Intelligent building automatic control system with fault prediction

An intelligent building automatic control system for predicting failures of facilities based on the operational state of facilities used in buildings and the like,

• wherein the building automatic control system includes a central control unit;
• the central control unit is connected via a communication network to a facility controller that displays the current and voltage supplied to the facility and monitors its operational state, as well as multiple sensors for detecting the operational state of each facility;
• the sensors include a static pressure sensor for measuring the static pressure of a fluid and a dynamic pressure sensor for measuring the velocity head of a fluid;
• the central control unit calculates an operational state coefficient, which is the ratio of the energy supplied to the facility to the operational energy of the facility, and when the operational state coefficient is equal to or less than a reference operational state coefficient, it predicts that the facility will fail and generates a failure prediction message to notify the user;
• and the operational state coefficient is calculated based on the integrated value of electric power obtained by integrating the current and voltage supplied to the facility and the integrated value of changes in static pressure and velocity head of the fluid.
