1. An operation control method suitable for a fire extinguishing system of a voltage converter station, wherein the fire extinguishing system of the voltage converter station comprises a first foam fire monitor extinguishing system, a second foam fire monitor extinguishing system, and an upper computer control system, the first foam fire monitor extinguishing system comprises a first fire monitor and a first compressed air foam generation subsystem, and the second foam fire monitor extinguishing system comprises a second fire monitor and a second compressed air foam generation subsystem; and the method comprises:
after the upper computer control system receives a sound-light alarm signal, an alarm position signal, and a switch position dividing signal, starting a spray range prediction analysis subsystem for a fixed fire monitor;
determining, by the spray range prediction analysis subsystem for the fixed fire monitor based on an external wind direction and an external wind speed, whether a range of the first and second fire monitors effectively covers an entire area of a converter transformer; and
if yes, starting the first compressed air foam generation subsystem and the second compressed air foam generation subsystem, such that the first fire monitor to which the first compressed air foam generation subsystem belongs and the second fire monitor to which the second compressed air foam generation subsystem belongs are automatically preset, and fixing a remote stand of the first and second fire monitors to extinguish a fire; or
if no, if the first fire monitor does not meet a range requirement, replacing the first fire monitor with a first mobile fire-fighting robot to extinguish the fire; if the second fire monitor does not meet the range requirement, replacing the second fire monitor with the first mobile fire-fighting robot or a second mobile fire-fighting robot to extinguish the fire; or if both the first fire monitor and the second fire monitor do not meet the range requirement, replacing the first fire monitor and the second fire monitor with the first and second mobile fire-fighting robots respectively to extinguish the fire.
