The invention relates to a code anti-stealing technology of an electronic coded lock, which can effectively prevent the code of the electronic coded lock from being stolen. The code anti-stealing technology of the electronic coded lock uses 20 sets (three groups per set) of codes. An anti-stealing mechanism is described as follows: after an electronic lock sends a certain group (excluding the last group) of codes to a key, the electronic lock does not confirm the next group of codes sent by the key or does not receive the next group of codes within set time, the electronic lock keeps noneffective setup of the set of codes before sending a certain group (excluding the last group) of codes to the key, and then the electronic lock exits from an unlocking procedure.
Description
technical field [0001] The invention relates to an electronic combination lock. Background technique [0002] There is no password anti-theft technology of electronic combination lock at present. Contents of the invention [0003] The password anti-theft technology of the electronic combination lock can effectively prevent the password of the electronic combination lock from being stolen. [0004] Present electronic combination lock, because electronic combination lock and electronic key all do not have effective password anti-theft technology, so can't be promoted. [0005] The password anti-theft technology of this electronic combination lock uses 20 sets (3 groups of each) of passwords. [0006] 20 sets of passwords are A 1 , B 1 、C 1 、A 2 , B 2 、C 2 ,...A 20 , B 20 , and C 20 . [0007] A 1 , B 1 , and C 1 It is the first set of password (the default unlock password). [0008] A 2 , B 2 , and C 2 It is the second set of passwords (when the first set ...
