Automatic test method and test system for elevator car accidental movement protection

Abstract

The invention provides an automatic testing method and system for unintended car movement protection of an elevator. The automatic testing method comprises the following steps that testing parameters and a testing starting command which are input by a user through a handheld operator are received, and an automatic testing starting request is sent according to the testing starting command, wherein the testing parameters include the operating parameter and the design parameter; after the request is received, the elevator operating environment is initialized and is made to meet the unintended car movement protection testing condition; after initialization is completed, a car is controlled to be subjected to relevant testing according to the operating parameter, and all actions of the elevator in the testing process are recorded and displayed in real time through the handheld operator; and after relevant testing is completed, position data when the car is in a static state are obtained and a measurement result is generated, a testing result is obtained by combining the measurement result with the design parameter and fed back to a user through the handheld operator. The automatic testing method and system for unintended car movement protection of the elevator have the advantages that the testing method is simple, the testing result is reliable, and repeated testing can be achieved.

Description

technical field [0001] The invention relates to the technical field of elevator safety detection, in particular to an automatic testing method and testing system for accidental movement protection of an elevator car. Background technique [0002] Unintended car movement protection (UCMP) is defined as: in the unlocked area, when the landing door is not locked and the car door is not closed, due to the drive host or drive on which the safe operation of the car depends The failure of any single component of the control system causes the unexpected movement of the car away from the landing, and the lift shall have a device to prevent or stop the movement. According to the national standard, when the elevator system is equipped with door opening and re-leveling functions, the elevator must provide car accidental movement protection. [0003] For the test of car accidental movement protection, each elevator manufacturer implements different test methods, mainly simulating variou...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problem in the prior art that the automatic testing process of the elevator car accidental movement protection cannot be monitored in real time, the elevator car accidental movement protection automatic testing method and system provided by the present invention can monitor the elevator car accidental movement protection automatic testing process in real time And after the test is completed, you can directly obtain the test results used to judge whether the elevator meets the UCMP test. The test method is simple, the test results are reliable, and the test can be repeated many times.
