A single-lane ultra-high monitoring method, device, equipment and storage medium

Abstract

The invention provides a superelevation monitoring method and device for a single lane, equipment and a storage medium. The method comprises the steps that a reflection signal of a target lane is collected through a frequency-modulated continuous-wave millimeter-wave radar, and the reflection signal and a local oscillation signal are mixed for obtaining an intermediate-frequency signal, wherein the local oscillation signal is a signal with the frequency identical to that of a transmission signal at the same moment of radar generation; the intermediate-frequency signal is subjected to one-dimensional FFT frequency spectrum analysis for obtaining a distance frequency spectrum; according to the distance frequency spectrum, a preset distance amplitude threshold value, a height between the radar and the ground and a maximum height of permission passage of the lane where the radar is located, a speed frequency spectrum of a potential superelevation target object is obtained; when a peak value spectrum line exceeding a preset speed amplitude threshold value does not exist in the speed frequency spectrum, superelevation of the potential superelevation target object corresponding to the speed frequency spectrum is judged. According to the method, the influence of high-altitude quick-flight objects such as birds can be removed, whether or not violation superelevation of a vehicle which passes through the area under the radar exists can be accurately judged, the respond speed is high, and the method is accurate and efficient.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a superelevation monitoring method, device, equipment and storage medium of a single lane. Background technique [0002] With the development of the times, the modernization of the city is changing with each passing day, and the complexity of urban roads is increasing day by day. In order to alleviate the pressure of urban traffic, cities have issued various regulations and policies on traffic restrictions, speed restrictions, and height restrictions for different roads. In order to pursue their own economic benefits, many engineering companies or product suppliers often carry out overweight and overheight road transportation, and timely and accurate capture of overheight vehicles and efficient handling have become the focus of traffic management departments. [0003] Problems existing in the prior art: [0004] 1. The infrared sensor is used for dete...
