The invention discloses an aerial ladder fire truck platform overload control system and method.The method comprises the steps that a master controller judges whether a fire truck is in a stable state or not based on vertical supporting leg bearing pressure Fij, and if the fire truck is in a non-stable state, a ladder assembly of the fire truck is controlled to stop the action of increasing the amplitude; if the fire fighting truck is in a stable state; the master controller calculates the getting-off stable moment Ms of the fire fighting truck according to the telescopic displacement Li of the horizontal supporting legs and the rotation angle # imgabs0 # of the rotary table, and calculates the getting-on tipping moment Mz of the fire fighting truck according to the angle alpha of the ladder assembly, the total length L of the ladder assembly and the platform load G1; the master controller controls the fire fighting truck to act based on the getting-off stabilizing moment Ms and the getting-on tipping moment Mz; the force distribution condition of each supporting leg is monitored in real time, so that overload operation of the fire fighting truck platform can be realized, and the problem that the operation capability is influenced due to a narrow operation scene is solved.
本发明公开了一种云梯消防车平台超载控制系统及方法,包括所述总控制器基于垂直支腿承受压力Fij判断消防车是否处于稳定状态,若消防车处于非稳定状态,控制消防车的梯架停止幅度增加的动作;若消防车处于稳定状态;所述总控制器根据水平支腿伸缩位移Li和转台回转角度#imgabs0#计算消防车的下车稳定力矩Ms,根据梯架角度α、梯架总长度L和平台负载Gl计算消防车的上车倾翻力矩Mz;所述总控制器基于下车稳定力矩Ms和上车倾翻力矩Mz控制消防车动作;通过对各支腿力分布情况进行实时监测,保证实现消防车平台能够超载作业,缓解了因为作业场景狭小下的影响作业能力的问题。
