As shown in fig. 2, the system structure of the intelligent lamp pole mainly includes: the system comprises modules such as audio and video equipment, camera equipment, lighting equipment, a logic control unit, a setting unit and a storage unit.
Audio-video devices are used to provide audio-video services, such as: providing instant video, alarm function for vehicles and pedestrians.
The camera equipment is used for carrying out video monitoring and recording the traffic condition near the lamp post.
The setting unit is used for presetting parameters, such as the speed of the vehicle, whether barrier shielding exists or not, and the like. The storage unit is used for storing necessary data information of the system.
The logic control unit provides various services for calculation and decision-making, triggering alarm actions (such as field ringing or video emergency prompts), and transmitting information to the background monitoring center. The communication module is used for transmitting the number information of the lamp post to an adjacent lamp post or a background.
In the embodiment of the application, the video monitoring function of the intelligent lamp pole is mainly utilized.
Be provided with the camera on first intelligent lamp pole for the traffic information of control covered area. The first object is a moving object, such as a vehicle or a pedestrian, within the coverage area. Of course, the first object may also be an obstacle.
The first object may include at least one. The first traffic information of the first object may be information such as a moving speed, a moving direction, and a distance from an intersection.
In a feasible implementation mode, the first intelligent lamp pole collects monitoring videos in real time through the camera and caches the monitoring videos, and then analyzes the monitoring videos to generate first traffic information of the first object.
S102, second traffic information of a second object acquired by a second intelligent lamp pole is acquired, the distance between the first intelligent lamp pole and the second intelligent lamp pole is within a preset distance range, and the second intelligent lamp pole comprises at least one lamp pole;

Fig. 6 is a schematic flow chart of a traffic accident warning method according to an embodiment of the present disclosure. The traffic accident early warning method can comprise the following steps:
s201, acquiring first traffic information of a first object acquired by a first intelligent lamp pole, wherein the first traffic information comprises a first moving speed and a first position;
see S101 for details, which are not described herein again.
S202, judging whether the first moving speed is greater than or equal to a speed threshold value;
the speed threshold comprises a driving speed threshold or a pedestrian movement speed threshold.
And when the moving object is a vehicle, the speed threshold is a driving speed threshold. The speed threshold can be understood as the highest value of the safe driving speed, and beyond the threshold, the driving risk exists.
When the moving object is a pedestrian, the speed threshold is a pedestrian speed threshold. The speed threshold is understood to be the highest value of the safe walking speed, and if the speed threshold is exceeded, the brake may be in short time to cause traffic accidents.
S203, if so, acquiring second traffic information of a second object acquired by a second intelligent lamp pole, wherein the distance between the first intelligent lamp pole and the second intelligent lamp pole is within a preset distance range, the second intelligent lamp pole comprises at least one, and the second traffic information comprises a second moving speed and a second position;
when the first moving speed is greater than or equal to the speed threshold, it is indicated that the first object is fast in moving speed, sometimes the brake is too late, and a traffic accident may occur, so that it is necessary to judge whether other moving objects or obstacles exist in the moving direction, and further acquire second traffic information acquired by the second intelligent lamp pole in the moving direction.
The first intelligent lamp pole acquires the second traffic information of the second object acquired by the second intelligent lamp pole, which may be referred to as S102 specifically, and details are not described here.
S204, calculating a first distance between the first position and a destination, and calculating a first time for the first object to reach the destination based on the first moving speed and the first distance;
the destination may be understood as the intersection of the first object with the second object in the respective direction of movement.
For example, as shown in fig. 7, a first smart light pole a collects traffic information of a first object (a running vehicle), a second smart light pole B collects movement information of a second object (a suddenly appearing pedestrian), and the movement of the vehicle and the pedestrian is crossed with S, which is the destination.
Since a pedestrian is stopped by a vehicle parked on the roadside during the movement, the vehicle cannot see the pedestrian clearly, and when the moving speed of the vehicle is high, there is a high possibility that the pedestrian collides with the vehicle.
A first distance S1 between the first position of the vehicle and S is calculated, then the first time T1 for the vehicle to reach S is S1/V1.
S205, calculating a second distance between the second position and the destination, and calculating a second time when the second object reaches the destination based on the second moving speed and the second distance;
a first distance S2 between the second position of the pedestrian and S is calculated, and a second time T2 for the pedestrian to reach S is S2/V2.
S206, pre-judging whether traffic accidents can happen to the first object and the second object based on the first time and the second time;
if T1 is equal to T2, it indicates that the time of the vehicle and the pedestrian passing the point S is the same, and it is predicted that the first object and the second object can have a traffic accident. If T1 is not equal to T2, it indicates that the time for the vehicle and the pedestrian to pass the S point is different, and it is predicted that no traffic accident occurs between the first object and the second object.
S207, if the first time is equal to a second time, generating a video containing the first traffic information and the second traffic information;
when the traffic accident is predicted to happen, a dynamic effect graph from the current position to the collision of the first object and the second object is generated.
For example, a video including a plurality of frame images as shown in fig. 8 is generated, showing a dynamic effect of a collision of a vehicle with a pedestrian.
S208, displaying the video on the first intelligent lamp pole, and sending the video to the second intelligent lamp pole for displaying.
And the first intelligent lamp pole and the second intelligent lamp pole are respectively provided with a display screen. The video is displayed on the first intelligent lamp pole and the second intelligent lamp pole respectively, so that the first object and the second object can be adjusted conveniently in time after the video is watched. Provides visual field for both traffic accident parties in advance to avoid accidents.
Optionally, the first intelligent lamp post sends the video to the first object and the second object respectively, and sends an alarm prompt to the first object and the second object in an audio mode, so that the first object and/or the second object can be adjusted in time when the video displayed on the intelligent lamp post is not viewed, and traffic accidents are avoided.
S209, the first traffic information and the second traffic information are sent to a command center for recording.
In the embodiment of the application, a first intelligent lamp pole acquires first traffic information of a first object acquired by the first intelligent lamp pole, when the first object is determined to move at a speed greater than a speed threshold value, second traffic information of a second object acquired by a second intelligent lamp pole close to the first intelligent lamp pole is acquired, whether a traffic accident occurs between the first object and the second object is judged in advance based on the first traffic information and the second traffic information, and when the traffic accident occurs, early warning information is displayed to the first object and the second object through a display screen of the intelligent lamp pole respectively. The coverage of every intelligent lamp pole is limited, through the interaction and the calculation of a plurality of intelligent lamp poles, can accurately predict the traffic accident that will take place and carry out the early warning, utilizes intelligent lamp pole screen, and driver and pedestrian can both see the rear field of vision of barrier, and then can avoid the emergence of traffic accident, have improved the security of driving safety nature and personal property.
