Description

TECHNICAL FIELD

[0001] The utility model relates to infrared sensor technical field, especially a kind of magnetic attraction type infrared sensor for sports timing counting. BACKGROUND

[0002] ‌The timing and counting principle of infrared sensor is mainly based on the emission and reception of infrared rays. Infrared sensor is usually composed of two parts, emitter and receiver. The emitter emits infrared rays, and the receiver receives the infrared signal reflected by the object. When an object passes through, the object will block the propagation path of infrared rays, causing the signal received by the receiver to change, thereby triggering the timing or counting function, for example, infrared sensor used in sports as running timing and pull-up counting.

[0003] ‌The timing principle of infrared sensor: in sports competition, infrared photoelectric timing system is widely used in short-distance running events. When the athlete touches the end line, the infrared light is blocked, and the infrared probe detects the change and outputs an electric signal to the control computer, which stops timing immediately and records the athlete's performance‌. This timing method is simple and fast, but has some limitations, such as the athlete blocking the infrared light with his arm, which may cause timing error‌.

[0004] ‌The counting principle of infrared sensor: in marathon and other long-distance races, infrared induction door or infrared sensor is used to record the time point when the athlete passes. When the athlete passes through the induction door, the infrared sensor detects the block and records the time point, thereby realizing the timing and performance recording of the athlete‌.

[0005] Practical application scenarios of infrared sensor:

[0006] ‌1. Short-distance running competition: In short-distance running competition, infrared photoelectric timing system is widely used. The system includes starting gun, optical timing host and optical probe head and other equipment. After the starting gun sounds, the optical timing host starts timing, and when the athlete touches the infrared light beam at the finish line, the timing stops, and the performance display screen immediately displays the running time of the athlete‌.

[0007] ‌2. Marathon competition: In high-level marathon competition, in addition to using traditional infrared induction door, camera or GPS satellite positioning system is also combined to assist timing. These high-tech devices can record the performance of the players more accurately and quickly, ensuring the fairness and accuracy of the competition‌
