Because the solar synchronous road stud works in a synchronized flashing mode, it is usually used as a road edge, green belt marking, deceleration sign, obstacle indication, etc.; Synchronous flashing solar road stud is a very effective city beautification, anti-fog guidance, road marking Strengthen technical means.
In the wireless state of solar synchronous road studs, the current technologies adopted by synchronous flashoing solar road studs mainly include: closed-loop control mode, interlocking mode, and short-period embedded control mode. The method is to set a main control wireless transmission source, set a receiver on the flashing solar road stud, and control the work of the solar road stud in its coverage area through the wireless transmission source. The current control radius of this method is usually 50 to 150 meters. In addition, the long-distance synchronization is very expensive and it is difficult to achieve long-distance synchronization. At the same time, it is also subject to the radio frequency resources and the transmission power of the main control transmission source;
The second type of synchronization technology used by the newer synchronized flashing solar road studs is the interlocking control method. This technology uses interlocking to lock the working state between the flashing solar road studs. This type of synchronized flashing solar road stud usually requires approximately The interlock period of 2 to 3 minutes, after the weighted interlock is locked, the synchronization state can be maintained all the time. This technology can achieve chain synchronization within the line of sight, without external control equipment, no synchronization limit distance requirements, and long-distance installation. According to actual measurement, the maximum error of the 10-kilometer section within 24 hours is less than 50 milliseconds.
The latest solar road stud synchronization technology is the short-cycle embedded control technology. This technology is currently the most effective solar road stud synchronization method. It uses the preset short-cycle embedded control technology to directly start the built-in short-cycle synchronization control. This method realizes the high-precision synchronous work of discrete installation of synchronized flashing solar road studs. The 24-hour synchronization error is usually less than 10 milliseconds, and this technology does not require the maximum installation distance, which can achieve long-distance installation under the most convenient conditions (compared with ordinary solar There is no difference in the installation of solar road studs). Synchronized flashing solar road studs based on short-period embedded control technology can also achieve on-site color replacement, on-site adjustment of the flashing cycle, and on-site adjustment of brightness, which was unimaginable in the past.
Another type of synchronous flashing road stud is a wire stud, also called an active road stud. Through the wire connection, the battery and the circuit can be replaced, and it is more resistant to pressure, more stable, and has a longer life.
