AUTOMATIC TIMING ADJUSTMENT SYSTEM FOR OCCUPANCY SENSORS |
摘要 |
A lighting control system for a space equipped with lamps for illuminating the space comprises a power circuit for supplying power to the lamps, a controllable switch in the power circuit for turning the lamps on and off, an occupancy sensor for detecting motion within the space and generating a motion-detected control signal in response to the detection of such motion, and a timer for measuring a time-out interval following the generation of the motion-detected control signal by the occupancy sensor and producing a time-out control signal in response to completion of the measurement of the time-out interval. A processor receives the control signals from the occupancy sensor and the timer and produces a switch-off control signal for the controllable switch to turn the lamps off in response to the time-out control signal, modifies the time-out interval by a time-out offset value in response to preselected events, counts the number of times the switch-off control signal is produced, without the receipt of the motion-detected control signal, within a predetermined time following the end of the time-out interval, and decrements the time-out interval by the offset value in response to the count reaching a predetermined value. |
