Problems solved by technology

However, the above two types of coded locks are slightly inconvenient for temporary users of coded locks. Fixed coded locks require a coded lock manager to modify the code at the location of the coded lock after being used by a temporary user; Keys are physically handed over to casual users and returned after use

Embodiment Construction

[0021] Please refer to figure 2 . The data tables that can be used for searching can be paper data tables, electronic devices like calculators that store table data, software or data files running on personal computers or mobile phones, or Internet applications, etc. A form of service provided by remote service. There is a lock mechanism part and a control part in the lock body, wherein the control part is composed of a microprocessor IC1, a non-volatile memory IC2, an input unit such as a numeric keypad and an output LED display IC4 (when applicable), etc., through a Output driver IC5, the controller can control the lock mechanism and alarm IC6.

[0022] The temporary password for unlocking is obtained by looking up the corresponding value code on the data table through the key code obtained each time. With the different key codes each time, the temporary password will be changed accordingly, but for the password lock manager It is said that this change can be obtained by...

Abstract

The invention provides a dynamic coded lock system for acquiring codes by virtue of table look-up. The dynamic coded lock system comprises a lock body and a temporary code generator, wherein a fixed code and a key-value data table of a coded lock are stored in a nonvolatile memory in the lock body; when an electronic lock is used by a temporary user, a key code R is displayed by the electronic lock, a temporary code for unlocking the lock is obtained by finding a corresponding value code X in the data table by virtue of the key code R, besides, the fixed code can be used as a parameter to convert the value code X into the temporary code for use, and the temporary code is calculably changed along the changing of the fixed code or the difference of key codes displayed in each time. Therefore, the temporary code can be calculated by a coded lock manager knowing the fixed code and the data table in the coded lock when the key code is received, and after the temporary code is passed to the temporary coded lock user, the lock can be locked by the temporary coded lock user by virtue of the temporary code in a valid time period.

Description

technical field [0001] The invention relates to a dynamic coded lock system which can obtain codes by looking up a table, in particular to a controller of this type of coded lock. Background technique [0002] At present, there are two types of passwords for existing electronic combination locks: the first category is a fixed password that can be set, and the password is stored in a non-volatile memory. When the password stored in the non-volatile memory is checked and the lock is consistent, the value of the password in the non-volatile memory can also be modified through the password setting, and the password can be updated to enhance security. The second category is the use of electronic keys. Electronic keys can be electronic tags such as various contact or non-contact magnetic cards, IC cards, etc. The electronic tags record the password of the combination lock, which solves the distress of users needing to remember the password. The electronic key can also use a dynam...
