Provided are a diagnostic device, a diagnostic system, a remote monitoring system, and a maintenance management system capable of determining an abnormality of a bearing with a simple configuration. A diagnostic device diagnoses the abnormality of a bearing in an elevator system having a first sheave, a motor that rotates the first sheave with a rotating shaft body, and a hoist that supports the bearing of the rotating shaft body, a second sheave, a main rope wound around the first sheave and the second sheave, and a car suspended by the main rope. The diagnostic device is provided with: a rotation angle calculation unit that calculates a total value of rotation angles at which the first sheave rotates; and a determination unit that determines the abnormality of the bearing on the basis of the total value of the rotation angles calculated by the rotation angle calculation unit when the car travels in the specific section.

    提供能够通过简易的结构来判定轴承的异常的诊断装置、诊断系统、远程监视系统以及维护管理系统。诊断装置对电梯系统中的轴承的异常进行诊断,该电梯系统具有具备第一绳轮、用旋转轴体使第一绳轮旋转的电动机以及支承旋转轴体的轴承的卷扬机、第二绳轮、卷绕在第一绳轮和第二绳轮的主绳索以及被主绳索悬吊的轿厢,该诊断装置具备:旋转角计算部,计算第一绳轮旋转的旋转角度的合计值;以及判定部,基于在轿厢在特定的区间进行了行驶时由旋转角计算部计算出的旋转角度的合计值,判定轴承的异常。
