Electronic Control System for Energy Saving in Elevator

The invention discloses an electronic control system for energy saving in elevator. The system comprises of a thermal sensor, relay unit, logic gate unit and a control unit so connected in a logical way to detect the presence of occupant. The individual component of whole system is placed at appropriate position. Thermal sensor detects and reverts to the control unit about the occupancy of passenger within elevator. Combining the presence of the occupant by thermal sensor with other various possibilities of presence of the passenger reverted by other sensors is used as a logical combinations. Upon detection of the absence of passenger as per the logical output, the control unit signals the relay unit which therefore signals the logic gate unit to turnoff the unnecessary fan and electricity.
