Description

RADIO LOCATION DETERMINATION .AND NOTIFICATION
FIELD OF INVENTION The invention comprises a radio location unit for location and reporting information.
A problem frequently arising is that of locating mobile equipment. This problem applies to tracking and monitoring fleet vehicles as well as to individual equipment or goods. One example is monitoring the position of a cargo container in transit. The container may be carried by several different means of transportation and be required to wait in several different distribution centres. This invention addresses the problem of notifying the owner or agent of its location. Another example is that of equipment or goods that are subject to theft or otherwise becoming lost. This invention allows notification of the location of the items without knowledge of the intended or anticipated location.
BACKGROUND ART
Location System Terπunals
Known location and navigation systems such as the Global Positioning
System i.e. GPS, LORAN etc provide mobile terminals with the ability to determine their location.
These systems vary greatly from small handheld units to large installations of equipment. Systems such as GPS use satellite base stations emitting carefully designed
- 1 - and timed signals which allow a compatible receiver to calculate its own position. Other systems use base stations located on land at known locations on the earth. Regardless of the system the operator of one of these location system terminals is presented with location and/or navigation information appropriate to the location of the terminal that they are operating.
Communication System Terminals
Radio communications networks now provide widespread coverage. Cellular phones, for example, allow the user to move freely over large areas, without any
obvious disruption of service from place to place. These communications networks therefore provide the facilities for a compatible terminal device to communicate over a large area without prior knowledge of the movements to be undertaken. The use of modems is now widespread. Modems allow digital information to be communicated over virtually any communications link. Examples of communications links of this sort include telephone calls, cell phone calls, mobile telephone calls, fibre optic cables, microwave radio links. Many communications links explicitly provide facilities for digital information communication. Examples of this type of link include advanced digital cell phones, GSM and DAMPS.
GENERAL DESCRIPTION OF INVENTION
In broad terms the invention comprises a radio location unit incorporating a location system terminal pan which determines location information from global or regional navigation or location system, and a communications system terminal part arranged to report the location of the unit from the unit over a communications network.
The location system terminal determines the physical location of the radio location unit and provides location information to the communications terminal part in machine compatible form. For example the location terminal may comprise a compact GPS terminal with RS232-C output capacity. Other location terminal technologies besides GPS may be used. Also alternative software and/or hardware interfaces may be employed including I2C, parallel memory and IO bus mappings, and full communication protocol implementations.
The communications terminal part communicates the location information transferred from the location system terminal, for example to the owner or agent. For example the communications terminal part may comprise a cellular telephone terminal which reports the location information over a cellular telephone network. Such a cellular telephone based communications terminal may report the location information through any other communications network however, such as plain old telephone systems (POTS), fibre optic networks, microwave systems. These network systems may be proprietary or public systems provided by a network provider. Examples of systems envisaged as "public" include: Telecom Cellular, AMPS, DAMPS, GSM, FM or AM dispatch systems. The radio location unit of the invention may be designed to be handheld, vehicle mounted, or housed in any convenient way attached to the item or items to be located or tracked.
The communicated information includes location information. The location information from the location terminal part may be in a raw form from which location may be derived, or in a fully processed form. The location information may be coded in any desired format. For example the location information may be raw signals derived from the location system. These may be digitally coded and transmitted unprocessed by the radio location unit of the invention. Alternatively the radio location unit may process the initial location data and transmit the processed location information to a particular communications protocol and/or data structure. The location information may be optionally processed into a human recognisable form such as for example synthesised or sampled speech. The location information may contain the latitude and longitude of the radio location unit or any other information which allows location to be derived. The information may provide location on a global, regional or localised scale. The information may be coded or embodied in a packet or stream structure or any other communications protocol or format. Similarly the interface may transform the information and/or its format or representation before communication to the owner or agent.
The location system part which derives its location from a compatible location or navigation system such as GPS may operate continuously or only upon activation by polling for example. The location information from this section may also be available to the communications terminal part for reporting either continuously or also only upon request or activation of the radio location unit.
The interface section reformats, reframes, translates, interprets, modulates demodulates or otherwise converts the format and representation of the location information into a form compatible with transmission to the communications terminal. The interface section may perform a control role to initiate activity, as further described below.
The preferred form of the invention shown in the drawings comprises a small GPS terminal connected via an interface to a data-compatible cellular phone. The GPS terminal continuously monitors its location and communicates or makes the current location information available to the cellular phone terminal via a data interface. At predetermined timed intervals the interface section initiates latches the location information and initiates a cellular phone call to report the location information to an owner or agent for example. The interface section transfers the information to the cellular phone terminal which is then reported over the medium of the cellular phone call. Upon completion of the data transmission the cellular phone is instructed to hang up and the cycle stops until the interface initiates the next.
In an alternative arrangement the radio location unit may be arranged to receive a security input which initiates location reporting upon receipt of such a security alarm. Examples include forced entry detection in vehicle and storage containers which would initiate sending of a radio alarm signal including location information indicating the location of the vehicle or storage container at the time of the security alarm actuation and motion detectors which also indication location at the time they are activated.
Alternatively, again the radio location unit and particularly the interface part may be programmable to allow a predetermined sequence or times of initiations to
take place. A location and notification sequence may be initiated by receiving and answering a poll from the owner or agent. In an implementation using a cellular phone compatible communications terminal this poll may be as simple as a call to the terminals associated number. A location information report from the radio location unit initiated by the device itself, by the owner or agent, or by some other event, may transfer central information to the device from a remote point. For example the frequency of timed initiations could be programmed from a remote point.
The radio location unit of the invention may be arranged to communicate its location information to multiple sites. The device may initiate communication to more than one site by using a compatible broadcast network that allows one to many dispatch type calls. Alternatively the device may maintain a list of sites to notify. A cellular phone compatible communication terminal may maintain a list of numbers to call and notify. An implementation capable of answering a poll may allow communication of the information to any caller. This communication sequence may optionally include an identification phase to verify a right to receive the information before it is transferred. DESCRIPTION OF DRAWING
The invention will be further described with reference to the accompanying drawing by way of example which illustrates the system of the invention.
DESCRIPTION OF PREFERRED FORM
Referring to Fig. 1 the preferred form unit comprises a GPS receiver and a cellular phone communications terminal. The GPS receiver terminal determines the location of the unit and transfers location bearing information either as raw data or processed information e.g. latitude and longitude, to the communications terminal. The communications terminal reports the location bearing information to the receiver such as an owner or agent via an existing communications network through typically a base station. Reporting of location information may be initiated by interrogation of the unit over the communications network.
Fig. 1 illustrates, by way of example, a configuration of the invention using the GPS positioning system and cellular phone networks. A possible sequence for events for an interrogation system is:
* The owner, or agent, initiates a call over the PSTN and cellular phone network to the device.
* The device answers the call.
* After establishing the connection, the device transfers location bearing information back to the owner or agent. This information could be in the form of raw data from the positioning system, partially processed data from which location is derivable, or fully processed data providing location directly.
The figure also shows optional self activation. In this mode, sensors at the device initiate the report. This could consist of security sensors to detect movement, sound, electrical supply changes etc. The sequence is then initiated at the device:
* The sensors recognise a condition requiring notification.
* The device initiates a call over the cellular phone and the PSTN networks to the owner or agent.
* Personnel or equipment at the destination answers the call.
* After establishing the connection, the device transfers location bearing information back to the owner or agent. This information could be in the form of raw data from the positioning system, partially processed data from which location is derivable, or fully processed data providing location directly.
* The device may optionally maintain the connection or disconnect.
The foregoing describes the invention and alterations and modifications as will be obvious to those skilled in the art are intended to be incorporated within the scope hereof as defined in the accompanying claims.
