Description

Technical Field

[0001] The present invention belongs to the technical field of elevator group control, and relates to an elevator group control timeout processing system and method. Background Art

[0002] Since there are many people using the elevators in residential buildings nowadays, many decoration, takeaway and courier workers will block the doors for a long time for their own convenience during work, which will then affect the group control logic judgment. Since the group control system doesn't know that there are takeaway or courier workers blocking the doors for a long time during delivery, it will cause the group control logic to become "stupid". For example, the group control assigns an instruction to Elevator No. 1, and then Elevator No. 1 is occupied by the courier and blocked from serving, but the group control doesn't know, and it takes more than a certain time to consider this elevator as timed out and not in service. Moreover, the recovery is generally judged based on how long it takes to close the door, which will affect the use of other people. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a processing system for elevator group control timeout, which timely withdraws the timed-out elevator from the group control and improves the elevator dispatching efficiency of the elevator group control system.

[0004] The present invention also provides a processing method for elevator group control timeout.

[0005] The processing system for elevator group control timeout of the present invention is implemented by the following technical solutions:

[0006] A processing system for elevator group control timeout includes:

[0007] A multi-dimensional timeout perception module: used to analyze the reasons for elevator timeout from multiple dimensions and angles;

[0008] A dynamic timeout adjustment module: used to dynamically adjust the timeout time based on the scenario;

[0009] An elevator group control processing module: used to perform elevator group control based on the adjusted timeout time.

[0010] Preferably, the multi-dimensional timeout perception module is used to analyze and judge whether the reason for elevator timeout is normal use or abnormal occupation.

[0011] Further, the multi-dimensional timeout perception module includes:

[0012] A door area behavior detection unit: to monitor the door area occlusion duration and behavior pattern in real time through a light curtain, an infrared sensor and a camera;

[0013] A car state analysis unit: using the cameras and sensors in the elevator car to collect the image information and personnel activity data in the car in real time; through an image recognition algorithm, to identify whether there are people staying still in the car for a long time; using a weight sensor to monitor the change of the car load;

[0014] Intention judgment unit: Monitor the opening and closing status and duration of the elevator door. If the elevator door opening button or the external call direction button is pressed for a long time, resulting in the elevator door being in the open state and the light curtain not detecting an obstruction, or the light curtain detects a long-term obstruction but there is no personnel entry or exit action, or the car load does not change during the obstruction, or there is no floor registration during the obstruction, it is determined that the elevator is abnormally occupied.

[0015] Preferably, the dynamic timeout calculation module adjusts the timeout time T using formula (1) dyn :

[0016]

[0017] Where: T dyn is the dynamically adjusted timeout time; T open is the door opening duration; k is the adjustment coefficient, 0 < k < 1.

[0018] Preferably, the working process of the elevator group control processing module includes:

[0019] Prerequisites:

[0020] T hold : The set timeout threshold;

[0021] T dyn : The dynamically adjusted timeout time;

[0022] F: The floor where the door closing timeout occurs;

[0023] F1: The floor where the door closes normally;

[0024] T: The timeout service recovery time;

[0025] T1: The time when the door closing is effective and there is no internal call to start timing;

[0026] S31. When the elevator is in group control, the group control board judges that elevator No. 1 is opening the door and timing at a certain floor. When the time exceeds the set threshold T hold , the elevator issues a forced door closing signal;

[0027] S32. After the elevator issues a forced door closing signal, it closes the door slowly. When the elevator fails to close the door forcibly, it will send a busy signal to the group control board. After receiving the busy signal, the group control board removes this elevator No. 1 from the group control and records it as not serving due to timeout; the elevator records the floor where the door closing timeout occurs as F. The elevator needs to wait until another floor closes normally or waits for T seconds without an internal call after closing the door normally on this floor before sending an idle signal to the group control board, and the group control board restores elevator No. 1 to group control;

[0028] S33. When the No. 1 elevator runs to another floor and records the current floor as F1, after the door closing in-place signal is valid, it starts to judge whether to resume the timeout service. When the door closing in-place signal of the elevator is valid, it judges the in-car call signal of the elevator. When there is still an in-car call signal in the elevator and it does not resume, it waits until the next floor and continues to judge and execute the S31 logical judgment; when the elevator on the F1 floor can close the door normally, it sends an idle signal to the group control board, and the group control board continues to dispatch the No. 1 elevator.

[0029] A method for handling elevator group control timeout in the present invention is implemented by the following technical solution:

[0030] A method for handling elevator group control timeout includes:

[0031] S1. Analyze the elevator timeout reason in real time from multiple dimensions and angles;

[0032] S2. Dynamically adjust the timeout time based on the scenario;

[0033] S3. Perform elevator group control based on the adjusted timeout time.

[0034] Preferably, step S1 is used to analyze and judge whether the elevator timeout reason is normal use or abnormal occupation.

[0035] Further, step S1 includes:

[0036] S11. Real-time monitor the duration of door area occlusion and the behavior pattern through the light curtain, infrared sensor and camera;

[0037] S12. Utilize the camera and sensors in the elevator car to collect the image information and personnel activity data in the car in real time; through the image recognition algorithm, identify whether there are people staying still in the car for a long time; use the weight sensor to monitor the change of the car load;

[0038] S13. Monitor the opening and closing state and duration of the elevator door. If the elevator door open button or the external call direction button is pressed for a long time, resulting in the elevator door being in the open state and the light curtain not detecting an occlusion, or the light curtain detects a long occlusion but there is no personnel entering or leaving action, or there is no change in the car load during the occlusion, or there is no floor registration during the occlusion, it is determined that the elevator is abnormally occupied.

[0039] Preferably, step S2 adjusts the timeout time T using formula (1) dyn :

[0040]

[0041] where: T dyn is the dynamically adjusted timeout time; T open is the door opening duration; k is the adjustment coefficient, 0 < k < 1.

[0042] Preferably, step S3 comprises:

[0043] S31, when the elevator is in group control, the group control board determines that the No. 1 elevator is timing the door opening at a certain floor. When the time exceeds the set threshold, the elevator sends a forced door closing signal;

[0044] S32, when the elevator sends a forced door closing signal, it closes the door slowly. When the elevator fails to close the door by force, it will send a busy signal to the group control board. After receiving the busy signal, the group control board will exit the No. 1 elevator from the group control and record it as timeout and out of service. The elevator records the door closing timeout floor as F. The elevator needs to wait until another floor closes the door normally or wait for T seconds without internal call after closing the door normally on this floor before sending an idle signal to the group control board. The group control board will restore the group control of the No. 1 elevator.

[0045] S33, when elevator No. 1 runs to another floor and records the current floor as F1, after the door closing signal is valid, it starts to determine whether the timeout service is restored. When the elevator door closing signal is valid, it determines the elevator internal call signal. When the elevator still has an internal call signal that is not restored, it waits until the next floor to continue to determine and execute S31 logic judgment; when the elevator on the F1 floor can close the door normally, it sends an idle signal to the group control board, and the group control board continues to dispatch elevator No. 1.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. By real-time identification of human blocking behavior and dynamic adjustment of timeout logic, the problem of decreased group control efficiency caused by people blocking the door for a long time can be solved. Abnormal occupancy can be detected and handled in time to avoid invalid occupancy of elevators, thereby improving overall scheduling efficiency.

[0048] 2. Multimodal perception greatly improves the accuracy of abnormal occupancy identification and reduces the misjudgment rate of abnormal occupancy.

[0049] 3. Dynamically adjust the timeout period based on the scenario to improve the elevator dispatching efficiency of the elevator group control system.

[0050] 5. It can prevent passengers from pressing the door open or blocking the light curtain for a long time, which will hinder the operation of the elevator, improve the efficiency of the elevator, and facilitate the use of other passengers. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Figure 3 The following is a flowchart of the elevator group control processing module in one embodiment of the present invention.

[0054] Figure 4 Flow chart of elevator group control processing method in an embodiment of the present invention. Detailed implementation manners

[0055] The following provides preferred embodiments of the present invention in conjunction with the accompanying drawings, and details the technical solutions of the present invention.

[0056] In one embodiment, the elevator group control framework is as Figure 1 shown: Under group control, the external call instruction is transmitted by the elevator to the group control board, and then the group control board distributes the instruction to the main board.

[0057] Embodiment 1:

[0058] An elevator group control timeout processing system, comprising:

[0059] Multi-dimensional timeout perception module: used to analyze the reasons for elevator timeout from multiple dimensions and angles.

[0060] In one embodiment, the multi-dimensional timeout perception module is used to analyze and judge whether the reason for elevator timeout is normal use (for example, due to a large number of people entering and leaving during the peak work period) or abnormal occupation (for example, a courier blocking the door for loading and unloading goods). It includes:

[0061] Door area behavior detection unit: real-time monitors the duration of door area occlusion and behavior patterns through a light curtain, infrared sensors and cameras.

[0062] Car status analysis unit: uses cameras and sensors in the elevator car to collect image information and personnel activity data in the car in real time. Through image recognition algorithms, it identifies whether there are people in the car staying still for a long time. A weight sensor can also be used to monitor the change of the car load.

[0063] Intention judgment unit: monitors the opening and closing status and duration T open of the elevator door. If the elevator door open button or the external call direction button is pressed for a long time, resulting in the elevator door being in the open state and no occlusion is detected by the light curtain, or the light curtain detects a long-term occlusion but there is no personnel entering or leaving action, or there is no change in the car load during the occlusion, or there is no floor registration during the occlusion, it is determined that the elevator is abnormally occupied.

[0064] Dynamic timeout adjustment module, dynamically adjusts the timeout time based on the scenario.

[0065] In one embodiment, the dynamic timeout calculation module adjusts the timeout time T using formula (1) dyn .

[0066]

[0067] where: T dyn is the dynamically adjusted timeout time. T openis the door opening duration. After the door opens to the fully open position, the light curtain, touch panel, or door opening button starts timing. k is an adjustment factor, where 0 < k < 1. The adjustment factor is used to extend the elevator's door opening duration during normal usage scenarios (such as peak commuting hours).

[0068] Elevator group control processing module: Performs elevator group control based on the adjusted timeout.

[0069] In one embodiment, the working process of the elevator group control processing module is as Figure 3 shown, including:

[0070] Preconditions:

[0071] T hold : The set timeout threshold. For example: 45 seconds.

[0072] T dyn : The dynamically adjusted timeout.

[0073] F: The floor where the door closing timeout occurs.

[0074] F1: The floor where normal door closing occurs.

[0075] T: The timeout service recovery time.

[0076] T1: The time starts to be counted when the door closing is effective and there is no internal call.

[0077] S31. When performing elevator group control, the group control board determines that elevator No. 1 is opening the door and timing at a certain floor. When the time exceeds the set threshold T hold , the elevator will issue a forced door closing signal.

[0078] S32. After the elevator issues a forced door closing signal, it closes the door slowly. When the forced door closing fails, it will send a busy signal to the group control board. After receiving the busy signal, the group control board removes this elevator No. 1 from the group control and records it as not being serviced due to timeout. The elevator records the floor where the door closing timeout occurs as F. The elevator needs to wait until another floor closes normally or waits for T seconds without an internal call on this floor before sending an idle signal to the group control board, and the group control board resumes the group control of elevator No. 1.

[0079] As Figure 2 shown, when elevator No. 1 is out of the group control, the external call instruction of elevator No. 1 is transmitted by the elevator to the group control board without allocating elevator No. 1. After waiting for the idle signal to be sent and then reconnecting as before. Figure 1 Connected.

[0080] S33. When Elevator No. 1 runs to another floor and records the current floor as F1, after the door closing in-place signal is valid, start to judge whether the timeout service is restored. When the door closing in-place signal of the elevator is valid, judge the car call signal in the elevator. If there is still a car call signal in the elevator and it does not recover, wait until the next floor and continue to judge and execute the S31 logical judgment. When the elevator on the F1 floor can close the door normally, send an idle signal to the group control panel, and the group control panel continues to dispatch Elevator No. 1.

[0081] Note: Since the group control will remove this elevator from the group control after the elevator sends a busy signal, this elevator will not respond to external calls and will only respond to internal commands until an idle signal is sent to the group control. The group control reconnects the elevator to the group control, and the external commands in the group control state are controlled by the group control panel for dispatching.

[0082] The following explains the elevator group control timeout handling system of the present invention from two specific application scenarios:

[0083] Scenario 1: During the peak period in the mall, Elevator No. 1 has a long door opening time on the 3rd floor due to a large number of passengers getting on and off. The system dynamically adjusts T dyn from 45 seconds to 55 seconds. After the timeout, the door closes at 70% speed to avoid pinching passengers. If Elevator No. 1 continuously times out due to a door machine failure, the system automatically marks it as "abnormal" and schedules other elevators to give priority to responding to requests on the 3rd floor.

[0084] Scenario 2: The multi-dimensional timeout perception module recognizes that the courier blocks the door for loading and unloading goods, resulting in a long door opening time that exceeds the set threshold T hold At this time, the elevator will issue a forced door closing signal. When the forced door closing of the elevator fails, a busy signal will be sent to the group control panel. After receiving the busy signal, the group control panel removes Elevator No. 1 from the group control and schedules other elevators to serve passengers.

[0085] Embodiment 2:

[0086] An elevator group control timeout handling method, as Figure 4 shown, includes:

[0087] S1. Analyze the reasons for elevator timeout in real time from multiple dimensions and perspectives.

[0088] In one embodiment, step S1 is used to analyze and judge whether the reason for elevator timeout is normal use (for example, due to a large number of people getting on and off during the rush hour) or abnormal occupation (for example, the courier blocks the door for loading and unloading goods); it includes:

[0089] S11. Real-time monitor the duration of door area occlusion and behavior patterns through a light curtain, infrared sensor, and camera;

[0090] S12. Use the cameras and sensors inside the elevator car to collect the image information and personnel activity data inside the car in real time; through image recognition algorithms, identify whether there are people staying still for a long time inside the car; use weight sensors to monitor the load change of the car.

[0091] S13. Monitor the opening and closing status and duration of the elevator door. If the elevator door open button or the external call direction button is pressed for a long time, resulting in the elevator door being in the open state and the light curtain not detecting any obstruction, or the light curtain detecting an obstruction for a long time but no personnel entering or leaving action, or no change in the car load during the obstruction, or no floor registration during the obstruction, then it is determined that the elevator is abnormally occupied.

[0092] S2. Dynamically adjust the timeout based on the scenario.

[0093] In one embodiment, step S2 adjusts the timeout T using formula (1). dyn .

[0094]

[0095] Where: T dyn is the timeout after dynamic adjustment. T open is the door opening duration. After the door reaches the open position, the light curtain or touch panel or door open button is timed. k is the adjustment coefficient, 0 < k < 1. The adjustment coefficient is used to extend the elevator's continuous door opening time in normal usage scenarios (such as peak commuting hours).

[0096] S3. Perform elevator group control based on the adjusted timeout.

[0097] In one embodiment, step S3 includes:

[0098] S31. When performing elevator group control, the group control board determines that when the No. 1 elevator opens the door and times at a certain floor, and the time exceeds the set threshold T hold , the elevator will send a forced door closing signal.

[0099] S32. After the elevator sends a forced door closing signal, it closes the door slowly. When the elevator fails to close the door forcibly, it will send a busy signal to the group control board. After receiving the busy signal, the group control board removes this No. 1 elevator from the group control and records it as not serving due to timeout. The elevator records the floor where the door closing timeout occurs as F. The elevator needs to wait until another floor closes normally or waits for T seconds without an internal call on this floor before sending an idle signal to the group control board, and the group control board resumes the group control of the No. 1 elevator.

[0100] S33. When the No. 1 elevator runs to another floor and records the current floor as F1, after the door closing in-place signal is valid, it starts to judge whether the timeout service is restored. After the door closing in-place signal of the elevator is valid, it judges the in-car call signal of the elevator. When there is still an in-car call signal in the elevator and it does not recover, it waits until the next floor and continues to judge and execute the S31 logical judgment. After the elevator on the F1 floor can close the door normally, it sends an idle signal to the group control board, and the group control board continues to dispatch the No. 1 elevator.

[0101] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
