Data collecting device for elevator safety operation estimating and monitoring system

Abstract

The invention relates to a data collector of lift safe-operation evaluation and detection system. It comprises several switching value sensors and several analog quantity sensors related to the safety of lift, a input interface circuit of multi-path switching valve sensor, a input interface circuit of multi-path analog quantity sensor, and a central processing system for judging the accident of the input data of said multi-path switching valve and multi-path analog quantity and storing the data. The invention can collect the safety detection parameters at any time of the full process of operating lift, while the collected parameters are objective to avoid the effect of human factors. Therefore, the invention can be used as the black box in the safe operation of lift, which can supply the condition to detect the hidden danger of lift earlier, and it also provides a device of micro-computer system for the evaluating the safe operation and real-time detecting the lift.

Description

technical field [0001] The invention relates to an elevator safety operation evaluation and monitoring system, in particular, it is a data acquisition device of the elevator safety operation evaluation and monitoring system. Background technique [0002] In the existing technology, the practice generally adopted by the safety operation management system of all elevators in operation in my country is: the quality inspection management departments of various cities conduct an annual inspection of the elevators under their jurisdiction in accordance with the "Contents and Methods of Elevator Supervision and Inspection" formulated by the national quality inspection department. manual inspection. Although the manual inspection has played an important role in ensuring the safe operation of the elevators in transit, the fly in the ointment is: [0003] 1. Only the running status at that time can be checked. Although the running status can reflect the safety index of the entire elev...

AI Technical Summary

Problems solved by technology

[0003] 1. Only the running status at that time can be checked. Although the running status can reflect the safety index of the entire elevator operation process to a certain extent, the inspection time interval is too long, and it is impossible to know the daily running status within a year, and it is difficult to monitor in real time. The role of the elevator is not conducive to early detection and search for potential failures of the elevator

[0004] 2. The manual inspection is affected by the subjective factors of the inspectors, and the inspection results bear the traces of human factors to some extent. No matter in the elevator inspection data collection and safety assessment, the standardization and standardization that are not easy to achieve, nor Conducive to the establishment of a black box for the safe operation of elevators

[0005] 3. Manual fixed inspection is not convenient for computerized evaluation and real-time monitoring of elevator safe operation, and it is not convenient for computerized management and consultation of elevator inspection data. Computerized management system for computerized evaluation and real-time monitoring and elevator inspection data is imperative
