The Bluetooth mark represents a Bluetooth module installed at the bottom of the vehicle, and when the vehicle is located in the area of the dynamic wireless charging system and needs to be subjected to clock synchronization, the Bluetooth module at the vehicle-mounted end is started to receive clock synchronization information transmitted by the ground Bluetooth module.
Fig. 2 is a schematic diagram of a ground wireless charging system, which includes a master 5, a slave 3, a position induction coil and a bluetooth module.
The host 5 is connected with a power grid 7 through a wireless dynamic charging system 6, and obtains clock information from the power grid. The clock information of the power grid is absolutely synchronous and reliable by relying on a wide-area synchronous clock system in the power industry.
The slave 3 is positioned at each section of charging guide rail on the ground, the slave 3 and the master 5 are connected through the Ethernet to form a local area network of the master 5 and a plurality of slaves 3, and the clock information of the master 5 is synchronized with each slave 3.
The dotted line frames at both sides of the charging rail coil represent ground position induction coils, which are disposed at both sides of the charging rail coil region, which are in and out.
The bluetooth icon represents that the bluetooth module is used as a transmitting module of ground clock information, and the function of the bluetooth icon is to broadcast the clock information in the slave 3 so as to realize that the vehicle-mounted bluetooth module receives the clock information.

The flow chart of fig. 4 is a specific work flow. When a vehicle runs in the area of the dynamic wireless charging system, a magnetic field is established between the position induction coil on the ground and the position induction coil on the vehicle when the vehicle enters or exits, induction current is generated to indicate that the vehicle runs through the area corresponding to the position induction coil, induction current is generated at the entrance end to indicate that the vehicle runs in, the slave machine 3 in the area updates the vehicle running-in information, and the bluetooth module is started after the slave machine 3 in the next area in the local area network obtains an updated state, so that the bluetooth module starts to work before the vehicle runs in the next area.
