초록 ▼

The present invention relates to a diagnostic system for use in a network control system. The diagnostic system is preferably utilized to analyze HVAC system or VAV box performance in an environmental control system such as a network facilities management system. The diagnostic system advantageously records temperature, air flow, and actuator position data in the controller associated with the VAV box and calculates an exponentially weighted moving average value. The exponentially weighted moving average value may be related to error values, process output values, change in actuator position, actuator position, duty cycle of the actuator, or starts, stops and reversals of the actuator. Such a system allows a person to analyze VAV boxes and controller performance over a particular timely period and the lifetime of the system. Box and damper warnings may be provided by the diagnostic system when the EWMA values are over or under particular threshold values. The EWMA values are advantageously calculated and stored in the individual controllers.

대표청구항 ▼

A VAV controller operatively associated with a VAV box, said VAV controller coupled to a first communication bus, said VAV controller comprising: parameter input means for receiving a parameter value from a sensor; a communication port coupled with said first communication bus; memory means for storing diagnostic information; and processor means coupled with said memory means, said parameter input means, and said communication port, for generating said diagnostic information and receiving said parameter value, and said processor means programmed to receive said parameter value at said parameter input, said processor means programmed to generate said diagnostic information, said diagnostic information being related to an exponentially weighted moving average error associated with said parameter value, said processor means programmed to provide said diagnostic information to said communication port, wherein a computer is responsive to the diagnostic information provided to said communication port via said first communication bus.
