As a driver, the biggest problem of driving in foggy weather is that he cannot make a correct judgment on whether there are obstacles ahead of him on the road, and even Cause safety hazards, affect the speed of travel, and the safety factor is also greatly reduced. Any driver knows that the safest and labor-saving way to drive in fog is to follow the tail lights of the vehicle in front, because the tail lights of the vehicle in front are used as a reference Objects, can make a correct judgment for whether there is an obstacle between the driving front and the reference object, but in foggy days, the visible distance is very small, the visibility of the obstacle is low, and the obstacle is already very close when the obstacle is seen. Collision may occur, so the difficulty of driving in fog is the problem to be studied and solved by the utility model.

如图1所示，是本实用新型一种激光穿雾测距雷达示意图。在图1中，一种激光穿雾测距雷达，包括激光头3、车身1、车自身电源，在车身1前部设有可照射在行驶前方路面激光的激光头3，与车自身电源电连接，所述激光头可以是多个，所述每个激光头与路面的夹角均为可调，所述激光头与地面的夹角设置成可调的方案可以是手动调整，也可以是电动自动调整，本实施例的所述激光头布置为三行四列、通过4个固定支架均布连接在车身1前部，所述车身1前部可以是保险杠，如图1所示，也可以是车身1前盖上方，如图3所示，也可以是驾驶室顶部，所述激光头3与路面呈一定夹角，激光光束照射在路面的光点4距车身距离为安全距离，所述每行激光头3与路面的夹角相同，所述多行的激光头3与路面的夹角由上至下依次由小变大，激光光束照射在路面的光点4距车身距离为由远及近的距离，每行均设置一个开关控制。As shown in Figure 1, it is a schematic diagram of a laser penetrating fog ranging radar of the present invention. In Fig. 1, a kind of laser fog-penetrating ranging radar comprises alaser head 3, avehicle body 1, and a power supply of the vehicle body. Alaser head 3 that can irradiate a laser on the road ahead of the vehicle is arranged at the front of thevehicle body 1, and is connected to the power supply of the vehicle body. connected, the laser head can be multiple, and the angle between each laser head and the road surface is adjustable, and the angle between the laser head and the ground is set to be adjustable. It can be manually adjusted, or it can be Electric automatic adjustment, the laser heads in this embodiment are arranged in three rows and four columns, and are evenly connected to the front part of thevehicle body 1 through 4 fixed brackets. The front part of thevehicle body 1 can be a bumper, as shown in Figure 1. It can also be the top of the front cover of thevehicle body 1, as shown in Figure 3, it can also be the top of the cab, thelaser head 3 is at a certain angle with the road surface, and the distance between thelight spot 4 of the laser beam on the road surface is a safe distance from the vehicle body, The angle between thelaser heads 3 of each row and the road surface is the same, the angles between the multiple rows oflaser heads 3 and the road surface are gradually changed from small to large from top to bottom, and the distance from thelight spot 4 of the laser beam on the road surface to the vehicle body is From far to near distance, each row is set with a switch control.

工作原理：working principle:

将三行四列激光头3设置成与路面的夹角由上至下依次递增的方式排列在车身1前部，最上面一排照射的最远，最下面一排照射的最近，可以调整夹角使激光光束照射在路面的光点4距车身距离由远及近为150米、100米、20米等，根据实际情况即雾天浓雾的大小、能见度的高低调整，并且还可以选择不同的开关来选择不同的安全距离，如果车辆在行进过程中所选择的角度不变，也就是说在车辆行驶前方设置了本车辆与激光光束照射在路面的光点4之间的自定义的安全距离，一旦行进前方接近障碍物2，由于所设定的夹角不变，所以光点4会因为障碍物2的接近和遮挡而不能向地面照射，其光点4照射在障碍物上的水平位置会逐渐提高，如图2和图3所示，这种变化可以提醒司机前方障碍物2距离车身的远近，距离越近则光点水平位置越高，为驾驶车辆的司机做出正确判断提供了有效的依据，增加了雾天行车的安全系数，同时提高了雾天行车的车速，由于激光光束聚集并成角度射向地面，并不是散光光源，所以并不会影响对面行驶来车辆司机的视线。Thelaser heads 3 in three rows and four columns are arranged in the front of thevehicle body 1 in such a way that the angle between them and the road surface increases from top to bottom. The top row irradiates the farthest, and the bottom row irradiates the closest. Angle makes the laser beam irradiate thelight spot 4 on the road surface and the distance from the vehicle body is 150 meters, 100 meters, 20 meters, etc., according to the actual situation, that is, the size of the thick fog in foggy days and the level of visibility, and you can also choose different switch to select different safety distances. If the angle selected by the vehicle remains unchanged during the driving process, that is to say, a self-defined safety distance between the vehicle and thelight spot 4 illuminated by the laser beam on the road is set in front of the vehicle. Once you approach theobstacle 2 in front of you, since the set angle remains unchanged, thelight spot 4 will not be able to illuminate the ground due to the approach and occlusion of theobstacle 2, and the level of thelight spot 4 shining on the obstacle The position will gradually increase, as shown in Figure 2 and Figure 3. This change can remind the driver of the distance between theobstacle 2 in front of the vehicle body. It provides an effective basis, increases the safety factor of driving in fog, and at the same time increases the speed of driving in fog. Since the laser beam is gathered and shot at the ground at an angle, it is not a light source of astigmatism, so it will not affect the safety of drivers driving on the opposite side. line of sight.
