When the data processing device 5 judges that someone falls to the ground through the human body data acquired by the sensing mechanism, the data processing mechanism 5 sends early warning information to the elevator main control board 6, the elevator main control board 6 controls the warning mechanism to give an alarm according to the early warning information, and meanwhile, the elevator main control board 6 controls the elevator to change the running state, for example, the elevator can be controlled to stop slowly, so that further harm to passengers falling to the ground is avoided.
The utility model can effectively detect the emergency situations that the passenger cannot get up or fall down when falling down, and the like, and can give an alarm in time, thereby improving the safety of the passenger taking the elevator.
In one embodiment, the specific structure of the sensing mechanism is as follows: the sensing mechanism comprises a camera 1 fixedly arranged above the inside of the elevator car and a light curtain device 4 arranged below the inside of the elevator car, the camera 1 and the light curtain device 4 are both electrically connected with a data processing device 5, and the data processing device 5 transfers signals fed back by the camera 1 according to signals fed back by the light curtain device 4. Wherein surveillance camera head 1 is used for judging whether to have the passenger to fall to the ground through the image, and light curtain device 4 is through whether sheltered from and judge whether to have the passenger to fall to the ground, detects when light curtain device 4 and shelters from the back, transfers the signal of surveillance camera head 1 feedback again, can effectively promote the accuracy of response mechanism response result. The light curtain device 4 is mounted in the car at a suitable vertical distance from the ground, typically not more than 10 CM.
In one embodiment, the specific structure of the monitoring camera 1 is as follows: the camera 1 comprises a thermal imaging module 2 and an artificial intelligence module 3. The thermal imaging module 2 identifies the living body of the human body in the car through the difference between the temperature of the human body and the temperature of an environmental object; the artificial intelligence module 3 is used for obtaining color image data inside the car, and the data processing device 5 performs human posture recognition by using ai (intellectual intelligence) technology. The image data of two types obtained by the thermal imaging module 2 and the artificial intelligence module 3 are comprehensively analyzed and recognized, so that the recognition effect of the system on the number of the human bodies and the posture of the human bodies in the car can be effectively enhanced. In one embodiment, the monitoring camera 1 is connected to the data processing device 5 via an RJ45 communication interface and transmits image data. When the light curtain device 4 detects that the shielding is performed, a signal is sent to the data processing device 5, and after the data processing device 5 receives the signal sent by the light curtain device 4, the image data returned by the monitoring camera 5 is identified by using an AI image identification technology, including detecting whether a human body and the number of the human body exist in the car and identifying the posture of the human body. If the human body is recognized to be in the lift car and the human body presents a falling gesture, the data processing device 5 sends a signal of 'someone falls in the lift car' to the elevator main control board 6; if the human body is not identified, a 'normal' signal is sent to the elevator main control board.
In one embodiment, the specific alarm mode of the alarm mechanism is as follows: the alarm mechanism comprises a buzzer 8, and the buzzer 8 is electrically connected with the elevator main control board 6. The buzzer 8 may be located inside the car, outside the car or at the office location of the elevator supervisor.
Considering that some passengers can get up quickly after falling down, and no danger occurs, in one embodiment, the alarm mechanism includes a timer 9, the timer 9 is electrically connected with the elevator main control board 6, and the elevator main control board 6 controls the buzzer 8 to work according to a signal fed back by the timer 9. The timer 9 can be used for timing after the sensing mechanism senses that a passenger falls down, and the alarm is given when the timing result exceeds a set threshold value, so that the alarm is triggered when the passenger does not need to be rescued, and the waste of rescue resources can be avoided.
In order to be able to monitor the operating conditions of the elevator and at the same time to realize remote alarms, the alarm mechanism comprises in one embodiment a server 10 in communicative connection with the elevator main control board 6.
To enable remote alerting, in one embodiment, a server 10 is wirelessly communicatively connected with a plurality of terminals 11. The terminal 11 may be a smartphone or a computer. So that the on-duty personnel can respond to the help seeking information in time.
In one embodiment, the connection mode between the elevator main control board 6 and the server is as follows: the elevator main control board 6 is in communication connection with the server 10 through the data internet of things gateway 7.
In general, the response mode of the elevator main control board 6 to the signal transmitted by the data processing device 5 includes:
A. when the data processing device 5 sends a "someone falls down inside the car" signal and the elevator is in the landing state, the elevator remains in the open-door-parking state until the data processing device 5 sends a "normal" signal.
B. When the data processing device 5 sends a signal that someone falls down in the car and the elevator is in a door closing motion state, the elevator automatically drives to and stops at the nearest landing in the running direction, and after stopping at the landing, the door opening parking state is kept until the data processing device 5 sends a normal signal.
C. When the elevator main control board 6 continuously receives the 'someone falls down in the car' signal sent by the data processing device 5 and the preset time is exceeded, the elevator gives an alarm by sounding through the buzzer 8, and sends alarm and help-seeking information to the server 10 through the data internet of things gateway 7, and the server 10 automatically distributes the alarm and help-seeking information to the terminal 11. The preset time is calculated from the elevator main control board when the signal of 'someone falls down in the car' is received, and the calculation is executed by the timer 9, and the specific time can be set according to the requirement. After the elevator main control board 6 receives the 'normal' signal again, the timer 9 resets, the buzzer 8 stops sounding, the data internet of things gateway 7 stops sending the distress alarm information, and the elevator returns to normal operation.
D. When the data processing device 5 sends a "normal" signal and the elevator is not in the A, B, C response states described above, the elevator remains in the current operating state.
In one embodiment, the data processing device 5 is connected to the elevator control 6 via a serial communication bus.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
