Description

Technical Field

[0001] The utility model relates to the technical field of vehicle flow detection devices, in particular to a highway vehicle flow detector. Background Art

[0002] Highway traffic flow detectors are devices used to detect and calculate the traffic flow on highways. These detectors work by detecting the presence of vehicles and obtaining relevant information about the vehicles, such as vehicle type, speed, distance from the front to the rear, and number of vehicles, and then using this information to calculate the traffic flow. Specifically, the detectors may use technologies such as frequency modulated microwave emission, reflected wave deviation, and high-precision sensor measurement to determine the presence of vehicles and identify vehicles on the road.

[0003] For example, the patent document with publication number CN114596717A discloses a vehicle flow detector based on a traffic light integrated with TOF ranging, specifically disclosing a DTOF ranging module and a traffic light, wherein the DTOF ranging module is installed at the bottom of the traffic light, and two transmitting tubes are symmetrically arranged on the bottom surface of the DTOF ranging module, a U-shaped seat is fixed on the top surface of the DTOF ranging module, and two clamping plates are movably arranged on the front and rear surfaces of the U-shaped seat; by installing the DTOF ranging module at the bottom of an ordinary traffic light, a light signal is emitted vertically downward to the ground, so as to realize the ranging function for distinguishing whether an object passes, thereby further determining whether a vehicle passes, thereby realizing the vehicle flow detection function.

[0004] However, the existing highway traffic flow detector cannot adjust the detection direction. If the detector cannot adjust the direction, it may detect vehicles from multiple directions at the same time, resulting in the inability to accurately distinguish traffic flows in different directions. This will affect the traffic management center's accurate judgment of road traffic conditions. For this reason, we propose a highway traffic flow detector. Utility Model Content
