【摘要】 设计了一种有效的模拟信号调理方法,并研制了一种基于全向振动传感器的信号采集探测系统,对车辆振动信号的数据进行采集与检测。根据传感器的输出可判断周围空间内车辆的存在与否,并对该信号进行试验研究,试验结果表明:车辆与人的信号输出有很大的差异,从而可以区分人和车辆。当车辆沿不同距离通过传感器时,传感器输出变化规律不同,故该信号采集与探测能探测车辆。更多还原

【Abstract】 A kind of valid analog signal regulated means is designed.Based on which,a signal acquisition and detecting system of collecting and detecting shaky vehicle signal is developed.Whether a vehicle is present or not can be judged by the sensor output,the sensor output is tested.Test result shows it has great difference between people and vehicle,then people are distinguished from vehicle.When the detected vehicle is moved over the sensor,the output changes are different,the signal acquisition and detecting system can realize the function of vehicle.更多还原
