Sensing method for collecting multivariate information at a goaf side based on chutes of scraper conveyors

A sensing method for collecting multivariate information at a goaf side of chutes based on scraper conveyors comprising:

• analyzing common mode difference features in changing processes of chutes of a scraper conveyor and providing at least one gesture sensor for the chutes at a goaf side of the chutes;
• building an equivalent model based on the chutes, fusing constants and variants of relative distances, and determining collection of multivariate information and a plurality of combinational logic algorithms of detection bodies of the at least one gesture sensor of the chutes;
• sensing gesture changes of the chutes via the at least one gesture sensor of the chutes, and conducting collection of the multivariate information;
• judging whether relative movements are present in between the chutes based on the multivariate information collected by the at least one gesture sensor of the chutes;
• where the relative movements are present, turn to step S105;
• where the relative movements are not present, turn to step S103;
• and
• judging trends of the relative movements and judging directions and magnitudes of the relative movements, determining corresponding points and conducting information interaction;
• meanwhile generating mapping images of relative positions of the chutes.
