Description

Technical Field

[0001] This application relates to the field of elevator control, and more particularly to an elevator control method and related equipment. Background Technology

[0002] In conventional buildings such as residential and commercial buildings, elevator systems typically have fixed-length magnetic shielding plates installed in the shaft on each floor, and a leveling sensor photoelectric device installed on the car top to achieve precise leveling and stopping of the elevator. The standard magnetic shielding plate is approximately 30 centimeters long and is suitable for typical scenarios where the floor spacing is greater than 2.8 meters.

[0003] However, in special scenarios such as industrial production, to improve cargo transfer efficiency, it is often necessary to add a loading platform as an additional floor between the first and second floors. The distance between this platform and the first floor may be only 30-40 centimeters, forming an "ultra-short floor" structure. In this case, due to insufficient installation space, the magnetic shielding plates of standard length may overlap vertically on adjacent floors (such as the first floor and the loading platform floor). This causes superposition interference in the signals output by the leveling sensor, making it impossible for the elevator control system to accurately identify the positions of two adjacent floors, seriously affecting the safety and reliability of elevator operation.

[0004] In existing technologies, to solve the problem of overlapping magnetic shielding plates, the plates are typically cut on-site to shorten their length to accommodate ultra-short floor spacing. This method requires disassembling, processing, and reinstalling the already installed magnetic shielding plates, which is cumbersome, costly, and inefficient. Furthermore, the on-site construction precision is difficult to guarantee, which can easily affect the stability of the elevator's subsequent operation. Summary of the Invention

[0005] This application provides an elevator control method and related equipment to solve the problem of identifying overlapping magnetic plates on ultra-short floors, thereby improving the stability of elevator operation.

[0006] The first aspect of this application provides an elevator control method, including:

[0007] Control the elevator to run along the shaft at a self-learning speed and monitor the leveling switch signal in real time;

[0008] When the leveling switch signal changes from invalid to valid, the first pulse counter is started to accumulate and count the encoder pulses;

[0009] When the elevator reaches the area of ​​the first floor, the second pulse counter is started to accumulate the encoder pulses; when the leveling switch signal changes from valid to invalid, the value of the first pulse counter at this time is recorded as the pulse value of the second floor, and the first total pulse value of the second pulse counter from the starting position of the first floor to the second floor is recorded.

[0010] When the elevator reaches the area of ​​the third floor, the third pulse counter is started to accumulate the encoder pulses; when the leveling switch signal changes from valid to invalid again, the value of the first pulse counter at this time is recorded as the pulse value of the third floor, and the second total pulse value of the third pulse counter in the area of ​​the third floor is recorded.

[0011] Based on the pulse value of the second floor, the pulse value of the third floor, the first total pulse value, and the second total pulse value, the floor height pulse value of each floor between the first floor and the third floor is calculated, and the floor height pulse value and the pulse value corresponding to the length of the magnetic plate are stored in the elevator control system.

[0012] Optionally, calculating the floor height pulse value for each floor between the first and third floors includes:

[0013] The pulse value corresponding to the leveling position of the first floor is determined based on half of the second total pulse value;

[0014] The pulse value corresponding to the leveling position of the second floor is determined by subtracting half of the second total pulse value from the first total pulse value.

[0015] The first floor height pulse value between the first floor and the second floor is obtained by subtracting the second total pulse value from the first total pulse value.

[0016] Subtracting the pulse value of the second floor from the pulse value of the third floor yields the pulse value of the second floor height between the third floor and the second floor.

[0017] Optionally, the method further includes:

[0018] During the operation of the elevator, the current position of the elevator is corrected according to the leveling switch signal;

[0019] Specifically, when the elevator is running between the first floor and the second floor, position correction operations are prohibited.

[0020] Alternatively, when the elevator travels from the second floor to the third floor or above, and the leveling switch signal remains valid, the current position of the elevator is corrected to the sum of the leveling position of the current floor where the elevator is located and the preset correction distance.

[0021] When the elevator travels down from the third floor or above to the second floor or the first floor, and the leveling switch signal is valid, the current position of the elevator is corrected to the sum of the leveling position of the second floor and the preset correction distance.

[0022] The preset correction distance is half the pulse value corresponding to the length of the magnetic shielding plate.

[0023] Optionally, the method further includes:

[0024] When the elevator triggers a stop state and stops in the overlapping area of ​​the magnetic plates between the first floor and the second floor, the elevator is controlled to run upward at a preset leveling speed until the leveling switch signal changes from valid to invalid.

[0025] The elevator is controlled to stop running, and the downward running time of the elevator is calculated based on the stored preset correction distance, deceleration parameters and preset return-to-level speed; wherein, the preset correction distance is half of the pulse value corresponding to the length of the magnetic plate;

[0026] The elevator is controlled to travel downwards for a specified time so that it stops at the level of the second floor.

[0027] Optionally, the method further includes:

[0028] When the elevator is in normal operation and is stopped at the first or second floor, if the leveling switch signal becomes invalid, the step of controlling the elevator to run upward at a preset leveling speed is executed to control the elevator to run to the leveling position of the second floor.

[0029] Optionally, the self-learning speed includes a maintenance speed and a constant speed learning speed. The control elevator runs along the shaft at the self-learning speed and monitors the leveling switch signal in real time, including:

[0030] Control the elevator to descend to a position below the first floor at the inspection speed;

[0031] When the elevator reaches a position below the first floor, it switches to the uniform learning speed and controls the elevator to move upward to perform self-learning.

[0032] Optionally, in the structure of the ultra-short floor, the vertical distance between the first floor and the second floor is 30 to 40 centimeters;

[0033] The length of the first magnetic shielding plate of the first floor and the length of the second magnetic shielding plate of the second floor are the same as the length of the standard magnetic shielding plate, and the length of the overlapping area is not less than half the length of the standard magnetic shielding plate.

[0034] A second aspect of this application provides an elevator control system, including:

[0035] The control unit is used to control the elevator to run along the shaft at a self-learning speed and to monitor the leveling switch signal in real time.

[0036] The counting unit is used to start the first pulse counter to accumulate and count the encoder pulses when the leveling switch signal changes from invalid to valid;

[0037] The recording unit is used to start a second pulse counter to accumulate the encoder pulses when the elevator runs to the area of ​​the first floor; when the leveling switch signal changes from valid to invalid, it records the value of the first pulse counter at this time as the pulse value of the second floor, and records the first total pulse value of the second pulse counter from the starting position of the first floor to the second floor.

[0038] The recording unit is further configured to: when the elevator reaches the area of ​​the third floor, activate the third pulse counter to accumulate the encoder pulses; when the leveling switch signal changes from valid to invalid again, record the value of the first pulse counter at this time as the pulse value of the third floor, and record the second total pulse value of the third pulse counter in the area of ​​the third floor.

[0039] The calculation unit is used to calculate the floor height pulse value from the first floor to the second floor based on the second floor pulse value, the third floor pulse value, the first total pulse value and the second total pulse value, and to store the floor height pulse value and the pulse value corresponding to the length of the magnetic plate to the elevator control system.

[0040] The elevator control system provided in the second aspect of this application is used to execute the elevator control method described in the first aspect.

[0041] A third aspect of this application provides an elevator control device, comprising:

[0042] Central processing unit, memory, input / output interfaces, wired or wireless network interfaces, and power supply;

[0043] The memory is either a short-term storage memory or a persistent storage memory;

[0044] The central processing unit is configured to communicate with the memory and execute instructions in the memory to perform the elevator control method described in the first aspect.

[0045] A fourth aspect of this application provides a computer-readable storage medium including instructions that, when executed on a computer, cause the computer to perform the elevator control method described in the first aspect.

[0046] A fifth aspect of this application provides a computer program product, the computer program product including instructions that, when executed on a computer, cause the computer to perform the elevator control method described in the first aspect.

[0047] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: The elevator control method disclosed in this application utilizes a self-learning process to achieve adaptive and accurate measurement of the elevator system when the magnetic shielding plates overlap at ultra-short floors. By setting first and second pulse counters to record the total pulse and the pulse within the ultra-short floor interval, respectively, and combining the geometric relationship between the middle position of the magnetic shielding plate and the pulse, the true height pulse value of the floor corresponding to the overlapping magnetic shielding plates is innovatively derived. This method does not require physical cutting or modification of the magnetic shielding plates; it only automatically acquires and stores key floor parameters through software algorithms, completely solving the signal interference and identification problems caused by limited installation space. This provides a reliable data foundation for subsequent precise leveling control, significantly improving construction efficiency and system adaptability. Attached Figure Description

[0060] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0061] It should be noted that the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] Please see Figure 1 , Figure 1This is a diagram showing the relationship between the position of an elevator magnetic shield and the elevator floor level, as disclosed in an embodiment of this application.

[0064] Depend on Figure 1 As shown, the geometric center of each magnetic plate precisely corresponds to the standard leveling position of each floor of the elevator, which is the fundamental prerequisite for ensuring the accuracy of elevator stopping. The photoelectric switch is located at the top of the car. When the photoelectric switch is turned on, a photoelectric induction signal is generated when the photoelectric switch passes through the sensing range of the magnetic plate. Thus, the leveling detection device of the elevator control system can detect that the leveling switch signal is valid. Furthermore, when the photoelectric switch leaves the sensing range of the magnetic plate, no photoelectric induction signal is generated, that is, the leveling switch signal is invalid. In one case, the magnetic plates between different floors are fixed and identical, and the vertical height between adjacent floors is greater than the length of the magnetic plate.

[0065] However, another situation exists: ultra-short-story structure design. See details for further information. Figure 2 , Figure 2 This diagram illustrates the relationship between the elevator's magnetic shielding plate and the elevator's leveling position when the magnetic shielding plates on the first and second floors overlap, as disclosed in an embodiment of this application. Figure 2 It can be seen that, Figure 2 The design of the ultra-short floor structure between the 1st and 2nd floors is clearly shown. The standard length of the magnetic shielding plates on each floor is A, while the overlap length between the magnetic shielding plates on the 1st and 2nd floors is B. It is important to note that the geometric center of each magnetic shielding plate precisely corresponds to the standard leveling position of each elevator floor; this is a fundamental prerequisite for ensuring elevator stopping accuracy. Before the elevator is put into formal operation, the elevator control system must first complete floor data learning, a process that is crucial for subsequent control logic optimization. After all floor parameter learning tasks are completed, specific optimization processing must be carried out on the elevator control operation logic for this special ultra-short floor area between the 1st and 2nd floors to ensure the safety and stability of operation in this section.

[0066] To describe the above in detail Figure 1 and Figure 2 The relationship between the elevator magnetic shield and the elevator leveling position in this application, as well as the efforts to solve existing technical problems, can be found in [reference needed]. Figure 3 , Figure 3 This is a flowchart illustrating an elevator control method disclosed in an embodiment of this application. It includes steps 301-305.

[0067] 301. Control the elevator to run along the shaft at a self-learning speed and monitor the leveling switch signal in real time.

[0068] In this embodiment, the elevator control method is applied to an elevator control system including at least one ultra-short floor, wherein the vertical distance between the first floor and the second floor is less than the length of a standard magnetic shielding plate, resulting in an overlap area between the magnetic shielding plates of the first floor and the second floor in the vertical direction. See details [link to relevant documentation]. Figure 2 As shown. In some embodiments, the first floor, second floor, or third floor described in this embodiment are not directly equivalent to the first floor, second floor, or third floor in conventional understanding. They should be understood as three adjacent floors (e.g., the second floor, third floor, or fourth floor). However, for the convenience of illustration in this embodiment and subsequent embodiments, they can be understood as the first floor, second floor, or third floor in conventional understanding. This will not be elaborated further in the following.

[0069] In some embodiments, the commissioning personnel need to operate the maintenance switch inside the elevator control cabinet according to the standard operating procedure to switch the elevator operation mode to maintenance mode, and then issue a maintenance downlink command through the elevator control cabinet's operating interface. The elevator control system then completes the maintenance downlink command and monitors it in real time via the commissioning terminal. For easier understanding, please refer to [reference needed]. Figure 8 , Figure 8 This application discloses a diagram showing the relationship between a self-learning elevator photoelectric switch for opening the elevator shaft and the leveling positions on the 1st and 2nd floors. Figure 8 As shown, it is necessary to ensure that the elevator leveling switch signal is completely out of the sensing range of the magnetic shielding plate on the first floor. Then, after completing the above preparations, the elevator commissioning personnel send instructions to the elevator control system via a dedicated operator, causing the elevator to automatically enter the shaft learning model. At this time, the elevator control system performs maintenance in the system-preset shaft self-learning mode. Simultaneously, the elevator control system also needs to monitor the leveling switch signal in real time.

[0070] 302. When the leveling switch signal changes from invalid to valid, start the first pulse counter to accumulate and count the encoder pulses.

[0071] During elevator operation (currently moving upwards), if the leveling switch signal changes from invalid to valid (i.e., entering the sensing range of the magnetic shielding plate), the first pulse counter is activated to accumulate and count the encoder pulses.

[0072] In some embodiments, when the elevator control system detects a valid leveling switch signal via a leveling detection device, it immediately triggers a pulse accumulation mechanism, thereby starting a first pulse counter to count encoder pulses. Specifically, pulse counting and accumulation begins using a high-precision encoder signal mounted on the elevator motor shaft. The pulse counters include a first pulse counter, a second pulse counter, and a third pulse counter. The first pulse counter Cnt1 records the total number of detected pulses from the start of self-learning to the current moment; the second pulse counter Cnt2 is specifically used to record the total number of pulses during the elevator's journey from the first floor to the second floor; and the third pulse counter Cnt3 is specifically used to record the total number of pulses during the elevator's journey to the third floor. It is understood that the starting position should be interpreted as the position where the leveling switch signal changes from invalid to valid.

[0073] 303. When the elevator reaches the area of ​​the first floor, start the second pulse counter to accumulate the encoder pulses; when the leveling switch signal changes from valid to invalid, record the value of the first pulse counter at this time as the pulse value of the second floor, and record the first total pulse value of the second pulse counter from the starting position of the first floor to the second floor.

[0074] For a better understanding of the meaning of each pulse value, please refer to [link / reference]. Figure 9 , Figure 9 This is a pulse counting relationship diagram for the 1st, 2nd, and 3rd floors disclosed in an embodiment of this application. In some embodiments, the elevator continuously moves upwards. When the elevator reaches the area of ​​the first floor, i.e., enters the sensing range of the magnetic shielding plate on the first floor, the second pulse counter Cnt2 starts the encoder pulse to count. As the elevator continues to move upwards until it leaves the sensing range of the magnetic shielding plate on the second floor, the leveling switch signal changes from active to inactive. At this time, the pulse value recorded by the first pulse counter Cnt1 is recorded and marked as the second floor pulse value Floor2Cnt (see [reference]). Figure 9 Simultaneously, the first total pulse value Cnt2 of the second pulse counter is recorded from the starting position of the first floor to the second floor (see [reference]). Figure 9 ).

[0075] In some embodiments, when the system detects that the leveling switch signal changes from valid to invalid (since the magnetic shielding plates of the 1st and 2nd floors overlap, the leveling switch signal changes from valid to invalid when the leveling switch is removed from the magnetic shielding plate of the 2nd floor), the current value of the total counting pulse Cnt1 is automatically saved to the Floor2Cnt parameter storage unit, and at the same time, Cnt2 is controlled to stop the counting operation, and the elevator continues to run upward in the original running direction.

[0076] 304. When the elevator reaches the area of ​​the third floor, start the third pulse counter to accumulate the encoder pulses; when the leveling switch signal changes from valid to invalid again, record the value of the first pulse counter at this time as the pulse value of the third floor, and record the second total pulse value of the third pulse counter in the area of ​​the third floor.

[0077] In some embodiments, when the elevator continues to run and reaches the area of ​​the third floor (entering the sensing range of the magnetic shielding plate on the third floor), the third pulse counter Cnt3 is synchronously started to accumulate the encoder pulses. Then, when the elevator continues to run to a higher floor, i.e., when the leveling switch signal changes from active to inactive again (leaving the sensing range of the magnetic shielding plate on the third floor), the pulse value recorded by the first pulse counter Cnt1 at this time is recorded again and marked as the third floor pulse value Floor3Cnt (see [reference]). Figure 9 Simultaneously, the third pulse counter records the total pulse value Cnt3 from the starting position of the third floor to the point where it exits the third floor (see [reference]). Figure 9 ).

[0078] In some embodiments, when the elevator continues to move upwards to the 3rd floor, and the leveling detection device detects the leveling switch signal is valid again, the third pulse counter Cnt3 starts counting. After the leveling switch signal becomes invalid again, the real-time value of the total count pulses Cnt1 is saved to the Floor3Cnt parameter storage unit, and the third pulse counter Cnt3 is controlled to stop counting. If the total number of floors in the elevator is configured to be 3, the elevator control system will immediately execute a deceleration and stopping procedure. If the number of floors in the elevator exceeds 3, the elevator continues to move upwards at the self-learning speed until it reaches the top floor of the building. When the leveling switch signal leaves the invalid state (i.e., completely exceeds the sensing range of the top floor magnetic plate), the entire shaft self-learning process automatically stops.

[0079] 305. Based on the pulse value of the second floor, the pulse value of the third floor, the first total pulse value, and the second total pulse value, calculate the floor height pulse value of each floor between the first and third floors, and store the floor height pulse value and the pulse value corresponding to the length of the magnetic plate to the elevator control system.

[0080] In some embodiments, by combining the second floor pulse value, the third floor pulse value, the first total pulse value, and the second total pulse value obtained as described above, the floor height pulse value for each floor can be obtained. Simultaneously, the pulse value corresponding to the length of the magnetic shielding plate can also be obtained synchronously. Finally, the calculated floor height pulse signals are stored in a designated parameter area of ​​the system memory. See details in [link to relevant documentation]. Figure 4 The illustrated embodiment.

[0081] This embodiment discloses an elevator control method that, through a self-learning process, enables the elevator control system to automatically identify and record the leveling position of each floor, the sensing range of the magnetic shielding plate, and the pulse count value. For ultra-short floors with overlapping magnetic shielding plates, the floor height pulse value can be accurately obtained through the coordinated counting of a second pulse counter and a third pulse counter. This allows for structural modeling of the overlapping area at the software level, eliminating the need for physical cutting or structural adjustment of the magnetic shielding plates. Furthermore, the elimination of on-site cutting of the magnetic shielding plates avoids tedious processes such as disassembly, processing, and reinstallation, saving significant labor, tool, and time costs. It also reduces the risk of secondary debugging or malfunctions caused by insufficient on-site construction accuracy, improving the overall reliability of the system and lowering subsequent maintenance costs. Moreover, this embodiment is entirely based on software algorithms, requiring no modification to the hardware structure, and is suitable for upgrading and retrofitting various existing or newly built elevator systems. Through intelligent processing of pulse counting and signal logic, it can adapt to different floor structures (especially ultra-short floors), enhancing the elevator's applicability in special environments such as industrial settings. The floor height pulse value and magnetic plate pulse length value acquired through self-learning are not only the foundation of leveling control, but also provide key parameters for advanced functions such as return-to-level processing, fault recovery, and speed curve planning.

[0082] For step 305, the specific method for calculating the floor height pulse value from the first floor to the second floor can be found in [reference needed]. Figure 4 , Figure 4 This is a flowchart illustrating another elevator control method disclosed in an embodiment of this application. It includes steps 401-404.

[0083] 401. Determine the pulse value corresponding to the leveling position of the first floor based on half of the second total pulse value.

[0084] Continue reading Figure 9 As shown, the elevator control system obtains the floor height pulse Height1to2 from the 1st floor to the 2nd floor through a preset algorithm model and the calculation method of this embodiment.

[0085] In some embodiments, the pulse value corresponding to the leveling position of the first floor can be determined based on half of the second total pulse value Cnt3. First, the pulse value corresponding to the leveling position of the first floor is calculated by Cnt3 / 2. This is because the length of the magnetic shielding plate on the first floor is the same as the length of the magnetic shielding plates on the second and third floors. The middle position of each magnetic shielding plate is the leveling position of each floor. Therefore, Cnt3 / 2 corresponds to the leveling position of the first floor. This value is derived from the correspondence between the middle position of the magnetic shielding plate and the pulse count.

[0086] 402. Determine the pulse value corresponding to the leveling position of the second floor by subtracting half of the second total pulse value from the first total pulse value.

[0087] In some embodiments, since the magnetic shielding plates of the second floor overlap with those of the first floor, and the pulse value corresponding to the leveling position of the first floor is half of the second total pulse value, the pulse value corresponding to the leveling position of the second floor is half of the first total pulse value minus the second total pulse value, i.e., Cnt2 minus Cnt3 / 2.

[0088] 403. Subtract the second total pulse value from the first total pulse value to obtain the first floor height pulse value between the first floor and the second floor.

[0089] In some embodiments, as can be seen from the above description, the floor height pulse (first floor height pulse value) Height1to2 of the first floor and the second floor is the first total pulse value minus the second total pulse value, i.e., Cnt2-Cnt3.

[0090] 404. Subtract the pulse value of the second floor from the pulse value of the third floor to obtain the pulse value of the second floor height between the third floor and the second floor.

[0091] In some embodiments, combined with Figure 9 As shown, the floor height pulse value between the second and third floors is the third floor pulse value minus the second floor pulse value. It can be understood that the floor height pulse between the 2nd and 3rd floors is obtained by the difference between Floor3Cnt and Floor2Cnt. Similarly, the height pulse between the 3rd and 4th floors and above can be calculated by the difference in floor parameters between adjacent floors. This process can be repeated to obtain complete height pulse data between all elevator floors.

[0092] This embodiment discloses an elevator control method that solves the problem of inability to directly measure floor height due to overlapping magnetic shielding plates under traditional installation conditions. By cleverly utilizing the consistent length of standard magnetic shielding plates, the leveling position of the first floor is derived from the pulse measurement value (Cnt3 / 2) of the third floor. Then, combined with the total pulse difference (Cnt2-Cnt3) between the first and second floors, the height pulse value between them is accurately calculated. This achieves precise mathematical modeling and parameter extraction of the overlapping area without changing the hardware layout. This method not only avoids the cumbersome operation of physically cutting or reinstalling the magnetic shielding plates, but also ensures that the measurement process is fully automated, repeatable, and independent of manual intervention, significantly reducing installation and commissioning costs and construction risks. The acquired floor height pulse data is accurate and reliable, providing core parameter basis for subsequent elevator operation control, leveling signal correction, and safe stopping, comprehensively improving the adaptability, control accuracy, and long-term operational stability of the elevator system under special structures.

[0093] For step 301, its self-learning speed can be found in [reference needed]. Figure 5 , Figure 5This is a flowchart illustrating another elevator control method disclosed in an embodiment of this application. It includes steps 501-502.

[0094] 501. Control the elevator to descend to a position below the first floor at inspection speed.

[0095] In some embodiments, after switching the elevator operation mode to maintenance mode, a maintenance descent command needs to be issued through the control cabinet operation interface. The elevator is controlled to run smoothly downwards at a preset maintenance speed. When the elevator reaches the first floor area, real-time monitoring via a debugging terminal is required to ensure that the elevator leveling switch signal is completely out of the sensing range of the first-floor magnetic plate (specific status as follows). Figure 8 (As shown).

[0096] 502. When the elevator reaches a position below the first floor, switch to a constant speed learning speed and control the elevator to move upward to perform self-learning.

[0097] In some embodiments, when the elevator reaches a position below the first floor, the elevator control system will control the elevator to move upward at a constant speed using a preset shaft self-learning speed.

[0098] As described above, the elevator control system first controls the maintenance elevator to descend, and then begins learning to go to the top floor.

[0099] The elevator control method disclosed in this embodiment ensures the accuracy and consistency of the self-learning process. By first controlling the elevator to descend until the signal from the magnetic plate is completely disengaged, and then switching to uniform upward movement, interference from overlapping signal intervals on the initial count is effectively avoided. This establishes a reliable reference starting point for the accurate acquisition of subsequent pulse counts and ensures the standardization of the initial conditions for learning the floor height parameters.

[0100] Completed Figures 3 to 5 Following the illustrated embodiment, a planarization signal correction step is also required; please refer to [link / reference needed]. Figure 6 , Figure 6 This is a flowchart illustrating another elevator control method disclosed in an embodiment of this application. It includes steps 601-604.

[0101] 601. During elevator operation, the current position of the elevator is corrected according to the leveling switch signal.

[0102] In some embodiments, the above Figures 3 to 5 The illustrated embodiment can be understood as step 1 of the overall elevator control system, namely the shaft self-learning process. In this embodiment, it is understood as step 2 of the overall elevator control system, namely the correction process of the leveling signal correction logic.

[0103] In some embodiments, the elevator leveling switch signal primarily serves as a floor data correction function in elevator operation control, eliminating accumulated position errors during elevator operation. For elevator systems using a single leveling switch, the standard value of the correction distance is set to half the pulse signal corresponding to the length A of the magnetic plate. Specifically, the correction rule is as follows: when the elevator is in an upward motion, the current position correction is the floor leveling position plus the correction distance; when the elevator is in a downward motion, the current position correction is the floor leveling position minus the correction distance. It can be understood that half the pulse signal corresponding to the length A of the magnetic plate in this embodiment can be found in [reference needed]. Figure 5 The illustrated embodiment shows the pulse value recorded by Cnt3.

[0104] In some embodiments, steps 602 to 604 can be executed separately depending on the different operating states of the elevator during operation.

[0105] 602. Position correction operations are prohibited when the elevator is running between the first and second floors.

[0106] In some embodiments, for elevators with a 1-2 floor ultra-short-floor structure, the magnetic shielding plates on the 1st and 2nd floors overlap in length within this section, resulting in a unique induction state for the leveling switch signal. Conventional position correction can easily lead to errors. Therefore, in this embodiment, the elevator control system does not perform any position correction operations during the elevator's movement from the 1st floor to the 2nd floor, or vice versa, to avoid correction logic conflicts.

[0107] 603. When the elevator moves from the second floor to the third floor or above, and the leveling switch signal remains valid, the current position of the elevator is corrected to the sum of the leveling position of the elevator on the current floor and the preset correction distance.

[0108] In some embodiments, when the elevator travels from the 2nd floor to the 3rd floor or above, if the leveling switch does not detect an invalid signal (i.e., the signal remains in a normal sensing state or remains valid), since the magnetic plates on the 2nd and 3rd floors will not overlap, only the 1st and 2nd floors will overlap. Therefore, the elevator control system needs to correct the current position to the leveling position of the current floor plus the standard correction distance according to the preset logic to ensure the position accuracy during the subsequent upward movement.

[0109] Furthermore, in some embodiments, when the leveling switch malfunctions while the elevator is traveling from the 3rd floor or above, the elevator control system will perform differentiated corrections based on the direction of travel. For example, if the elevator is traveling upwards, the current position will be corrected to the current floor leveling position plus the correction distance. If the elevator is traveling downwards, the current position will be corrected to the current floor leveling position minus the correction distance, in order to quickly restore positional accuracy.

[0110] Furthermore, in some embodiments, when the elevator is running on the 2nd floor or above, when the elevator control system controls the elevator to decelerate to the magnetic plate sensing area of ​​the target floor, and the leveling switch signal is valid, the following position correction strategies can also be executed. For example, when the elevator is ascending and approaching the target floor, the current position is corrected to the distance to the floor ahead minus the correction distance. Alternatively, when the elevator is descending and approaching the target floor, the current position is corrected to the distance to the floor ahead plus the correction distance, ensuring that the elevator accurately stops at the leveling position of the target floor.

[0111] The difference between the above-mentioned position corrections can be understood as follows: one operates within a floor, while the other operates from one floor to another.

[0112] 604. When the elevator travels down from the third floor or above to the second floor or the first floor, and the leveling switch signal is valid, the current position of the elevator is corrected to the sum of the leveling position of the second floor and the preset correction distance.

[0113] In some embodiments, when the elevator runs from the 3rd floor or above to the 2nd floor or the 1st floor, when the elevator control system controls the elevator to decelerate to the magnetic plate sensing area of ​​the target stopping floor, and the leveling switch signal is valid, in order to avoid signal interference in the ultra-short floor interval, the current position needs to be uniformly corrected to the 2nd floor leveling position plus the correction distance, and then subsequent fine-tuning is performed according to the final target floor.

[0114] This embodiment discloses an elevator control method that effectively solves the signal interference and misjudgment problems caused by overlapping magnetic shielding plates in ultra-short floor areas. By dynamically adjusting the correction logic according to the operating intervals: correction is prohibited in overlapping intervals to avoid error accumulation; standard pulse offset compensation is used in normal floor areas; and correction is uniformly performed based on the second floor when descending to the overlapping area. This method ensures the elevator's positional accuracy throughout its journey while intelligently avoiding signal conflict areas, achieving a smooth control transition between overlapping and non-overlapping areas. This significantly improves the elevator's operational stability and stopping accuracy under special structures, ensuring the safe and reliable operation of the system.

[0115] Completed Figures 3 to 6 Following the illustrated embodiment, it is also necessary to perform the fault or repair leveling procedure and the leveling switch failure leveling procedure, which can be referred to in [reference needed]. Figure 7 , Figure 7 This is a schematic flowchart of another elevator control method disclosed in an embodiment of this application. It includes steps 701-704.

[0116] 701. When the elevator triggers a stop state and stops in the overlapping area of ​​the magnetic plates between the first and second floors, control the elevator to run upwards at a preset leveling speed until the leveling switch signal changes from valid to invalid.

[0117] In this embodiment, steps 3 and 4 of the elevator control system are understood as the overall process of handling faults and maintenance return-to-leveling (step 3) and the process of handling invalid return-to-leveling switches (step 4). In some embodiments, steps 701-703 are step 3 of the overall elevator control system.

[0118] In some embodiments, when the elevator stops due to a sudden malfunction or is under maintenance, if it unexpectedly stops within the effective leveling zone between the 1st and 2nd floors (i.e., the overlapping area of ​​the magnetic plates between the first and second floors), the leveling switch signal cannot accurately reflect the elevator's actual leveling position because the magnetic plates in this zone overlap. In this case, the elevator control system will activate an automatic return-to-level emergency procedure. This procedure first controls the elevator to run upwards at a preset automatic return-to-level speed (preset return-to-level speed). Simultaneously, the leveling detection device continuously monitors the signal status of the leveling switch signal until it detects that the leveling switch signal has changed from valid to invalid.

[0119] 702. Control the elevator to stop running, and calculate the elevator's downward running time based on the stored preset correction distance, deceleration parameters and preset return-to-level speed.

[0120] In some embodiments, after detecting that the leveling switch signal has changed from valid to invalid, the elevator control system immediately stops the elevator from moving upwards. Subsequently, the elevator control system automatically calculates the required downward travel time using a motion control algorithm based on pre-stored leveling correction distance A / 2 (see Cnt3 / 2 above), elevator deceleration parameters, and automatic return-to-level speed. It can be understood that, assuming the return-to-level speed V, the downward travel time... Since the leveling speed is very low, the distance from V to 0 can be ignored.

[0121] 703. Control the elevator's downward movement and the downward movement time so that the elevator stops at the level position on the second floor.

[0122] In some embodiments, based on the results of the above calculations, the elevator is controlled to execute downward movement control logic with downward movement time and return-to-level speed, thereby ensuring that the elevator can accurately stop at the standard level position on the 2nd floor each time it performs a return-to-level operation.

[0123] 704. When the elevator is in normal operation and is stopped at the first or second floor, if the leveling switch signal becomes invalid, the elevator is controlled to move upward at a preset leveling speed to control the elevator to move to the leveling position of the second floor.

[0124] In some embodiments, when the elevator triggers a stop state, that is, when it is normally stopped at the 1st or 2nd floor (generally referring to the overlapping area of ​​the magnetic plate between the 1st and 2nd floors, or the floor area of ​​the 1st or 2nd floor), the leveling switch signal may become invalid due to factors such as slight shaking of the elevator car caused by people entering and exiting the elevator car or loading and unloading goods. In order to avoid the elevator from malfunctioning due to abnormal position signal, the elevator control system will uniformly follow the above-mentioned automatic return leveling method to control the elevator to return to the 2nd floor for leveling operation, so as to quickly restore the elevator's normal stopping state.

[0125] This embodiment discloses an elevator control method that effectively solves the reset problem when an elevator is stuck in an overlapping area of ​​an ultra-short floor due to a malfunction or signal loss. By first controlling the elevator to run upwards until it leaves the overlapping signal area, and then accurately calculating and executing the downward running time based on preset motion parameters, the elevator can be reliably guided and stopped at the standard leveling position on the second floor. This method is not only applicable to malfunction and maintenance states, but can also be automatically triggered during normal stops due to signal interference, ensuring that the elevator can quickly and safely return to a known precise position under various abnormal conditions. This greatly improves the robustness, safety, and availability of the system, avoiding the risks and delays of manual intervention.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
