Automatic control method of compressed air foam fire extinguishing system, computer equipment and readable storage medium

The invention discloses an automatic control method for a compressed air foam fire extinguishing system. The control method comprises two control modes including a CAF mode and a pure water mode. In the CAF mode, the compressed air foam fire extinguishing system provides a compressed air foam fire extinguishing medium with certain flow and pressure to the outside; in a pure water mode, the compressed air foam fire extinguishing system provides fire fighting water with certain flow and pressure to the outside as a fire extinguishing medium. Automatic switching between the two modes is achieved according to the remaining amount of foam liquid, meanwhile, a CAF pure water mode change-over switch is arranged, and one-key switching between the CAF mode and the pure water mode can be achieved through the mode change-over switch. The continuous fire extinguishing time of the compressed air foam fire extinguishing system can be effectively prolonged, the situation that equipment is forced to stop due to lack of foam
