Elevator car running state recognition system and method

Abstract

The invention relates to an elevator car running state recognition system and method. The elevator car running state recognition system comprises a hoisting rope sensor and a running state recognitioncontrol unit, wherein the hoisting rope sensor collects the running data of an elevator car (J) by monitoring the running state of an elevator hoisting rope, and the running data of the elevator car(J) comprises the running stroke and / or running speed of the elevator car (J); the hoisting rope sensor comprises a fixed pulley and a rotating shaft; a running state recognition control unit is connected with the hoisting rope sensor so as to receive the elevator car (J) running data collected by the hoisting rope sensor and carry out processing and analysis; the running state recognition controlunit comprises a central main control module used for monitoring, analyzing and calculating the running data of the elevator car (J), a memory used for storing related data and a network communication module used for achieving data transmission. According to the system and the method, the running state information of the elevator car (J) can be effectively collected, the related operation state can be identified, and the system and the method can be universally applied to different models of elevators.

Description

technical field [0001] The invention relates to an elevator auxiliary equipment, in particular to an elevator car running state identification system and an identification method thereof. Background technique [0002] During the operation of the elevator, real-time monitoring of the operation status of the elevator is one of the important technical means to ensure the safe operation of the elevator. etc., and then send the information to the control center (the control center includes the supporting control center or the remote centralized control center) for centralized control management and monitoring; especially in areas with strict requirements for the safe operation of the elevator, it is necessary to monitor the operating status of the elevator To implement monitoring and management, it is necessary to obtain elevator operation information in a timely and reliable manner. [0003] At present, in elevators, the common floor signal display and direction signal display ...

AI Technical Summary

Problems solved by technology

[0003] At present, in elevators, the common floor signal display and direction signal display include seven-segment code display, dot matrix display, liquid crystal display, etc. These information are controlled by RS485 or CAN BUS in the elevator control system, and are displayed on the corresponding floor and car. display; when obtaining the car running status information, it usually uses various technical means to connect with the elevator controller, and reads and collects the car running status information; but because there are different models and types of elevators on the market, different The communication protocols used by different types of elevators are often different, so 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 type of elevator, which brings difficulties to read information. , making it difficult for users to smoothly provide the required standard communication data related to the elevator running status information for elevator remote monitoring and management; in addition, directly reading the elevator running 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 operation status information

It can be seen that there is currently no simple and reliable device on the market that can collect and identify the operating status information of different types of elevators.
