Activation circuit of unmanned aerial vehicle onboard fire extinguisher bomb

Abstract

The invention provides an activation circuit of an unmanned aerial vehicle onboard fire extinguisher bomb. The activation circuit is mainly composed of a primary manual switch protection unit (1), a secondary unlocking protection circuit (2), a time delay circuit (3) and an initiating explosive device activation circuit (4) and other components; the primary manual switch protection unit (1) is a protection unit of the whole circuit; and the secondary unlocking protection circuit (2) adopts an engine start signal as a start signal and has a safety protection function even if a button is erroneously operated. In addition, through an optoelectronic isolator of the circuit, the anti-interference ability of the circuit system can be improved. The time delay circuit (3) achieves precise delay control of the activation circuit through a delay chip. When the primary manual switch protection unit (1), the secondary unlocking protection circuit (2) and the time delay circuit (3) are simultaneously activated, the initiating explosive device activation circuit (4) is started to be connected, and a fire extinguisher bomb warhead can be detonated.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle-borne fire extinguishing bombs, in particular to an activation circuit for unmanned aerial vehicle-borne fire extinguishing bombs. Especially the activation control and safety protection unit of the fire extinguishing bomb. Background technique [0002] If a fire occurs in a high-rise building, because the floor height is too high, fire-fighting equipment such as aerial ladders and elevating vehicles are limited by height, and it is difficult to reach the height of the fire floor. The UAV-borne fire extinguishing system has strong mobility and is not affected by the fire extinguishing height and the surrounding environment. It can solve the world problem that high-rise buildings cannot quickly and effectively extinguish fires. For the UAV-borne fire extinguishing bomb system, the main function of the circuit is to realize the activation control and delay required by the safety protection re...
