The invention relates to a tank truck rollover early warning device and system, and the device comprises a liquid level sensor which is disposed in a tank body of a tank truck, and is used for obtaining the height of liquid in the tank body; an first inclination angle sensor which is arranged on the tank truck and is used for acquiring road superelevation; a second inclination angle sensor which is arranged on the tank body and used for obtaining the inclination angle of the tank body; an acceleration sensor which is arranged on the outer side of the tank body and used for acquiring centrifugal acceleration of the tank truck; a torque obtaining module which is used for obtaining vehicle rollover promoting torque and vehicle rollover blocking torque according to the liquid height, the roadsuperelevation, the inclination angle of the tank body, the centrifugal acceleration and the tank truck parameters; and a rollover early warning module which is used for carrying out rollover early warning according to the vehicle rollover promoting moment and the vehicle rollover hindering moment. Rollover early warning is carried out according to the vehicle rollover promoting moment and the vehicle rollover hindering moment, the accuracy of vehicle rollover early warning is improved, and therefore the transportation safety of the tank truck is improved.
本发明涉及一种液罐车侧翻预警装置及系统,所述装置包括:液位传感器,设置在液罐车罐体内部,用于获取罐体中液体高度;第一倾角传感器,设置在液罐车上,用于获取道路超高;第二倾角传感器,设置在罐体上,用于获取罐体的倾斜角;加速度传感器,设置在罐体外侧,用于获取液罐车的离心加速度;力矩获取模块,用于根据液体高度、道路超高、罐体的倾斜角、离心加速度和液罐车参数获得促使车辆侧翻力矩和阻碍车辆侧翻力矩;侧翻预警模块,用于根据促使车辆侧翻力矩和阻碍车辆侧翻力矩进行侧翻预警。本发明根据促使车辆侧翻力矩和阻碍车辆侧翻力矩进行侧翻预警,提高了车辆侧翻预警的准确性,从而提高了液罐车运输的安全性。
