The solar synchronized road studs refers to the solar road studs installed flickering in the same frequency, and work synchronized in the unity condition. In the condition of wireless, the technologies adopted to the solar synchronized road studs are mainly: closed-loop control technology, interlocking technology, and short period embedded control technology.
closed-loop control technology refers to the technology that a wireless master control emitter is set, and a receiver is installed in the solar synchronized road studs, which can control the solar road studs in its coverage area can work synchronized through the control of the wireless emitter, and the radius of this control technology can be in the range of 50 to 150m. It is expensive and difficult to reach the aim of making the solar road studs work synchronized within long distance. In addition, it is enslaved to the wireless frequency resources and the transmitted power of the mater controlled emitter.
The second advanced technology for the solar synchronized road studs uses the interlocking technology, which can locking the working condition of the solar synchronized road studs through interlocking. This type of solar synchronized road studs needs the interlocking period of 2 to 3 minutes when start-up, and it can maintain the synchronized condition if it is weighted interlocked. This technology can realize the chain-synchronized within the apparent distance, and there is no need for external control facilities. There is no demand for the distance of synchronized work for the solar road studs, and it can be installed in long distance. According to the actual measurement, the deviation for 24 hours is less than 50ms in the distance of 10 miles.
Short period embedded control technology is the latest control technology for the solar synchronized road studs, and it is the best technology nowadays. It uses the preset short period embedded control technology to start-up the built-in short period synchronized control method to realize high-precision synchronized work for the solar road studs installed dispersed. The deviation for 24 hours is usually less than 10ms and there is no distance require for this technology. It can realized long distance installation in the most convenient condition and there is no difference with the installation of the ordinary solar road studs. For the short period embedded control technology can realized the change of color, the adjustment of flicking period and brightness on the spot, which is unimaginable in previous times.
The other kind of solar synchronized road stud has wires, which can be called active solar road stud. It is connected through wires and the battery and circuitry can be changed, which has strong pressure resistance and stability and long service time.
