Air filtration monitoring system with learning features

A monitoring system for an air filtration system comprising:

• a control circuit;
• and
• a pressure sensor, wherein the pressure sensor is in electronic communication with the control circuit;
• wherein the monitoring system is configured to
• operate in a first mode;
• record signals of the pressure sensor while operating in the first mode over a first time period, wherein the recorded signals of the pressure sensor while operating in the first mode over the first time period comprise a first series of valve pulses;
• generate one or more signal templates representing different operational states of a filtration system by processing the recorded signals of the pressure sensor while operating in the first mode over the first time period;
• operate in a second mode;
• record signals of the pressure sensor while operating in the second mode over a second time period that is after the first time period, wherein the recorded signals of the pressure sensor while operating in the second mode over the second time period comprise a second series of valve pulses;
• and
• compare the signals of the pressure sensor obtained at the second time period against the one or more signal templates while operating in the second mode.
