Road bearing warning device and road bearing warning method thereof
The invention provides a road bearing warning device which comprises a display unit and a power supply unit, the power supply unit is electrically connected with the display unit, and the power supply unit is used for providing different voltages for the display unit according to the weight of a heavy object borne by a road; the display unit comprises a red organic electroluminescent element and a green organic electroluminescent element; the display unit is used for displaying a first color when the weight of the heavy object is greater than a road bearing threshold; a second color is displayed when the weight of the heavy object is smaller than the road bearing threshold value; and a third color is displayed when the weight of the weight approaches the road bearing threshold. According to the road load-bearing warning device, based on different brightness-voltage characteristics of the red organic electroluminescent element and the green organic electroluminescent element, when heavy objects with different weights pass through the road load-bearing warning device, different voltages are provided for the display unit; and the voltage at the two ends of the display unit is controlled to realize the switching of red light, yellow light and green light warning signals, so that the current warning lamp display system is optimized.
本发明提供一种道路承重示警装置，包括显示单元和供电单元，供电单元与显示单元电连接，供电单元用于根据道路承载重物的重量为显示单元提供不同的电压；显示单元包括红色有机电致发光元件和绿色有机电致发光元件；显示单元用于在重物的重量大于道路承重阈值时显示第一颜色；在重物的重量小于道路承重阈值时显示第二颜色；在重物的重量接近道路承重阈值时显示第三颜色。该道路承重示警装置，基于红色有机电致发光元件和绿色有机电致发光元件不同的亮度‑电压特性，通过使不同重量的重物通过该道路承重示警装置时，为显示单元提供不同的电压，控制显示单元两端的电压使其实现红光、黄光、绿光示警信号的切换，优化了目前的示警灯显示系统。
