Description

Technical Field

[0001] This application relates to the field of elevator technology, and in particular to a two-way mutual rescue system and method for inclined elevators. Background Technology

[0002] Inclined elevators, as special transportation equipment with an inclined angle, are widely used in rail transit, scenic spots, and other fields where vertical barrier-free elevators cannot be installed. They serve a wide range of people, including able-bodied adults, the elderly, children, people with disabilities, and pregnant women. The rapid and safe rescue of trapped passengers after an escalator malfunction is directly related to passenger safety and travel experience. Regarding escalator malfunction rescue, existing technologies include CN217024905U, which discloses an inclined elevator car rescue device that requires manual handling and installation between the elevator car and the safety passage to guide trapped passengers to evacuate via the safety passage; and CN217296832U, which discloses a rescue device for two inclined elevators operating simultaneously, requiring rescuers to manually control another inclined elevator to move to the opposite position of the malfunctioning elevator before installing the rescue device to connect the two cars for passenger transfer.

[0003] However, rescue devices for inclined elevators rely on safety passages for evacuation. Furthermore, when large-span inclined elevators malfunction, the process of moving and installing the devices and evacuating personnel is time-consuming and arduous, and carries the risk of falls. When two inclined elevators operate simultaneously, the rescue devices require advance preparation, transportation, and installation. Manual control, maintenance, and operation result in low positioning accuracy, reliance on manual operation, low automation, and significant rescue difficulties and inefficiencies. Therefore, existing inclined elevator rescue technologies suffer from insufficient safety, low automation, and low efficiency. Summary of the Invention

[0027] In the description of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0028] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0029] like Figure 1 The inclined elevator two-way mutual rescue system shown includes: a faulty inclined elevator A, a rescue inclined elevator B, and a remote monitoring subsystem C. The faulty inclined elevator A is equipped with an inclined elevator control subsystem A1, a car personnel detection device A2, a car position maintenance subsystem A3, a car lateral telescopic docking subsystem A4, a car safety door and power unit A5, a voice broadcast and multimedia device A6, a five-way communication subsystem A7, and an uninterruptible power supply system A8. The rescue inclined elevator B is equipped with an inclined elevator control subsystem B1, a car personnel detection device B2, a car position maintenance subsystem B3, a car lateral telescopic docking subsystem B4, a car safety door and power unit B5, a voice broadcast and multimedia device B6, a five-way communication subsystem B7, and an uninterruptible power supply system B8.

[0030] When the inclined elevator control subsystem A1 of the faulty inclined elevator A detects its own malfunction and stops outside the service floor, it activates the car personnel detection device A2 to confirm the number of trapped people in the car, initiates a distress call through the five-way communication subsystem A7, triggers the uninterruptible power supply electronic system A8 to ensure power supply to all subsystems, controls the voice broadcast and multimedia device A6 to play reassuring voice messages, the car position maintenance subsystem A4 prepares to emit a positioning beam, and the car safety door and power unit A5 enter standby mode; A1 sends a distress signal containing its own position, running direction and number of trapped people to the remote monitoring subsystem C and the inclined elevator control subsystem B1 of the rescue inclined elevator B. After confirmation, the remote monitoring subsystem C issues a mutual rescue command. B1 receives the command, activates the car personnel detection device B2 to confirm its car is unoccupied, and the uninterruptible power supply electronic system B8 ensures power for the rescue. It also controls the voice broadcast and multimedia device B6 to play a reminder to stop normal service. Communication is maintained through the five-way communication subsystem B7, and the rescue elevator is driven towards A. During operation, based on the number of beams received from A3 by the car position maintenance subsystem B3, B1 controls the rescue elevator to decelerate step-by-step to achieve precise alignment with A. After alignment, A1 and B1 simultaneously control their respective car safety doors and power units A5 and B5 to open the safety doors. A6 and B6 simultaneously play reminders for orderly personnel transfer. Simultaneously, A1 and B1 coordinate to control the car lateral extension and retraction docking subsystems A4 and B4 to complete the car docking and locking. A7 and B7 continuously ensure five-way communication, and A8 and B8 provide stable power throughout the process. During personnel transfer, A2 and B2 monitor the number of people in the elevator car in real time and report back to A1 and B1. A1 and B1 then synchronize the personnel data to the remote monitoring subsystem C. Once the transfer is confirmed to be complete, A1 and B1 control A5 and B5 to close the safety doors. B1 drives the rescue elevator to the nearest service floor in the original direction of A's operation. After reaching the floor, B6 plays an arrival reminder. Finally, B1 controls the rescue elevator to resume normal operation. A1 remains in a fault state pending subsequent maintenance. Power supply to each subsystem is still continuously guaranteed by A8 and B8 as needed.

[0031] To address the technical problems of insufficient safety, low automation, and low efficiency in existing inclined elevator rescue technologies, this application provides a two-way mutual rescue method for inclined elevators. The method includes: when an inclined elevator malfunctions and stops outside a service floor, detecting whether there are trapped personnel inside the car; if so, sending a distress signal to a remote monitoring subsystem and an adjacent rescue inclined elevator; sending a mutual rescue command to both the malfunctioning and rescue inclined elevators via the remote monitoring subsystem; upon receiving the distress signal and mutual rescue command, the rescue inclined elevator responds to the floor instructions registered in its own car and stops normal service; after confirming that no one is inside its car, controlling the rescue inclined elevator to move towards the stopped position of the malfunctioning inclined elevator; and by obtaining the distance between the rescue and malfunctioning inclined elevators, controlling the rescue inclined elevator to gradually decelerate until the car of the rescue inclined elevator... The malfunctioning inclined elevator car is aligned; after stopping, the malfunctioning inclined elevator car is docked and locked with the rescue inclined elevator car, transferring the trapped personnel from the malfunctioning inclined elevator car to the rescue inclined elevator car; after confirming the personnel transfer is complete, both cars are reset; the rescue inclined elevator is moved to the nearest service floor in the original direction of the malfunctioning inclined elevator, and upon reaching the nearest service floor, all trapped personnel are guided to leave, restoring normal operation. Based on this, the risk of tipping over during manual rescue can be avoided through automated docking and locking, and the safety of stopping can be improved by using beam detection and graded deceleration. The complex steps of manual handling devices are eliminated through fully automated control, significantly improving rescue efficiency and automation level. At the same time, it is suitable for the needs of special groups such as wheelchair users, solving the technical problems of insufficient safety, low automation and efficiency of existing inclined elevator rescue technology.

[0032] Figure 2 This is a flowchart illustrating the bidirectional mutual rescue method for inclined elevators provided in an embodiment of this application, as shown below. Figure 2 As shown, the method includes:

[0033] S201. When the inclined elevator malfunctions and stops outside the service floor, check whether there are trapped personnel in the car. If there are trapped personnel, send a distress signal to the remote monitoring subsystem and the adjacent rescue inclined elevator.

[0034] The distress signal includes the stopping position of the malfunctioning inclined elevator car, its original direction of travel, and the number of people trapped inside the car.

[0035] In this embodiment, the passenger detection device for a malfunctioning inclined elevator includes an image acquisition sub-device and a facial recognition unit. The image acquisition sub-device acquires images inside the elevator car, and the facial recognition unit identifies the images inside the car to obtain passenger information. This passenger information is then transmitted to the inclined elevator control sub-system. After receiving the passenger information, the inclined elevator control sub-system controls the voice broadcast and multimedia device to play reassuring voice messages and activates the alarm button. Simultaneously, it sends a distress signal to the remote monitoring sub-system and the control sub-system of the rescue inclined elevator via serial communication. At the same time, it automatically connects to the five-way communication sub-system to maintain communication between the trapped passengers and the outside world.

[0036] As an example, a 30° inclined elevator in a scenic area malfunctioned and stopped in the middle of the shaft. Its passenger detection device (which includes a camera and integrates a facial recognition algorithm) detected two trapped people (including one wheelchair user). The inclined elevator control subsystem sent a distress signal containing the location, original upward direction, and number of people.

[0037] Based on the above steps, the rescue process can be quickly triggered, and the rescue signals can be transmitted simultaneously to comfort the trapped personnel and ensure the accuracy of communication and information in the early stages of the rescue.

[0038] S202. Send mutual rescue commands to the malfunctioning inclined elevator and the rescue inclined elevator through the remote monitoring subsystem.

[0039] In this embodiment, after receiving a distress signal, the remote monitoring subsystem checks the situation inside the malfunctioning inclined elevator car using the car personnel detection device, communicates with the trapped personnel through the five-way communication subsystem to confirm that there are no safety hazards and that the conditions for rescue are met; simultaneously issues a one-click mutual rescue command to the control subsystems of the malfunctioning inclined elevator and the rescue inclined elevator; after receiving the command, the inclined elevator control subsystem of the malfunctioning inclined elevator controls the multimedia device inside the car to play the rescue procedure animation and personnel evacuation precautions.

[0040] As an example, the staff in the monitoring room saw through the video that no one was injured and the environment was safe inside the malfunctioning elevator car. After confirming through a five-way call that the trapped person was in good physical condition, they immediately issued a mutual rescue order.

[0041] Based on the above steps, it can be ensured that rescue conditions are compliant, and trapped personnel can be informed of the rescue process in advance, reducing panic among them.

[0042] S203. After receiving a distress signal and mutual rescue command, the rescue inclined elevator responds to the floor instructions registered in its own car and stops normal service; after confirming that no one is in its own car, it controls the rescue inclined elevator to run to the stopped position of the malfunctioning inclined elevator.

[0043] In this embodiment, after receiving the distress signal and mutual rescue command, the inclined elevator control subsystem of the rescue inclined elevator immediately performs a command blocking operation, cancels the registered elevator call commands outside the hall, closes the new command receiving channel, and continues to respond to the registered floor commands inside its own car. After the response is completed, normal service is stopped, and the voice broadcast and multimedia device play the reminder voice "The elevator has stopped normal service, please all passengers leave the car". At the same time, the car personnel detection device confirms that there is no one in the car, controls the car door to close, and drives the car to the stopped position of the faulty inclined elevator at the first inspection speed.

[0044] It should be noted that the command blocking operation should prioritize the response of registered commands to avoid abandoning customers midway.

[0045] As an example, when the rescue elevator receives a command, there is a registered instruction to go to the 3rd floor inside the car. It first sends the passengers to the 3rd floor, and after confirming that there is no one in the car, it runs to the location of the faulty elevator at a first inspection speed of 0.3m / s.

[0046] Based on the above steps, irrelevant commands can be avoided from interfering with the rescue, ensuring that the rescue elevator operates without load and improving the safety and efficiency of the rescue.

[0047] S204. By obtaining the distance between the rescue inclined elevator and the malfunctioning inclined elevator, control the rescue inclined elevator to decelerate step by step until the car of the rescue inclined elevator is aligned with the car of the malfunctioning inclined elevator.

[0048] In this embodiment, the beam emitting unit of the rescue inclined elevator emits a beam, and the beam receiving unit of the faulty inclined elevator receives the number of beams in real time to obtain the elevator car distance. When the detected number of beams is 0, the rescue inclined elevator maintains the first maintenance docking speed. When the number of beams changes from 0 to non-zero, the rescue inclined elevator decelerates to the second maintenance docking speed. When the number of beams reaches 1 / 2 of the preset total, the rescue inclined elevator decelerates to the third maintenance docking speed. When the number of beams reaches 3 / 4 of the preset total, the rescue inclined elevator decelerates to the fourth maintenance docking speed. When the number of beams reaches the preset total minus 1, the rescue inclined elevator decelerates to the fifth maintenance docking speed. When the number of beams reaches the preset total, the rescue inclined elevator stops running and the car alignment is completed.

[0049] As an example, the preset total number of beams is 8. When the rescue elevator detects that the number of beams has increased from 0 to 1, it decelerates to the second inspection docking speed of 0.1 m / s. When it reaches 4, it decelerates to the third inspection docking speed of 0.05 m / s. When it reaches 6, it decelerates to the fourth inspection docking speed of 0.03 m / s. When it reaches 7, it moves slowly at 0.01 m / s. When it reaches 8, it stops, and the two cars are precisely aligned.

[0050] Based on the above steps, precise stopping of the car can be achieved through graded deceleration, ensuring docking safety.

[0051] S205. After stopping, the car of the malfunctioning inclined elevator is docked and locked with the car of the rescue inclined elevator, and the trapped personnel in the car of the malfunctioning inclined elevator are transferred to the car of the rescue inclined elevator.

[0052] The docking and locking mechanism relies on the car's lateral telescopic docking subsystem, which includes an electromagnetic pin coil, a drive motor, and a lateral guide rail limiting groove.

[0053] In this embodiment, the control subsystem of the rescue inclined elevator sends a synchronization signal to the control subsystem of the malfunctioning inclined elevator. After the two control subsystems synchronize, they respectively turn on the power supply of their respective electromagnetic pin coils, causing the pins to retract and release the car lock. Then, they control the drive motors at the bottom of their respective cars to run, driving the cars to move closer to each other along the transverse guide rail, so that the electromagnetic pins are inserted into the transverse guide rail limit grooves of the opposite car, completing the docking and locking. The control subsystems of the malfunctioning inclined elevator and the rescue inclined elevator respectively send door opening commands to their respective car safety doors and power units. The power units drive the safety sliding doors to open until the door opening signal is detected. At the same time, the voice broadcasts and multimedia devices of the two elevators simultaneously play the reminder voice "Please transfer the trapped personnel to the rescue inclined elevator in an orderly manner" to guide the trapped personnel to transfer through the sliding doors.

[0054] It should be noted that synchronization of the two control systems is a key prerequisite for avoiding docking deviations.

[0055] Based on the above steps, the two cars can be stably docked, preventing accidental movement of the cars during the docking process and ensuring the safety of personnel transfer.

[0056] S206. After confirming that the personnel transfer is complete, control both cars to return to their original positions.

[0057] The criteria for determining whether the transfer of personnel is complete are to check the number of people in the malfunctioning inclined elevator and the rescue inclined elevator respectively. When the number of people in the rescue inclined elevator is consistent with the number of trapped people in the distress signal, and there is no one in the malfunctioning inclined elevator, the transfer is confirmed to be complete.

[0058] In this embodiment, the passenger detection devices of the faulty inclined elevator and the rescue inclined elevator respectively acquire the number of people in the car and transmit the acquired data to their respective inclined elevator control subsystems. If the transfer completion standard is met, the two control subsystems communicate and confirm, then control the car safety door and power unit to close the sliding door. After the sliding door is closed, the two control subsystems connect the power supply to the electromagnetic pin coil at the bottom of the car to unlock it, control the car bottom drive motor to drive the car to move away from each other, and after resetting, stop the motor, disconnect the electromagnetic pin power supply, and allow the car pin to insert into its own bottom limit groove to complete the reset and locking.

[0059] As an example, the camera detected two people in the rescue elevator (matching the number in the distress signal) and no one in the malfunctioning elevator. The two control subsystems automatically confirmed the transfer was complete and executed the door closing and reset operations.

[0060] Based on the above steps, the safe transfer of personnel can be ensured, omissions can be avoided, and the car can be safely reset.

[0061] As another example of S205-S207, such as Figure 3 The diagram showing the tilting elevator car displacement and reset illustrates that before docking, the car safety sliding doors 21 and 11 are closed. The faulty car's lateral telescopic drive motor 221, drive screw 222, and moving guide rail 223, along with the rescue car's 121, 122, and 123, are all in an initial standby state. During S205 car docking, once both elevator control subsystems are synchronized, the two cars approach and dock: the faulty tilting elevator's control subsystem drives its lateral telescopic drive motor 221, which, through the drive screw 222, moves car 2 along the lateral telescopic moving guide rail 223 (along axis 22) towards the rescue car 1; simultaneously, the rescue tilting elevator's control subsystem's drive motor 121, through the screw 122, moves car 1 along guide rail 123 (along axis 12) towards the faulty car 2, until the two cars are precisely docked and locked. At this point, the car safety sliding doors 21 and 11... 11 Alignment; If the faulty car cannot move actively, a single car approaches for docking: Only the control subsystem of the rescue inclined elevator drives motor 121, which drives car 1 to move along guide rail 123 toward the faulty car 2, completing docking and locking; When executing S206 for personnel transfer, the safety sliding doors 21 and 11 of the two cars open simultaneously, guiding the trapped personnel in the faulty car 2 to transfer to the rescue car 1; When executing S207 for reset, the two cars move away from each other: After confirming that the personnel transfer is complete, the horizontal telescopic drive motors 221 and 121 on the faulty side and the rescue side rotate in opposite directions, driving their respective cars along guide rails 223 and 123 in a direction away from each other (in the opposite direction along axis 22 and 12) through screws 222 and 122, and finally the two cars return to their initial positions along the horizontal guide rails, that is, reset in place. At this time, the car safety sliding doors 21 and 11 close, the horizontal telescopic subsystem returns to its initial state, and the car is locked.

[0062] S207. Control the rescue inclined elevator to move to the nearest service floor in the original direction of the malfunctioning inclined elevator. After reaching the nearest service floor, guide all trapped personnel to leave and restore normal operation.

[0063] In this embodiment, the rescue inclined elevator moves the car at the second inspection speed to the nearest service floor in the original direction of the malfunctioning inclined elevator. Upon arrival at the floor, the control subsystem controls the car door to open, and the voice broadcast device plays a reminder to "passengers please leave the elevator in an orderly manner." After the car personnel detection device confirms that all trapped personnel have left, the inclined elevator control subsystem deactivates the rescue mode, resumes receiving elevator calls from outside the hall and floor commands from inside the car, and the rescue elevator resumes normal operation.

[0064] As an example, the malfunctioning elevator was originally running upwards, while the rescue elevator moved at 0.1 m / s to the nearest 5th floor service floor. After arriving, it released the trapped people, wheelchairs, and luggage, and then resumed normal passenger service.

[0065] Based on the above steps, trapped personnel and wheelchairs can be safely transported to the service floor, while the normal service of the rescue elevator can be quickly restored, reducing the impact on elevator operation.

[0066] Based on the above technical solution, it is possible to avoid the risk of falling from the safety passage and the risk of overturning due to manual positioning by remotely issuing mutual rescue commands, automatically stopping and docking, and locking the car. At the same time, it eliminates the complicated process of manually carrying and installing rescue devices to improve rescue efficiency. It can also ensure that the rescue process is not interrupted by uninterrupted power supply, effectively solving the technical problems of insufficient safety, low automation and low efficiency of existing inclined elevator rescue technology.

[0067] The above primarily describes the solutions of the embodiments of this application from the perspective of device implementation. It is understood that each device, such as a two-way mutual rescue device for inclined elevators, includes at least one of the hardware structures and software modules corresponding to the execution of each function in order to achieve the above-mentioned functions. Those skilled in the art should readily recognize that, in conjunction with the units and algorithm steps of the various examples described in the embodiments disclosed herein, this application can be implemented in hardware or a combination of hardware and computer software.

The inclined elevator two-way mutual rescue device 40 includes a processing unit 401 and a communication unit 402, and may also include a storage unit 403.

[0071] For example, communication unit 402 is used for the remote monitoring subsystem to communicate with the inclined elevator control subsystem and to receive or transmit information;

[0072] Processing unit 401 is used to detect whether there are trapped personnel in the car when the inclined elevator malfunctions and stops outside the service floor. If there are trapped personnel, it sends a distress signal to the remote monitoring subsystem and the adjacent rescue inclined elevator. The distress signal includes the stopping position of the malfunctioning inclined elevator car, the original direction of travel, and the number of trapped personnel in the car. It also sends a mutual rescue command to the malfunctioning inclined elevator and the rescue inclined elevator through the remote monitoring subsystem. After receiving the distress signal and the mutual rescue command, the rescue inclined elevator responds to the floor instructions registered in its own car and stops normal service. After confirming that there is no one in its own car, it controls the rescue inclined elevator to return to the malfunctioning inclined elevator. The system operates from the stopped position of the malfunctioning inclined elevator; by obtaining the distance between the rescue inclined elevator and the malfunctioning inclined elevator, it controls the rescue inclined elevator to decelerate step by step until the cars of the rescue inclined elevator and the malfunctioning inclined elevator are aligned; after stopping, it controls the cars of the malfunctioning inclined elevator to dock and lock with the cars of the rescue inclined elevator, transferring the trapped personnel in the car of the malfunctioning inclined elevator to the car of the rescue inclined elevator; after confirming that the personnel have been transferred, it controls the two cars to reset; it controls the rescue inclined elevator to move to the nearest service floor in the original direction of travel of the malfunctioning inclined elevator, and after reaching the nearest service floor, it guides all trapped personnel to leave and resumes normal operation.
