Description

Technical Field

[0001] This invention relates to the field of elevator safety technology, and more specifically to a high-precision elevator safety monitoring device capable of detecting the status of personnel. Background Technology

[0002] With the development of the real estate industry, the development and usage of elevators have reached new heights. However, at the same time, elevators are becoming increasingly intertwined with people's lives, leading to a rise in safety issues and higher demands for elevator safety performance. Currently, elevator safety protection primarily relies on safety brakes, buffers, and speed governors, but these measures generally have a certain degree of lag. Once these components activate, it means a safety incident has already occurred, resulting in a poor riding experience for passengers and even personal injury. In special elevator applications such as schools, hospitals, nursing homes, and high-end hotels, there are even higher requirements for elevator safety, including real-time performance, accuracy, and ease of use. Based on these needs, multi-dimensional and intelligent elevator safety detection systems have emerged, such as…

[0003] Authorized announcement number CN110436299A provides an elevator safety monitoring device, relating to the field of elevator safety, including: a traction motor, a mounting base, a levelness detection component, a slippage detection component, a control module, and an elevator alarm module; the traction motor includes: a housing and a traction sheave, the mounting base is mounted on the housing, the mounting base includes: a base plate and a vertical plate, the vertical plate is perpendicular to the base plate and located on the side of the base plate away from the housing; the levelness detection component is disposed between the bottom of the traction sheave and the upper surface of the base plate, the slippage detection component is disposed between the outer side of the traction sheave and the vertical plate, the control module is electrically connected to the levelness detection component and the slippage detection component, and controls the elevator alarm module to start and stop according to the detection results. This invention can effectively monitor whether the traction sheave is level and whether it has a slippage tendency, making it safer, structurally stable, and relatively simple to install and manufacture.

[0004] However, existing safety monitoring devices mainly focus on safety protection outside the car, lacking real-time monitoring of the status of people inside the car. As a result, the safety monitoring devices only activate after a safety incident occurs, making it impossible to prevent incidents in advance, and the safety protection effect of the devices is too delayed.

[0005] Therefore, in order to address the above problems, there is an urgent need for innovative design based on the existing clamping device. Summary of the Invention

[0006] The purpose of this invention is to provide a high-precision elevator safety monitoring device capable of detecting the status of personnel, in order to solve the problem mentioned in the background art that current safety monitoring devices mainly focus on the safety protection outside the car, lacking real-time monitoring of the status of personnel inside the car, resulting in the safety monitoring device only activating after a safety incident occurs, failing to prevent it in advance, and causing the safety protection effect of the device to be too delayed.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-precision safety monitoring device for elevators capable of detecting the status of personnel, comprising: a body connecting seat, and a preset hole opened on the outer side of the body connecting seat, wherein the lower end of the preset hole is connected to a body shell, and an installation shell is provided inside the body shell;

[0008] Also includes:

[0009] A first drive motor is installed in the middle of the body connecting seat, and a guide plate is provided on the lower side of the first drive motor. A guide ring is installed on the upper side of the body shell, and a movable battery is provided on the upper left side of the body shell. A second drive motor is installed on the rear side of the body shell, and a drive mounting plate is connected to the front end of the second drive motor. An anti-deviation guide block is provided on the outer side of the drive mounting plate, and an elastic fixing component is provided on the outer side of the mounting shell.

[0010] A data connection cable is installed on the left side of the mounting housing, and an intelligent controller is located in the middle of the mounting housing. An infrared sensor is installed on the right side of the mounting housing, and a laser sensor is installed above the infrared sensor. An image recognition module is located behind the laser sensor, and a protective plate is installed to the right of the image recognition module. A smoke sensor is located on the upper side of the protective plate.

[0011] In one possible scenario, the guide ring is rotatably connected to the body connecting seat, and the longitudinal section of the guide ring has an "L" shaped structure.

[0012] In one possible implementation, the anti-deviation guide block is set at an equal angle on the outside of the drive mounting plate, and both the anti-deviation guide block and the drive mounting plate are rotatably connected to the outer casing of the machine body.

[0013] In one possible implementation, the mounting housing is rotatably connected to the body housing and slidably connected to the drive mounting plate.

[0014] In one possible scenario, the protective plate is engaged with the mounting housing.

[0015] In one possible scenario, the guide plate is rotatably connected to the outer casing.

[0016] In one possible implementation, the elastic fastening assembly includes a return spring mounted on the outside of the mounting housing, and a limit block is connected to the outside of the return spring. The lower end of the limit block is provided with an operating rod, and a guide plate passes through the middle of the operating rod.

[0017] The limiting block is engaged with the drive mounting plate, and the limiting block is symmetrically arranged about the central axis of the mounting housing.

[0018] In one possible implementation, the guide plate is slidably connected to the operating lever, and the longitudinal section of the guide plate is an "I" shaped structure.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects: This high-precision elevator safety monitoring device, capable of detecting the status of personnel, monitors the status of personnel inside the elevator car in real time by directly installing high-precision sensor modules in the elevator car. This allows the safety monitoring device to effectively assess risks based on sensor data before a safety incident occurs, enabling preventative operations to be performed before an accident occurs, thus enhancing the safety protection effect of the device. At the same time, the collaborative work of high-precision sensors and components such as image recognition modules allows for specific analysis of the actual situation in the elevator car, thereby improving the accuracy and reliability of the device's detection, reducing false alarms and missed alarms, and ensuring the device's accuracy in responding to different situations. This reduces the possibility of accidents during safe elevator use and has a better performance, as detailed below.

[0020] 1. The return spring, in conjunction with the guide plate, pushes the limit block and the operating lever to move outward, so that the outwardly displaced limit block locks the mounting housing and the drive mounting plate. At this time, the data connection line on the left side of the mounting housing is connected in series with the machine housing. By adopting this quick-release structure design, the operator can effectively replace and repair the mounting housing when the sensor module on the right side of the mounting housing is damaged. It is also convenient for maintenance personnel to quickly disassemble the mounting housing when climbing to a high place, avoiding the risk of falling due to prolonged exposure to heights, and improving the maintenance efficiency of the device.

[0021] 2. The first drive motor, in conjunction with the guide plate, pushes the outer casing of the machine body to rotate horizontally along the guide ring at the lower end of the machine body connecting seat. At the same time, the second drive motor, in conjunction with the drive mounting plate and the anti-deviation guide block, pushes the mounting casing to rotate clockwise inside the outer casing of the machine body. This causes the mounting casing to move the infrared sensor, laser sensor, and image recognition module installed on its right side downwards. This allows the operator to adapt and adjust the position of the infrared sensor, laser sensor, and image recognition module according to the usage requirements of the device. It also allows the device to calibrate the support position of the infrared sensor, laser sensor, and image recognition module according to the space conditions of different elevator cars, ensuring that the monitoring effect of the device is not affected and improving the versatility of the device.

[0022] 3. By combining smoke sensors with infrared sensors, laser sensors, and image recognition modules, the elevator car interior is monitored in real time using infrared, laser, and smoke detection combined with image acquisition. This allows the intelligent controller to process and analyze the input data through its built-in algorithms, thereby determining the passengers' status and performing a detailed analysis of the actual situation in the elevator car. This improves the accuracy and reliability of the device's detection, reduces false alarms and missed alarms, and ensures accurate response to different situations, thus reducing the possibility of safety issues during elevator use.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Please see Figures 1-7 The present invention provides the following technical solution:

[0034] A high-precision safety monitoring device for elevators capable of detecting personnel status includes: a body connecting seat 1, a preset hole 2, a first drive motor 3, a guide plate 4, a body shell 5, a guide ring 6, a movable battery 7, a battery cover 8, a second drive motor 9, a drive mounting plate 10, an anti-deviation guide block 11, a mounting shell 12, a reset spring 13, a limit block 14, an operating pull rod 15, a guide plate 16, a data connection cable 17, an intelligent controller 18, an infrared sensor 19, a laser sensor 20, an image recognition module 21, a protection board 22, and a smoke sensor 23.

[0035] Specifically, such as Figure 1 , Figure 4 and Figure 5As shown, before using the device, by pulling the operating lever 15 inward, the operating lever 15 causes the limiting block 14 connected to its upper side to move inward and compress the return spring 13. Due to the sliding connection structure between the guide plate 16 and the operating lever 15, the inwardly moving operating lever 15 is guided and limited by the guide plate 16, preventing the limiting block 14 and the operating lever 15 from shifting positions during movement. At this time, because of the sliding connection structure between the mounting housing 12 and the drive mounting plate 10, the operator can easily install the mounting housing 12 along the drive mounting plate 10 set inside the housing 5. When the pulling of the operating lever 15 is released, the compressed return spring 13 loses the limitation of the pulling force and generates a rebound reaction force. At this time, the return spring 13 pushes the outer connecting... The reset spring 13 re-displaces outward along the operating lever 15 and guide plate 16. Due to the engaging connection between the limiting block 14 and the drive mounting plate 10, the outwardly displaced limiting block 14 locks the mounting housing 12 and the drive mounting plate 10 together, thus completing the quick installation of the mounting housing 12. At this time, the data connection line 17 on the left side of the mounting housing 12 is connected in series with the body housing 5. By adopting this quick-release structure design, when the operator finds that the sensor module on the right side of the mounting housing 12 is damaged, the mounting housing 12 can be effectively replaced and repaired. It is convenient for maintenance personnel to quickly disassemble the mounting housing 12 when climbing to a high place, avoiding the possibility of falling due to prolonged exposure to high altitudes, and improving the maintenance efficiency of the device.

[0036] Specifically, such as Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, after completing the assembly of the mounting housing 12 and the body housing 5, the body connecting seat 1 is placed at one corner of the top of the elevator car. The screw is then passed through the pre-drilled hole 2, and the screw is rotated. This upward rotation effectively fixes the body connecting seat 1 and the body housing 5 to the top of the elevator car. The first drive motor 3, located in the middle of the body connecting seat 1, is then activated. This drives the body housing 5, connected to its lower end, to rotate at the lower end of the body connecting seat 1. Due to the rotating connection structure between the guide ring 6 and the body connecting seat 1, the body housing 5 is guided and limited by the guide ring 6 and the guide plate 4 during rotation, preventing damage to the body housing 5 during movement. In the event of a deviation, the horizontally rotating housing 5 drives the internal mounting housing 12 to perform horizontal alignment at the top of the elevator car. Simultaneously, the second drive motor 9, located at the rear of the housing 5, is activated, causing the drive mounting plate 10 connected to its front end to rotate inside the housing 5. Due to the rotational connection structure between the anti-deviation guide block 11 and the housing 5, the drive mounting plate 10 is guided and limited during rotation, improving its rotational stability. The rotating drive mounting plate 10 then drives the internally connected mounting housing 12 to rotate clockwise inside the housing 5, causing the mounting housing 12 to drive the infrared sensor 19, laser sensor 20, and image sensor located on its right side. The identification module 21 is displaced downwards, allowing operators to adjust the monitoring positions of the infrared sensor 19, laser sensor 20, and image recognition module 21 according to the device's usage requirements. This also facilitates calibration of the support positions of the infrared sensor 19, laser sensor 20, and image recognition module 21 based on the space conditions of different elevator cars, ensuring that the monitoring effect of the device is not affected and improving its versatility. After adjusting the monitoring positions of the infrared sensor 19, laser sensor 20, and image recognition module 21, the mobile battery 7 is placed inside the housing 5, and the battery cover 8 is placed over the mobile battery 7. At this point, the intelligent controller 18 installed inside the housing 12 is then installed. Driven by electricity, the infrared sensor 19, laser sensor 20, and image recognition module 21 monitor the interior of the elevator car in real time through infrared, laser, smoke detection, and image acquisition via a protection board 22. The infrared sensor 19 detects the presence of living beings inside the car using infrared technology. It boasts high sensitivity and accuracy, enabling a rapid response. The laser sensor 20 works in conjunction with the infrared sensor 19 to further enhance detection accuracy, particularly for identifying children and the elderly. The laser sensor 20 provides more precise distance and shape information, helping to distinguish between individuals of different age groups. Meanwhile, the image recognition module 21 employs a new generation of image recognition algorithms.Supporting higher resolution image formats, incorporating a light compensation algorithm, and supporting environmental setting modes, the system can accurately identify passenger states such as standing or falling. The image recognition module 21 can capture images of passenger activity within the car. Furthermore, the image recognition module 21 features light compensation to adapt to image acquisition under different lighting conditions. The smoke sensor 23, in conjunction with the infrared sensor 19, laser sensor 20, and image recognition module 21, can more accurately determine abnormal situations within the car. When the smoke sensor 23 detects smoke and detects abnormal passenger behavior, it can more likely determine that a fire or other emergency has occurred within the car, thereby improving the accuracy and reliability of the alarm. After completing the above information collection, the data collected by the infrared sensor 19, laser sensor 20, image recognition module 21, and smoke sensor 23 is transmitted to the intelligent controller 18. The intelligent controller 18 then processes and analyzes the input data using its built-in algorithm to determine the passenger's state. Simultaneously, the intelligent controller 18 transmits the data from the infrared sensor 19, laser sensor 20, image recognition module 21, and smoke sensor 23 to the intelligent controller 18. Data collected by sensors 21 and 23 is fused and analyzed using deep learning algorithms to determine passenger status, such as standing or falling. When an anomaly is detected, the intelligent controller 18 sends a corresponding control command via the data connection cable 17 connected to the left side of the housing 12. The data connection cable 17 then transmits the command, ensuring that the elevator control panel emits an audible and visual alarm to alert personnel inside and outside the elevator. This prevents dangerous actions by personnel from affecting the safe operation of the elevator. Simultaneously, based on the data obtained from this device, the control panel can effectively display the elevator's direction of travel and current floor to passengers inside, and can display real-time abnormal conditions, such as overload or fire alarms. This allows for early monitoring and prevention of elevator operation safety, improving the stability of the elevator car and minimizing the possibility of accidents.
