Definitions

  • the invention relates to a system to indicate burglary and to start preventive action and a set of units to put this method into practice.
  • the system is designed to protect both mobile and stationary objects and it allows for participation of emergency services such as traffic police patrols or guard services of car parks or any other guarded premises such as museums, warehouses or trading stations.
  • polish patent specification No. 152 186 describes an alarm system which uses a set of automotive door and/or front and rear hood opening switches, provided also with an inertial vibration pick-up with seismic mass, connected to the automatic vehicle supply source.
  • This is built on functors made in the CMOS technology and consists of the alarm signal switch-on block whose output is connected to the horn system of the vehicle to be protected and to the pass and/or head lights.
  • the embodiment of the above invention comprises an electronic ultrasonic sensor which releases the alarm, signal on the occurrence of disturbances inside the vehicle cabin of the mechanical wave generated by the ultrasonic transmitter.
  • Another Polish patent specification No.115335 describes a method and equipment to control automatically the area to be watched by the use of infra-red radiation. Transmitters emit sequential signals according to the preset program. These signals are converted into alarm signals in the central unit if there is no signal at least in one receiver. Then the central unit receives an alarm signal that the area to be watched is violated.
  • the Polish patent specification No. PL 285811 Al also describes a wireless alarm system comprising a transmitting block which emits a radio signal from the area to be watched in the form of short frequency-modulated carrier wave pulses.
  • the transmitter In the stand-by condition the transmitter emits a stand-by signal received by radio in the receiver. Owing to the alarm condition, the code of the signal is changed.
  • the known alarm systems which protect buildings and vehicles are characterized by a certain one-sidedness of functioning which is manifested by the fact that during forced entry or theft acoustic and/or light effects are activated or some elements such as, for instance, the ignition system are deactivated. If these effects are not detected, the perpetrator deactivates rapidly the alarm system and then his action goes on uninterruptedly.
  • the object of the invention is to develop such a system to indicate forced entry to a building or vehicle and its theft which would make it possible to locate and identify this object unnoticeably to the perpetrator and to start remote action from a stationary ormobile check point, suchas door ⁇ keeper's lodges, police radiocars or remote-controlled check points at cross-roads.
  • the method of signalling forced entry and starting preventive action is based on the fact that the protective device, undiscernibly installed in the object to be watched and set up by the owner to the stand-by condition by an individual identifying code, transmitted in the infra ⁇ red, in the case of forced entry transmits to the check point a forced entry FM radio signal.
  • This signal contains coded information with data making possible identification and location of the guarded object, it is transmitted intermittently, with pauses providing for the radio actuating signal to be received by the protective device receiver which releases the performance of deterring or intervening functions in this device.
  • the sending-receiving unit installed at the check points operates on the principle wherein a forced entry signal with coded data on the object where forced entry occurred is received from the protective unit and then decoded while the data identifying and locating the guarded object are recorded and displayed on a display or monitor. This results automatically or, through actuation by the check point personnel, in transmitting the actuating signal through the FM channel.
  • the forced entry signal with data identifying this guarded object will also be received by the owner and would make possible additional intervening or deterring action.
  • Transmitters and receivers of the FM signals of both pro ⁇ tective devices in guarded objects and sending-receiving units in check points as well as additional receivers located with owners of guarded objects operate over the same radio channel.
  • the set of forced entry indicating and emergency action units consists of the code trans ⁇ mitter, individual for a given guarded object and transmit- ted in the infra-red, installed undiscernibly and of the check point unit as well as an additional receiver controlled by the owner.
  • Both the guarded object protective unit and the check point unit are provided with transmitters and receivers of FM signals operating over one radio band.
  • the transmitter of data on the guarded object and receiver of the actuating signal in the protective unit of that object are automatically switched over to transmission/reception owing to their control inputs being connected to the signal from the switch-over block output, actuated by the signal from the alarm actuating block output and this output is also connected to * the alarm input of the data transmitter.
  • the alarm actuating block has the output from the code receiver connected to the stand-by input while its alarm input is connected to the output from the alarm release unit realizing the OR function of signals from the guarded object sensors.
  • the receiver of information from the check point unit comprises a FM signal receiver with coded data on the guarded object and code decoder of the guarded object and the output of the data receiver is connected to the input of the data display unit.
  • the actuating signal transmitter contains an actuating signal coder and FM signal transmitter and is activated manually by the check point operators or auto ⁇ matically, depending on the realization of the guarded object protective function.
  • the set of units to signal forced entry according to the invention also includes an additional receiver of the FM radio signal, containing the code decoder of the guarded object, transmitted by the data from the information transmitter of the protective device for this object and controlled by the owner of the guarded object.
  • the method to signal forced entry and to start emergency action as well as the set of units to perform this method ac ⁇ cording to the invention is a system for complex property protection. It solves the question of exposing the perpetrators of forced entry or property theft and starting such emergency actions as activating light and/or acoustic effects or special safeguarding effects, e.g. mechanical means, depending on realization of the actuating system function in the safeguarding unit of the guarded object.
  • By suitably selecting the transmission power rating in the guarded object protecting unit, in the check point units and sensitivities of receivers as well as by selecting a suitable coding system one can use one radio channel to operate the system over a large area, for any number of guarded objects.
  • Installation of an additional receiver at owner's premises enables the owner to receive a warning during forced entry into his object in spite of the fact that all transmitters and receivers operate in the same radio channel.
  • the embodiment according to the invention is used to prevent theft of motor vehicles the system operates without any territorial restrictions provided that the stationary check points or police radio cars are suitably arranged.
  • the stationary check points or police radio cars are suitably arranged.
  • a suitable lay ⁇ out of the data receivers on check points at cross-roads and major routes as well as transmitting these data to the central office may facilitate tracing the routes of stolen vehicles.
  • the invention is presented in the drawing as a block and functional diagram.
  • the set of units to protect the vehicle from the effects of forced entry or theft consists of an electronic key which is the code transmitter CT, kept by the vehicle Owner, the guarded object safeguarding unit GOS, undiscernibly installed in the vehicle and the check point unit CPU, in ⁇ stalled in fixed or mobile check points, for instance in the police radio car.
  • the code transmitter CT emits an infra-red signal IR comprising an identifying code individual for a givenvehicle, factory set with the replicability of 1:59047 so that the code transmitter of one vehicle wouldnot actuate another vehicle.
  • the IR signal is received by the code receiver CR of the safeguarding unit GOS where the signal is decoded and the GOS unit is switched to stand-by condition andthe signal appears at the stand-by input Sin of the alarm actuation block AAB.
  • the owner of the vehicle may at any time disconnect the stand-by function of the guarded object safeguarding unit GOS by reactivating the code transmitter CT.
  • the signal from the code receiver CR results in cancelling the stand-by condition at the stand-by input Sin of the alarm actuation block AAB
  • thealarm release unit ARU controls the alarm actuation block AAB at the alarm input AIn.
  • the output of that block is connected to the input of the switch-over block SB and to the alarm input AIn of the data transmitter DT.
  • the control inputs Cln of the data transmitter DT and actuating signal receiver AR are connected to the switch-over block output SB whose function is to switch over the data transmitter DT and actuating signal receiver AR to sending-receiving, in time with the internal clock.
  • the data transmitter DT codes the individual identifying code about a given vehicle and sends the FM signal with coded data which makes possible to identify and locate the vehicle in the check point unit CPU, in other words, it is the data about the type of vehicle, its colour and license number.
  • the actuating signal transmitted from the check point is received by the actuating signal receiver AR. This signal brings about preventive action in the actuating system AS, thus resulting in stopping the vehicle or tracing its movements.
  • the check point unit CPU comprises the data receiver DR which receives FM radio signals emitted by the data transmitters DT of particular guarded vehicles and decodes identifying signals about these vehicles. Decoded information is transferred to registers of the data display block DDB"and is displayed in such a way that its fragment describes the vehicle trademark, the next one - its colour and another one - its license number. These data are sufficient for the police patrol or personnel of the check point to identify the stolen vehicle and then this personnel starts to act, that is, the actuating signal transmitter AT starts to emit the actuating radio signal.
