Abstract

The present invention relates to a method for unlocking central control multi-user electronic coded locks, which relates to the method for unlocking the locks. Each electronic coded lock and a numeric keyboard are connected with a central controller connected with a computer, the computer controls a random generator thereof to generate codes, transfers the codes, and stores the codes in a memory of a central controller, a CPU of the central controller collects the codes dialed in from the numeric keyboard, and compares the codes with the codes stored in the memory, the CPU sends an unlocking signal to the electronic coded lock only when the dialed codes conform to the codes stored in the memory, and then, the CPU unlocks the electronic coded lock. The codes of the present invention can be randomly changed at any time, so the present invention has the advantage of high confidentiality. The present invention is suitable for rooms with a plurality of flowing persons (such as hotels) to use.

Description

The method that center control multi-user electronic cipher lock is opened

The invention belongs to the lock class, the method that specifically a kind of center control multi-user electronic cipher lock is opened.

The disclosed electronic password lock of CN92201527.9 adopts numeric keypad control, and the corresponding fixing password of each coded lock is by pressing numeral on the numeric keypad to realize unlock operation.This electronic password lock is because password is fixed, and the room (as the hotel) that inapplicable mobile inlet is many uses, and safety and confidentiality are relatively poor.

The object of the invention is, the method for a kind of center control multi-user electronic cipher lock unlatching is provided, and can be produced the password of a plurality of electronic password locks by computer random, has improved the safety and the confidentiality of electronic password lock.

To achieve the above object of the invention, the present invention can realize by following measure, each electronic password lock is connected on the center control machine with a numeric keypad respectively jointly, its random generator of the computer control that links to each other with center control machine produces user cipher at random, and show and store this user cipher, simultaneous computer transmits this user cipher and is stored in the memory of center control machine, and the electronic password lock that each described user cipher only allows to link to each other with center control machine uses; User cipher is dialled in from numeric keypad, center control machine CPU gather the user cipher dial in and with its memory in corresponding password compare, CPU control centre controller send start signal to the user's electronic coded lock of correspondence if password conforms to, if password not match then center control machine refusal provides start signal to coded lock.

The present invention adopts the unlatching of all user's electronic coded locks of the unified control of center control machine, computer can produce the password of each electronic password lock at random, the CPU of center control machine gathers the password of dialling in, the unlatching of control lock, password is unfixing, and safety and good confidentiality especially are suitable for the more room (such as the hotel) of movement of population and use, the guest registers the generation password, and guest's after closing password cancels immediately.

Describe the present invention by embodiment below in conjunction with block diagram.

Fig. 1 is method of operating block diagram of the present invention.

Each electronic password lock of the present invention is furnished with a numeric keypad, they link to each other with center control machine jointly, center control machine also is connected with a computer, the circuit structure and the programme-controlled exchange of center control machine are similar, mainly form by CPU and memory etc., the unlatching of electronic password lock control realizes that by the CPU of center control machine numeric keypad can transmit double-audio signal to center control machine.

Computer of the present invention is at first registered the guest, the room number that will use is keyed in computer, its random generator of computer control produces user cipher at random then, and show and store this user cipher, password is sent to center control machine and is stored in the memory of center control machine, this user cipher only is suitable for some (room) electronic password lock that links to each other with center control machine and uses, each electronic password lock can allow to use a plurality of different passwords, center control machine does not monitor the duty of each numeric keypad that is attached thereto off and on, when the user opens numeric keypad and sends user cipher, the CPU of center control machine gathers the code signal that numeric keypad is exported in double-tone frequency mode, compare with the corresponding password that has deposited in its memory, CPU controls its center control machine and send start signal to the electronic password lock of correspondence if password conforms to, electronic password lock is opened automatically, numeric keypad can be implemented closing keyboard after transfering to password automatically, CPU gives this password to computer simultaneously, computer automatically with this password and the information storages such as time that use this password on user's account, call printing in order to operating personnel, if password not match then CPU refusal send start signal to electronic password lock, the employed number of times of the computer tracking accumulative total bad password of CPU control simultaneously, when the bad password accumulative total of transfering to when some numeric keypads are continuous reaches three times, computer is reported to the police automatically and is shown the room number of transfering to bad password, the security personnel can in time take measures, thereby prevented that effectively lawless people from breaking a code, improved the security reliability of electronic password lock.

Claims

1, the method for a kind of center control multi-user electronic cipher lock unlatching, described each electronic password lock is connected on the center control machine with a numeric keypad respectively jointly, the unlatching of described electronic password lock control is realized by the CPU of center control machine, described center control machine is connected with a computer, it is characterized in that described method comprises the following steps:

A, its random generator of described computer control produce user cipher randomly, and show and store this user cipher;

B, the described user cipher of storage are in the memory of described center control machine, and the electronic password lock that each described user cipher only allows to link to each other with center control machine uses;

C, described center control machine CPU gather user cipher that described numeric keypad dials in and with its memory in corresponding password compare;

If d password not match then described CPU control centre controller, refusal provides unlocking signal to electronic password lock;

If the e password conforms to, described CPU control centre controller send start signal to the user's electronic coded lock of correspondence.

2, the method for opening according to the close lock of claim 1 described center control multi-user electronic, when it is characterized in that in the memory of said dial-out password and center control machine corresponding password not match, then described computer tracking is dialed the wrong number by this numeric keypad and is missed the number of times of password, when dialling number of times surpasses three times, then described computer is reported to the police automatically and is shown the pairing room number of this numeric keypad.
