The pedestrian gets into the pedestrian crosswalk through bracing piece 1 below on, this process AI camera 102 detects the pedestrian and sends out the signal to control terminal 101, control terminal 101 sends out the signal to first warning light 103 after receiving the signal, send the yellow light on the first warning light 103, and carry out the scintillation of certain frequency, remind the driver to walk slowly, if the speed measuring camera 2 detects the vehicle speed of going on the lane too high this moment, and the speed of a motor vehicle does not have obvious reduction, speed measuring camera 2 sends out the signal to control terminal 101, make control terminal 101 start two driving motor 207 and rotate relatively, two driving motor 207 drive two eccentric shafts 206 rotate, two eccentric shafts 206 rotate extrusion carriage 204 rebound, carriage 204 shifts up and extrudes two rotor plate 203 swing archs, simulation deceleration strip effect.
The two eccentric shafts 206 rotate to release the extrusion on the two arc-shaped fixed plates 306, and are acted by the second springs 305, the two sliding blocks 304 drive the two sliding plates 301 to be close together through the two arc-shaped fixed plates 306, and are simultaneously acted by the first springs 302, the two sliding plates 301 and the ratchets 3 are tightly matched, the principle is similar to that of a ratchet pawl, namely, after the sliding plates 301 and the ratchets 3 are matched, the sliding plates 301 can only move upwards under the action of the first springs 302, at the moment, the sliding frames 204 move upwards to drive the two sliding plates 301 to move upwards, the driving motors 207 stop working after working for a specified angle, and at the moment, under the matching action of the sliding plates 301 and the ratchets 3, the two rotating plates 203 swing convexly and keep the state after swinging.
When a subsequent vehicle passes through the rotating plate 203, the vehicle vibrates to focus the attention of a driver on the vehicle, so that the driver can observe pedestrians on a pedestrian crossing to timely perform deceleration parking operation, meanwhile, when the vehicle passes through the rotating plate 203, the vehicle presses the rotating plate 203, the rotating plate 203 moves downwards to deform rubber of the sliding frame 204, the pressure sensor 4 is extruded by the rotating plate 203 at the moment, the pressure sensor 4 sends a signal to the control terminal 101, the control terminal 101 which receives the signal starts the second warning lamp 401 and the LED monochromatic display screen 402, the second warning lamp 401 flashes red light, characters such as attention vehicles and the like are flashed on the LED monochromatic display screen 402, an audio system of the LED monochromatic display screen 402 sends out broadcasting of the attention vehicles, and when the AI camera 102 on the other side detects that the last person on the pedestrian crossing walks out, namely, no pedestrian crossing exists, the control terminal 101 starts the parts to reversely work, so that the parts are restored to the initial state.
After entering night, the light-sensitive sensor 501 detects the weakening of light, the infrared camera 504, the first servo motor 602 and the second servo motor 7 are communicated with the control terminal 101, at the moment, when a pedestrian enters the pedestrian crossing through the AI camera 102, the AI camera 102 identifies the moving direction of the pedestrian, the corresponding first servo motor 602 is started simultaneously, the second baffle 601 is moved, the shielding of a corresponding arrow hole on the first baffle 6 is removed, then when the pedestrian moves to a specified area, the corresponding infrared camera 504 detects the movement of the pedestrian, the infrared camera 504 sends a signal to the control terminal 101, and the control terminal 101 which receives the signal starts the corresponding illuminating lamp 502 and the second servo motor 7.
Light 502 work sends yellow light, yellow light shines on partial pedestrian's crosswalk through the space between first baffle 6 and lamp shade 503, the pedestrian is arranged in annular light, be convenient for the driver to observe pedestrian's position, so that the driver makes operations such as the parking of slowing down, yellow light makes the subaerial arrow point that has pedestrian direction of motion of throwing simultaneously through the arrow point hole on first baffle 6 simultaneously, and second servo motor 7 work drives two second sliding plates 301 through two straight-toothed gear 701 and carries out corresponding rotation, the arrow point shape light of making pedestrian's crosswalk both sides throw, carry out the scintillation of certain frequency, produce the effect of similar horse race lamp, make the driver change and know pedestrian's direction of motion on the pedestrian crosswalk.
Example 3
On the basis of embodiment 2, when two lanes middle parts were planted when great vegetation, received the effect of sheltering from of vegetation, and visibility was low night, whether there was the pedestrian on influencing the driver and observing the pedestrian crosswalk on the opposite direction lane, and AI camera 102 detects the pedestrian and is located the pedestrian and moves on the crosswalk, will take place above-mentioned work with the same principle, make two rotor plates 203 swing arch, when driver's driving vehicle passes through the arch of rotor plates 203 afterwards, the vehicle takes place vibrations, make driver's attention improve, remind the driver to slow down to travel simultaneously, steadily stop before the crosswalk.
And when the driver drives in the environment with poor visibility, the parts work in the same way to remind the driver of driving the vehicle by vibration, so that the attention of the driver is improved, the vehicle is decelerated, and traffic accidents are avoided.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
