Low grade highway curve blind area display and alarm device

Abstract

The invention discloses a low grade highway curve blind area display and alarm device comprising a first geomagnetic sensor, a first outdoor infrared microwave detector, a first storage battery, a first supporting rod, a first ZigBee router, a first control circuit board, a first metal aluminum box, a first LED display screen, a first solar cell panel, a first ZigBee terminal node, a first LED display board, a second geomagnetic sensor, a second outdoor infrared microwave detector, a second storage battery, a second supporting rod, a second ZigBee router, a second control circuit board, a second metal aluminum box, a second LED display screen, a second solar cell panel, a second ZigBee terminal node and a second LED display board. The driver entering the curve entrance is enabled to know the road condition information of the entrance of the other side of the curve in advance, and the driver of one side entrance of the curve can also be notified of the information of the entered curve in advance so that the driver can be prompted to pay attention to driving safety when driving around the curve.

Description

technical field [0001] The invention relates to automatic detection and alarm equipment, in particular to a display and alarm device for low-grade road curve blind spots. Background technique [0002] When a car passes through a curve with low visibility, the light is easily scattered and the driver is prone to fatigue. If the U-shaped curve is sharp and the sharp curve ahead cannot be identified in time, traffic accidents are likely to occur. When a car passes through a curve with a blind spot, it is difficult for the driver to see the cars and people on the other side of the curve. When he sees the situation on the other side, it is too late, which often leads to traffic accidents. In addition, when the visibility is low and the road is wet and slippery In this case, the danger of driving in blind spots on curves is increased. [0003] In the prior art, a convex reflector is installed in the blind spot of the curve to remind drivers and pedestrians on the other side of th...

Problems solved by technology

But these methods all have very big defect, namely: 1. the reflective figure surface of convex reflector is little, just can't see clearly at a little distance, is easily affected by sunlight, haze weather and rain and snow, and for night doesn't work at all

2. This device can only detect whether there are vehicles or objects with iron blocks on the other side of the curve, but cannot detect whether there are people or other animals on the other side of the curve.

3. The paint is easily affected by the weather. In the case of extremely low visibility, the lights of the car are easily scattered, and the light that hits the paint is not easy to reflect back, and the driver cannot observe well whether there is a curve ahead
