Current-induced elevator operation data acquisition system and acquisition method thereof

Abstract

The invention relates to a current-induced elevator operation data acquisition system and an acquisition method thereof. The system comprises a traction machine, a traction wheel, an electric induction module and an elevator control module; the electric induction module comprises a permanent magnet group, a conductive coil and a current monitoring module, and the conductive coil is electrically connected with the current monitoring module; the permanent magnet group or the conductive coil is arranged on the traction wheel and rotates along with the rotation of the traction wheel, so that the conductive coil cuts a magnetic induction line to generate a corresponding electric signal; and the elevator control module is electrically connected with the current monitoring module and calculates the rolling stroke and/or the rolling speed and/or the forward and reverse rotation of the traction wheel according to the electric signals fed back by the current monitoring module, and then the running distance and/or the running speed and/or the ascending, descending and/or stopping position of a lift car are/is correspondingly obtained. The elevator running data can be effectively collected, data are accurate, performance is reliable, and the current-induced elevator operation data acquisition system can be universally used for elevators of different models.

Description

technical field [0001] The invention relates to an elevator auxiliary device, in particular to a current-sensing elevator running data collection system and a collection method thereof. Background technique [0002] Collecting the running data of the elevator helps to monitor whether the elevator is running safely. Generally, the running data that needs to be collected includes running information, running direction, position information, car running speed, etc. The collected running data will be sent to the control center for centralized Control management and monitoring, so that the control center can control the normal operation of the elevator according to the operation data or take corresponding measures in time in abnormal / emergency situations. [0003] At present, the elevator is generally controlled by RS485 or CAN BUS in the elevator control system, and the running data is displayed on the corresponding floor and car; when obtaining the running status information of...

AI Technical Summary

Problems solved by technology

[0003] At present, the elevator is generally controlled by RS485 or CAN BUS in the elevator control system, and the running data is displayed on the corresponding floor and car; For information, various technical means are usually used to connect with the elevator controller, and to read and collect the car running status information; however, there are different types and types of elevators on the market, and the communication protocols used by different elevators often have Therefore, to read the elevator running status information from the elevator controllers of different types of elevators, it is necessary to know the communication protocol and elevator parameters of the relevant elevator models. Remote monitoring management provides standard communication data related to elevator operation status information; in addition, the current collection method of elevator operation data in the market generally adopts contact detection scheme, which not only affects the accuracy of operation data collection, but also may interfere The normal operation of the elevator; in addition, directly reading the elevator operating status information from the elevator controller means relying on the status of the elevator controller. When the elevator controller fails, it cannot continue to provide reliable elevator operating status information
