The operation control of the aerial work platform is generally divided into platform control and turntable control. The platform control can operate the straight-crank arm type aerial work platform to walk, turn, change amplitude upwards, change amplitude downwards and the like through a handle and an operating button. And the rotary table control is used as an auxiliary operation mode, and the operation is performed through a rotary table operation panel, so that the arm support on the straight-crank arm type aerial work platform can be operated to act.
In the process of applying the aerial work platform, safety accidents caused by misoperation or visual field problems of operators occur every year, and how to practically protect the operators from personal injury caused by the misoperation or the visual field problems is a problem to be solved urgently by the current aerial work platform. Neither the national standard (GB/T25849) nor the European standard (EN280) of the aerial work platform can consider the complexity of the construction environment and the risks caused by human factors of operators.
In view of the above, as shown in fig. 1 to 3, in one aspect of the present disclosure, an active defense device for an aerial work platform is provided, including:
