and the indication intensity adjusting module 6, the humidity detection module 5 and the traffic indication module 2 are used for acquiring humidity information and adjusting the projection intensity of the traffic indication module 2 according to the humidity information.
The real-time road condition information in the big data traffic system is directly acquired through the big data access end 1, the road condition is provided in real time, and the real-time road condition is transmitted to each traffic indication module 2 through the control center 4. Wherein the traffic indication module 2 of each position is connected through thing networking module 3, makes it carry out data interaction each other, and not carry out data interaction through networking module connection to unified server, this interactive mode is only each traffic indication module 2 independent operation, carries out data interaction with the server alone, can increase the work load of server this moment, and then influences data interaction's efficiency. Through letting utilize thing networking module 3 to carry out interconnect between each traffic indication module 2, can make full use of network resource, let data transmission can transmit each other, let data transmission can carry out the distributed transmission, but the centralized processing, can improve transmission speed greatly. The humidity detection module 5 can acquire the actual environment where the current traffic indication module 2 is located in real time, and then adjust the work according to the actual environment, and the adjustment effect of the indication intensity adjustment module 6 is combined, so that the projection intensity can be adjusted corresponding to different actual environments.
Specifically, the platform further comprises a positioning module 7 for acquiring position information, the big data access end 1 is further connected to a meteorological data center and acquires current meteorological data according to the position information, the indication intensity adjusting module 6 determines whether the platform is in a rainy state or a foggy state or a cloudy and sunny state after comparing the humidity information with the meteorological information, and when the platform is in the rainy state, the indication intensity adjusting module 6 increases the projection brightness of the traffic projection component 21; when the fog state is reached, the intensity adjusting module 6 is instructed to change the projection component 21 into flash projection; when the projection module is in a cloudy or sunny state, the indication intensity adjusting module 6 adjusts the projection component 21 to default projection intensity; when at night, the intensity adjustment module 6 is instructed to adjust the projection assembly 21 to a reduced brightness power saving mode.

The intensity adjustment module 6 is instructed to make different adjustments to the projection assembly 21 for different actual circumstances. When raining, because the rainwater can obscure the field of vision, especially after the preceding wind shield of vehicle has water, the light that can let the driver see produces the distortion, and unified mistake deems as lights such as tail lamp of front truck, if illumination intensity is lower this moment, can lead to the display effect poor, improves behind the luminance, can improve the conspicuous degree, lets the driver notice the projection information on ground more easily. Under the condition of hazing, because the fog in the air is mainly for the aerosol, can influence the penetrating effect of light this moment, through changing the mode with direct projection into scintillation projection, improve the effect of attracting the eyeball through the scintillation, let the scintillation effect of producing light in the fog, change the mode that projects ground into the mode of scintillation in the fog, and then overcome the poor condition of light penetrating effect under the hazing condition. On cloudy or sunny days, the projection module 21 may default to a normal projection mode, with normal projection intensity. At night, the projection intensity can be weakened due to the obvious effect of the light at night, and the energy consumption at night is further saved.

Of course, the light intensity sensing component 8 may also be in communication with the indication intensity adjustment module 6.
The light intensity sensing module 8 can form feedback with the projection module 21, so that the projection module 21 can accurately distinguish whether the illumination is night and whether the projection intensity matches the current illumination intensity. The design of the coating layer 222 can protect the light intensity sensing assembly 8 and also prevent the primer layer 221 from being worn by sand and wheels.
In an optimized embodiment, the fluorescent flakes 223 for reflecting light rays are uniformly mixed in the coating layer 222.
The projected light can be transmitted in all directions by the fluorescent paillette 223, and can be directly projected to the sight of the user. Moreover, the situation that the light in the rain is not distorted clearly can be overcome, the display effect can be improved, and the light can generate the diffuse reflection effect.
Preferably, the projection module 21 includes a fixing module 211, a controller, a projector 212 for projection, a fine-tuning module 213 for fine-tuning the angle of the projector 212, and a detecting module 214 for real-time monitoring the posture of the projector 212; the controller receives real-time road condition information and controls the projector 212 to project images with corresponding colors; the detection component 214 is connected with both the controller and the projector 212 to acquire the real-time posture of the projector 212 and send the real-time posture to the controller; the fine tuning component 213 is connected to a controller, which controls the fine tuning component 213 to adjust the pose of the projector 212 according to the real-time pose of the projector 212.
Can support fixedly at the roadside of lane both sides through fixed subassembly 211, the projector 212 is installed and can be conveniently carried out the projection on fixed subassembly 211 more, because the vibrations that wind blows and the vehicle was driven, can lead to the gesture of projector 212 to produce the change, this moment because the projection distance is longer, if have certain deviation, can let the deviation grow under the enlargements of this distance, gesture through detecting component 214 real time monitoring projector 212, and then feed back to the controller, when the gesture produces the change, controller control fine setting subassembly 213 finely tunes the gesture of projector 212. Wherein the detection component 214 may employ a six-axis acceleration sensor or a nine-axis acceleration sensor. By the structure, the projection position of the projector 212 can be adjusted in real time, so that the projector is always in the accurate projection position, and the prompt effect is further ensured.
In order to ensure the fine adjustment effect of the fine adjustment assembly 213 during fine adjustment and the wind-resistant and shock-resistant effect of the projector 212, and avoid the angular deviation of the projector 212 under wind blowing and shock, the present solution further provides a fine adjustment assembly 213 which has a simple structure and is convenient to implement. The fine adjustment assembly 213 comprises a driving assembly 2131 and a positioning assembly 2132 for positioning the driving assembly 2131, the driving assembly 2131 is connected with a controller, and the controller controls the driving assembly 2131 to drive the projector 212 to perform fine adjustment on the posture; the driving assembly 2131 comprises a motor, a worm wheel 21311 and a worm 21312; the worm wheel 21311 is matched with the worm 21312, and the motor is linked with the worm 21312; a rotating shaft 21313 is coaxially fixed on the worm wheel 21311, and the rotating shaft 21313 is positioned by the positioning assembly 2132 and is linked with the projector 212 to drive the projector 212 to finely adjust the posture.
