Abstract

The invention relates to a monitoring method, device and computer equipment for abnormality of a radar shield, and belongs to the technical field of abnormality monitoring. The method includes: acquiring a radar feedback signal; the radar feedback signal includes any one of the following: a radar signal reflected by a protective cover, a radar signal reflected by a specific object and returned through the protective cover; The signal is compared with a predetermined feedback reference signal to obtain a comparison difference; if the comparison difference is greater than or equal to a preset difference threshold, it is determined that the protective cover is abnormal; and the intensity change of the radar feedback signal is determined Rate, according to the intensity change rate to determine the corresponding type of abnormality. The above technical solution solves the problem that the abnormality of the radar shield cannot be determined in time, which will affect the normal use of the radar. It can detect the abnormality of the radar shield in time, determine the type corresponding to the abnormality, and ensure the normal use of the radar.

Description

technical field [0001] The invention relates to the technical field of abnormality monitoring, in particular to a monitoring method, device, computer equipment and storage medium for abnormality of a radar shield. Background technique [0002] Radar is often required for data monitoring in application scenarios such as elevators. There is often a protective cover installed around the radar. After a long period of use, the material of the radar protective cover outside the radar may change or foreign objects (dust, water vapor, etc.) may be attached to the surface, which may affect the normal transmission and communication of radar signals. take over. [0003] In the process of realizing the present invention, the inventors have found at least the following problems in the prior art: in order to prevent the abnormality of the radar shield from affecting the normal operation of the elevator, the radar shield is often replaced regularly by the staff. However, this method cann...
