Problems solved by technology
However, there are certain limitations in applying the automatic target reporting technology of shooting targets to the automatic target reporting in grenade throwing training.
The double-layer electrode short-circuit sampling system, that is, the electronic carpet, has a large weight when the shooting range is large, which is not convenient for rapid deployment, and after repeated impacts by training grenades, the circuit is prone to damage and the maintenance cost is high
The photoelectric positioning coordinate technology requires a large number of photoelectric sensors, the installation and use costs are very high, and the flatness of the shooting range is required to be high, the site adaptability is poor, and it is inconvenient for the field mobile training of the troops
The image-based automatic target reporting system needs to calibrate the camera position before it can be used, and in order to obtain higher target reporting accuracy, the camera position needs to be set up at a higher position, the volume is also large, and it is easy to be hit during training and damaged
At the same time, for hard ground, it is difficult to identify the image due to the inability to leave an obvious impact point, while for sandy ground, the recognition difficulty will be higher and the cost will rise sharply

The invention discloses a sound-based throwing object automatic target reporting system and target reporting method. The target reporting system includes a target target, a sound collection node, a wireless network, a wireless gateway node and a system terminal. Locally estimate the landing time of the collected sound, and use the wireless network to achieve high-precision clock synchronization. Each node transmits data to the system terminal through the wireless network, and uses the least squares-based time difference of arrival positioning algorithm to locate effective events. And display, realize the automatic target reporting in the process of throwing training. The target reporting system of the present invention has high adaptability, light portability, fast deployment, strong anti-interference ability, low cost, low power consumption, fast response speed, and high target reporting accuracy, and can improve the informatization degree and training efficiency of the daily training of armed police forces and training effects.
Description
technical field [0001] The invention belongs to the field of location-based services, in particular to a sound-based automatic throwing object system and target reporting method. Background technique [0002] At present, most of the civilian and military automatic target reporting systems at home and abroad are shooting targets for light weapons, and most of them are only suitable for indoor environments. The automatic target reporting system designed for armed police grenade training has not been reported in domestic and foreign media and periodicals, and it is still blank. Different from the automatic target reporting system for shooting targets, the shooting range for grenade training has no fixed targets, usually ground markers or marked areas, and training simulation bullets are used, which cannot leave obvious marks such as bullet craters or bullet holes. At the same time, for hard training grounds, the rebound of the simulated grenade will cause jumping, and the obse...
