Description

Technical Field

[0001] This application relates to the field of elevator technology, and in particular to an entry control method and related equipment for the top of an elevator car. Background Technology

[0002] The car top is the most important work area in elevator engineering operations, and the safety and efficiency of operating on the car top are very important.

[0003] Currently, when elevator maintenance personnel enter the elevator car top, it is usually done by professionals who, based on experience, determine the elevator's position while it is running. The maintenance personnel then use a triangular key to open the elevator hall door, triggering the elevator to stop before entering the car top. Once the car reaches the destination floor and is leveled, the maintenance personnel control the elevator to descend for inspection, then open the landing door to bring the elevator to an emergency stop before entering the car top. However, this existing method of entering the car top, because it is operated from the machine room or outside the hall, cannot precisely control the elevator's stopping position. When the position is too low or too high, there are safety risks for maintenance personnel entering the car top. Repeatedly adjusting the car position until the car top is level takes a considerable amount of time. Summary of the Invention

[0004] This application provides an elevator car top entry control method and related equipment to reduce the number of elevator movements and the time required to enter the car top.

[0005] The first aspect of this application provides an entry control method for the top of an elevator car, applied to an elevator main control system, including:

[0006] In response to the triggering of the car top entry switch inside the elevator car, the elevator enters the preparatory mode upon entering the car top.

[0007] Determine whether the current floor height of the elevator is greater than the preset height parameter between the car top and the sill.

[0008] If the current floor height of the elevator is greater than the preset height parameter, then in response to the pressing signal of the call button outside the elevator hall, the elevator door is controlled to close and enter the car top to enter the running mode.

[0009] The elevator is controlled to run towards the target location at a first operating speed, and when it is a first preset distance away from the target location, it switches to a second operating speed until it reaches the target location and then stops running; wherein the second operating speed is less than the first operating speed.

[0010] A second aspect of this application provides an elevator car top entry control system, applied to an elevator main control system, comprising:

[0012] The judgment unit is used to determine whether the current floor height of the elevator is greater than the preset height parameter between the car top and the sill.

[0013] The control unit is used to control the elevator to close the doors and enter the car top to enter the running mode when the current floor height of the elevator is greater than the preset height parameter, in response to the pressing signal of the call button outside the elevator hall.

[0014] The control unit is further configured to control the elevator to run towards the target location at a first running speed, and switch to a second running speed when it is a first preset distance away from the target location, until the elevator stops running after reaching the target location; wherein the second running speed is less than the first running speed.

[0021] A fifth aspect of this application provides a computer program product, the computer program product including instructions that, when executed on a computer, cause the computer to perform the elevator car top entry control method described in the first aspect.

[0022] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: The elevator car top entry control method disclosed in this application allows the elevator to enter car top entry mode by toggling the car top entry switch inside the elevator car. In this mode, the elevator can first run at a first running speed and then at a second running speed to the target position.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] To address the safety risks associated with maintenance personnel entering the elevator car top and the issues of repeatedly adjusting the car top position, this application discloses an entry control method for the elevator car top, which can be found in the following embodiments. Figure 1 , Figure 1 This is a flowchart illustrating an elevator car top access control method disclosed in an embodiment of this application. It includes steps 101-104.

[0033] 101. In response to the triggering of the car top entry switch inside the elevator car, enter the car top and enter the preparation mode.

[0034] Elevators typically have a maintenance mode and a normal mode in their factory settings. This application adds a car top entry mode, which disables both internal and external call functions. Additionally, in this embodiment, a toggle switch (i.e., a car top entry switch) is installed inside the elevator car.

[0035] In one specific embodiment, under normal elevator operation, if maintenance personnel reach the area outside the car top lobby of the desired floor, they can use the external call signal in the elevator lobby to summon the elevator to their floor. The maintenance personnel then enter the elevator car, open the elevator control panel using the key switch, and close the car top entry switch. At this point, the elevator main control system triggers the relevant detection functions of the car top entry switch, thus entering the car top entry preparation mode. The elevator remains open.

[0036] In some embodiments, when the elevator main control system enters the car top preparation mode, the system will control the car top buzzer to emit an audible and visual alert (i.e., the fourth audible and visual alert described above) to notify maintenance personnel that the elevator has entered the car top entry mode. It should be noted that the car top preparation mode described above is the initial stage of the car top entry mode, and for ease of understanding, it will not be elaborated upon further. The car top buzzer can sound continuously (e.g., 5s~10s). In this embodiment, it can be set to 5s to remind maintenance personnel.

[0037] In other feasible technical solutions, when the elevator main control system detects that the signal for the car top entry mode has a rising edge and is valid, it can enter the car top entry mode.

[0038] 102. Determine whether the current floor height of the elevator is greater than the preset height parameter between the car top and the sill.

[0039] Therefore, the elevator control system needs to detect the comparison between the current floor height and the preset height parameter. It should be noted that the preset height parameter is the height difference between the top of the elevator car and the floor sill. It should also be noted that the sill height typically refers to the vertical distance between the upper plane of the elevator sill and the upper plane of the floor sill after the elevator car has precisely leveled at a floor (i.e., the car floor and the floor floor are basically flush).

[0040] In some embodiments, the preset height parameter can be set by the elevator main control system, that is, adjusted according to the actual height of the elevator car top and sill. Specifically, the preset height parameter is not limited here, and will be represented by H thereafter.

[0041] Furthermore, in this embodiment, the main focus is on comparing whether the current floor height of the elevator meets the requirement of being greater than the preset height parameter H.

[0042] 103. If the current floor height of the elevator is greater than the preset height parameter, the elevator will respond to the call button outside the elevator hall by closing the elevator door and entering the car top to enter the running mode.

[0043] Based on the judgment result of step 102, if the current floor height of the elevator is greater than the preset height parameter, then in response to the pressing signal of the call button outside the elevator hall, the elevator door is controlled to close and enter the car top to enter the running mode.

[0044] In one specific embodiment, if the floor height of the current floor where the elevator is located is greater than the preset height parameter H, maintenance personnel can press the up or down call buttons outside the elevator hall, thereby activating the elevator main control system to enter the car top operation mode. It should be noted that the car top operation mode is only one stage of the car top entry mode, following the car top preparatory mode. For ease of understanding, this will not be elaborated upon further.

[0045] In some embodiments, the elevator doors will only close when maintenance personnel press the call button outside the elevator hall. After the doors close, the elevator main control system enters the car top operating mode. At this time, the elevator main control system will disable external call buttons outside the elevator hall, and the display screen outside the elevator hall will show the distance between the elevator car top on the current floor and the target location.

[0046] In other feasible technical solutions, the above-mentioned preset distance parameters can also be displayed on the display screen outside the elevator hall. Specifically, there are no restrictions on the content displayed on the display screen.

[0047] In other feasible technical solutions, based on the judgment result of step 102, if the current floor height of the elevator is less than a preset height parameter, the buzzer on the elevator car roof will emit an audible and visual warning (i.e., the first audible and visual warning mentioned above) to alert maintenance personnel that the current elevator car roof height does not meet the elevator car entry conditions. The buzzer on the car roof can sound continuously (e.g., 5s~10s). In this embodiment, it can be set to 5s to remind maintenance personnel.

[0048] 104. Control the elevator to run towards the target location at the first running speed, and switch to the second running speed when it is a first preset distance away from the target location, until the elevator stops running after reaching the target location.

[0049] After entering the car top and entering the operating mode, the elevator main control system will control the elevator to move towards the target position at a first operating speed. Then, when it is a first preset distance away from the target position, it will control the elevator to run at a second operating speed that is less than the first operating speed, until the elevator reaches the target position, and then control the elevator to stop.

[0050] In some embodiments, the elevator first descends at the maintenance running speed (first running speed), and when it is 0.2m away from the target distance (first preset distance), it switches to a speed of 0.1m / s (second running speed), and stops after reaching the target distance of 0.0m.

[0051] In some embodiments, when the elevator reaches the target location, the elevator main control system can also control the buzzer on the car top to emit an audible and visual alert (i.e., the fifth audible and visual alert mentioned above), and control the indicator light of the call button for the elevator floor corresponding to the target location to flash. The buzzer on the car top can sound continuously (e.g., 5s~10s). In this embodiment, it can be set to 10s to remind maintenance personnel that the elevator has arrived.

[0052] The elevator car top entry control method disclosed in this embodiment allows the elevator to enter car top entry mode by toggling a car top entry switch inside the elevator car. In this mode, the elevator first runs at a first operating speed and then runs at a second operating speed to the target position. This method eliminates the need for multiple people to coordinate operations inside or outside the car, effectively saving manpower and eliminating the need for maintenance personnel to repeatedly adjust the elevator position, thus increasing efficiency.

[0053] After entering the car roof entry mode, parameter calibration and position fine-tuning are still required. Please refer to [link / reference]. Figure 2 , Figure 2 This is a flowchart illustrating another elevator car top access control method disclosed in an embodiment of this application. It includes steps 201-205.

[0054] 201. When the pressing duration of the up or down button outside the elevator hall reaches the first preset duration, the height parameter adjustment mode is entered.

[0055] Based on the above description, it can be seen that after the elevator reaches the designated position, the button lights of the call buttons (including the up button or down button) on the floor corresponding to that designated position will flash continuously to remind maintenance personnel to complete the car top maintenance operation.

[0056] In one specific embodiment, when elevator maintenance personnel observe a deviation between the actual elevator car top position and the set height (preset height parameter), the maintenance personnel can press the up or down button outside the elevator hall for a first preset duration to modify the preset height parameter.

[0057] In some embodiments, for example, if the actual position where the elevator stops is 30cm higher than the sill, the elevator maintenance personnel can enter the height parameter adjustment mode of the elevator height by continuously pressing the down button outside the elevator hall for 5 seconds (as an example of the first preset time).

[0058] Alternatively, if the actual position of the elevator is 30cm below the sill height, elevator maintenance personnel can enter the height parameter adjustment mode by continuously pressing the up button outside the elevator hall for 5 seconds (for example, the first preset duration).

[0059] 202. The initial distance value of the current adjustment distance is displayed on the display panel outside the elevator hall.

[0060] After entering the height parameter adjustment mode, the elevator display panel on the floor where the elevator is located will display the initial distance value of the current adjustment distance.

[0061] In some embodiments, the elevator floor display panel will show elevator 00cm.

[0062] 203. In response to pressing the up or down button, adjust the initial distance value with a preset adjustment step value, and display the current adjustment direction and the cumulative adjustment distance value on the display panel.

[0063] Furthermore, in response to maintenance personnel pressing the up or down button, the elevator main control system will adjust the initial distance value according to the preset adjustment step value, and display the current adjustment direction of the elevator and the cumulative adjustment distance value after pressing the button in real time on the display panel.

[0064] In one specific embodiment, in conjunction with the embodiment of step 201, for example, pressing the up button adjusts the elevator by 2cm (the adjustment distance for one press can be set according to actual conditions), and the corresponding display content is an upward arrow ↑ and 02cm. Furthermore, when the display reaches the ↑ arrow at 30cm (corresponding to the preset height parameter), pressing the button can be stopped.

[0065] Alternatively, for example, pressing the down button adjusts the elevator height by 2cm (the adjustment distance per press can be set according to actual needs), with the corresponding display showing a down arrow (↓) and 02cm. Furthermore, pressing the button can be stopped when the down arrow reaches 30cm (corresponding to the preset height parameter).

[0066] 204. In response to the simultaneous pressing of the up button and the down button, the accumulated adjustment distance value and the adjustment height parameter calculated from the preset height parameter are saved to the elevator main control system.

[0067] Furthermore, in response to maintenance personnel simultaneously pressing the up and down buttons, the new adjustment height parameter calculated from the current actual adjustment distance and the previously preset height parameter can be saved to the elevator main control system.

[0068] In one specific embodiment, pressing the elevator's up and down buttons simultaneously associates the accumulated adjustment distance value (current actual adjustment distance H0) with the previously set preset height parameter H, calculates a new adjustment height parameter value, and saves it to the elevator's main control system.

[0069] In some embodiments, pressing the elevator's up and down buttons simultaneously allows the current adjustment distance H0 and the previously preset height parameter H to be used as new parameter values. Saved to the elevator's main control system.

[0070] 205. Control the elevator to run at the third operating speed. When the current running distance of the elevator reaches the accumulated adjustment distance value, control the elevator to stop running and control the buzzer on the car top to emit a second audible and visual warning.

[0071] When the elevator main control system detects the aforementioned height parameter modification and the elevator meets the relevant operating conditions, the system can control the elevator to run at the third operating speed. Then, the adjusted distance value H0 modified in step 204 is used as the initial distance for this elevator adjustment. Furthermore, the current operating direction of the elevator is determined based on the relationship between the adjusted height parameter and the preset height parameter. When the adjusted height parameter is greater than the preset height parameter, the elevator descends; when the adjusted height parameter is less than the preset height parameter, the elevator ascends. Therefore, when the elevator's operating distance reaches the adjusted distance value H0, the elevator main control system can control the elevator to stop. Simultaneously, the buzzer on the car top will continuously sound for 5-10 seconds (i.e., the second audible and visual prompt mentioned above. In this embodiment, it can be set to 10 seconds) to alert maintenance personnel that the elevator's location has been reached.

[0072] In one specific embodiment, after detecting the aforementioned height parameter modification, and once the elevator meets the operating conditions, the elevator operates at a speed of 0.05 m / s (one implementation of the third operating speed), using the modified distance parameter H0 as the initial distance. When the new parameter value... When the new parameter value is greater than H, the elevator descends. When the distance is less than H, the elevator goes up. When the travel distance reaches H0, the elevator stops. After the elevator reaches the position, the buzzer on the car top sounds continuously for 10 seconds to indicate that maintenance personnel have arrived. The button lights of the elevator call buttons for up and down on this floor flash to indicate that maintenance personnel have completed the car top maintenance operation.

[0073] The elevator car top entry control method disclosed in this embodiment eliminates the need for two people to cooperate inside and outside the car, allowing one person to independently complete the boarding operation, thus saving manpower. It also eliminates the need for repeated manual adjustments to the elevator position; only the height parameters need to be modified according to the actual elevator stopping position to complete the elevator height adjustment, resulting in higher safety and efficiency. Furthermore, the entire process, from mode entry and parameter adjustment to saving and execution, can be completed simply by operating the common up / down buttons outside the elevator hall, significantly reducing the operational threshold and complexity. The entire adjustment process is displayed in real-time on the display panel, showing the adjustment direction and cumulative distance, providing clear operational feedback for maintenance personnel. After adjustment, the elevator automatically performs low-speed fine leveling, confirmed by audible and visual prompts, effectively ensuring the safety of maintenance work. Moreover, preset step values ​​are used for fine-tuning, avoiding errors from experience-based estimations and making the leveling height adjustment more precise. The high degree of automation significantly improves maintenance efficiency.

[0074] After the elevator reaches the designated location, the process of switching modes and exiting modes also needs to be implemented. Please refer to [link / reference]. Figure 3 , Figure 3 This is a flowchart illustrating another elevator car top access control method disclosed in an embodiment of this application. It includes steps 301-305.

[0075] 301. Start the timer.

[0076] After the car top maintenance operation is completed, the elevator main control system will start a timer. Then, depending on whether a trigger signal from the car top inspection switch is detected, step 302 or step 303 will be executed.

[0077] In some embodiments, the elevator remains in a stopped state while the elevator main control system starts a timer.

[0078] 302. If no trigger signal is detected from the car top maintenance switch when the timer expires, exit the car top and enter the running mode.

[0079] Furthermore, the timer will monitor the trigger signal of the car top maintenance switch in real time (such as the rising edge indicator light of the car top maintenance switch). If no trigger signal of the car top maintenance switch is detected when the timer expires, the car top mode will be exited and the car will enter the running mode.

[0080] In some embodiments, the timer can be set to 5 minutes. Then, when the elevator main control system does not detect the signal input of the car top inspection switch at the 5th minute (or the maintenance personnel have not entered the car top for more than 5 minutes and have not turned on the inspection switch), it will exit the car top entry mode, and the elevator will return to the normal operation mode.

[0081] 303. If a trigger signal of the car top maintenance switch is detected before the timer expires, the elevator main control system is controlled to switch from the car top operating mode to the car top maintenance mode.

[0082] Furthermore, the timer monitors the trigger signal of the car top inspection switch in real time (e.g., the rising edge indicator light of the car top inspection switch). If the elevator main control system detects the trigger signal of the car top inspection switch before the timer expires, it enters the car top inspection mode.

[0083] In some embodiments, the timer can be set to 5 minutes. Then, when the elevator main control system detects a signal input from the car top inspection switch at the 5th minute (or when maintenance personnel enter the car top and turn on the inspection switch within 5 minutes), the elevator main control system will enter inspection mode, that is, the elevator main control system will switch from car top entry mode to car top inspection mode. At this time, maintenance personnel can enter the car top to perform elevator maintenance work.

[0084] 304. In response to the trigger signal of the elevator main control system exiting the car top inspection mode, control the elevator to run to the level position, and control the car top buzzer to emit a third audible and visual prompt to remind maintenance personnel to operate.

[0085] After maintenance personnel complete the elevator inspection, they can operate the inspection switch, which will trigger the elevator main control system to exit the car top inspection mode (or a falling edge signal, etc.). Subsequently, after the elevator main control system detects the exit from the car top inspection mode, the elevator will automatically return to the floor level and move to the leveling zone (the leveling zone refers to the vertical space within which the elevator car can ensure normal door opening and safe passenger entry and exit when it stops at a floor). At this time, the car top buzzer will continuously sound (i.e., the third audible and visual warning mentioned above), for example, 5 to 10 seconds. In this embodiment, it can be set to 10 seconds to remind maintenance personnel to enter the elevator car and restore the car top entry switch to normal mode.

[0086] 305. In response to the detection that the car top entry switch has returned to an invalid state, control the elevator main control system to exit the car top entry operation mode so that the elevator can return to normal operation.

[0087] Therefore, after maintenance personnel enter the elevator car top and restore the car top access switch to normal mode, the elevator main control system will check the switch's status. If the switch is invalid, the elevator main control system will exit the car top inspection mode and the car top access mode (the car top access switch is invalid), thus restoring the elevator to normal operation.

[0088] In some embodiments, the external call display panel in the elevator lobby will be activated, allowing passengers to call the elevator normally.

[0089] This embodiment discloses an elevator car top entry control method that automatically manages the switching of maintenance modes through dual judgment of time and signal, eliminating safety hazards caused by human negligence (such as forgetting to exit maintenance mode). Simultaneously, when exiting maintenance mode, the system automatically performs a leveling operation and activates a buzzer to proactively remind and guide maintenance personnel to safely evacuate the car top, greatly improving operational safety. The entire process requires no additional manual intervention for resetting; the system automatically resumes normal operation after confirming safety, reducing elevator standby time and improving maintenance efficiency.

[0090] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
