[0025] 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.

[0026] 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.

[0027] 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. During the closing process, the car door or floor door will gradually reduce the gap between the doors until it is normally closed. The normal closing 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 leaves (when the door includes multiple door leaves), and can also refer to the gap between the door leaf and the door frame (when the door includes only one door leaf).

[0028] In this specification, "automatic closing function of floor door" refers to the function of prompting the floor door to close, prohibiting the floor door from opening or locking the floor door when the elevator system is in a specific state (for example, the car is not on this floor and the floor door is completely closed). It should be pointed out that the implementation of the automatic closing function of the floor door depends on the coordinated operation of multiple levels and multiple components. For example, with respect to the floor door of the elevator system, the control device (such as the door controller or the elevator controller) will monitor the state 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 state signal of the floor door (such as the door closing position signal) to the control device; for another example, the actuator is a key component, which usually performs the action of closing, locking or unlocking the floor door based on the instruction of the control device. This means that the abnormal operation of any level or component may cause the abnormality of the automatic closing function of the floor door. For example, the aging of the spring or the loss of the counterweight will make the driving force no longer exist, the foreign matter in the door guide rail will hinder the movement of the door, and when the door wheel is adhered with oil, the friction will increase, all of which will cause the door to fail to close normally.

[0029] 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 landing door is in the closed state, the spring will apply a certain force to the landing door to drive the landing door into a fully closed state and keep the landing door closed. The gravity hammer (Counter weight) is another component in the actuator. The gravity hammer drives the landing door into a fully closed state and keeps the landing door locked by gravity. Usually, a separate gravity hammer or spring can be configured for each landing door.

[0030] During the closing process, the driving mechanism of the elevator system drives the car door and the landing door to move. 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 landing door. In addition to the driving force from the driving mechanism, the force applied to the landing door by the above-mentioned actuator (such as a spring device and a gravity hammer, etc.) also plays an auxiliary role in the closing of the landing door. When the combined force of the driving force and the auxiliary force is large enough, the resistance of the car door and the landing door (such as the friction between the car door and the landing door and the door frame) can be overcome and closed. When the car door and the landing door move as a whole, they have the following dynamic equation:

[0031] F 1 -f landing +F 2 -f car =ma (1)

[0032] In the above formula, it is assumed that the force is positive in the closing direction and negative in the opening direction, F 1 F is the force applied by the actuator on the landing door. 2 is the driving force exerted by the driving mechanism on the car door and landing door, f landing is the resistance encountered by the landing door during its movement (e.g. the friction between the landing door and the door frame), car is the resistance encountered by the car door during its movement (such as the friction between the car door and the door frame), m is the sum of the masses of the car door and the landing door, and a is the acceleration of the car door and the landing door as a whole.

[0033] The inventor of the present application has found through research that the net force F acting on the landing door is net (It is equal to F 1 -f landing ) and the automatic closing capability of the landing door (the automatic closing capability determines whether the landing door can be automatically closed or whether the automatic closing function is normal). In some embodiments of the present application, the net force on the landing door is used to measure the automatic closing capability. Further, the judgment can be made based on a single threshold, that is, the net force F net Compared with a preset value TH, when the former is greater than or equal to the latter, it is determined that the floor door can be closed normally, otherwise, it is determined that the floor door cannot be closed normally. The above preset value TH can be determined based on field experiments or simulation experiments. It should be pointed out that the research of the inventor of the present application shows that a single threshold is sufficient to make a good distinction between the normality of the automatic closing function and has a low false alarm rate and missed alarm rate for functional abnormal events. This is beneficial to the simplification of the judgment logic.

[0034] The automatic closing function detection method described above is not only applicable to a single floor door, but also to multiple floor doors. For example, the automatic closing function of each floor door can be detected in turn according to the order in the list of floor doors to be maintained and the detection method described above, until all the floor doors in the list have completed the detection operation. It should be noted that the order of performing the detection 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 it can be the order obtained by randomly selecting from the floor doors of the 1st to nth floors. In addition, the above detection 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.

[0035] In some embodiments, to determine the net force F net , the driving force of the driving mechanism can be controlled to make the car door and the landing door move in a uniform linear motion during the closing process. In the state of uniform linear motion, the above formula (1) can be rewritten as:

[0036] F net =F 1 -f landing =-F 2 +f car (2)

[0037] In the above formula (2), the driving force F of the driving mechanism on the car door and the landing door is 2 It can be determined based on the state variables of the driving mechanism. Taking the motor as an example, since the induced current and output torque of the motor have a corresponding relationship (e.g., a proportional relationship), the driving force F applied by the motor to the car door and the landing door can be obtained from the induced current as the state variable. 2 For another example, the output torque of the motor can also be used as a state variable.

[0038] In addition, the resistance f in the above formula (2) car For example, in some embodiments, the car door and the landing door can be separated from the mechanical coupling (that is, the landing door will not move under the drive of the car door), and the driving force F of the driving mechanism is 2 It only acts on the car door. By adjusting the driving force of the driving mechanism to make the car door move in a uniform linear motion, the resistance f on the car door can be determined. car (For example, the driving force applied by the driving mechanism under uniform linear motion can be determined as the resistance f car). It should be noted that the inventor of the present application has found through research that for the same car door, it remains essentially unchanged or changes very little at various movement speeds and at various positions of the car door, which makes it possible to ignore the influence of factors such as movement speed and position when determining the resistance, thereby determining the landing door resistance in an efficient and concise manner. In other embodiments, the resistance f may be measured regularly or irregularly in the manner described above. car Calibration is performed to reflect changes in car door performance (such as changes in friction caused by car door wear, etc.).

[0039] Various methods can be used to achieve uniform linear motion of the car door and the landing door by controlling the driving force applied by the driving mechanism to the car door and the landing door. Taking the driving mechanism as a motor as an example, it usually has a constant speed output mode, in which the induced current of the motor is adjusted based on a control algorithm such as PID to make the car door and the landing door move in a uniform linear motion. Generally, controlling the movement speed of the car door and the landing door at a lower level is beneficial to improving the accuracy of the judgment result of the automatic closing ability of the landing door. Exemplarily, the speed of the uniform linear motion of the landing door and the car door can be controlled in the range of 20 mm / second to 80 mm / second.

[0040] In some embodiments, the door controller and the elevator controller determine whether the floor door can be closed normally based on the driving force of the driving mechanism and the resistance encountered by the elevator door, and then send the judgment result to the cloud platform (for example, transmitted to a server cluster providing cloud computing services via an Internet of Things gateway) or a mobile terminal (for example, transmitted to mobile terminals such as mobile phones, tablets, portable computers and wearable devices via a wireless signal transceiver).

[0041] In some other embodiments, the judgment on the automatic closing capability of the landing door is performed at the cloud platform or the mobile terminal. At this time, the door controller or the elevator controller can actively send the state variables of the driving mechanism of the elevator system (such as the induced current or output torque of the motor, etc.) to the cloud platform or the mobile terminal regularly or irregularly, and can also provide the state variables to the cloud platform or the mobile terminal in response to the data access request of the cloud platform or the mobile terminal.

[0042] In some embodiments, only when the elevator system is in a specific working mode (such as a test mode), the state variables of the car door and the floor door when they are in uniform linear motion are obtained by controlling the drive mechanism. However, it should be noted that this is not the only way. In some other embodiments, the door controller or the elevator controller stores the state variables of the drive mechanism when the floor door and the car door are in various operating states; then, the state variables corresponding to the car door and the floor door when they are in uniform linear motion can be extracted from the stored state variables for judging the automatic closing ability of the floor door. Since it is no longer necessary to put the elevator system into a specific working mode in order to obtain the state variables in the uniform linear motion state, the workload of upgrading and modifying the existing elevator system can be minimized.

[0043] Figure 1 The method described below can be implemented by various devices, such as but not limited to control devices in the elevator system (such as door controllers or elevator controllers) and special devices for detecting the automatic closing function of the floor door, etc., and these control devices and special devices are collectively referred to as detection devices.

[0044] Figure 1 The method shown starts at step 101. In this step, the detection device determines whether the elevator system is suitable for entering the detection mode at the current time. If it is suitable for entering the detection mode, the process proceeds to step 102, 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 detection mode only when the current time is outside the operating hours and there is no elevator call request.

[0045] In step 102, 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.

[0046] Then, the process proceeds to step 103, in which the detection device obtains the i-th floor door FD in the car door and floor door queue Q. i (When detection starts, i=1) During the closing process, when the elevator system's driving mechanism makes uniform linear motion, the state variable VARi (such as the induced current of the motor), where the subscript i corresponds to the sequence number of the layer door in the queue Q.

[0047] then, Figure 1 The process shown enters step 104. In this step, the detection device determines whether the state variable VAR of the driving mechanism when all the doors in the queue Q are moving in a uniform linear motion has been obtained. 1 ~VAR n If all the layer doors in the queue Q are traversed, then go to step 105, otherwise, go to step 106.

[0048] In step 105, the detection device converts the state variable VAR obtained in step 104 when the doors of each floor move in a uniform linear motion into 1 ~VAR n Send to the cloud platform or mobile terminal. Optionally, obtain the movement speed V of the car door and the landing door when the state variable is obtained 1 ~V n Can be sent along with state variables.

[0049] In step 106, the detection device increments the floor door sequence number (i=i+1) so that the operation object of the subsequent step is updated to the next floor door in the queue Q. After completing step 106, Figure 1 The process shown returns to step 103, thereby executing the state variable acquisition operation on other layer doors in the queue Q.

[0050] In the right Figure 1 In a modification of the embodiment shown, in step 105, the detection device may detect the state variable VAR obtained in step 104 based on the state variable VAR 1 ~VAR n To determine whether the doors of each floor in the queue can be closed normally, and send the judgment result to the cloud platform or the mobile terminal. Exemplarily, the detection device can use the judgment logic based on a single threshold described above to obtain the judgment result.

[0051] Figure 2 Flowchart of a method for detecting the automatic closing function of a landing door according to some other embodiments of the present application. Figure 2 right Figure 1 The implementation of step 103 in is further described.

[0052] Figure 2 The process shown starts at step 201, which is followed by, for example, Figure 1 In step 201, the detection device causes the car to stop at the i-th floor door FD in the floor door queue Q. i(i=1 when detection starts) 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.

[0053] Next, in step 202, the detection device prompts the driving mechanism (such as a motor) to start the car door CD and the i-th landing door FD. i Apply driving force to start the closing process of the car door and the i-th floor door.

[0054] Then, step 203 is entered, under the control of the detection device (for example, controlled by the door controller) or coordination (for example, the door controller implements control based on the instruction of the elevator controller), by adjusting the driving mechanism to apply to the car door CD and the landing door FD i The driving force on the car door and the landing door makes a uniform linear motion, and is stored in the car door CD and the landing door FD. i The state variable VAR of the driving mechanism when in uniform linear motion i (For example, the induction current of the motor, etc.) The specific implementation method of making the car door and the landing door move in a uniform linear motion has been described above and will not be repeated here. It should be noted that the state variable VAR i It can contain a single sample value or multiple time points t 1 ~t m In the latter case, the state variables will be used to obtain the sampling value of the driving mechanism at the car door CD and the landing door FD. i The driving force F applied at multiple times during uniform linear motion i 2 (t 1 )~F i 2 (t m ), the average value of these driving forces can be used for the landing door FD i The judgment of the automatic closing capability of the layer door (the superscript i here corresponds to the sequence number of the layer door in the queue Q).

[0055] After completing step 203, Figure 2 The process shown will go, for example, to Figure 1 Step 104 in .

[0056] Figure 3 Flowchart of a method for detecting the automatic closing function of a landing door according to some other embodiments of the present application. Figure 3 The method of judging the automatic closing capability of the landing door based on the state variables is further described.

[0057] Figure 3 The process shown starts at step 301, which is followed by, for example, Figure 1After step 104 in step 301, the detection device uses the state variable VAR i Determine the car door CD and landing door FD i (When detection starts, i=1) The driving force applied by the driving mechanism during uniform linear motion. For example, when the driving mechanism is implemented by a motor, the corresponding relationship (e.g., proportional relationship) between the induced current and the output torque of the motor can be obtained by using the state variable VAR i The induced current is used to obtain the driving force F applied by the motor to the car door and landing door i 2 , where the superscript i corresponds to the sequence number of the layer door in the queue Q. As mentioned above, when the state variable VAR i When the sampling values ​​at multiple moments are included, the driving force F applied at multiple moments can be i 2 (t 1 )~F i 2 (t m ) is taken as the driving force F applied by the motor to the car door and landing door i 2 .

[0058] Then, the process proceeds to step 302, where the detection device determines the driving force F based on the driving force F determined in step 301. i 2 and the resistance f of the car door CD during its movement, which is calibrated by the experiment car To determine the landing door FD i The net force F i net , where the superscript i corresponds to the sequence number of the layer door in the queue Q. The specific determination method can be, for example, the above formula (2).

[0059] After step 302, Figure 3 The process shown enters step 303. In this step, the detection device determines the net force F i net Is it greater than or equal to the preset value TH? If it is greater than or equal to, the floor door FD i Assign the flag TRUE that can be closed normally, otherwise, the floor door FD i Assign the flag FALSE that cannot be closed normally. Optionally, a corresponding preset value TH can be set for each landing door i To reflect the differences in the automatic closing capability requirements of floor doors.

[0060] After executing step 303, Figure 3The process shown enters step 304. In this step, the detection device determines whether the determination operation has been performed on all the floor doors in the queue Q. If all the floor doors in the queue Q have been traversed, the process enters step 305, otherwise, the process enters step 306.

[0061] In step 305, the detection device detects the landing door FD 1 ~FDR n The judgment result of the automatic shutdown capability is sent to the cloud platform or mobile terminal.

[0062] In step 306, 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 306, Figure 3 The process shown returns to step 301, thereby performing state variable acquisition operations on other layer doors in the queue Q.

[0063] Figure 4 The following is a flow chart of a method for detecting the automatic closing function of a floor door according to some other embodiments of the present application. The method described below can be implemented on a cloud platform or a mobile terminal.

[0064] Figure 4 The method shown starts at step 401. In this step, the cloud platform or the mobile terminal obtains the state variables associated with each floor door in the floor door queue Q. In some embodiments, the state variables are the state variables of the driving mechanism when the car door and the floor door are in a uniform linear motion state (for example, by means of Figure 2 The state variable VAR obtained by the embodiment shown 1 ~VAR n In some other embodiments, the cloud platform or mobile terminal can extract the state variables corresponding to the uniform linear motion of the car door and the landing door from the state variable set of the driving mechanism provided by the elevator system in various motion states of the car door and the landing door (also recorded as VAR for convenience). 1 ~VAR n ).

[0065] Then proceed to step 402. In this step, the cloud platform or mobile terminal uses the state variable VAR i Determine the landing door FD i (When detection starts, i=1) The driving force applied by the driving mechanism during uniform linear motion. i Determine the driving force F applied by the motor to the car door and landing door i 2 The method has been described above and will not be repeated here.

[0066] then, Figure 4The process shown in FIG. 4 enters step 403. In this step, the cloud platform or the mobile terminal determines the driving force F based on step 402. i 2 and the resistance f of the car door CD during its movement, which is calibrated by the experiment car To determine the net force F on the landing door i net . Determine the net force F i net The specific method has been described above and will not be repeated here. car The information can be sent to the cloud platform or mobile terminal regularly or irregularly by the elevator system, or can be called by the cloud platform or mobile terminal by accessing the elevator system.

[0067] Then, step 404 is entered, and the cloud platform or the mobile terminal applies the net force F i net Compare with the preset value TH, if it is greater than or equal to, the landing door FD i Assign the flag TRUE that can be closed normally, otherwise, the floor door FD i Set the flag FALSE if the shutdown fails normally.

[0068] After executing step 404, Figure 4 The process shown enters step 405. In this step, the cloud platform or mobile terminal determines whether the judgment operation has been performed on all the floor doors in the queue Q. If all the floor doors in the queue Q are traversed, it enters step 406, otherwise, it enters step 407.

[0069] In step 406 , the cloud platform or the mobile terminal will generate a detection report on the automatic closing capability of each floor door in the queue Q.

[0070] In step 407, the cloud platform or mobile terminal increments the door sequence 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 407, Figure 4 The process shown returns to step 402, thereby performing state variable acquisition operations on other layer doors in the queue Q.

[0071] Figure 5 The present invention is a schematic block diagram of an apparatus for implementing automatic closing function detection of a landing door according to some other embodiments of the present application. Figure 5 The device shown may be one of a cloud platform, an elevator controller, a door controller and a mobile terminal.

[0072] like Figure 5As shown, the apparatus 50 comprises a communication unit 510 , one or more memories 520 (eg non-volatile memory such as flash memory, ROM, hard drive, magnetic disk, optical disk), one or more processors 530 and a computer program 540 .

[0073] The communication unit 510 serves as a communication interface and is configured to establish a communication connection between the apparatus 50 and an external device (eg, a driving mechanism of a car door, etc.) or a network (eg, the Internet and a wireless local area network, etc.).
