Delayed explosion fire extinguishing bomb and control method thereof

Abstract

The invention relates to a delayed explosion fire extinguishing bomb and a control method thereof, the delayed explosion fire extinguishing bomb comprises a fire extinguishing bomb and a delay control system, and the delay control system comprises an airborne control subsystem, a bomb-borne execution subsystem and a ground monitoring subsystem; the airborne control subsystem comprises a main control module, a dual-mode distance measurement module, a missile-borne interface module, a wireless communication module and a mechanical connection module, the dual-mode distance measurement module integrates a laser radar unit and a millimeter wave radar unit, and self-adaptive switching is achieved through an ambient light sensor; the missile-borne execution subsystem comprises a missile-borne control module, a super-capacitor power supply module, a detonation execution module, a state detection module and a dual-safety insurance module, and the dual-safety insurance module comprises a mechanical safety cap and software dual-instruction verification; a dual-mode radar fusion design is adopted, automatic switching is performed according to visibility, and the ranging failure probability under complex meteorological conditions is effectively reduced; and compared with a single radar scheme, the precision is improved, and it is ensured that the fire extinguishing bomb accurately falls into a fire point core area.
