Abstract
In an elevator apparatus, a plurality of storage media are arranged in a hoistway so as to be spaced from one another in a hoisting direction of a car. In the car, reading device that reads information stored in the storage media is mounted. The storage media are arranged in the hoisting direction at intervals different from one another. A safety monitor is configured to: execute an operation for detecting two storage media; measure an interval between the detected storage media based on a signal from movement detector; compare the measured interval between the storage media with stored intervals of the storage media: and to grasp the position of the car by using a result of the comparison and the information of the storage media, when a position of the car cannot be grasped.
Claims14
An elevator apparatus, comprising:
- a car;
- movement detector that generates a signal in accordance with movement of the car;
- a plurality of storage media arranged in a hoistway so as to be spaced from one another in a hoisting direction of the car;
- reading device mounted to the car, that reads individual identification information stored in the plurality of storage media;
- and
- a safety monitor that detects a moving amount and a position of the car by using the signal from the movement detector and monitoring presence or absence of abnormality in an operation state of the car,
- wherein the plurality of storage media are arranged in the hoisting direction of the car at intervals different from one another,
- wherein the safety monitor is configured to store the intervals of the plurality of storage media, and
- wherein the safety monitor is configured to:
- execute an operation for detecting two of the plurality of storage media;
- measure an interval between the detected two of the plurality of storage media based on the signal from the movement detector;
- compare the measured interval between the two of the plurality of storage media with the stored intervals of the plurality of storage media;
- and to grasp the position of the car by using a result of the comparison and the individual identification information of the plurality of storage media, when the position of the car is unable to be grasped.
An elevator apparatus, comprising:
- a car;
- movement detector that generates a signal in accordance with movement of the car;
- a plurality of storage media arranged in a hoistway so as to be spaced from one another in a hoisting direction of the car;
- reading device mounted to the car, that reads individual identification information stored in the plurality of storage media;
- a plurality of members to be detected, which are arranged in the hoistway so as to be spaced from one another in the hoisting direction of the car;
- a position sensor mounted to the car, that detects the plurality of members to be detected;
- and
- a safety monitor that detects a moving amount and a position of the car by using the signal from the movement detector and monitoring presence or absence of abnormality in an operation state of the car,
- wherein the safety monitor is configured to:
- store a distance from a detection position of the storage medium to a detection position of the member to be detected adjacent thereto and position information of the plurality of members to be detected, and
- wherein the safety monitor is configured to:
- execute an operation for detecting the storage medium and the member to be detected;
- measure a distance from the detection position of the storage medium to the detection position of the member to be detected based on the signal from the movement detector;
- compare the measured distance with the stored information;
- and to grasp the position of the car by using a result of the comparison, the individual identification information of the plurality of storage media, and the position information of the plurality of members to be detected, when the position of the car is unable to be grasped.
