Self-extinguishing fire monitor and method for fire disaster detection and locating

Abstract

The invention discloses a self-extinguishing fire monitor and a method for fire disaster detection and location, belonging to the technical field of fire fighting equipment and aiming to provide a fire monitor capable of automatically determining ignition positions and extinguishing fire when a fire disaster occurs. A thermopile sensor is adopted as a fire disaster locating sensor. The fire disaster locating sensor scans a protected area in an all-round way under the triggering of a fire disaster alarm signal, a CPU (Central Processing Unit) collects the temperature of a scanning spot and records a horizontal rotating angle and a pitching rotating angle of the fire disaster locating sensor corresponding to a data collection point to obtain the temperature distribution condition of the protected area, the CPU analyzes temperature field data on the basis of a known normal temperature distribution fluctuation curve and judges the area with abnormally higher temperature, and then the fire disaster locating sensor carries out pitching scanning at the horizontal rotating angle corresponding to the area with abnormally higher temperature and determines the maximum ignition position. The invention is suitable for fire disaster locating and extinguishing of occasions where the surface temperature of objects is raised when the fire disaster occurs.

Description

technical field [0001] The present invention relates to a fire monitor, in particular to a fire monitor capable of automatically locating a fire site and spraying water to extinguish a fire; it also relates to a method for detecting and locating a fire, specifically using a thermopile sensor to sense thermal radiation to obtain a protected area The method of determining the fire site by analyzing the temperature field data. The invention belongs to the technical field of fire fighting equipment. Background technique [0002] Fires in stadiums, airports and petrochemicals are a worldwide problem in fire fighting. This type of building has a large space, dense personnel, and complex layout, and the fire occurrence rate is extremely high. When a fire breaks out, the intensity of the fire spreads rapidly, it is difficult for people to evacuate, and it is difficult to put out the fire, which is quite harmful. Traditional fire-fighting facilities - fire hydrants can only be ext...
