The present invention provides an information acquisition method and device, a free-flow toll collection system and a storage medium, wherein the method includes: receiving a first trigger signal sent by a vehicle detection subsystem, wherein the first trigger signal is a vehicle detection subsystem The trigger signal sent after detecting that a vehicle passes the scanning section; in response to the first trigger signal, scan the target area corresponding to the scanning section; in the case of scanning to the OBU from the target area, through the roadside unit RSU and OBU Track transactions and get transaction information. The present invention solves the problem of low transaction success rate in the free-flow toll collection system in the related art due to the weak cooperation ability among the various subsystems.
Description
technical field [0001] The invention relates to the field of intelligent transportation, in particular to an information acquisition method and device, a free-flow charging system and a storage medium. Background technique [0002] In order to improve the traffic efficiency of expressways, toll stations at provincial borders on expressways can be canceled to realize free-flow tolling. The free-flow toll collection system may include: a transaction subsystem, a capture subsystem and a vehicle inspection subsystem. This system can charge and inspect passing vehicles without affecting the normal passage of vehicles. Therefore, higher requirements are put forward for the charging success rate and audit accuracy rate of the system. [0003] In the current free-flow toll collection system, the vehicle detection subsystem triggers the capture subsystem to complete the inspection task, and the transaction subsystem independently completes the toll collection function. [0004] The...
