In 2017, with the emergence of the bicycle sharing mode, the traditional travel field was instantly overturned. However, while it brings convenience to people's life, it also causes some disadvantages. When there is a lack of management of "stop and release as needed", it becomes a disorderly stop and release, which not only brings a lot of inconvenience to others, but also brings great troubles to city managers and bicycle-sharing operators. In order to further improve the parking order of shared bicycles, Bluetooth electronic fence technology has become a feasible solution. Bluetooth electronic fence technology is based on Bluetooth's positioning, broadcasting and transmission functions to realize vehicle entry management and vehicle on-site statistics. What Is Bluetooth Electronic Fence? Bluetooth electronic fence refers to the platform planning and setting up a certain area, allowing and standardizing the parking of shared bicycles in this area, and placing Bluetooth beacon equipment in this area, which can detect the shared bicycles installed with Bluetooth within a radius of 50 meters. If the vehicle is parked beyond the specified area or traveling beyond the specified area, the system will generate a series of alarm notices, so that the manager can check and know the dynamics of the relevant vehicle in time and take corresponding measures to deal with it. The public electronic fence realizes data interaction through Bluetooth, and its signal and data coverage accuracy can reach Yami level, management is accurate to vehicles, and can be compatible with the standard parking of different brands sharing bicycles. The sharing bicycle Bluetooth electronic fence scheme is based on the integration of bicycle perception, electronic fence induction, long endurance and other technologies, through Bluetooth wireless broadcast, positioning and transmission services, under the premise of ensuring the long endurance of nodes, to achieve stable and reliable electronic fence services such as bicycle perception, fence induction, etc., to achieve the interconnection of sharing bicycle, bicycle parking point, operation service platform, effectively solve the urban management difficulties caused by the disordered development of Internet shared bicycles. Three Implementation of Electronic Fence There are three main technical implementation methods of electronic fence: Electronic fence based on satellite positioning technology (GPS); Use the Bluetooth device of the bike lock to read the electronic fence of the Bluetooth label fixed at the parking point; The Bluetooth of the user's mobile phone reads the Bluetooth electronic tag of the parking point and the electronic fence of the vehicle-mounted Bluetooth tag; The first and second technologies rely on satellite positioning technology and Bluetooth device on the bike lock respectively, which is relatively hidden visually. The third type of installation and deployment is extremely convenient, which is convenient f...
