The electronic warp knitting machine course of work of present embodiment is as follows: behind the complete machine powering, at first the control of the corresponding Jacquard comb of operation drives main program on industrial computer 1, open corresponding colored shape file and will spend shape file to convert binary file to by this main program, colored shape download subprogram control industrial computer 1 by the operation main program transfers to control box 2 with binary system flower shape file by the RS-232C interface again, by control box 2 binary system flower shape file data flow is transferred to a RS-422 interface of the relay plate 32 that is numbered first driving box 3 of 01 again by the RS-422 interface, 32 of the relay plates of first driving box 3 begin successively backward by its 2nd RS-422 interface, and the relay plate 32 of a driving box 3 sends data, and the flower graphic data adopts the form of step-by-step excitation to transmit by the RS-422 interface between the relay plate 32 of each driving box 3, promptly export first driving box 3 signal to by control box 2, undertaken sending second driving box 3 after the hardware excitation by 32 pairs of signals of the relay plate in first driving box 3, by that analogy driving box 3 to the last.Because the distance between each driving box 3 of native system is all very near, the transmission mechanism of step-by-step excitation makes system on the basis of original strong jamproof differential type twisted-pair feeder physical transfer mechanism in addition, and reliability is further strengthened.
The relay plate 32 of each driving box 3 is when spending graphic data to download, the OE of each RS-422 interface, STB, CLK, Dout port all are configured to high level, the CLK port is put low and is notified each slave computer to enter jacquard weave data downloading mode, after the download of view picture jacquard weave data was finished, the CLK port just can be pulled high level.
After the flower graphic data is downloaded on the memory of relay plate 32 of each driving box 3 successively, control box 2 passes through the RS-422 interface with initial jacquard weave position, finish the jacquard weave position, fabric width, panel height, the speed of service, information configuration such as jacquard weave data pattern are proper, whole Jacquard comb control-driven system enters the jacquard weave armed state, certain main shaft inductor 41 on being installed in main frame 0 main shaft is triggered and when control box 2 sends transducing signals, control box 2 sends a control command to first coupled driving box 3, undertaken being sent to second driving box 3 after the hardware excitation by 32 pairs of control commands of the relay plate in first driving box 3 again, by that analogy the relay plate 32 of a driving box 3 to the last.Control box 2 is behind the transducing signal that receives certain main shaft inductor 41, and to the relay plate 32 transmission control commands of first driving box 3, control command is sent to the driving box 3 of next cascade successively, until bus termination device 42.Each each drive plate 33 of relay plate 32 controls drives corresponding piezoelectric ceramics Jacquard comb and carries out jacquard weave work.
Be one from 1 to 0 saltus step of the Dout port on the RS-422 interface of control box 2, represent each relay plate 32 beginning to 12 drive plate 33(24 of its administration comb) send the jacquard weave signal.At this moment, each relay plate 32 its Dout is set to the Din of the corresponding host computer of 0() and 12 drive plates 33 that begin in cabinet send the jacquard weave signals, after the jacquard weave data were sent completely, the Dout signal of this relay plate was set to 1; After all cabinets were all finished the jacquard weave transfer of data, the Din signal on the control box 2 transferred return visit to 1, illustrated that all jacquard weave data are all on board.Control box 2 just can send the STB signal and notifies all drive plates 33 that data are latched into output interface then, last control box 2 sends the OE signal, make whole comb sheets complete frame jacquard weave signal of output synchronously, the action of control system jacquard weave, control box 2 is that 1 signal of finishing a frame is exported with the Dout home position signal afterwards.When next Dout signal from 1 to 0 saltus step; relay plate 32 in the slave computer will increase one automatically; the jacquard weave signal of next frame is sent; and under the control of Din, STB, OE signal, drive the jacquard weave signal output that the Jacquard comb is finished next frame, by that analogy; after the whole jacquard weave signals on the relay plate 32 are finished output; to return first frame of jacquard weave data automatically, restart circulation output, send halt instruction up to system-down or by the RS-422 interface till.
The inverse signal of each relay plate 32 all is to carry out the signal that logic merges by the inverse signal of internal logic generation with from the inverse signal that the relay plate 32 of back cascade is uploaded.This just means that when all relay plates 32 of system's cascade did not all have return data, system returned bus and is in idle state (high level); When any one relay plate 32 in the cascade had return data, these data can be realized relay function by the upper industrial computer 1(of being transmitted to of several relay plate 32 one-level one-levels of its front end); When one in the cascade above relay plate 32 has return data simultaneously, chaotic mistake will take place in system data.Therefore, this state is collected the return data of each relay plate 32 one by one in case generation is carried out point-to-point operation with regard to the upper industrial computer machine of needs.
