Definitions

  • the present invention relates to security systems. More particularly the present invention relates to security systems which operate to detect stolen items electrical equipment.
  • Electrical goods are a common target for thieves and burglars. This is because such electrical goods are comparatively expensive items but more especially it is because of a lack of clearly distinguishing features of such goods which allows them to be resold or passed on by the burglars to unsuspecting buyers. If however the location of such goods could be monitored and tracked, stolen electrical goods could be rapidly recovered providing an inherent deterrent to thieves and burglars from stealing the goods.
  • a security system for locating items of electrical equipment, said security system comprising security identification units and a controller unit, said security identification units being located within said items of electrical equipment and arranged in use to communicate identification data with said controller unit via an electrical power distribution network to which said items electrical equipment are connected, thereby providing an indication of a presence or an absence of at least one of the items of electrical equipment.
  • the identification data may represent serial numbers which serve to identify the items of electrical equipment in which a security identification unit is embodied.
  • the security system may further comprise addressing units connected to the electrical power distribution network at strategic points, which addressing units operate to generate address data communicated via said electrical power distribution circuit to said controller unit.
  • the whereabouts of the item of electrical equipment may be determined from the identification number in combination with the address data representative of the point in the electrical power distribution circuit to which the item of electrical apparatus is connected.
  • the addressing units may be located within local sub-stations forming part of said electrical power distribution network.
  • the addressing units may be embodied within electricity meters associated with a domestic premises connected to said electric power distribution network.
  • the controller unit may operate to interrogate said identification units, in response to which interrogation, said identification units may transmit identification data representative of each of the identification units so interrogated.
  • the interrogation by the controller unit may comprise transmitting to the identification units via the electrical power distribution network identification data representative of items of electrical equipment known to have been stolen.
  • a security system for locating items of electrical equipment comprising security identification units embodied within the items of electrical equipment, and household controller units coupled to electricity circuits associated with premises where said items of electrical equipment may be operated, which household controller units have a data store and operate to store data therein appertaining to a list of identification data representative of serial numbers of items of electrical equipment for use at the premises, thereby providing in combination with said security identification units a register of items of electrical equipment to be used at a premises.
  • the identification units may operate to communicate identification data with the household controllers, which household controllers may further operate to compare the identification data communicated thereto by the identification units with the list of identification data registered for use at the premises. This may serve to establish whether any electrical equipment connected to the electrical circuits do not correspond with those present in the data store.
  • the household controller may further operate in combination with the security identification units to affect a disconnection of the electrical apparatus from the electrical power distribution circuit when said electrical apparatus is not recognised by said household controller.
  • FIG. 1 shows a schematic block diagram representation of a security system for identifying the location of items of electrical apparatus connected to a power distribution circuit.
  • houses 1 are shown to be connected to an electrical power distribution circuit 2 via a local sub-station 3. Electricity is conveyed from the local sub-station 3 to the houses 1 via conductors 4. Electricity is received in the houses 1 by main electricity unit 5.
  • the mains electricity unit 5 serve to meter electrical power consumed by the electrical power consumers represented by the houses 1.
  • the security identification units 12 periodically transmit via the electricity distribution network 2, identification numbers appertaining to a serial number associated with the electricity equipment 8, 9, 10, to the controller unit 18. This provides a means for registering the electrical equipment 8, 9, 10, for which security protection is desired with the controller unit 18 which provides a way of monitoring the presence of the electrical apparatus 8, 9, 10.
  • the household controller units 14, 15, 16, 17, are provided with a means of generating address data associated with each house 1, to which they are connected by conductors 4.
  • This address data may be representative of the postcode of the premises 1, where the electrical equipment is located.
  • other addressing units may serve to perform this function, and may be located elsewhere in the electrical power distribution network. In this case the address data would represent a part of the electrical distribution network associated with an addressing unit.
  • the security identification unit 12 When the identification number associated with the electrical equipment connected to the domestic electricity supply 6, and to the electrical power distribution network 2, is transmitted from the security identification unit 12, to the central controller 18, the household controller units 14, 15, 16, 17, (or addressing units) operate to append address data to the identification data.
  • This provides a means whereby electrical equipment may not only be monitored as to its presence at a predetermined location, but also to provide a means whereby the electrical equipment may be located wherever it is connected to the electricity distribution network.
  • the household controller units 14, 15, 16, 17, may be provided with a data store wherein there is stored a list of serial numbers appertaining to electrical equipment which is authorised for use at the premises associated with the houses 1. Furthermore the household controller units 14, 15, 16, 17, may be provided with a means for transmitting signalling information to the central controller unit 18, when any item of electrical equipment not authorised to be connected to the domestic circuit 6, associated with the houses 1, is connected to the electricity supply at that address.
  • the household controller units 14, 15, 16, 17, may be furthermore provided with a means for preventing operation of any electrical equipment not associated or recognised with either household controller units 14, 15, 16, 17, from the list of authorised serial numbers contained in the associated data store.
  • the central controller unit 18 may be located at the premises of a security company which may monitor incoming security or identification numbers and compare these numbers with known lists of registered items reported as being stolen. Thereafter such items may be located in accordance with the household unit indicated from the address data received with the identification data. Furthermore, when items of electrical equipment are known to have been stolen, the security company may arrange for the controller unit to interrogate the security identification units, by transmitting to the identification units via the electrical power distribution network identification data representative of items of electrical equipment known to have been stolen. In response to this interrogation, the identification units may transmit identification data representative of each of the identification units so interrogated. The location of the items of electrical equipment may thereafter be determined from the address data received with the identification data.
  • the location of items of electrical equipment may be determined by utilising information appertaining to the phase or the voltage of the electrical power supplied by the electrical power distribution network. Since the phase and the voltage of electrical power varies between different parts of the electrical power distribution network in a known or predictable way, this variation can be used to locate items of electrical equipment.
  • the controller unit may determine the location of the items of electrical equipment from the measured phase or peak voltage and information appertaining to the phase or voltage of the alternating current electrical power supplied by the electrical power distribution network at various parts of the electrical power distribution network.
  • both phase and voltage can be used to facilitate location of the electrical equipment.
