Abstract
Description
Technical Field
[0001] This invention belongs to the field of electronic circuit technology, specifically relating to a novel target hit detection trigger device. Background Technology
[0002] Target mannequins are one of the most commonly used pieces of equipment in shooting training. The hit detection trigger device on the mannequin collects information about bullets striking it, converts this information into hit data, and transmits it to the main controller. The mannequin simulates a real target, including human form and posture, providing a realistic and visual target for shooting training. Shooters can treat it as a target in actual combat and conduct targeted shooting practice.
[0003] Currently, target detection triggering devices on the market based on traditional switch signals cause a momentary short circuit at the point of impact when a bullet hits the target. This impact signal is then transmitted to the main controller via a cable. However, the impact point on the target is easily affected by external factors, such as stone splashes, airflow, and unstable target posture, resulting in false alarms due to loose connections or short circuits. Furthermore, there is also the phenomenon of no target alarm when a bullet hits the target cable or the impact signal fails to be transmitted, thus reducing the effectiveness of the target detection device.
