Acquisition early warning and automatic start-stop device of highway ETC detection vehicle

Abstract

The invention discloses an acquisition early warning and automatic start-stop device of a highway ETC detection vehicle. The acquisition early warning and automatic start-stop device comprises an antenna lifting mechanism, a laser radar module, a protocol monitoring antenna, a protocol monitoring module, an electronic tag, an ETC data acquisition host, a frequency spectrum sensing module, a communication module, a GPS module, a frequency spectrum sensing antenna array and an ETC early warning and automatic start-stop module. According to the invention, real-time monitoring of ETC system performance indexes of a toll station and a portal system can be realized in a normal traffic environment of a highway under the conditions of no parking, no road closure and no manual participation; indexes and parameters such as air transaction time, frame communication time, frame data, transaction process data, transaction success rate, occupied bandwidth, carrier frequency, maximum field intensity and the like are obtained, and whether the RSU operates normally or not, whether the transaction is normal or not, a transaction failure reason and the like are positioned and determined through long-term data accumulation and data mining, and a technical basis and a solving method are provided for stable operation and scientific management and maintenance of ETC.

Description

technical field [0001] The invention belongs to the technical field of ETC, and in particular relates to a collection, early warning and automatic start-stop device for an ETC detection vehicle on an expressway. Background technique [0002] With the implementation of the country's traffic strategy of canceling provincial toll stations, my country's expressways have basically achieved full coverage of ETC lanes. Facing such a large number of toll stations and ETC lanes of the gantry system in the national road network, the quality of its ETC performance is directly related. It affects the stable operation of the charging system. Therefore, mastering the physical performance and communication related indicators and parameters of ETC is the key to ensure the stable operation of ETC. [0003] Traditionally, ETC-related performance testing is mainly carried out by testing personnel through manual, single-point, random inspection, etc. This method has low detection efficiency, tak...

Problems solved by technology

[0003] Traditionally, ETC-related performance testing is mainly carried out by testing personnel through manual, single-point, random inspection, etc. This method has low detection efficiency, takes a long time, and requires road closure, which poses a huge safety hazard, especially for gantry systems. Detection, the existing detection methods are almost difficult to complete
