Display 22 links to each other with above-mentioned CPU 20, receives its control signal and shows corresponding status information.
Overload detection 23 links to each other with above-mentioned CPU 20, when the input paper of above-mentioned shredded paper mechanical device is too much, can show corresponding " overload " information with control display 22 for above-mentioned CPU by input control signal.
Going into paper detector 21 links to each other with above-mentioned CPU 20, enter the inlet of above-mentioned shredded paper mechanical device when paper, detector can input control signal be given the motor driver 28 of above-mentioned CPU 20 to start above-mentioned shredded paper mechanical device, status information that display 22 shows is corresponding " paper feed/move back paper ".
Motor temperature detector 26 links to each other with above-mentioned CPU 20, when the drive motors of above-mentioned shredded paper mechanical device is overheated, can show the information of corresponding motor " overheated " for the control display above-mentioned CPU 20 by input control signal.
Door is driven detector 24 and is linked to each other with above-mentioned CPU 20, when the door of above-mentioned shredded paper mechanical device is opened, can show the information of corresponding " door is held " for control display 22 above-mentioned CPU 20 by input control signal.
The full detector 25 of paper links to each other with above-mentioned CPU 20, when the shredded paper of above-mentioned shredded paper mechanical device is expired, the detector that is arranged on the shredded paper paper magazine of shredded paper mechanical device can detect this state, thereby input control signal shows the information of corresponding shredded paper " paper is full " for above-mentioned CPU 20 with control display 22.
Fig. 3 is the circuit diagram of shredder of the present invention.AC power is added to the elementary of transformer by fuse one tunnel, another road is added on the motor 27, the rectification circuit rectification that the alternating voltage that the elementary output of transformer is 19 volts is formed through D1, D2, D3, D4 diode, the DC voltage that obtains 24 volts is supplied with on the relay 302, other circuit is supplied with by the three terminal regulator voltage stabilizing in another road.
Door is driven detector 24 and is adopted a magnetic reed switch 303, referring to Fig. 4, when door was opened, this magnetic reed switch disconnected, the output output low level, this low level is input to " 3 " pin of the interface control circuit 301 of CPU 20, this low level is added to CPU 20, and CPU 20 input control signals are given display 22, and this display adopts LCD, so can show " door is opened " icon on the screen of LCD, and forbid the drive motors forward or reverse.Otherwise, do not show, thereby, the user reminded.
Referring to Fig. 3 and Fig. 5, when motor overheating, the temperature detect switch (TDS) 310 of motor internal disconnects, " 7 " pin output low level of interface control circuit 301, this level is added to CPU 20 input control signals and gives LCD 22, display shows " overheated " icon, and forbids the drive motors forward or reverse.Otherwise, do not show, can remind the user.
Referring to Fig. 3 and Fig. 6, when paper is full, full detector 25 infrared detection units of paper can make gauge tap 311 output high level give interface control circuit 301 " 6 " pin, output low level, this level is added to CPU 20 input control signals and gives LCD 22, display shows " paper is full " icon, and forbids the drive motors forward or reverse.Otherwise, do not show, can remind the user.
Referring to Fig. 3 and Fig. 7, overload detection 23 is made up of overload sample resistance R14, comparator IC 3, capacitor C 4, resistance R 9, R8, R10 and comparative voltage adjuster VR1.Have two actions behind the motor overload, at first, overload back motor reversed for 2 seconds, claimed this moment " overload 1 ", whether reverse after 2 seconds, detecting paper inlet has paper, if paper is arranged then motor was just changeing for 2 seconds again, claim " overload 2 " this moment, if no paper then motor does not carry out any action.
When overload, at first whether detection machine at overload 1, if at overload 1 then LCD 22 shows counter-rotating and overload icon, the while motor reverses and machine state is set is overload 2, reverse 2 second time to after detect current state again, whether if be overload 2, then continue detecting has paper, at this moment, " 3 " pin voltage of IC3 is higher than " 2 " pin, and " 1 " pin of IC3 is exported high level at this moment, if paper is arranged then motor was just changeing 2 seconds, if there is not paper, then detects and finish.Described level is added to CPU 20 input control signals and gives LCD display 22, its " 18 " pin is imported " 2 " pin that a low level is given interface control circuit 301 simultaneously, and this level is added to Q1, and relay 1 disconnects, motor is just changeing and is stopping, 0.5 after second, " 17 " pin output high level, Q2 conducting, relay 2 adhesives, the motor counter-rotating, machine moves back paper, controls LCD simultaneously and does corresponding " moving back paper " demonstration.
Referring to Fig. 3 and Fig. 8, whether at first judge motor at holding state, if at non-holding state motor forbid just changeing.If at holding state, check whether paper inlet has paper, if paper is arranged then continue to judge whether the machine overload, if during the machine overload then enter the overload resume module, if do not transship then motor just changes.When going into paper, infrared gauge tap 312 output low levels of going into paper detector 21 are given " 5 " pin of interface control circuit 301, output low level, this level are added to CPU 20 input control signals and give LCD display 22, and display shows " paper feed " icon, import a high level simultaneously and give " 2 " pin of interface control circuit 301, this level is added to Q1, makes the Q1 conducting, relay 1 adhesive, motor just changes, the machine shredded paper.Otherwise, do not show, and do not work.
Fig. 9 is the schematic diagram that circuit shown in Figure 3 adopts integrated circuit.In this embodiment, CPU 20 adopts eight LCD types of HT49R50A single-chip microcomputer of HOLTEK.Its principle is well known to those skilled in the art, just no longer introduces here.
Do not limit protection scope of the present invention in the above-mentioned enforcement.Essence of the present invention is to show the shredder motor overheating, go into paper and too much reach irregular working situations such as shredded paper hutch shredded paper is too much by the display device, can increase the security that shredder uses.
