The invention provides a vehicle body acceleration monitoring device and system and a 25t axle load aluminum alloy coal hopper car. The vehicle body acceleration monitoring device comprises a first MEMS acceleration sensor, a second MEMS acceleration sensor and a control unit. The first MEMS acceleration sensor, the second MEMS acceleration sensor and the control unit are all arranged on the side,close to a bogie, of the vehicle body. The first MEMS acceleration sensor is used for detecting a first acceleration value of the vehicle body vibrating in a first direction and determining whether to output a trigger signal or not according to the first acceleration value. The projection area of the bogie on the vehicle body covers the projection areas of the first MEMS acceleration sensor and the second MEMS acceleration sensor on the vehicle body. The control unit is electrically connected with the first MEMS acceleration sensor and the second MEMS acceleration sensor. And when the controlunit receives the trigger signal, the control unit collects a second acceleration value of the vehicle body vibrating in the first direction through the second MEMS acceleration sensor and outputs the second acceleration value.
本申请提供了一种车体加速度监测装置、系统及25t轴重铝合金煤炭漏斗车。所述车体加速度监测装置包括第一MEMS加速度传感器、第二MEMS加速度传感器和控制器件。第一MEMS加速度传感器、第二MEMS加速度传感器和控制器件均设置于车体靠近转向架的一侧。第一MEMS加速度传感器用于检测车体在第一方向振动的第一加速度值,并根据第一加速度值确定是否输出触发信号。转向架在车体的投影面积覆盖第一MEMS加速度传感器和第二MEMS加速度传感器在车体的投影面积。控制器件分别与第一MEMS加速度传感器和第二MEMS加速度传感器电连接。当控制器件接收到触发信号时,控制器件通过第二MEMS加速度传感器采集车体在第一方向振动的第二加速度值,并输出第二加速度值。
