Problems solved by technology

However, the propagation speed of electromagnetic waves in different propagation media is different; when the surface of the radar or the surface of the target irradiated object may be contaminated with dust, oil, etc. will change, resulting in inaccurate elevator measurement values, and unable to perform self-diagnosis, resulting in low accuracy of the measured elevator position

Abstract

The invention relates to an elevator measuring data abnormality detection method and device, an elevator detection system, computer equipment and a storage medium. The method comprises the steps thatthe distance measuring value and the received signal intensity measuring value generated when an elevator runs to the set position are obtained, and the distance measuring value and the received signal intensity are measured according to radar arranged on the top or the bottom of an elevator car or arranged on the top or the bottom of an elevator shaft; the received signal intensity reference value corresponding to the set position is obtained, and the difference value of the received signal intensity measuring value and the received signal intensity reference value is determined; the receivedsignal intensity reference value is obtained according to the received signal intensity measuring value measured by the radar during radar initial installation when the elevator runs to each set position; and if the difference value meets the set condition, it is determined that abnormality exists in the distance measuring value. By adoption of the method, the purpose of automatic detection of abnormality of the elevator measuring value is achieved, and the defect about the low measured elevator position accuracy is overcome.

Description

technical field [0001] The present application relates to the technical field of elevator detection, and in particular to a method and device for abnormal detection of elevator measurement data, an elevator detection system, computer equipment, and a storage medium. Background technique [0002] With the rapid development of science and technology, electromagnetic wave distance measurement technology is gradually perfected, and is currently widely used in various distance measurements, such as liquid level measurement, celestial body distance measurement, elevator position measurement, etc. [0003] At present, in the elevator position measurement, there is a method that sends electromagnetic waves to the target irradiation object (such as the top of the elevator shaft) through the radar, and combines the reflected electromagnetic waves and their propagation speeds to determine the elevator position. However, the propagation speed of electromagnetic waves in different propag...
