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.
本发明公开了一种高速公路ETC检测车的采集预警及自动启停装置,包括:天线升降机构、激光雷达模块、协议监听天线、协议监听模块、电子标签、ETC数据采集主机、频谱传感模块、通讯模块、GPS模块、频谱传感天线阵和ETC预警与自动启停模块。本发明能够实现高速公路在正常交通环境下,不停车、不封路、不需要人工参与情况下,对收费站和门架系统的ETC系统性能指标的实时监测,获取空中交易时间、帧通信时间、帧数据、交易过程数据、交易成功率、占用带宽、载波频率、最大场强等指标和参数,并通过长期数据的积累和数据挖掘实现对RSU是否正常运行、交易是否正常、交易失败原因等进行定位和判断,为ETC的稳定运营和科学管养提供技术依据和解决方法。
