Elevator evacuation operation system

Embodiments of the invention relate to an elevator evacuation operation system for fire hazards, specifically to an elevator evacuation operation system which allows people in a building to be rapidly and efficiently rescued when a fire hazard occurs. The elevator evacuation operation system comprises detectors, a load detector and a control part. The detectors are arranged in halls on all floors or in a lift channel to detect the occurrence of fire hazards. The load detector is used to detect loads beyond a common car load permission range. Under the condition that detection signals are already provided by the detector, the control part allows more users to ride an elevator based on the detection signals from the load detector.
