Abstract

The present invention provides an information acquisition method, device and system, wherein the method includes: receiving target information sent by a vehicle weighing device, wherein the target information is used to identify that the target vehicle has passed the body part of the vehicle weighing device The length of the target vehicle included in the body part is provided with an on-board unit OBU; according to the total length between the vehicle weighing device and the scanning device and the length identified by the target information, determine the target distance between the OBU and the scanning device ; Control the scanning range of the scanning device to include the target distance, so as to scan the OBU to obtain the OBU information carried by the OBU, wherein the OBU information is used to debit the target account. The present invention solves the problem that the ETC system in the related art has the problem of billing failure because the vehicle body is too long and the billing time left for the ETC system is short.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an information acquisition method, device and system. Background technique [0002] Electronic Toll Collection (ETC) is an advanced road toll collection system, which can quickly complete toll collection and reduce traffic delays and congestion caused by toll payment. Electronic Weight Toll Collection for trucks (Electronic Weight Toll Collection, referred to as truck ETC or EWTC) is a technology that combines dynamic weighing with ETC technology and applies it to trucks for non-stop toll collection. [0003] In related technologies, the truck ETC system simply combines the dynamic weighing system and the ETC trading system together, and then adds or modifies some modules on this basis to improve the overall system, such as the ETC pre-reading system, vehicle electronic tags (also known as Vehicle-mounted unit, On Board Unit, referred to as OBU) queue, judging whether automati...
