The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1 shows a flow chart of an elevator leveling method. ' Qiyi
Step a, learning floor data F (i), the length A of the magnetic isolation plate and the distance B between the upper leveling switch and the lower leveling switch, wherein i corresponds to a representative floor and takes values from 1 to a total floor K, F (1) represents the floor data between the bottommost floor and the next bottom floor, and F (K) represents the floor data between the next highest floor and the highest floor.
Please refer to fig. 2.
Elevator control systems are typically configured with 2 leveling switches, an upper leveling switch, and a lower leveling switch. And in the range of the magnetism isolating plate, the leveling switch signal is valid, when the leveling switch is separated from the range of the magnetism isolating plate, the leveling switch signal is invalid, wherein the length of the magnetism isolating plate is A, the distance between the upper leveling switch and the lower leveling switch is B, and when the middle points of the two leveling switches coincide with the middle point of the magnetism isolating plate, the elevator is in the leveling position.
Before the elevator is put into normal operation, the elevator floor data F (i), the length A of the magnetic isolation plate and the distance B between the upper leveling switch and the lower leveling switch can be automatically learned. K represents floor data, F (0) is equal to 0, F (1) represents floor data between the bottommost floor and the second bottom floor, and so on.
And step b, when the elevator runs, the elevator runs from the current floor to the upper floor or the lower floor, and the leveling switch is effective, recording the current position information PK 1.
In one embodiment, when the elevator normally goes upwards and runs from the 1-floor level to the 2-floor level, the upper-floor switch and the lower-floor switch are sequentially separated from the 1-floor level flashboard area. When the elevator arrives at the 2-floor landing position, the upward landing switch is effective when encountering the magnetic isolation plate, the elevator firstly records the current elevator position P1, and the position information is generally obtained by accumulating encoder signals of an elevator motor shaft. And the current position information PK1 of all floors is obtained by analogy.
And c, acquiring corrected position information PK2 of the current position according to the learned floor data F (i), the length A of the magnetic isolation plate and the distance B between the upper leveling switch and the lower leveling switch.
The elevator running direction comprises an ascending direction and a descending direction, so that when the elevator runs upwards, the machine acquires corrected position information PK2 of the current position information according to the learned floor data and the A switch distance B, and the values of the corrected position information PK2 are F (i-1) - (A/2+ B/2). When the elevator goes down, according to the learned floor data and the A switch distance B, the machine acquires the corrected position information PK2 of the current position information, wherein the value is F (i-1) + (A/2+ B/2).
Specifically, the step c includes:
when the elevator ascends, acquiring corrected position information PK2 of the current position, which is F (i-1) - (A/2+ B/2), according to the learned floor data F (i), the length A of the magnetic isolation plate and the distance B between the upper leveling switch and the lower leveling switch;
when the elevator descends, the corrected position information PK2 of the current position is obtained according to the learned floor data F (i), the length A of the magnetic isolation plate and the distance B between the upper leveling switch and the lower leveling switch, wherein F (i-1) + (A/2+ B/2).
Step d, when the current floor needs to be parked, if the position information of the elevator is in PK1-S and the leveling switch is always effective, the leveling signal is considered to be effective, and the elevator is controlled to park by taking PK2 as the current position information; and if the position information of the elevator is not within PK1-S and the leveling switch is always effective, the leveling signal is considered as an interference signal, and the elevator is controlled to stop by taking PK1 as the current position information, wherein S is a first set distance threshold value.
The step d comprises the following steps:
when the elevator goes upward and needs to be stopped at the current floor, the first set distance threshold value S is PK1+ S1, if the position information of the elevator is within PK 1-PK 1+ S1 and an upper leveling switch is always effective, the upper leveling signal is considered to be effective, and the elevator is controlled to stop by taking PK2 as the current position information; if the position information of the elevator is not in PK 1-PK 1+ S1 and the upper leveling switch is always effective, the upper leveling signal is considered as an interference signal, and the elevator is controlled to stop by taking PK1 as the current position information;
when the elevator descends and the current floor needs to be stopped, a first set distance threshold value S is PK1-S1, if the position information of the elevator is in PK 1-PK 1-S1 and a lower leveling switch is always effective, the lower leveling signal is considered to be effective, and the elevator is controlled to stop by taking PK2 as the current position information; and if the position information of the elevator is not in PK 1-PK 1-S1 and the lower leveling switch is always effective, the lower leveling signal is considered as an interference signal, and the elevator is controlled to stop by taking PK1 as the current position information, wherein S1 is equal to (A/2+ B/2)/2.
Step e, when the elevator parks at a floor other than the current floor, if the position information of the elevator is in PK 1-S' and the leveling switch is always effective, the leveling signal is considered to be effective, and the elevator is controlled to park by taking PK2 as the current position information; and if the position information of the elevator is not in PK1-S 'and the leveling switch is always effective, the leveling signal is considered as an interference signal, and the elevator is controlled to stop by taking PK1 as the current position information, wherein S' is a second set distance threshold value.
The step e comprises the following steps:
when the elevator goes upward and stops at a floor outside the current floor, the second set distance threshold value S' is PK1+ S2, if the position information of the elevator is in PK 1-PK 1+ S2 and the upper leveling switch is always effective, the upper leveling signal is considered to be effective, and the elevator is controlled to stop by taking PK2 as the current position information; if the position information of the elevator is not in PK 1-PK 1+ S2 and the upper leveling switch is always effective, the upper leveling signal is considered as an interference signal, and the elevator is controlled to stop by taking PK1 as the current position information;
when the elevator descends and stops at a floor outside the current floor, the second set distance threshold value S' is PK1-S2, if the position information of the elevator is in PK 1-PK 1-S2, the lower leveling switch is always effective, the lower leveling signal is considered to be effective, and the elevator is controlled to stop by taking PK2 as the current position information; and if the position information of the elevator is not in PK 1-PK 1-S2 and the lower leveling switch is always effective, the lower leveling signal is considered as an interference signal, and the elevator is controlled to stop by taking PK1 as the current position information, wherein S2 is A/2.
In the method, the PK1 position information is adopted for accumulation to obtain the current position information, and meanwhile, the corresponding corrected position information PK2 is continuously obtained. Therefore, the elevator leveling can be based on PK1 or PK2, and when one signal is wrong, the other is normal according to the judgment result. Thus, the accuracy of elevator leveling can be improved.
When the elevator is normally operated, if the elevator stops at the current floor, the effective distance of the upper/lower leveling signal is normally (A/2+ B/2). If the elevator stops at a floor other than the front, the effective distance of the up/down leveling signal is a length.
The method determines the leveling basis by judging the effective range of the leveling signal, and similarly, the leveling basis can be determined by the effective time of the leveling signal. The method comprises the following specific steps:
the elevator leveling processing method further comprises the following steps:
when the current floor needs to be parked, if the effective time of the leveling signal is within T0-T1, the leveling signal is considered to be effective, and the elevator is controlled to park by taking PK2 as the current position information; if the position information of the elevator is not within T0-T1, the leveling signal is considered as an interference signal, and the elevator is controlled to stop by taking PK1 as the current position information;
when the elevator parks at a floor other than the current floor, if the effective time of the leveling signal is within T0-T2, the leveling signal is considered to be effective, and the elevator is controlled to park by taking PK2 as the current position information; and if the effective time of the leveling signal is not within T0-T2, the leveling signal is considered as an interference signal, and the elevator is controlled to stop by taking PK1 as the current position information, wherein T0, T1 and T2 are set time thresholds.
By adopting the method, the signal jitter phenomenon of the leveling signal can be ensured when the leveling signal of the elevator changes or after the leveling switch is separated from the leveling plugboard in the starting process of the elevator. Or the elevator position can not be influenced under the conditions of transient interference phenomenon of the leveling signal and the like.
