Description

The invention relates to alarm systems, in particular, for the construction of the anti-theft system used to ensure the safety of goods put up for sale in the public domain. Such systems, when trying to steal goods, as well as in case of damage or disconnection of the system, generate light and sound signals.

Known anti-theft system for trading floors, ensuring the safety of goods put up for sale in the public domain. When you try to steal goods, as well as in case of damage or shutdown of the system, an alarm is triggered. The central control unit (CBU) processes information from alarm sensors. Each sensor is attached to the product and connected to the central anti-theft system through an expansion module using interconnect cables. Turning the CBU on and off is done with the help of the chip supplied in the set of theft protection equipment. An expansion module (PM) is required to connect the alarm sensors attached to the product with a central control unit. RM allows you to connect several security sensors. Universal alarm sensors are designed to arm objects that do not have a USB port (mobile phones, camcorders, cameras, MP3, audio and DVD players, communicators) and other small-sized electronic devices. Contact type alarm sensors are attached to each protected object by means of glue or a clamp. Through the expansion module, the security sensor is connected to the control part of the anti-theft system. Stands for sensors are rigidly mounted on the rack. The security sensor is held on a stand by a magnetic force sufficient to ensure that the goods are securely fixed on the rack, and at the same time allowing the buyer to freely remove it from the stand (EP 0516476, G08B 13/14, published 1992.12.02). Adopted as a prototype for both declared objects.

The disadvantage of this alarm is its lack of reliability due to the use of contact sensors of protection, which can be removed from the protection of the subject by closing the contact switch with an additional subject.

The present invention is aimed at solving the technical problem of changing the design of the security sensor and the design of the central control unit to ensure guaranteed operation of the sensor and the possibility of the alarm in the absence of a centralized power supply.

The technical result achieved in this case is to increase the security reliability of the anti-theft alarm system.

The specified technical result for the first embodiment is achieved by the fact that in the anti-theft system for goods displayed in the public domain, containing security sensors configured to attach to goods that are freely accessible to the buyer, said sensors are connected to at least one connecting cable a multi-channel expansion unit, configured to transmit the signal from the corresponding security sensor to the central control unit on each channel I, moreover, the expansion unit is configured to be connected to an additional multi-channel expansion unit, the central control unit is configured to be switched on from a mechanical key or chip and with the possibility of programming protection modes from the chip, the central control unit is configured to operate from a built-in autonomous power source when the centralized power system is turned off, the security sensors are made combined, and each of them is made in the form of placed in general orpuse registration unit capacity of the protected item and the recording unit illumination of the goods, each detection device attached to the commodity unit casing side, in which is situated responsive to illumination of the illumination element registration unit.

The specified technical result for the second embodiment is achieved by the fact that in the anti-theft system for goods displayed in the public domain, containing security sensors configured to be attached to goods that are freely accessible to the buyer, said sensors are connected to at least one connecting cable a multi-channel expansion unit, configured to transmit the signal from the corresponding security sensor to the central control unit on each channel I, moreover, the multi-channel expansion unit is configured to be connected to an additional multi-channel expansion unit, the central control unit is configured to be switched on from a mechanical key or chip and with the possibility of programming protection modes from the chip, the central control unit is configured to operate from a built-in autonomous source power when the centralized power system is turned off, the multi-channel expansion unit is configured to transmit signals from additional multi-channel expansion unit to the central control unit, and as security sensors, connecting cables are used that are inserted into the USB connectors of the goods to be protected and connected to the corresponding USB ports of the expansion module.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

The drawing shows a block diagram of the anti-theft system for the protection of goods displayed on the trading floor in the public domain.

The proposed anti-theft system (see drawing) according to the first performance example ensures the safety of goods 1 that are put up for sale to customers for sale in the public domain on the trading floor. When trying to steal goods 1, as well as in case of damage or shutdown of the system, an alarm is triggered (light 2 and sound 3). The electronic security system is able to work even in the event of a disconnection of the central power supply system, providing protection against theft in any situation. For this, the central control unit 4 (CBU) is configured to automatically connect to the autonomous power supply 5 (such as a battery) built into it when the voltage in the centralized power supply network drops below a threshold level or when the power is disconnected from this network. In case of disconnection of the external power supply, the control unit for the alarm sensors automatically starts to work from the battery, which is indicated by a light indication on the central panel. You can turn the battery on or off using a mechanical key.

Information from security sensors 6 is processed in the central control unit. Each security sensor 6 is attached to the product and connected to the anti-theft system central control unit via a multi-channel expansion module 7 using interconnect cables. The CBU can serve an unlimited number of security sensors. It has 8 line outputs for expansion modules (PM) with light indication. Turning the CBU on and off is done using a mechanical key or chip 8, which is supplied with the anti-theft equipment. The CBU is configured to program protection modes from chip 9. If there are several CBUs in the store, it is possible to program all the CBUs under one chip. The security system CBU is equipped with a remote light and sound indication. RM is necessary for the connection of security sensors attached to the goods with the Central Bank. RM allows you to connect up to 6 security sensors. The following information on the status of sensors is displayed on the RM using light indication:

- the facility is not under guard;

- the object is in guard mode;

- the object is in alarm mode.

PM can be assembled in a chain, the number of links is not limited. For this purpose, each RM is made with the possibility of joining an additional multi-channel RM. The multi-channel PM is configured to transmit signals from an additional multi-channel RM to the central control unit.

Universal security sensors are designed for arming objects that do not have a USB port (mobile phones, video cameras, cameras, MP3, audio and DVD players, communicators) and other small-sized, but expensive electronic devices. Security alarm sensors have a small weight and size and are attached to each protected object with a special sticker. Through the RM, the security sensor is connected to the control part of the anti-theft system. Stands for sensors are rigidly mounted on the rack. The security sensor is held on the stand by a magnetic force sufficient to ensure that the goods are securely fixed on the rack, and at the same time allowing the buyer to freely remove it from the stand. A stand, two stickers, and a mounting clamp are included with each sensor. The security sensor is performed combined with the function of simultaneously recording the capacity of the protected product and the illumination of this product. This sensor responds to a change in two parameters:

1) Capacities of the protected facility. When arming, the sensor measures the volume of the object (product) in contact with it and is triggered when the capacity of this object changes (removing any removable part of the product).

2) Illumination. At the moment when the sensor is attached to the object (product), the light does not fall on the LED mounted in the sensor. When the sensor is separated from the object, the illumination on the photocell changes and the sensor is triggered.

Each security sensor is made combined and each of them is made in the form of the capacity of the protected product and the illumination registration unit of this product located in the common case, and each security sensor is attached to the product unit by the side of the housing on which the light-sensitive element of the illumination registration unit is placed.

The security sensor has its own light indication, which informs about the state of the object under the alarm:

- the facility is not under guard;

- the object is in guard mode;

- the object is in alarm mode.

When the product is disconnected with the security sensor, its part responds to illumination and the part reacts to capacity change. Signals from the sensor through the PM are fed to the Central Control Unit, providing light and sound alarms. At the same time, indicators are displayed on the Central Bank and the RM indicating the communication circuit with the sensor in connection with which the operation occurred. The indicator also lights up on the sensor housing.

According to the second embodiment, the anti-theft system for goods displayed in the public domain contains security sensors made with the possibility of attachment to the goods that are exposed to the buyer in the public domain. These sensors are connected by connecting cables to at least one multichannel expansion unit, configured to transmit a signal from a respective security sensor to the central control unit on each channel, and the multichannel expansion unit is configured to be connected to an additional multichannel expansion unit. The central control unit is configured to be switched on from a mechanical key or chip and with the possibility of programming protection modes from the chip. The central control unit is configured to operate from an autonomous power source built into it when the centralized power system is turned off, the multi-channel expansion unit is configured to transmit signals from an additional multi-channel expansion unit to the central control unit, and connection cables inserted into USB are used as security sensors connectors of the goods to be protected and connected to the corresponding USB ports of the expansion module.

In the anti-theft system according to the second example of execution, the PM is made with USB ports in the number of channels that are connected via cables to the USB connectors of the protected goods that are equipped with a USB port (laptops, printers and other portable office equipment). In this embodiment, the connecting cables for the USB ports act as security sensors. This system functions in the same way as described previously, but reacts to a disconnection via USB.

The present invention is industrially applicable. It can be manufactured using well-known tools and technologies used in the manufacture of burglar alarms.
