Discharge type electronic sending device

Abstract

The invention discloses a discharge type electronic sending device, which comprises a charging circuit, a rechargeable battery, a flash lamp circuit, a sounding circuit and a luminous tube indicating circuit, wherein the output end of the flash lamp circuit is connected with a flash lamp, the output end of the sounding circuit is connected with a horn, and the output end of the luminous tube indicating circuit is connected with a light-emitting diode; the flash lamp circuit, the sounding circuit and the luminous tube indicating circuit are respectively connected with the rechargeable battery through normally-open contacts of a linked switch; and the sounding circuit is electrically connected with the horn through normally-closed contacts of the linked switch, and the flash lamp circuit is electrically connected with the flash lamp through the normally-closed contacts of the linked switch. The discharge type electronic sending device has the advantages of simple structure, convenience in manufacture and use and no smoke, is favorable of environmental protection, and is not influenced by the ambient temperature and humidity. The conditions such as dumb guns and bullet buckling are avoided, the game progress is accelerated, and the safety, the reliability and stability in competition events of sports are increased.

Description

technical field [0001] The invention relates to a starting device used in sports, in particular to an electronic starting device suitable for sound and light signaling in competitions. . Background technique [0002] For a long time, in the track and field competition in minor sports, the start is an indispensable link. The starting equipment used to start the race is a gunpowder-type starting gun that emits sound and light signals when fired with gunpowder. The starter fires the gun in front of the smoke screen at the starting point, and the timekeeper at the finish line starts the stopwatch timing after seeing the white smoke produced by the explosion of the starting bomb. , and the athletes started running when they heard the sound of the starting bomb exploding. Although this starting gun is simple and feasible, it has insurmountable defects. For example, gunpowder itself is a flammable and explosive dangerous product, which often causes accidents, which brings great ...

AI Technical Summary

Problems solved by technology

Although this starting gun is simple and feasible, it has insurmountable defects.

For example, gunpowder itself is a flammable and explosive dangerous product, which often causes accidents, which brings great troubles to production and transportation; secondly, because gunpowder is easy to be affected by moisture, it is easy to cause dumb guns to appear when starting the order, which directly affects the athlete's performance. Emotions and the normal progress of the game; moreover, the gunpowder-type starting gun needs to be replaced every time the gunpowder is fired, which is inconvenient
