Fig. 2 is the utility model integrated circuit control timing figure.
CLK is that clock signal, Reset are that reset signal, CSN are that chip selection signal, ModSel are that model selection, LE are that latch signal, OC/EN are that latch output, PData are I/O output for allowing output, SData.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further:
As shown in Figure 1, it comprises: a host computer 1 is PC, host computer 1 carries out the signal transmission with single-chip microcomputer 2 by the mode of serial communication, single-chip microcomputer 2 receives the control signal of host computer 1, and control signal received, agreement between host computer 1 and the single-chip microcomputer 2 is: according to the quantity of measured object, the arrangement mode coordinates computed value with row X row defines as variable with row-coordinate axle value, row coordinate figure, switching signal.In the present embodiment, measurand is made as 168 OLED display screens, and then horizontal ordinate represents to have 6 positions respectively with hexadecimal A, B, C, D, E, F, is ordinate with 01? 8 expressions have 28 positions, the switch situation of relay is represented closure with 1, and 0 expression disconnects.As want first row, the first row relay closes then host computer 1 just " 0A 0101 " control signal is sent to single-chip microcomputer 2, return again after single-chip microcomputer 2 receives and give host computer 1, after treating that host computer 1 sends the affirmation answer, single-chip microcomputer 2 is decoded control signal according to agreement, and decoded data are passed to shift register 3.
As shown in Figure 2, at first the Reset (reset signal) with shift register 3 puts 1, shift register 3 is resetted, in the present embodiment, measured object is 168, then the value of 168 bit registers all is 0 earlier, when the data accompanying clock CLK of single-chip microcomputer 2 signal is imported, 168 of data are shifted by shift register 3, behind 168 clock CLK signals, after promptly 168 control signals of decoding by single-chip microcomputer 2 are shifted fully and finish, export 4 ports by I/O and export to relay 7, make the 7 closed or disconnections of corresponding relay, simultaneously, single-chip microcomputer 2 is controlled latch signal LE is put 1, latch 5 is latched data mode, up to the host computer arrival of control command next time.
I/O exports the data of 4 ports, be earlier controls the break-make of corresponding relays after the conversion, amplification by driving circuit 6 again.
Because host computer and single-chip microcomputer adopt succinct control protocol, make control simple and reliable, shift register and I/O output port have replaced equipment such as switch box, switch rack, make detection control more flexible.
