The boom extends and retracts through the length sensor to collect the length of the boom, the angle sensor to collect the pitch angle of the boom, the angle encoder to collect the slewing angle, and the oil pressure sensor to collect the pressure of the amplitude cylinder, and then the independently-developed high-performance controller realizes the functions of boom extension and retraction, amplitude change and its composite action control, working bucket leveling control, water cannon control, soft leg protection, virtual wall limitation, and the torque limitation of the whole machine, etc.; combined with the robot control technology, the kinematics positive and negative solution realizes the intelligent control such as one-key automatic unfolding of multi-attitude of the boom, automatic leveling of the frame, and automatic spreading of legs. Combined with the robot control technology, the kinematics of positive and negative solutions to realize the boom multi-attitude one-key automatic unfolding, one-key automatic retraction, automatic frame leveling, automatic spreading of outriggers and other intelligent control; based on the power curve of the engine and the pump to establish a special power-matching control algorithm model, the flow of composite action distribution, in order to maximize the efficiency of the whole machine; with the optional remote control platform, the operator can be away from the fire scene of the safety zone accurate remote control The optional remote control platform allows the operator to precisely and remotely control the fire engine in a safe place far away from the fire scene.
System advantages:
High control accuracy, the error is less than 0.5%;
Fast control response, less than 2ms;
Smooth operation without lag; rapid start without impact; sensitive micro-movement fast speed regulation;
