SMART ENERGY-SAVING POWER SOURCE CONTROL APPARATUS AND METHOD

摘要

The present invention discloses a smart energy-saving power source control apparatus and method. The apparatus includes a sensor set and a system control unit, and the system control unit includes a moving direction determination unit, a timer, a counter, a power switch system control unit. The method includes the steps of: electrically connecting the moving direction determination unit to the direction sensor set to detect and determine the moving direction and the number of persons; defining an initial value for a numeric value of the counter, and setting a set time for the timer; incrementing the numeric value of the counter by one unit if the moving direction determination unit detects the entrance of a person, and starting counting time by the timer; decrementing the numeric value of the counter by one unit if a person exits; turning off the power switch system control unit if the numeric value of the counter is equal to the initial value; turning on the power switch system control unit if the numeric value of the counter is greater than the initial value; compulsorily resetting the counter to the initial value if the time counted by the timer is equal to the set time value and turning off the power switch system control unit, and resetting the timer and stopping counting the time. The apparatus is installed in an indoor space such as a conference room, an office, a research room, a public bathroom or a pantry with one or more exits. The invention automatically controls the switch of power without requiring any manual operation, not only capable of determining whether there is people in a controlled space, but also capable of self-correcting and removing noises to achieve the smart energy-saving effect and improve the convenience and safety of use.
