400m standard track and field track line crossing foul detector

Abstract

The invention discloses a 400m standard ground track field lane line side-stepping detector belonging to the field of sports instruments. An electromagnetic sensor and an electromagnetic distance meter are connected with a multifunctional electronic counter in series through conducting wires to form a closed circuit; a starting end and a terminal end are respectively connected to the outer edge of a lane line and the integrated circuit chip of a programmable control fieldbus through the conducting wires; the outer edge of the lane line, the inner edges of the integrated circuit chip of the programmable control fieldbus and the lane line and the circumstance from the middle to the edge of a pressure sensor are all filled with magnetic powder; a magnetic powder clutch and the inner edge of the lane line are connected with the pressure sensor through the conducting wires which are connected in series to form the closed circuit; the starting end and the terminal end of the closed circuit are respectively connected to the outer edge of the lane line and the integrated circuit chip of the programmable control fieldbus; an electrified conducting wire is fixed above the middle of the magnetic powder; and the starting end and the terminal end of the electrified conducting wire are connected to the outer edge of the lane line and the integrated circuit chip of the programmable control fieldbus.

Description

technical field [0001] The invention relates to a 400-meter standard track and field field crossing line violation detector, which belongs to the field of sports instrument detection equipment. Background technique [0002] In track and field competitions such as 200m, 400m, 400m hurdles, 800m, 4x100m, 4x400m and other events, athletes often step into the outer edge of the inner lane and cause fouls, and referees can only use naked eyes or cameras to judge whether athletes have fouled or not. There are often subjective ideas or cheating behaviors, and even human factors that prevent athletes from performing their sports performance normally. The 400-meter standard track and field field line crossing foul detector can accurately judge whether athletes have violated the line outside the 400-meter standard track and field line or step into the inner line, and play an objective and accurate role in athletes' sports performance. Purpose. The 400-meter standard track and field f...
