High accuracy virtual electronic fence management technique based on GNSS

As bike-sharing has been emerging, it does not only satisfy people's large amounts of requirements of short distance travel, but also assists in eliminating URBAN ILLS, such as traffic congestion, environment contamination and so on. Its convenience of usage has been greatly promoted when getting rid of parking piles, but some newly situations, such as irregular parking behaviors lead to traffic environmental problems, which has an impact on the sustainable development of the bike-sharing. In this paper, high precision virtual electronic fence technology based on GNSS, intelligent terminal and precision orientation algorithm was proposed. Moreover, the bike-sharing's regular parking management and the accuracy of intelligent scheduling come true via BDS (compatible with GPS s GLONASS and GALILEO). Sub-meter positioning precision was achieved in the virtual electric fence technique, and the accuracy rate of lairaging of the bike-sharing has been more than 90%.
