For example, maintenance personnel regularly or irregularly test the automatic closing function of the floor door on each floor to determine whether it is functioning normally. The inspection work will consume a lot of manpower and time, especially for elevator systems running in high-rise and super high-rise buildings. Summary of the invention

In the method for detecting the automatic closing function of a floor door according to one aspect of the present application, when a car of an elevator system stops at one of a plurality of floors, the car door of the car and the floor door associated with the one of the floors are opened. Subsequently, during the closing process of the floor door, the driving mechanism of the elevator system applies a balanced driving force to the car door of the car.

In addition, the relationship curve can be calibrated regularly or irregularly.

[0009] Optionally, whether the self-locking mechanism starts to act is determined based on at least one of the following: a sensing signal from a sensor that monitors the movement of the self-locking mechanism, a current flowing through the self-locking mechanism, and a signal from a position feedback device of the self-locking mechanism.

[0010] Optionally, the preset time period is determined according to the movement speed and position of the landing door when the balancing driving force starts to be applied.

[0022] The present application is described more fully below with reference to the accompanying drawings in which illustrative embodiments of the present application are illustrated. However, the present application may be implemented in different forms and should not be interpreted as being limited to the embodiments given herein. The above embodiments are given to make the disclosure herein comprehensive and complete, so as to more fully convey the scope of protection of the present application to those skilled in the art.

[0023] In this specification, terms such as "comprise" and "include" indicate that in addition to the units and steps directly and explicitly stated in the specification and claims, the technical solution of the present application does not exclude the situation where there are other units and steps that are not directly or explicitly stated.

[0024] In this specification, "closing process" refers to the process from when the car door or floor door starts to move until it is normally closed or reaches a closed state. During the closing process, the car door or floor door will gradually reduce the gap between the doors. The normal closing or closed state mentioned here means that the car door or floor door is completely closed without any gap or opening. It should be pointed out that the gap mentioned here can refer to the gap between door bodies (when the door includes multiple door bodies), or it can refer to the gap between the door body and the door frame (when the door includes only one door body).

[0025] In this specification, "automatic closing function of floor doors" refers to the function of prompting the floor doors to close, prohibiting the floor doors from opening, or locking the floor doors when the elevator system is in a specific state (for example, the car is in a parked state and the floor doors are completely closed). It should be pointed out that the implementation of the automatic closing function of floor doors depends on the coordinated operation of multiple levels and multiple components. For example, with respect to the floor doors of the elevator system, the control device (such as a door controller or an elevator controller) will monitor the status of each floor door and the position of the car, and determine the timing of locking the floor door based on the monitoring information; for another example, the door sensor or the door lock switch is responsible for transmitting the status signal of the floor door (such as the door closed position signal) to the control device; for another example, the actuator, as a key component, usually executes the action of closing, locking or unlocking the floor door based on the instructions of the control device. In other words, any abnormal operation of any level or component may cause an abnormality in the automatic closing function of the floor door.

[0026] The specific structure and working principle of the actuator may vary depending on the elevator manufacturer and product model. It usually includes components such as spring devices and / or gravity hammers to ensure the normal operation of the self-locking function or automatic closing function. For example, in a typical actuator, when the floor door is in a closed state, the spring will apply a certain force to the floor door to drive the floor door into a fully closed state and keep the floor door closed. The gravity hammer (safetygear) is another component in the actuator. When the car is in a parked state, the gravity hammer can drive the floor door into a fully closed state and keep the floor door locked. It should be noted that it is usually not necessary to configure a separate gravity hammer for each floor door; in addition, a spring can be configured separately for each floor door, or a set of shared spring systems can be used to support multiple floor doors of the elevator system.

[0027] In some embodiments of the present application, the automatic closing function of the landing door is checked by making the elevator system enter the automatic checking mode. The automatic closing function of the landing door is described in detail below.

[0028] When the elevator system is idle (e.g., non-operating period), the car door is driven to enter the closing process. During the closing process, the floor door moves in the same direction driven by the car door. Usually, a driving mechanism such as a motor or a hydraulic system can be used to provide the force or driving force for driving the car door and the floor door. In addition to the driving force from the driving mechanism, the force applied to the floor door by the above-mentioned actuator also plays an auxiliary role in the closing of the floor door. When the combined force of the driving force and the auxiliary force is large enough, the resistance of the car door and the floor door (e.g., the friction between the car door and the floor door and the door frame) can be overcome and closed. With the movement of the car door and the floor door, the gap between the car door and the floor door will gradually decrease until they are completely closed or closed. Therefore, whether the automatic closing function of the floor door is normal can be determined based on the result of whether the floor door can be closed normally or completely closed (the result can be obtained, for example, by the door closing position signal).

[0029] In some embodiments, the magnitude of the driving force can be selected so that it corresponds to or is substantially equivalent to the resistance of the car door (hereinafter, the driving force corresponding to the resistance of the car door is referred to as the balanced driving force). When the car door is driven by the balanced driving force, the external force on the landing door is the resultant force of the auxiliary force applied by the actuator and the resistance of the landing door; in this case, if the automatic closing function of the landing door is normal, the landing door will eventually enter a fully closed or closed state, otherwise, the landing door will not be closed normally or enter a fully closed state, so whether the automatic closing function of the landing door is normal can be judged based on the above results. The "corresponding" and "substantially equivalent" mentioned here mean that the balanced driving force can take values ​​within a certain range near the resistance, as long as the deviation of the value relative to the resistance does not have a substantial impact on the inspection result of the automatic closing function of the landing door.

[0030] In some cases, the resistance experienced by the car door varies with its position. Figure 1A The relationship curve between the resistance of the car door and its position is shown by way of example. The horizontal axis in the figure represents the position L of the car door (for example, the distance between the edge of the car door and the door frame), and the vertical axis represents the resistance f of the car door. As can be seen from FIG1 , during the period when the car door moves from the zero point of the position coordinate (corresponding to the start of the closing process or the moment when the car door leaf is in a fully open state) to the position coordinate L1 (corresponding to the time when the self-locking mechanism of the car door starts to act), the resistance f remains basically stable; during the period when the car door moves from the position coordinate L1 to the position coordinate L2 (corresponding to the car door being in a fully closed state), the resistance f changes in a spike shape. Although the shape of the relationship curve (for example, the peak value f of the spike) is not uniform, the resistance f is not uniform. peak The position interval ΔL (the interval between the position coordinate L1 and the position coordinate L2, etc.) varies with the structure and working principle of the car door self-locking mechanism and the application environment of the elevator system, but the change pattern of the resistance is similar.

[0031] In some embodiments, a relationship curve R2 between the balanced driving force and the position of the car door can be determined by a relationship curve R1 between the resistance of the car door and its position, and then the balanced driving force can be adjusted according to the relationship curve R2 so that the balanced driving force applied at each car door position is basically equivalent to the resistance of the car door.

[0032] In some embodiments, only when the car door reaches the position where its self-locking mechanism starts to act (e.g., the position coordinate L1 in FIG. 1 ), the balancing driving force begins to be adjusted to follow the drastic change in resistance f. However, the drastic change in resistance f within the position interval ΔL makes it difficult or even impossible for the balancing driving force to follow the resistance. To this end, in some embodiments, the balancing driving force can be stepped up within the position interval ΔL. Exemplarily, the balancing driving force F(L) can be determined by the following formula:

[0033]

[0034] In the above formula, L is the position coordinate of the car door, F0 and k are constants greater than 0, where F0 can be, for example, the average value of the resistance f of the car door in the position interval of 0 to L1, and k can be, for example, based on the position change of the car door during the action of the self-locking mechanism (for example, the length of the position interval ΔL), the position change of the car door during the application of the balanced driving force (for example, L2), or the travel distance and the peak value f of the resistance f in the position interval ΔL. peak Sure. Figure 1B The relationship curve between the balanced driving force and the position of the car door is shown, where the horizontal axis represents the position of the car door L, and the vertical axis represents the balanced driving force F(L) applied to the car door. Figure 1B, the relationship curve R2 shown follows the variation pattern defined by equation (1).

[0035] For example, the value of k can be determined using the following formula:

[0036]

[0037] The number of fields where α in the above formula is greater than 0 can be determined through experiments.

[0038] Although the adjustment of the balancing driving force in the above manner does not precisely follow the change of the resistance f, the inventor of the present application has found through research that the above adjustment method has a negligible effect on the inspection result of the automatic closing function of the landing door. In addition, for a driving mechanism such as a motor, the step-by-step increase of the driving force greatly reduces the difficulty of implementation.

[0039] A variety of methods can be used to determine the relationship between the resistance of the car door and its position. For example, in some embodiments, the car door and the landing door can be mechanically decoupled (i.e., the landing door will not move under the influence of the car door), and the car door can be made to move at a constant speed by controlling the driving force applied by the driving mechanism to the car door, and the driving force output by the driving mechanism when the car door moves at a constant speed is measured, thereby calculating the resistance of the car door. Subsequently, a curve of the relationship between the resistance of the car door and the position of the car door can be generated based on the applied driving force and the corresponding position of the car door (e.g. Figure 1A The curve R1 shown in FIG. 1 is used to determine the relationship curve between the balanced driving force and the position of the car door (for example, Figure 1B In some other embodiments, the relationship curve between the balanced driving force and the position of the car door may be calibrated regularly or irregularly.

[0040] The position of the car door can be determined, for example, by arranging a pair of wireless signal transmitters and wireless signal receivers between the car door and the door frame and measuring the signal strength received by the latter. In addition, it is possible to determine whether the self-locking mechanism of the car door has started to act based on a variety of signals. These signals include, for example, but are not limited to, sensing signals of sensors for monitoring the movement of the self-locking mechanism, current flowing through the self-locking mechanism, and signals from the position feedback device of the self-locking mechanism. As for the judgment of whether the car door is in a fully closed state, it can be determined by using the door closing position signal of the elevator system.

[0041] It is generally recognized that, no matter what the reason for the abnormality of the automatic closing function, the door will not be able to be completely closed. However, even if the door can be completely closed, the possibility of the automatic closing function failing in a short period of time cannot be ruled out. In order to detect this potential failure risk, in some embodiments of the present application, not only the complete closing ability of the door is concerned, but also time is introduced as a dimension of investigation, that is, only when the door can enter the closed state within a preset period of time from the start of the output of the balanced driving force by the self-driving mechanism, the automatic closing function of the door is determined to be normal.

[0042] The above-mentioned preset time period can be determined according to the position and movement speed of the landing door when the balanced driving force is applied. In some embodiments, for example, when the automatic closing function of the landing door is confirmed to be normal, the car door and the landing door can be coupled (that is, the landing door is driven by the car door), and when the landing door reaches a certain position, the car door is driven by the balanced driving force and the movement speed of the landing door at this time (for example, using a speed sensor arranged on the landing door), the position (for example, the aforementioned method based on signal strength) and the time required for the landing door to be normally closed or completely closed from the beginning of applying the balanced driving force are measured. The above-mentioned measurement method can be applied to multiple positions of the landing door, so as to obtain the calibration relationship between the movement speed, position and the time required for the landing door to be completely closed from the beginning of applying the balanced driving force. The time length in the calibration relationship (hereinafter referred to as the calibration time length) can be used to set the preset time period. Specifically, when performing the automatic closing function check operation, the above-mentioned calibration relationship is used to determine the corresponding calibration time length as the preset time period by the measurement signal of the position and movement speed of the landing door when the balanced driving force starts to be applied.

[0043] Although the balancing driving force can be applied at various moments in the closing process of the car door (e.g., when the car door starts to move or at a certain moment after it starts to move), in some embodiments, applying the balancing driving force at the beginning of the floor door closing process is beneficial for simplifying the implementation of the automatic closing function inspection operation. In particular, the research of the inventors of the present application shows that when the moment of applying the balancing driving force is the beginning moment of the floor door closing process, the initial speed of the floor door is highly repeatable, and the time required for the floor door to reach the fully closed state is also highly consistent. Therefore, the preset time period can be determined without measuring the speed and position of the floor door.

[0044] The automatic closing function inspection operation described above is applicable not only to a single floor door, but also to multiple floor doors. For example, the automatic closing function of each floor door can be inspected in sequence according to the order in the list of floor doors to be maintained and the inspection results can be stored in accordance with the inspection method described above until all floor doors have completed the inspection operation. It should be noted that the order of performing the inspection can be various specified orders, such as the floor order including the floor doors from the 1st floor to the nth floor or the floor doors from the nth floor to the 1st floor, or the order obtained by randomly selecting from the floor doors of the 1st to nth floors. In addition, the above inspection method is also applicable to the situation where a floor contains multiple floor doors. In this case, a corresponding device identifier can be assigned to each floor door to distinguish the floor doors.

[0045] In some embodiments, the stored inspection results may be sent to the cloud (e.g., transmitted to a remote server via an IoT gateway) or a mobile terminal (e.g., transmitted to mobile terminals such as mobile phones, tablet computers, portable computers, and wearable devices via a Bluetooth channel or a mobile communication system).

[0046] Figure 2 The method described below can be implemented by various devices, such as but not limited to a control device in an elevator system (such as a door controller or an elevator controller) and a dedicated device for detecting the automatic closing function of a floor door, etc., which are collectively referred to as devices for detecting the function of an elevator system or detection devices.

[0047] Figure 2 The method shown starts at step 201. In this step, the detection device determines whether the elevator system is suitable for entering the automatic inspection mode at the current time. If it is suitable for entering the automatic inspection mode, the process proceeds to step 202, otherwise, the process continues to wait. Exemplarily, the maintenance of the elevator system is usually performed during non-operating hours, so the detection device may allow the elevator system to enter the automatic inspection mode only when the current time is outside the operating hours and there is no elevator call request.

[0048] In step 202, the detection device obtains a door queue Q for which the door automatic closing function check is to be performed, and the queue includes one or more door FDs. i, each floor door is associated with one of the multiple floors (for example, it is set on the associated floor). In some embodiments, the order of floors (for example, from the 1st floor to the nth floor or from the nth floor to the 1st floor) is used as the order of performing inspections on the floor doors. However, it should be pointed out that this is not necessary, and other inspection orders can be adopted according to the needs of the application scenario (for example, only performing inspections on the floor doors on even or odd floors, or performing inspections on the floor doors with high usage frequency). Exemplarily, the sequence number i is used to indicate the order in which the floor door automatic closing function inspection operation is performed.

[0049] Then, step 203 is entered, in which the detection device causes the car to stop at the i-th floor door FD in the floor door queue Q. i (When the detection starts, i=1) the associated floor, that is, the car is parked at this floor. Optionally, the detection device also causes the floor door and the car door to be in an open state, such as Figure 3A shown.

[0050] Next, in step 204, the detection device causes the driving mechanism (e.g., a motor) of the car door CD to start applying a balanced driving force to the car door (e.g., by supplying power to the driving mechanism), thereby starting the car door and the i-th landing door FD. i In actual operation, a driving force greater than the balanced driving force F0 can be applied in a short time interval (e.g., several hundred milliseconds) at the beginning of the closing process to make the car door drive the landing door to start moving, and then the balanced driving force F0 is used to drive the car door CD. Although the driving force applied in the initial time interval is not equal to the balanced driving force, since the interval is relatively short, it is reasonable to regard the balanced driving force as being applied at the beginning of the closing process. During the period when the balanced driving force F0 is applied to the car door CD, the landing door FD i The gap is decreasing, such as Figure 3B shown.

[0051] Then, step 205 is entered, and the detection device determines a reference value or a preset period for judging whether the automatic closing function is normal. As described above, the balancing driving force can be applied at various moments in the closing process of the car door. If the balancing driving force is applied at the beginning of the closing process, the preset period can be determined without measuring the speed and position of the landing door. On the other hand, if the balancing driving force is applied to the car door during the closing process, a predetermined calibration relationship can be used to determine the corresponding calibration duration as the preset period by the landing door position and movement speed measured when the balancing driving force starts to be applied.

[0052] In step 206, the detection device determines whether the car door has reached the position where its self-locking mechanism starts to act (e.g., the position coordinate L1 in FIG. 1), for example, based on one or more of the sensing signal of the sensor monitoring the movement of the self-locking mechanism, the current flowing through the self-locking mechanism, and the signal from the position feedback device of the self-locking mechanism. If it has reached, then go to step 207, otherwise continue to determine whether the car door has reached the position.

[0053] In step 207, the detection device starts to adjust the balancing driving force. The relevant adjustment method has been described above and will not be repeated here.

[0054] Figure 2 The process shown in the figure enters step 208 after step 207. In this step, the detection device detects the floor door FD based on the floor door FD. i Specifically, if the landing door FD is closed within a preset period of time after the balanced driving force is applied to the car door CD, i Can be closed normally (e.g. Figure 3C As shown), determine the floor door FD i The automatic closing function of the landing door is normal, otherwise, the FD i The automatic closing function of the elevator is abnormal. For example, the door closing position signal of the elevator system can be used to determine whether the landing door FD is in place. i Whether to shut down completely.

[0055] Then, step 209 is entered, and the detection device stores the information about the landing door FD. i Check results of the automatic shut-off function.

[0056] Then in step 210 , the detection device determines whether the automatic closing function check of all the floor doors in the queue Q has been completed. If all the floor doors in the queue Q have been traversed, the process proceeds to step 211 , otherwise, the process proceeds to step 212 .

[0057] In step 211 , the detection device sends the inspection results of the automatic closing function of each floor door stored in step 209 to the cloud or the mobile terminal.

[0058] In step 212, the detection device increments the door number (i=i+1) so that the operation object of the subsequent step is updated to the next door in the queue Q. After completing step 212, Figure 2 The method flow shown returns to step 203, so that the automatic closing function check operation of the landing doors in the queue Q is performed.

[0062] The memory 420 stores a computer program 440 executable by the processor 430. In addition, the memory 420 may also store data generated by the processor 430 when executing the computer program 440 and data received from an external device via the communication unit 410 (e.g., a door queue Q to be inspected for the automatic closing function and an inspection result of the terminal closing function, etc.).
