SYNCHRONISATION CONTROL METHOD FOR SOLAR ROAD STUDS

WIPO Patent Application WO/2010/133145

A1

A synchronization controlling method for solar road studs is provided. The method uses the time service function of a geosynchronous positioning satellite, and performs synchronous working control with the same time source on the solar synchronization road studs installed discretely. Said solar synchronization road stud comprises a shell, a solar cell, an accumulator battery, a charge-discharge and on-off control circuit, a miniature satellite receiving antenna, a satellite receiving module, a microprocessor, and an electroluminescent device. After receiving a time service signal of the geosynchronous positioning satellite by said miniature satellite receiving antenna, the time information and the second synchronizing information are analyzed and extracted through the satellite receiving module. After receiving a second synchronizing signal offered by the satellite receiving module, the microprocessor controls the synchronous turn-on and turn-off of the electroluminescent device according to preset flicker frequency and flicker duty cycle. Using synchronizing time to perform synchronous working control on the solar road studs, above control method is not limited by factors such as the length and trend of roads, and is simple and convenient in implementation and reliable in control.
