Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically to an elevator system with rescue function. Background Technology

[0002] Elevators are a common facility in daily life, and safety is paramount. However, existing elevators frequently malfunction, with doors often failing to open or close properly, leading to entrapment. The most common cause of these malfunctions is the inability to open or close doors correctly. In practice, there are many reasons for this, requiring a comprehensive assessment of the elevator's performance parameters to determine if a fault exists and initiate rescue operations. Currently, most elevator systems rely on passengers discovering malfunctions inside the elevator, such as malfunctions, accidental stops, or failure to stop at the selected floor, resulting in entrapment. In such cases, passengers must manually press the alarm button to contact control room personnel for assistance. The lack of proactive fault diagnosis and alarm alerts delays rescue efforts and increases the likelihood of accidents. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides an elevator system with rescue capabilities, solving the problem that current elevator systems cannot effectively and automatically detect faults and proactively issue alarms for rescue.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: an elevator system with rescue function, comprising a monitoring module for monitoring the elevator interior, including a fault detection module, a fault early warning module, a remote control module, and an energy management module interconnected with each other, wherein...

[0007] The fault detection module is used to monitor the elevator's operating status in real time. It includes a sensor network installed inside the elevator, which collects the elevator's operating data, including the elevator's position, speed, current, and voltage. The module analyzes the operating data to determine whether the elevator has a fault that prevents it from starting.

[0008] The fault warning module is used to immediately activate the warning program after receiving the signal from the fault detection module. The warning program includes at least one of the following forms: sound, light, and mobile APP, to issue an alarm to passengers and maintenance personnel.

[0009] The remote control module allows managers and elevator maintenance personnel to remotely control the elevator. The remote control operations include restarting or forcibly stopping the elevator when it is inaccessible via a mobile app or computer software.

[0010] The energy management module supplies power to the monitoring facilities and control components of the elevator, monitors the elevator's power consumption in real time, and immediately sends a buzzer alarm to the management personnel when power consumption is abnormal, in order to prepare for rescue.

[0011] Preferredly, the monitoring modules are installed in the four corners and the center of the elevator car. The cameras in the four corners are bullet cameras, and the camera in the center is a PTZ camera.

[0012] Prioritizes the operation data, which includes the current and voltage of the frequency converter, PLC, input / output modules, and the real-time position of the car.

[0013] Prior to this, the real-time position includes the height position of the car. When the car is detected to be at a set height H, if the value of H is not within the range of N*h*(±k%), where N is a natural number, h is the floor height, and k<30, then the car door is not allowed to be opened. If it is opened, the fault detection module records it as a fault occurrence and immediately sends a signal to the fault warning module, so that the fault warning module immediately issues an alarm.

[0014] Prior to this, distance sensors are installed on the opposite sides of the two elevator doors. The two distance sensors are used to detect the distance between each other. When the car door is closed, the data detected by the two distance sensors is a minimum value, which means that the car door has been completely closed. If the real-time value detected by the distance sensor is not the minimum value, the fault warning module will immediately issue an alarm.

[0015] Preferably, a blind hole is provided on the opposite sides of the car door, and the distance sensor is installed in the blind hole. The distance sensor is coaxially arranged with the blind hole and is completely located within the blind hole.

[0016] Furthermore, the fault detection module also includes a door lock status monitoring module. The data information monitored by the distance sensor is sent to the door lock status monitoring module, and the door lock status monitoring module also includes a door limit monitor for monitoring the opening and closing status of the car door.

[0017] Furthermore, the door limit monitor is installed in the sliding direction of the car door panel and is at least partially located within the interlayer of the door panel. It includes a seat tube and a pressure sensor, a pressure spring, a sliding column, and a contact block fixed to the inner side of the door panel.

[0018] The seat tube is horizontally installed on one side inside the door panel. One end of the seat tube is open and the other end is closed. The pressure sensor is fixed inside the closed end. One end of the pressure spring is in contact with the pressure sensor, and the other end is used to slide axially with the sliding column and is inserted into the open end of the seat tube without being fixedly connected. The end of the sliding column protruding from the seat tube is fixedly connected to the contact block. When the two door panels are close together and completely closed, the sliding column and the pressure spring are not in contact, and the pressure value of the pressure sensor is 0. When the two door panels are opened and move away from each other, the pressure sensor increases due to the compression of the pressure spring. When it increases to a set threshold, it indicates that the car door has been completely opened.

[0019] When the pressure value detected by the pressure sensor exceeds the threshold, or when the distance between the two distance sensors is smaller than the minimum value, the fault detection module sends a signal to the fault warning module, causing the fault pre-tightening module to alarm.

[0020] Furthermore, when the fault detection module sends a signal to the fault warning module, causing the warning signal to be sent by the fault warning module, it also communicates with the remote control module, causing the remote control module to immediately drive a pre-drive mechanism of the car door.

[0021] When the pressure value detected by the fault detection module exceeds the threshold, the pre-transmission mechanism drives the corresponding door panel to slide in the closing direction, and stops sliding when the detected pressure value is equal to the threshold.

[0022] When the distance value detected by the fault detection module between the two distance sensors is smaller than the minimum value, the pre-drive mechanism drives the corresponding door panel to slide in the direction of opening the door, and stops sliding when the detected distance value is equal to the minimum value.

[0023] Preferably, the backup transmission mechanism includes a backup motor, a drive gear, a driven rack, and a belt drive assembly. The drive gear and the driven rack are both located inside the door panel. The drive gear is rotatably installed in the interlayer inside the door panel, while the driven gear is horizontally fixed in the interlayer. The main shaft of the backup motor is connected to the drive gear via the belt drive assembly. The drive gear meshes with the driven rack, and the driven rack is arranged parallel to the seat tube.

[0024] (III) Beneficial Effects

[0025] This invention provides an elevator system with rescue function, which, in short, has the following main advantages:

[0026] 1. This invention is based on existing intelligent communication technology and integrates multiple modules to monitor elevators in real time and provide alarms and rescue. It can send out distress signals without the need for personnel to actively press the alarm button, making it safe and reliable.

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

[0032] As one embodiment illustrating the detailed concept of the present invention, an elevator system with rescue function is described. The main structure includes not only a monitoring module for monitoring the elevator interior, but also interconnected fault detection, fault warning, remote control, and energy management modules. Specifically, the fault detection module in this embodiment is mainly used to monitor the elevator's operating status in real time. This includes a sensor network installed inside the elevator, which collects the elevator's operating data. This operating data specifically includes the elevator's position, speed, current, and voltage. The system analyzes the operating data to determine if the elevator has a fault preventing it from opening. These data are set according to the specific elevator model and can be referenced to the specific rated operating parameters.

[0033] Meanwhile, the fault warning module in this embodiment is used to immediately activate the warning program and issue an alarm upon receiving the signal from the fault detection module, thereby achieving a notification function. Specifically, this warning program includes at least one of the following methods: sound, light, and a mobile app, to issue an alarm to passengers and maintenance personnel. Given the current prevalence of information communication and smart terminals, it is recommended that all three be linked together. For example, the mobile app could directly issue an alarm and flash an indicator light, since mobile phones are now an essential item for everyone.

[0034] Furthermore, the remote control module in this embodiment is primarily used by managers and elevator maintenance personnel to remotely control the elevator. It can also be equipped with users when necessary. As one of the specific implementation details, this remote control operation includes using a mobile app or computer software, allowing for quick restarting or forced shutdown of the elevator when it is inaccessible, avoiding delays caused by manual on-site arrival. As for the energy management module, it supplies power to the monitoring facilities and elevator control components, and can monitor the elevator's power consumption in real time. When power consumption is abnormal, it immediately sends a buzzer alarm to the management personnel to request assistance, thus providing strong protection for the safe operation of the elevator.

[0035] In its specific design, this monitoring module is installed in the four corners and the center of the elevator car. The cameras in the four corners are fixed bullet cameras, providing a consistent field of view and preventing vibrations that could disrupt the view. This is because cameras with adjustable angles are typically manually adjustable, meaning the lens could shake in unexpected situations. Therefore, fixed bullet cameras are recommended for the corners. The camera in the center is a PTZ camera, providing a clear and comprehensive view of the center and surrounding area. With five cameras working together, there are no blind spots, allowing for real-time monitoring of people inside the elevator. Furthermore, existing AI recognition technology can detect whether there are passengers in the car, enabling staff in the central control room to take timely and appropriate action.

[0036] In this embodiment, the operational data includes the current and voltage of the frequency converter, PLC, and input / output modules, as well as the real-time position of the elevator car. Specifically, the control system is the core of the elevator, mainly comprising the frequency converter, PLC, and input / output modules. Testing of the control system primarily focuses on frequency converter testing, specifically checking for short circuits, open circuits, and other abnormalities, and verifying the normality of operating parameters such as current and voltage. Similarly, PLC testing requires checking for short circuits, open circuits, and verifying the normality of operating parameters such as input / output status and clock. As for the testing of the corresponding input / output terminals of the controller, it mainly involves monitoring the normality of the input / output signals.

[0037] More specifically, the real-time position in this embodiment includes the height position of the car. That is, when the car is detected to be at a set height H, if the value of H is not within the range of N*h*(±k%), where N is a natural number, h is the floor height, and k < 30, it indicates that the car is likely not located in the lobby area of ​​a certain floor. The ±k% range is to mitigate the possibility of false alarms caused by slight swaying or falling during the elevator door's movement due to installation errors in the lobby and door, as well as the car's internal load. When the car is outside the aforementioned range, the door is not allowed to open, otherwise an accident could easily occur. If the elevator door opens at this time, the fault detection module records it as a fault and immediately sends a signal to the fault warning module, causing the fault warning module to immediately issue an alarm to alert the current management personnel and passengers.

[0038] Regarding the opening and closing control of elevator doors, it can be as follows: Figure 1 Distance sensors 9 are installed on the opposite sides of the two elevator doors. Each distance sensor 9 detects its own distance from the other. When the elevator doors are closed, the data detected by the two distance sensors 9 is a minimum value, for example, 3 cm. This minimum value indicates that the elevator doors are completely closed. If the real-time value detected by the distance sensors 9 is not a minimum value, for example, 10 cm, it means that there is still a gap of approximately 7 cm between the door panels 1, and the elevator doors are not completely closed. The fault warning module will immediately issue an alarm. (Continue reading...) Figure 1 In this embodiment, a blind hole is provided on the opposite sides of the car door. A distance sensor 9 is installed in the blind hole. The distance sensor 9 is coaxially arranged with the blind hole and is completely located inside the blind hole to achieve a minimum value greater than 0.

[0039] In practice, the fault detection module also includes a door lock status monitoring module. Data monitored by the distance sensor 9 is sent to the door lock status monitoring module, and the door lock status monitoring module also includes a door limit monitor to monitor the opening and closing status of the car door. Figure 1-2As shown, the door limiter mentioned in this embodiment can be installed in the sliding direction of the door panel 1 of the car door and at least partially located in the interlayer of the door panel 1. It includes a seat tube 3 and a pressure sensor 4, a pressure spring 5, a sliding column 6 located in the seat tube 3, and a contact block 8 fixed to the inner side of the door panel 1. A detailed structural description is as follows: The seat tube 3 is horizontally installed on one side inside the door panel 1 and fixed inside the car wall 2. The seat tube 3 and the door panel 1 are slidably fitted together. Specifically, one end of the seat tube 3 is open and the other end is closed. A pressure sensor 4 is fixed inside the closed end. One end of the pressure spring 5 is in contact with the pressure sensor 4, and the other end is used to slide axially into the open end of the seat tube 3 without being fixedly connected. The end of the slide column 6 protruding from the seat tube 3 is fixedly connected to the contact block 8. When the two door panels 1 are close together and completely closed, the slide column 6 and the pressure spring 5 are not in contact, and the pressure value of the pressure sensor 4 is 0. When the two door panels 1 are opened away from each other, the pressure sensor 4 increases due to the compression of the pressure spring 5. When it increases to a set threshold, it indicates that the car door has been completely opened. Using the change in pressure value to characterize whether the door panel 1 is completely closed is more sensitive than sensing the distance and also plays a double insurance role. In the above structural design, the reason for installing the seat tube 3 and the contact block 8 in the interlayer inside the door panel 1 is to greatly reduce the structural size of the elevator, make full use of the structural characteristics of the elevator door panel 1 for modification, and improve practicality. If the seat tube 3 is directly installed outside one side of the door panel 1, the footprint of the entire elevator will be greatly increased.

[0040] In the above implementation details, when the pressure value detected by pressure sensor 4 exceeds the threshold, it indicates that door panel 1 is still operating incorrectly after being fully opened, which may cause damage to door panel 1 and the corresponding transmission system. Alternatively, if the distance value between the two distance sensors 9 is smaller than the minimum value, it indicates that the two door panels 1 may have come into contact with each other and been squeezed, causing deformation and damage to door panel 1, etc. Therefore, in the above situations, it is necessary to send a signal to the fault warning module through the fault detection module to trigger the fault pre-tensioning module to alarm. At the same time, the fault detection module also communicates with the remote control module, so that the remote control module immediately drives a pre-drive mechanism 7 of the car door to perform transmission. The specific operating mechanism is as follows: when the pressure value detected by the fault detection module exceeds the threshold, the pre-drive mechanism 7 drives the corresponding door panel 1 to slide in the closing direction, and stops sliding when the detected pressure value equals the threshold to ensure safety. When the distance value detected by the fault detection module between the two distance sensors 9 is smaller than the minimum value, the pre-drive mechanism 7 drives the corresponding door panel 1 to slide in the opening direction, and stops sliding immediately when the detected distance value equals the minimum value.

[0041] In addition, the system in this embodiment is also equipped with a separate, independently used pre-transmission mechanism 7, such as... Figure 1 As shown, it mainly includes a backup motor, a drive gear 702, a driven rack 701, and a belt drive assembly 703. Both the drive gear 702 and the driven rack 701 are located inside the door panel 1, for the same reason as the aforementioned door limiter being installed in the interlayer of the door panel 1. Specifically, the drive gear 702 is rotatably installed in the interlayer within the door panel 1, while the driven gear is horizontally fixed in the interlayer. The main shaft of the backup motor is connected to the drive gear 702 via the belt drive assembly 703. The drive gear 702 meshes with the driven rack 701, which is arranged parallel to the seat tube 3. Thus, when needed, the backup motor can be directly started to drive the door panel 1 to open or close, immediately rescuing people trapped inside the elevator.
