Problems solved by technology

However, if the threshold is lowered, even elevators that are not yet in trouble will be judged as abnormal, resulting in an increase in the number of dispatches of maintenance personnel
On the other hand, if the threshold is raised, the number of dispatches of maintenance personnel will decrease, but the state of poor ride quality will remain, which is not conducive to ensuring good service

[0018] figure 1 It is a schematic diagram showing the structure of the elevator maintenance system according to the first embodiment of the present invention.

[0019] One end of the main rope 11 of the elevator 10 is connected to the car 12 , and the other end is connected to the counterweight 13 . When the hoist 14 is driven, the car 12 and the counterweight 13 run in a bucket type (つるベ type) in the hoistway through the main cable 11 wound on the sheave of the hoist 14 .

[0020] The car 12 is composed of a compartment 15 on which passengers ride, and a car frame 16 supporting the compartment 15 . The box chamber 15 is supported by the car frame 16 through the anti-vibration rubber 17 provided on the lower part thereof. A load gauge 18 connecting the box room 15 and the car frame 16 is installed on the bottom of the box room 15 . The load gauge 18 calculates the load load of the housing 15 based on the relative displacement between the housing 15 and the car frame 16 in t...

[0055] Next, a second embodiment of the present invention will be described.

[0056] The configuration in the above first embodiment is to adjust the parameters through the change of the load data under the condition of no load. In contrast, in the second embodiment, parameter adjustment is performed based on load changes after the start of operation.

[0057] Figure 4 is a schematic diagram showing the configuration of the elevator maintenance system according to the second embodiment of the present invention. Also, for the drawings and the aforementioned first embodiment figure 1 The same components are denoted by the same symbols, and their descriptions are omitted here.

[0058] In the second embodiment, a load fluctuation storage unit 38 is added to the abnormality monitoring control device 30 . The load variation storage unit 38 stores the load variation Fr immediately after the operation is started. The adjustment unit 35 performs parameter adjustment when the ab...

Abstract

The invention relates to an elevator maintenance system. The elevator (10) side is equipped with an abnormity monitoring controller (30), which collects action data of a monitoring object machine collected by a data collection part (31), and saves the data in the current data storage part (33). A calculation part (34) calculates the differential value between an initial data saved in an initial data storage part (32) and a current data saved in a current data storage part (33). A regulation part (35) has a first threshold value set by the upper limit of the monitoring object machine, and a set second threshold value lower than the first threshold value. When the differential value exceeds the second threshold value, the preset parameter is adjusted and the action data is changed, thereby reducing the absolute value of the differential value of the action data for continuous operation.

Description

technical field [0001] The invention relates to maintenance systems for elevators. Background technique [0002] Elevators play an important role as vertical transportation equipment, and if they cannot be used due to a breakdown, it will cause great trouble to the passengers. Therefore, it is very important to monitor the state of the elevator in real time and prevent failures. [0003] Conventionally, there is, for example, an elevator management system disclosed in Japanese Patent Publication No. 3016933 (hereinafter referred to as Patent Document 1) as a system for monitoring the state of an elevator. The management system is composed of elevator control device and management department (monitoring center). The elevator control device side is equipped with a detection device for detecting elevator abnormality, and the management part side has the function of collecting and processing data from the detection device. [0004] In order to prevent elevator equipment failu...
