Abstract
A vehicle security device for remote control of electrically operable parts of a vehicle comprises a radio frequency receiver (7) adapted to receive a radiated radio frequency signal via a distributed communications network such as a pager communications or cellular telephone network in response to an actuation signal initiated by a user. The radio frequency receiver (7) provides an output signal in response to receipt of the radiated radio frequency signal to effect remote control of an electrical relay unit (14) to immobilise the vehicle. The device can alternatively be used in portable electrical equipment, e.g. a computer, to render it inoperative.
Description
DEVICE FOR REMOTE CONTROL OF ELECTRICAL APPARATUS
The present invention relates to a device for remote control of electrical apparatus and relates particularly, but not exclusively, to a device for remote control of security features in a vehicle.
In view of the high level of theft of and from motor vehicles, a number of security features for motor vehicles are currently available, including vehicle alarms or immobilisers which are automatically activated when tampering with a vehicle is detected. Such existing arrangements have the drawback that criminals are often able to disable such security features with the result that when theft is detected, the vehicle has often been hidden or driven away.
For the convenience of vehicle users, a number of electrically operated vehicle features are available such as central locking or alarm systems, and which are operable by remote control. However, such arrangements have the drawback that remote operation occurs by means of a transmitter held by the vehicle user which emits a signal to a detector located in the vehicle. This results in the equipment only being operable over a relatively short range.
Preferred embodiments of the present invention seek to overcome the above disadvantages of the prior art.
According to an aspect of the present invention there is provided a device for remote control of electrical apparatus, the device comprising a radio frequency receiver mounted in use to the electrical apparatus and adapted to receive a radiated radio frequency signal via a distributed communications network in response to an actuation signal initiated by a user of the device, wherein the radio frequency receiver in use provides an electrical signal in response to receipt of the radiated radio frequency signal to effect the remote control of the electrical apparatus.
By providing a device which can be operated over a distributed communications network, for example a paging or cellular telephone network interfacing with the public telephone system, this has the advantage that operation of the device by the user is still possible, even if the device is outside of the range of operation of remote control transmitters of the prior art.
In a preferred embodiment, the distributed communications network is a pager communications network.
By providing a device which can receive a radio frequency signal via a pager network, this has the advantage that the likelihood of the electrical apparatus being removed without authorisation beyond the range of operation of the device is minimised, since in the United Kingdom and in most other countries, most, if not all, of the country is covered by a pager network interfacing with the public telephone system.
Alternatively, the distributed communications network may be a cellular telephone network. This also provides the advantage of widespread accessibility of the device via the public telephone system.
The device may be adapted for installation in a vehicle.
Alternatively, the device may be adapted for installation in portable electrical equipment. For example, the device may be adapted for installation in apparatus such as a computer, video recorder, audio equipment or the like for rendering the apparatus inoperative in response to actuation of the device.
The device preferably further comprises electrical relay means connected in use to the electrical apparatus for effecting remote control thereof.
The apparatus preferably further comprises electrical relay drive means for actuating the electrical relay means.
The relay drive means may comprise a thyristor.
In a preferred embodiment, the device is adapted to effect remote control of the electrical apparatus in response to interruption of electrical power supply to the device.
This has the advantage that unauthorised removal of the device from the electrical apparatus can actuate security features such as alarm devices, vehicle immobilisers, or the like.
The device may be adapted to receive a plurality of radiated radio frequency signals, each of which effects a separate remote control function of electrical apparatus.
According to another aspect of the invention, there is provided a device for remote control of a vehicle, comprising a device as defined above connected in use to electrical apparatus comprising one or more electrically operable parts of the vehicle.
This provides the advantage that electrical systems of the vehicle are operable by a vehicle user even if the vehicle user is outside of the range of conventional remote control signalling devices.
For example, security features such as alarms and/or hazard warning lights and/or central locking and/or an immobiliser of a vehicle could be actuated on detection of vehicle theft.
Alternatively, a vehicle engine could be remotely switched on, for example to operate a vehicle heater to warm a vehicle prior to use.
In a preferred embodiment, the device is connected in use to a fuel pump and/or an ignition coil and/or hazard warning lights and/or a siren and/or central locking of a vehicle.
The device may further comprise delay means for preventing remote control of the vehicle until the vehicle is stationary.
This enhances the safety of the system by preventing disablement of a vehicle (and consequent loss of control thereof) while the vehicle is moving.
In a preferred embodiment, the delay means comprises logic means for preventing remote control of the electrical apparatus in response to detection of an ignition sense signal of the vehicle.
A preferred embodiment of the invention will now be described, by way of example only and not in any limitative sense, with reference to the accompanying drawing, in which:
Figure 1 is a schematic diagram of a vehicle security device embodying an aspect of the present invention.
Referring to Figure 1, a vehicle security device 1 for mounting within the body of a vehicle (not shown) has a housing (not shown) of suitable material such as ABS plastics or any other suitable material transparent to radio frequency radiation.
The security device 1 includes a power supply regulator 2 for receiving an unregulated 12 volt DC supply from a vehicle battery (not shown) via line 3, and providing a 12 volt DC regulated output on line 4, a 5 volt DC regulator output along line 5, and a 1.5 volt DC regulated output along line 6, the function of which outputs will be described below.
A radio frequency receiver 7 is powered by the 1.5 volt DC supply on line 6, and is arranged to receive a radio frequency radiated signal via an antenna (not shown) and provide a trigger pulse on output lead 8 in response to receipt of the RF signal.
The RF receiver 7 may be any suitable device, such as a commercially available numeric pager, for example a 724M2 type pager manufactured by Motorola, which is designed to receive an
RF paging signal from a transmitter (not shown) in response to a paging signal on the public telephone system.
A logic unit 9, such as a flip-flop, is powered by the 5 volt DC supply along line 5, and provides a latched input to an inverter 10 in response to receipt of the trigger pulse from the
RF receiver 7 along lead 8. The output of inverter 10 is provided to an input of an OR-gate 11, the other input 12 of which is connected to the ignition circuit (not shown) of the vehicle to detect whether the engine of the vehicle is switched on.
The output of OR-gate 11 is supplied to an input terminal of a relay drive 13 such as a 0.2 volt GaAs thyristor, which is powered by the 12 volt DC regulated supply along line 4. The output of the relay drive 13 is supplied to an electrical relay unit 14, such as a 20 amp 4-pole relay, also receiving electrical power from the 12 volt DC regulated supply. The relay drive 13 is arranged to supply electrical power to the relay unit 14 under normal operating conditions, and to interrupt the supply of electrical power to the relay unit 14 when the receiver 7 receives a suitable RF signal.
The relay unit 14 has a plurality of relay elements 15 (of which 4 are shown in the figure, but any suitable number may be used), each relay element being connected to one of the fuel pump, the ignition coil, the hazard warning lights and the central locking of the vehicle. A 12 volt output is also provided along line 16 to a vehicle siren (not shown) which can be actuated in response to a change of the logic level of the output signal of the relay drive 13.
The operation of the device 1 shown in Figure 1 will now be described. When the vehicle is operating normally, no RF signal is received by receiver 7, which in turn provides no trigger pulse. As a result, no latched output is provided by logic unit 9, as a result of which the input provided to the relay drive 13 does not change. Electrical power is therefore supplied to the relay unit 14 such that the fuel pump and ignition coil circuits are enabled, while the central locking, hazard warning lights and siren circuits are disabled.
If tampering with or theft of the vehicle is detected by the authorised vehicle user, the unique paging number of receiver 7 is dialled on the public telephone system, in response to which an RF radiated signal is sent to the receiver 7 from the nearest paging transmitter (not shown). The receiver 7 will be within range of such a transmitter in most, if not all, of most countries having the necessary infrastructure for pager communications networks.
On receipt of the RF signal via the receiver 7, an output pulse is provided along line 8 to the logic unit 9, in response to which the input of inverter 10 becomes HIGH, and the corresponding input of OR-gate 11 becomes LOW. If the vehicle is in motion, however, the signal along line 12 is HIGH and the output of OR-gate 11 does not change from HIGH, its value under normal operating conditions.
When the vehicle becomes stationary and the engine is switched off, the ignition sense signal along line 12 becomes
LOW, at which point both inputs of OR-gate 11 are LOW, and the output of OR-gate 11 becomes LOW, and the input to relay drive 13 changes. As a result, electrical power to the relay unit 14 is interrupted and two of relay elements 15 are opened to disable the fuel pump and ignition coil circuits. At the same time, two of the relay elements 15 are closed to actuate the central locking and the hazard warning lights of the vehicle, and an output is also provided along line 16 to actuate a vehicle alarm siren (not shown).
Because the security device 1 is actuated by means of interruption of electrical power to the relay unit 14, if the device 1 is separate from the relay unit 14, unauthorised removal of the device 1 from the vehicle also interrupts the electrical power supply to relay unit 14 to actuate the security features with the same results as receipt of an RF signal by receiver 7.
It will be appreciated by persons skilled in the art that the above embodiment has been described by way of example only, and not in any limitative sense, and that various alterations and modification are possible without departure from the scope of the invention as defined by the appended claims.
In particular, by provisions of a suitable gating arrangement in the device, the skilled person will appreciate that the device can be arranged to produce a plurality of output signals 8 from the receiver 7, each of which effects a separate remote operation. The plurality of outputs could be produced sequentially, and the order in which the outputs produced could be adjusted. Also, further features known to persons skilled in the art, such as automatic dialling apparatus or vehicle tracking apparatus, may be included.
