xscale of INTEL Corp. series as cpu chip (wherein the physical circuit of cpu chip as shown in Figure 8), select the internal memory of the common 32M of W981216 of 2 Hua Bang companies for use, and select the E28F320 flash memory (FLASH) of 1 INTEL Corp. for use, be used to install the software of main frame share service apparatus, the standard A TX power-supply controller of electric that this cpu motherboard and can be independently-powered is connected simultaneously, and this standard A TX power-supply controller of electric is connected with power supply on being located at rack by power lead, so, be located at that power supply can be independently-powered to individual host share service apparatus according to different demands on the rack, also can be simultaneously to five or 2 power supplies of wherein any a plurality of main frame share service apparatus.Cpu motherboard is connected by the backboard of 32 * 3 contact pins 26 with the tax-card that is used to plant, and utilize the bridging chip of AIPCI-227A cake core 24 as tax-card device (PCI), bridgt circuit is provided, not only can finish the basic controlling of basic cpu motherboard after utilizing this bridging chip to the tax-card device, a plurality of tax-card devices simultaneously also can be connected in parallel, to reduce the frequency of tax-card device (PCI) bus, wherein the physical circuit of bridging chip as shown in Figure 7.Because cpu motherboard, tax-card, reference power supply, bridging chip, contact pin, internal memory and flash memory and annexation each other thereof are prior art, therefore no longer describe in detail.This single main frame share service apparatus 2 can directly be connected with computing machine, power supply and IC card reader, realizes working alone.
As shown in Figure 2, in the utility model five relatively independent main frame share service apparatuses 2 respectively by power lead, serial bus communication line and serial port data line be located at rack 1 on supply socket, serial bus concentrator and the IC card reader communication serial hub that can be connected with extraneous power supply, computing machine, IC card reader connect, realize that five main frame share service apparatuses work simultaneously.
Single main frame share service apparatus in the utility model, its principle of work is by IC card reader and computer input information and passes to central processing unit in the main frame share service device, by central processing unit this information is carried out recognition and verification, and the information after will confirming sends the tax-card device to, this central processing unit carries out conversion process and is sent to computing machine this information simultaneously, directly output.
In sum, main frame share service device in the utility model is by being provided with a plurality of relatively independent main frame share service apparatuses in a rack inside, and accommodate 16 or 26 tax-cards at each main frame share service apparatus, make the polylith tax-card in the rack to work simultaneously, thereby solved the problem of making out an invoice of the enterprise of generally paying taxes on a small scale, promptly realize controlling the polylith tax-card simultaneously with a computing machine, make the enterprise of generally paying taxes to carry out making out an invoice and managing of tax-supervise system by tax agency's mode, the realization main frame is shared, and solves medium-sized and small enterprises purchase tax-supervise system VAT invoice and opens the high problem of equipment cost.
