The tag detector 15 reads information on the radio waves transmitted from the dedicated IC tag 17a, and the tag detector 15 counts the number of safety shoes 17 to determine how many safety shoes 17 are present (step S13). If the number of safety shoes 17 is equal to or more than one pair in step S13, the tag detector 15 receives radio waves transmitted from the dedicated IC tags 18a attached to the helmets 18 corresponding to the number of persons, and reads the information. It is determined whether the helmets 18 are aligned (step S14). Next, the tag detector 15 receives the radio wave transmitted by the dedicated IC tag (not shown) attached to the safety rope (not shown) for the number of people, reads the information, and has the safety rope for the number of people. It is determined whether or not (step S15). When there are one or more safety shoes 17 as safety protective equipment, the information of the dedicated IC tags 18a of the helmets 18 for the number of persons and the information of the dedicated IC tags of the safety ropes for the number of people are gathered. Then, it is detected that the conditions of the tag detector 15 are satisfied and the conditions for manual operation in the elevator pit 11 are met, and the manual operation in the pit is permitted (step S16). In addition, it is necessary when the safety shoes 17 are zero in step S13, when the helmets 18 for the number of people are not prepared in step S14, or when the safety ropes for the number of people are not prepared in step S15. It is determined that all information on safety shoes, helmets, or safety ropes, which are safe safety equipment, is not available, and manual operation in the elevator pit 11 is disabled (step S17).
In the second embodiment, the safety shoes 17, the helmet 18, and the safety rope are given as examples of the safety protection equipment that the maintenance worker 16 should wear on the body. However, other safety protection equipment may be added. . Further, the number of maintenance workers 16 in the elevator pit 11 can be detected by image analysis using a known camera or the like before the number of safety shoes 17 is counted and the number of people is known. If the camera is used, it is possible to detect whether the safety shoes 17 are actually worn, whether the helmet 18 is worn, and whether the safety rope is attached to the body.
