Fire-fighting control system

A method of controlling a fire-fighting device including a pump, said method comprising:

• receiving a user-requested fluid pressure indicating a desired fluid pressure at a nozzle;
• detecting, by a valve pressure sensor, a fluid pressure of a fluid at a discharge valve that controls fluid flow between the pump and the nozzle;
• detecting, by a nozzle pressure sensor coupled to the nozzle, a fluid pressure of the fluid at the nozzle;
• determining, by a controller communicatively coupled to said valve pressure sensor, an expected fluid pressure differential between the nozzle and the discharge valve based on the fluid pressure detected by the valve pressure sensor at the discharge valve and a machine learning algorithm stored on a memory of the controller;
• controlling, by the controller, operation of at least one of the pump and the discharge valve based on the detected fluid pressure of the fluid at the nozzle and the user-requested fluid pressure in a primary mode of operation to deliver fluid to the nozzle at the desired fluid pressure;
• and
• controlling, by the controller, operation of the at least one of the pump and the discharge valve based on the expected fluid pressure differential and a last received user-requested fluid pressure in a secondary mode of operation when communication between the nozzle pressure sensor and the controller is interrupted.

A controller for use with a fire-fighting device including a pump, said controller comprising a memory having a machine learning algorithm stored thereon, said controller configured for communication with a valve pressure sensor configured to detect a fluid pressure of a fluid at a discharge valve controlling fluid flow between the pump and a nozzle, said controller being further configured for communication with a nozzle pressure sensor coupled to the nozzle and configured to detect a fluid pressure of the fluid at the nozzle, said controller configured to:

• receive a user-requested fluid pressure indicating a desired fluid pressure at the nozzle;
• determine an expected fluid pressure differential based on the machine learning algorithm and the fluid pressure detected by the valve pressure sensor at the discharge valve;
• control operation of at least one of the pump and the discharge valve based on the detected fluid pressure of the fluid at the nozzle and the user-requested fluid pressure in a primary mode of operation to deliver fluid to said nozzle at the desired fluid pressure;
• and
• control operation of the at least one of the pump and the discharge valve based on the expected fluid pressure differential and a last received user-requested fluid pressure in a secondary mode of operation when communication between the nozzle pressure sensor and the controller is interrupted.
