Abstract

The invention discloses a compressed air foam fire fighting truck as well as an operation control device, a system and a method thereof. The control device comprises a receiver and a controller, wherein the receiver is used for receiving a water absorption manner of the fire fighting truck, and the controller is used for executing the following steps: carrying out corresponding water absorption control by the fire fighting truck according to the water absorption manner; controlling an engine to start; controlling an air compressor and a water pump power takeoff to engage the gear; controlling a foam proportion controller to mix foam and water; and adjusting the rotating speed of the engine, so that the rotary speed reaches a predetermined value or the pressure of a compressed air foam injection orifice reaches a predetermined value to realize reliable control on operation of the compressed air foam fire fighting truck so as to avoid equipment damage probably caused by mis-operation.

Description

technical field [0001] The invention relates to the field of fire trucks, in particular to a compressed air foam fire truck and its operation control device, system and method. Background technique [0002] At present, when a compressed air foam fire truck is operating, it is usually necessary to complete a series of operations such as selecting the water absorption method, putting the air compressor in gear, putting the water pump power take-off into gear, opening the foam ratio controller, opening the foam outlet valve, and adjusting the engine speed. . The above operations need to be performed strictly in the correct order. At present, all the above-mentioned operations are performed manually by operators. Therefore, in the actual operation process, due to human factors such as the operator's proficiency, misoperation is easy to occur. Once misoperation occurs, it may cause dangerous situations such as idling of the water pump and pressure holding that do not conform t...
