Definitions
- the present invention relates to a wireless object locating system comprising a radio alarm apparatus for attaching to an object, which radio alarm apparatus comprises a security arrangement for sensing an alarm condition of the object, and an alarm transmitter for transmitting an alarm message to a central alarm station, whereby the security arrangement is arranged for producing an alarm signal when the alarm condition is sensed.
- a wireless object locating system is used for identifying the position of valuable movable objects, such as a vehicles or the like, when stolen, or for identifying other movable objects, when an alarm condition occurs, such as with elder or disabled people, or on assault, on burglary, on accident, or the like.
- the present invention further relates to a central station and to a radio alarm apparatus for use in such a system.
- the known system is a combined cellular mobile radio and global positioning system.
- the known system comprises mobile radio terminals having a mobile radio transceiver for communicating with mobile radio base stations which are coupled to a switched telephony network that can be a public network.
- the mobile radio terminal which is comprised in a vehicle for instance, comprises a global positioning receiver, like a so-called Navstar receiver, periodically determining a position of the vehicle at which the mobile radio terminal is attached or in which the mobile radio terminal is located.
- the mobile radio terminal further comprises an anti-theft-security arrangement that produces an alarm signal, when armed and when an alarm condition occurs such as an attempt by an unauthorised person to steal the vehicle.
- the security arrangement is armed by an authorised user of the vehicle, when leaving the vehicle.
- a disarm receiver such as an infrared or very short range radio receiver is provided which can be operated by an authorised user of the vehicle only, by entering a code on a device which is coupled to the disarm transceiver, either wireless or by wire.
- a currently determined position of the vehicle is sent to a central despatch office in an alarm message by the mobile radio transceiver via a mobile radio network and the switched telephone network to which the central despatch office is coupled.
- the vehicle can be continuously located.
- the central office evaluates the alarm message, and an appropriate action can be taken.
- the location of the vehicle can be accurately determined an followed with such a system, when the vehicle is intruded and/or stolen, the known system is complicated because of the additionally required GPS (Global Positioning System) parts. Such additional GPS parts also increase system costs. Furthermore, when the mobile radio terminal transmits alarm messages when the vehicle is stolen, the mobile radio's subscriber is still has to pay for call charges.
- GPS Global Positioning System
- a radio automatic alarm transfer system for detecting an abnormal condition of an automobile.
- this system which is a multi channel access mobile radio system
- an exclusive upstream and downstream channel are applied to and from a base station of the mobile radio system for transferring alarm messages from the automobile to the base station, and for alerting an owner of the automobile having a mobile radio handset with an alarm sound actuator which is actuated by means of an alarm message received via the base station, when an alarm condition occurs in the automobile, respectively.
- No central alarm evaluating and object positioning station is disclosed.
- a traffic emergency system is disclosed for centrally evaluating emergency calls, such as calls reporting accidents with or without personal injuries at an accident's location, from relay stations covering a geographical area. The location of the accident is determined on by direction finding based on data from a number of relay station, intersecting directions giving the location of the accident. Neighbouring relay stations placed at a distance of 10 kilometres approximately, with respect to each other.
- the wireless object locating system is characterised in that the alarm message is comprised in a wireless telephony emergency call message, and that the alarm transmitters are wireless telephony transmitters 3 which are arranged to transmit the emergency call message to the central alarm station via a plurality of base stations which are comprised in the system, whereby the base stations are coupled to the central station via a switched telephony network, and the base stations cover a wide area, and whereby the central station is arranged to determine a location of the object from a location of a base station receiving the emergency call message.
- the alarm transmitters are wireless telephony transmitters 3 which are arranged to transmit the emergency call message to the central alarm station via a plurality of base stations which are comprised in the system, whereby the base stations are coupled to the central station via a switched telephony network, and the base stations cover a wide area, and whereby the central station is arranged to determine a location of the object from a location of a base station receiving the emergency call message.
- the present invention is based upon the insight that it usually is not necessary to follow a vehicle with very great accuracy, when stolen, and further on the insight that, when an existing mobile or cordless radio system is available covering a large area with base station, the resolution of placement of base stations is such a system can be applied for locating purposes, when such a resolution is sufficiently small. It was also realized that in wireless telephony systems, emergency calls might by-pass a normal call validation applied for non-emergency calls.
- the alarm message comprises an object identifier and/or a base station identifier.
- the central alarm station can determine the location of the object when the security arrangement is still attached to it, and the base station via which the message was submitted, and thus, with the resolution with which the base stations are scattered over the coverage area of the system, the location of the object.
- the base stations form a micro-cellular network which is a cordless telephony network according to the so-called ETSI (European Telecommunications Standards Institute) DECT-Standard (Digital European Cordless Telecommunications Standard).
- ETSI European Telecommunications Standards Institute
- DECT-Standard Digital European Cordless Telecommunications Standard
- pr ETS 300 175-9, March, 1992, p. 25, par.4.1.48 and p. 40, par. 5.2.48 an emergency service access request is specified.
- the Standard specifies that the base station or cordless telephony fixed part must be able to distinguish between emergency calls and non-emergency calls to ensure by-passing of the normal call validation and establishment mechanisms if desired.
