Photo-communication based unlocking method, electronic lock and electronic key

Abstract

An embodiment of the invention provides a photo-communication based unlocking method, an electronic lock and an electronic key. The method comprises steps as follows: if the electronic key is matchedwith the electronic lock, an optical signal corresponding to any one secret key in a preset secret key pool is taken as a pre-unlocking signal to be sent to the electronic key; an unlocking signal sent by the electronic key according to the pre-unlocking signal is received, the unlocking signal and the pre-unlocking signal are subjected to matching, and if the matching succeeds, the unlocking operation is executed; the electronic key and the electronic lock share the preset secret key pool, the preset secret key pool is a secrete key set containing multiple secrete keys, and the unlocking signal is the optical signal corresponding to the secrete key which is selected from the preset secrete key pool by the electronic key. With the adoption of the method provided by the embodiment of the invention, the condition of unlocking by criminals after the key is lost or stolen can be effectively prevented, and the defects that a smart lock applicable range is limited to individuals and a smartlock is easily distributed by external conditions are overcome.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of dynamic intelligent combination locks, in particular to an optical communication-based unlocking method, an electronic lock and an electronic key. Background technique [0002] At present, there are mainly two types of coded locks circulating on the market: the first is electronic coded locks, which have the advantages of low cost and strong anti-interference ability, but electronic coded locks basically use a fixed keyboard type, so that users can The concealment is low during operation, and it is easy to be seen or secretly photographed, so that the password is easy to be stolen, and the security performance is low. The second is smart locks (such as fingerprint identification, facial recognition, IC card identification), but this type of combination lock is often suitable for boxes, cabinets or rooms with high confidentiality requirements and only used by a small number of people....
