Detailed Description

The utility model is further described below in connection with embodiments. The following embodiments are only for more clearly illustrating the technical aspects of the present utility model, and should not be used to limit the scope of the present utility model.

In the description of the present utility model, unless explicitly stated and limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In the present utility model, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but being in contact with each other through additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are orientation or positional relationships based on those shown in the drawings, merely for convenience of description and simplicity of operation, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the utility model. Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.

The embodiment of the utility model provides an intersection warning device, which is shown in fig. 1 and 2, and comprises a camera 1, a processing unit, a shell 2, a supporting device 3 and a warning device 4. Specifically, the supporting device 3 is disposed at the intersection. The shell 2 is positioned on the supporting device 3 and can be connected with the supporting device by adopting the modes of bolts, clamping, welding and the like. The camera 1 is located above the shell 2, and is connected with the shell 2, and an output interface of the camera 1 is connected with an input interface of the processing unit through a USB line. The processing unit is located inside the housing 2 and processes the image captured by the camera 1. The alarm 4 is connected with the outer surface of the shell 2 or the supporting device 3, and an input interface of the alarm 4 is connected with an output interface of the processing unit through a USB line.

The intersection warning device provided by the utility model is arranged in places such as T-shaped intersections, which have a wide visual field. The camera 1 is used for shooting images at intersections and sending the images to the processing unit through the data line. After the processing unit recognizes the pedestrian information in the image, a signal is sent to the warning indicator 4, and the warning indicator 4 gives an early warning to vehicles and pedestrians around the intersection, so that traffic accidents caused by the fact that the view is blocked are avoided.

The shell 2 is used for supporting the camera 1 and the alarm 4. A mounting bracket for supporting the camera head 1 may be mounted on the upper surface of the housing 2 by bolts, and the camera head 2 may be mounted on the housing. The housing 2 is also used for protecting an internal processing unit, and a bracket is arranged in the housing for installing the processing unit, and is connected with the housing 2 through bolts. The shell 2 is provided with a through line hole, so that the camera 1 is conveniently connected with the processing unit and the processing unit is conveniently connected with the alarm 4.

Specifically, the processing unit is raspberry group 3B. The raspberry group 3B is provided with a deep convolutional neural network algorithm, so that pedestrian detection and alarm can be realized.

In the preferred embodiment of the utility model, the shell is an insulating shell, and the side of the shell facing the intersection is provided with a national standard 80cm wide-angle lens. The wide angle lens can be used as an aid to provide information to the vehicle driver along with the alarm 4.

Specifically, the supporting device is a stand column with the height of 2-3m, and is connected with the ground through expansion screws. The height of 2-3m can ensure the good visual field of the camera, and can realize good acquisition work.

Specifically, the model of the camera is YH-AJSM08, and can acquire image information within 180 degrees, so that the use requirement of an intersection is met.

Specifically, the alarm is COB self-adhesion lamp area, and the alarm twines on the surface of casing. When the processing unit detects pedestrians, the warning device lights to remind the vehicle of paying attention to the pedestrians, and when the processing unit does not detect the pedestrians, the warning device is turned off.

In an alternative embodiment of the utility model, the intersection warning device further comprises a power supply; the power supply is positioned in the shell 2 and supplies power to the camera 1, the processing unit and the alarm 4. The power supply can use JTD60 to provide 12V power to the alarm 4, the processing unit and the camera 2.

Referring to fig. 2, the supporting device 3 is arranged at the corner of the T-junction; the camera 1 is opposite to the auxiliary road 7 of the T-shaped intersection and opposite to the right angle alpha, so that the camera can acquire information of the coming direction of vehicles on the auxiliary road 7 and the main road 6, and meanwhile, the wide angle lens faces the vehicles to come direction, so that a driver can observe the condition of the intersection conveniently.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present utility model, and such modifications and variations should also be regarded as being within the scope of the utility model.
