What is a solar spike

Background editor due to the continuous development of the solar energy industry, in recent years, in the national implementation of highway safety assurance projects, various high-tech traffic safety when setting fog on the highway visibility pictures (2) and products are favored by the industry. The extensive application of these traffic safety facilities and products has played an important role in improving road traffic safety and reducing traffic accidents. Among all kinds of traffic safety facilities or products, solar energy road studs can clearly mark the road outline and edge in rainy, foggy weather and road curve, guide the driver's vision, and then eliminate the hidden danger of road safety. The solar energy spike can play an important role in the rain and fog weather, as well as in the curve to draw the road outline, guide the driver's line of sight and eliminate the safety hazards. Features: the brightness of ordinary street studs is only 300-400 MCDs, while the brightness of solar studs is more than 2000 MCDs, which is 6-7 times of the former. The high-intensity light can break through the rain and fog at night and guide the driver safely and effectively. The active light and dynamic warning solar spikes flash at a certain frequency at night, and human vision is more sensitive to changes, so its dynamic warning function is very strong. Active light-emitting can not only avoid the interference of rain and fog to the greatest extent, but also get rid of the dependence on car lights, with a longer visual distance and better effect. Solar studs play a very important role in the rain and fog weather and in the curve of the road contour, guide the driver's line of sight and eliminate safety hazards. Working principle: edit the solar panel to absorb the sunlight during the day and convert the solar energy into electric energy. The protruding solar studs (2 pieces) are stored in the energy storage device (battery or capacitor). At night, the electric energy in the energy storage device is automatically converted into the light energy (controlled by the photoelectric switch), and the road outline is drawn by the light emitted by the led to guide the driver's vision. According to the different installation positions, the solar studs can be divided into embedded type and protruding type. The former is generally used in the center line, while the latter is generally used in the edge line. This is because the requirements for compressive performance of the solar studs installed in the middle line are particularly high. In order to solve this problem, we have to embed the solar studs in the ground, only about 5 mm above the ground. However, the solar studs used in the edge line do not have very high requirements for compressive performance, and they can still work effectively when protruding from the ground. According to the different energy storage components, the solar spike can be divided into two types: capacitive type and battery type. The former has a service life of five to seven years, while the latter has a service life of one to three years. Because the embedded solar studs do great damage to the road surface, and the cost of the capacitive solar studs is too high, so the most widely used solar studs are the convex solar studs. The performance index editor measures the performance of a solar spike from the following aspects. Compressive performance if the solar energy spike can not bear a certain pressure, it will be easily broken after the car rolling or impact, so it can not work normally, so compression is a basic condition for the normal work of the solar energy spike. But the problem is that the solar spike itself is an electronic product, including the electronic part. It is not easy to make the electronic part have a higher degree of compressive performance, so generally speaking, the compressive performance of the solar spike is worse than that of the ordinary spike. As of 2014, the technical requirement of the Ministry of transport is 10 tons. There are several ways to effectively improve the compressive performance of the solar spike: first, the exposed solar panel adopts PC bulletproof material to enhance the compressive capacity of the electronic part; second, IC control is used as far as possible to reduce the volume of the electronic circuit and reduce the pressure on the electronic part; Third, some stiffeners are designed on the shell to share the pressure of the electronic part. Sealing performance if the solar spike is not completely sealed, it will naturally leak water, which will cause a short circuit in the circuit, and the consequences are catastrophic, so a qualified solar spike sealing performance must also pass the test. There are several ways to improve the sealing performance of solar energy spikes: (1) separation design. The LED lampshade and internal circuit board adopt the isolation design, even if the LED lampshade is broken, the interior of the solar spike still can not seep; (2) the strong neutral bonding material is used to ensure that the solar panel, the LED lampshade and the spike shell are tightly bonded, and there is no gap in the middle. Compared with the reflective road studs, one of the most important characteristics is the high luminous intensity. This indicator is required by the Ministry of transport to be 2000 MCDs. One of the important factors that determine the life of the solar spike is the life of the battery, and the choice of the battery is very important. Up to 2014, there are two types of batteries on the market for reference. One is that after 500 times of charging and discharging, the battery capacity is reduced to 50%; the other is that after 1000 times of charging and discharging, the battery capacity is reduced to 79%. [2] The battery life should not only be long enough, but also be able to work normally in a large temperature range. The inside of the battery is a chemical substance. If the temperature is too high or too low, the battery will not work. The working temperature range of the solar spike battery must meet the requirements of the actual use environment. The requirement of the Ministry of transport is - 10 degrees to 50 degrees, and the actual environment often exceeds this range, which puts forward higher requirements for batteries. The design of electronic circuit board must follow the simple and effective design principle, not artificial
