Water and electricity heat tracing heating optimization method, system and equipment for tunnel fire fighting and medium

The invention discloses a water and electricity heat tracing heating optimization method, system and equipment for tunnel fire fighting and a medium, and relates to the technical field of tunnel fire fighting. The method comprises the following steps: acquiring associated data of tunnel fire fighting; the associated data comprises water consumption time, a physical network, environment temperature and temperature of water in the pipeline; constructing a time-environment temperature-in-pipeline water body temperature network model according to the associated data; nodes in the time-environment temperature-in-pipeline water body temperature network model are determined by discretizing water use time; constructing a target function based on a time-environment temperature-in-pipeline water body temperature network model; and an electric heat tracing heating optimization model is constructed according to the target function and the condition constraint, and heating time control is conducted through the electric he
