Description

The inventive utility model relates to devices for preventing unauthorized entry into an object, that is, to devices that ensure receipt, transmission and presentation to a consumer of information about illegal entry into protected objects, for example, apartments and other similar real estate objects, and can also be used on vehicles . In particular, the claimed utility model relates to devices using a GSM cellular communication system.

A device for transmitting alarming information about the state of the object (patent RU No. 4022 according to class IPC ⁷ G08B 25/10, publ. 04/16/97).

The device can be used to protect objects from unwanted phenomena, in particular, it can serve as a security device for real estate (apartment, cottage, garage, etc.) or vehicles. The device includes alarm registration sensors and radio communication equipment of these sensors with alarm receivers. Radio communication equipment is made in the form of a cellular communication system. Alarm receivers are located at specialized facilities located, for example, in the private security service. At the same time, an additional receiver is located at the cellular subscriber.

A known radio-channel alarm system (patent RU No. 2242383, class IPC ⁷ G08B 25/10, publ. 12/20/2004), which performs the function of a security device and carries out the receipt, processing, transmission and presentation to consumers of information on penetration of real estate or on guarded vehicles. The system contains a security alarm system installed at the guarded facility. The complex includes detectors, a control panel containing a memory unit and a processor, security sirens and programmable modules for transmitting alarm messages. There is also a notification transmission system with a terminal device, a cellular communication network and a user subscriber terminal. The user's terminal device and subscriber terminal are GSM standard mobile phones made with data transmission capabilities in SMS and / or GPRS modes.

Also known is the alarm system of motor vehicles and real estate (application RU No. 2004137208, class IPC ⁷ G08B 1/00, publ. 05.27.2006). It is also capable of performing the function of a security device and contains blocks of security annunciators, consisting of sensors of unauthorized intrusion, and transmitters associated with the base station. The base station is a receiver with an antenna for

communication over the air. One of the transmitters can be installed on a guarded object, and the corresponding receiver is located at the owner of this object. The receiver and transmitter are connected via a cellular communication standard GSM or the like.

These well-known technical solutions have the advantage that, due to the availability of cellular communications, information about an alarm event goes directly to the user, who makes the corresponding decision. However, they have several disadvantages. Firstly, this is a large list of technical equipment included in the alarm systems. Secondly, they are very difficult to implement and, thirdly, they require high financial costs.

A device for remote burglar alarm is known (patent RU No. 56661, class IPC ⁷ G08B 25/08, published September 10, 2006) containing a cell phone, on the board of which two conductors are soldered to the contacts of one of the buttons, to which a backup button is connected. Duplicate button is used to set up the phone. In parallel with the backup button, a button is installed that is installed in the doorway of the apartment and works to close when the door is opened. The device has a switch that is used to turn off the button that works on the circuit.

The disadvantage of this device is the need for structural changes to the mobile phone.

A known security system (WO No. 2005/013222 according to class G08B 13/08, published 03.08.04), in which a mobile phone, cordless telephone or portable transceiver is installed in a case. The front panel of the case has a hole with a rod placed in it, one end of which is located opposite the send button. This button is preprogrammed to the called party number. The device is installed on the floor, behind the door of the guarded object. When opening the door, the end of the rod presses the “send” button, which leads

to call a pre-programmed number. Compared with the previously described technical solution, this device does not require structural changes of the mobile phone, it is quite simple to manufacture, but unreliable, since it implements the mechanical principle of interaction between the bar and the button. Then, if the door is not opened enough, the contact between the bar and the door may not occur, and, therefore, such a device will not prevent unauthorized entry.

Also known is a cellular security alarm system for the door of an object (patent RU No. 60762, class G08B 25/10, publ. 01/27/07), which is adopted as a prototype. The device includes a signal cell phone, which is installed on the object. This phone is associated with a pre-programmed subscriber's cell phone number. The signal mobile phone is equipped with a call key mechanism. The key pressing mechanism comprises a lever with a protrusion, a rod made of polymer thread or a rigid knitting needle, which is connected with the lever. A collet with an internal protrusion is fixed at the second end of the rod, and a rod with a head is fixed to the door of the protected object. A rod with a head enters the collet, moves it apart, the head extends beyond the inner protrusion. When the door is opened, the polymer thread is tensioned, the push mechanism is activated, and a call is made from the signal cell phone to the subscriber's cell phone.

This device has several advantages, which are that it is easy to manufacture and does not require large financial costs. However, it has significant disadvantages:

- low reliability, since the push mechanism is mechanically actuated by means of a rod for which a thread or a rod is used, and the probability of damage to such a rod is high enough;

- such a device should be fixed permanently, not far from the door, i.e. it has a location restriction determined by the length of the thrust (polymer thread).

The task is to create a security alarm system for the door of the object using a cell phone, which allows to achieve a comprehensive technical result:

- significantly increase the security of the facility,

- to increase the efficiency of object security while ensuring maximum convenience.

This technical result is achieved due to the fact that the well-known cellular security alarm system of an object door containing a signaling cellular telephone equipped with a telephone keypress mechanism and connected via a cellular communication network to a subscriber’s cellular telephone according to this utility model further comprises a warning signal sensor designed to for placement on the door of an object, a contact element and an electromagnet, which are structurally combined with a signal cell phone and a mechanism on a key press of the specified telephone, and an electromagnet power supply, wherein the contact element is arranged to interact with the key-pressing mechanism of the cell phone, and the alert signal sensor is configured to affect the key-pressing mechanism of the signal telephone by means of an electromagnet.

This implementation of a cellular security alarm allows you to achieve technical results: to increase the reliability of the cellular security alarm system of an object’s door and increase the reliability and efficiency of object security while providing maximum convenience. This is due to the fact that the inventive cellular security alarm system door of the object, in comparison with the prototype, contains a warning signal sensor and structurally combined contact element, which can be made in the form of a permanent magnet, an electromagnet and a signaling cell

a telephone with a keystroke of said cell phone. In the inventive device, the keystroke is not mechanically actuated, but using remote electromagnetic exposure, which significantly increases the reliability of the cellular security alarm.

In addition, as a mechanism for pressing the keys of the signal telephone, a strap is used, which should be made of metal. The bar is a two-arm lever, the first shoulder of which interacts with the contact element, and the second shoulder with the electromagnet. This embodiment of the keypress mechanism of the signal telephone, using electromagnetic effects on the keypress mechanism, increases the reliability of the device.

In addition, the alert signal sensor is a permanent magnet for installation on a guarded object and a switching reed switch for installation on a guarded object in the area of the permanent magnet. This embodiment of the warning signal sensor ensures the reliability of the cellular security alarm, since the warning signal sensor about unauthorized entry is triggered only in case of a magneto-magnet and reed switch disturbance.

The inventive device, compared with the prototype, has significant differences, which are that:

- the use of a warning signal sensor, a contact element and an electromagnet allows you to abandon the unreliable mechanical principle of the mechanism of pressing the keys of the signal telephone and to implement the remote electromagnetic principle of communication between the elements of the device,

- structurally combined contact element, an electromagnet and a signal cell phone with a keypress mechanism of the specified phone are placed where it is convenient for the owner. As a result, in comparison with the prototype, there is no need for a stationary installation of a signal

a cell phone with a keypress mechanism close to the door of the guarded object, which ensures maximum ease of use.

The technical essence of the utility model is illustrated by drawings, where

figure 1 - block diagram of a cellular security alarm system door of the object,

figure 2 - holder for a signal cell phone,

figure 3 is a view along arrow A,

4 is an embodiment of a utility model.

The inventive cellular security alarm system (Fig. 1) contains a warning signal sensor 1 located on the guarded object, made in the form of a permanent magnet 2, which is fixed on the door of the protected object, and a reed switch 3, which is fixed on the fixed part of the door or on the wall. The switching reed switch is used as a reed switch. In addition, the cellular security alarm system contains a signal cellular telephone 4. In this case, for example, a NOKIA telephone of the 3310, 3340, 3350 series can be used. The telephone is placed in the holder 5 (FIG. 2), which should provide a rigid fixation of the cellular telephone and can have a different design. Figure 2 schematically shows one of the possible embodiments of the holder. The phone is placed on the base screws 6 and fixed in the holder using the fixing rods 7 and the base tabs 8 (Fig.2 and 3). Security alarm (figure 3) has a keypress mechanism, which is a bar 9, made, for example, of steel. The strap is a two-arm lever fixed on the cell phone holder with screws 10. It has two rods made, for example, in the form of screws 11 and 12, in contact with the keys 13 “reset” and 14 “quick call”, respectively. An electromagnet 15 is attached to the holder 5 of the cellphone 4, from the side of the battery charging port of the specified phone. The contact element 16, which is a permanent magnet, is attached to the opposite side of the holder 5.

Signal cell phone 4, located in the holder 5, a permanent magnet 16 and an electromagnet 15 mounted on the holder, a power supply 17 for the electromagnet 15 and a charger for the phone (not shown) can be placed in the housing (not shown), made, for example, in the form of a corrugated PVC pipe used for laying cable networks. On both sides of the pipe is closed with plugs, in one of which holes are made for the output of electrical wires. The case is placed at the guarded facility where it is convenient for the owner, it can be placed secretly or in an inaccessible place in order to avoid blocking its security functions by violators.

The device operates as follows.

Install the alarm sensor 1. To do this, a permanent magnet 2 is fixed on the movable part of the door of the protected object (for example, an apartment) 2. On the fixed part of the door or on the wall, in the area of magnet 2, a reed switch 3 is installed, for example, KEM-3 or ISS 27301. By means of electric wires, the reed switch 3 is connected with an electromagnet 15. A power supply unit 17 provides the connection of an electromagnet 15 to the power supply network of a guarded object (external power supply) with a voltage of 220 V or 12 V (not shown in the drawing). To ensure uninterrupted operation, a battery can be used in the power circuit of the electromagnet 15, while the battery switches from charging mode to power mode when the power supply to the protected object is de-energized. With the door closed, the electromagnet 15 is de-energized. In this case, the strip 9 is in contact (attracted) with a permanent magnet 16 (arrow b, Fig. 3) and the screw 11 presses the reset button 13. When the door is opened, the magnetic flux changes through the reed switch 3, and the voltage is supplied to the electromagnet 15. The bar 9 is attracted to the electromagnet 15 (arrow c, Fig. 3), the screw 12 presses the “quick call” key 14, and a pre-programmed cell number is dialed subscriber's phone (not shown in the diagram). For the specified phone models, the key

14 “quick call” is triggered if the time of its pressing exceeds 2 seconds, i.e. almost instantly triggering the "quick call" key.

To expand the range of mobile phones that can be used to implement this technical solution, an electromagnet can be used as a contact element 16. Figure 4 shows an embodiment of a utility model using an electromagnet as a contact element 16. This option is used for those phones for which the “reset” function and the “on - off” function are performed by the same button. The positions in the drawing of figure 4 are indicated:

3 - reed switch

9 - bar,

15 is an electromagnet,

16 - contact element (electromagnet), 18 - diode, 19,20 - relay,

21 is a capacitor

22 - transistor,

23, 24, 25 - resistors.

In this case, the device operates as follows. The door is open. In this case, the contacts d and e of the switching reed switch 3 are closed. The voltage of 12 V is supplied to the electromagnet 15 (a call signal is ringing) and through the diode 18 to the winding of the relay 19. In this case, the first pair of contacts 19 _{1 of the} relay 19 closes, and the second pair 19 ₂ - opens. Relay 20 is thus de-energized. Thus, the relay 19 will be constantly on, regardless of the state of the reed switch 3, until the relay 20 is activated. When the door is closed, the contacts d and f of the reed switch 3 are closed. In this case, the capacitor 21 is slowly charging through the resistor 23 - this is necessary so that the call signal has time to reach the addressee. The positive voltage at the base of transistor 22 is increased. About

after a minute, the transistor 22 opens, turning on the relay 20. The first pair of contacts 20 _{1 of the} relay 20 will close, applying a voltage of 12 V to the electromagnet 16, the second pair of contacts 20 _{2 of the} relay 20 will open, and the relay 19 will be de-energized. The first pair of contacts 19 _{1 will} open, and the second pair 19 ₂ will close, discharging the capacitor 21 through the resistor 24. The positive voltage at the base of transistor 22 will quickly decrease, and the transistor will close, de-energizing relay 20. The first pair of contacts 20 _{1 will} open, disconnecting the electromagnet 16. The diode 18 is needed so that the electromagnet 15 is not constantly energized from the side of the relay 19. The resistor 24 is selected so that the electromagnet 16 is turned on for a period of not more than 1 s, otherwise the phone will turn off.

Cellular burglar alarm can be made in the form of a car security device. In this case, the power circuit of the electromagnet 15 is included in the electrical circuit of the car, specifically in the power circuit of the interior lighting bulbs. The alarm system installed on the car is similar to the operation described above. The design of the security device installed on the car and included in the electric circuit of the car differs only in the absence of a warning signal sensor, however, a circuit with a sensor can also be used.

This cellular alarm can be used not only as a security alarm, but also to control deviations of various parameters from their normal values in various production processes, for example, to control deviations of temperature and water pressure in boiler pipes.

The proposed technical solution also has the advantage that it requires insignificant financial costs for implementation, since a simple and cheap mobile phone with a minimum set of functions, the cost of which is low, is used as a signal one.
