The invention relates to an electronic device for opening and closing control by exchange of random codes carrying identifiers and states. It is constituted by an electronic lock (3), a box (1) ensuring the management of the opening and closing procedure, providing the electrical energy necessary for locking and unlocking and being placed in a receptacle shoe (2 ), thus allowing the connection of the box and the transfer of data to the lock, telephone communication equipment (4) and operating software (5) ensuring the control of access authorizations and the memorization of events. according to the invention is particularly intended for locking and unlocking safes, armored cupboards, doors and airlocks by identifying the site and the operator and by verifying the presence and physical condition of what is inside protected volume.

Description

The present invention relates to an electronic control system

  actuating electromechanical locking and unlocking elements.

  There are currently many models of autonomous electric locks on the market such as: - autonomous code electric lock, the opening of which is conditioned

  by recognizing an access code.

  - autonomous electric lock, the opening of which is conditioned by the

  reading an identification badge with or without contact.

  - autonomous electric lock using a mixture of the two techniques

previous.

  In all the cases mentioned above, the user is a single person who tries to identify himself to gain access, without the control of an authority.

  superior responsible for overseeing the operation.

  Patent application N 2728613 shows an example of a lock which does not require an external source of energy and whose opening is conditioned by the recognition of an access code. In an improved version, the system is associated with a non-volatile memory carrying an identification code of the lock to be protected which can be read by the circuit

  electronic and compared with its preset code.

  Also in application WO 96/03563 the depositor has developed an electronic lock matching the identification codes of the key

  electronic and lock and allowing the door to open.

  Both of the aforementioned locks have a major defect in the event of loss of key since requiring replacement of the elements of the

  device and especially their reprogramming.

  In addition, these systems have the major drawback of not being able to

  authenticate the operator, in particular in the event of theft of the electronic key.

  Only the contribution of a third control element can generate

operator authentication.

  The object of the present invention is to overcome the aforementioned drawbacks by proposing a particularly simple and inexpensive device with a higher level of security than electronic systems equipped with transmitters. The system can be installed in places not connected to the network

  electric and wired telephone.

  It can easily be adapted to other existing locking systems,

electromechanical and mechanical.

  -2- Preservation of the confidentiality of access codes is no longer necessary in the present invention since exchange codes are used

unique and instant.

  These aims are achieved by an electronic device comprising an electronic lock, a box ensuring the management of the opening procedure and supplying the electrical energy necessary for locking and unlocking, telephone communication equipment and operating software ensuring the control of access authorizations and storage

events.

  Other characteristics and advantages of the present invention will emerge

  better by the following description, given as an indication and not limiting, in

look at the accompanying drawings.

  In FIG. 1, the mark 1 represents the electronic box which is placed in the receptacle shoe (mark 2), thus allowing the connection of the box and the transfer of data to the lock (mark 3). The mark 4 symbolizes the means of communication by a phonic connection equipment, that is, for example, a mobile telephone, this between the operator and the

remote monitoring (item 5).

  Figure 2 shows the code calculation method.

  The lock has an identifier. The dialog box also has an identifier. The connection of these two elements is done by

  the introduction of the housing into the shoe.

  A primary code is then developed, according to the block diagram (Figure 2), composed of eight alphanumeric characters, composed of numbers and letters from which are excluded those likely to present an ambiguity, ie 32 possible values for a character. The primary code defined can take 32

  power 8 possible values, each value of which characterizes the lock-

  6f5 box from the connection, in a given state.

  As moreover it is imperative to diversify the values of the primary code as much as possible, in order to protect against replay, it contains an element

  diversifying evolutionary and random.

  The door can therefore only be opened with a

  second code says opening code.

  To obtain this opening code, the operator must first call the remote monitoring center by phonic communication in order to

  give the primary code and authenticate.

  The operator of the remote monitoring center enters the code and queries its database which provides it with the following information: -the number and location of the lock; - 3- - the physical state of the lock (door open or closed, assault alarm); - the state of external elements; - the number of the dialog box;

- the name of the operator.

  Having these, he remains in control of his decision to issue or

not the opening code.

  After checking with the operator and if the situation under control is correct, the remote monitoring operator validates and obtains the opening code. This code, calculated by the software, is a unique code calculated for each intervention and this for the purpose of absolute security.

against replay.

  The operator transmits to the operator by the same voice communication channels, the opening code obtained. This code is entered on the keypad of the dialog box to open the door immediately

  or after a time delay (information carried by the opening code).

  After intervention on site, the operator closes the door, places the dialogue box in the support which provides it with an end of operation code and, via the same communication channels, the operator transmits this code

  of end of operation which will generate discharge to the remote monitoring operator.

  This discharge allows the monitoring agent to ensure that

  the condition of the lock and the successful completion of the operations.

  It is only after this discharge that the housing can be

  operational for another intervention.

  On the other hand, the programmable device comprises means for reading the data, programming carried out by correspondence of random codes, data entries made by a set of keys, a central body which can be taken in hand, provided with '' a connection and display via a display and a lock comprising an identifier and ensuring the electronic management of the opening and closing procedure as well as the acquisition of its physical state and

the state of external elements.
