Abstract
The invention belongs to the technical field of elevator protection systems, and particularly relates to a method for identifying an electric vehicle through a light curtain, which comprises the following steps: step one, a detection object enters an elevator car, and infrared light emitted by a light curtain is intercepted when the detection object enters the elevator car; recording the height position of the intercepted infrared ray; step three, continuously executing the step two until the shielding is finished; and step four, analyzing and judging whether the detection object is the electric vehicle or not according to the height positions of all recorded intercepted infrared light rays. The invention overcomes the defects of the prior art, and the algorithm can immediately send out an alarm and open the door for a long time when judging that the electric vehicle is driven, so that a passenger has a safe passenger elevator riding environment.
Description
Technical Field
The invention belongs to the technical field of elevator protection systems, and particularly relates to a method for identifying an electric vehicle.
Background
At present, high-rise residences are generally provided with elevators, some residents are convenient to charge and electric vehicles are convenient to charge, the electric vehicles are conveyed to the high rise through the elevators, the indoor charging is convenient, or the electric vehicles are placed in a corridor, however, the fire risk is caused by the charging of the indoor electric vehicles, the electric vehicles are placed in the corridor, the use of a fire fighting passageway is influenced, the electric vehicles conveyed through the elevators can occupy the space in an elevator car, and the use of the elevators by other residents is influenced;
in the prior art, the database comparison is also carried out after the shooting is carried out by using the camera, and the mode that the electric vehicle is prevented from entering the interior after the electric vehicle is judged, but the situations that the elevator cannot be used by mistake or cannot be identified and the like easily occur, so that the use of the elevator of residents can be influenced or the prevention purpose cannot be achieved.
Disclosure of Invention
The invention aims to provide a method for identifying an electric vehicle through a light curtain, which overcomes the defects of the prior art, provides a function of judging the electric vehicle for an elevator, and can immediately send out an alarm and open a door for a long time when judging that the electric vehicle is driven through the algorithm, so that a passenger has a safe passenger elevator riding environment.
In order to solve the problems, the technical scheme adopted by the invention is as follows:
a method of recognizing an electric vehicle, which analyzes a detection object in a monitoring range using a light curtain and determines whether the detection object is the electric vehicle, comprising the steps of:
step one, a detection object enters an elevator car, and infrared light emitted by a light curtain is intercepted when the detection object enters the elevator car;
recording the height position of the intercepted infrared ray;
step three, continuously executing the step two until the shielding is finished;
and step four, analyzing and judging whether the detection object is the electric vehicle or not according to the height positions of all recorded intercepted infrared light rays.
Further, in the method for identifying an electric vehicle, the method further includes the step five: and when the detected object is judged to be the electric vehicle, giving an alarm, prompting that the electric vehicle is prohibited from entering the interior, and continuously broadcasting for three times.
Further, in the method for identifying an electric vehicle, in the fifth step, if the electric vehicle exits the elevator car during the alarm, the alarm sound is cancelled.
Further, in the method for identifying an electric vehicle, the method further includes the steps of: and when the detected object is judged to be the electric vehicle, the elevator is kept to be opened for a long time within the preset time until the electric vehicle exits from the elevator car.
Further, in the method for identifying an electric vehicle, in the sixth step, if the electric vehicle exits the elevator car within the preset time, the waiting for the preset time is cancelled.
Further, in the method for identifying an electric vehicle, the preset time is 20 seconds.
Compared with the prior art, the invention has the following beneficial effects:
the method for identifying the electric vehicle analyzes and judges whether the detected object is the electric vehicle or not through the height position of the light curtain which is shielded, and immediately gives an alarm and opens the door for a long time when judging that the electric vehicle is driven, so that a passenger has a safe passenger elevator riding environment; the elevator light curtain system and the control system are adopted, so that additional modification is not needed, the modification cost is reduced, and the elevator light curtain system is more economical and practical.

FIG. 1 is a flow chart of a process by the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides a method for identifying an electric vehicle, which analyzes a detection object in a monitoring range using a light curtain and determines whether the detection object is an electric vehicle, comprising the steps of:
step one, a detection object enters an elevator car, and infrared light emitted by a light curtain is intercepted when the detection object enters the elevator car;
recording the height position of the intercepted infrared ray;
step three, continuously executing the step two until the shielding is finished;
analyzing and judging whether the detection object is an electric vehicle or not according to the height positions of all recorded intercepted infrared light rays;
step five: and when the detected object is judged to be the electric vehicle, giving an alarm, prompting that the electric vehicle is prohibited from entering the interior, and continuously broadcasting for three times. If the electric vehicle exits the elevator car during the alarm period, the alarm prompt tone is cancelled;
step six: and when the detected object is judged to be the electric vehicle, the elevator is kept to be opened for a long time within the preset time until the electric vehicle exits from the elevator car. And if the electric vehicle exits the elevator car within the preset time, the waiting of the preset time is cancelled. In this embodiment, the preset time is 20 seconds.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
