Abstract

The invention relates to an electronic device for training a grenade, which comprises a release safety switch, a power switch, a piezoelectric trigger circuit, a time delay circuit, a self-destruction time circuit, an OR gate, two AND gates, a starting signal transmission circuit, a transmitting antenna, a receiving antenna, a starting signal receiving circuit, an explosion sound simulation circuit transcribed by a speech chip, a loudspeaker, an explosion sound transmission circuit, an explosion sound receiving circuit, an accidentally drop safety circuit and the like. When the grenade touches down or bursts in air in a time delay way, the receiving circuit outside the grenade receives a starting signal transmitted by the transmission circuit on the grenade, a speech chip circuit is started after demodulation, and explosion sound is sent out by the loudspeaker. When the grenade touches down or bursts in the air in the time delay way, the explosion sound which is transmitted on the grenade and is already transcribed on the speech chip of the explosion sound simulation circuit in advance is demodulated and amplified by the receiving circuit outside the grenade. The invention is also provided with the accidentally drop safety circuit and achieves the effect of lifelike simulation.

Description

technical field

[0001] The invention relates to an electronic device of a training apparatus, in particular to a hand grenade electronic device for military training. Background technique

[0002] In modern military training, if live ammunition is used, casualties are often caused, and the cost is relatively large. The electronic device for training grenades is designed according to the needs of the troops.

[0003] At present, the known military training simulation grenade devices mainly include the training paper grenade successfully developed by Yuan Fenglei, a professional sergeant of a training regiment of the Second Artillery Corps in China. The "shrapnel" flying out of the explosion does not hurt people (http: / / www.sina.com .cn2000 / 04 / 28 Science and Technology Daily). Its shortcoming is that the ignition mechanism of this kind of training grenade is ignited by pulling the fuse, and it can only be used once. There is no fail-safe safety circuit, and the air shock wave...
