Abstract
Description
Technical Field
[0001] This invention relates to the field of elevator technology, and specifically to a smart elevator with radar detection and fall warning function. Background Technology
[0002] When an elevator starts or stops, it generates vertical acceleration, which can make passengers feel weightless or overweight. This is especially true when there are many floors and frequent starts and stops. Repeated weightlessness and overweight can cause discomfort or dizziness and falls for elderly or frail passengers. After falling, these passengers may find it difficult to press the emergency call button to call for help or get out of the elevator on their own. They may even be unable to send out a distress signal after falling and losing consciousness, leaving them trapped inside the elevator without rescue. Moreover, if these passengers fall at night or during periods of low passenger traffic, they are even less likely to be noticed by other passengers.
[0003] Currently, elevator technology lacks corresponding monitoring and alarm measures for special emergencies such as passengers being unable to get up for a long time after falling or fainting, which often leads to passengers being stranded in the elevator for a long time without being able to receive assistance. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, this invention provides a smart elevator with radar detection and fall warning functions.
[0005] The technical solution adopted by this invention to solve its technical problem is:
[0006] A smart elevator with radar-based fall detection and early warning function includes an elevator car slidably installed in an elevator shaft, an elevator control system for controlling the operation of the elevator car, and a property monitoring platform located in a monitoring room. The property monitoring platform is connected to a display module, an alarm module, and a monitoring transponder. The elevator car is equipped with an operation status detection system for monitoring the elevator's operation. The operation status detection system includes a vibration detection module for detecting elevator car vibration and a speed detection module for detecting the elevator car's operating speed. The elevator car is equipped with a camera for capturing images of the interior and a fall-sensing radar for detecting whether a passenger has fallen inside the elevator car. The fall-sensing radar is connected to a fall monitoring device, which is connected to the elevator control system, the property monitoring platform, and the operation status detection system. The fall monitoring device sends a fall control command to the elevator control system and a fall alarm signal to the property monitoring platform after a passenger falls.
[0007] In this invention, the operating status detection system includes a top-rush detection module installed on the car top and a bottom-squatting detection module installed on the car bottom.
[0008] In this invention, the fall monitoring device is installed on the top of the elevator car. The fall monitoring device includes a monitoring box and a control module. The monitoring box is installed on the top of the elevator car. The control module is installed inside the monitoring box and is connected to the elevator control system, the property monitoring platform, the camera, the fall sensing radar, the vibration detection module, and the speed detection module.
[0009] In this invention, an intercom is provided inside the elevator car, and the control module is connected to the intercom.
[0010] In this invention, the control module is connected to an advertising playback module.
[0011] In this invention, the control module is electrically connected to a communication unit, and the control module is connected to the property monitoring platform through the communication unit.
[0012] In this invention, the communication unit is wirelessly connected to a remote service platform.
[0013] In this invention, the control module is connected to a GPS positioning module.
[0014] In this invention, the elevator car includes a car floor, a car wall located on the upper part of the car floor, and a car top located on the top of the car wall. The fall detection radar is installed at the bottom center of the car top.
[0015] The beneficial effects of this invention are as follows: This invention installs a fall-sensing radar inside the elevator car. When the fall-sensing radar detects a passenger falling, the fall monitoring device sends a fall control command to the elevator control system and detection information from the operation status detection system and a fall alarm signal to the property monitoring platform. Upon receiving the fall control command, the elevator control system controls the elevator car's operation accordingly. Upon receiving the fall alarm signal and the detection information from the operation status detection system, the property monitoring platform uses an alarm module to issue an audible and visual alarm to alert property staff. Property staff can then view the images captured by the camera and the detection information from the operation status detection system through a display module to observe the fallen passenger's condition and the elevator car's operation. This allows for a quick understanding of the fall alarm situation and timely implementation of appropriate countermeasures to assist the fallen passenger, thus improving passenger safety when using the elevator.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0026] Reference Figure 1-8 A smart elevator with radar-based fall detection and early warning function includes an elevator car 1 slidably installed in the elevator shaft, an elevator control system 2 for controlling the operation of the elevator car 1, and a property monitoring platform 3 located in the monitoring room. The elevator car 1 is equipped with an operation status detection system 4 for monitoring the elevator's operation. The operation status detection system 4 includes a top-overhead detection module installed on the car top 13, a bottom-underhead detection module installed on the car bottom 11, a vibration detection module for detecting the vibration of the elevator car 1, and a speed detection module for detecting the operating speed of the elevator car 1. The top-overhead detection module and the bottom-underhead detection module both use proximity switches. The speed detection module is an acceleration detector, which is installed on the top of the car top 13 to detect the acceleration of the elevator operation. The elevator operating parameters are monitored by the operation status detection system 4. When a fault signal is detected in the elevator operation, the fall monitoring device 7 sends a fault signal to the property monitoring platform 3 to notify the property staff of the property monitoring platform 3 to handle the fault. If the property monitoring platform 3 does not respond within a specified time, the fall monitoring device 7 will actively send the fault information to the remote service platform 70 for alarm handling, so as to ensure the reliability of elevator fault rescue and improve the safety performance of the elevator.
[0027] Furthermore, the elevator car 1 is equipped with a camera 5 for capturing images inside the elevator car 1 and a fall detection radar 6 for detecting whether a passenger has fallen inside the elevator car 1. The camera 5 and the fall detection radar 6 are installed on the ceiling inside the elevator car 1. The fall detection radar 6 is connected to a fall monitoring device 7, which is connected to the elevator control system 2, the property monitoring platform 3, and the operation status detection system 4. The fall monitoring device 7 is used to send a fall control command to the elevator control system 2 and a fall alarm signal and the detection information from the operation status detection system 4 to the property monitoring platform 3 after a passenger falls.
[0028] In a preferred embodiment, the fall monitoring device 7 is installed on the top of the elevator car 1. The fall monitoring device 7 includes a monitoring box and a control module 71. The monitoring box is bolted to the top of the elevator car 1. The control module 71 is installed in the monitoring box and is connected to the elevator control system 2, the property monitoring platform 3, the camera 5, the fall-sensing radar 6, the top-overhead detection module, the bottom-overhead detection module, the vibration detection module, and the speed detection module. When a passenger falls in the elevator car 1, the control module 71 sends a fall control command to the elevator control system 2 and sends the detection information from the operation status detection system 4 and a fall alarm signal to the property monitoring platform 3. After receiving the fall control command, the elevator control system 2 controls the operation of the elevator car 1 according to the fall control command. After receiving the fall alarm signal and the detection information from the operation status detection system 4, the property monitoring platform 3 uses the alarm module 32 to issue an audible and visual alarm to remind property staff. Property staff can view the images captured by the camera 5 and the detection information from the operation status detection system 4 through the display module 31 to observe the status of the fallen passenger and the operation of the elevator car 1.
[0029] In a preferred embodiment, the property monitoring platform 3 is a service device for property staff. Property staff can use this platform to manage and record elevator information and passenger profile information. The passenger profile information includes the passenger's name, age, facial information, address, emergency contact number, and other information. The property monitoring platform 3 is connected to a display module 31, an alarm module 32, and a monitoring transponder 33. The monitoring transponder 33 is the monitoring intercom in the elevator five-way intercom system. The background display module 31 is a background monitor used to display images inside the elevator car 1, passenger records, elevator information, etc. The alarm module 32 is an audible and visual alarm. When the property monitoring platform 3 receives a fall alarm signal, the alarm module 32 emits an audible and visual alarm signal to remind property staff of the alarm situation, enabling them to handle the fall alarm signal in a timely manner. At this time, the property monitoring platform 3 displays information such as the elevator information that issued the fall alarm signal, the fall passenger record information, the images inside the elevator car 1, and the detection information from the operation status detection system 4 through the background display module 31, allowing property staff to understand the alarm situation in a timely manner. The monitoring transponder 33 is the property intercom in the elevator five-way intercom system. Property staff can communicate with the intercom 8 through the monitoring transponder 33 to communicate with the fall passenger and understand the current situation.
[0030] In a preferred embodiment, the elevator car 1 is equipped with an intercom 8, which is the car intercom in the elevator's five-way communication system. It is located on the selection panel. The control module 71 is connected to the intercom 8. When the fall detection radar 6 detects that a passenger has fallen, the control module 71 simultaneously activates the intercom 8, causing the intercom 8 to send a communication request to the monitoring transponder 33. This allows the fallen passenger to communicate with property staff through the intercom 8. Even if the fallen passenger is unconscious and unable to communicate, the ringing sound emitted by the monitoring transponder 33 when the intercom 8 sends a communication request to the monitoring transponder 33 can still serve as a reminder to property staff. Thus, the audible and visual alarm emitted by the alarm module 32 and the ringing sound emitted by the monitoring transponder 33 provide a dual reminder effect.
[0031] In a preferred embodiment, the control module 71 is connected to a face recognition module 9, which is connected to a camera 5. After the fall detection radar 6 detects a passenger falling, the control module 71 controls the face recognition module 9 to perform face recognition on the fallen passenger. Then, the control module 71 retrieves the passenger file information of the fallen passenger based on the face recognition result sent by the face recognition module 9 and sends it to the property monitoring platform 3, so that property staff can obtain the passenger file information of the fallen passenger and promptly notify the emergency contact person of the fallen passenger after understanding the relevant information of the fallen passenger.
[0032] In this embodiment, the control module 71 is connected to an information storage module 73, and the face recognition module 9 is connected to the information storage module 73. The information storage module 73 is used to store the working information of the control module 71 and passenger file information, etc. The control module 71 can periodically download and update the passenger file information recorded in the information storage module 73 from the property monitoring platform 3. When the face recognition module 9 performs face recognition on a passenger, the face recognition module 9 performs face recognition on the fallen passenger based on the face information captured by the camera 5 and the face information recorded in the passenger file information in the information storage module 73.
[0033] In a preferred embodiment, the control module 71 is connected to an advertising playback module 10, which is installed inside the elevator car 1. The advertising playback module 10 is an advertising playback device located within the elevator car 1. Further, the advertising playback module 10 includes a display screen module, a speaker, playback content storage, and a playback controller. The playback controller is connected to the display screen module, the speaker, and the control module 71. During normal elevator use, the advertising playback module 10 plays advertisements normally to generate advertising revenue. When the fall detection radar 6 detects a passenger falling, the control module 71 controls the advertising playback module 10 to play a video demonstrating how to respond to a fall, allowing the fallen passenger to refer to the video for appropriate actions. The response video is recorded by the elevator manufacturer and stored in the playback content storage. The response video includes a self-rescue teaching video and an alarm cancellation teaching video. The self-rescue teaching video demonstrates the actions of a passenger in self-rescue after a fall using animation, while the alarm cancellation teaching video demonstrates the action of a passenger pressing the alarm cancellation button 50 to allow the elevator control system 2 to control the elevator car 1 to resume normal operation.
[0034] In a preferred embodiment, the control module 71 is connected to a ventilation module 20, a lighting module 30, and a backup power module 40. The ventilation module 20 is a ventilation device installed on the elevator car 1, which can introduce fresh air into the elevator car 1, ensure the oxygen content of the air inside the elevator car 1, and provide sufficient oxygen for passengers to breathe. The lighting module 30 can provide lighting for the elevator car 1, illuminating the environment inside the elevator car 1, so that the car has a good lighting and ventilation environment. The backup power module 40 is installed on the top of the elevator car 1 via a battery box 801, which is bolted to the top of the elevator car 1 roof 13. The backup power module 40 is connected to the elevator's power system for charging. The backup power module 40 is connected to the control module 71, intercom 8, fall detection radar 6, face recognition module 9, advertising playback module 10, ventilation module 20, lighting module 30, communication unit 60, and GPS positioning module 80. The backup power module 40 provides power during power outages to ensure the normal operation of the aforementioned devices in case of unexpected situations.
[0035] In a preferred embodiment, the elevator car 1 is equipped with an alarm cancellation button 50 located next to the elevator floor selector. The alarm cancellation button 50 is connected to the control module 71 and is used to cancel the fall alarm signal, allowing the elevator control system 2 to resume normal elevator operation. If a passenger is able to stand up independently after a fall and feels unharmed, or if there are other passengers in the elevator, the fallen passenger or their companion can press the alarm cancellation button 50 to cancel the fall alarm signal. This allows the control module 71 to send an alarm cancellation control command to the elevator control system 2. The elevator control system 2 then cancels the currently executing fall control command based on this command and resumes normal elevator operation. Furthermore, during the sending of the alarm cancellation control command, the control module 71 simultaneously sends the fall alarm signal and facial recognition results to the property monitoring platform 3 and activates the intercom 8 to make an external call for assistance, allowing property staff to understand the passenger's situation and inquire whether further assistance is needed.
[0036] In a preferred embodiment, the control module 71 is electrically connected to a communication unit 60. The control module 71 is connected to the property monitoring platform 3 via the communication unit 60, which supports both wired and wireless communication. The communication unit 60 is wirelessly connected to a remote service platform 70, which is the elevator manufacturer's service terminal. When the control module 71 detects a malfunction in the elevator through the operation status detection system 4, it simultaneously sends an alarm signal to both the property monitoring platform 3 and the remote service platform 70. This notifies the property staff of the property monitoring platform 3 and the on-duty personnel of the remote service platform 70 to handle the malfunction. This notification allows the property staff of the property monitoring platform 3 and the on-duty personnel of the remote service platform 70 to communicate and discuss solutions to the elevator malfunction, thereby resolving the malfunction as quickly as possible, ensuring the reliability of elevator malfunction rescue and passenger fall rescue, and improving the elevator's safety performance.
[0037] In a preferred embodiment, the control module 71 is connected to a GPS positioning module 80, which provides accurate elevator location information to the remote service platform 70. The remote service platform 70 can use the GPS positioning module 80 to know the location of the faulty elevator so as to handle the faulty elevator in a timely manner.
[0038] In a preferred embodiment, the elevator car 1 includes a car bottom 11, a car wall 12 located on the upper part of the car bottom 11, and a car top 13 located on the top of the car wall 12. The car bottom 11, car wall 12, and car top 13 are connected by bolts. The elevator car 1 can refer to the existing elevator car 1 structure. In this embodiment, the fall detection radar 6 is installed at the bottom center of the car top 13. The car top 13 includes a top frame 131 and a decorative panel 132 located at the bottom of the top frame 131. The decorative panel 132 is fixed to the top frame 131 by bolts. The lighting module 30 is an LED ring light installed at the bottom of the decorative panel 132. The LED ring light is fixed to the decorative panel 132 by bolts. The LED ring light can provide uniform lighting effect and ensure the lighting quality inside the elevator car 1. The LED ring light can be circular or square. In this embodiment, a square ring light is preferred. The LED ring light can be purchased from the market, so it will not be described in detail. To ensure the aesthetics of the car roof 13, the fall detection radar 6 is located within the ring of LED lights, placing it at the center of the LED ring light ring. This creates an aesthetically pleasing shape at the bottom of the car roof 13, making the fall detection radar 6 less obtrusive and ensuring the overall aesthetics of the bottom of the car roof 13.
[0039] In a preferred embodiment, the fall detection radar 6 includes a sensing housing 61, a fall detection module 62, and a radar cover 63. The sensing housing 61 is fixedly mounted on the bottom of the decorative panel 132 using a first bolt 100. The interior of the sensing housing 61 is a mounting cavity 611. The fall detection module 62 is fixed in the mounting cavity 611 using a second bolt. The bottom of the sensing housing 61 is the opening of the mounting cavity 611. The radar cover 63 is connected to the bottom of the sensing housing 61 and is used to close the opening at the bottom of the mounting cavity 611.
[0040] To facilitate the connection between the fall detection radar 6 and the control module 71, the decorative panel 132 has a centrally located mounting opening 134 that extends from top to bottom through the decorative panel 132. The top of the sensing housing 61 has a wire guide cover 612 integrally formed with the sensing housing 61. The upper end of the wire guide cover 612 passes through the mounting opening 134, and a reinforcing nut 64 is threaded onto the upper end of the wire guide cover 612. The reinforcing nut 64 fits onto the top surface of the decorative panel 132, and the use of the reinforcing nut 64 against the top surface of the decorative panel 132 enhances the installation quality of the fall detection radar 6 on the decorative panel 132.
[0041] In a preferred embodiment, the fall detection module 62 is connected to a connecting cable 65. The cable guide housing 612 has a cable groove communicating with the mounting cavity 611, and a cable through hole communicating with the cable groove. One end of the connecting cable 65 is electrically connected to the fall detection module 62, and the other end passes through the cable groove and the cable through hole before connecting to the control module 71. Furthermore, a waterproof cable connector 68 is installed in the cable through hole, and the connecting cable 65 passes through the waterproof cable connector 68, which prevents wind from entering the sensor housing 61.
[0042] In a preferred embodiment, the mounting cavity 611 is provided with a plurality of mating through holes, and the decorative plate 132 is provided with a plurality of mating screw holes, each mating screw hole corresponding to a mating through hole. The screw section of the first bolt 100 passes through the mounting through hole and is threadedly connected to the mating screw hole to fix the sensing housing 61.
[0043] In a preferred embodiment, the wiring housing 612 is externally fitted with a first elastic washer 66 and a second elastic washer 67. The bottom surface of the first elastic washer 66 is in contact with the top surface of the sensing housing 61, and the top surface is in contact with the bottom surface of the decorative panel 132. The first elastic washer 66 has a first mating through hole for the threaded section of the first bolt 100 to pass through. The bottom surface of the second elastic washer 67 is in contact with the top surface of the decorative panel 132, and the top surface is in contact with the bottom surface of the reinforcing nut 64. Both the first elastic washer 66 and the second elastic washer 67 are made of rubber or silicone. The first elastic washer 66 and the second elastic washer 67 are elastic and are used to fill the mating gap to prevent wind from entering the elevator car 1 through the installation opening 134.
[0044] In a preferred embodiment, the cavity wall of the mounting cavity 611 is provided with a snap groove 613, and the top of the radar cover plate 63 is provided with a buckle 631 that can be snapped into the snap groove 613. The buckle 631 is snapped into the snap groove 613, so that the radar cover plate 63 is installed on the bottom of the sensing housing 61.
[0045] In a preferred embodiment, the fall detection module 62 is a fall detection circuit board integrating a millimeter-wave detection module, a processor, and a fall communication interface. The processor is connected to the millimeter-wave detection module, the fall communication interface, and the control module 71. The millimeter-wave detection module can use a Texas Instruments IWR6843 millimeter-wave sensor. Detecting whether someone has fallen using millimeter-wave technology is existing technology and will not be described in detail. The processor determines whether a passenger has fallen based on the detection information from the millimeter-wave detection module and then sends a fall recognition signal to the control module 71. The fall detection circuit board has a through hole, and the mounting cavity 611 has a corresponding mating screw hole. The second bolt passes through the through hole and is threaded into the mating screw hole, thereby fixing the fall detection module 62 in the mounting cavity 611. One end of the connecting cable 65 has a mating communication interface 651 that mates with the fall communication interface, and the other end has a first wiring port that connects to the control module 71.
[0046] The following are the instructions for using the smart elevator:
[0047] Step 1: After the fall detection radar 6 detects a passenger falling, the fall detection radar 6 sends a fall recognition signal to the control module 71.
[0048] Step 2: After receiving the fall detection signal, the control module 71 automatically sends a fall control command to the elevator control system 2, a fall alarm signal to the property monitoring platform 3, and detection information from the operation status detection system 4. The elevator control system 2, based on the fall control command, controls the elevator car 1 to move to a preset floor, then stops the elevator car 1 and opens the elevator door to allow ventilation inside and outside the elevator car 1 or to allow passengers to exit the elevator and wait for rescue. The preset floor can be a first-floor floor, as first-floor floors have high passenger flow, making it easier for outsiders to report a passenger fall inside the elevator car 1, and also facilitating timely arrival of property staff to rescue the passenger. After receiving the fall alarm signal and the detection information from the operation status detection system 4, the control platform 3 uses the alarm module 32 to issue an audible and visual alarm to remind property staff. Property staff can view the images captured by the camera 5 and the detection information from the operation status detection system 4 through the display module 31 to observe the state of the fallen passenger and the operation status of the elevator car 1. Observing the images captured by the camera 5 allows property staff to understand the current situation of the fallen passenger, such as whether the fallen passenger is still conscious and whether he / she can still move. Observing the detection information from the elevator car 1 allows property staff to know whether the elevator malfunctioned when the passenger fell, thus making a preliminary judgment on whether the passenger fell due to an elevator malfunction.
[0049] In step 2, after receiving the fall detection signal, the control module 71 controls the face recognition module 9 to compare the image captured by the camera 5 with the face information recorded in the passenger file information in the information storage module 73. If the face match is successful, the fall alarm signal sent by the control module 71 includes the passenger file information of the fallen passenger. After receiving the fall alarm signal, the property monitoring platform 3 can display the passenger file information on the display module 31, allowing property staff to quickly understand the passenger's information and conveniently notify the fallen passenger's emergency contact by phone. If the face match fails, the passenger is identified as a stranger, and the fall alarm signal sent by the control module 71 to the property monitoring platform 3 does not include the fallen passenger's passenger file information. Property staff can only learn about the passenger's relevant information by communicating with the fallen passenger.
[0050] In step 1, after the control module 71 receives the fall detection signal, the control module 71 controls the advertising playback module 10 to play a response video so that passengers who are still able to move after a fall can perform self-rescue actions or deactivate the alarm based on the instructional animation in the response video. In addition, when the control module 71 detects that the monitoring transponder 33 is communicating remotely with the intercom 8, the control module 71 controls the advertising playback module 10 to pause the playback of the response video to avoid affecting the communication between the monitoring transponder 33 and the intercom 8.
[0051] In step 2, when the control module 71 sends a fall alarm signal to the property monitoring platform 3, the control module 71 can simultaneously activate the intercom 8 to communicate with the monitoring transponder 33 of the property monitoring platform 3. This allows the property staff to be alerted by the communication request sound generated by the monitoring transponder 33 when the intercom 8 requests communication with it, thus providing a double alert and enabling property staff to quickly receive the communication request, learn that a passenger has fallen in the elevator car 1, and then communicate with the fallen passenger through the monitoring transponder 33 for a rapid response. Fall response measures can include remote communication between the monitoring transponder 33 and the intercom 8. Property staff can use this to remotely understand the cause of the fall and inquire if the passenger needs assistance. If the passenger does not respond, property staff will rush to the scene to provide rescue, thus preventing the passenger from being trapped after falling in the elevator. Additionally, after understanding the situation from the passenger, property staff can rush to the scene to provide appropriate services, such as notifying the passenger's emergency contact or bringing relevant medications.
[0052] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by essentially the same means is within the protection scope of the present invention.

One end of the connecting cable (65) is electrically connected to the fall detection module (62), and the other end passes through the cable threading groove and the cable threading through hole in sequence before being connected to the control module (71). The fall detection module (62) is a fall detection circuit board that integrates a millimeter wave detection module, a processor, and a fall communication interface. The processor is connected to the millimeter wave detection module, the fall communication interface, and the control module (71) respectively. The fall monitoring device (7) is installed on the top of the elevator car (1). The fall monitoring device (7) includes a monitoring box and a control module (71). The monitoring box is fixedly installed on the top of the elevator car (1). The control module (71) is installed in the monitoring box. The control module (71) is connected to the elevator control system (2), the property monitoring platform (3), the camera (5), the fall sensing radar (6), the top detection module, the bottom detection module, the vibration detection module, and the speed detection module. When a passenger falls in the elevator car (1), the control module (71) sends a fall control signal to the elevator control system (2). The elevator control system (2) sends the control command and the detection information of the operation status detection system (4) and the fall alarm signal to the property monitoring platform (3). After receiving the fall control command, the elevator control system (2) controls the operation of the elevator car (1) according to the fall control command. After receiving the fall alarm signal and the detection information of the operation status detection system (4), the property monitoring platform (3) uses the alarm module (32) to issue an audible and visual alarm to remind the property staff. The property staff can view the images captured by the camera (5) and the detection information of the operation status detection system (4) through the display module (31) to observe the status of the fallen passenger and the operation status of the elevator car (1). The property monitoring platform (3) is connected to a display module (31), an alarm module (32), and a monitoring transponder (33). The elevator car (1) is equipped with an intercom (8). The control module (71) is connected to the intercom (8). When the fall detection radar (6) detects that a passenger has fallen, the control module (71) simultaneously activates the intercom (8) so that the intercom (8) sends a communication request to the monitoring responder (33) so that the fallen passenger can communicate with the property staff through the intercom (8). Even if the fallen passenger is unconscious and cannot communicate, the ringing sound emitted by the monitoring responder (33) when the intercom (8) sends a communication request to the monitoring responder (33) can also serve as a reminder to the property staff. Thus, the sound and light alarm emitted by the alarm module (32) and the ringing sound emitted by the monitoring responder (33) serve as a double reminder. The control module (71) is connected to a face recognition module (9), which is connected to a camera (5). After the fall detection radar (6) detects that a passenger has fallen, the control module (71) controls the face recognition module (9) to perform face recognition on the fallen passenger. Then, the control module (71) retrieves the passenger file information of the fallen passenger based on the face recognition result sent by the face recognition module (9) and sends it to the property monitoring platform (3), so that the property staff can know the passenger file information of the fallen passenger and facilitate the property staff to promptly notify the emergency contact person of the fallen passenger after understanding the relevant information of the fallen passenger. The control module (71) is connected to a GPS positioning module (80); The control module (71) is connected to the advertising playback module (10). After the fall detection radar (6) detects that a passenger has fallen, the control module (71) controls the advertising playback module (10) to play the response video after the passenger falls, so that the fallen passenger can refer to the response video to make corresponding actions. The response video is recorded by the elevator manufacturer and stored in the playback content storage. The response video includes a self-rescue teaching video and an alarm cancellation teaching video. The self-rescue teaching video is used to demonstrate the self-rescue actions of the passenger after falling through animation. The alarm cancellation teaching video is used to demonstrate the actions of the passenger pressing the alarm cancellation button (50) to allow the elevator control system (2) to control the elevator car (1) to resume normal operation through animation. The control module (71) is connected to the ventilation module (20), the lighting module (30), and the backup power module (40); the backup power module (40) is connected to the control module (71), the intercom (8), the fall detection radar (6), the face recognition module (9), the advertising playback module (10), the ventilation module (20), the lighting module (30), the communication unit (60), and the GPS positioning module (80); The elevator car (1) is equipped with an alarm release button (50), which is connected to the control module (71). The alarm release button (50) is used to release the fall alarm signal, so that the elevator control system (2) controls the elevator to resume normal operation. If the passenger can stand up on his own after falling and feels that he is okay, or if there are passengers in the elevator, the fallen passenger or the passengers in the elevator can press the alarm release button (50) to release the fall alarm signal, so that the control module (71) sends an alarm release control command to the elevator control system (2). The elevator control system (2) cancels the fall control command being executed according to the alarm release control command and controls the elevator to resume normal operation. Moreover, during the process of sending the alarm release control command, the control module (71) normally sends the fall alarm signal and face recognition results to the property monitoring platform (3) and starts the intercom (8) to make a call for help to the outside, so that the property staff can understand the passenger's real situation and ask if he still needs help.
