solar road stud truck national standard cast aluminum led
The intelligent wireless road stud can receive the wireless signal given out by the controllers and work through the signal. There is no wire between the road studs, which is much more convenient for installation. However, the sending and receiving of wireless signal are a difficulty.
With the development and mature or the technology of road stud producing, there must be more kinds of road studs are made for clients to choose.
Solar panel: The solar panel can absorb solar energy and transform it into electric energy, and this can be the first link of the whole working system of the solar road stud. The efficiency of the solar panel determines the efficiency of the solar road stud. The single crystal silicon solar panel is widely used nowadays, for it has high photoelectric conversion efficiency, which can be about 14%, to ensure the energy providing when the solar road stud is working. In addition, the solar panel must be high hardness and wear-resisting. For the solar road stud will resist crash and shock everyday, if it is not hard enough, the solar panel will be destroyed and influence the conversion efficiency of the solar panel.
The rated capacity of the battery should meet the needs of 72 hours’ illuminating, if the battery is put in the standard testing condition for 8 hours. Even if the solar illumination is less than 1,000LX, the rated capacity of the battery should make road stud work normally for 12 hours after 8 hours’ charge. One thing should be noted, if the matching performance of battery is not that good, it will be lack of power in wet weather, which may cause the un-illuminate of solar road stud. If this condition happens, the solar road stud will out of particle value. This is also the limitation of capacitive solar road stud. If being put under the standard testing condition for 8 hours, the rated capacity capacitor can only make the solar road stud work for 12 to 14 hours, that is to say, the capacitive solar road stud is strict with its actual working environment, which should not only have enough sunshine, but should not work in continuous rainy weathers.
Tunnel cable spikes are a more advanced traffic safety facility than solar spikes. It takes solar panels or alternating current as the input source, and controls the working state of the spikes (flashing or always on) through the controller. And tunnel cable spikes are more efficient than solar spikes. The spikes are connected by wires. The control diameter of each group of controllers can reach about 1000 meters.
The intelligent wireless road stud can receive the wireless signal given out by the controllers and work through the signal. There is no wire between the road studs, which is much more convenient for installation. However, the sending and receiving of wireless signal are a difficulty.
