Zusammenfassung: | The invention belongs to the technical field of mine safety, and particularly provides a coal mine goaf high temperature detection early warning and fire prevention and extinguishing intelligent collaborative management and control system. In the system, a temperature sensing module is a plurality of groups of distributed armored temperature measurement optical fibers, and the temperature measurement optical fibers are buried in a goaf in a latticed shape in a fixed wiring manner and a movable wiring manner; a signal demodulation module receives a goaf temperature signal monitored by the temperature measurement optical fibers, demodulates and converts the temperature signal based on an optical time domain and Raman scattering, and performs self-calibration on monitored temperature data obtained through demodulation and conversion based on a preset calibration database; a visual early warning module is internally provided with a mining space-time dynamic model of a coal mine, displays space-time distribution o |
