Abstract

The invention relates to an infrared controller for a high-speed motion dry chemical projectile. The infrared controller is suitable for a controlled start of a fire extinguishment mode that the projectile is carried by an unmanned aerial vehicle when a fire disaster occurs in a high-rise building, a forest, a large oil storage tank, an oil pool and other environments. The infrared controller comprises infrared detectors, a printed board, a shell, a shell breaking awl and a switch. Secondary photosensitive infrared detectors are adopted as the infrared detectors. The printed board comprises apower supply circuit, a signal acquisition circuit, a signal amplification circuit, a single chip microcomputer processing circuit and a power output circuit. The shell adopts conical face streamlineddesign, and the three detectors are distributed and installed by 120-degree angles. When the fire extinguishment controller enters a fire area along with high-speed motion of the projectile, a sensorcan sense flame fast, and then a start current is output for the start of the projectile. The effects that the projectile operates at a high speed is suspended in the fire area while the projectile does not penetrate out of the fire area are ensured.

Description

[0001] 1. Technical field [0002] The invention relates to an infrared controller for high-speed moving dry powder fire extinguishing bombs. It is suitable for high-rise buildings, forests, large oil storage tanks, oil pools and other environments where fires occur, and the control start of the fire extinguishing method carried by the drone is adopted. [0003] 2. Technical background [0004] At present, for fires in high-rise buildings, forests, large oil storage tanks, oil pools and other environments, drones are often used to carry rocket launch systems and artillery launch systems to transport fire extinguishing bombs into the fire area for fire extinguishing. Its start-up control is mostly realized by adding a timer and ranging. After laser or microwave ranging, calculate and set the time from launch to start according to the initial velocity of the fire extinguishing bomb. [0005] Due to the high speed of the fire extinguishing bombs, the influence of temperature, wi...
