Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a fundamental diagram of the present utility model.

Fig. 2 is a logic glue block scheme of the present utility model.

Fig. 3 is a kind of physical circuit schematic diagram of accompanying drawing 2 of the present utility model.

As shown in Figure 1.Microcomputer color measurement and color match device is the color measurement and color match problem that is used for solving dyeing course, finishes the design effort of dye formulation.The utility model preferably adopts JFY-AB1 type concave grating colour photometer as the colorimetric parameter detecting device, and colour photometer is better than spectrophotometric function like this, be can test sample comprehensive colorimetric parameter.It is that the D65 standard sources is shone sample by integrating sphere, by sample reflection by the shed continuous monochromatic spectrum of 400-700nm wavelength of the monochromatic instrument of spectrum, make light signal transfer electric signal to by receiving element, circuit and interface circuit carry out the A/D conversion after tested, make simulating signal become digital signal, parallel interface through hardware cooperates with software interface, adopt interrupt mode to be input to data in the microcomputer automatically, and then by microcomputer under the support of special use color matching application software that this device is equipped with, finish the compound design work of dyestuff.By microcomputer design dye formulation is through after the color matching specific program Automatic Optimal of this device, offers the user's with the index that requires of least cost and minimum aberration.The implementation step of above-mentioned whole process is the whole operating process that replace manually finishing automatic color measurement and color match with microcomputer.

Online between colour photometer and the microcomputer realized that by hardware interface circuit it mainly is at JFY-AB1 type colour photometer and IBMPC series mini computer interconnection, carries out data and transmit and design.As shown in Figure 2, the logical circuit of this interface mainly comprises, latch.The I/O parallel controller, interrupt control logic, data buffer, I/O controller, I/O address code translator etc.This device adopts the STD bus structure.As shown in Figure 3, outer lines all among the figure are except that the signal by the colour photometer input, all be to link to each other with the CPUI/O bus of computing machine, its advantage is, no matter be the original-pack computing machine of IBMPC or be non-original-assemblied machine, as long as adopt the microcomputer of IBMPC serial bus structure can be suitable for this interface circuit, this has just enlarged the scope of application of this interface.

As shown in Figure 3, it is the practical principle figure of interface circuit, and the bracket content among the figure is meant the lead-foot-line of CPUI/O bus, and A represents component side, and B represents the bonding wire face, and its concrete numeral indicates corresponding lead-in wire sequence number.Constitute the I/O address code translator by A7-A2 address signal and resistor chain Rn, toggle switch Kn and NOR gate circuit 3.After the selected dial-up of user is provided with, when as long as the signal value of address wire A7-A2 meets the dial-up state, be output as high level signal through NOR gate circuit 3, have only when the output of 6 NOR gate circuits 3 all is high level, link to each other with the chip select signal CS pin of I/O parallel controller control chip through not circuit 2 again, operation is chosen in realization, address signal line A1 and A2 through the integrated circuit LS125 of I/O controller be connected to the A1 of I/O parallel controller control chip and A0 pin with chip select signal CS in order to select PA, the data channel of PB and PC, when chip select signal CS is effective, if CPU sends read command, when IOR is effective, this signal makes the RD signal effective its integrated circuit 8255 that sends the I/O parallel controller to by the integrated circuit LS125 of I/O controller, bidirectional data buffer circuit LS245 to the data impact damper controls simultaneously, so just with the data on the reading port of the integrated circuit 8255 of I/O parallel controller, LS245 is read into D7-D0 on the data bus by the bidirectional data buffer circuit; It is same when CPU sends write order, when IOW is effective, data D7-D0 on the data bus finishes CPU to the state of I/O parallel controller and the setting of order through the FPDP that bidirectional data buffer circuit LS245 enters into integrated circuit 8255.The PA of integrated circuit 8255 parallel interface control chips and PB passage, the integrated circuit LS244 by latch links to each other with the data-signal of JFY-AB1 type colour photometer.Link to each other with IRQ3,7 ends of I/O bus by interrupt control logic circuit and parallel controller pin PC5 in addition, interrupt control logic circuit PC4 links to each other with interrupt request singal STB end through tri-state gate circuit 4, interrupt control logic circuit and link to each other with the Enable Pin of integrated circuit LS244 with parallel controller pin PC3 has constituted the interrupt control logic circuit like this.If adopt interrupt mode, after CPU sends the software control order, the PA passage of control chip adopts and interrupts input mode, and when the PB passage adopts unconditional input mode, if it is effective from the interrupt request singal STB of colour photometer, represent that promptly colour photometer has data-signal to transmit to microcomputer, interrupt request singal STB imports it into integrated circuit 8255 by interrupt control logic circuit and parallel controller pin PC4 through tri-state gate circuit 4, pass through the IRQ3 of I/O bus again by interrupt control logic circuit and parallel controller pin PC5,7 ends, notice CPU waits pending.When CPU carries out break in service, respectively the PA of control chip and the data of PB passage are sent into calculator memory, and the cancellation interrupt request singal, finish break in service.If adopt the inquiry mode input, at first the I/O parallel controller is sent unconditional input mode by CPU, CPU also reads the data of interrupt control circuit pc port repeatedly, as the interrupt control logic circuit that reads in and parallel controller pin PC4 during for " 1 ", data on the expression colour photometer are that effectively at this moment CPU then is read into the PA of control chip and the data of PB passage in the microcomputer.

Because this interface circuit and software control order are used, promptly can adopt the interrupt control mode to this interface circuit, the data-signal of colour photometer is sent in the microcomputer, can utilize inquiry mode again, finish the transmission work of data-signal.
