Technical Field

The invention relates to the technical field of door locks, in particular to an intelligent lock anti-interference method and an intelligent lock.

Background

Compared with the traditional mechanical lock, the intelligent lock is far higher than the traditional mechanical lock in the aspects of manageability, safety, convenience and the like. The intelligent lock is unlocked by using non-mechanical keys such as an electromagnetic card, a radio frequency card, fingerprint identification, iris identification and the like, so that the safety of the door lock is greatly improved, and the intelligent lock is widely applied to places such as banks, government departments, hotels, school dormitories, residential quarters and the like.

Although the security of the smart lock is greatly improved on the basis of the traditional mechanical lock, some interference signals, such as interference electromagnetic waves generated by a tesla coil, may interfere with the smart lock, thereby causing the smart lock to be unlocked abnormally, and therefore, the security of the smart lock in the prior art still needs to be improved.
