Description

The invention relates to electronic locking and monitoring systems for an alarm mechanism with data carriers and a non-contact reading device for data carriers outside the security area and at least one activatable burglary and / or status reporting system with connected blocking elements and / or sensors and an interposed switching module within the security area.

Money cards, key fobs, badges and other screw-in flat circular disks for customer recognition in service systems represent a major application field for wireless code recognition.

Wireless smart cards are among other things in the pamphlets DE 42 27 551 A1 (Chip card with field strength detector), DE 42 39 806 A1 (Non-contact IC card), DE 42 42 112 A1 (Control for a switched load of an IC card), DE 43 02 387 A1 (Non-contact, portable storage device) and DE 43 37 921 A1 (Contactless chip card with antenna coil and method for their preparation) described.

The power supply and the data transfer takes place via antennas in the reader and in the card. Special measures for data security of a non-volatile memory in the card in the process of reading or writing are also found in these solutions.

In the pamphlets DE 40 03 212 A1 (Device for the identification of general cargo) and DE 43 27 342 A1 (Reusable Transport Containers) are industrial applications for the identification of products themselves or of transport containers. In the reusable transport container for conveyed a mobile data carrier is attached to this. This contains at least one transmitting and receiving device for electromagnetic waves, which are sent for wireless transmission of data to an external station or received by this, and a non-volatile memory connected to the transmitting and receiving device, connected to drive circuits. This is designed for writing and reading data. The disk is housed in a hermetically sealed, approximately cuboid housing, which has only a small thickness. On an outside of the transport container, a bag is attached, which consists of an elastic material, for. As plastic, consists and is accessible from its upper narrow side of an opening. Into this bag the externally existing data medium is placed.

The publication DE 40 03 212 A1 includes a device for the identification of general cargo. A surface contained in a data carrier has partial regions with different permeability. It is possible to detect the magnetic permeability of the subareas via an external read head, which consists of a multiplicity of magnetic sensors arranged in matrix form. Thus, a writable and readable code carrier is arranged in or on the product. On the power supply of these solutions will not be discussed.

Cards that can be read in direct contact by means of a reader have become known through many publications. Such maps with fixed or externally definable data are widely used today.

In the pamphlets DE 39 28 107 A1 (Method for coding and availability of a smart card) and DE 40 12 931 A1 (Method and apparatus for individual electronic identification of ID cards) complete systems including the cards are described. For this purpose, either cards according to a mother card or prepaid ID cards are checked for identity. The cards have a time limit. If such cards are lost before the expiration, a change in the reading system is given only by a great deal of effort. Applications of these cards by unauthorized persons are given over a relatively long period of time.

The publication DE 40 25 229 A1 (Coding system) describes a system, wherein a card is provided for a plurality of card readers. The number of necessary cards should be limited for cardholders. Several identification features are programmable by the user. However, if lost, the reading systems can not be changed without great expense.

Especially with regard to the individually identifiable identification features, there are great uncertainties in the event of loss. The reference to an extension by the comparison of stored personal characteristics increases the effort and thus the costs for the reading systems substantially.

The publication EP 0 543 176 A1 includes a burglar alarm system. This is located in the protected area and can be operated via an operating unit. The latter is a separate device, which has a keyboard, a display device, a communication unit and an input slot for magnetic or smart cards. The entry code is entered via the keyboard or via the magnetic or chip card placed in the slot. The data is transmitted to the burglary alarm system via a galvanically isolated or galvanic transmitted connected coupling between the control unit and burglar alarm system. The control unit is supplied via an energy source without contact via an inductive electromagnetic or optoelectronic coupling or via a galvanic coupling with electrical power. It is an alarm system that can be switched on / off in different states via this operating unit. The control unit works analogously to a conventional key or switch.

Through the publication DE 297 15 426 U1 is a contactless actuated switching unit known. From this, in addition to access cards, passive programming cards, passive erasure cards and active erasure cards are known. The publication DE 24 40 729 C3 includes an alarm system, wherein the user receives an indication when switching whether, for example, all locking elements are closed. This is done via an additional signal. The user can thus decide whether the alarm system should be turned on even in the case of improper condition of a blocking element and this remains in this state.

With the solutions from the pamphlets DE 43 44 314 C2 (Procedure for arming a burglar alarm system by means of a mortise lock) and DE 196 37 623 A1 (Arming device for a burglar alarm system), the switching of an alarm system via mechanical locks, which are actuated by a key. The alarm system is operated via the key and its movement in the lock.

The publication DE 33 41 900 C2 includes a circuit arrangement for locking and unlocking of security systems by remote control. The known circuit arrangement is characterized by a greatly reduced transmission energy.

Through the publication DE 295 21 095 U1 a device for arming / disarming an alarm system is known, wherein the alarm system can only be armed and / or disarmed when the code received from an identification card is valid.

The indicated in claim 1 invention addresses the problem of providing an activatable with transponders electronic locking and monitoring system for closing and opening of activatable burglary and / or state reporting systems.

This problem is solved with the features listed in claim 1.

The electronic locking and monitoring system according to the invention is characterized in particular by the fact that the activation (arming) or disabling (disarming) of burglar and / or state alarm systems, in particular alarm systems takes place in succession in two steps via data carriers. In this case, the proper closure and the activation of the blocking elements and / or the functions of the sensors are checked in the first step. In the second step, after arming the first step, the arming, in particular of an alarm system, takes place as a burglary and / or status alarm system. This prevents that in case of improper and therefore faulty or open state of the locking elements and / or sensors connected to the alarm system, the alarm system is still armed.

The arming and disarming of the alarm system takes place only on the chronological succession twice comparing and checking the data of at least one valid data carrier. This situation increases the security against unauthorized operation of the locking or monitoring system.

With a spatial separation of the switching module and reading device, the operation of burglary and / or state reporting system in the form of an alarm system in particular for unauthorized persons much more difficult, so that the same security is increased. In this case, the reading device is outside and the switching module and the burglar and / or status reporting system within the security area. The data transfer takes place via only one data line. This further increases the safety aspect of the electronic locking and monitoring system.

Advantageous embodiments of the invention are specified in the claims 2 to 6.

The developments of the claims 2 to 4 leads to a non-contact electronic locking and monitoring system according to the invention. This situation increases the security against the use of unauthorized persons. One possibility of manipulation is essentially avoided, so that the highest possible safety standard is ensured. The operation in the form of arming or disarming the burglary and / or state reporting system and the installation of the data of the selected rights is carried out via at least one passive coded authorization card, passive programming card and passive deletion card, which are designed as transponders. This gives a non-contact operation. Power is supplied by the power of an LC oscillator in the reader. The transponders themselves are passive. These are thus always ready for use. Malfunction caused by a not sufficient or insufficient power supply is avoided.

With the different cards, the operator has access to a complex locking and monitoring system. All activities, in particular during commissioning and selection of the authorized persons, are feasible on site and by the operator himself. For this purpose, the data of the required authorization cards are individually stored in the memory of the reading device on site via a passive programming card. This results in the advantage that the operator requires only a certain number of authorization cards. The increase of this number is easy to carry out on the state of the programming mode of the reading device on site. This results in a universal applicability. Time losses in extensions that are associated with a reprogramming eliminated. The operator is able to carry out this programming himself and on site, so that cost-intensive operations by the manufacturer are eliminated.

The reading device is further distinguished by the fact that by means of a passive erase card all data of the memory can be deleted immediately. This fact supports a universal and cost-effective applicability of the locking and monitoring system.

Another significant advantage is that the data of individual access cards in the reading device can be deleted on the spot via an active erase card according to the developments of the claims 5 and 6. Especially in this day and age, which is characterized by an increasing number of cards for a variety of applications, loss of cards is easily possible. This will enable unauthorized persons to operate the burglary and / or status reporting system. When the loss becomes known, the authorization can be blocked on site and as quickly as possible. This also reduces the inhibition threshold of the notification of the loss of an authorization card among the employees, as a change in the authorization is cost-effective. Of course, the operator can also carry out the authorization for changes in the company as quickly as possible, so that it can be easily extended or restricted. Unnecessary economic expenses regarding new reading devices or reprogramming at the manufacturer are avoided. Furthermore, eliminates a time-consuming exchange of all authorization cards.

An embodiment of the invention is illustrated in the drawings and will be described in more detail below.

To show:

1 a basic structure of the electronic locking and monitoring system and

2 a block diagram of the active erase card.

An electronic locking and monitoring system for at least one shutter, a control and / or an alarm mechanism and a method for activating or deactivating burglar and / or status reporting systems with connected blocking elements and / or sensors is summarized in an embodiment described in more detail below.

The electronic locking and monitoring system for at least one shutter, a control and / or an alarm mechanism consists of at least one disk, a reading device 2 for data carrier, a switching module 3 and an activatable burglary and / or status reporting system, in particular an alarm system 4 (Presentation in the 1 ).

The data carriers are as transponders 1 educated.

The reading device 2 for transponders 1 consists essentially of a reader, a memory 10 for the data of the transponder 1 , a control device in the form of a microcomputer 9 and different ads. The reading device 2 is via a serial data line 11 with the remote switching module 3 connected. This consists of two switching elements in the form of two relays 12a . 12b , a microcomputer 13 as a controller.

• – zum Ersten eine Überprüfung des ordnungsgemäßen Verschlusses aller Zugänge, z. B. in Form von Türen und Fenstern, und eventuell weiterer Verschlusssysteme,
• – zum Zweiten die Aktivierung von Sperrelementen und
• – zum Dritten die Überprüfung des Zustandes der Sperrelemente.

Furthermore, the switching module 3 several inputs for monitoring lines 14 on. With the first relay 12a via the alarm system 4

• - First, a review of the proper closure of all accesses, eg. In the form of doors and windows, and possibly other closure systems,
• - Second, the activation of blocking elements and
• - Third, check of a condition of blocking elements.

The second relay 12b used for arming the to the switching module 3 connected alarm system 4 , With an input, the arming readiness of the alarm system 4 detected and with another input the switching mode of the second relay 12b set.

The following is based on the arming and disarming the alarm system 4 the operation of the switching module 3 in connection with the reading device 2 described in more detail.

arming

The alarm system 4 the inventive electronic locking and monitoring system is out of focus, that is, the alarm is not activated and the locking elements are open. First, all accesses, z. B. in the form of doors and windows, and closure systems closed and closed. Now a transponder 1 in the form of an authorization card in front of the reading device 2 and via the reader the data of the transponder 1 detected. Voices the data of the transponder 1 with data in memory 10 the reading device 2 match, gives the reader 2 an acoustic and / or optical signal via one and / or several display devices. At the same time, the electronic locking and monitoring system is blocked. This state and thus the readiness to arm the alarm system 4 will be signaled again. In a certain time window, the transponder must 1 a second time in front of the reading device 2 being held. Now, after another short signal the microcomputer 13 of the switching module 2 instructed via a serial data line, the first relay 12a to switch. The at the switch contacts of the first relay 12a connected alarm system 4 then performs the verification of proper closure of all accesses, such. As in the form of doors and windows, and closure systems, the activation of the locking elements and their review by. If the result is positive, the signal becomes ready for arming to an input of the switching module 3 given.

Then the second relay becomes 12b over the microcomputer 13 controlled and the alarm system 4 armed.

disarming

The alarm system 4 is armed. Will now be a transponder 1 in the form of an authorization card in front of the reading device 2 held, the data of the transponder 1 and the data in memory 10 compared. If the comparison is positive, the current status of the alarm system is signaled 4 , After a certain period of time, the readiness for disarming is again announced by signaling. Now turn within a tent window, the data of the transponder 1 once again read positively, via the serial data line 11 the instruction to the microcomputer 13 of the switching module 3 , the second relay 12b to switch. After a certain period of time, the first relay will be activated 12a switched and the alarm system 4 is out of focus.

Arming in case of failure

The alarm system 4 is out of focus, that means the alarm system 4 is not activated and the locking elements are open. First, all accesses, z. B. in the form of doors and windows, and closure systems closed and closed. Now a transponder 1 in the form of an authorization card in front of the reading device 2 and via the reader the data of the transponder 1 detected. Voices the data of the transponder 1 with data in memory 10 the reading device 2 match, gives the reader 2 an acoustic and / or optical signal via one and / or several display devices. At the same time, the electronic locking and monitoring system is blocked. This state and thus the readiness to arm the alarm system 4 will be signaled again. In a certain time window, the transponder must 1 a second time in front of the reading device 2 being held. Now, after another short signal the microcomputer 13 of the switching module 3 via the serial data line 11 instructed the first relay 12a to switch. The at the switch contacts of the first relay 12a connected alarm system 4 then performs a check on the proper closure of all accesses, eg. B. in the form of doors and windows, and closure systems, the activation of the locking elements and their review by. If the shutter is faulty, the arming readiness signal will remain off. This situation is signaled. The second relay 12b is not activated, the first relay 12a falls off again and unlocks the entrances and locking systems.

In a manipulation of the reading device 2 By drilling, stun gun, short circuit or interruption of any lines is when armed alarm system 4 the state of the relays 12a . 12b not changed.

Next to the transponders 1 In the form of authorization cards, the locking and monitoring system can continue to at least one passive programming card, a passive deletion card as a transponder 1 and an active delete card 15 include.

The reader for contactless recording of transponder data 1 in the form of authorization cards operates inductively and consists of an LC oscillator 5 as a sine wave generator and from a series connection with a demodulator 6 , a selective amplifier 7 , a comparator 8th and a microcomputer 9 with memory 10 , The oscillator frequency is 125 kHz ± 5%.

The power supply of the transponder 1 takes place without contact by means of the power of the LC oscillator 5 of the reader. The coil of the oscillator 5 is connected to the input of the demodulator, so that this both as a transmitting coil to power the respective transponder 1 as well as a receiving coil for the data.

Before first use or after completely erasing the memory of the reading device 2 is the memory 10 the reading device 2 empty. By holding, that means in the reception and transmission range of the LC oscillator 5 , at least one passive programming card goes the microcomputer 9 the reading device 2 in the programming mode via. Now the required and desired coded transponder 1 as authorization cards one by one and in succession in front of the reading device 2 brought. In the process, the data of these transponders 1 in the store 10 the reading device 2 stored. The microcomputer changes with the renewed provision of the passive programming card 9 the reading device 2 from programming mode to operating state.

Other coded transponders 1 as authorization cards are always in the store 10 the reading device 2 readable with the help of the passive programming card, so that without great expenses and thus, simply the circle of the entitled ones can be constantly extended by the operator himself.

The entire stored data of the transponder 1 as authorization cards are deleted immediately and completely by the passive deletion card. Thus, the state is reached before the first commissioning and the reading device 2 is available for further use.

Another advantage arises with the use of the active erase card 15 whose principal realization in the 2 is shown. The active delete card 15 consists of a housing in which a keyboard 16 and a visual display 17 are integrated, a component carrier and a closable from the outside space for receiving at least one chemical power source 20 in the form of at least one battery. Using two keys on the keyboard 16 becomes the operating state of the active erase card 15 selected.

By turning on and placing this active erase card 15 in the transmitting and receiving area of the reading device 2 a menu is displayed via the visual display 17 the active delete card 15 , The data between the reader 2 and the active delete card 15 be via the LC oscillator 5 the reading device 2 and a transmitter swing 19 the active delete card 15 replaced. A microcomputer 18 with built-in memory in the active erase card 15 controls the electrical components and thus all necessary processes. It is possible individual codes of coded transponders 1 as authorization cards via the keyboard 16 then enter the contents of the memory 10 the reading device 2 to be deleted.

• – Zahlen 0 bis 9 für die Eingabe eines Codes,
• – eine Taste „Ein-ON”, die potentialfrei ist, so dass der Stromverbrauch im Ruhezustand im nA-Bereich liegt,
• – eine Taste zur Korrektur der Eingabe des Codes und
• – eine Taste für die jeweilige Bestätigung und dem Start der Löschung des Codes im Speicher 10 der Leseeinrichtung 2
• – Tasten zum Blättern in dem Speicher 10, so dass mehrere zu löschende Kartennummern in die aktive Löschkarte 15 eingegeben und gespeichert werden können.

The microcomputer 18 with built-in memory is with the keyboard 16 , the optical display 17 and the transmitter oscillation circuit 19 interconnected ( 2 ). The keyboard has several buttons:

• - numbers 0 to 9 for entering a code,
• - A "ON-ON" button, which is floating, so that the power consumption in the idle state is in the nA range,
• - a key to correct the entry of the code and
• - A key for the respective confirmation and the start of the deletion of the code in the memory 10 the reading device 2
• - keys for scrolling in the memory 10 , leaving multiple card numbers to be deleted in the active deletion card 15 can be entered and saved.

The latter fact is particularly advantageous when several electronic locking and monitoring systems are in use and a number of numbers are to be deleted in all systems.

The power is supplied by means of two lithium cells, so that a long service life is given.

In the sharp state of the alarm system 4 is the reading device 2 through the passive programming card and active programming card 15 can not be put into programming mode, so that no additional data can be read in. The same applies of course to the deletion card.
