4) the person of awaiting measuring touches forward promotion first flange on pressure touch-sensitive screen with both hands, and first flange drives the slider and slides along the slide bar, and laser range finding probe measuring method specifically is:
if the first flange that promotes passes the proximity switch on the third flange, then when triggering proximity switch, record the distance a that laser rangefinder surveyed, after first flange stops removing, record the distance b that laser rangefinder surveyed, then this person under test's test score this moment is: b-a;
if the first flange that promotes does not pass the third flange, then cancel the data of this time laser range finding probe record, supplementary promotion first flange passes the proximity switch on the third flange simultaneously, when triggering proximity switch, the distance c that records laser range finding probe and surveyed slides first flange to the one end that is close to the person of waiting to survey again, and the person of waiting to survey promotes first flange again, treats first flange stop removal back, records the distance d that laser range finding probe surveyed, then the score of the person of waiting to survey of rening this moment is: d-c;
when the first flange stops moving, the distance measured by the laser ranging probe is based on the data measured by the laser ranging probe when any one of the two pressure touch screens loses pressure;
5) the laser ranging probe installed at the bottom of the sliding block sends measured distance data to the display screen for display, and meanwhile, the voice broadcasting device broadcasts the data.
