[0027] In order to better explain the present invention and facilitate understanding, the following Figure 1-2 , the utility model is described in detail through specific implementation methods.

[0028] Embodiment 1:

[0029] Reference Figure 1 and Figure 2 The embodiment of the utility model provides a highway vehicle safety detection system, including a cloud, an identification unit and an indication unit, wherein the identification unit and the indication unit are both connected to the cloud in communication; the identification unit includes a driver detection device and a congestion detection device, and the indication unit includes a projection device and a speaker both mounted on the highway; when the driver detection device detects that the driver is driving fatigued, the speaker outputs a warning sound; when the congestion detection device detects that a certain road is congested, the projection device projects diversion information on the highway. The highway includes a plurality of roads, and the projection device is set correspondingly to each of the roads.

[0030] In this embodiment, the highway vehicle safety detection system can detect whether the driver is in a fatigued driving state and issue a warning sound to remind the driver; it can also project diversion information through projection equipment when the road is congested, play a role in diverting traffic, and thus reduce the accident rate of road traffic vehicles to a certain extent and improve vehicle traffic efficiency.

[0031] Specifically, the warning sound output by the speaker may be a whistle sound, and the diversion information may be a road diversion line and a speed reduction diversion line.

[0032] The projection device comprises a guide line projection module and a deceleration line projection module. The guide line projection module can project a lane change guide line, and the deceleration line projection module can project a speed reduction guide line.

[0033] The road guide lines are inclined, the speed reduction and diversion lines can be double lines arranged along the width of the road, and the projection of the diversion information can be set to a striking color, such as yellow or red.

[0034] Furthermore, considering the display issues of projection under strong light conditions, the projection equipment can be set to work only at night.

[0035] The driver detection device includes a first vehicle identification module; when the vehicle identification module detects that the driving speed of multiple adjacent vehicles is zero, the cloud outputs a congestion judgment so that the projection device projects diversion information on the highway to divert the vehicles to a smooth road.

[0036] In this embodiment, congestion is determined based on the speed of adjacent vehicles. For example, when there is no traffic light on the road and the speed of multiple adjacent vehicles is zero, there is a great possibility of an accident. At this time, the cloud outputs the judgment of road congestion. At this time, the projection device outputs the diversion information on the road to divert vehicles to non-congested roads in advance to improve the traffic efficiency of vehicles.

[0037] The congestion detection devices all include a second vehicle identification module; when the vehicle identification module detects that a vehicle's driving trajectory is deviated, the cloud outputs a fatigue driving judgment, so that the speaker outputs a warning sound.

[0038] In this embodiment, the second vehicle identification module can detect the vehicle's driving deviation. When the vehicle's driving trajectory gradually deviates from the highway guide line, the driver is likely to be driving fatigued. At this time, the cloud controls the speaker to output a warning sound to remind the driver to concentrate on driving. The first vehicle identification module and the second vehicle identification module are both visual cameras.

[0039] Specifically, the road can be a highway, and the identification unit and the indication unit can be arranged on a gantry on the road.

[0040] Embodiment 2:

[0041] Reference Figure 1-2 In addition to all the technical solutions of the above embodiments, the embodiments of the present utility model further have the following technical solutions:

[0042] The identification unit also includes a temperature detection module and a humidity detection module to detect the temperature and humidity of the road environment, so that the cloud can output a determination of the slippery condition of the road.

[0043] Road icing or frost is affected by road humidity and temperature, especially in the current era of ethanol gasoline. Ethanol gasoline produces more water after combustion. For most vehicles with hidden exhaust, this water will directly act on the road. In high-altitude cold areas, a thin layer of ice will adhere to the road surface, affecting the adhesion of the vehicle tires, thereby reducing the vehicle's braking performance, making it more likely to cause rear-end collisions. Therefore, by setting up a temperature detection module and a humidity detection module, the actual temperature and humidity values ​​of the road environment can be measured, and the possible probability of road icing can be inferred. Specifically, based on laboratory data simulation, the recommended speed and following distance under the corresponding temperature and humidity can be obtained, which will not be elaborated here.

[0044] The projection device also includes a following distance projection module to project a recommended vehicle distance on the road; the indication unit also includes a display screen that is connected to the cloud for communication and is set up on the road to output a recommended travel speed.

Moreover, when a first feature is “above”, “above” or “above” a second feature, it may be that the first feature is directly above or obliquely above the second feature, or it may simply mean that the first feature is higher in level than the second feature.
