[0001] The present application relates to the elevator control technical field, and particularly to an elevator mislanding correction method, device, equipment and computer readable storage medium. BACKGROUND

[0002] At present, the elevator is prone to skidding in the case of emergency stop, which leads to the control system being unable to accurately determine the stop position of the elevator, and the mislanding occurs. After the mislanding occurs, the floor can be corrected only after the elevator runs to the terminal station, or the floor can be corrected by means of the absolute position device. In the two ways of correcting the floor, the former seriously affects the normal use of the elevator, and the latter needs to install the absolute position device, which is high in cost and low in applicability. SUMMARY

[0016] Optionally, the step of correcting the emergency stop position of the elevator according to the running direction of the elevator immediately before the emergency stop comprises:

[0017] If the elevator is traveling in an upward direction immediately before the emergency stop, the emergency stop position of the elevator is corrected to the lower of the two adjacent floors of the elevator;

[0018] If the running direction of the elevator is downward at the moment before the emergency stop, the emergency stop position of the elevator is corrected to the higher floor of the two adjacent floors of the elevator.

[0039] In the following description, specific details such as specific system structures and technologies are provided for illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the embodiments of the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the embodiments of the present application.

[0041] It should also be understood that references to "one embodiment" or "some embodiments" described in the description of the embodiments of the present application mean that one or more embodiments of the embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Thus, the phrases "in one embodiment," "in some embodiments," "in some other embodiments," "in some other embodiments," etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.

[0042] Currently, elevators are prone to slipping during emergency stops, causing the control system to be unable to accurately determine the elevator's stopping position, resulting in a misaligned floor. When this occurs, the floor can generally be corrected only after the elevator reaches the terminal station, or with the help of an absolute positioning device. Of these two methods, the former severely impacts the elevator's normal operation, while the latter requires the installation of an absolute positioning device, which is costly and less practical.

[0043] Based on this, the embodiment of the present application provides an elevator staggered floor correction method, device, equipment and computer-readable storage medium. When the elevator stops suddenly and a staggered floor occurs, there is no need to use an absolute positioning device or go to the terminal station. As long as it stops at the nearest door zone position, the floor can be corrected, saving economic costs and improving the efficiency of elevator use. In the elevator staggered floor correction method provided in the embodiment of the present application, after the elevator emergency stop is detected, the emergency stop position of the elevator is first recorded; then, according to the door zone signal of the elevator, the number of floors passed by the elevator during the sliding process is recorded; when the elevator stops sliding and returns to the leveling floor, the current floor number of the elevator can be modified according to the emergency stop position and the number of floors passed by the elevator during the sliding process. Therefore, by implementing the elevator staggered floor correction method provided by the present application, the floor can be corrected after the elevator returns to the leveling floor, without going to the terminal station, improving the correction efficiency after the elevator staggers, thereby reducing the risk of elevator use and improving the safety of the elevator; and the present application does not require the elevator to be equipped with an absolute positioning device, saving economic costs.

[0044] The elevator staggered floor correction method, device, equipment and computer-readable storage medium provided in the embodiments of the present application are specifically illustrated through the following embodiments. First, the elevator staggered floor correction method in the embodiments of the present application is described.

[0045] The present application provides a method for correcting staggered floors in an elevator. Figure 1 , Figure 1 A flowchart of an elevator staggered floor correction method provided in an embodiment of the present application is provided. The elevator staggered floor correction method can be applied to an elevator staggered floor correction device, such as Figure 1 As shown, the elevator staggered floor correction method provided in this embodiment includes steps S10 to S30.

[0046] Step S10, after detecting an emergency stop of the elevator, recording the emergency stop position of the elevator;

[0047] It should be noted that the execution subject in the embodiment can be an elevator control system in the elevator mislanding correction device. After detecting the elevator emergency stop, the system can capture the elevator event through the change of the emergency stop identification bit, or capture the event through the state change of some hardware mechanism for implementing the emergency stop on the elevator. After obtaining the information of the elevator emergency stop, the system records the current position of the elevator as the emergency stop position.

[0048] Further, in some possible embodiments, after step S10, the elevator mislanding correction method can further include but is not limited to the following steps:

[0049] Step S11, determining whether the emergency stop position is between floors.

[0050] Further, in some possible embodiments, step S11 can include but is not limited to the following steps:

[0051] Step S111, if the levelling signal is detected, determining that the emergency stop position is not between floors;

[0052] Step S112, if the levelling signal is not detected, determining that the emergency stop position is between floors.

[0053] It should be understood that there can be two different cases of the emergency stop position recorded by the system, i.e., the elevator stops between floors or the elevator does not stop between floors. The case that the elevator does not stop between floors means that the system can detect the levelling signal at this time, indicating that the elevator is just levelled with a floor. The case that the elevator stops between floors means that the system cannot detect the levelling signal at this time, indicating that the elevator is not levelled with any floor.

[0054] Further, in some possible embodiments, after step S11, the elevator mislanding correction method can further include but is not limited to the following steps:

[0055] Step A10, if the emergency stop position is between floors, correcting the emergency stop position of the elevator according to the running direction of the elevator at a time before the emergency stop;

[0056] Step B10, if the emergency stop position is not between floors, recording the emergency stop position of the elevator as the floor corresponding to the levelling signal.

[0057] It should be understood that the way of recording the emergency stop position will be different according to the position of the elevator at the time of emergency stop. If the emergency stop position of the elevator corresponds to a floor, the floor can be recorded as the emergency stop position without any dispute. However, if the emergency stop position of the elevator is between two floors, there will be a dispute on which adjacent floor to be taken as the emergency stop position.

[0058] Furthermore, in some feasible embodiments, the step of correcting the emergency stop position of the elevator according to the running direction of the elevator immediately before the emergency stop in step A10 may include but is not limited to the following steps:

[0059] Step A101: If the elevator is traveling in an upward direction immediately before the emergency stop, the emergency stop position of the elevator is corrected to the lower of the two adjacent floors of the elevator.

[0060] Step A102: If the elevator is running in a downward direction immediately before the emergency stop, the emergency stop position of the elevator is corrected to the higher floor of the two adjacent floors of the elevator.

[0061] It should be noted that in the case where the elevator's emergency stop position is between two floors, this embodiment will correct the elevator's emergency stop position based on the elevator's running direction before the emergency stop so that it can also correspond to a certain floor, rather than vaguely determining that it is between two floors. If the elevator's running direction before the emergency stop is upward, and the elevator is between two floors after the emergency stop, the elevator's emergency stop position will be determined to be the lower of the two adjacent floors, that is, the floor the elevator has passed, not the floor the elevator has not yet reached. Similarly, if the elevator's running direction before the emergency stop is downward, and the elevator is between two floors after the emergency stop, the elevator's emergency stop position will be determined to be the higher of the two adjacent floors. Obviously, when the elevator is descending, the higher floor corresponds to the floor the elevator has passed, and the lower floor corresponds to the floor the elevator has not yet reached.

[0062] Step S20, recording the number of floors passed by the elevator during the sliding process according to the door zone signal of the elevator;

[0063] It should be noted that no matter what operating state the elevator is in, the system can obtain the elevator's door area signal in real time. After the elevator starts to slide due to the inertia generated by the emergency stop, the door area signal can still be used as a basis for determining whether the elevator has passed a certain floor. Therefore, the number of floors passed by the elevator during the sliding process can be known and recorded based on the door area signal.

[0064] Furthermore, in some feasible embodiments, the step of recording the number of floors passed by the elevator during the sliding process according to the door zone signal of the elevator in step S20 may include but is not limited to the following steps:

[0065] Step S21, counting the magnetic isolation plates that the elevator slides over according to the signal state of the door zone signal, and using the count result as the number of floors the elevator passes during the sliding process;

[0066] If the running direction of the elevator before the emergency stop is upward, and the signal state is that the upper door zone changes from invalid to valid and the lower door zone is invalid, it means that the elevator is sliding upward and the state of the upper door zone detection part changes from not being shielded by the shielding plate to being shielded by the shielding plate, so the counting result is increased by one; if the signal state is that the upper door zone changes from valid to invalid and the lower door zone is invalid, it means that the elevator is sliding downward and the state of the upper door zone detection part changes from being shielded by the shielding plate to not being shielded by the shielding plate, so the counting result is decreased by one.

[0067] If the running direction of the elevator before the emergency stop is downward, and the signal state is that the lower door zone changes from invalid to valid and the upper door zone is invalid, it means that the elevator is sliding downward and the state of the lower door zone detection part changes from not being shielded by the shielding plate to being shielded by the shielding plate, so the counting result is increased by one; if the signal state is that the lower door zone changes from valid to invalid and the upper door zone is invalid, it means that the elevator is sliding upward and the state of the lower door zone detection part changes from being shielded by the shielding plate to not being shielded by the shielding plate, so the counting result is decreased by one.

[0068] It should be understood that, during the sliding process of the elevator, the judgment of whether the elevator passes a certain floor based on the door zone signal is different from that during normal operation of the elevator. In this embodiment, whether the elevator slides through a certain floor is judged based on the change of the signal state of the door zone signal, and the state of the door zone signal is related to whether the detection part is shielded by the shielding plate, so in this embodiment, the shielding plate through which the elevator slides can be counted according to the change of the state of the door zone signal, and the counting result is equivalent to the number of floors through which the elevator passes during the sliding process. The door zone signal includes an upper door zone signal and a lower door zone signal, and the signal state of the upper door zone signal and the lower door zone signal includes a valid state and an invalid state. When the signal is at a high level, it is considered to be in a valid state, and when the signal is at a low level, it is considered to be in an invalid state.

[0069] If the running direction of the elevator before the emergency stop is upward, and the signal state is that the upper door zone changes from invalid to valid and the lower door zone is invalid, it means that the elevator is sliding upward and the state of the upper door zone detection part changes from not being shielded by the shielding plate to being shielded by the shielding plate, so the counting result is increased by one; if the signal state is that the upper door zone changes from valid to invalid and the lower door zone is invalid, it means that the elevator is sliding downward and the state of the upper door zone detection part changes from being shielded by the shielding plate to not being shielded by the shielding plate, so the counting result is decreased by one.

[0070] Similarly, if the running direction of the elevator before the emergency stop is downward, and the signal state is that the lower door zone changes from invalid to valid and the upper door zone is invalid, it means that the elevator is sliding downward and the state of the lower door zone detection part changes from not being shielded by the shielding plate to being shielded by the shielding plate, so the counting result is increased by one; if the signal state is that the lower door zone changes from valid to invalid and the upper door zone is invalid, it means that the elevator is sliding upward and the state of the lower door zone detection part changes from being shielded by the shielding plate to not being shielded by the shielding plate, so the counting result is decreased by one.

[0071] Step S30, when the elevator stops sliding and returns to the leveling, the number of floors currently located by the elevator is modified according to the emergency stop position and the number of floors through which the elevator passes during the sliding process.

[0072] It can be understood that when the elevator stops sliding and returns to the leveling floor, it means that the elevator has resumed normal operation from the emergency stop state, and the system has regained the ability to accurately control the elevator. At this time, the floor number corresponding to the current leveling floor of the elevator can be calculated based on the emergency stop position of the elevator recorded after the emergency stop and the number of floors passed by the elevator during the sliding process, without returning to the terminal station to reset the floor number.

[0073] Furthermore, in some feasible embodiments, the step of modifying the current floor number of the elevator according to the emergency stop position and the number of floors passed by the elevator during the sliding process in step S30 may include but is not limited to the following steps:

[0074] Step S31: If the elevator was traveling in an upward direction immediately before the emergency stop, the current floor number of the elevator is modified to the sum of the floor corresponding to the emergency stop position and the number of floors the elevator has passed during the sliding process.

[0075] Step S32: If the elevator is running downward just before the emergency stop, the floor number where the elevator is currently located is modified to the difference between the floor corresponding to the emergency stop position and the number of floors the elevator has passed during the sliding process.

[0076] In this embodiment, it is also necessary to discuss the situation separately according to the running direction of the elevator before the emergency stop. If the running direction of the elevator before the emergency stop is upward, then after the elevator is restored to the leveling after the emergency stop and returns to normal operation, the floor corresponding to the current leveling is modified to the position before slipping (i.e., the emergency stop position) plus the number of magnetic isolation plates that have slid (i.e., the number of floors the elevator has slid past), and the floor can be corrected; if the running direction of the elevator before the emergency stop is downward, then after the elevator is restored to the leveling after the emergency stop and returns to normal operation, the floor corresponding to the current leveling is modified to the position before slipping (i.e., the emergency stop position) minus the number of magnetic isolation plates that have slid (i.e., the number of floors the elevator has slid past), and the floor can be corrected.

[0077] For example, in the above embodiments, if the elevator is moving upward before emergency stop, Figure 2 To understand, Figure 2 This is a schematic diagram of an application scenario of an elevator upward emergency stop involving an elevator staggered floor correction method provided in this embodiment, Figure 2It can be seen that when the elevator is going up, if the elevator stops suddenly, the current floor is recorded. If it is between floors, it is recorded as the lower floor. For example, if it is between the 3rd and 4th floors, the emergency stop position is recorded as the 3rd floor. During the sliding process caused by the emergency stop, the number of magnetic isolation plates that slid before returning to normal is recorded. Specifically, the number of magnetic isolation plates that have slid can be judged based on the door zone signal. When the upper door zone is at a rising edge (that is, the upper door zone signal changes from a low level to a high level, from invalid to valid), the lower door zone is invalid, and the count is increased by 1. When the upper door zone is at a falling edge (that is, the upper door zone signal changes from a high level to a low level, from valid to invalid), the lower door zone is invalid, and the count is reduced by 1. After the door zone returns to normal, the current floor is corrected to the position before the slip plus the number of magnetic isolation plates that have slid, and the elevator staggered floor correction is completed. Figure 2 The figure also shows the relative position relationship between the upper door zone detection unit and the lower door zone detection unit for detecting door zone signals and the elevator car and the magnetic isolation plate. If the elevator is sliding upward, the count is increased by 1 when the upper door zone changes from invalid to valid and the lower door zone is invalid; if the elevator is sliding downward, the count is decreased by 1 when the upper door zone changes from valid to invalid and the lower door zone is invalid.

[0078] For example, in the above embodiments, if the elevator is in a downward direction before emergency stop, Figure 3 To understand, Figure 3 This is a schematic diagram of an application scenario of an elevator down emergency stop involving an elevator staggered floor correction method provided in this embodiment. Figure 3 It can be seen that when the elevator is descending, if the elevator stops suddenly, the current floor is recorded. If it is between floors, it is recorded as the upper floor. For example, if it is between the 3rd and 4th floors, the emergency stop position is recorded as the 4th floor. During the sliding process caused by the emergency stop, the number of magnetic isolation plates that have slid before returning to normal is recorded. Specifically, the number of magnetic isolation plates that have slid can be judged based on the door zone signal. When the lower door zone is at the rising edge (that is, the lower door zone signal changes from low level to high level, from invalid to valid), the upper door zone is invalid, and the count is increased by 1. When the lower door zone is at the falling edge (that is, the lower door zone signal changes from high level to low level, from valid to invalid), the upper door zone is invalid, and the count is reduced by 1. After the door zone returns to normal, the current floor is corrected to the position before the slip minus the number of magnetic isolation plates that have slid, and the elevator staggered floor correction is completed. Figure 3 The figure also shows the relative position relationship between the upper door zone detection unit and the lower door zone detection unit used to detect the door zone signal and the elevator car and the magnetic isolation plate. If the elevator is sliding downward, the count is increased by 1 when the lower door zone changes from invalid to valid and the upper door zone is invalid; if the elevator is sliding upward, the count is decreased by 1 when the lower door zone changes from valid to invalid and the upper door zone is invalid.

[0079] This embodiment provides a method for correcting an elevator staggered floor. After detecting an elevator emergency stop, the method first records the elevator's emergency stop position; then, based on the elevator's door zone signal, records the number of floors the elevator has passed during its sliding process; when the elevator stops sliding and returns to leveling, the number of floors the elevator is currently on can be modified based on the emergency stop position and the number of floors the elevator has passed during its sliding process. Thus, by implementing the elevator staggered floor correction method provided by this application, the floor can be corrected after the elevator returns to leveling without having to go to the terminal station, thereby improving the efficiency of correcting staggered floors, thereby reducing the risk of elevator use and improving the safety of the elevator. Furthermore, this application does not require the elevator to be equipped with an absolute positioning device, saving economic costs. Compared to the prior art, this embodiment does not require the use of an absolute positioning device or the need to go to the terminal station when the elevator stops suddenly and staggers. Instead, the elevator can correct the floor by simply stopping at the nearest door zone position and calculating the floor based on the position recorded when the elevator stopped suddenly and the number of magnetic isolation plates it has passed. This saves economic costs and improves the efficiency of elevator use.

[0080] In addition, the embodiment of the present application also proposes an elevator staggered floor correction device, referring to Figure 4 , Figure 4 This is a structural diagram of an elevator staggered floor correction device provided in one embodiment of the present application, as shown in FIG.

[0099] if the running direction of the elevator at the time before the emergency stop is upward, modify the number of the floor where the elevator is currently located to the sum of the floor corresponding to the emergency stop position and the number of floors passed by the elevator during the sliding process;
