Description

Technical Field

[0001] This invention relates to the technical field of elevators, and more particularly to a positioning control method, device, equipment, and storage medium. Background Technology

[0002] High-rise buildings are often equipped with one or more elevators for users to go up and down floors, move goods, etc.

[0003] To ensure the safe operation of elevators, forced deceleration switches and limit switches are installed sequentially along the elevator's direction of travel in the shaft, near the upper and lower terminals, to control the car. The forced deceleration switches control car deceleration and detect overspeed at the terminals, while the limit switches prevent the car from overshooting or bottoming out.

[0004] Currently, most forced deceleration switches and limit switches use separate hardware switches, such as mechanical switches and magnetic switches. These separate hardware switches rely on a variety of cables and other accessories, making their configuration complex and costly. Summary of the Invention

[0005] This invention provides a positioning control method, device, equipment, and storage medium to address the problem of reducing the configuration complexity and cost of car control.

[0007] When the car moves in the hoistway, the light sensor is activated to transmit and receive the first light signal and the second light signal respectively.

[0008] When the photosensor overlaps with the magnetic shielding plate, the first change information of the first light signal and the second change information of the second light signal in terms of whether or not it is blocked are recorded respectively.

[0009] The current floor of the elevator car is identified based on the first change information and the second change information;

[0010] Based on the second change information, the car performs control operations adapted to the current floor.

[0011] According to another aspect of the present invention, a positioning control device is provided, wherein a light sensor is provided on an elevator car, and a plurality of magnetic plates for marking floors are provided in the building shaft, the device comprising:

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0032] Example 1

[0033] Figure 1 This is a flowchart of a positioning control method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where an elevator car is controlled using a light sensor and a magnetic shield. The method can be executed by a positioning control device, which can be implemented in hardware and / or software and can be configured in an electronic device. For example... Figure 1 As shown, the method includes:

[0034] Step 101: When the car moves in the hoistway, the light sensor is activated to transmit and receive the first light signal and the second light signal respectively.

[0035] Different types of buildings, especially high-rise buildings, have different transportation needs for people and goods. Therefore, different types of elevators can be deployed in buildings according to different transportation needs, such as passenger elevators, freight elevators, sightseeing elevators, etc. This embodiment does not impose any restrictions on this.

[0036] The structure of elevators also varies among different types of elevators.

[0037] In one example, the components of a certain type of elevator include a traction machine, control cabinet, speed governor, door operator, car frame, car door, counterweight guide rail, car guide rail, guide rail support, traveling cable, counterweight device, compensating chain (cable), landing door, guide device for compensating chain (cable), buffer, etc.

[0038] In some types of elevators, the traction machine, control cabinet, speed governor, traveling cable, etc., can be omitted.

[0039] These components can be divided into different sets according to their functions, thus forming various subsystems that support the operation of the elevator. The elevator controller is connected to multiple systems of the elevator via wired means such as serial port or serial clock line (SCL). The controller monitors each system and controls the operation of each subsystem.

[0040] In one example, the system includes a door system, a frequency conversion system, a call system, and a traction system. The door system is used to control the elevator doors, which include the car door and the doors of the waiting halls on each floor. The frequency conversion system is used to control the frequency converter. The call system is used to control the logic of internal call (calling the elevator from inside the car) and external call (calling the elevator from the waiting hall). The traction system is used to control the car's movement in the hoistway.

[0041] In this embodiment, a light sensor is installed on the elevator car. When the elevator is running and the car moves in the shaft, the light sensor can be activated. The light sensor itself transmits and receives a first light signal and a second light signal respectively.

[0042] For example, both the first optical signal and the second optical signal are infrared optical signals.

[0043] The first optical signal and the second optical signal may have some of the same functions and some of the different functions. The first optical signal can be used to level the car, and the second optical signal can be used to limit the movement of the car.

[0044] The so-called self-transmission and reception of the first and second optical signals can refer to the photosensitive sensor emitting and receiving the first and second optical signals.

[0045] Furthermore, such as Figure 2 As shown, the light sensor 200 is provided with two arm structures 210, a first light emitter 221, a first light receiver 222, a second light emitter 231, and a second light receiver 232.

[0046] The first light transmitter 221 is installed in one of the arm structures 210 and the first light receiver 222 is installed in the other arm structure 210. The positions of the first light transmitter 221 and the first light receiver 222 are opposite to each other. The first light transmitter 221 emits a first light signal and the first light receiver 222 receives the first light signal.

[0047] The second light transmitter 231 is installed in one of the arm structures 210 and the second light receiver 232 is installed in the other arm structure 210. The positions of the second light transmitter 231 and the second light receiver 232 are opposite to each other. The second light transmitter 231 emits a second light signal and the second light receiver 232 receives the second light signal.

[0048] The first optical transmitter and the second optical transmitter can be installed in one of the arm structures, and the first optical receiver and the second optical receiver can be installed in the other arm structure; or, the first optical transmitter and the second optical receiver can be installed in one of the arm structures, and the first optical receiver and the second optical transmitter can be installed in the other arm structure.

[0049] Step 102: When the photosensor and the magnetic shield overlap, record the first change information of the first light signal in terms of whether or not it is blocked, and the second change information of the second light signal in terms of whether or not it is blocked.

[0050] In this embodiment, multiple magnetic shielding plates for marking floors are installed in the building shaft, and the magnetic shielding plates have one or more holes.

[0051] The marked floors can include terminal stations and secondary terminal stations. Terminal stations include the top floor and the bottom floor of a building. Secondary terminal stations are floors close to the terminal stations, and the distance between them (in terms of floor number) is less than or equal to a preset threshold. Secondary terminal stations include the second-to-top floor and the second-to-bottom floor of a building. The second-to-top floor is a floor close to the top floor, and the distance between it and the top floor (in terms of floor number) is less than or equal to a preset threshold. The second-to-bottom floor is a floor close to the bottom floor, and the distance between it and the bottom floor (in terms of floor number) is less than or equal to a preset threshold.

[0052] Generally, the structures of each magnetic shielding plate are not the same, so that different magnetic shielding plates with different structures can be used to mark different floors.

[0053] In one example, such as Figure 3A As shown, the top of the magnetic shielding plate marked with a mark contains a hole, as... Figure 3B As shown, the bottom of the marked magnetic shielding plate contains a hole, as... Figure 3C As shown, the magnetic shielding plate of the second-layer layer has two vertically distributed holes, as... Figure 3D As shown, the bottom of the magnetic shielding plate of the second layer has three holes vertically distributed.

[0054] Of course, the above-described structure of the magnetic shielding plate is merely an example. In implementing this embodiment, other magnetic shielding plate structures can be configured according to actual circumstances, and this embodiment does not impose any limitations on this. Furthermore, in addition to the above-described magnetic shielding plate structure, those skilled in the art can also employ other magnetic shielding plate structures according to actual needs, and this embodiment does not impose any limitations on this either.

[0055] In a horizontal projection, the magnetic shielding plate is located on the optical path of the photosensor transmitting and receiving the first optical signal and the optical path of the second optical signal. For example, in a horizontal projection, the magnetic shielding plate is located between the two arm structures of the photosensor. Furthermore, the holes in the magnetic shielding plate are located on the optical path of the first optical signal and / or the optical path of the second optical signal.

[0056] Therefore, when the car moves in the hoistway, when the photosensitive sensor and the magnetic shielding plate do not overlap, the first and second light signals are not blocked by the magnetic shielding plate. When the photosensitive sensor and the magnetic shielding plate overlap, the first and / or second light signals may be blocked by the magnetic shielding plate, or they may pass through the hole in the magnetic shielding plate and thus not be blocked.

[0057] If the first light signal and the second light signal are blocked at the same time, it can be confirmed that the photosensor and the magnetic shielding plate overlap. At this time, the first change information of the first light signal in terms of whether it is blocked and the second change information of the second light signal in terms of whether it is blocked can be recorded respectively.

[0058] For unobstructed areas, an OFF signal can be used; for obstructed areas, an ON signal can be used.

[0059] Furthermore, in order to eliminate interference from falling objects, noise, etc., when the duration of simultaneous blocking of the first light signal and the second light signal exceeds a threshold, it is confirmed that the photosensor and the magnetic shielding plate overlap.

[0060] Step 103: Identify the current floor of the elevator car based on the first change information and the second change information.

[0061] Generally, the holes in the magnetic shielding plates used to mark different floors are not the same in terms of location and number. Therefore, the combination of the first change information of the first light signal and the second change information of the second light signal in terms of whether or not it is blocked is also different. Therefore, the magnetic shielding plate can be identified based on the combination of the first change information of the first light signal and the second change information of the second light signal in terms of whether or not it is blocked, thereby identifying the floor where the car is currently located.

[0062] In the specific implementation, the system queries the first identification condition set by the peer station and the second identification condition set by the secondary station. The first identification condition is used to identify the peer station, and the second identification condition is used to identify the secondary station. The first identification condition and the second identification condition are not the same.

[0063] like Figures 3A to 3D As shown, when the holes in the magnetic shielding plate are not aligned with the first light signal and the holes in the magnetic shielding plate are aligned with the second light signal, if the first change information includes the change from unblocked to blocked, it indicates that the photosensor overlaps with the magnetic shielding plate. Then, the distance the car moves can be measured based on parameters such as the speed and time of the car's movement.

[0064] During the process of reaching the preset first threshold (such as the middle position of the magnetic shield), the second change information is compared with the first identification condition and the second identification condition respectively.

[0065] If the second change information meets the first identification condition, then the current floor of the elevator car is determined to be the terminal station.

[0066] For example, such as Figure 3A , Figure 3B As shown, if the second change information sequentially includes changes from unobstructed to obstructed, i.e., OFF-ON, then it can be determined that the current floor of the car is the terminal station.

[0067] If the second change information meets the second identification condition, then the current floor of the elevator car is determined to be the secondary terminal station.

[0068] For example, such as Figure 3C , Figure 3D As shown, if the second change information sequentially includes changes of unobstructed, obstructed and unobstructed, i.e., OFF-ON-OFF, then it can be determined that the current floor of the car is the secondary terminal station.

[0069] Of course, the first and second identification conditions described above are merely examples. In implementing this embodiment, other first and second identification conditions can be set according to the actual structure of the magnetic shielding plates configured at the terminal station and the secondary terminal station. This embodiment does not impose any limitations on this. In addition, besides the first and second identification conditions described above, those skilled in the art can also adopt other first and second identification conditions as needed. This embodiment does not impose any limitations on this either.

[0070] Step 104: Based on the second change information, perform control operations on the car to adapt to the current floor.

[0071] In practice, the second optical signal can be used to limit the car's movement. The application of the second optical signal varies under different circumstances. For example, the application of the second optical signal is different under normal operation and maintenance conditions, and it is also different at the terminal station and the secondary terminal station. Therefore, under different circumstances, the car can be controlled according to the second change information of the second optical signal to perform control operations adapted to the current floor.

[0072] In one embodiment of the present invention, step 104 may include the following steps:

[0073] Step 401: If the current floor is the terminal station, query the distance the car has moved.

[0074] Step 402: When the distance reaches the preset first threshold, perform a leveling operation on the car.

[0075] If the car is currently at a terminal station and cannot continue moving upwards (to the top floor) or downwards (to the bottom floor), then the terminal station is the floor to be stopped at. In this case, you can query the previously calculated distance the car has moved.

[0076] like Figure 4A As shown, when the distance reaches the preset first threshold (such as the middle position of the magnetic shield), both the first light signal (labeled "1") and the second light signal (labeled "2") are blocked. At this time, the car can be leveled, that is, when the car approaches the stopping station, the action of making the car sill and the landing door sill reach the same plane.

[0077] Under normal circumstances, leveling operations should meet the following verification criteria:

[0078] 1. For AC dual-speed elevators with a rated speed of less than or equal to 0.63 m / s, the range should be within ±15 mm.

[0079] 2. For AC dual-speed elevators with a rated speed greater than or equal to 0.63 m / s and less than or equal to 1.0 m / s, the range should be within ±30 mm.

[0080] 3. For elevators with other speed control methods, the range should be ±15mm.

[0081] Step 403: Query the limit conditions set by the peer station.

[0082] Step 404: If the second change information satisfies the limit condition, then generate the first limit signal.

[0083] Step 405: Control the car to stop moving in the hoistway according to the first limit signal.

[0084] In this embodiment, a limit condition can be set in advance for the terminal station, which indicates the position where the car is restricted from moving under normal conditions.

[0085] The second change information of the second optical signal is compared with the limiting condition. If the second change information meets the limiting condition, the first limiting signal can be generated.

[0086] For example, such as Figure 4B , Figure 4C (Upward) and Figure 4D As shown in (downward), the car is limited to moving a distance of L2. If the second change information sequentially includes changes of unobstructed, obstructed and unobstructed, i.e., OFF-ON-OFF, it means that the second light signal reaches the hole of the magnetic shielding plate and the car moves a distance of L2, then the first limit signal can be generated.

[0087] The first limit signal is sent to the elevator control system, which responds to the first limit signal and stops the car from moving in the hoistway.

[0088] In another embodiment of the present invention, step 104 may further include the following steps:

[0089] Step 406: If a first maintenance command triggered for the car is received, cancel the first limit signal and control the car to continue moving in the hoistway.

[0090] When the elevator is under maintenance, short-circuiting the first limit signal is permitted (invalid).

[0091] When the first limit signal is active, the commissioning personnel can trigger the first maintenance command through the commissioning tool or the keyboard of the control panel. At this time, the first limit signal is invalid. The first limit signal is canceled, and the elevator enters the limit short-circuit mode. The car can continue to perform maintenance up (at the top floor) or down (at the bottom floor) a certain distance.

[0092] Step 407: Query the limit conditions set by the peer station.

[0093] Step 408: If the second change information satisfies the limit condition, then generate the second limit signal.

[0094] Step 409: Control the car to stop moving in the hoistway according to the second limit signal.

[0095] In this embodiment, limit conditions can be set in advance for the terminal station, which represent the position where the car is restricted from moving during maintenance.

[0096] The second change information of the second optical signal is compared with the limit condition. If the second change information satisfies the limit condition, a second limit signal can be generated.

[0097] For example, such as Figure 4B As shown, the maximum distance the car can move is L1. If the second change information sequentially includes the changes of unobstructed, obstructed, unobstructed and obstructed, that is, OFF-ON-OFF-ON, it means that the second light signal leaves the hole of the magnetic shielding plate and the distance the car moves reaches L1, then the second limit signal can be generated.

[0098] The second limit signal is sent to the elevator control system. The elevator control system responds to the second limit signal, and the elevator enters the software limit state, controlling the car to stop moving in the hoistway. At this time, the car can no longer continue to perform upward (at the top floor) or downward (at the bottom floor) maintenance.

[0099] In another embodiment of the present invention, step 104 may further include the following steps:

[0100] Step 410: If a second maintenance command triggered for the car is received, cancel the second limit signal and control the car to continue moving in the hoistway.

[0101] Step 411: If the car moves to the preset position, activate the limit switch to stop the car from moving in the hoistway.

[0102] When the elevator is in the limit short-circuit state, short-circuiting the second limit signal is allowed (invalid).

[0103] When the second limit signal is active, if the commissioning personnel want to continue the inspection by going up (to the top floor) or down (to the bottom floor), they can trigger the second inspection command through the commissioning tool or the keyboard of the control panel. At this time, the second limit signal is invalid. When the second limit signal is canceled, the elevator enters the extreme short-circuit state, and the car can continue to go up (to the top floor) or down (to the bottom floor) for a certain distance.

[0104] At this point, continuing to ascend (on the top floor) or descend (on the bottom floor) for maintenance will trigger the hardware limit switch, thereby disconnecting the safety circuit and causing the elevator to stop. Therefore, when entering the limit short-circuit state, a prompt operation can be performed to indicate the risk of the limit switch, for example, by playing a prompt audio message such as "The elevator is about to touch the limit switch, please be careful."

[0105] In another embodiment of the present invention, step 104 may further include the following steps:

[0106] Step 412: If the current floor is a secondary terminal station, the positional relationship between the photosensitive sensor and the magnetic shielding plate is identified based on the first change signal.

[0107] If the current floor of the car is a secondary terminal station, it can continue to go up (to the top floor) or down (to the bottom floor). When the secondary terminal station is not the floor where the car stops, the positional relationship between the photosensitive sensor and the magnetic shield can be identified based on the first change signal of the first light signal.

[0108] For example, such as Figures 3A-3D As shown, if the first change information sequentially includes changes of unobstructed, obstructed and unobstructed, i.e., OFF-ON-OFF, then it can be determined that the positional relationship between the photosensor and the magnetic shield is separated.

[0109] Step 413: If the positional relationship is that the photosensor and the magnetic shield are separated, then query the multiple positioning conditions set for the secondary terminal station.

[0110] Step 414: If the second change signal satisfies the positioning condition, then determine the secondary terminal station as the first floor number corresponding to the positioning condition.

[0111] When the photosensitive sensor and the magnetic shield are separated in the positional relationship, multiple positioning conditions set for the secondary terminal station can be queried. These positioning conditions are the conditions for locating the secondary terminal station. Therefore, each positioning condition is configured with the first floor number.

[0112] In different naming methods, the first floor number may carry non-numeric information such as letters or Chinese characters, for example, basement 1, rich 2, 13A, etc. Therefore, for such non-numeric first floor numbers, the first floor number can be mapped to a number.

[0113] The second change signal of the second optical signal is compared with each positioning condition.

[0114] If the second change signal satisfies a certain positioning condition, then the secondary terminal station can be determined to be the first floor number corresponding to that positioning condition.

[0115] For example, such as Figure 3C As shown, if the second change information sequentially includes changes of unobstructed, obstructed, unobstructed, obstructed, unobstructed, obstructed and unobstructed, i.e., OFF-ON-OFF-ON-OFF-ON-OFF, then the secondary terminal station is determined to be the first floor number representing the secondary top floor.

[0116] like Figure 3D As shown, if the second change information sequentially includes changes of unobstructed, obstructed, unobstructed, obstructed, unobstructed, obstructed, unobstructed, obstructed and unobstructed, i.e., OFF-ON-OFF-ON-OFF-ON-OFF-ON-OFF, then the secondary terminal station is determined to be the first floor number representing the secondary bottom layer.

[0117] Step 415: Query the elevator record for the second floor the car has reached.

[0118] Step 416: If the first floor number is different from the second floor number, notify the elevator to correct the second floor number to the first floor number and control the car to perform a deceleration operation.

[0119] Step 417: If the first floor number is the same as the second floor number, control the car to perform a deceleration operation.

[0120] In this embodiment, the elevator control system can be queried for the elevator's recorded number of the second floor that the car has currently reached, and the number of the first floor can be compared with the number of the second floor.

[0121] If the first floor number is different from the second floor number, the elevator will be notified to correct the second floor number to the first floor number, and the car will be controlled to perform a deceleration operation.

[0122] If the first floor number is different from the second floor number, it can be confirmed that a floor misalignment has occurred. In this case, the elevator control system is notified to correct the second floor number to the first floor number, based on the first floor number, and the car is controlled to perform a deceleration operation to open the door with the optimal curve leveling, so as to avoid the elevator from stopping suddenly due to the floor misalignment.

[0123] If the first floor number is different from the second floor number, the elevator car can be controlled to decelerate and open the door at the optimal level, thus avoiding sudden stops caused by misalignment.

[0124] In this embodiment, a photosensor is installed on the elevator car, and multiple magnetic plates for marking floors are installed in the building shaft. When the car moves in the shaft, the photosensor is activated, transmitting and receiving a first light signal and a second light signal respectively. When the photosensor overlaps with the magnetic plates, it records the first change information of the first light signal in terms of whether it is blocked and the second change information of the second light signal in terms of whether it is blocked. Based on the first and second change information, the current floor of the car is identified. Based on the second change information, the car performs control operations adapted to the current floor. This embodiment uses the changes in the obstruction of two beams of light to identify the floor in order to perform corresponding control operations. This can improve the richness of information, improve the accuracy of floor identification, thereby improving the accuracy of control operations and ensuring the safe operation of the elevator. The magnetic plates are mechanical structures, reducing the reliance on multiple cables and other accessories, greatly improving the simplicity of configuration and reducing costs.

[0125] Example 2

[0126] Figure 5 This is a schematic diagram of a positioning control device provided in Embodiment 2 of the present invention. Figure 5 As shown, a light sensor is installed on the elevator car, and multiple magnetic plates for marking floors are installed in the building shaft. The device includes:

[0127] The photosensitive sensor activation module 501 is used to activate the photosensitive sensor and transmit and receive a first light signal and a second light signal respectively when the car moves in the hoistway.
