Aspect concrete enforcement, the MT506S of touch screen controller behaviour mechanical ﹠ electrical corporation links to each other with Programmable Logic Controller PLC by the RS422 interface.Programmable Logic Controller PLC is the FX2N-48MK of Mitsubishi.Its input port links to each other with the output of pick off, accepts the output signal of angular encoder and altimeter coder.Angular encoder 6 is KOYO company's T RD-2T2048V, and altimeter coder 7 is KOYO company's T RD-2T1024V.
Angular encoder 6 is installed in the rotating shaft next door of reaping hook arm, link to each other with electric rotating machine by gear, its corresponding relation is: angular encoder 6 rotatable 10 circles, the angle of reaping hook arm 2 rotations is-30 °～120 °, promptly Xuan Zhuan angular range is 150 °, angular encoder 6 corresponding reaping hook arm 2 anglecs of rotation that whenever turn around are 15 °, angular encoder 6 whenever turns around and sends 2048 pulses, if-30 ° of position corresponding angle encoder 60 pulses, when rotating to 0 ° of position, angular encoder 6 must rotate 2 circles, exports 2 * 2048=4096 pulse, send programmable logic controller (PLC) PLC with 4096 pulses, promptly when programmable logic controller (PLC) PLC detects 4096 pulses, therefore reaping hook arm 2 must by detection angles encoder 6 umber of pulses, promptly can be converted into corresponding angle 0 ° of position.
Altimeter coder 7 is installed in the lifting motor next door of column 1 upper end, link to each other with lifting motor by gear, its corresponding relation is: altimeter coder 7 rotations 10 circles, reaping hook arm 2 liftings 40～200cm, be range 160cm, altimeter coder 7 corresponding reaping hook arm 2 liftings of whenever turning around are 16cm, altimeter coder 7 whenever turns around and sends 1024 pulses, if 0 pulse of 40cm position respective heights encoder 7, when being raised to 40+16 * 2=72cm position, altimeter coder 7 must rotate 2 circles, export 2 * 1024=2048 pulse, send programmable logic controller (PLC) PLC with 2048 pulses, promptly when programmable logic controller (PLC) PLC detected 2048 pulses, reaping hook arm 2 must be in the 72cm position.Therefore by detecting the umber of pulse of altimeter coder 6, promptly can be converted into reaping hook arm 2 corresponding height.
Converter is the SY200-007 of Hitachi, and lifting motor is BN80BF, and reductor is W110V80; Electric rotating machine is BN70BF, and reductor is W63UP71.
Software is by mastery routine MAIN, gyrator program XUAN, lifting subprogram SHEN and subprogram 3 are formed, main program flow chart as shown in Figure 5, software PLC language compilation is write the PLC programmable controller by PC.
The flow chart character string is defined as follows:
Angular encoder umber of pulse record value ANGLE
Altimeter coder umber of pulse record value HIGH
Reaping hook arm decline key HIGH-DO
Reaping hook arm lifting key HIGH-UP
The clockwise button ARM-CW of reaping hook arm
The reaping hook arm is counterclockwise button ARM-CCW
Angle corresponding setting height value between ± 30 ° and 0 ° is HE1
Corresponding setting height value was HE2 when angle was 0 °
Angle respective heights setting value between 30 ° and 90 ° is HE3
Angle is that 90 ° of corresponding setting height values are HE4
Angle is that the setting height value is HE1 between 90 ° and 120 °
Reaping hook arm rotation height setting value is HIGH-DOWN1
PLC output lifting motor rising signals HE-UC
PLC output lifting motor dropping signal HE-DC
The positive rotaring signal ARM-CWC of PLC output electric rotating machine
PLC output electric rotating machine reverse signal ARM-CCWC
PLC depositor AC deposits height setting value HE1-HE4
Mastery routine MIAN function is: initialization system and to lifting, and rotary knob detects;
The function of gyrator program XUAN is: height and angle information are carried out calculation process, the output control signal;
The function of lifting subprogram SHEN is: height and angle information are carried out calculation process;
The function of subprogram 3 is: whether decision height drops to the limit, output decline control signal;
Behind the opening initialization, PLC reads in the umber of pulse record value of angular encoder and altimeter coder, and be presented on the touch screen controller, when on touch screen controller, pressing lifting button, program enters lifting and handles subprogram, reads the umber of pulse record value of angular encoder and altimeter coder, judges that angle is whether between-30 ° and 0 °, if, then whether the decision height encoder values is less than setting height value HE1, if then show in this angular range, the reaping hook arm can not collide ground, PLC output reaping hook arm dropping signal HE-DC, this signal drives the lifting motor running by converter, and the reaping hook arm descends, and judge whether the decline button remains valid, if, skip to the subroutine entry place, continue this subprogram of operation, if invalid, then return mastery routine.If not between-30 ° and 0 °, judge whether angle is 0 °, if, then whether the decision height encoder values if altimeter coder value greater than setting height value HE2, show reaping hook arm has the danger on collision ground less than setting height value HE2, do not export the HE-DC signal, the reaping hook arm stops to descend.If angle is not 0 °, then judge whether between 0 ° and 30 °, if then whether the decision height encoder values is less than setting height value HE1, in like manner, judge whether between 30 ° and 90 °, whether same decision height encoder values less than setting height value HE3, otherwise judges whether to be 90 °, and whether same decision height encoder values is less than setting height value HE4, if be not 90 °, must be between 90 ° and 120 °.Guarantee like this between-30 ° to 120 °, when the reaping hook arm descends, neither can collide ground, maximum stroke is arranged again.
When pressing rotary knob on touch screen controller, program enters rotation and handles subprogram, and it is identical that its program circuit is handled subprogram with lifting.
Those skilled in the art do not break away from essence of the present invention and spirit, can there be the various deformation scheme to realize the present invention, the above only is the preferable feasible embodiment of the present invention, be not so limit to interest field of the present invention, the equivalent structure that all utilizations description of the present invention and accompanying drawing content are done changes, and all is contained within the interest field of the present invention.
