Problems solved by technology

[0007] In the elevator door safety device disclosed in the above-mentioned patent document 1, since it is necessary to set a special rotating rod-shaped detector on the elevator car door, and make the The rod-shaped detector rotates between the elevator car door and the elevator hall door, so it is necessary not only to provide the necessary gap between the elevator car door and the elevator hall door, but also in case fingers, etc. are inserted into the closing side end of the elevator door, etc. , it may also happen that the finger is hit by the rod detector and the finger is injured
In addition, in the solution of Patent Document 2, the rope-like object is detected as the elevator car moves up and down, so in case the detection by the detector fails, the elevator will go up and down while holding the rope-like object question
In addition, in the control system of Patent Document 3, the pet owner or the like presses the special button instead of detecting the pet leash, so that safer control can be performed. In addition to adding trouble and burden to pet owners, there are also problems that the function cannot be effectively used when the pet owner forgets to operate.

Abstract

The invention provides a method for controlling an elevator capable of detecting rope-form objects actually in non-contact manner and judging whether a closing action of the elevator door is possible. The elevator door 1 is provided with a reader (3) of IC mark (10) for detecting the IC mark (10) on the rope-form object (6). The elevator door (2) is made to be closed when the reader (3) confirms that the rope-form object (6) has entering the elevator door (1) completely.

Description

technical field [0001] The invention relates to an elevator control method, which judges whether the elevator car door can be closed by detecting whether the object connected with the rope-shaped object has entered the elevator car together with passengers. Background technique [0002] As a general elevator control method, it is mostly controlled so that when the elevator doors are closed, if someone or an object is caught between the two elevator doors or between the elevator doors and the side panels, the safety boots installed on the elevator doors After detecting that someone or an object is caught, the elevator door is reopened. However, if there is a very thin rope-like object caught between the elevator doors, the detector may not be able to detect the thin rope-like foreign object due to detection blind spots. For example, when an elevator passenger and a pet tied to a pet leash get into the elevator or get off the elevator together, if the pet owner and the pet ar...
