no. 1 Embodiment approach

[0018] Fig. 1 is a diagram showing a configuration of an elevator abnormality diagnosis system according to a first embodiment of the present invention.

[0019] A car 12 is connected to one end of a 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 move 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 car 12 is performed by a control panel 15 installed in a machine room or the like. The control panel 15 is constituted by a general-purpose computer having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. In addition, lead wires 16 are 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 the like are performed...

no. 2 Embodiment approach

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

[0063] Fig. 8 is a diagram showing a configuration of an elevator abnormality diagnosis system according to a second embodiment of the present invention. In addition, the same code|symbol is attached|subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the description is abbreviate|omitted.

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

[0065] The data collection part 21 collects the data of each apparatus from each control panel 15 of elevator 10a, 10b, 10c at a predetermined cycle. In addition, the data collection period for collecting the data of each device ma...

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 abnormalities of various equipment such as elevator doors and traction machines. Background technique [0002] Elevators play an important role as vertical transportation equipment, and when they cannot be used due to malfunctions, it will cause great trouble to guests. Therefore, it is important to constantly monitor the status of elevators to prevent failures before they occur. [0003] Conventionally, as an apparatus 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 device and a management unit (monitoring center). On the side of the elevator control device, an inspection device for inspecting an abnormality of the elevator is provided. On the side of the management unit, a function of collecting and processing data from the inspection devi...
