To scientific research, the extensive concern of medical science all circles.
At present, the mode that slice scanner transports section is using step motor control push rod, and section is stored from section
It is pushed in container (box of cutting into slices) on slide glass platform；After the completion of scanning, recycle hook to cut into slices from slide glass platform and retract
Into section storage container.
The operation principle of stepper motor is as follows：The distance * that pushrod movement actual range=motor fortune turns around is sent out to motor
The umber of pulse sent, when section from section box falls back on the section of section platform by push rod, to be put into the distance of groove be L, and stepper motor operates
The distance of one circle is X, now umber of pulse n=L/X；In the case of theory, as long as computer control terminal sends n umber of pulse, section
It is put into regard to section can be shifted onto from section box completely in groove；But in practical operation, although computer control terminal have sent n pulse
Number, but progress due to stepper motor or section meet obstructions and are not completely pushed to section and are put into groove, are moved when having performed this
After work, when carrying out subsequent action again due to not arriving desired location, fragment of cutting into slices can be caused.
Due to a variety of causes be present, cause section can not normal load.L such as can not be accurately calculated, so as to cause umber of pulse n
Deviation；As error be present in actual motion, cause the distance that L can not be reached by n pulse；Section can not correctly be judged whether
In place, when causing to carry out next action, section is broken.
Therefore, need badly and a kind of can interpolate that section whether completely in place and a kind of section for whether moving into place of section is swept
