Embodiment 1

[0017] The combination lock system of the present invention comprises two parts, namely the electronic combination lock part and the management server part.

[0018] The electronic password lock part includes a control unit, an input and output unit, a lock control action unit, a sensing unit, and a power supply unit. The control unit is used to control the input and output of information, calculate and verify the correctness of the unlock password, control the action of the lock control action unit to complete the switch of the lock, and read the feedback signal of the sensing unit to detect various states of the lock. The control unit contains a microprocessor, real-time clock, and non-volatile data memory. The input-output unit includes an input device such as a keyboard and an output device such as a display connected to the control unit by wire or wirelessly. The lock control action unit usually consists of a motor or an electromagnet. The sensing unit is composed of lo...

Embodiment 2

[0027] The electronic password lock part and the management server part of this embodiment are the same as those of Embodiment 1. The initialization of new locks and user registration are the same as those in Embodiment 1.

[0028] In this embodiment, the principles and methods of its control and unlocking are as follows:

[0029] Close the lock: after the lock-off person implements the lock-off operation to the electronic combination lock 80, the microprocessor 111 in the control unit 110 reads the current lock-off time from the real-time clock 113, and records the current lock-off time in the non-volatile data memory In 112, the lock time and the ID number of the electronic coded lock 80 are output to the output device 120 at the same time. The output device 120 may be a display fixedly connected to the electronic combination lock 80 , or a mobile handheld device with non-volatile data memory connected to the electronic combination lock 80 in a wired or wireless manner. If...

Abstract

This is an electronic code lock and its control method. The lock is composed by a central management server and electronic code lock. The server generates an unlock code after coding related information like allowed unlock time; The electronic code lock gets the allowed unlock time by decoding and checks the code effectivity. No same code will be observed during the lock effective cycle, and the key for code and decode is sole to the lock.

Description

Technical field: [0001] The invention relates to an electronic password lock system and its control and unlocking method, which can be used for access control of container transportation, field machine rooms (boxes), important warehouses, bank ATMs, bank vaults, etc., and belongs to an electronic lock. Background technique: [0002] The access control of container transportation, field computer rooms (boxes), important warehouses, bank ATM machines, bank vaults, etc. all have three common characteristics. The first characteristic is high security requirements, and the switch locks must be strictly controlled. The second feature is that the lock is not frequently opened and closed. The third characteristic is away from the monitoring center. For the access control management of these occasions, the use of traditional mechanical keys has problems such as low security, difficult key management, and low work efficiency. There is a problem of high network investment in the curr...
