Description

Method and system of remote control and control of an object, in particular a guarded vehicle.

Technical field

The invention generally relates to a method and system for remote control and control of a guarded object, in particular a method and system for guarding buildings, country houses and tracking stolen vehicles.

BACKGROUND OF THE INVENTION

The means of remote control and control control events and actions of a defined scope. The guarded object may be moving or immovable objects, characterized as forming part of the property of a certain value, which may become subjects of illegal activities of unauthorized persons, i.e. vehicles may be illegally appropriated, used illegally, thieves may break into buildings, etc.

In practice, several protection systems have been developed to prevent, or at least make this illegal action more difficult, by using the latest knowledge to overcome various, increasingly new and increasingly unlawful acts.

In addition to the means commonly called thief protection, the control of various catastrophic events has gained in importance due to its great importance, along with the ability to counteract these events effectively, which in most cases has been done by extending, obviously partially, systems primarily against thieves.

Given the increasing number of acts of violence, it is difficult to rely on the effective intervention of the non-involved, present as eyewitnesses of these acts, and the working methods of professional protection organizations.

For this purpose, remote control of the guarded buildings, using for this purpose primarily existing communication systems corresponding to the objectives considered to be of primary importance, became the most important.

EP 0 366 378 A2 and US 5 276 728 disclose a remote connection by means of a mobile phone or other telecommunication means between a vehicle sensor and an alarm device. When entering a vehicle, the protection is provided not only by issuing the usual acoustic and optical signals and by blocking the ignition, but further information-operative protection is also provided by the mobile telephone placed in the vehicle by dialing the given telephone numbers. The owner or user or other control or protection center may receive burglary information, hear offenders and send off deterrents, or may even decide to stop a stolen and moving vehicle by interrupting its ignition circuit or other electronic control unit. The disadvantage of all these activities is that these relatively simple faults can be eliminated even by less experienced ones, today's car thieves - unfortunately - usually have deep professional knowledge.

For all solutions related to a public telecommunications system, the serious problem in the operation and operation of such a system is that it is not always possible to get an uninterrupted and instantaneous connection in peak traffic. Such possible and momentary outages cause serious difficulties both in remote control and driving, i.e. immobilization of the vehicle, and, depending on the protective system used, may temporarily prevent the owner from getting into his own vehicle.

EP 0 242 099 A2 describes an anti-theft system and a location identification system where the current position of a protected object, in particular a vehicle or person, is given by the coordinates provided by a microprocessor system called Navstar Global Positioning System, GPS. When activated by, for example, unauthorized opening or starting or changing the position of the vehicle, the microprocessor will automatically log on in • · · · • 9 • ·

Information about the current location of the protected object is periodically refreshed by occasionally transmitting a sequence of digital signals to the central control center via a mobile phone. The central control center is also able to call the microprocessor by retrieving its individual identification number and the central control center is able to determine the location of the vehicle if the vehicle has been moved without activating the microprocessor protection system. Of course, the system is provided with several logic inputs and outputs, to which transmitters and signal sensors and acoustic and optical alarm output devices, known in the field of alarm technology, can be connected and includes such control devices that can be activated by a protected vehicle also using a mobile phone system , thereby causing or disabling the operation of the protected vehicle, simply by introducing the malfunctions into the function of the vehicle, or stopping it, while respecting the safety requirements of the operation. This arrangement does not exclude the possibility of using a so-called purpose-oriented device suitable for performing only the required functions instead of the so-called normal telephone available on the market.

EP 0 449 471 A2 proposes the integration of mobile phones into a vehicle security system using interconnection means through which a number of different commercially available mobile phones and different vehicle alarm systems can be connected. The interconnecting means comprises a control means and an interconnecting means for connecting the mobile phones to the control means. These interconnection means comprise a data library stored in memory for storing the individual protocols required for communication with the various mobile phones, and the system operator makes the mobile phone and the alarm system mutually adapt during the system activation. The primary objective of this system is to use the mobile phone of the vehicle to remotely guard the vehicle, to indicate unauthorized events • · · · • 9

In both of these documents, remote guarding of the object (s) consists of a specific control of the guarded object - moving property or real estate - which is supervised either continuously or periodically and triggers a change in a given character or scope - ie in the event of unauthorized intrusion. a local alarm and telecommunication equipment is sent a remote alarm or information message to a given address, or the location of the object given by its coordinates obtained from the reference system and after the local alarm is sent, or the faulty operation or unmanageability of the guarded object furthermore, by means of a remote control made from an informed address, the guarded object is or may be brought into a state of partial or total unmanageability.

Although none of these documents emphasizes this, the operational steps initiated by unauthorized intrusion do not represent even one percent of the overall operation of the protection system. In the vast majority of cases, the emergency state is also intentionally canceled by remote control, for example when the owner returns to the vehicle. This simultaneously represents the Achilles heel of the system, namely the technology available today enables people - without much effort for those who specialize in this way of making money, to obtain a remote control code or to create a series of known remote control codes serially - to turn off the system from activity.

EP 0 778 184 discloses an anti-theft device for preventing the vehicle from operating in the event of an theft attempt. A switch is located in the ignition circuit. The switch is controlled by a remote control processor and interrupts the ignition circuit and prevents current flow through the circuit. Thus, this switch is operable irrespective of the vehicle in operation, thereby rendering the vehicle inoperable even after it has been found to have been taken by a thief.

GB 2 279 478 discloses a safety device placed in a vehicle comprising; an external GPS detector antenna, an internal backup antenna and vehicle position receiver circuit, an interference detector for detecting vehicle interference and an external mobile phone antenna, an internal backup antenna, and a combined transmitter receiver for transmitting vehicle position and interference status information.

US 5 223 844 discloses a vehicle tracking and safety system allowing immediate response in the event of a vehicle theft, accident, vehicle failure or other emergency. Surveillance and tracking functions are provided by mobile units located in hidden places in the vehicles being checked. The mobile units are connected to the control center. Preferably, the mobile unit provides protection against theft and intrusion into the vehicle using an in-vehicle alarm and security system coupled to the control center via a combined transceiver in the mobile unit. A keyboard or other personal interface device is also used to allow the driver or vehicle user to signal to the control center that he needs some kind of assistance. The vehicle position can be automatically sent to the control center along with any automatic alarm signal or manually entered request, the vehicle position can be accurately determined anywhere in the world using GPS positioning information (Global Positioning System). The invention provides for continuous monitoring of a large number of vehicles over a wide range of conditions and 9,999,999

US 5,432,495 discloses a sound-operated vehicle safety system in which a decommissioning device, such as an ignition killing switch, is optionally switched on either by a hand-held radio frequency transmitting unit or by satellite broadcasting of a paging system triggered by a telephone call. . Also, a vehicle motion detector is activated, which turns on the transmit monitor when the vehicle is then moved, allowing detection by means of a portable receive monitor that the vehicle owner has or is in police vehicles.

Although it is advantageous to remotely signal an alarm condition by a cellular network and GPS in addition to the usual ignition off of a vehicle, a D1-based expert has no reason to take into account the known prior art since it describes something other than the problem contained in the D1 and the present application.

Although the use of a commercial mobile phone system does not represent a significant part of the cost compared to the value of the guarded facility, it will in any case impose additional financial burden on the owner and if the alarm is not received at the control center serving this purpose, an additional mobile phone is required. Another practical shortcoming of the mobile phone can be considered that it cannot be used anytime, anywhere, partly for technical, partly for security and partly for social reasons, so that commands sent by the owner to the building via telecommunications equipment affecting the activity of the building circumstance released.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a method and system that does not require the installation of any alarm system that can be turned off almost exclusively by the owner or a person authorized by it and capable of providing monitoring without requiring another mobile phone to transmit signals and control commands via telecommunications links. far away, and even if it gets out of the area covered by the telecommunications system, it will still be able to automatically maintain the idle and off state caused by the alarm signal issued.

A further object is to enable the invention to provide efficient use of modern location finding devices useful for tracking and moving the vehicle while it is in motion when the vehicle engine is not running, for example when driven by another vehicle and to connect the device to the system of the invention.

Another objective is to allow the removal of an artificially induced breakdown (including starting blocking) of the vehicle only by a highly skilled technician only if he has information related to some vehicle identification data known only to the owner (or rightful user) or his representative.

The invention is based on the fact that a conventional alarm system can be disconnected at any time using its own means, but this interlock can be automatically reactivated unless prevented by a separate individual and specific code issued by a person authorized to do so and can be given by telecommunications resources (for example, using a mobile phone system), or the location of the object. Furthermore, it has been found that multi-level on / off operations of a system to protect a guarded object can be integrated with the control performed through telecommunications, also considering the suitability aspect. A much safer and faster connection can be achieved by transmitting data using SMS (Short Message Service). GSM System «· ··· ♦ •» »

900 allows location (location identification) of a given mobile phone and tracking its movement when it is hidden in a vehicle and connected to a location identification unit.

It has also been found that two remote control devices can be used to increase the security margin - for example to avoid code breakage - one of which is hidden in the building and re-activates the alarm system immediately after it has been turned off. Thus, effective shutdown is only possible with a message sent to a mobile phone hidden in the vehicle.

Furthermore, it has been found that a vehicle may be deemed to be a real fault that does not cause an immediate stop and which can be corrected by an experienced technician only if it knows the information stored in the computer database regarding the location of a specific fuse or other disconnecting device ) hidden in any case elsewhere.

It has also been found that the on / off can be carried out directly by the mobile phone even in peak telephone traffic, the shutdown, i.e. the opening of the vehicle can be transmitted by an acoustic transmitter producing DTMF sounds or acoustically by mobile phone, i.e. without GSM.

It has also been found that the task of transmitting property protection information can be given to dedicated communication devices of simpler design than a general purpose mobile phone, also operating in the mobile phone's frequency range, but with a simple configuration it can be made cheaper and easier to install. auxiliary elements necessary for its use is also smaller.

On the one hand, in order to accomplish the intended task, a method of remote supervision of a protected object without a built-in alarm system is proposed, comprising the step of introducing at least one faulty function into the object during

Remote control 15 is installed covertly, in different vehicles at different locations, special workshops installing the system keep records of it stored in the computer memory at the same time as the registration number of each vehicle.

In this case, the control means 14 comprises relays 141 to 145. The first relay 141 is connected to the engine starting circuit, to which the passenger compartment heating circuit is also connected. The second relay 142 is coupled to the engine override assembly and causes - by opening the concealed relay - for example in the electric fuel pump circuit - a truly looking defect that can only be repaired in the repair shop, the malfunction manifested by the vehicle jumping and then stopping; the relays are hidden in different vehicles at different locations that are stored in the computer's memory, the fault cannot be repaired in place. The third relay 143 is operatively connected to the air conditioning system. The fourth relay 144 is a switching device, while the fifth relay 145 is operatively coupled to a servomotor that drives an atomization type indicator.

In another embodiment, a purpose-oriented transceiver, such as a GSM Module M1 manufactured by Siemens Ltd. operating in the GSM 900 / DCS 1850 system, is used instead of the mobile phone 10.

4 is connected to a DTMF decoder 86 for transmitting digital data, a control circuit 87, and a voice recording device 88. The logic interconnection unit 8 comprises, in addition to the above, a low frequency amplifier 89 performing amplification of analog signals in a manner described later . The DTMF decoder 86 may be MT8870D by MITEL, a.s., and is coupled to the microcontroller 85 as a four-bit decoder. The control circuit 86 amplifies the control signals provided by the microcontroller 85 to be suitable for controlling the control means 14, i.e. relays 141-145 according to this example, and is provided by an ULN 2003 integrated circuit. The voice recording device 88 is an ISD 1016 chip from Information Storage Devices, working as a dictaphone, performing analog recording and playback of low-frequency signals fed to its input for 16 seconds per chip.

The low frequency amplifier 89 functions as a voltage amplifier and may be formed from any discrete portion or integrated circuit available on the market. Instructions regarding the sizing and wiring of these circuits can be found in the technical data or leaflets issued by the manufacturers or in the following technical literature: H.Lohninger: Angewandte Mikroelektronik, Vol. 2, IWT, DE; Class: Professionelle Schaltungstechnik, vol.3, Franzis publishing house, DE.

The signal output from the DTMF transmitter 17 is galvanically connected to the second input 892 of the low frequency amplifier 89. The DTMF transmitter is a commercially available device, but can be replaced by a DTMF code circuit of type MT 8880 from METEL with its associated keyboard. Analog input 861 of DTMF decoder 86 is also connected to output 893 of low frequency amplifier 89.

Also, the input / output terminal of the voice recording device is connected to the output 893 of the low-frequency amplifier 89 and to the analog low-frequency signal input of the mobile phone 10. This is not illustrated in detail in the drawing, since the determination of the mobile phone terminals depends on the type of product. The input / output terminal of the voice recording device 88 serves to transmit low frequency signals, while its input 882 is coupled to the output 852 of the microcontroller 85 and receives digital signals to select between recording and reproduction and to start / stop operation. Fig. 2 shows another mobile phone 18 at the communicated remote address, but for the reasons explained, this control device may not be suitable for wireless operation. Thus, as shown in the figure, the control mobile phone 18 is in communication with the logic interface unit 8 either through the GSM center 18 or via the microphone 12. This arrangement avoids possible problems with the mobile phone being switched off by the mobile phone in peak traffic. In such cases, simply by holding the handset 18 near the microphone 12, the microphone 12 acoustically receives the transmitted DTMF sounds and the correct code and disengages the alarm unit 2.

Figures 3, 4 and 5 show three further embodiments of the anti-tamper protection falling within the basic objectives of the invention, namely disabling the alarm unit 2 to be turned off. In a possible embodiment shown in Fig. 3, the activation output 853 of the microcontroller 85 is connected to the microcontroller activation input. 21 of the alarm unit 2. Although not shown in FIG

Fig. 4 shows a variant where, via the exciter 87 of the microcontroller 85, one of the control means 14, for example relay 141, is used to energize the alarm unit 2, the relay 141 is inserted into the supply line of the alarm unit 2. variation, where instead of the activation / deactivation signal of stage 3 of the RF receiver for microcontroller 21, the activation / deactivation signal is issued by microcontroller 85, in this case the fixed basic setting of alarm unit 2 emitting the alarm signal immediately after power input is used independently of any other setting.

The arrangement of FIG. 1 is illustrated in more detail in FIG. 5, wherein the other remote control 15 concealed in the vehicle is controlled preferably by the activation output 853 of the microcontroller 85.

In another possible embodiment, at least one of the sensors 5 is directly connected to the logic interface unit 8.

In operation, when leaving the vehicle, the alarm unit 2 is switched on by the remote control 4 forming part of the alarm system installed concealed in the vehicle, at the same time activating the control means 14, thereby ensuring unmanageability or at least malfunctioning of the guarded object (vehicle).

In the event of a normal, normal course of events, when the owner returns to the vehicle, he has two options to deactivate the protective status:

One possibility is to deactivate the alarm unit 2 in the customary manner with its own remote control 4, then enter the vehicle within the set time controlled by the microcontroller 85 of the logic interconnection unit 8 and enter the individual and specific code to deactivate the control means 14 and.

Said code may be input into the microphone 12 by a keypad coupled to the low frequency amplifier 89 of the logic interface unit 8 by a DTMF transmitter, or, if the keypad is not used, by a DTMF acoustic device, or a suitable mobile phone 18 of control type (e.g. NOKIA 2110). ), while entering the code without radio frequency connection, a mobile telephone 18 is used to enter the code into the microphone 12.

Another, more elegant and convenient, but more costly option is to call the mobile phone 10 hidden in the vehicle and form part of the proposed system by the controlling mobile phone 18 and enter the DTMF code after the connection has been established, instead of using the remote control 4 to deactivate the alarm unit 2 and separately enter the trip code. In both this case and the previously described case, the DTMF code embedded in the DTMF decoder 86 is converted to a four-bit signal and input to the microcontroller 85 input 854. The program stored in the microcontroller 85 is checked for identity with the preset code and relays 141 to 145 of control means 14 are disconnected by output 855 of microcontroller 85 by means of driver 87. In an abnormal, ie alarm case, the acoustic and / or optical signaling means 6 of the alarm unit 2 is activated with simultaneous switching on of the connected logic interface unit 8 at least once before leaving the vehicle, a call number is dialed into the memory of the mobile phone 10, for example as follows: the acoustic and / or optical means 6 is activated by the user and thus, according to the foregoing, is mobile phone 10 put into operation. Now an alarm message is entered (for example, INSERT) and the call number is dialed, then by switching off the acoustic and / or optical means 6_b the mobile phone 10 will be automatically disconnected, but will retain the call number indefinitely. In the event of an alarm, the mobile phone turns on, then

9 automatically dials the entered call number and forwards the message. If the called number is busy, or in the case of a missed call for some other reason, the call is automatically repeated at set intervals (say, every minute) set on the microcontroller scale 85 until the phone owner 10 these calls do not stop manually.

Further, by means of a location adapter (for example, a GPS transmitter) connected to the communication connector 851, the position of the vehicle can be quickly and accurately detected, even if it was driven without starting the vehicle engine by lifting the crane onto the transport vehicle used by the thieves.

Other alternative uses of the system according to the invention are also possible. If a fixed telephone (connected to a digital telephone exchange) with DTMF option is available, or if the owner of the guarded object has a second GSM 900 (or DCS 1800) mobile phone 18, they can be added to the hidden mobile phone 10 other DTMF codes. If an alarm message is sent by the hidden mobile phone 10, the owner of the second mobile phone can temporarily turn off the alarm call. Then, after a preset time, for example after 5 minutes, the telecommunications connection can be re-established by sending additional DTMF codes also stored in the mobile phone 18. It may decide (if the mobile phone alarm 10 has disappeared in the meantime) if the alarm call was caused by accident intervention (transmitted by one of the signal transmitters in the building) or whether the alarm on the mobile phone 18 persists, thereby confirming the unauthorized intervention.

This avoids unnecessary visits to a remote guarded facility. Alternatively, the system may be controlled by DTMF codes such that the outputted decoded signals carry control information for the engine start circuit. Or, the owner can use this information to turn on the air conditioning system or sprinkler

However, by means of a series of DTMF information, the owner can disable the alarm unit 2 of his vehicle, since the second remote control 15 concealed in the vehicle will re-enable the alarm system if previously switched off by the first remote control 4. Namely, the opening pulse is also transmitted to the remote control button 15 hidden in the vehicle, thus preventing intrusion into the vehicle by instantly re-switching the alarm system. In this way, finding code can be avoided, which is possible with many current systems. An effective deactivation signal can be transmitted by the owner only by means of his second mobile phone 18 to the mobile phone 10 hidden in the vehicle. The decoded signal opens the closed protective circuit of the alarm unit 2 and disconnects the mobile phone 10.

The advantages of the invention are considerable - including its practicality - as compared to the current prior art. Even in comparison with building security systems using state-of-the-art wired telephone networks, any unauthorized intrusion information system can be easily prevented by interruption of telephone lines or accidental line breakdowns, all of which is very important, especially in the case of security guard or banking control systems. institutions.

In the case of vehicles, the safety of the invention is increased by eliminating the possibility of putting the vehicle into operation, so that it can only be stolen by loading onto another vehicle. But in this case, by connecting a commercially available adapter to the controller, the thieves' path can be tracked. The special antenna arrangement of the designed mobile phone may reveal a way of protection, as the proposed system will become more and more known. Thus, it will be appropriate to use hidden plate antennas or hybrid antennas that look similar to conventional antennas to operate both the radio and the mobile phone.

In case of connecting the alarm system sensors 5 to the parts of the vehicle inevitably generating some kind of signals during the direct or indirect movement of the vehicle, for example to the chassis, to the crankcase, these sensors 5 will sense wheel or mechanical fuel pump rotation. the vehicle, or any engine start, the information will be sent to the alarm unit 2 and in the manner described to the owner or security organization performing the remote surveillance task.

In the foregoing, the invention is described in connection with the remote supervision of vehicles. But our design can be used not only for the protection and remote supervision of mobile objects, but also for real estate. In the following, the functional and other deviations associated with the arrangement of circuits and parts occurring in the case of remote supervision of buildings will be briefly described, with reference to the data relating to the remote guarding of vehicles.

Among the sensors 5 of the alarm system developed for building protection is a sensor 5 providing undisturbed connection to the alarm unit by means of a built-in permanent link and in case of interruption, overload, deliberate interruption of wiring, etc. In the buildings, control means 14 are installed to trigger interventions affecting the use of the building, such as interruption of the power supply, water, gas and heating of the building, or blocking the operation of automatic door, window, etc. locking devices. , informing the security center by wired or wireless communication links, also by moving pictures, of current on-site events, following activation of the alarm unit 2.

Of course, the same mobile phone system located in a secure area can be used to inform the owner by written or verbal messages by a terminal connected to the wired telecommunications network and the connection can also be established through the microphone-handset door system with the visitor calling from the door and the owner the visitor knew that the person called was not at home at the moment. The proposed system can be easily supplemented by the addition of several parts of the system installed by an expert, and the system is able to inform the security center of the damage caused by natural disasters immediately after their occurrence.

The anti-tamper protection of the system according to the invention and the use in remote building surveillance can be accomplished by connecting the switching means with a holding relay (not shown) to activate the remote alarm unit 2. The holding of the relay can be deactivated via a logic interface unit 8 18. The alarm unit 2 will be activated in the usual way using a switch.

By utilizing the internal intelligence of the designed system, automatic indication of tamper acts can be performed, such as disconnecting the power supply, destroying electronic components with high-voltage pulses, deliberately damaging the system, and short-circuiting. In such cases, the microcontroller 85 sends a short sabotage message to the owner via the mobile telephone apparatus 10 without the offender being able to interrupt the telephone connection, the movement of the offender being observed on the display of the monitoring device. The frequency connection of the mobile phone eliminates the possibility of interrupting any connection.

For example, the microphone 12 may receive a notification of the execution of its command signals issued in the DTMF mode. These command signals can be issued, for example, to turn on the heating boilers installed in the building after
