Description
Technical Field
The utility model relates to an elevator control technical field more specifically says, is a prevent that electric bicycle from advancing elevator management and control system.
Background
In recent years, disaster occurrence caused by charging of electric bicycles occurs, and most of the disaster occurrence is caused by that users in high-rise residences push electric bicycles to home to charge the electric bicycles through elevators. The battery of the electric bicycle is overcharged, the circuit is aged and damaged, the aging internal resistance of the battery is increased, and the like, so that the fire disaster is easily caused. The electric vehicle of the high-rise residence causes fire, the stairwell has siphon effect, open fire can rapidly flow upwards in a short time, a large amount of toxic gas generated by combustion can rapidly permeate the corresponding stairwell, the escape time for high-rise residents is very short, and the problem that the electric vehicle goes upstairs is urgently solved.
The existing elevator is not matched with products which can accurately recognize that an electric bicycle enters the elevator to control the elevator to stop running and allow non-electric bicycles such as wheelchairs and baby strollers to normally use the elevator.
In addition, when devices for preventing electric vehicles from entering are additionally arranged in the existing elevator, the engineering is complex, more problems exist, and some devices or schemes which are commonly used are as follows:
1. adopting a geomagnetic induction scheme: by embedding the induction coil or the geomagnetic sensor in the elevator door, the magnetic flux of the coil loop or the weak magnetic field of the geomagnetic sensor can be changed when a metal object passes through the elevator door from the top, so that the existence of the metal object can be sensed.
The defects are that: this solution does not allow to distinguish all relatively large metal objects such as wheelchairs, baby strollers, electric bicycles, etc. Therefore, in application, a large amount of metal materials are often judged as the electric bicycle by mistake.
2. Adopting an infrared light curtain scheme: when passing through the infrared light curtain, the object can shield the receiving circuit so as to judge the length and height of the object.
The defects are that: the simple judgment of whether the electric bicycle is the electric bicycle or not according to the length and the height of the object is also very unscientific, and a plurality of objects entering the elevator, such as baby strollers, can not be distinguished and identified from the electric bicycle.
3. Adopting an image identification mode: the top of the elevator car is provided with a camera facing the elevator car door.
The defects are that: and when the electric vehicle enters the elevator door, carrying out image detection. The front face position of the electric vehicle is detected for identification. The angle of image recognition is as close as possible to the requirement of an algorithm model, and the angle is very complicated during installation and debugging of the camera; meanwhile, after the electric bicycle completely enters the elevator, if the electric bicycle enters the elevator by riding a bicycle due to the problem of angle, the camera cannot overlook relatively many object feature points of the electric bicycle. The electric vehicle is difficult to recognize in real time after entering, and the human cart can be recognized once again when moving out of the elevator, so that the stop operation time of the elevator cannot be accurately controlled.

Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Referring to fig. 1 to 3, the electric bicycle elevator control system of the present application includes a camera 1, a fixing box 2, an image recognition processing circuit, and the like. The camera 1 is arranged in the fixing box 2, and the camera 1 is fixed on the side wall of the elevator car near the elevator door and near the elevator door at a special inclination angle through the fixing box 2, as shown in fig. 3. The camera 1 can shoot the elevator door to the elevator from the camera 1, so that the camera 1 can acquire the tail image of the car body entering the elevator 3.
As shown in fig. 2 and 4, the fixing case 2 includes a case 28, a bottom edge 29, and a fixing edge 21. The shell 28 is provided with a built-in port 22, a data interface 23 and an infrared remote control receiving window 24. The bottom edge 29 is provided with a mounting plate 210, the mounting plate 210 and the built-in opening form an inclined angle, the inclined angle is 20-50 degrees, the camera is fixed on the mounting plate 210 and is positioned in the shell, so that when the head of the camera is embedded into the built-in opening, the camera shoots the elevator from the elevator door to the inside, and the camera acquires images of the tail part of the car body and the middle and rear parts of the car body entering the elevator. The installation angle is fixed, and the problem of time-consuming debugging during installation is avoided. The fixed edges 21 are connected to two sides of the bottom edge 29, and the fixed box is fixed on the side wall of the elevator car near the elevator door through a connecting piece. The built-in port 22 is provided on a lower bottom edge 25 of the fixing box 2. The data interface 23 and the infrared remote control receiving window 24 are arranged on the side 26 of the fixed box 2. The data interface 23 may be an RJ45 or USB interface.
An image recognition processing circuit is arranged in the fixed box 2. The image recognition processing circuit is connected with the camera to acquire the car tail and part of the car pictures shot by the camera and perform image recognition processing on the car tail and part of the car pictures. When the image recognition processing circuit recognizes that the tail part of the car body and part of the car body pictures are of the electric bicycle, the image recognition processing circuit controls a door opening button or a light curtain of the elevator through a control line, and the door opening button or the light curtain (a light curtain wiring terminal) of the elevator realizes the operation of forbidding closing the elevator door and stopping the elevator from ascending.
In addition, a voice alarm device can be arranged in the fixed box 2. When the elevator realizes that the closing of the elevator door is forbidden and the elevator stops ascending, the voice alarm device prompts residents to move the electric bicycle out of the elevator. In addition, the remote control can be realized through an infrared remote control instruction processing unit connected with the image recognition circuit.
Be different from prior art through at the elevator interior angle installation camera and obtain the picture of automobile body head, this application mainly is with the built-in camera of slope of fixed box, obtains the picture that gets into automobile body afterbody and partial automobile body in the elevator through the camera. The special inclination angle can through the fixed normal installation in the support, has avoided the problem that needs angle regulation among the prior art, simple to operate is swift. The way of obtaining the picture by the tail is more accurate.
The above-described embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention.
