Shown in Figure 3 is the main flow chart of this blocking fender guard.It has used external interrupt 0, external interrupt 1 and 0 three interruptions of timer internal.Wherein external interrupt mainly receives out (pass) door direction pulse signal, at first is provided with in the beginning of program and wherein breaks port address, and be set to the falling edge triggering mode, and the width of pulse is handled in the interruption entry address that timer internal is set simultaneously.Then system opens wait the signal input of (pass) door, when instructing if any opening the door, system will be transferred to the instruction output of opening the door, the instruction of closing the door is simultaneously exported, and forbid that the time interrupts and external interrupt, as the nothing input instruction that opens the door, whether then system will inquire about has the gate signal of reopening to be activated, as reopen door and be activated then the also output instruction of opening the door, and forbid that the time interrupts and external interrupt, when output command is opened the door in execution, whether system will continue inquiry and open the door and put in place, do not put in place and continue to open the door instruction output, as whether the system of putting in place of opening the door is regardless of having the door of a reopening mark all to be eliminated, and the input that (pass) door instructs is opened in inquiry again.
As both there not being the instruction of opening the door, do not have again under the door of the reopening information state, the instruction input of whether closing the door will be inquired about by system, as close the door instruction input of nothing, (closing the door) instruction of then forbidding opening the door is exported, external interrupt and timer internal also are closed simultaneously, and certification mark is reset, and system continues the input that the instruction of (pass) door is opened in inquiry then: as both there not being the instruction of opening the door, do not have again under the door of the reopening information state, close the door when input instruction, system opens the door inquiry and puts in place and door-closing in-place, as in the zone that puts in place, system then closes external interrupt and timer internal, and the reset detection mark, export the instruction of closing the door, continue to get back to the input whether inquiry of program starting point has out the instruction of (pass) door then; As both there not being the instruction of opening the door, do not have again under the door of the reopening information state, when closing the door the instruction input, open-door system is in both not open the door and puts in place, door-closing in-place not again, illustrate that open-door system should be in the state of closing the door, at this moment, program will start external interrupt and timer internal, and the initial value of assignment timer, put certification mark simultaneously, as there is not the direction of opening the door pulse input in this stage, and the direction of closing the door pulse width meets the setting-up time requirement, and then program will be got back to input that the instruction of (pass) door is opened in starting point continuation inquiry, repeat said process.
Fig. 4 is the interrupt routine diagram of circuit of direction step-by-step counting of closing the door; when closing the door the direction pulse signal input; external interrupt 1 is activated; program enters interrupt handling and keeps the scene intact at this moment; paired pulses is counted; when the pulse of counting is carried out again assignment (the size decision pulse width size of this setting value to inner timer parameter during more than or equal to setting value; the big more pulse width that then requires of setting value is more little; be that the open-door system running velocity is fast more; otherwise require pulse wide more; after being set at 5 pulses in this flow process timer parameter is reset), as then not recovering on-the-spot, wait for next the interruption again to setting value.
Fig. 5 is the interrupt routine diagram of circuit of timer internal; when the time interrupts producing; at first keep the scene intact and the initial value of timer is reset; whether the time that inquiry is simultaneously set puts in place, and to setting value (impulse singla of the direction of promptly closing the door fail at the appointed time to count down to setting value), then interrupt routine is exported the shutoff instruction of closing the door as; export the instruction of opening the door; put the reopening gate signal simultaneously, and the recovery scene returns interruption, reenter and reopen the door operation.Do not arrive as the time set value, then maintain the original state and interruption is returned at the scene of recovering.
Fig. 6 is the interrupt routine diagram of circuit of direction pulse of opening the door; when enabling nulse triggers external interrupt, at first keep the scene intact, enter interrupt handling; when certification mark is not activated; then recover on-the-spot, withdraw from interruption, be activated as certification mark on the contrary; then system thinks that the open-door system blocking promptly puts the reopening gate signal; the output command of closing the door simultaneously, the instruction of opening the door, and interruption is withdrawed from the recovery scene.
By in Fig. 2 electrical schematic diagram as seen, IC7, IC8 form set of pulses change-over circuit, it changes A, the red switch of B phase time serial vein of the rotary encoder generation of motor rear end into directed output two impulse singlas (direction of promptly the opening the door pulse and the direction pulse of closing the door), and export to micro controller system through the IC6 photoelectrical coupler, because the impulse rate after the conversion is directly proportional with the motor running velocity, this pulsing operation direction is relevant simultaneously, and the signal source that therefore can be used as the detection of pulse direction and pulsewidth is employed in program.
When apparatus for controlling elevator device input enabling signal (COM and OPI connect); relay J 2 adhesives; by the J2 contact with micro controller system P3.1 mouth drop-down be low level; in a single day micro controller system detects this signal and confirms that promptly enabling signal imports; according to main program flow chart; the output command of closing the door when enabling signal is transfused to is cut, and fender guard output is simultaneously opened the door to instruct and given subordinate's speed regulation device and close trace routine.When gate signal is closed in the interface input (COM and CLI connect); relay J 1 adhesive; simultaneously; by the J1 contact with micro controller system P3.0 mouth drop-down be low level; P3.1 still is a low level as this moment; according to main program flow chart; the handler that opens the door is preferential; therefore; still carry out the instruction of opening the door, have only when P3.1 be the just execution dependent program of closing the door of high level when not being transfused to (be outside enabling signal), when door leaf puts in place or during door-closing in-place opening the door; trace routine is not activated; have only ability start detection program in the zone of a door leaf that machine drove in the process of closing the door, i.e. opening time timer and external interrupt are when trace routine does not detect the blocking signal; subordinate's speed regulation device is given in the instruction of closing the door of the fender guard output command that opens the door, output simultaneously.Only fender guard is just carried out the reopening gate signal under following two kinds of situations:
1, the door machine can be received in the same way the pulse of (direction of closing the door) according to the running velocity micro controller system in the process of closing the door
Signal, when the door leaf that is driven when the door machine is run into obstacle, according to the antagonistic force principle, this moment door leaf
Can rebound in moment, this bounce-back process detects promptly once the rotary encoder that is installed in motor rear end
By pulse switching circuit, to a string oppositely impulse singla of (direction of opening the door) of micro controller system input, should
Signal is by the external interrupt routine processes; promptly confirm as a machine blocking; this moment, fender guard disconnected the output command of closing the door immediately; output is opened the door instruction to subordinate's governor; produce simultaneously and reopen gate signal; the execution operation procedure that opens the door is reopened gate signal and just can be cancelled when opening the door, carry out the instruction of closing the door once more.2; the door machine is in the operational process of closing the door; by motor rear end A; the pass door pulse signal that the pulse of B phase is changed; the actual speed of fellow disciple's machine operation is directly proportional; when its width of impulse singla that micro controller system is accepted is prescribed a time limit above the following of setting; be that free interrupt routine is handled; confirming as a motor speed descends; decision gate machine blocking thus; this moment, fender guard disconnected the output command of closing the door immediately; output is opened the door instruction to subordinate's governor, produces simultaneously to reopen gate signal, carries out the operation procedure that opens the door; when opening the door, reopen gate signal and just can be cancelled, carry out the instruction of closing the door once more.
