Description

Device for signaling the theft of a computer, office or household

electronic technology

The utility model relates to security means signaling theft during pickup or other attempts to move computer, office or household electronic equipment.

Among security devices, for example, the “Alarm sensor according to the patent of the Russian Federation No. 2006948, d. Publ. 01/30/94, IPC 5 G08B 13/14, containing a housing in the form of a cap, a screw element with a suspended inertial mass of the pendulum, a polarized piezoceramic element coaxial with them in the form of a hollow cylinder. When trying to lift or shift a protected object, the inertial mass of the pendulum changes its position, striking the inner surface of the piezoelectric element, as a result of which mechanical energy is converted into electrical energy. However, such a device is technically difficult in view of the need to reconcile the positions of the pendulum and the piezoelectric element when installing the device.

It is known "Device for signaling theft according to the patent of the Russian Federation No. 2087034, d. Publ. 08/10/97, IPC G08B 13/14, designed to prevent theft of small safes and containing a power source located inside the safe, connected through the spring contacts of the switch to an acoustic transducer, and between the contacts

of the circuit breaker, an insulating key in the form of an elastic tape was inserted through the rollers through the slot in the safe chamber and sealed with the other end on the anchor in the floor. When you try to steal, the tape of the insulating key comes out of the switch contacts, the closure of which leads to the operation of the acoustic transducers. However, among the disadvantages of this decision should be attributed to the unacceptability of sealing any elements of the security device into the floor when placing computer, office and household electronic equipment. And in addition, due to operational and aesthetic requirements, the free placement of such equipment in a puberny or residential building usually involves gaps between this equipment and the walls, floor, which, when using the security device according to patent No. 2087034, will allow you to disconnect the tape from the anchor without affecting the electrical circuit of the device that appears to be unacceptable in case of theft.

The closest analogue of the claimed utility model is “Security alarm device according to the patent of the Russian Federation No. 2031445, D. publ. 03.20.95, IPC b G08B 13/16, G08B 29/18, designed to protect cars, motorcycles, garages, doors, windows, balconies, safes and containing a vibration sensor, a signal filter, signal transmission lines, signal amplifiers, a break sensor , lines for detecting an open circuit, output driver, alarm output unit, pulse generator, regulating and limiting resistors, isolation capacitors, host identification code receiver, control unit, detector unit, drive, comparator, extension cord An LED with a busbar is convenient for observation. Moreover, in

in the case of protection of electronic equipment, under normal conditions not subject to external vibration, the prototin device is too complicated, unacceptable long-term accumulation of a signal exceeding the average level of the vibration environment.

The purpose of the claimed utility model is to simplify the design of the device with the ability to be embedded inside the protected electronic equipment, to prevent the security device from triggering when the owner plans to move the computer or other equipment related to computer, office or household electronic equipment.

The device for signaling the theft of computer, office or household electronic equipment contains a power supply in the form of a battery and a charger, a key for mechanical or electrical rupture of the device’s power circuit, a vibration switch on, an electronic on / off switch with a timer, a signal amplifier, an audio signal generator in the form of a siren.

The device is placed on the surface of the enclosures or inside computer, office or household stationary electronic equipment, the speakers of which can be built into the device as an element of the sound generator of the device for signaling.

In fig. 1 shows a structural diagram of the device, in Fig. 2 shows an electrical diagram of a device.

A device for signaling the theft of computer, office or household electronic equipment (Fig. 1) contains a power supply in the form

battery 2 and charger 1, a key 7 for mechanical or electrical interruption of the device’s power supply circuit, a vibration switch 5, an electronic on-off switch with a timer 3, a signal amplifier 4, an audio signal generator (siren) 6. When an attempt is made to steal, during unauthorized lifting or moving of protected electronic equipment, a vibration sensor 5 is triggered, which closes the device’s electrical circuit, which leads to the operation of the sound generator 6 (siren). The sound produced by the device attracts the attention of others and prevents theft. At the same time, when the transfer of a guarded device related to electronic equipment is authorized by its owner, an open circuit key 7 interrupts the power supply of the device and prevents the device from being triggered untimely. When placing the device inside electronic equipment, the key 7 is displayed on the external panel of the protected device.
