Embodiment
Below with reference to accompanying drawing the present invention is described in further detail.
Basic structure of the present invention as shown in Figure 1, it adopts extensive CPLD soft logic array 1, photoelectricity isolated array, power drive array 4, relay array and duty array of display, and a kind of switching output unit at varying input signal is provided.As shown in Figure 1, the present invention includes CPLD soft logic array 1, photoelectricity isolated array, power drive array 4, mode switch relay array 5, manually/intelligent transfer relay 6, manual ringing duty array of display 9 and intelligent signal duty array of display 8.The described CPLD soft logic array 1 that is used for responsible Based Intelligent Control Signal Processing work links to each other with intelligent signal output photoelectricity isolated array 3 with intelligent signal input photoelectricity isolated array 2; Intelligent signal output photoelectricity isolated array 3 links to each other with the power drive array 4 and the intelligent signal duty array of display 8 that are used for low power Based Intelligent Control signal is carried out power drive output again; Power drive array 4 links to each other with mode switch relay array 5 again; Manual ringing input photoelectricity isolated array 7 with manually/intelligent transfer relay 6, mode switch relay array 5 link to each other with manual ringing duty array of display 9; Manually/intelligent transfer relay 6 links to each other with mode switch relay array 5 again.Wherein, each photoelectricity isolated array is responsible for the photoelectricity isolation of various input/output signals; Manually/intelligent transfer relay 6 according to manually/intelligent mode switch-over control signal control model transfer relay array 5; Mode switch relay array 5 is responsible for the switching output of manual control signal and Based Intelligent Control signal; Manual ringing duty array of display 9 is responsible for showing the working condition of each manual control signal; Intelligent signal duty array of display 8 is responsible for showing the working condition of each Based Intelligent Control signal.
Principle of work: (1) Based Intelligent Control signal Processing: different motion controllers, the control signal of its output may be different, for the relative stronger motion controller of function, can export the intelligent pwm control signal of 12 tunnel (6 pairs) simultaneously, each is to suitable/inverse clock rotation of intelligent pwm control signal control turntable or stretching out or the motion of turning back of jib; Owing to suitable/inverse clock rotation of turntable, the motion of stretching out/turn back of each arm oppose, in order to reduce the wasting of resources of system, some motion controller is only exported 6 tunnel intelligence pwm control signal and 6 road direction control signals, this 6 tunnel intelligence pwm control signal is respectively applied for the control of the movement velocity of turntable and each arm, and 6 road direction control signals are then controlled turntable to be clockwise or to reverse and each arm stretches out or turns back.In order to guarantee the compatibility to the different intelligent control signal, mode switching controller need carry out certain processing to input signal, is specifically finished by CPLD soft logic array 1.Isolation enters CPLD soft logic array 1 to all Based Intelligent Control signals through photoelectricity, if input is 12 tunnel intelligence pwm control signals, then output is similarly 12 road pwm control signals, if input is 6 tunnel intelligence pwm control signal and 6 road direction control signals, then handle back output 12 road pwm control signals through CPLD soft logic array 1, concrete which kind of mode that adopts is by the control of direction gating signal, if washout effectively then stop all outputs.(2) the Based Intelligent Control signal drives: because multi-axis motion controller output is low power Based Intelligent Control signal, can not be directly used in the drive controlling of arm support oil cylinder, need to export through after the power drive earlier again, this function is finished by power drive array 4.Miniwatt Based Intelligent Control signal is isolated ingoing power driving array 4 then through photoelectricity again after CPLD handles, switch output through entering mode switch relay array 5 again after the power drive.(3) manual/Based Intelligent Control signal switches output: manual/intelligent transfer relay 6 is according to manual/intelligent mode switching signal control model transfer relay array 5.Under manual mode, manually/intelligent transfer relay 6 is in the normally open position, the mode switch relay array of being made up of 6 double-point double-throw switchs 5 is subjected to its control also to be in the normally open position, and the pwm control signal of such 12 tunnel arm support oil cylinder just directly comes from manual control signal; Under intelligent mode, manually/intelligent transfer relay 6 is in normally closed position, the mode switch relay array of being made up of 6 double-point double-throw switchs 5 is subjected to its control also to be in normally closed position, and the pwm control signal of such 12 tunnel arm support oil cylinder then comes from the Based Intelligent Control signal.(4) the unlike signal duty shows: manual ringing duty array of display 9 and intelligent signal duty array of display 8 are made up of 12 light emitting diodes respectively, corresponding one road working signal of each light emitting diode.When certain road signal was effective, then Dui Ying light emitting diode was lighted, and showed that this road signal is in duty, and light emitting diode then corresponding when the invalidating signal of this road extinguishes, and shows that this road signal is in off working state.The light on and off situation of these status indicator lamps can observe directly from the outside, is convenient to grasp the working condition of mode switching controller internal circuit and the moving situation of each jib.
