Abstract

The system has a key (1) with a chip (9) recording an identification number of a lock (2) when key exerts constant pressure on a knob (10) of a lock. A microcontroller gives an order to a solenoid (12) for blocking a mechanical part of the lock. The lock stores in its memory (7) the identification number of the key if a detector (6) detects that the locking of electro mechanical assembly is correct. The lock does not store the identification number of the key and erase its identification number in the key, if the detector detects that the locking of the assembly is not correct.

Description

Programmable electronic closing system.

The invention concerns a closing system programmable electronic, especially for doors with uses of unassigned users.

This type of system has the advantage over to other more conventional systems, in which each lock I had assigned a key, that each user can use any lock that is available without previously one has been associated.

This is possible due to the already known fact of that lock and key can exchange information with each other, thus achieving a less restrictive operation, so that the key and the lock assign their codes to each other without need for an external element and without associations be determined prior to the use of the lock for that key.

The system therefore consists of a lock and a read-write key, which are based on the RFID technology, establishing two-way communication Between both elements.

The locks that make up this system do not have therefore need to be communicated with each other, or a unit central, while any key can be used in Any lock that is not already occupied.

This key after being used in a lock cannot be used in any other lock of the same installation.

This type of systems is described in the EP 0911466, but its electromechanical structure and its program of operation presents a series of inconveniences and problems that Then they will be discussed.

In EP 0911466 the lock has a knob. The key presses the knob which moves longitudinally. The key can be removed to perform the lock of the lock, that is, so that the knob turns the key is no longer in contact with the lock.

In the system object of the invention the key is in continuous contact with the knob and there is no interruption of key-lock communication, which enables a different operating schedule more than according to the needs of the user and consequent advantages.

The programmable electronic locking system object of the invention is those consisting of locks and keys that incorporate programmed electronic elements that enable two-way communication between lock and key without contact each other, in which:

a) each key consists of a number of identification and of an antenna and a chip;

b) each lock consists of a number of identification and is characterized because it consists of the following elements:

b_ {1})

an electromechanical assembly formed by a mechanical part consisting of a movable knob and  solidarity with a tongue and an electrical part consisting of a solenoid that locks / unlocks the mechanical part,

b_ {2})

a sensor that checks that the solenoid is performing the lock / unlock correctly,

b_ {3})

a microcontroller that communicates with an antenna built into the knob, with a memory, with the detector and with the solenoid, so that the following occur successively done in its closing function:

c) the key approaches the lock and presses continuously to the knob that travels and while traveling it records the identification number of the lock on the chip of the key,

d) the microcontroller orders the solenoid that lock the mechanical part of the lock,

e) if the detector verifies that the blocking of the electromechanical assembly is correct, the lock stores in your memory the key identification number, and if the detector check that the lock is not correct will not save in memory said key identification number and will be deleted from the chip of the key the identification number of the lock.

In this system in its opening function, the lock will verify that the key that has approached and presses the knob is correct, and in that case it will activate the solenoid to Unlock the knob. If the detector verifies that the mechanics have functioned correctly, the lock will erase the memory of the key the stored lock number and also delete from the lock memory the key number. If not the data in the key memory lock can be deleted or the lock cannot verify that it has been done correctly, the key data will be deleted from the lock since the mechanics worked correctly, so that lock can Be used by other keys. In turn that key can be recovered using that same lock.

In addition, the lock may incorporate into your electronic of a clock chip, so that the lock can check the rights or prohibitions of the key depending on the expiration date of the key.

The advantages of the system object of the invention are many, being able to highlight the following:

In the system of the invention, the information engraved on the key corresponds to the lock number that has been used, instead of recording the state of the lock, which is what indicated in the aforementioned patent, which facilitates the consultation by the user of which is the lock that has occupied, in case of forgetfulness, by means of an Infoterminal or terminal of information. In addition, this ensures at all times that in case of an error in the creation of the key and that your code is has duplicated in two different keys, only the key that has been used in the lock and therefore has the lock number in your memory, you can release it.

In the system of the invention, the recording in the key number lock that has used it, is only done after it is verified that the mechanics have worked correctly and the lock is locked and closed, of so that in the event of a closing or blocking failure, said lock does not it would keep in its memory the number of the key with what could be used by a different key. In EP 0911466 the lock is assigned with the key data before or during the lock so in the case of incorrect lock the lock It could remain busy and be unusable by another key.

In the system of the invention the key can be used in locks of different groups in the same installation which makes it easier for the user to access locks with different applications (for example a lock in the locker room and another in the cafeteria area to leave the sports equipment) without Need to have two keys.

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 1 is a block diagram of a practical realization of the system object of the invention.

The system consists of a lock (2) that carries an identification number and a key (1) that carries a identification number.

The lock (2) is formed by an antenna (4) which serves to communicate with the key (1), an electronics of control (5) (microcontroller) that controls the program operation of the lock (2), an electromechanical assembly (10) (3) (12) (11) consisting of a mechanical part (10) (3) (11), an electrical part formed by a solenoid (12).

Between the knob (10) and the tongue (11) are establishes a block (3) of kinematic transmission.

It also consists of a detector (6) and a memory (7) where the used key number and the data of the lock. The key (1) in turn is formed by an antenna (8), and a chip (9) where the lock number (2) will be stored and where the data referring to the key (1) are stored.

The control electronics (5) of the lock (2) may or may not carry a clock chip to allow the use of the lock according to the permits or prohibitions corresponding to the data on the expiration date of the key (1).

The process of operating the system in its Closing function is as follows: the key (1) approaches the lock (2) and continuously press the knob (10) where find the antenna (4).

During the pressure of the knob (10) and integral with he by the kinematic block (3), the tongue (11) leaves the housing (C).

Once the knob (10) is pressed, the lock (2) starts reading the key (1) and checking of your data.

If the key (1) does not have the number of any another lock (2) stored, the lock (2) will record on the key (1) your identification number, thus leaving it unusable for another lock (2) of the same group.

At that time the microcontroller (5) of the lock (2) will order the solenoid (12) to lock the lock (2), thus leaving it locked in the closed position, this is get through a solenoid (12) that leaves the movement of the knob (10) towards the outside and therefore of the tab (11) towards the inside of the housing (c).

The lock (2) has a detector (6) that check that solenoid (12) is blocking correctly.

If the mechanics work correctly, the lock (2) will store in its memory (7) the number of key identification (1), to allow when so the user is required to release the lock (2).

In case the mechanics do not act correctly, the lock (2) will not store in its memory (7) the key identification number (1) and will erase the key (1) your lock identification number (2).

In the operation of the system in its function opening can be the inverse of the one described in the closing function or the next:

The lock (2) will check that the key (1) that has approached and pressed the knob (10), it is correct, and in such case will activate the solenoid (12) to unlock the knob (10).

If the detector (6) checks that the mechanics have functioned correctly, the lock (2) will erase from memory (7) of the key (1) the lock identification number (2) stored and will also erase the memory (7) of the lock (2) the key identification number (1).

In case data cannot be deleted from the lock (2) of the memory (7) of the key (1) or the lock (2) cannot verify that it has been done correctly, the data of the key (1) will be deleted from the lock (2) since the mechanics has worked correctly, so that lock (2) can be used by other keys (1).

In turn that key (1) can be recovered using that same lock (2).
