Definitions

  • the invention relates to a system for controlling the entrance into a lockable room, for example a car, a building and the like, comprising a first unit, which is mounted inside said room, and a second unit, which during operation remotely controls said first unit with a control signal for opening or closing said room, which control signal is changed by either one of said two units.
  • a control system of this type is inter alia known with (passenger) cars, whereby the first unit is mounted inside the car and the second unit is mounted in or on the car key, and for example in connection with the opening and closing of garage doors.
  • a drawback of this known control system is that with this system there is a possibility that unauthorized persons, who should not have entrance to the car in question, pick up the control signal which is being emitted by the second unit (for example a hand-held device/key) by means of a receiver, for example a scanner, and process said signal, for example by using a computer programme, after which they transmit said signal to the car with a transmitter, as a result of which the lock of the car is opened and an alarm that may be connected thereto is turned off.
  • the second unit for example a hand-held device/key
  • Another drawback is that this may lead to the car being stolen or the house in question being burglarized.
  • the object of the invention is to provide a control system which does not have the above drawbacks.
  • a control system according to the invention is characterized in that the one unit transmits a proposal to change said control signal to the other unit and changes said control signal after receiving an OK-signal from said other unit.
  • the invention is based on the principle that since the control signal is not changed until an OK-signal has been received, the one unit (in/on the key) is prevented from changing the code (the control signal) without the other unit (car, building) receiving said change signal. This might lead to the control signal getting outside the (frequency) range of the (receiving) unit after a number of changes.
  • control system according to the invention allows much more freedom to change the control system than has been possible with the known control systems.
  • control system includes a processing unit, which is controlled by said first unit.
  • the Figure shows a schematic embodiment of a control system according to the invention.
  • the Figure shows a schematic embodiment of a control system 1 according to the invention, which is mounted inside a car.
  • the control system includes a first unit 5, which is mounted in a lockable room 3 (for example a car or a house or the like).
  • Said first unit is controlled by a second unit 7, which is located outside said room, for example in a key/hand-held device.
  • Said second unit emits a control signal S to the first signal for opening or closing the room 3.
  • the first unit After receiving the control signal S, the first unit will emit a signal to a processing unit 9.
  • the signal is converted by said processing unit into signals to a central door locking unit 11, an alarm unit 11 and a starter interrupter 15.
  • the central door locking unit 11 will emit a close or open signal for all doors upon receipt of a signal from the processing unit 9.
  • the alarm unit 13 may also be controlled by a signal from the processing unit for activating or deactivating the alarm, as the case may be.
  • the processing unit 9 may also control a starter interrupter 15 so as to disable or enable the starting of the car.
  • the unit 7 may for example be mounted in or on a car key, if the lockable room is a car.
  • the above-described system makes it possible to control the door locking system as well as the alarm and the like with one control signal S.
  • the second unit 7 periodically emits a signal V to the first unit 5 to change the control signal S. If the first unit 5 agrees to the proposed change, said first unit 5 will in turn emit a signal A to the second unit 7, whereupon the control signal S is changed.
  • the second unit 7 is prevented from changing the control system without the first unit 5 being aware of this, as is the case with the systems known so far, for example if the key containing the second unit is operated outside the range of reception of the first unit 5, whereby the control system is periodically changed, with the risk that the frequency of the control signal will get outside the frequency band of the first unit after some time.
  • the control system according to the invention enables the control signal S of the second unit 7 to be changed in various random ways (after an OK-signal from the first unit), without the control signal S having to remain within a certain frequency band, for example.
  • the change of the control signal may be any random change, and it is not limited to a certain frequency band or to a limited number of changes, as is the case with the systems known so far.
  • Additional security may be provided by transmitting a number (for example n) along with the proposal to change and also providing the OK signal A with said number n.
  • the next change number will then be n + 1, etc.
  • the proposed change may for example be a random number, which is added to the frequency of the control signal.
  • said unit may repeat the proposal (for example with the same change number).
