Abstract

The invention provides an elevator water retreat operation system which can sufficiently suppress water damage to an elevator. According to the invention, the system herein comprises a mobile terminal (25) which is carried by a worker (105) who manages the elevator (101). The elevator (101) includes a wireless communication apparatus (26) which is in communication connection to a control apparatus (24) and conducts wireless communication with the mobile terminal (25). The mobile terminal (25) comprises a starting command generation part (255A) which generates a starting command for water retreat operation. The control apparatus (24) includes a water retreat operation restarting part (243A) which restarts water retreat operation after the lift of water retreat operation which is implemented on the basis of the starting command of the water retreat operation from the operation command apparatus (32) and upon receiving the starting command of the water retreat operation from the mobile terminal (25) through the wireless communication apparatus (26).

Description

technical field [0001] The present invention relates to a submersion avoidance operation system of an elevator that implements a submersion avoidance operation for preventing the elevator installation from being submerged in water. Background technique [0002] Generally, an elevator installed in a building is equipped with various equipment such as an earthquake sensor to detect the shaking when an earthquake occurs, and a door control device to control the operation of the door. Movement is controlled to provide smooth service to passengers using the elevator. [0003] However, the equipment of the above-mentioned elevator is installed in the elevator shaft and the car. Therefore, if the elevator encounters wind and rain such as a typhoon and water enters the elevator shaft, the elevator equipment may be flooded and cannot operate normally. In the above cases, the door cannot be opened and passengers are locked in the car, or the car stops and passengers cannot use the el...
