no. 1 Embodiment approach

[0018] figure 1 It is a figure which shows the structure of the abnormality diagnosis system of the elevator which concerns on 1st Embodiment of this invention.

[0019] A car 12 is connected to one end of the main hoisting rope 11 of the elevator 10, and a counterweight 13 is connected to the other end. When the hoisting machine 14 is driven, the car 12 and the counterweight 13 are moved in a bucket-like manner in the hoistway via the main hoisting rope 11 wound around the hoisting machine 14 .

[0020] The operation control of the cage|basket|car 12 is performed by the control panel 15 provided in a machine room etc.. The control panel 15 is composed of a general-purpose computer including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. In addition, a lead wire 16 is attached to the lower end of the car 12 . Transmission of control signals between the car 12 and the control panel 15 , power supply to the car 12 , and ...

no. 2 Embodiment approach

[0062] Next, a second embodiment of the present invention will be described.

[0063] Figure 8 It is a figure which shows the structure of the abnormality diagnosis system of the elevator which concerns on 2nd Embodiment of this invention. In addition, for the above-mentioned first embodiment figure 1 The parts with the same structure are assigned the same symbols, and the description thereof will be omitted.

[0064] In the second embodiment, one primary diagnostic device 20 is connected to a plurality of elevators 10a, 10b, and 10c installed in the same building. The primary diagnosis apparatus 20 is provided with a data collection unit 21 , a storage unit 22 , a diagnosis unit 23 , and a communication unit 24 as in the above-described first embodiment.

[0065] The data collection part 21 collects the data of each equipment in predetermined cycle from the control panel 15 of each elevator 10a, 10b, 10c. In addition, the data collection cycle which collects the data of ...

Abstract

The invention relates to an abnormality diagnosing system for an elevator. The elevator (10) side is provided with a primary diagnosing device (20), and a monitoring center (31) side is provided with a secondary diagnosing device (30). At the primary diagnosing device (20), the abnormality diagnosing system collects data of each device and detects abnormal signs, and then sends the data of each device to the monitoring center (31) periodically, and reports the condition to the device detected with the abnormal signs to send the data. At the secondary diagnosing device (30), the abnormality diagnosing system stores the data of each device in a database (34), and predicts the failure period of the device according to the record of the data. If a device close to the failure period is existent, a service man attends the scene, till to the condition that failure does not occur at next maintenance and detection, the service man does not attend the scene to carry out corresponding treatment,so as to reduce the attendance times of service man.

Description

technical field [0001] The present invention relates to an abnormality diagnosis system for diagnosing abnormality of each equipment such as doors and hoisting machines of elevators. Background technique [0002] Elevators play an important role as vertical transportation equipment, and when a malfunction occurs and cannot be used, it will bring great trouble to the guests. Therefore, it is important to constantly monitor the state of the elevator to prevent failures before they occur. [0003] Conventionally, as a device for monitoring the state of an elevator, there is an elevator management system disclosed in Patent Document 1, for example. This management system consists of an elevator control apparatus and a management part (monitoring center). On the side of the elevator control device, an inspection device for inspecting the abnormality of the elevator is provided. On the side of the management unit, a function of collecting and processing data from the inspection...
