公路交通参数检测器的设计

Design of Detector of Highway Traffic Parameters

提出了一种公路交通参数检测器的设计方案。检测器分为检测模块与处理模块两部分 ,利用 L C并联谐振电路与锁相环工作原理 ,设计了基于单片计算机的检测模块 ;根据检测器的性能要求 ,设计了基于单片计算机的处理模块 ,完成对数据的采集、处理、存贮与传输。本检测器具有实用性好、抗噪声与防串音能力强。

A designe scheme for detector of the highway traffic parameters is presented in this paper. The detector is composed of detection module and transaction module. The design of the detection module is based on the microcontroller, using the resonance circuit and the working principle of the PLL (Phase Locked Loop). The transaction module which is based on the microcontroller is designed according to the performance index of the detector. The transaction module can accomplish the tasks of the data's acquisition, transaction, storage and transmission. This detector is superiority in practicability, anti-jamming, stabilization and network connections.
