Abstract

This lock can be equipped with modules for additional assignments. The card (1) comprises an additional area (50) for coding additional data which does not affect the validity of the card (1). These data are transferred by the reader (4) to a register (51) which feeds an additional calculation means (52), which examines this register in relation to the respective modules (53, 54, 55, 59, 60, 61) which enable additional attributions. The logic output (56) of (52) is normally activated and, if the result of the examination of the additional data is negative, it goes to a false value, by inhibiting the electromechanical means (18) of opening the lock.

Description

The object of the invention is a programmable electronic lock which has been

developed on the basis of the patent

  Spanish No. 532 333 by the same holder.

  This development was carried out on the basis of a modularity criterion which, taking as minimum basic configuration, that of said patent 532 333, is designed to selectively comprise different modules intended to give additional attributes to the user without affect the general validity of the

  card that relates to the basic configuration.

  Although the areas of application of this

  lock can be very varied, we refer particularly

  in the following in the case of a hotel, which is the most typical and the most expressive of versatility and

  high performance of this lock.

  Already in the aforementioned patent 532 333, it is described

  already has an action- programmable electronic lock

  born by a support such as a card or card, coded with

  card and shift codes that are automatic-

  updated the first time a new card is

  customer's calf entering the room is inserted there, provided that the difference between the last key code developed and the new card code, minus the last lock code previously recorded by the lock

  gives one or two jump units as a result.

  Also in this patent 532 333, it is envisaged

  managed the possibility of carrying out instructions. For this, the cards carried information of the type (19),

  to which they belong, and the lock possessed different

  different registers (22a, 22b, ...) for storing co-

  of different, relating to each of the types. These codes acted independently of each other. One type was reserved for customers, another for the master card

  general, another to master cards of floors, etc.

  Code changes in a type do not affect

  other; thus, a new client cancels the previous client

  laughing but does not affect the mattresses.

  The services indicated are sufficient for

  bedroom door locks but in the

  such, there are in addition many other services (the room safe and refrigerator, the swimming pool, the sauna, the parking lot, ...) and access (main door, hardware stores ,. ..) who are also authorized using electronic locks,

  which must respond to different behaviors

  tincts: some of these locks are autonomous and are prepared to open only a client's room and certain master services; others must open some or all of the guest rooms of

  the hotel; others are wired to the receiving computer

  tion which edits the cards so that they are inform-

  customer ascents and descents.

  Other known locks different from those

  of the patent 532 333 use the system consisting in handling

  always pump a single code which, in combination

  with a clock, is validated if you are in

predetermined time mites.

  The new lock principle will simplify the management of the hotel system in question, which requires locks with different capacities and different functions; by creating a system

  modular locks and codes contained in the

  tes, which covers all possible variants

  based on a compatible basic structure

  which can optionally be carried out with one, more

  sieurs or all possible modules intended to enable

  ter other attributions to the user, by the creation

  tion of separate lock configurations suitable for

  each function and each need.

  For this, the new lock stands out and

  is characterized by the fact that said card or said sup-

  coded port includes additional area for coding

  additional data which do not affect the validation

  té de la carte, if not the attributions of the user

  and which are transferred through the player to a regis-

  tre of additional data which feeds an additional calculation means equipped with logic circuits which make it capable of examining said register of additional data in relation to the modular elements

  which authorize the said additional powers-

  are designed to process said additional data.

  tional, and can be optionally incorporated according to the desired final configuration of the lock, according to the needs of the station, said calculation means having a logic output which is normally activated and which, if the examination of said additional data is

  negative, goes to false value, inhibiting the action-

  said electromechanical means through a logic "AND" gate, which is supplied to its other

  entry through said "OR" door; by the fact that between the-

  so-called multiplexers, the previous unit registers

  for each type of card have been replaced by other

  very registers which authorize multiple registers

  tincts for each of the different types of pre-

  seen; and by the fact that there is a special register

  for the value of the maximum jump between cards, which feeds

  another input of said comparator, the output of this

  comparator activating when, if the register is inferior

  laughing at the lock code register, there is a jump in consecutive cards less than the content of said register which can reach up to a hundred or more than a hundred

jump units.

  According to the invention, said additional data-

  the do not necessarily have to appear in all the cards and in each of the cards except that, according to the function provided for the card-lock assembly and according to the complexity of the lock system installed,

  there will be cards with all of the said data

  additional or only some or none of

those data.

  In general, the functionality of the invention

  tion consists in that all the locks examine the card code and compare it with that which they have in memory to determine if it is valid, by carrying out the change of this code if necessary; in

  adjusting for this to the process and to the elements already defined

  written in patent 532 333 and to which reference will be made

  further. In addition, data is processed.

  additional openings of the card which, when they have them, are examined by the locks which are prepared

  to do it, either for some or for the totali-

  you. These are not important data for the validation

  card, since the card is valid if

  it has the latest edited code for a room.

  However, this is useful data for filtering access.

  access to certain common areas or to cause ac-

  special operations of the lock, etc., according to a di-

  a variety of possibilities, details of which will be given

  after. However, it is advisable to give an example beforehand which will explain this described functionality: if a lock contains a clock, it will examine the date of lapsing of the cards. A valid card, but whose expiration date has already passed will not be able to open

  this lock, while it could open a lock-

  re devoid of clock. If we go up to the door of the

  bedroom a lock with clock while on the chest

  fre-fort, we mount a lock without clock, both can be opened by the same customer card. The safe does not require a clock because, when the

  expiration date has passed, the door lock re-

  throw the card away and the customer will not be able to access or

bedroom or safe.

  Among the multiple possibilities offered by this new principle, we have expressly selected the

  additional data which is described and defined below.

  - Authorizations: they are varied and are

  previously paid for various services, such as the swimming pool, car park, sauna or safe. The pool lock is programmed to open only to cards that have authorization

  corresponding activated. When editing the map, each

  that authorization is activated or deactivated depending

  of the customer's category or wishes.

  - Lapse date: it defines the date and time limit for the time granted to the client. Passed this

  time, the card is rejected in the locks which

  try a clock but it continues to be valid in

  locks that do not have them until

come a new card.

  - Start date: it defines the date and

  time the time from which a card is accepted.

  It is useful in cases of prior editing of

  your for groups, in which we want to avoid the risk

  that one of them is used before the group

  does not arrive, and an effective verification is carried out

  Fri It applies in the same way as the previous case.

  tooth: it will not be rejected before the start date until

  by the locks which contain a clock.

  - Time laps: this defines a time per

  mid several times possible. The lock that contains a clock will only open on this card during the hours that the lock has as allocated for this

schedule.

  - Authorization of the Office function: this function has the effect that the lock which was previously programmed for that can be opened and remain open for an indefinite time by the valid cards which, in addition, have this authorized function. The same

  cards can intervene to leave the lock closed.

  So, in the case of a meeting room, you can edit the normal cards (without Office function)

  for assistants, they can enter but the door

  you close. For the person responsible for the meeting, you can edit a card with the authorized Office function, which allows him to leave the door "busy" for

certain periods.

  - Ability to overcome privacy: the locks

  res usually have an inner button called button

  of privacy which prohibits the opening of certain cards.

  Those with this activated ability can open

  when the privacy button is pushed.

  - Identity of the user: it is a number which is correlated with the user in the archives of the computer which publishes the cards. When the lock has the appropriate elements (clock and memory),

  it makes a recording of the openings in use

  using this number as the user's identity.

  - Keypad code: some locks have-

  tooth a keyboard and require the user that in addition to his valid card, he dials a secret code. This code is different for each user, so that, in the event of the card being lost or stolen, the security of the system is protected by this additional data. To avoid increasing

  lock memory, keypad code is saved

very on the map.

  As regards the new calculation means supplied by the additional data register, optional modular clock elements are provided,

  of lap memory, cancellation of privacy, function

  "Office", or indefinite maintenance of the state of service

  open rure, from open recording memory

  res, and secret personal code keypad.

  In this new construction according to the invention

  tion, validation of cards from the same system is su-

  throws addi- tional data to an independent card code

  which allows for composite locks

  of a basic central block which is the one described in

  the aforementioned patent 532 333, and which confers on them the confi-

  minimum guration, to which one can selectively in-

  body of the aforementioned modular elements, to obtain configurations of greater or lesser capacity,

  which adapt to the needs of each position in the system

  me. If what is added is a time module, the service

  rure will examine the expiry and start dates of the cards. If the lock also has

  scheduled times, it will check, in the case of

  if you have a timetable, if the card is within the limits

  one of the permitted hours; if, in addition, it

  you have more memory than is needed to

  server card codes, it will record

  opening times, with the date and time indicated by its clock and the identity provided by the card; if it has a privacy button and if this button is pressed, it will require that the card be prepared for

  overcome privacy; if we add a keyboard, the

  rure will examine the keyboard code stored on the car-

  te to compare it to the composed code; etc.

  Ultimately, in addition to facilitating management

  tion of complex systems of locks, this new construction will bring the possibility of reducing the cost of the system to minimal levels, by making it possible to use the lock having the most configuration

  economical for each station in the system.

  Another facet that the present invention improves

  liore with respect to patent 532,333 is that which

  identifies recognizing as new and validating recently edited code that differs by one or two units

  of the code stored in the lock code registration

  re. On the contrary, provision is made for the existence of locks which do not read the cards of many successive customers of a room, owing to the fact that these customers do not use certain determined attributes such as, for example,

  the safe or the pool. Consistent development

  You therefore have to recognize that a code is valid and new if the difference is less than a predetermined number which is stored in the special register and which is part of the initial programming of the lock. In this way, the door locks of the rooms have this number equal to 10 to compensate for the improbable case where one would publish 10 cards of successive customers who do not

  are never used; but, for the pool and the cof-

  fre-fort, this number can be equal to 100.

  In addition to the cross-instruction that inhabits

  lite the modular clock element, in combination with the code of the card, the new lock construction allows other possibility of cross instructions which, ultimately, allow that the same lock can be opened by cards which all belong to any one of all possible types

  (customer type cards, master type cards of

  ge, etc.), and with this particularity that changes them-

  code elements in each of these cards do not affect

others.

  For example, in a hotel, there are locks that must allow passage to more than one customer, as would be the case for a lock mounted in the entrance of a corridor that leads to several rooms of customers;

  others must give passage to more than one master card

  braid of the same level, as can be the case for store rooms which can be opened by

  master cards of all floors; and others, including

  me that of the main entrance of the hotel, must give

  Switch to practically all cards valid at the time, whether they are customer cards or master cards. However, in the case of the patent 532 333, among the multiplexers connected to the register of

  type of cards, the lock had a set of regis-

  very each of which memorizes the code of a type of card. Se-

  lon the invention, instead, there is a set of indefinite number registers which store codes of

  cards of the first type, followed by another set of re-

  indefinite number of registers which memorize cards of the second type, and so on until all the possible types of cards are completed; then when we read

  a card of a specific type, there may be a cor-

  correspondence with certain registers which belong to its type. In the method known by the patent 532 333, the lock checks whether the card code is identical to the first memorized or whether their difference is less than

  some value. If so, it acts accordingly.

  quence and cease exploration. If it's not the case,

  it repeats the process with the following register of the same

  me type. The process continues until it finds a valid registry or until it finishes

  the group of registers of the same type.

  Another service provided by this in-

  vention is provided for cases in which it

  just that a certain customer can open the doors of different rooms with his card. This is the case, for example, for a family group if it is rented three rooms and if the parents wish to be able to open the three doors. One solution would be to give them

  three cards. Another is to edit a single card.

  te which contains, instead of a single card code, three

  card codes which correspond to those of the three rooms

  bres. The shift code, type and additional data

  the same as in a normal map and

  are not repeated. In this way, the lock, in line

  sant the card, behaves with the first card code as if it were unique. If it is not valid, it

  makes the attempt with the second card code, and so-

  if on until it encounters a valid code

  or until you finish the codes saved on the card.

  If it finds a valid code, it continues with the exa-

conduct additional data.

  Other features and advantages of the

  vention will be better understood on reading the description

  tion which will follow from an exemplary embodiment and with reference to the appended drawing in which:

  FIG. 1 represents a block diagram

  responding to an electronic combination lock pro-

  grammable formed according to the invention, and which shows the

  most general and total configuration equipped with different

  modular elements 53, 54, 55, 59, 60, 61 which complete the minimum basic configuration specified in

  Patent 532,333 for the processing of all data

  additional births registered in the new zone

50 of card 1.

  Figure 1 shows by a block diagram the

  most general configuration of the lock according to the

  vention, which is made with a modular design

  whose minimum basic configuration corresponds to this

  the patent 532 333 and can be extended by the modules

  optional 53, 54, 55, 59, 60, 61 which operate selectively

  tively with a new area 50 for data coding

  additional newly incorporated in the car-

  te 1. The card 1 therefore includes coding zones 2,

  3, 19, 50 for respective cards, shift codes,

  ge, card type and additional data.

  In accordance with what has been established in the patent

  vet 532 333, the minimum basic lock configuration

  re re works in the following way: when

  insert card 1 in reader 4, the codes of

  te and offset are temporarily stored in registers 5, 6 and are transmitted to a calculation means 7 which likewise receives a system code from a register 9 of the lock, said calculation means 7 uses the code

  system and register shift code 6 as elec-

  Elements for transforming the card code into a key code, which is stored in a register 16 which feeds a

  comparator 17, which also receives a memo lock code

  rise in a register 11 of the lock; this comparator 17, in response to a correspondence between the key code

* from register 16 and the lock code from register 11, pro-

  outputs a signal at its output 13 which, through a door

  "OR" 14, activates electromechanical means 18 from where

  lock lock. When the key code is identified

  that at the lock code increased by one, the other comes out

  tie 12 of comparator 17 is activated and, through the "OR" door 14, it provides a signal which actuates an electromechanical means 18 for opening the lock. At the output 13 of the comparator 17, the signal actuates a control door 10 which updates the lock code of the

  register 11 according to the value of the key code

  kept in register 16. On the other hand, the code of

  card type is temporarily stored in a register

  tre 20, the content of which activates, via multiplexers 21 or 23, one or the other (depending on the specific type of card) from different registers (designated

  par 22a, 22b, 22c and 22d, in patent 532,333), the-

  which register, once activated, at the exit of the multi-

  plexer 23, actuates the control door 25 and transfers

  re the content in register 11 of the lock code; at the same time the output 12 of the comparator 17 acts on the control gate 24 which, through the multiplexer 21, updates the content of the register in question (22a to 22d,

  which corresponds to the type of card.

  In addition, zone 50 of card 1 is now

  read and its content stored in the data register

  additional born 51 from which it passes to calculation means 52 which is equipped with logic circuits capable of operating selectively with a plurality of modular elements

  clock 53, lap memory 54, trip cancellation

  value 55, of "Office" function 59, of storage memory

  very many openings 60 and secret code keypad 61, the functions of which have already been described in detail

  upper; the optional incorporation of all, some

  all or none of these modular elements produces respective configurations of locks for different benefits, depending on the requirements of the system station

  who is busy. When none of the said modular elements

  res 53 to 55, 59 to 61 is not present in a lock, we have the minimum basic configuration of lock expressed

  with additional data possibly incorporated

  rees in zone 50 of card 1; the output signal

  56 then has a true value and the additional data-

  are ignored by this concrete lock, so

  that they are appreciated by other system locks

  me. When a lock comprises one or all of said modules 53 to 55, 59 to 61, the output 56 emits a corresponding signal which feeds the "AND" door 57 which, at its other input, is connected to the door output "OR"

  14, so that the output signal appears at output 58

  electromechanical means tivator 18; it is now

  nant this output 58 which supplies the "AND" gate 31 which supplies the timer 32; and the logic output 56 is normally activated and goes to a false value if the examination of some of the additional data gives a negative result. This signal 56, when it is at a

  false value, inhibits actuation of electro-

  mechanical 18 through logic "AND" gate 57.

  On the other hand, now the multiplexers 21 to 23 operate in relation to registers 40a, 40b, 40c, ...; 41a, 41b, 41c, ...; ...) which are different

  for each type of card, replacing one

  this happened to me previously.

  It should also be noted the novelty which resides in the incorporation of the special register 70 which makes it possible to preset a value of the maximum jump between cards which can be recognized consecutively, with a capacity for jumps of up to 100 or more 100 cards, instead of one or two, as was the case previously; this way it is possible

  establish separate card jumps for locks

  res of the bedrooms, the safe or the swimming pool, as indicated above, and for this, the output 12 is activated when the difference A-B is less than the

contents of register 70.

  To return to the "Office" function, it has already been mentioned that it consists in being able to leave a lock open for an indefinite period of time until

  what we want to close again. So that this function

  tion is really flexible, it is necessary that all

  your cards 1 cannot do it and for this

  there, we have provided additional data, as we have

  I saw it. However, in turn, the owner of a card 1 having an "Office" function does not always wish to leave the lock open Often, he wishes to open it

  and it closes immediately.

  It is interesting to differentiate the two operations

  rations (normal opening and Office function) without aue

  this does not require any accessory elements in the lock

  re, for example a button. For this, if card 1 is inserted only once, the opening is normal. If you insert it twice in a short period, which

  maybe two or three seconds, the first or

  see the lock and the second has the effect that it stays

  permanently open (Office function). A sign

  proper use makes it easier to use, for example a

  green light flashing for three seconds to indicate

keep the lock open.

  To close it, simply introduce new

  calf card 1 twice in a row. The first indicates

  again by the flashing green light that the lock

  re is actually open. The second closes the lock.

re which returns to its normal state.

  As with the other addi-

  these operations are only possible if the lock is programmed to accept the Office function

  and only if card 1 has this function activated. Being given

  born that this does not require accessory elements, does not

  which lock can be programmed as a function lock

  tion Office (or visiting) without it being necessary

  to increase the number of models of locks.

  Of course, various modifications and varian-

  your can be brought by the skilled person to the dispo-

  sitive which has just been described by way of nonlimited example

  without departing from the scope of the invention.
