The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is done further description.
See figures.1.and.2, the present invention includes CAN (controller local area network) drive circuit, single-chip microcomputer PIC and at least one motor-drive circuit.
Single-chip microcomputer PIC of the present invention connects the CAN bus through the CAN drive circuit, the upper control machine that acceptance is connected with the CAN bus and the driving command of control operation platform, and feed back black key opening information simultaneously.
In the present invention, each black key opening controller can be controlled 20 black key apertures of each ink fountain usually, to guarantee the quantity of ink reasonable distribution of the different ink-covered areas of each ink fountain.Present embodiment is provided with 20 motor-drive circuits, i.e. motor-drive circuit 1 to motor-drive circuit 20, and this motor-drive circuit 1～20 end separately connects single-chip microcomputer PIC respectively, and the other end connects black key adjuster 1～20 respectively.
With reference to Fig. 3, in circuit, CAN drive circuit of the present invention comprises CAN transceiver U22 and two photoelectrical coupler U20 and U21.Serial data output bus TXD on the CAN transceiver U22 is connected with the output of photoelectrical coupler U21, and the serial data input bus RXD on the CAN transceiver U22 is connected with the input of another photoelectrical coupler U20.The CAN drive circuit has adopted provides difference to send driving force and to the differential driving ability to accept to bus signals, and its major function is that the logic level transition with the CAN transceiver is the differential level of CAN bus, to guarantee CAN bus node safety.
The transfer of data of CAN transceiver Transmitting and Receiving End RXD, TXD adopts the isolation method of photoelectrical coupler U20 and U21 can reach level match and reduces the purpose that each node disturbs network electric power on the bus network.
