Wide-adaptability container type compressed air foam device and control method

The invention provides a wide-adaptability container type compressed air foam device which comprises a foam generator, an air compressor, a centrifugal water pump, a foam pump A and a foam pump B which are arranged in the device, and further comprises a control module and a power supply module, and the centrifugal water pump, the foam pump A and the foam pump B are communicated to a main pipeline through a water pipeline and a foam pipeline respectively; the main pipeline is connected with the foam generator, the air compressor is connected with the foam generator through an air pipeline, and the foam generator is further communicated with the foam output port through an output pipeline. The invention further provides a control method of the wide-adaptability container type compressed air foam device, a three-input single-output PQ control algorithm is adopted, the function that the flow of three paths of media is controllable is achieved through PID algorithms of all the sub-paths, the range of the foam conf
