Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is described in further detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the elevator safety voice prompt system shown in fig. 1 includes: the system comprises a main control panel 10, a monitoring device 20 and a voice playing device 30 which are respectively and electrically connected with the main control panel; the monitoring device is used for acquiring state information of people and sending the state information to the main control panel; the main control panel is used for comparing the character state information with the character state information stored in advance, and when the comparison result is different, the voice playing device sends out a safe voice prompt. The voice playing device comprises a power amplifier.
The embodiment of the invention adopts the safe voice prompt system additionally arranged on the elevator, firstly judges the state of a passenger, namely firstly acquires the state information of the passenger, and then judges the current state of the passenger (whether the passenger watches the mobile terminal or pays attention to other things, and does not pay attention to the elevator) by identifying the state information, and when the passenger does not pay attention to the elevator, the voice is sent out to remind the passenger of the safety of the elevator. Through the arrangement, the problem that passengers are not found due to abnormal elevators and are accidentally injured is avoided.
In this embodiment, the monitoring device 20 includes a human body sensor 301 and a camera 302, and the human body sensor is used for sending data to the main control board when detecting that someone approaches the elevator door; the camera is used for shooting people close to the elevator door to obtain the person state information.
The human body sensor detects that people approach the elevator door within a range of about 1m by utilizing an infrared heat release principle, the detention time outside the door exceeds 20s, data are sent to the main control board at the moment, and after the main control board receives the data of the people approaching the elevator door, an instruction is sent to the camera head, and the camera head is started to shoot and store the data.
Further, in this embodiment, a face image of a person is obtained, and a direction gazed by eyes of the person in the face image is compared with a pre-stored standard direction gazed by eyes of the person. Specifically, the acquired photograph is analyzed, a face image of a person in the photograph is acquired, a deviation value between the position of the direction of the eyes of the person gazing and a standard direction of the eyes of the person gazing stored in advance is calculated, and the obtained deviation value is compared with a predetermined threshold value (i.e., an angle at which the directions of the eyes of the person gazing deviate from the horizontal direct view direction), which may be 20 degrees, 45 degrees, 60 degrees, or the like. The technology for analyzing the picture is a technology commonly used in the existing picture analysis and a technology for judging the gazing direction according to human eyes, which is not a key point protected by the invention and is not described herein again.
In a further embodiment, the system further comprises a detection device 40 connected to the main control panel for detecting whether the elevator door is aligned with the car door.
Specifically, a signal generator 401 is arranged on a car door of an elevator, when a button of the elevator is pressed, the signal generator sends signals at intervals, meanwhile, a signal receiver 402 is arranged at a position corresponding to the elevator door, when the elevator car stops at a certain floor, if the signal receiver does not receive the corresponding signal, the situation that the car door of the elevator is not aligned with the elevator door is indicated, at the moment, the elevator does not open the door, and meanwhile, voice is sent to remind a passenger.
Furthermore, the signal generator is arranged in the middle of the elevator car door, so that the elevator car door is prevented from being deformed to cause misjudgment. Certainly for judging more accurately, the signal generator is provided with a plurality of, for example, the upper portions of two side doors of the elevator car are provided with the middle portions. The signal generator is arranged on one side close to the elevator door, so that the signal generator is prevented from being touched by people.
Further, the present invention also provides a control method of an elevator safety voice prompt system, which includes the following steps, please refer to fig. 2:
s100, the monitoring device acquires the person state information close to the elevator door and sends the person state information to a main control board;
s200, the main control board compares the received person state information with the pre-stored person state information to obtain a comparison result;
s300, when the comparison result exceeds a preset threshold value, the voice playing device sends out a safe voice prompt.
In summary, the invention provides a safety voice prompt system and a control method thereof, by adding the safety voice prompt system to a lift elevator, firstly, the state of a passenger is judged, namely, the state information of the passenger is firstly obtained, and then, the current state of the passenger is judged by identifying the state information, and when the passenger is found not to pay attention to the lift elevator, a voice is given out to remind the passenger of the safety of the lift elevator. Through the arrangement, the problem that passengers are not found due to abnormal elevators and are accidentally injured is avoided.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
