Truck ETC lane weighing data verification method and system

The invention provides a truck ETC lane weighing data verification method and system. The method comprises the steps of: obtaining an exit axle type obtained through detection of a vehicle by an exittire detector at a first moment, and obtaining the exit weight obtained through weighing of the vehicle by an exit weighing platform at a second moment, wherein the first moment is earlier than or later than the second moment; acquiring a station-crossing file obtained by reading a vehicle-mounted tag on the vehicle by an exit RSU antenna at a third moment, wherein the third moment is earlier thanthe first moment and the second moment; under the condition that an entrance axle type and an entrance weight are obtained through analysis of the station-crossing file, if the entrance axle type isconsistent with the exit axle type and the variation of the exit weight relative to the entrance weight is within a set threshold range, confirming that the vehicle passes weighing data verification;and under the condition that
