Description
CA 022~2997 1998-11-06 Method and System for Monitoring the TranSportation and Positioning of Moving Objects.
Specification The invention relates to a method and system for monitoring the transportation and positioning of moving objects using a miniaturised high-frequency transmitter, preferably a fixed frequency transmitter, preferably in IC-card format.
From the unexamined German application DE 42 37 486 A1, a device is known for recognising the theft of a vehicle, especially a motor vehicle, a high frequency transmitter being provided which is secured on or in the motor vehicle. In the case where the vehicle is moved without authorisation i.e. by operation by a stranger the transmitter is activated whereupon a receiving system is in the position to receive signals emitted from the high frequency transmitter and to set off an alarm. The radius of the beam from the high frequency transmitter, which is located in the motor vehicle, is exceedingly small and locating the vehicle itself is not possible.
In the device for determining the position of a moving object according to DE 43 12 670 A1, a transmitter is CA 022~2997 1998-11-06 assigned to an object e.g. to a ship or to a land vehicle In order to arrange for position detection very exactly even in the near field region a differential-GBS-system~
i.e. satellite locating is fallen back on here. In fact, locating of an object can take place thus relatively exactly, however a transport route or transportation progression control and hence identification of the position of the objects is either not possible or only possible at considerable cost over a local or regional area. This is particularly true when a multiplicity of objects is provided with a corresponding monitoring device.
Likewise known are portable high frequency transmitters for keyless entry systems, especially for vehicles where the transmitter is designed in the format of a cheque card. Therefore, DE 36 27 194 A1 discloses a transmitter of the type of a transponder, which transfers high frequency energy in the near field in order to open e.g.
the door of a motor vehicle or to allow a vehicle to start.
According to US-PS 3,825,833, an electromagnetic transmitter is known which is arranged camouflaged in a key or similar. The transmitter is only activated in the case of danger, i.e. it is not connected until a corresponding manual handling of a current supply circuit CA 022~2997 1998-11-06 takes place. Then the short range of the transmitter can be increased quasi indirectly via transponder stations.
The transmitter described in the US Patent specification serves predominantly for sending out an emergency signal, the location itself being secondary. A similar emergency signal transmitter is portrayed in the unexamined German application document DE 38 19 057 A1.
Furthermore, it has already been proposed to provide vehicles, of higher price ranges especially, with a transmitter so that a satellite-supported bearing is possible in the case of a theft or other loss. Because of the fact that the equipment required for locating is relatively demanding and expensive, the use of systems of this type has up till now only been effective for the high value products mentioned. In the case of a cheap configuration of high frequency transmitters, which is entirely possible owing to a progressive miniaturisation and reasonably-priced electronic components, the basic problem resides in allocation if a multiplicity of objects is provided with transmitters of this type.
Proceeding from the aforementioned, the object of the invention is to offer a method and a system for monltoring the transportation and positioning of moving objects, also comprising persons or animals, by means of a miniaturised high frequency transmitter, said system allowing any CA 022~2997 1998-11-06 objects, persons or similar to be located in a particularly simple manner by falling back upon, as far as receivers are concerned, already available components or networks, as a consequence of which increased security is assured when transporting goods and also people. It is at the same time the object of the invention to improve the logistics of transportation by optimising the transport routes from data obtained while being able to make more precise predictions about the arrival time of goods and merchandise at their destination.
The solution to the object of the invention is achieved with a method according to the teaching according to Patent Claim 1 and also with a system with the features according to ~atent Claim 4, the dependent Claims comprising at least useful developments and further developments.
With the method according to the invention for monitoring the transportation and positioning of moving objects, e.g.
transport pallets, packets, containers, vehicles of all types, people, animals and also smaller articles such as luggage a miniaturised high frequency transmitter is attached to the pertinent object in as undetachable a manner as possible or being removable only by destruction.
It may be noted at this point that the attached, miniaturised high frequency transmitter is fixed to the CA 022~2997 1998-11-06 S
pertinent object in such a manner that said transmitter can be removed after use without destruction by authorised persons by means of a special tool. Separation of the high frequency transmitter by unauthorised persons is admittedly only possible in a destructive manner. By recording the last message of the transmitter, abnormalities can be detected. After clearing of the high frequency transmitter, a data telegram is sent at pre-set, if necessary programmable intervals of time, the data telegram defining the object unequivocally.
This definition is given by a special code which characterises for example the owner, the transportation goods, the carrier and similar. In addition, the data telegram contains information which permits verification with respect to the permissibility of a monitoring inquiry.
The sent data telegrams are picked up by receiver stations. These receiver stations are, in a particularly preferred manner, devices of GSM-, DECT- or a similar telecommunication network and/or devices of geostationary location satellites. ~referably, monitoring of transportation and positioning is carried out in the local and regional area using radio cells of a telecommunication network. In the continental monitoring area, on the other hand, geostationary location satellites are fallen back CA 022~2997 1998-11-06 upon. Especially when monitoring shipping routes, use of geostationary location satellites has proved to be especially advantageous.
The respective receiver data of both the radio cells of the telecommunication network and the geostationary location satellites proceed to a central computer, locating of the respective transmitter location and hence of the object being possible from the receiver data. Thus the transportation route of an object can be followed via several radio cells and retraced without needing to have special monitoring or receiving devices created.
Detection of the speed of the transport vehicle can result from monitoring of the transport route and the time and the possibility exists of determining excess driving periods or too long rest or break times and the pertinent location.
The recorded positioning or transport route data of the respective object are then transmitted upon inquiry and identification of the person being asked by pre-setting and checking of a code word which corresponds at le~st in part to the data telegram. This transmission to the authorised receiver, e.g. the carrier who is interested in where the sent merchandise is located can be realised via CA 022~2997 1998-11-06 regional and continental data communication ne~works e.g.
the Internet in a cheap manner.
The recording of data for a multiplicity of objects is achieved by and with the mentioned central computer which is used at the same time for calculating and billing of costs per inquiry.
In a development of the invention, the transport route and the transportation progression are reconstructed from the stored, recorded data, the speed of transportation and a provisional time of arrival at the destination being calculable from the available data.
In order to reduce the quantity of data being recorded in or with the central computer, storing only occurs when a change in position can be established on reception.
In the system according to the invention for monitoring transporting and positioning of moving objects a miniaturised fixed frequency transmitter, preferably in an IC card format or in a comparable handy format is fallen back upon. The fixed frequency transmitter had an identification marking which can be read manually or by a machine and transmits a data telegram after clearance at pre-set intervals, said telegram containing amongst other things the identification code.
CA 022~2997 1998-11-06 Furthermore, the system comprises a radio cell receiver network, preferably of a telecommunication operator and/or a satellite-supported location device for receiving data telegrams.
In the system there is used a central computer which is connected to the radio cell reception network and/or the satellite-supported location device and which records the received signals of the same identification code relative to the location in a corresponding data set so that upon authorised access to the central computer, the transport progression and the respective position of the object or objects can be accessed.
The fixed frequency transmitter used in the system and in an IC card format is designed as a so-called "tag" and comprises means for secure attachment to the object, as a result of which unauthorised removal can be largely excluded.
In a preferred embodiment of the high frequency transmitter used in the system this transmitter has a receiving part for remote-control clearance and/or switching from a sleep-mode to the transmission state so that a totally energy-saving operation and hence an adequate life-span of the independent transmission unit can be achieved.
CA 022~2997 1998-11-06 Because of the embodiment of the high frequency transmitter as a fixed frequency transmitter which only operates in the frequency area being used by normal telecommunication operators or satellite location systems, expensive tuning devices, i.e. electronically tuned oscillators or similar may be dispensed with so that the costs of producing the transmitter, especially with correspondingly large-scale manufacturing can be kept down. Because of the programmable type of intermittent operation of the transmitter energy consumption is small, as a consequence of which the useful life-span is increased in association with the remote-control clearance option.
On the basis of the fact that only authorised persons, who are seeking to make an inquiry, have access to the system for monitoring transportation and positioning, the demands of data protection and other entrepreneurial interests are taken into account.
As far as application is concerned, the central computer is operated or administered by a special server which releases the desired, stored position data or the transport progression after identifying the inquirer. In order to keep the amount of data to be handled to a manageable quantity information is not only stored solely CA 022~2997 1998-11-06 when a change in position of the objects has been established but also non-accessed data is deleted after a pre-set length of time when no changes in position have been established.
In one design of the invention, the inquirer, i.e. the client of the service system is informed about the transport progression and the present state or stopping location not only in co-ordinates but rather a graphical representation is achieved by using cartographic superimposition, the respective positions reached being provided with additional information such as the day and time.
The possibility exists, by means of a group identification code, of using the system according to the invention for larger carriers, car rentals or railway operators in order to put the latter in the position of being able to obtain an overview of the respective positions of the vehicles or similar quickly and comprehensively.
The invention is explained subsequently in greater detail with reference to an embodiment, given by way of example and with the additional help of a Figure.
Fig. 1 hereby shows a principal representation of the system for monitoring the transportation and positioning CA 022~2997 1998-11-06 of moving objects in the example of a container 1 which is located on a motor vehicle 3.
As shown, there is secured on the container 1, for example at one point where normally a piece of freight documentation is located, a fixed frequency transmitter 2 in the format of an IC card. The transmitter contains an identification marking either in plain text or in so-called BAR code.
This marking is registered by the carrier and is a component of the freight goods documentation. This means a corresponding marking is allocated to all freight, in the present case the container 1.
The data telegram emitted from the transmitter 2 after being given clearance contains an individual code which serves to identify the transmission signal and hence the container 1.
When the container 1 located on the motor vehicle 3 is moved locally or regionally on corresponding traffic routes the high frequency signals, which are transmitted at pre-set intervals of time, are picked up by the radio cell receiver antennae 4 of a GSM or DECT network operator and supplied to a processing station 5 which is a component of the available network. From the processing CA 022~2997 1998-11-06 station 5, the information can then be selected which corresponds to the radio cell transition when the motor vehicle 3 with the container 1 and the transmitter 2 moves. The transport progression can be reconstructed from registration of this radio cell transition and monitoring of the position is achieved.
For this purpose, the processing station 5 remains in contact via a data line with a central computer 6 of the system for monitoring transportation and positioning.
This central computer 6 has a further interface for picking up data from a receiver 9 for satellite-supported location devices 7. These satellite-supported location devices 7, which can for example be part of a GPS
navigation device, enable position monitoring in areas which are not supplied or are only inadequately supplied by a telecommunication radio cell networki this is true for example for sea routes or air transportation.
An access interface 8 of the central computer 6 now enables inquiry about data for monitoring transportation and/or positioning by someone authorised to do so, in the present case the carrier who knows the identification code. The person with authorised access can ln pre-set intervals of time, for example in times of light traffic, download the relevant information for the pertinent objects from the central computer 6 via a data network in .
CA 022~2997 l998-ll-06 order to enter said information in the person's own computer system for documentation, control and detection purposes, especially for possible insurance cases. The data stored in the central computer 6 are automatically deleted after a pre-set time to limit the volume of the data; only data about changes in movement or positioning of the respective object being transferred into the memory, likewise with a view to reducing the amount of data.
The transportation speed can be detected from the stored data stock and the arrival time of the object or objects at a pre-set destination can be determined a priori.
