Described 2 pairs of infrared tubes are installed in respectively the infrared transmitting tube that is positioned at floor infrared tube frame 7 and sequential infrared tube frame 15 and the mounting hole 20,21 of adoptor.
The below take the infrared baffle plate of ground floor and the second layer to as example explanation floor location principle:
(1) hot outer baffle to be in the ground floor floor infrared baffle plate to the time (referring to Fig. 2-6):
In Fig. 2, Fig. 4 and Fig. 5, opened a rectangular opening 24 of confirming the ground floor floor information at the infrared baffle plate 9 of floor.This infrared baffle plate 9 is installed in ground floor.
When infrared tube when scanning infrared baffle plate to upper rectangular opening, infrared output signal is high level " 1 ", transmits when being blocked by infrared baffle plate when infrared, infrared output signal is low level " 0 ".When infrared tube to be scanned up to outside the right up and down two ends of infrared baffle plate local time, infrared output signal is high level " 1 ".
A1 among Fig. 6, B1 are respectively when car 5 moves from the top down infrared tube floor information pulse A1 and the clock pulse B1(that produces after to 2 through infrared baffle plate are seen from left to right in ground floor).
Sampling and the treating process of micro controller system are as follows:
1, car drops to Stall from second floor:
After elevator enters Stall from the 2nd buildings, micro controller system at first detects the output signal of floor infrared tube by highly low (infrared emission is blocked by the baffle plate upper end), namely become " 0 " (see the A1 among Fig. 6, see from left to right) by " 1 ", micro controller system confirms that thus elevator is operation downwards; In sampling process after this, micro controller system is further confirmed the clock pulse (B1 among Fig. 6, see from left to right) falling edge be sampling instant, micro controller system then gathers and is with 2 high level " 1 ", think that sampling effectively this moment, the level information that micro controller system continues at falling edge continuous acquisition to 5 a floor information rectangular opening of clock pulse is binary " 00001 " (seeing the A1 of Fig. 6), continuous acquisition to 2 high level " 1 " (seeing the A1 of Fig. 6) is affirmation sampling actv. information again at last, when elevator was parked in the ground floor floor, read-out showed that current floor is da " 1 ".
When 2, car upwards moves from one deck:
The sampling of micro controller system and treating process are discussed in following (two).
(2) hot outer baffle to be in the second layer floor infrared baffle plate to the time (referring to Fig. 7, Fig. 8):
In Fig. 7, opened its position of rectangular opening 25(of confirming second layer floor information at the infrared baffle plate 9 of floor and seen Fig. 7), this infrared baffle plate is installed in the second floor to 9.
When car 5 drops to the second layer and when coming to a complete stop, infrared tube is seen from left to right to waveform such as the A2 among Fig. 8, the B2(that scans from the 3rd layer), wherein A2 is the floor information pulse, B2 is clock pulse.
Sampling and the treating process of micro controller system are as follows:
1, car is down to second floor downstairs from three:
After elevator enters second floor from the 3rd buildings, the sampling process of micro controller system is the same with the sampling process of " car drops to Stall from second floor " in above-mentioned (), the level information of 5 floor information rectangular openings that micro controller system collects is binary " 00010 " (seeing the A2 among Fig. 8), and this moment, read-out showed that current floor is da " 2 ".
2, car rises to second floor from Stall:
When car 5 upwards moves to second floor and comes to a complete stop the position when stopping from the Stall position of coming to a complete stop, be positioned at infrared tube on the car walls is installed in ground floor to 1 at first from bottom to top scanning infrared baffle plate pair, when moving to second floor and stopping, infrared tube is to being positioned at the right below of infrared baffle plate of the second layer, that is to say, in this process, only scanned the infrared baffle plate pair of ground floor, and do not scanned the infrared baffle plate pair of the second layer.
When car begins to rise from the Stall position of coming to a complete stop, micro controller system at first detects the right output signal of sequential infrared tube and becomes low level by high level and namely become " 0 " (B1 among Fig. 6 by " 1 ", be installed in the clock pulse that the right infrared baffle plate of sequential of infrared baffle plate of Stall produces, and be the pulse of seeing from right to left), micro controller system confirms that thus elevator is upwards to move, in sampling process after this, micro controller system is further confirmed the clock pulse (B1 among Fig. 6, see from right to left) positive rise be sampling instant, micro controller system then collects 2 high level " 1 ", think that sampling effectively this moment, the level information that micro controller system continues at positive rise continuous acquisition to 5 a floor information rectangular opening of clock pulse is that binary " 10000 " (see the A1 among Fig. 6, see from right to left) continuous acquisition to 2 high level " 1 " (is seen the A1 among Fig. 6 again at last, see from right to left) for confirming sampling actv. information, when car when second floor comes to a complete stop, this moment, infrared tube was positioned at the infrared baffle plate of second floor pair to not collecting, so, at this moment the shown number of floor levels of read-out needs micro controller system further to be handled as follows: at first the floor level information " 10000 " of scanning is pronounced conversely and is " 00001 ", then be converted into da " 1 ", adding on this basis at last " 1 " is 1+1=2, and read-out shows that current number of floor levels is 2.
From the sampling of above-mentioned micro controller system and treating process as can be known, when cage descending moved, infrared tube was the right information of infrared baffle plate in the floor to display to what gather; When car rises operation, infrared tube is the right information of infrared baffle plate of lower one deck of floor to display to what gather, the processing that micro controller system at first will be read the binary code that gathers conversely, and then show again after the number of floor levels that obtains added one.
