Description

Abnormality determination device and abnormality determination system Technical Field The present invention relates to an abnormality determination device and an abnormality determination system for an elevator. Background For example, patent document 1 describes a spot inspection robot for performing maintenance spot inspection on a sill. Specifically, the spot inspection robot of patent document 1 is configured to be capable of spot inspecting a sill of an elevator door when the robot passes through the sill in order to take an elevator car or to get off the elevator car. Prior art literature Patent literature Patent document 1 Japanese patent application No. 6838684 Disclosure of Invention The abnormality in the elevator also includes an abnormality with low reproducibility such as a display failure of the appearance device. Particularly, in the case of an abnormality with low reproducibility, a large amount of time is required for the operator to confirm the presence or absence of the abnormality, and a large burden is imposed on the operator. In addition, for example, in the spot inspection by the spot inspection robot of patent document 1, whether or not there is an abnormality in the state and operation of the spot inspection object is confirmed by touching, tapping, operating the spot inspection object, or the like. In such spot inspection, it is difficult to spot-inspect an abnormality whose reproducibility is low. Therefore, it is desirable to develop a system capable of automatically checking whether or not there is an abnormality in the appearance equipment of the elevator. The present invention has been made in view of the above problems, and provides an abnormality determination device and an abnormality determination system capable of automatically checking an abnormality of an external device of an elevator. An abnormality determination device of the present invention determines whether or not an elevator is abnormal in cooperation with a robot, wherein the elevator is provided with an elevator control device that controls the operation of each part of the elevator, an appearance device that is provided in a car or at a landing and that includes at least one of an input means and a display means, and an appearance device control unit that controls the operation of the appearance device on the basis of 1 st reception data obtained by receiving operation instruction data transmitted from the elevator control device. The robot has a function of detecting an operation state of the appearance device by the detection unit and generating operation state data indicating the detected operation state, and a2 nd function of acquiring 1 st copy data, which is copy data of the 1 st received data, by communication with the appearance device control unit. The abnormality determination device is provided with a data collection unit that collects operation state data and 1 st copy data, and a determination unit that determines whether or not an external device is abnormal by determining the matching between the collected operation state data and 1 st copy data. Effects of the invention According to the abnormality determination device of the present invention, it is possible to determine whether or not an external device of an elevator is abnormal based on data related to operation instructions acquired from a plurality of communication interfaces and data indicating the operation states of the external devices.
