The appearance of the device of the utility model is a cake-shaped structure, and the cake surface of the cake-shaped structure is respectively embedded with six characters of "事", "Gu", "Yi", "Fa", "Di" and "Duan" composed of red LED indicator lights or other characters. Warning slogans, such as "Danger", "Slow down", etc.; the LED indicator light is embedded in the cake surface, and the surface is coated with yellow reflective material; the solar panel is wrapped around the periphery of the cake-shaped structure; inside the structure. The whole inventive device is small and exquisite in size, compact in structure and simple and convenient to install.

The utility model adopts a microprocessor to realize the control of the whole machine, and the microprocessor can send out a PWM signal, and has the functions of timing start, power management, LED flicker frequency management and the like. Among them, the LED can be set to different colors according to different road danger levels, which is more convenient to remind drivers to pay attention to road conditions.

The beneficial effects of the utility model are: the combination of solar panels and storage batteries is used as a power supply, no traditional energy is needed for power supply, and a low-power LED lamp is used as a light source, which is green and environmentally friendly, energy-saving, suitable for roads of various grades, and easy to use. Promotion, and not affected by the weather, can ensure that drivers can be clearly warned in any weather conditions, effectively prevent traffic accidents, and reduce the loss of people's lives and property.

Detailed ways

As shown in Figure 4, the utility model device includes a solar cell panel, the solar cell panel is the energy supply unit of the utility model whole device, the solar cell panel absorbs solar energy during the day, and converts the solar energy into electric energy and stores it in the storage battery, at night, The stored electric energy of the storage battery supplies power to the microprocessor, the LED driver chip and the LED indicator light. The output terminal of the microprocessor is connected with the input terminal of the LED driver chip, and the output terminal of the LED driver chip is connected with the input terminal of the LED indicator light.

The single-chip microcomputer used in the microprocessor uses a chip with PWM pulse width modulation function as the micro-control chip of the whole machine. The single-chip microcomputer provides a PWM signal to the LED driver chip, and drives the low-power LED indicator light through the LED driver chip. The single-chip microcomputer sends out a PWM signal with a changing duty cycle, so that the LED indicator light emits discrete pulsed light, and in this way reminds the passing vehicles to pay attention to slow down.

As shown in Fig. 2 and Fig. 3, the appearance structure of the device in this embodiment is a round cake-shaped structure, and the cake surface 2 is embedded with red LED indicator lights respectively. A word, the LED indicator light 1 is embedded among each cake surface, and the reflective material is coated on the surface, to enhance the light-gathering and reflective effect. In a preferred manner, the diameter of the circle is 15 centimeters, and the characters are small but clearly legible. The solar cell panel 3 is wrapped around the periphery of the round cake, and the storage battery 4 is arranged inside it to facilitate storage of the energy converted by the solar cell. It has been working continuously to remind passing vehicles to pay attention to complex road conditions, and the warning effect is obvious, and it is not affected by the weather.

As shown in Figure 1, the four devices designed as "front", "square", "sharp" and "bend" respectively will be placed at the intersection guardrails at appropriate intervals before accident-prone areas such as curves, close to the road in the direction of vehicle travel, and have important warning.

Applying reflective material on the surface of the round cake-shaped main body logo can make the headlights of the car guide through the reflected light when it is irradiated at a long distance, so as to ensure that the device can effectively play a warning role no matter day or night.

The solar panel is placed around the periphery of the device as a patch, with a width of two centimeters, and the converted power can maintain the normal use of the utility model at night.

The device of the utility model can be stable and reliable, safely and effectively warn road conditions in accident-prone areas, save energy, and is suitable for popularization.

The utility model adopts a microprocessor to realize the control of the whole machine, and the microprocessor can send out a PWM signal, and has functions such as timing start, power supply management, LED indicator light flashing frequency management and the like. Among them, the LED indicator light can be set to different colors according to different road danger levels, which is more convenient to remind drivers to pay attention to road conditions.
