Description

, / Control device

The invention relates to a control device with at least one stationary control point and one Central data collector assigned to the control points for acknowledging the individual control points / whereby an identifier is assigned to each control point.

As is well known, there are control devices of the aforementioned Art is used on a large scale to largely secure buildings or building sections against break-ins or unauthorized entry - especially outside normal working hours.

While electronic alarm systems that work automatically are mostly used in residential buildings (i.e. small, manageable objects), control by security personnel is common for larger objects such as a factory, a refinery, a bank, etc. There are several systems and methods known, which are under the two terms "guard control ¹¹ and" guard

At the guard control, the echon has been coming for a long time known time clock for use. At each of the arranged at several points of the object to be secured The control point is located in a key box a key whose key bit is mechanically coded and identifies the respective control point. Of the SohlUssel is inserted into the time clock by the guard, which then uses a printing mechanism to show the time / date and the date on a control strip Number of the control body - i.e. the number of the key

The essential feature here is that the guard controls the individual control points, as in the keyword "guard control" is expressed. However, this monitoring has considerable disadvantages afflicted.

More and more companies and also insurance companies are demanding a complete, secure and quickly evaluable over-

p monitoring protocol. But now the control strike

which is the case with large objects to be monitored with many, Checkpoints to be approached at intervals, can be several meters long, poorly evaluate and read. this

leads to the fact that the control strips of the time clock are often stored unread. Only when actually a claim or an insured event has occurred, the control strip is used and checked.

Namely, there is no particular difficulty in copying a cold key / a control key, for example in order to prepare an external control point bypass and acknowledge with the replacement key

to pretend. The low level of security against manipulation can therefore result in insufficient protection due to incomplete protection Conduct patrols.

Finally, the mechanical coding possible Celts in key beards in number to be limited, and in a conventional system 999 comparable Γ different keys are present - that checkpoints - with the appropriate numbering possible. This may be sufficient for individual systems, but in the case of several systems that are spatially separated from one another with the same system, it can happen that a key with a certain number is available more than once. In such a case, for example, a control point of another property in southern Germany could be acknowledged with a control key from northern Germany.

In the monitoring system known under the term guard protection, a radio device with a transmitting and receiving part is used instead of the time clock. In contrast to the guard control, constant contact between the guard and the control center is possible, which enables better protection of the guard and faster detection of a break-in.

To acknowledge the individual control points, these are designed so that the radio device enters the control point can be "plugged in". A radio signal is then sent to the control center, which contains the number of the control but does not include the time. This is recorded by the central office upon receipt, which then takes care of the receipt confirmed by sending an acknowledgment signal, which is an acoustic or optical sig- ■ . nal caused. The guard can now remove the radio from the control point and continue his route.

Although the use of a portable radio device reduces some of the disadvantages described at the beginning, the security guard is also limited in its possible uses and has disadvantages. For larger objects, such as at an oil refinery, it may r- often happen that a control point in the "dead spot" is located, so that from this point of control no radio contact with the control panel is possible. Such radio shadows occur, for example, through larger metal containers (eg cooling tower) or the like.

Furthermore, the radio devices cannot be used to control rooms that have been specially secured with Metdll, e.g. a vault in a bank, because the radio signals cannot penetrate the walls.

Overall, it remains to be stated that the known monitoring systems are not free from disadvantages, see above that optimal property and personal protection is not possible is. This is where the invention, which is based on the object of a control device, intervenes create, which a much better protection and a much better one secured against manipulation Allows control using simple means.

To solve this problem, a control device according to the preamble of claim 1 provides that each control point is formed by a contactlessly interrogable data carrier, the data being stored or arranged along an area and spatially separated from one another, and that the data carrier has a data reading head for serial reading of the data when the read head or the data collector moves via a data carrier and an electronic memory connected to the read head.

By inserting an electronic memory as well by the contactless queryable data carrier whose

- 1 1 -

Data can be encoded and stored in digital technology in the form of individual bits, it is possible with the invention to encode and store a practically unlimited number of different numbers. This ensures / that even within a large local area with several objects to be monitored, each number of a control point actually only occurs once. This significantly increases the security against manipulation.

The acknowledgment or confirmation of a control point is extremely simple with the invention, because it is sufficient to "swipe" the data collector once from top to bottom over the data carrier - control point - by hand. During this process, the data from the control point are dynamically transferred to the memory by means of a serial read. In this way, all the data of a patrol can be saved. The data can then later be logged or printed out and displayed in a control center using a personal computer or the like.

When a control point is acknowledged, there is no cumbersome insertion (either a key in a time clock or a radio device in the control point itself). Hit the omission of the previously required mechanics

- 1 2 -

With the invention, the devices work extremely insusceptible to interference, quite apart from the very simple operation already mentioned.

Leave both the data carrier and the data collector each in a handy plastic housing. The data carrier can be made extremely flat because it only contains a code strip behind its reading area. On the code strip the data of the respective data carrier or the respective control point can be arranged in bit form. The data carrier can be attached to a desired control location, for example, by gluing or screwing. It is also easy to locate the control points over time change.

In order to keep the dimensions of the data collector handy, a rechargeable, relatively small battery is used as the power supply. According to an advantageous further development of the invention it is now provided that the operating voltage source does not remain switched on continuously, but only immediately before the serial reading of the data of a control point for a short time during the reading process is switched on. This can significantly increase the service life of the battery.

- 13 -

The aforementioned switching on of the operating voltage source is carried out by a contact-free activatable sensor, which, so to speak, forms a second reading head for the data collector. This sensor reacts to a magnet, which is located in the data collector above the reading surface behind an inclined surface. If so the data collector for acknowledging a control point by hand from top to bottom on the surface of the Data carrier is moved, the operating voltage squel Ie is first switched on, and then the data is queried and saved.

There is another significant advantage of the invention in that a radio device with a transmitting and receiving part can be connected to the data collector in order to send the stored data to a control center, from where receipt can be acknowledged.

Here, the data of the individual control points in the memory are queried, transmitted and "stored" again in the memory after sending, namely with the "note" that the data of the relevant control point is sent out and from the control center have been received.

-14-

According to a further feature of the invention, the data collector includes "intelligence" in the form of a microprocessor. As a result, unknown options are created for monitoring pages in the sense of increased security.

With the help of the microprocessor - if necessary using a random generator - the Determine certain routes on different days * So it can happen in a certain order can be specified in which the individual control points must be queried. On a display of the After a first control point has been acknowledged, the data collector is shown to the guard which control point he must go to next. Besides the date the time and the number of the respective checkpoint is then also stored in the memory, the chosen route.

The risk of possible manipulation can also be effectively countered in the invention, and the Security can be increased by the fact that the data collector includes a clock chip as a time base, and that the "Regulation" is given to certain control bodies to be acknowledged within a certain time window - i.e. within a certain period of time - Xm memory

- 15 -

of the microprocessor, all checkpoints are closed with a time at the beginning of the inspection which they have to be reached. If the checkpoint in question is not in a particular When the time window is reached, a code call can be sent to the control center by means of the transmitter. Let through it record irregularities immediately.

The use of a microprocessor within the data

significant advantage. In the introduction to the description is |

has already been mentioned above that in the case of the

knew guard protection using a radio the disadvantage can be that the guard is with himself nem radio is in a radio shadow and thus cannot establish a connection to the control center. In the It is now with the help of the control system according to the invention

Central cannot receive the "radio message", this | Repeat the radio message automatically at certain time intervals. The automatic sending of the data of the Checkpoints that have been started in the meantime -will be repeated as long as the acknowledgment from the control center is over the receipt of this data comes. These corresponding

Data are then stored again in the memory with the receiving

- 1 6-note filed

The automatic and periodic sending of the data present in the memory is a decisive advantage, especially for so-called district services. This involves monitoring several objects by security personnel or by a guard who drives through and controls the objects to be monitored one after the other with a vehicle. The transmitter can be found here for sending out the data stored in the memory of the data collector in the vehicle. If the Guard has finished his inspection of an object, the data collector is placed in a holder, and automatically connected to the transmitter so that the data can now be passed on to the control center by radio. In the case of radio shadows - as mentioned - the transmission is repeated until it has been received by the control center.

The invention as a whole in a surprising way partially combines both features of the guard control as also the guardian protection with each other, with the totality of these characteristics to a completely new control system with the advantages mentioned. In the sense of guard control, the individual control points as before, but here the storan-

Replaced due and also very maintenance-requiring mechanics by electronics, the electronics also leads to the advantage that manipulations are practically impossible. Also with the invention of Thought of the guardian protection picked up, one if possible to be able to establish a quick connection to the headquarters in such a way that this basic idea also is not disturbed by any radio shadow that may be present. Thus, the new control system can, for example, also then can be used if the control points are in rooms shielded by metals (e.g. vault a bank). The invention thus eliminates the features of guard protection and guard control significantly improved.

Further advantageous refinements and expedient developments of the invention as well as that according to the invention Processes are specified in the claims and can be found in the drawing.

A serial interface 66 is also connected to the microprocessor 52 and, as the arrow 70 indicates, leads to the connector strip 46 or the transmitter 69. In addition, the data center 10 has an emergency call button 60 (the can also be used as an acknowledgment button), and A control connection to the transmitter 69 with a receiving part 71 can be established via a connection indicated by the arrow 68. The Memory 54 stored data are sent to a center, and it is also possible via the transmitter 69 through ,. . Pressing the emergency button 60 to make an emergency call.

The transmitter 69 with the receiving part 71 is normally

provided as a separate unit, for example in a vehicle of the security personnel, it is also possible to use the transmitter 69 with the data collector 10 as one Integrate unity. In the former case

\ - < ^v the data collector 10 can in a corresponding opening

Central office confirmation report on microprocessor 52.

In FIG. 9, a complete control system with subsequent evaluation via a data input 72 with a control center 74 is shown as a basic circuit diagram. The Ver-

- 23 -

Schieclen control points of an object to be monitored are formed by the data carriers 28 a - 28 g. The control posts can be accessed by security personnel using data collectors 10 a - 10 c can be queried and acknowledged.

Each data collector 10 a - 10 c stores the data read from the data carriers as well as the time and date. After completing a control round, the stored data are entered into a data input 72 and evaluated in a control center 74.

According to the principle block diagram in Fig. 10 comprises one Such a center has a charging station 80 with an opening into which the data collector 10 can be inserted. On the one hand, the electrical connection established in this way enables the operating voltage source of the data collector 10 can be charged, and on the other hand, the stored data can be called up and displayed on the screen 84 of a computer 82. Here can it is a conventional personal computer with a keyboard 86 and an attached printer 88. Thus, after the data collector 10 has been inserted into the charging station 80, a log is also printed out on the completed inspection round possible.

Appropriate software can be used to generate the report be kept in an easy-to-understand form.

-24-

Possible printouts are, for example: "South gate at

11 p.m. checked; North gate checked at 11.30 p.m.

Main entrance: none etc. ".

The center 74 also includes a radio receiver 76 with an antenna 78. In the case already described that - in the event of a radio shadow automatically at periodic intervals - the acknowledged data are to be transmitted ^{to the} center 74 by means of the transmitter 69, these data can be transmitted to the radio receiver 76 received and forwarded to the computer 82 are. Subsequently, the confirmation of the receipt of the data is sent to the respective data collector 10 (receiving part 71) by means of a transmitter (not shown).

It has already been explained with reference to FIG. 5 that each data carrier has a code strip 36 on which the data identifying the respective inspection body is applied. The data can be processed by individual magnetic bits are formed, which are spatially spaced from one another in a pattern on the code strife 36 are arranged. During the movement of the data collector 10 along the reading surface 32 of the data carrier 28, the data reading head 24 registers the individual bits, which are then digitally stored in the memory 54. The individual bits can be used in various known code forms, i.e. the numbers of the

- 25 -

respective control points are present on the code strip 36 in coded form.

In addition to the coding on a magnetic basis, the use of infrared light is also possible. In this case the reading surface 32 of the data carrier 28 consists of an infrared-permeable material. Behind the reading area are located - according to the digital signals "0" and "1" - materials that may or may not reflect the infrared light. In this case, the read head of the associated data collector consists of an infrared source with a receiver for the reflected infrared light.

Regardless of which type of coding is used, the control device according to the invention read the characteristics of a control point serially in a simple manner and store them in a memory. In conjunction with the microprocessor 52, FIG advantageously a wealth of possible applications and variants, which the control system is particularly make sure. For the first time, an "immediate" log printout is also possible via a control tour, whereby this log printout can be designed in any way using the appropriate software.
