    • PROBLEM TO BE SOLVED: To provide a cargo deck vibration judging device considering not only vibrations on the cargo deck floor of a vehicle, but also the vibration condition of a cargo on the deck.
      SOLUTION: The frequency transfer function between the vertical acceleration of the cargo deck (120) of the vehicle (100) detected by a sensor (11) and the vertical acceleration of the cargo (200) on the deck (120) detected by a sensor (12) is calculated. Moreover, the frequency distribution map of the peak value of the transfer function is generated, and a frequency band accounting for a prescribed percentage is specified. When a value obtained by subjecting either one of the output signals to band-pass filter processing by using the frequency band exceeds a threshold, an alarm signal is output.

    • 要解决的问题:提供一种考虑车辆货物甲板地板上的振动的货物甲板振动判断装置,以及甲板上的货物的振动条件。 解决方案:检测由传感器(11)检测到的车辆(100)的货物甲板(120)的垂直加速度与甲板(120)上的货物(200)的垂直加速度之间的频率传递函数 由传感器(12)计算。 此外,生成传递函数的峰值的频率分布图,并且指定了规定百分比的频带。 当通过使用频带对输出信号中的任一个进行带通滤波处理而获得的值超过阈值时,输出报警信号。 版权所有(C)2008,JPO&INPIT
