Wherein, comprising a management identification number in connection request, when the management identification number that WIFI signal LAN is detected
When identical with the management identification number for prestoring, WIFI signal LAN receives the connection request, does not receive the connection otherwise
Request.
When the fleet that multiple geographical position are closer to is carried out data transmission using the method for the present invention simultaneously, then samely
Can there is multiple WIFI signal LANs and multiple fleet managements end in reason regional extent, if not managed to multiple fleets now
The connection request that reason end is initiated makes a distinction, it is likely that cause what a certain fleet management end produced to the vehicle in other fleets
WIFI signal LAN initiates connection request, now not only results in connection error and data transmission fault, also results in car
The data of vehicle leak and there is potential safety hazard in team.Therefore, present invention employs each connection request comprising a management mark
The technological means of knowledge number, and only work as WIFI signal LAN the management identification number for detecting and the management mark for prestoring
Knowledge number just receives connection request when identical.Consequently, it is possible to the connection request that each fleet management end is initiated includes different pipes
Reason identification number, even if the geographical position of multiple fleets is closer to, each fleet management end also only can be attached in this fleet
The WIFI signal LAN of vehicle generation of the WIFI signal LAN that vehicle is produced without being connected in neighbouring fleet,
So as to ensure that the accuracy and data safety of data transfer.
S4：The WIFI signal LAN of successful connection is presented to a keeper by fleet management end；
S5：Keeper sends a download command to fleet management end；
Wherein, fleet management end is provided with multiple connection identification lights and multiple download buttons, wherein, connect identification light and download
