[0009] The present invention also discloses an automatic emergency rescue method for an elevator, comprising the automatic emergency rescue device for an elevator as described above, wherein the method comprises:

[0010] A. When the human body sensing device detects that someone enters the elevator, the control module transmits the signal to the delay module. If the passenger does not operate for a long time after entering the elevator, the delay module reaches the delay time. After receiving the signal from the delay module, the control module sends an alarm signal to the alarm device to issue an alarm signal;

[0011] B. When the human body sensing device detects that someone has entered the elevator, and the elevator electronic control system receives the signal that the elevator is rising or falling, and sends the signal to the control module, if the passenger faints in the car, the camera device detects that the person is lying flat, and then transmits the alarm signal to the control module, and the control module sends the alarm signal to the alarm device to issue an alarm signal;

[0012] C. When the human body sensing device detects that someone has entered the elevator, and the elevator electronic control system receives the signal of the elevator rising or falling and sends the signal to the control module, if the passenger faints in the car and leans against the car wall, and the control module receives the signal from the elevator electronic control system, the elevator has reached the designated floor and transmits the signal to the delay module through the control module, the first human body sensing device does not sense that the passenger has walked out of the elevator and the second human body sensing device senses that the passenger is still in the car, after the delay module reaches the delay time, the control module receives the signal from the delay module and sends an alarm signal to the alarm device to issue an alarm signal;

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] like Figure 3 to Figure 4 As shown, the embodiment of the present application discloses an automatic emergency rescue device for an elevator, including a main controller, the main controller including a control module 6 connected to the elevator electric control system. It also includes a delay module connected to the control module 6, a first human body sensing device 1 arranged at the door of the elevator car, and a camera device 2 arranged at the top of the car. The first human body sensing device 1 and the camera device 2 are both connected to the control module 6, and it also includes an elevator ascent and descent detection module connected to the control module 6 and an alarm device 4 for sending a distress signal.

[0027] Specifically, the above-mentioned control module 6 and delay module are both existing modules, and can be implemented by a single-chip microcomputer, an industrial computer, etc. The above-mentioned first human body sensing device 1 can be a human body sensor, a life detector or an infrared sensor, etc., and the delay time of the above-mentioned delay module can be set according to the specific situation, and can be between 5 and 60 seconds, for example: 5 seconds, 10 seconds, 20 seconds, 45 seconds, 60 seconds, etc. The above-mentioned alarm device 4 can be installed in a duty room such as a security room.

[0028] like Figure 1 In one embodiment, the elevator ascent and descent detection module is a displacement detection module 3 arranged on the elevator car, and the displacement detection module 3 is connected to the control module 6.

[0029] Specifically, the displacement detection module 3 can be an ultrasonic distance measuring sensor, a laser displacement sensor, a rotary encoder, etc. The rotary encoder is installed on the elevator car, and the rotating wheel of the rotary encoder is in contact with the elevator track.

[0030] When performing elevator ascent or descent detection, when the displacement detection module 3 is installed on the elevator car, the ascent or descent of the car is judged by detecting the position change between the car and the shaft, or by the positive and negative signal changes of the rotary encoder.

[0031] like Figure 2 In one embodiment, the elevator ascent and descent detection module is an elevator electronic control system, and the main controller includes an elevator descent signal receiving terminal and an elevator ascent signal receiving terminal connected to the control module 6, and the elevator descent signal receiving terminal and the elevator ascent signal receiving terminal are respectively connected to the elevator electronic control system.

[0032] During specific operation, the elevator electronic control system transmits the obtained elevator ascending or descending signal to the control module 6, thereby detecting the current elevator operating state.

[0033] In this embodiment, it also includes an abnormal warning information prompting device 5, which is connected to the control module 6, and also includes a second human body sensing device 7 arranged inside the elevator, which is connected to the control module 6.

[0034] The above-mentioned abnormal warning information prompting device 5 can be installed in a duty room such as a security room.

[0035] When the elevator is in use, when a passenger enters the elevator alone, the first human body sensing device 1 detects that someone has entered the elevator and sends a signal to the control module 6. After the control module 6 receives the delay signal, the control module 6 starts to execute the next link. At the same time, the second human body sensing device 7 captures that someone has entered the elevator and sends a signal to the control module 6. If the passenger does not perform any operation and the elevator electronic control system has not received the operating instructions from the passenger, after the delay time is reached, the control module 6 will determine that the passenger has an emergency and send an alarm signal to the alarm device.

[0036] If the passenger enters the elevator and operates the elevator, the elevator electronic control system receives the passenger's ascent or descent command signal, the elevator starts to move and sends a signal to the control module 6, telling the control module 6 that the elevator is in an ascent or descent state at this time. During this process, if the passenger suddenly faints inside the car, if the passenger faints and lies flat inside the car, the monitoring camera device 2 can determine that the passenger has fainted by the behavioral characteristics of the human body, and send the alarm condition to the control module 6, which sends a distress signal to the alarm device 4 for an emergency call.

[0037] If the passenger faints and leans on the elevator car, the camera device 2 cannot judge whether the passenger faints by human behavior. When the control module 6 receives the end signal of the elevator's ascending or descending operation, the elevator has reached the floor required by the passenger, and the first human body sensing device 1 detects that the passenger has not come out of the elevator. The elevator is still staying on the same floor, and the second human body sensing device 7 detects that the passenger is still in the elevator car. At the same time, when the delay time set by the delay module is reached, the control module 6 sends a signal to the alarm device 4.

[0038] When the elevator stops and rises again for multiple times in a row, the passenger is always inside the elevator car, the passenger has not left the car and no other passengers have entered the elevator, the control module 6 will send an abnormal warning message to the abnormal warning message prompting device 5 to prompt the security personnel to observe whether there is any abnormal condition inside the elevator through the camera device 2 inside the elevator car.

[0039] When the elevator stops after rising to the station, the equipment detects that the passenger has not left the elevator car, and then the elevator runs in the opposite direction and executes the descending command to start picking up the next passenger, the control module 6 will send a signal to the abnormal warning information prompting device 5, prompting the security personnel to observe whether there is any abnormal condition inside the elevator through the camera inside the elevator car.

[0040] When the elevator stops and descends again for multiple times in a row, the passenger is always inside the elevator car, the passenger has not left the car and no other passengers have entered the elevator, the control module 6 will send an abnormal warning message to the abnormal warning information prompt device 5 to prompt the security personnel to observe whether there is any abnormal condition inside the elevator through the camera device 2 inside the elevator car.

[0041] When the elevator stops after descending to the station, the equipment detects that the passenger has not left the elevator car, and then the elevator runs in the opposite direction and executes the ascending command to start picking up the next passenger, the control module 6 will send a signal to the abnormal warning information prompting device 5, prompting the security personnel to observe whether there is any abnormal condition inside the elevator through the camera inside the elevator car.

[0042] This device mainly solves the problem of passengers, such as the elderly or people with physical illnesses, who suddenly suffer from high blood pressure, cerebral infarction, heart disease, epilepsy, asthma, etc. and faint in the elevator when riding the elevator alone. The elevator can automatically detect the dangerous state and send out an emergency call to the outside, thereby buying precious life time for the patient.

[0043] The present invention also discloses an automatic emergency rescue method for an elevator, and the specific method is as follows:

[0044] A. When the human body sensing device detects that someone enters the elevator, the control module 6 transmits a signal to the delay module. If the passenger does not operate for a long time after entering the elevator, after the delay module reaches the delay time, the control module 6 receives the signal from the delay module and sends an alarm signal to the alarm device 4 to issue an alarm signal;

[0045] B. When the human body sensing device detects that someone has entered the elevator, and the elevator electronic control system receives the signal that the elevator is rising or falling, and sends the signal to the control module 6, if the passenger faints in the car, the camera device 2 detects that the human body is lying flat, and then transmits the alarm signal to the control module 6, and the control module 6 sends the alarm signal to the alarm device 4 to issue an alarm signal;

[0046] C. When the human body sensing device detects that someone has entered the elevator, and the elevator electronic control system receives the signal of the elevator rising or falling and sends the signal to the control module 6, if the passenger faints in the car and leans against the wall of the car, and the control module 6 receives the signal of the elevator electronic control system, the elevator has reached the designated floor and transmits the signal to the delay module through the control module 6, the first human body sensing device 1 does not sense that the passenger has walked out of the elevator and the second human body sensing device 7 senses that the passenger is still in the car, after the delay module reaches the delay time, the control module 6 receives the signal of the delay module and sends an alarm signal to the alarm device 4 to issue an alarm signal;

[0047] D. When the elevator stops and rises again for multiple times in a row, the control module 6 receives multiple rising signals and the first human body sensing device 1 does not sense that the passenger has walked out of the elevator, while the second human body sensing device 7 senses that the passenger is still in the car, the control module 6 sends a warning signal to the abnormal warning information prompting device 5;

[0048] E. When the elevator stops after reaching the station, and the first human body sensing device 1 does not sense that a passenger has walked out of the elevator, and then the elevator runs in the opposite direction and executes a descending command to pick up the next passenger, the control module 6 sends a warning signal to the abnormal warning information prompting device 5, prompting the security personnel to observe whether there is any abnormality inside the elevator through the camera device 2;
