FAILURE SIGN DIAGNOSIS SYSTEM AND FAILURE SIGN DIAGNOSIS METHOD FOR DOOR SYSTEM

To enable a failure sign diagnosis of a whole door system including not only a drive part of each door but also a management part, a communication device, etc.SOLUTION: A failure sign diagnosis system for a door system having a management unit for instructing an opening/closing timing to a plurality of opening/closing devices for controlling the opening/closing of each of a plurality of doors includes a data input unit for inputting information relating to the opening/closing time of each of the plurality of doors, a storage unit for storing the information relating to the opening/closing time of each of the plurality of doors including the past time, and a failure sign diagnosis unit for comparing the information relating to the opening/closing time with the information relating to the opening/closing time including the past time, diagnosing that there is a failure sign in the opening/closing devices of some of the doors when the opening/closing time of some of the doors is different from the past opening/closing time, and diagnosing that there is a failure sign in the management unit when the opening/closing time of all of the plurality of doors is different from the past opening/closing time.SELECTED DRAWING: Figure 1 【課題】各ドアの駆動部だけでなく、管理部や通信装置などを含めたドアシステム全体の故障予兆診断を可能にする。【解決手段】複数のドア個々の開閉を制御する複数の開閉装置に対して開閉タイミングを指令する管理部を有するドアシステムの故障予兆診断システムとして、複数のドア個々の開閉時間に関する情報を入力するデータ入力部と、複数のドア個々の開閉時間に関する情報を過去の分も含めて記憶する記憶部と、開閉時間に関する情報と開閉時間に関する過去分も含めた情報とを比較して、複数のドアの内一部のドアの開閉時間が過去の開閉時間とが異なる場合には、一部のドアの開閉装置に故障予兆があると診断し、複数のドア全ての開閉時間が過去の開閉時間と異なる場合には、管理部に故障予兆があると診断する故障予兆診断部を備える。【選択図】図１
