Example 1
Referring to fig. 1, fig. 1 is a schematic structural diagram of a first apparatus for leveling calibration of an elevator according to an embodiment of the present application, as shown in the drawing, an apparatus 100 for leveling calibration of an elevator according to an embodiment of the present application includes:
a driving climbing gear 110 for driving the cage 101 of the lifter to move;
a driven gear 120 for following the movement of the driving climbing gear 110;
a primary encoder 130 coupled to the active climbing gear 110 via a first operating shaft 111 for recording a first calibration reading and a first position reading of the elevator;
a secondary encoder 140 coupled to the driven gear 120 via a second operating shaft 121 for recording a second calibration reading and a second position reading of the elevator;
a controller 150 for obtaining a first calibration reading and a first position reading recorded by the primary encoder 130, and a second calibration reading and a second position reading recorded by the secondary encoder 140;
comparing the first calibration reading with the first position reading to obtain a first deviation;
comparing the second calibration reading with the second position reading to obtain a second deviation;
and determining that the elevator is at the target floor under the condition that the first deviation is smaller than or equal to a first preset threshold value and the second deviation is smaller than or equal to a second preset threshold value.
Specifically, the driving climbing gear 110 and the driven gear 120 are mounted on the cage 101 of the elevator, the primary encoder 130 is connected to the driving climbing gear 110 through the first operating shaft 111, and the secondary encoder 140 is connected to the driven gear 120 through the second operating shaft 121. When the elevator moves, power is applied to the driving climbing gear 110 to drive the cage 101 of the elevator to move up and down on the climbing rack 102, and the driven gear 120 does not participate in the power and only follows the driving climbing gear 110 to move on the climbing rack 102, so that interference caused by external power application of the auxiliary encoder 140 connected with the driven gear 120 can be reduced, and compared with the main encoder 130 connected with the driving climbing gear 110, the auxiliary encoder 140 is not easy to damage and can be used for a long time.
Before the elevator is leveled, the building floor height in the construction area is first calibrated, that is, the destination floor to which the elevator is to travel is determined, the controller 150 records the number of destination floors, and the main encoder 130 and the sub encoder 140 simultaneously record the calibration readings of the destination floor height, and it is understood that the calibration readings of the destination floor height of the main encoder 130 and the sub encoder 140 are also offset due to a certain deviation of the installation positions of the main encoder 130 and the sub encoder 140. That is, the primary encoder 130 records a first calibration reading, the secondary encoder 140 records a second calibration reading, the primary encoder 130 and the secondary encoder 140 communicate with the controller 150 through a CAN (Controller Area Network, control area network) bus protocol, and respectively send the first calibration reading and the second calibration reading to the controller 150, and the controller 150 correspondingly acquires the first calibration reading recorded by the primary encoder 130 and the second calibration reading recorded by the secondary encoder 140, and controls the cage 101 of the elevator to travel to the target floor according to the recorded number of target floors.
When the elevator cage 101 reaches the destination floor, the primary encoder 130 and the secondary encoder 140 record the position readings of the current elevator cage 101 at the same time, and it is understood that, because there is a certain deviation between the installation positions of the primary encoder 130 and the secondary encoder 140, there is a deviation between the position readings of the elevator cage 101 recorded by the primary encoder 130 and the secondary encoder 140, that is, the primary encoder 130 records the first position reading, the secondary encoder 140 records the second position reading, and the primary encoder 130 and the secondary encoder 140 respectively send the first position reading and the second position reading to the controller 150 through the CAN bus protocol. The controller 150 correspondingly obtains a first position reading recorded by the main encoder 130 and a second position reading recorded by the auxiliary encoder 140, compares the first calibration reading with the first position reading to obtain a first deviation, compares the second calibration reading with the second position reading to obtain a second deviation, compares the first deviation with a first preset threshold value, compares the second deviation with a second preset threshold value, and determines that the elevator is at the target floor under the condition that the first deviation is smaller than or equal to the first preset threshold value and the second deviation is smaller than or equal to the second preset threshold value. In this embodiment of the present application, the first preset threshold and the second preset threshold may be set and modified according to actual requirements, which is not limited in this embodiment of the present application.
In an alternative embodiment, the controller 150 is further configured to issue an alarm and terminate operation of the elevator if the first deviation is greater than a first preset threshold and/or the second deviation is greater than a second preset threshold.
Specifically, the controller 150 compares the first deviation with a first preset threshold value, compares the second deviation with a second preset threshold value, and indicates that the leveling calibration of the elevator has a larger deviation when the first deviation is greater than the first preset threshold value and/or the second deviation is greater than the second preset threshold value, and the controller 150 sends an alarm through a speaker to remind an operator that the leveling calibration has an abnormality, and terminates the operation of the elevator to ensure that the construction is safe.
In an alternative embodiment, both the primary encoder and the secondary encoder are absolute value encoders.
The absolute value encoder is a position sensor and is used for measuring the position of equipment, and unlike the traditional encoder, the absolute value encoder does not need a reference point and does not need memory, so that the accurate position of the equipment at present can be recorded at any time. When the elevator cage 101 stops moving or the primary and secondary encoders 130, 140 are restarted after being powered off, the primary and secondary encoders 130, 140 can quickly and accurately record the current absolute position of the elevator cage 101 without having to find a reference point.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a second apparatus for leveling an elevator according to an embodiment of the present application. In an alternative embodiment, as shown in fig. 2, the apparatus for elevator leveling calibration further comprises a peer sensor comprising:
a first sensing member 161 installed at each floor of the construction area;
a second sensing member 162 mounted to the bottom of the cage 101 of the elevator for transmitting an aligned signal to the controller in case the first sensing member 161 is detected;
the controller 150 is further configured to determine that the elevator is at the target floor when the first deviation is less than or equal to a first preset threshold value, the second deviation is less than or equal to a second preset threshold value, and the aligned signal sent by the second sensing component is received.
Specifically, the leveling sensor 160 includes a first sensing component 161 and a second sensing component 162, where there may be a plurality of first sensing components 161 respectively installed on the outer door rail 103 of each floor of the construction area, so as to perform leveling calibration on each floor; a second sensing element 162 is mounted to the bottom of the elevator cage 101 for cooperation with a first sensing element 161 mounted to the destination floor for leveling of the elevator. It will be appreciated that the first sensing element 161 and the second sensing element 162 can only achieve alignment sensing for mating if the distance difference is less than or equal to a preset distance difference threshold; in the case where the distance difference between the two is greater than the preset distance difference threshold, alignment sensing cannot be achieved. Before the elevator performs leveling, namely when a target floor to which the elevator is going is determined, correspondingly starting a first sensing component 161 installed on the target floor and a second sensing component 162 installed at the bottom of the elevator cage 101, when the elevator starts to move, the second sensing component 162 starts to search and detect the first sensing component 161, if the first sensing component 161 is successfully detected, the first sensing component 161 and the second sensing component 162 are successfully aligned, and the second sensing component 162 sends an aligned signal to the controller 150 through a CAN bus protocol; if the first sensing component 161 is not detected, this indicates that the first sensing component 161 is not successfully aligned with the second sensing component 162, and the second sensing component 162 does not send an aligned signal.
The controller 150 compares the first deviation with a first preset threshold value, and compares the second deviation with a second preset threshold value, and if the first deviation is less than or equal to the first preset threshold value and the second deviation is less than or equal to the second preset threshold value, that is, after the leveling calibration of the primary encoder 130 and the secondary encoder 140 is successful, the controller 150 determines whether an aligned signal sent by the second sensing part 162 is received, and if the aligned signal is received successfully, determines that the elevator reaches the target floor.
On the basis of performing leveling calibration on the main encoder 130 and the auxiliary encoder 140, the leveling calibration of the elevator can be further ensured to be smoothly and stably performed by performing alignment verification on the leveling sensor 160 again, so that the accuracy and redundancy of the leveling calibration are improved.
In an alternative embodiment, the controller 150 is further configured to issue an alarm and terminate operation of the elevator when the first deviation is less than or equal to a first preset threshold, the second deviation is less than or equal to a second preset threshold, and the aligned signal is not received.
The controller 150 compares the first deviation with a first preset threshold value, compares the second deviation with a second preset threshold value, and determines whether an aligned signal transmitted by the second sensing unit 162 is received or not when the first deviation is smaller than or equal to the first preset threshold value and the second deviation is smaller than or equal to the second preset threshold value, if the aligned signal is not received, the controller 150 sends an alarm through a speaker to remind an operator of the abnormality of the leveling calibration, and terminates the operation of the lifter to ensure the construction safety.
It should be noted that, when any one of the four elements of the primary encoder 130, the secondary encoder 140, and the first sensing component 161 and the second sensing component 162 of the peer sensor 160 fails, the controller 150 will send an alarm through the speaker to alert the operator that the component fails, so as to facilitate debugging and installation of the failed component.
In an alternative embodiment, both the first sensing component 161 and the second sensing component 162 are infrared sensors.
The infrared sensor is a sensor for processing data by utilizing infrared light, and is divided into an infrared receiver and an infrared emitter. In the embodiment of the present application, the first sensing part 161 is an infrared emitter, and emits infrared light of a specific wavelength outwards through an infrared emitting diode; the second sensing part 162 is an infrared receiver, and receives infrared light emitted from the first sensing part 161 through a photodiode.
Specifically, before the elevator performs leveling, when the destination floor to which the elevator is going is determined, the first sensing element 161 mounted on the destination floor and the second sensing element 162 mounted on the bottom of the elevator cage 101 are correspondingly turned on, when the elevator cage 101 starts to move, the first sensing element 161 mounted on the destination floor and the second sensing element 162 mounted on the bottom of the elevator cage 101 start to operate, the infrared emitting diode of the first sensing element 161 continuously emits infrared light outwards, the photodiode of the second sensing element 162 continuously receives the detected infrared light, and when the photodiode of the second sensing element 162 detects infrared light, the first sensing element 161 and the second sensing element 162 are successfully aligned, and the second sensing element 162 sends an aligned signal to the controller 150 through the CAN bus protocol.
It should be noted that, in the embodiment of the present application, the main encoder 130, the auxiliary encoder 140 and the opposite layer sensor 160 may all work independently and do not interfere with each other, and the auxiliary encoder 140 and the opposite layer sensor 160 may all be turned off separately. Specifically, when the secondary encoder 140 fails, it may be turned off and the calibration step of the first calibration reading and the first position reading skipped; when the first sensing component 161 and/or the second sensing component 162 of the layer sensor 160 fail, all the first sensing components 161 and the second sensing components 162 can be closed, and the calibration step of the layer sensor 160 is skipped, so that the debugging and the installation of the failed components are facilitated, other components which do not fail are not interfered, and the elevator can still work normally, and the redundancy requirement of the elevator flat layer calibration is met.
According to the device for leveling calibration of the lifter, the auxiliary encoder is arranged on the driven gear and does not participate in movement, so that the damage probability of the auxiliary encoder is reduced, the main encoder and the auxiliary encoder are utilized for mutual calibration, the accuracy and redundancy of leveling calibration of the lifter are improved, and the construction safety and stability are guaranteed.

It can be appreciated that the elevator provided in the embodiments of the present application includes the device for leveling calibration of an elevator provided in any one of the first embodiment, and the same technical effects can be achieved, so that repetition is avoided, and no further description is given here.
Example III
Referring to fig. 3, fig. 3 is a flow chart illustrating a method for calibrating an elevator leveling according to an embodiment of the present application, as shown in the fig. 3, the method for calibrating an elevator leveling according to the embodiment of the present application is applied to the apparatus for calibrating an elevator leveling according to any one of the first embodiment, and the method includes:

Before the elevator is leveled, the building floor height in the construction area is first calibrated, that is, the destination floor to which the elevator is to travel is determined, the controller 150 records the number of destination floors, and the main encoder 130 and the sub encoder 140 simultaneously record the calibration readings of the destination floor height, and it is understood that the calibration readings of the destination floor height of the main encoder 130 and the sub encoder 140 are also offset due to a certain deviation of the installation positions of the main encoder 130 and the sub encoder 140. That is, the primary encoder 130 records a first calibration reading, the secondary encoder 140 records a second calibration reading, the primary encoder 130 and the secondary encoder 140 communicate with the controller 150 through a CAN (Controller Area Network, control area network) bus protocol, and respectively send the first calibration reading and the second calibration reading to the controller 150, and the controller 150 correspondingly acquires the first calibration reading recorded by the primary encoder 130 and the second calibration reading recorded by the secondary encoder 140, and controls the cage 101 of the elevator to travel to the target floor according to the recorded number of target floors.
When the elevator cage 101 reaches the destination floor, the primary encoder 130 and the secondary encoder 140 record the position readings of the current elevator cage 101 at the same time, and it is understood that, because there is a certain deviation between the installation positions of the primary encoder 130 and the secondary encoder 140, there is a deviation between the position readings of the elevator cage 101 recorded by the primary encoder 130 and the secondary encoder 140, that is, the primary encoder 130 records the first position reading, the secondary encoder 140 records the second position reading, and the primary encoder 130 and the secondary encoder 140 respectively send the first position reading and the second position reading to the controller 150 through the CAN bus protocol. The controller 150 correspondingly obtains a first position reading recorded by the main encoder 130 and a second position reading recorded by the auxiliary encoder 140, compares the first calibration reading with the first position reading to obtain a first deviation, compares the second calibration reading with the second position reading to obtain a second deviation, compares the first deviation with a first preset threshold value, compares the second deviation with a second preset threshold value, and determines that the elevator is at the target floor under the condition that the first deviation is smaller than or equal to the first preset threshold value and the second deviation is smaller than or equal to the second preset threshold value. In this embodiment of the present application, the first preset threshold and the second preset threshold may be set and modified according to actual requirements, which is not limited in this embodiment of the present application.
In an alternative embodiment, the method further comprises:
in step 350, an alarm is raised and the operation of the elevator is terminated in the event that the first deviation is greater than a first preset threshold and/or the second deviation is greater than a second preset threshold.
Specifically, the controller 150 compares the first deviation with a first preset threshold value, compares the second deviation with a second preset threshold value, and indicates that the leveling calibration of the elevator has a larger deviation when the first deviation is greater than the first preset threshold value and/or the second deviation is greater than the second preset threshold value, and the controller 150 sends an alarm through a speaker to remind an operator that the leveling calibration has an abnormality, and terminates the operation of the elevator to ensure that the construction is safe.
