Description

 The invention relates to techniques for protecting objects from unauthorized access by unauthorized persons, and more particularly to security alarm systems using a mobile radio cellular telephone, and can be used to protect vehicles, residential premises, offices, warehouses, safes and other objects.

 A known method of burglar alarms and devices implementing it using a telephone subscriber network (see RF patent N 2065256, IPC H 04 M 11/04, publ. 10.08.96). In the known method, when the security sensor is triggered, an alarm signal is generated, by which the telephone line is occupied and the call signal is transmitted to the notified subscriber, and after establishing a connection with the notified subscriber, an alarm signal is transmitted to him. Moreover, before occupying the telephone line, it is occupied for a short time and released in order to unlock the telephone set in case of violation of its security functions by violators. The disadvantages of this well-known solution include limited functionality, due to the limited range of protected objects to only stationary ones, to which the telephone line of the city telephone network is connected, as well as the insufficient protection efficiency, due to the possibility of breaking the telephone line by intruders.

 There is also a device for protecting residential premises from burglary (see German application laid out N 4438848, IPC H 04 M 11/04, publ. 05/18/95), which is a regular telephone that receives pulsed signals from various sensors that control automatic dialing or dialer. After establishing a connection with the notified subscriber, the voice message reproducing device automatically starts, which reproduces the previously recorded message until the notified subscriber hangs up the telephone.

 This known device also has the disadvantages mentioned above.

 A known method of preventing hacking and / or theft in relation to moving objects using a mobile phone and a hack sensor. laid out. application of Germany N 4442807, IPC H 04 M 11/04, publ. 06/05/96). In accordance with the known method, the hacking sensor, when activated, activates a mobile phone that dials a predetermined number. In a preferred embodiment of the known method, the telephone is a telephone mounted in a car that is connected to a conventional car alarm system. When the alarm is triggered due to hacking, the phone automatically dials the phone number pre-programmed by the owner and gives him a warning signal. The owner can take appropriate action in a timely manner (for example, call the police). The disadvantages of this known method include all the disadvantages inherent in car alarm systems, the ability to work only with car alarm systems, the lack of voice communication, the inability to control from another phone, in addition, the direct purpose of the mobile phone as a phone is lost.

 A remote control device is known (see EP 0909083 A1, IPC H 04 K 11/04, publ. 04/14/1999), containing sensors of various parameters of the protected object (penetration sensors on doors, windows, noise sensors in the room, smoke, etc. p.), connected to the evaluation unit, issuing an output signal in the case when the readings of the sensors indicate the presence of a deviation from the normal state. The output signal of the evaluation unit is used to control a mobile phone, which is programmed so that after establishing a connection with a second mobile phone, located at the owner of the guarded object, first it generates a transmitter identification signal stored in advance. Thus, the owner is notified that there is an emergency situation at the protected object that requires the intervention of the owner. This known device can be used to control moving objects, for example, patients. In this case, other types of sensors are used (pulse, ECG, skin moisture, etc.), which, when deviations of any parameters from their normal values are registered, activate a mobile phone located at the controlled object to alert service personnel and provide timely assistance to the patient.

 This well-known device provides effective control of objects, however, it is quite complex, it requires significant refinement of the mobile phone itself. In addition, voice message transmission is not provided, there is no possibility of control from another phone and the direct purpose of the mobile phone as a telephone is lost.

In addition, the inclusion of a mobile phone in security mode can be carried out remotely using a remote control, preferably with a delay.

 The specified technical result is also achieved by the fact that the electronic security device corresponding to the second embodiment and containing at least one intrusion detection sensor designed to be placed on the guarded object, a mobile phone designed to be placed within the guarded object, is programmed to make a call to the set number the subscriber when the at least one penetration detection sensor is triggered, in accordance with the invention, an additional but - contains a switching unit intended for placement on a guarded object and containing a command-time device programmed to control a mobile phone, a device for recording and reproducing a voice message, a code recognition device and an autonomous power supply unit, while at least one penetration detection sensor is mentioned connected to the information input of the switching unit, connected, preferably through a receiver of sensor signals, to the first information input command - a temporary device, the outputs of which are connected respectively to the activation input of the mobile phone and to the input of the start of the device for recording and playing voice messages, the output of which is connected to the input of the voice message transmission of the mobile phone, the input of the code recognition device is connected to the tone output of the mobile phone, and the output is with the second information input of the command-temporary device.

 In this case, the electronic security device in both versions preferably has a remote control connected via a wireless channel to the control input of the switching unit. The control input of the switching unit through the receiver of the remote control signals and, if necessary, through the delay unit, is connected to the on-off input of the guard mode of the command-time device.

 The autonomous power supply unit in the second embodiment has a mains charging input connected to the mains power supply unit, an autonomous power supply output connected to power inputs of the command-temporary device, a voice message recording and reproducing device, a code recognition device and said receiving devices, and an initiation output the programmed sequence of warning cycles when the power supply network of the protected object is de-energized, associated with the third information input of the command-temporary device.

The invention is illustrated by the example of its implementation, illustrated by drawings, which show the following:
FIG. 1 is a block diagram of an electronic security device made in accordance with the invention,
FIG. 2 is a graph of the operation cycles of the command-temporary device in the alert mode.

 As shown in FIG. 1, the electronic security device contains sensors 1 for detecting intrusion (intrusion, hacking, theft) located on the guarded object, a mobile phone 2, a switching unit 3, a power supply unit 4. The power supply unit 4 provides the connection of the switching unit 3 to the network of the protected object (external power source) with a voltage of 220 V or 12 V. The device also contains a remote control 5.

 The switching unit 3 constructively combines a command-time device 6, a device 7 for recording and playing back a voice message, an autonomous power supply unit 8, a receiving device 9 for signals of sensors 1 for detecting intrusion, a receiving device 10 for signals from a remote control 5 (remote control), recognition device 11 code and block 12 delay arming. In possible embodiments, the electronic security device may lack a code recognition device 11 and / or an arming delay unit 12, which will be described in more detail below.

 As sensors 1 for detecting penetration, loop devices, infrared radiation sensors, noise threshold sensors, contact, magnetic, and other sensors can be used. The autonomous power supply unit 8 ensures the operation of the electronic security device without connecting to an external power source (power supply network of the protected facility).

 After installing the security device on the protected object, the user or the person guarding the object records in the memory of the device 7 for recording and playing back a voice message a message text that will be automatically transmitted to a predetermined subscriber, for example, to the owner of the protected object, if an intrusion is detected using sensors 1. Possible an embodiment of the invention, when using a mobile phone with an answering machine, as a device for recording and playing back a voice message, so use mobile phone voice mail.

 An electronic security device is placed in a guarded facility secretly or in an inaccessible place in order to prevent violators from blocking its security functions. This does not cause problems due to the possibility of using an autonomous power supply unit 8 that is not connected to the power supply network of the protected object in the security device. In this case, the user should only timely charge the security device. When connected to the mains network of the protected object, the autonomous power supply unit 8 is in recharging mode and monitors the presence of mains voltage (the latter function can be turned off).

 Electronic security device operates as follows.

 The device can be armed in the remote control mode using the remote control 5, the signal of which is received by the receiver 10 of the remote control signals generating the security mode enable signal, which is supplied in this embodiment via the security mode enable delay unit 12 to the temporary command device 6. Use block 12 delay eliminates false alarms of intrusion detection sensors when using the remote control 5 remote control, whose range is limited by the range of direct visibility, ka to the case of widely used infrared remote controls. In this case, after the security device is turned on, the user can leave the guarded object (apartment, cottage, office, etc.) without fear of causing false alarms of the intrusion detection sensors 1 during the set delay time of the delay unit 12. When using remote controls using a different operating principle operating in a different range of ranges, the use of delay unit 12 may not be necessary.

 When the sensor 1 is detected intrusion detection, the output signal of the sensor 1 is supplied to the receiving device 9 of the sensor signals. The received signal after processing in the receiving device 9 is fed to the first information input of the command-temporary device 6 and initiates the sequence of cyclically repeated operations (notification cycles) programmed in it. In FIG. 2 shows the operations of one cycle, according to which the command-time device 6 sends a signal equivalent to pressing the "SND" button to the mobile phone 2, which switches it into the automatic redial mode by the pre-recorded phone number of the subscriber, for example, by the number of the owner of the protected object. When establishing a connection with the subscriber to the command-temporary device 6 receives a response signal from the subscriber generated by the mobile phone 2 when establishing a connection. According to the response signal of the subscriber, the temporary command device 6 includes a device 7 for recording and reproducing a voice message. The transmitted voice message is listened by the notified subscriber. When using a mobile phone with an answering machine, the response signal of the subscriber through a command-time device 6 turns on the answering machine of the mobile phone, the message of which is being listened to by the subscriber. Alternatively, when using both an answering machine of a mobile phone and a device 7 for recording and playing back a voice message, if necessary, the function of the answering machine can be turned off, in which case the transmission of a voice message is carried out only by the device 7. The auto-dialing and transmission of voice messages is carried out during the first predetermined time interval of duration, for example, 1 minute (Fig. 2). After this time interval the command-time device 6 sends a signal to the mobile phone 2, equivalent to pressing the END ("end") button. In this case, the mobile phone 2 goes into standby mode for incoming calls during the second predefined interval of, for example, 15 seconds (Fig. 2).

In this embodiment, during the second predetermined interval, an incoming call from one telephone (for example, from the telephone of the notified subscriber) to the mobile phone 2 transmits a signal from one of the predefined codes. This signal received by the mobile phone 2 is supplied to the code recognition device 11. When recognizing the received code, the code recognition device 11 generates a signal corresponding to this code, transmitted to the second information input of the time-command device 6. The time-command device 6, depending on the type of signal from the code recognition device 11, performs the following:
- interrupts the initiated sequence of operations (execution of notification cycles) and sends a signal to the mobile phone 2, l equivalent to pressing the "END" button ("end"), and transmits a signal to turn off the device 7 recording and playback of voice messages, as a result of which the device goes into object security mode, or
- transmits to the mobile phone 2 a signal equivalent to pressing the "SND"("transfer") button, thereby achieving a connection with the subscriber’s telephone, and transmits a signal to turn off the device 7 for recording and playing back a voice message, as a result of which the device enters the listening mode of the subscriber object.

 The security device is transferred from the listening mode to the object's security mode automatically when the subscriber stops listening, interrupting communication. In this case, the mobile phone 2 transmits a hang-up signal generated during interruption of the connection to the code recognition device 11, which generates a signal to transfer the device to the security mode of the object and transmits it to the temporary command device 6, which transmits to the mobile phone 2 a signal equivalent to pressing the END button ", while the device enters the security mode of the object.

 If during the second predetermined interval of the notification cycle no incoming calls were received, then after the specified interval of time the command-time device 6, by applying the "SND" signal, initiates the next notification cycle. The notification cycles will be repeated until, during the second predetermined interval of the next running notification cycle, a signal from one of the aforementioned predefined codes is received with an incoming call.

 In a possible embodiment of the invention, the function of transmitting signals of predetermined codes with an incoming call may not be used, and therefore, the code recognition device 11 may be absent. In this case, the response signal of the notified subscriber arrives at the time-command device 6, which includes the device 7 for recording and playing back the voice message, and the transfer to the protection mode is carried out by the subscriber's incoming call during the second predefined time interval.

 When the power supply network of the protected object is de-energized, the autonomous power supply unit 8 automatically switches from recharging mode to power mode and sends a signal to the third information input of the command-temporary device 6, which is equivalent to the operation signal of the intrusion detection sensor 1, which initiates the programmed sequence of operations described above, with transmission the same voice message. This function is preferable for the protection of moving objects and can be disabled by the user.

 When disconnecting the mobile phone 2 from the switching unit 3, the mobile phone can be used for its intended purpose. In the unconnected state, the use of the mobile phone is limited by the length of the connecting cable of the mobile phone 2 with the switching unit 3, i.e. in this case, for ease of use, the mobile phone is stationary.

 In one of the possible embodiments of the invention, the electronic security device can be made in the form of a car security device. The device is placed in one radio-transparent housing and is installed, for example, in the trunk of a car. The electronic security device can be connected directly to the car alarm system and the car’s power supply network. In this case, a hacking, theft signal is sent to the device not from intrusion detection sensors, but from the car alarm system. When using the security device autonomously in a car (without connecting to a car alarm system), it is advisable to install intrusion detection sensors to detect unauthorized opening of trunk lids, engine compartment, and doors. If the device is connected to the vehicle’s power supply, the autonomous power supply will also respond to the removal of the battery, as in the case of a blackout of the power supply of the guarded object described above. Turning on the car security device in the security mode and turning it off can be done from the car alarm remote control, from the remote control of the security device itself and the code transmitted with an incoming phone call from any phone.

 The operation of the security device mounted on the vehicle is similar to the operation described above. The design of the security device mounted on the vehicle and connected to the car alarm system differs only in the absence of intrusion detection sensors 1.
