UAV-borne fire extinguishing bomb activation circuit

Abstract

The invention provides an activation circuit for unmanned aerial vehicles, which mainly consists of a first-level manual switch protection unit (1), a second-level unlocking protection circuit (2), a delay circuit (3) and a pyrotechnic product activation circuit (4) ) and other components. The primary manual switch protection unit (1) is the protection unit of the whole circuit. The secondary unlocking protection circuit (2) takes the engine starting signal as the starting signal, and has a safety protection function even in case of misoperation of the button. In addition, the photoelectric isolator in this circuit can improve the anti-interference ability of the circuit system. The time-delay circuit (3) realizes the precise time-delay control of the activation circuit through the time-delay chip. When the first-level manual switch protection unit (1), the second-level unlocking protection circuit (2), and the delay circuit (3) are activated at the same time, the pyrotechnic product activation circuit (4) enters the access state, and the fire extinguishing bomb warhead can Detonate.

Description

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