The invention discloses a lifting weighing method, a lifting weighing system and a mining dump truck. The lifting weighing system comprises a pressure sensor, a controller, a proximity switch, a tilt angle sensor, an engine ECU, a GPS, a displayer and the like. The lifting weighing method comprises the following steps: measuring the lifting pressure when the cargo compartment is lifted, and calculating the cargo weight according to the maximum value of the lifting pressure in combination with the parameters of the whole vehicle. Meanwhile, the system further has three early warning protection functions: when the inclination angle of the vehicle does not meet the requirement, an alarm signal is sent out, and lifting is forbidden; when the cargo compartment does not fall in place and the car is started, reminding information is sent out, the rotating speed of an engine is limited, and cylinder pulling is prevented; when it is detected that the vehicle is overweight, alarm information is sent out, and if the number of overload times is too large, the engine rotating speed is limited. In this way, the cargo weight can be weighed only by lifting the cargo compartment by a small angle, and the system is simple and high in reliability.

    本发明公开了一种举升称重方法、举升称重系统及矿用自卸车,举升称重系统包括压力传感器、控制器、接近开关、倾角传感器、发动机ECU、GPS、显示器等。举升称重方法为:通过测量举升货厢时的举升压力,根据举升压力最大值结合整车参数计算货物重量。同时,该系统还具有三种预警保护功能:当车辆倾角不满足要求时,发出报警信号并禁止举升;当货厢没有落到位且动车时,发出提醒信息并限制发动机转速,防止拔缸;当检测到车辆超重时,发出报警信息,若超载次数过多,则限制发动机转速。由上可得,本发明只需将货厢举升一个较小的角度,就可以称出货物重量,系统简单,可靠性高。
