Multilane speed measuring and block port triggering method and device based on microwaves

Abstract

The invention discloses a multilane speed measuring and block port triggering device based on microwaves. The device comprises a power supply module, an upper computer configuration module, a microwave radar sensor, a signal processing module, a video configuration module, a video sensor and a display storage module. The invention further discloses a multilane speed measuring and block port triggering method based on the microwaves, which comprises the steps that S1, module configuration is performed, and a trigger position is set; S2, the microwave radar sensor scans a detection region; S3, a radar detects target information and performs judgment on an illegal act; S4, the video sensor snapshots; S5, the video sensor performs recognition on license plate, size and vehicle model information; S6, pictorial information of all vehicles is generated; and S7, platform storage and illegal act evidence collecting are performed. The method and the device disclosed by the invention ensure that one microwave radar sensor can cover multiple lanes, and each lane is equipped with video sensor coverage, thereby being high in economic benefit, and suitable for application and popularization.

Description

Technical field [0001] The present invention belongs to the field of intelligent transportation. More specifically, the present invention relates to a microwave-based method and device for multi-lane speed measurement and bayonet triggering. Background technique [0002] The speed measurement technology widely used in road vehicle intelligent monitoring and recording system mainly includes ground sensing coil, video, laser and radar detection methods. [0003] Ground induction coil detection is when the vehicle enters the loop induction coil to form a magnetic field, which causes the frequency or phase of the tuning current in the circuit to change. The detection processing unit responds to the frequency or phase change to obtain an output signal for detecting the vehicle. The speed is calculated by dividing the distance between the front and rear coils by the time difference of the vehicle passing the coils, which has the advantages of low cost, high accuracy, and high reliability...
