Abstract

Present systems for road traffic surveillance largely utilize MEMS magnetometers for the purpose of vehicle detection and classification. Magnetoresistive sensing or LR oscillation circuitry are technologies providing the sensors with the competitive advantage which lies in the energy efficiency and low price. There are several chip suppliers on the market who specialize in the development of these sensors. The aim of this paper is to compare available sensors from the viewpoint of their suitability for traffic measurements. A summary of the achieved results is given in the form of the score for each sensor. The introduced sensor chart should provide the audience with knowledge about pros and cons of sensors, especially if intended for the purposes of road traffic surveillance. The authors in this research focused on the specific situation of road traffic monitoring with magnetometers placed at the roadside.

摘要

目前，道路交通监控系统主要利用 MEMS 磁强计进行车辆检测和分类。磁阻传感或 LR 振荡电路技术为传感器提供了竞争优势，其优势在于能源效率和价格低廉。市场上有几家专门从事这些传感器开发的芯片供应商。本文的目的是从适合交通测量的角度比较现有传感器。每个传感器的得分形式给出了所获得结果的摘要。所介绍的传感器图表应使受众了解传感器的优缺点，特别是如果打算用于道路交通监控的话。本研究的作者主要关注路边放置磁强计的特定道路交通监测情况。
