Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an elevator floor fault correcting method according to a first embodiment of the present invention, where the present embodiment is applicable to a situation of elevator floor fault correcting, and the method may be executed by an elevator floor fault correcting device, and the device may be implemented by hardware and/or software, and specifically includes the following steps:
and 110, acquiring the measured initial floor height data when the elevator car is in an unexpected emergency stop in the running state.
Wherein, fig. 2 is a schematic structural diagram of an elevator provided in a first embodiment of the present invention, as shown in fig. 2, an elevator 150 includes: the hoistway 151, the elevator car 152 located in the hoistway 151, landing doors 153, the magnetic isolation plate 154, the leveling sensor 155, the signal transmitting and receiving device 156, the signal reflecting device 157, and the magnetic isolation plate 154 of the motor (not shown in fig. 2) with a motor rotary encoder can be mounted on the wall of the hoistway 151, or can be mounted on a support of a guide rail or a guide rail of the elevator, when the leveling sensor 155 senses the magnetic isolation plate 154 of a corresponding floor, it can be determined that the elevator car 152 is located at the leveling position of the floor, and at this time, the elevator car just corresponds to the landing door 153 of the floor.
Specifically, the motor rotary encoder in the motor outputs pulses when rotating, the position of the motor rotary encoder is known through the counting device, and when the encoder is not moved or power is cut off, the position is memorized by means of internal memory of the counting device. Thus, the encoder cannot move any further after a power failure, and when the encoder is in operation, the encoder cannot disturb the pulse output to lose the pulse, otherwise the zero point memorized by the counting device will shift, and the amount of the shift is unknown, and can only be known after the error result appears. On one hand, when the elevator 150 is stopped suddenly by accident, the wire rope on the motor and the motor can slip, and the motor rotary encoder loses pulses; on the other hand, when the elevator 150 is stopped urgently due to an unexpected power failure, the maintenance personnel may release the motor brake to move the elevator car 152, and the motor rotary encoder loses pulses due to the power failure. The problem of lost pulses of the motor rotary encoder causes the actual position to be inconsistent with the recorded position of the elevator controller, i.e. a floor-staggering phenomenon. In order to determine the relative height of the elevator car 152 in the hoistway 151 and the corresponding number of floors, it is necessary to acquire measured initial floor height data. The initial floor height data may be the relative height information in the hoistway 151 at each landing position of the elevator car 152, the number of rotary encoder pulses corresponding to the motor rotary encoder in the corresponding motor, or the relative height information converted from the number of rotary encoder pulses of the motor by a conversion formula.
And step 120, the triggering signal transmitting and receiving device acquires the current relative height information of the elevator car.
The signal emitting and receiving device 156 may adopt a common distance measuring technology such as infrared, ultrasonic, laser, etc., and at least includes a set of signal emitting and receiving units, and the signal reflecting device 157 may be a corresponding baffle plate for reflecting signals, and the baffle plate may be a plane or an arc surface. In addition, the signal transmitting and receiving device 156 and the signal reflecting device 157 may be interchangeable and may be mounted above or below relative to the elevator car 152. In the embodiment, the signal transmitting and receiving device 156 is installed at the bottom of the elevator car 152, the signal reflecting device 157 is installed at the bottom of the hoistway 151, and the signal transmitting and receiving device 156 and the signal reflecting device 157 correspond to each other one by one along the direction of the elevator car running track.
Specifically, when the elevator 150 is powered off unexpectedly and the floor fault occurs due to an unexpected emergency stop, after power supply is restored, the signal transmitting and receiving device 156 is triggered to transmit a signal, the signal is reflected by the signal reflecting device 157 and then received by the signal transmitting and receiving device 156, and the relative height information of the elevator car 152 in the hoistway 151 can be obtained through calculation according to the signal transmitting and receiving time.
And step 130, determining a correction direction with the optimal correction time according to the comparison result of the current relative height information and the initial layer height data.
Wherein, the optimal correction time refers to the corresponding correction shortest path under the same correction speed rule.
Specifically, the current relative height information and the initial layer height data are converted into data information of the same metering unit for comparison, for example, the pulse number of a motor rotary encoder in the initial layer height data is converted into the relative height information through a conversion formula.
Illustratively, the initial layer height data Nth layer corresponds to a relative height HNIf the current relative height information is in HN-1And HNIn between, it may be determined that the current elevator car 152 is not in a flat-bed state, and further the current relative height information may be compared to HN-1And HNAnd respectively carrying out difference calculation, and comparing and determining the floor with the minimum height difference value as the elevator correction direction. For example, if the calculation result determines that N-1 is the floor with the minimum altitude difference, the correction direction with the optimal correction time is determined downwards, otherwise, the correction direction with the optimal correction time is determined upwards.
And step 140, controlling the elevator car to run according to the correction direction until the leveling sensor reaches the nearest magnetism isolating plate, and recording the current floor data.
Wherein the floor data may, but does not only, include the number of floors the elevator car 152 was corrected to.
Illustratively, as shown in fig. 2, the current relative height information of the elevator car 152 is located in the initial floor height data H1And H2And the calculation result determines that the 2 nd floor is the floor with the minimum height difference value, and then the floor is determined to be corrected upwardsWhen a leveling sensor 155 on the elevator car 152 moves upwards along with the elevator car 152 and senses that the 2 nd floor corresponds to the magnetism isolating plate 154, the elevator car 152 is determined to be in a leveling state, the elevator car 152 is controlled to stop running, and the floor number of the elevator car 152 in the floor data is changed into the 2 nd floor. If the elevator 150 further includes a motor with a motor rotary encoder, it is also necessary to change the number of rotary encoding pulses in the motor rotary encoder to the number of rotary encoding pulses corresponding to layer 2 in the initial layer height data.
According to the technical scheme, the optimal correction direction of the correction time is determined by comparing the elevator car relative height information measured in real time with the initial floor height data, and then the elevator car with staggered floors is corrected, so that the problems that the elevator car is staggered floors and data are wrong due to the fact that a steel wire rope slips when the elevator suddenly stops or the car moves after the system is powered off are solved, the actual stopping position of the elevator car is corrected quickly, the safety of the elevator is improved, and the technical effect of the staggered floor correction efficiency is improved.
Example two
Fig. 3 is a flowchart of an elevator floor fault correction method according to a second embodiment of the present invention, which is further refined based on the technical solution of the first embodiment, and optionally, the elevator floor fault correction method includes the following steps:
and step 210, controlling the elevator car to move upwards at a low speed from the bottommost flat floor position, and recording the pulse number of the current motor rotary encoder when the flat floor sensor reaches one magnetism isolating plate.
As shown in fig. 2, the bottommost level position is the level position of layer 1, the accuracy of the level sensor in sensing the magnetic shield is ensured at a low speed, the level sensor can also run at a variable speed under the condition of ensuring the accuracy, and a motor rotary encoder is arranged in the motor. The motor rotary encoder outputs pulses when rotated, and the position thereof is known by a counting device.
And 220, converting the pulse number of the motor rotary encoder into relative height information through a conversion formula, and recording the relative height information in an elevator controller as initial floor height data of the elevator car at the moment.
The conversion formula can be obtained by an elevator motor and a related mechanical structure thereof, and the pulse number of the motor rotary encoder can be converted into relative height information through the conversion formula and recorded in an elevator controller.
Illustratively, the elevator car 152 is controlled to move upwards at a low speed from the 1 st floor leveling position, the initial pulse number of the motor rotary encoder is 0, and when the floor leveling sensor senses the Nth magnetism isolating plate, the current pulse number of the motor rotary encoder is recorded and is recorded as PN. Number of pulses P of motor rotary encoderNConverting into relative height information through a conversion formula, and recording as HNAnd recorded in the elevator controller as the initial floor height data of the elevator car at that time. The initial layer height data is recorded as follows:
| floor level | Relative altitude information | Pulse number of |
| 1 layer of | H1 | 0 |
| 2 layers of | H2 | P2 |
| …… | …… | …… |
| N-1 layer | HN-1 | PN-1 |
| N layer | HN | PN |
And step 230, acquiring the measured initial floor height data when the elevator car is in an unexpected emergency stop in the running state.
And step 240, the triggering signal transmitting and receiving device acquires the current relative height information of the elevator car.
And step 250, determining the correction direction with the optimal correction time according to the comparison result of the current relative height information and the initial layer height data.
Because certain measurement errors exist in the current relative height information during the measurement process, the measurement error range needs to be considered during the comparison process with the initial layer height data. Assuming that the measurement error is Δ H and the measurement accuracy is generally less than half of the minimum layer height, the relative height range corresponding to the Nth layer is HN±△H。
Optionally, if the current relative altitude information is in the initial layer altitude data range [ H ]N-1+△H]And [ H ]N-△H]Determining that the current position of the elevator car is in a layer N-1;
judging whether the nearest floor is N floors or N-1 floors, and taking the nearest floor as a correction direction;
wherein HNInitial layer height data of the Nth layer, and delta H is a measurement error.
Illustratively, when Δ H is half the minimum floor height, as shown in fig. 2, the elevator car 152 current relative height information is in the initial floor height data range [ H [ ]1+△H]And [ H ]2-△H]In between, it can be determined that the current position of the bottom of the elevator car is in floor 1, and further the current relative height information of the elevator car 152 and H are calculated separately1And H2The distance of (a) to (b),and if the comparison determines that the nearest floor is the 2 nd floor, the 2 nd floor is taken as the correction direction.
Optionally, if the current relative height information is in the initial layer height data range HNThe direction is downward or upward as a correction direction when the elevator car is not in a flat layer state;
wherein HNInitial layer height data of the Nth layer, and delta H is a measurement error.
Illustratively, since the current relative altitude information when measured is in the initial layer altitude data range HNWhen the Δ H is not in a flat-bed state and the elevator car is not in a flat-bed state, it cannot be determined whether the current floor of the elevator car 152 is the nth floor or the N-1 th floor. In case the exact floor is not determined, a preset direction may be taken as a correction direction, which may be downwards or upwards, or randomly upwards or downwards.
Optionally, if the current relative height information is in the initial layer height data range HNAnd +/-Delta H, the elevator car is in a flat-layer state, and the elevator can directly correct and record the data of the current floor without running.
Optionally, the correction direction may also be selected based on the height of the floor on which the elevator car 152 is currently located. If the current elevator car 152 is at a high floor and near the top floor, to avoid elevator rushing to the top, the correction direction may be preferentially set to down, if the current elevator car 152 is at a low floor and near the bottom floor, to avoid elevator squat, the correction direction may be preferentially set to up.
And step 260, controlling the elevator car to run according to the correction direction until the leveling sensor reaches the nearest magnetism isolating plate, and recording the current floor data.
Alternatively, the correction direction may also be a preset floor. And controlling the elevator car to run according to the correction direction until the leveling sensor reaches the magnetic isolation plate of the preset floor, and recording the data of the current floor.
Optionally, if the current relative height information is in the initial layer height data range HNWhen the elevator car is in a flat-layer state and the correction direction is a preset floor, the elevator can be corrected to the preset floorAnd recording the data of the current floor.
The technical scheme of this embodiment, through survey and record initial floor height data for compare with current relative altitude information in order to confirm the optimal direction of correction time, and then rectify the elevator car on wrong floor, solved because of the elevator appear the wire rope when scramming or the system outage back car takes place to remove and cause the problem of elevator car wrong floor and data mistake, realize the actual stop position of quick correction elevator car, improve the security of elevator, and improve the technological effect of wrong floor correction efficiency.
On the basis of the above technical solution, the steps 210-220 may be replaced by:
and controlling the elevator to move upwards at a low speed from the lowest-layer leveling position, and when the leveling sensor reaches a magnetic isolation plate, transmitting a signal through a signal transmitting and receiving device to obtain the relative height information of the elevator car at the moment as initial-layer height data and record the initial-layer height data in an elevator controller.
Illustratively, the elevator car 152 is controlled to move upwards at a low speed from the leveling position of the 1 st floor, when the leveling sensor reaches the nth magnetism isolating plate, the elevator car 152 is suspended, and the signal transmitting and receiving device is triggered to transmit a signal to acquire the current relative height information of the elevator car 152, which is recorded as HN. The initial layer height data is recorded as follows:
| floor level | |
| 1 layer of | |
| 2 layers of | H2 |
| …… | …… |
| N-1 layer | HN-1 |
| N layer | HN |
The step 210 and the step 220 are replaced by the step of utilizing the signal transmitting and receiving device to measure the initial floor height data, so that the use of a motor rotary encoder can be avoided, the problem of data error caused by the technical defects of an elevator rotary encoder is solved, the actual stopping position of an elevator car is quickly corrected, the safety of an elevator is improved, and the technical effect of the efficiency of the staggered floor correction is improved.
