Description

Technical Field

[0001] This application relates to the field of elevator control technology, and in particular to an elevator leveling adjustment method, leveling adjustment device, and storage medium. Background Technology

[0002] With the development of elevator control technology, elevator control systems can calculate the elevator running curve based on the distance between floors. Elevator stopping methods include crawling stopping and direct stopping. Among them, due to slippage of elevator steel cables, the crawling stopping method is often used in practical applications.

[0003] The crawling and stopping process is as follows: the elevator starts and accelerates to a high speed, then decelerates to a crawling speed after reaching the deceleration point, entering the crawling phase. When the elevator's leveling switch encounters the leveling plate, the elevator stops according to the set deceleration curve. However, during the crawling and stopping process, due to installation issues, the center position of the leveling plate on each floor may deviate from the actual floor leveling position. In this case, leveling adjustment is required. Existing leveling adjustment methods involve adjusting the crawling speed or the deceleration curve to ensure stopping accuracy. However, this method only guarantees that the leveling plate is installed completely correctly. If the installation height of the leveling plate on a certain floor is not appropriate, there will be a deviation in the leveling accuracy of that floor. In this case, the only solution is to adjust the installation position of the leveling plate on that floor, which requires a significant amount of time and effort.

[0004] It is evident that existing leveling methods require considerable time and effort for leveling adjustments. Summary of the Invention

[0008] The creeping segment adjustment value for the multiple floors is determined based on the leveling distance and the preset creeping segment distance; the preset creeping segment distance is the creeping segment distance that the elevator travels when it stops at the leveling position after creeping.

[0009] During the process of the elevator crawling and stopping to the required floor of the multiple floors, when the elevator decelerates to enter the crawling section, the crawling section adjustment value of the required floor is obtained from the crawling section adjustment values ​​of the multiple floors based on the running direction of the elevator.

[0025] Furthermore, the delay time includes: the delay time of the leveling switch; determining the delay distance when entering the crawling section based on the delay time of entering the crawling section and the elevator speed when entering the crawling section includes:

[0026] Multiply the delay time of the leveling switch by the elevator speed when entering the crawling section to obtain the delay distance when entering the crawling section.

[0027] Furthermore, adjusting the leveling position of the floor to be stopped based on the target crawling distance of the floor to be stopped includes:

[0028] Obtain the initial leveling position of the elevator when entering the crawling section;

[0050] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0051] In the description of the embodiments of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0052] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0053] Existing elevator stopping procedures include: direct stopping and crawling stopping, such as... Figure 1As shown, the distance control for direct stopping is as follows: the elevator decelerates directly from high speed to zero during the deceleration phase. The distance control for crawling stopping is as follows: the elevator accelerates to high speed upon starting, reaches the deceleration point, and then decelerates to crawling speed, entering the crawling phase. When the elevator's leveling switch encounters the leveling plate, the elevator begins to stop according to the set deceleration curve. However, during crawling stopping, due to installation issues, the center position of the leveling plate on each floor may deviate from the actual floor leveling position. In this case, leveling adjustment is required. Existing leveling adjustment methods involve adjusting the crawling speed or the deceleration curve to ensure stopping accuracy. However, this method only guarantees that the leveling plate is installed correctly. If the leveling plate installation height on a certain floor is inappropriate, there will be a deviation in the leveling accuracy of that floor. In this case, the only solution is to adjust the installation position of the leveling plate on that floor, which requires considerable time and effort. Therefore, this application provides an elevator leveling adjustment method that allows for more convenient and faster leveling adjustments. Figure 2 As shown, this specifically includes steps 201 to 205:

[0054] 201. Obtain the leveling distance between the elevator and the leveling position after the elevator has crawled and stopped on multiple floors.

[0055] The elevator's leveling adjustment device can obtain the leveling distance between the elevator and the pre-recorded leveling position after the elevator has crawled and stopped at multiple floors. This leveling position is the pre-recorded leveling position for each floor, typically the center position of the leveling plate on each floor. This allows the system to control the elevator to determine the leveling distance between its stopping position and the corresponding pre-recorded leveling position after each floor's crawling and stopping. When the elevator stops at a preset floor, if it exceeds or fails to reach the preset floor's leveling position, the leveling distance between the elevator and the pre-recorded leveling position is not zero. If it reaches the preset floor's leveling position exactly, the leveling distance between the elevator and the pre-recorded leveling position is zero.

[0056] Specifically, during the elevator's ascent and descent, elevator commissioning or maintenance personnel can call the elevator on multiple floors one by one, recording the leveling status of each floor. When the elevator stops based on the call, if the elevator's stopping position is beyond the leveling position in the direction of travel, the leveling distance between the elevator and the leveling position is set to a negative distance; for example, if the elevator is 1.2 cm beyond the leveling position in the direction of travel, the corresponding leveling distance can be recorded as -1.2 cm. If the elevator's stopping position is not at the leveling position in the direction of travel, the leveling distance between the elevator and the leveling position is set to a positive distance; for example, if the elevator is 0.9 cm away from the leveling position in the direction of travel, the corresponding leveling distance can be recorded as +0.9 cm. If the elevator stops at the leveling position, that is, the elevator's stopping position matches the pre-recorded leveling position, the leveling distance is zero.

[0057] It's understandable that the leveling distance obtained when passing the same floor may differ depending on the elevator's direction of travel. For example, during an upward elevator ride, after the elevator stops, the stopping position may exceed the pre-recorded leveling position, while during a downward elevator ride, after the elevator stops, the stopping position may not reach the pre-recorded leveling position. When recording the leveling distance for multiple floors, the corresponding elevator direction of travel needs to be included.

[0058] 202. Determine the crawling segment adjustment value for multiple floors based on the leveling distance and the preset crawling segment distance.

[0059] After obtaining the leveling distances for multiple floors, the creep adjustment values ​​for multiple floors can be determined based on the leveling distances and the preset creep distances. It is understood that the elevator control system will automatically calculate the creeping and stopping operation curve based on the distance between two floors. However, when the elevator is actually running based on the operation curve, the elevator's stopping position may exceed or fall short of the recorded leveling position. In this case, the leveling distances for multiple floors can be input into the elevator control system, and the creep adjustment values ​​for multiple floors can be determined based on the leveling distances and the preset creep distances. The creep adjustment value is the leveling adjustment record value for the floor reached by the elevator going up or down. That is, the creep distance on the operation curve can be adjusted so that after the elevator creeps and stops, the elevator's stopping position exactly reaches the recorded leveling position of the floor.

[0060] The preset crawling distance is the crawling distance the elevator travels after crawling to a stop and then resting at the leveling position. In other words, it is the distance of the effective rising edge of the leveling signal from the leveling switch when the elevator stops at the normal leveling position. Figure 3As shown, the preset crawling distance is A. This means that during the elevator's deceleration from the high-speed section, when the rising edge signal of the leveling switch is triggered, the current speed becomes the crawling speed, and the elevator enters the crawling section. When the rising edge of the leveling switch ends, the elevator begins to decelerate from the crawling speed to a stop. If the elevator stops before reaching the leveling position (not yet leveled), the corresponding leveling distance can be set to +C, and the corresponding crawling adjustment value is A+C. If the elevator stops after reaching the leveling position (over-leveled), the corresponding leveling distance can be set to -B, and the corresponding crawling adjustment value is AB. By sequentially traversing all the floors the elevator travels in both the upward and downward directions, the crawling adjustment values ​​for all floors in the elevator's direction of travel can be obtained.

[0061] 203. When the elevator decelerates to enter the crawling section, the crawling section adjustment value of the floor to be stopped is obtained from the crawling section adjustment values ​​of multiple floors based on the elevator's running direction.

[0062] During the elevator's crawling and stopping process towards the multiple floors required to stop, when the elevator decelerates to enter the crawling phase, the crawling phase adjustment value for the required floor is obtained from the crawling phase adjustment values ​​of the multiple floors based on the elevator's running direction. Specifically, when the elevator decelerates, the elevator's leveling switch signal can be detected. When the leveling switch signal is detected and triggered, the elevator's current speed is used as the crawling speed, and it is determined that the elevator has entered the crawling phase. At this time, the current running direction of the elevator and the floor required to stop ahead can be determined. Based on the current running direction and the floor required to stop ahead, the corresponding crawling phase adjustment value is called to obtain the leveling distance D of the required floor. This leveling distance can be understood as a compensation distance, and the value of this leveling distance can be -B or +C. Understandably, the creep adjustment value for the floor to be stopped may differ for different operating directions. For example, if the elevator stops after creeping during the upward movement and the stopping position exceeds the pre-recorded leveling position, the creep adjustment value for the floor to be stopped will be AB. However, during the downward movement, if the elevator stops before the pre-recorded leveling position, the creep adjustment value for the floor to be stopped will be A+C.

[0063] Furthermore, to eliminate signal delays from the leveling switch or positional deviations caused by elevator cable slippage, the deceleration point on the elevator's running curve can be offset. Specifically, the running curve of the elevator as it crawls towards the floor to stop is obtained, and the deceleration point on the running curve is determined. The deceleration point is the position that triggers the elevator to begin decelerating towards the crawling section. Understandably, when the elevator starts normally, the elevator control system automatically calculates the running curve based on the current floor and the floor to stop ahead, including the deceleration point and the running speed. When deceleration is required at the floor to stop ahead, the system determines whether the distance to the deceleration point has been reached based on the current position information. When the deceleration point is reached, the elevator begins to decelerate according to the deceleration curve until it reaches the crawling speed. The deceleration point can be advanced or delayed based on a preset deceleration range; that is, for this deceleration point, a preset deceleration range F can be set via parameters, such as... Figure 4 As shown, the preset deceleration range F can be within ±30 cm of the deceleration point; the specific range is not limited here. Within this preset deceleration range F, delayed deceleration or advanced deceleration can be set to compensate for positional deviations.

[0064] 204. Based on the delay distance compensation when entering the crawling segment, the crawling segment adjustment value of the floor to be stopped is used to obtain the target crawling segment distance of the floor to be stopped.

[0065] During the deceleration process of the elevator, there will be a delay when entering the crawling section (i.e., entering the leveling section). At this time, the crawling section adjustment value of the floor to be stopped can be compensated based on the delay distance when entering the crawling section, so as to obtain the target crawling section distance of the floor to be stopped. This target crawling section distance is the actual deceleration delay distance, that is, after passing through the target crawling section distance, the elevator decelerates to zero.

[0066] Specifically, the delay distance when entering the crawling section can be determined based on the delay time and the elevator speed entering the crawling section. This delay time includes the delay time T of the leveling switch (photoelectric switch). Therefore, the delay distance V*T is obtained by multiplying the leveling switch delay time T by the elevator speed V entering the crawling section. Subtracting this delay distance from the crawling section adjustment value for the floor to be stopped yields the target crawling section distance for the floor to be stopped; that is, the target crawling section distance S for the floor to be stopped is: AV*T+D.

[0067] 205. Adjust the leveling position of the floor to be stopped based on the target crawling distance of the floor to be stopped.

[0068] After obtaining the target crawl distance to the floor where the elevator needs to stop, the leveling position of the floor can be adjusted based on this distance. Specifically, when the elevator decelerates to enter the crawl section, the initial leveling position S0 (the elevator's current position) can be recorded. The encoder can detect the signal distance between the elevator's current position and this initial leveling position. If the distance between the elevator's current position and the initial leveling position is greater than or equal to the target crawl distance to the floor where the elevator needs to stop, the elevator is controlled to decelerate and stop according to a preset deceleration curve, and the elevator's stopping position is taken as the target leveling position of the floor where the elevator needs to stop. By traversing all floors one by one, the leveling positions of all floors can be adjusted.

[0069] As can be seen, in this embodiment, the leveling distance between the elevator and the leveling position after the elevator has crawled and stopped at multiple floors is obtained; the crawling segment adjustment value for multiple floors is determined based on the leveling distance and the preset crawling segment distance; during the process of the elevator crawling and stopping at multiple floors, when the elevator decelerates to enter the crawling segment, the crawling segment adjustment value for the floor to be stopped is obtained from the crawling segment adjustment values ​​for multiple floors based on the elevator's running direction; the crawling segment adjustment value for the floor to be stopped is compensated based on the delay distance when entering the crawling segment, thus obtaining the target crawling segment distance for the floor to be stopped; the leveling position of the floor to be stopped is adjusted based on the target crawling segment distance. Adjusting the leveling position by the crawling segment adjustment value for the floor to be stopped eliminates the need to adjust the installation position of the leveling plate in the floor, making leveling adjustment more convenient and faster, and the elevator's stopping position is used as the target leveling position for the floor to be stopped.

[0071] The acquisition unit 501 is used to acquire the leveling distance between the elevator and the leveling position after the elevator has crawled and stopped at multiple floors.

[0073] The execution unit 503 is used to, during the process of the elevator crawling and stopping to the floor to be stopped on the multiple floors, when the elevator decelerates to enter the crawling section, obtain the crawling section adjustment value of the floor to be stopped from the crawling section adjustment values ​​of the multiple floors based on the running direction of the elevator.

[0074] Compensation unit 504 is used to compensate the crawling segment adjustment value of the floor to be stopped based on the delay distance when entering the crawling segment, so as to obtain the target crawling segment distance of the floor to be stopped;

[0075] The adjustment unit 505 is used to adjust the leveling position of the floor to be stopped based on the target crawling distance of the floor to be stopped.
