The invention provides a fire patrol and fire extinguishing
system for a
transformer substation and a fire extinguishing method of the fire patrol and fire extinguishing
system. The fire patrol and fire extinguishing
system for the
transformer substation comprises an autonomous positioning navigation
obstacle avoidance unit, a water mist fire extinguishing unit, a walking
control unit, a sensing
control unit and a
power supply unit. Regular patrol is carried out on a predetermined area, and the surrounding environment is scanned through an
infrared double-vision thermal imaging module. When afire is found, a master control module sends out an
alarm signal, analysis is carried out through image data, and a fire scene area and a fire
source area with the highest temperature are determined.If the maximum distance between the fire
source area and the boundary of the fire scene area is smaller than or equal to 1 m, fire source fire extinguishing is executed preferentially. If the maximumdistance between the fire
source area and the boundary of the fire scene area is greater than 1 m,
diffusion-prevention fire extinguishing is executed preferentially, and then fire source fire extinguishing is carried out. When the surface temperature of an object ranges from 30 DEG C to 100 DEG C, fire extinguishing on the area is stopped. After fire extinguishing is completed, patrol continues to be carried out. Through the arrangement, the fire patrol and fire extinguishing system for the
transformer substation has extremely high fire extinguishing efficiency, and meanwhile secondary damageto
electronic equipment cannot be generated in the fire extinguishing process.
