Description
Technical field
The present invention relates to a kind ofly drag the control system of many The Design of Tax Controled Device based on one of ARM7 processor, a specifically a kind of PC can drag the control system of 28 The Design of Tax Controled Device.
Background technology
Tax agency mechanism is in the face of numerous medium and small sized enterprises, has that agency shop is many, the office space is little, operating personnel in short supply with problem such as PC equipment deficiency.At this problem, mainly contain following three kinds of solutions at present:
1, corresponding The Design of Tax Controled Device of PC, this scheme can cause the very big raising of cost, takies bigger working space simultaneously, so this scheme is infeasible.
2, a PC adopts the mode of plug to switch The Design of Tax Controled Device, but all The Design of Tax Controled Device all are mounted in the same wasting manpower and material resources of mode that rack inside is difficult for plug and plug, so this scheme is infeasible.
3, the serial port board on the purchase market, this scheme can cause the raising of cost, and stability is difficult to guarantee that serial port board need take the limited PCI slot resource of mainboard simultaneously, causes the waste of resource, so infeasible equally.
Summary of the invention
The purpose of this invention is to provide the control system that an a kind of PC drags a plurality of The Design of Tax Controled Device, can realize a kind of control system of dragging many The Design of Tax Controled Device based on one of ARM7 processor of peripheral hardwares such as shared PC of 28 tame enterprises and printer.
The objective of the invention is to realize in the following manner, system adopts the transmitting-receiving of switching that hardware platform that the LC4128V chip of the LPC2103 of the ARM7 of PHILIPS Co. kernel and Lattice builds and serial data Processing Algorithm realize The Design of Tax Controled Device, data and supports 28 The Design of Tax Controled Device to work simultaneously on a PC, this control system comprises a com port and 28 2 line serial ports, wherein com port connects PC, realizes communicating by letter of PC and control system mainboard; 28 2 line serial ports connect 28 The Design of Tax Controled Device, and other has 28 groups of pilot lamp to be used to refer to the The Design of Tax Controled Device of current gating respectively;
Its principle of work is as follows:
The mainboard of control system is connected with PC by a RS232 interface, CPU LPC2103 has two passages (UART), wherein UART1 links to each other with the RS232 interface of PC, monitoring is from control command and the tax-control data of PC, and UART2 is connected with CPLD, and CPLD connects the communication interface of 28 The Design of Tax Controled Device, control 28 LED lamps simultaneously, indicate the The Design of Tax Controled Device of work at present, CPU selects to be connected to The Design of Tax Controled Device on the CPLD by address wire, specifies the The Design of Tax Controled Device of numbering to carry out data interaction with PC;
The serial data Processing Algorithm is in the following ways:
PC sends the order of selecting the The Design of Tax Controled Device numbering, and CPU returns " ER " or " OK " information to PC after resolving, and PC judges the correctness that sends order according to return message.The numbering order that the PC of CPU parsing simultaneously sends is controlled CPLD and is carried out the passage switching, switches to the The Design of Tax Controled Device of current numbering;
PC sends tax-control data, after CPU is resolved to the data of 1B10 beginning, meet the tax control command format whole serial data of then packing, send to CPLD by UART2, CPLD is transmitted to The Design of Tax Controled Device, otherwise data buffer zero clearing, the return data of same The Design of Tax Controled Device is transmitted to CPU by CPLD, and CPU is uploaded to PC and handles, thereby realized the data interaction of PC and The Design of Tax Controled Device, reached the purpose of 28 The Design of Tax Controled Device of a PC control.
Excellent effect of the present invention is: a PC can drag the control system of a plurality of (28) The Design of Tax Controled Device, can realize peripheral hardwares such as shared PC of 28 tame enterprises and printer, thereby well solve the difficult problem that tax agency mechanism exists.Has the saving resource, advantage such as cost is low and workable.
Description of drawings
Fig. 1 drags many The Design of Tax Controled Device control system structural representation;
Specifically execute mode
With reference to accompanying drawing system of the present invention is done following detailed description the in detail:
The present invention adopts hardware platform that the LC4128V chip of the LPC2103 of ARM7 kernel and Lattice builds and serial data Processing Algorithm to realize that 28 The Design of Tax Controled Device work simultaneously on a PC.
As shown in drawings, the mainboard of control system is connected with PC by a RS232 interface, and CPU LPC2103 has two passages (UART), and wherein UART1 links to each other with the RS232 interface of PC, monitors control command and tax-control data from PC.UART2 is connected with CPLD, and CPLD connects the communication interface of 28 The Design of Tax Controled Device, controls 28 LED lamps simultaneously, indicates the The Design of Tax Controled Device of work at present.CPU selects to be connected to The Design of Tax Controled Device on the CPLD by address wire, specifies the The Design of Tax Controled Device of numbering to carry out data interaction with PC.
The serial data Processing Algorithm is in the following ways:
If PC sends the order of selecting the The Design of Tax Controled Device numbering, CPU returns " ER " or " OK " information to PC after resolving, and PC judges the correctness that sends order according to return message.The numbering order that the PC of CPU parsing simultaneously sends is controlled CPLD and is carried out the passage switching, switches to the The Design of Tax Controled Device of current numbering.
If PC sends tax-control data, after CPU is resolved to the data of 1B10 beginning,, send to CPLD by UART2 if meet the tax control command format whole serial data of then packing, CPLD is transmitted to The Design of Tax Controled Device, otherwise the data buffer zero clearing.The return data of same The Design of Tax Controled Device, CPLD is transmitted to CPU, and CPU is uploaded to PC and handles.Thereby realized the data interaction of PC and The Design of Tax Controled Device, reached the purpose of 28 The Design of Tax Controled Device of a PC control.
