Definitions

  • the present invention relates to a system, a device and a method according to the preamble of the appended independent claims. Further the invention relates to an object, such as a vehicle, a container or other equipment, provided with such a system.
  • the device for determining the position may for example be a GPS-receiver .
  • GPS-receivers receives short radio sequences from a number of satellites intended for this purpose, and can from the time difference between the reception times for the sequences from the different satellites calculate the position with a high degree of accuracy.
  • the transmitter may, for example, be a GSM-based mobile phone, or an ORBCOMM-transmitter .
  • the GPS-receiver states the calculated position of the object and the GSM-transmitter sends this to a central unit .
  • the system regularly sends position information to the central unit, but if the system is outside the area of radio coverage, the GPS-unit can no longer calculate the position of the sys- tern. If a vehicle with such as system transmits an alarm, or if the owner of a rental car or some other institution, such as police or medical services has a reason to find the vehicle quickly, they only have access to information regarding the latest position of the vehicle. If the vehicle is in a multi- storey car park, or if a person carrying such a device is in a multi-storey building, the effort needed to find the system may be considerable and the time required correspondingly long.
  • This and other purposes are achieved with a system, a device and a method according to the characterising portions of the independent claims.
  • one of, or several of, the advantageous features and functions below are achieved.
  • a system is achieved, which based on the latest stated position of the GPS-device, and using an altitude meter can calculate at least the present vertical position of the device, even though the device is out of reach of radio coverage from GPS-satellites . From the information regarding the vertical position of the device, the storey at which the device is can be calculated.
  • a device which may be manually or automatically activated to send an alarm, comprising the position of the device, to a central unit.
  • an improved device according to the invention which may be manufactured at a low cost compared to the cost of a system according to prior art, and with a reasonably low technical development effort.
  • Figure 1 schematically shows the whole system, comprising at least one object with a mobile unit 2, the GPS-satellites 8, the central unit 1 and customer units 6. It is further shown that the mobile unit 2 comprises a positioning device 4, a transmitter 3 and unit for altitude measurements 5, and that each mobile unit 2 is provided with an ID-number 7.
  • the positioning unit 4, which typically is a GPS-unit, receives radio signals from the satellites 8, and can from these signals calculate the position of the mobile unit in three dimensions.
  • the positioning unit 4 can detect that the satellite signal has disappeared, for example when the object with a mobile unit is in a garage or multi-storey building.
  • the transmitter 3 When the satel- lite signal disappears, the transmitter 3 is arranged to store the latest calculated position in the horizontal plane and calculate the high above the ground by using information from the altitude meter 5. In order to give a usable result from the method, it is assumed that the system has got out of the radio coverage area inside a building which essentially extends vertically, such as a multi-storey car park. It can then be assumed that the system is inside the building where the signal disappeared and based on information from the altitude meter the storey at which the system is can be concluded.
  • the information from the transmitter which may consist of an SMS-message, an E-mail or some other means of transferring the information, is transmitted to the central unit 1.
  • the central unit 1 stores received information for each object, and can forward it to a customer unit 6, or the central unit 1 may be situated at the customer and thus constitute the only customer unit .
  • the altitude meter 5 may be embodied in many different ways, as an example an air pressure meter can estimate the height in relation to the starting point where the GPS-receiver got outside the area of satellite radio coverage, if the air pressure in the building changes as a function of the elevation in the same way as it does outside buildings. This is fulfilled by an open car park or another open building.
  • the pressure as a function of the height above the ground for the building may be different and other kinds of measuring devices may be a better choice.
  • measuring results from an accelerometer which gives the acceleration in the vertical direction
  • a relative altitude be derived from this value
  • other kinds of gauges can be used, such as sensitive gravitation gauges.
  • the invention is also provided with an alarm switch 9, which directly or indirectly can be manually activated by the user of the system.
  • the manual alarm function can be activated with an immediate response to the user's actions, or alternatively when the user does not deactivate an automatic alarm function which reoccurs regularly with a certain time interval, or as a result of some other stimuli, such as for example that a detector senses a drastically worsened physical state of the user of the device.
  • the last example may be applicable for carriers of the device that sufferers from a heart disease, diabetes or some other disease that may demand that precise information regarding the position of the carrier rapidly reaches a hospital or some other authority.
  • a particular message is transmitted from the transmitter 3 to the central unit 1, which is forwarded, when applicable, to the correct receiver of alarms, in the figure denoted as customer units 6, which in addition to the normal information regarding position, time and the identity of the unit, states that the alarm has been acti- vated.
  • An alternative to an internal altitude meter in the system is to place local transmitters in the building that transmits a simulated satellite signal, which gives the position inside the building by radio signals which are interpreted by the re- DCver as originating from satellites.
  • the positioning unit 4 many for example cal- culate its position by using signals from GSM base stations, instead of signals from GPS-satellites.

Abstract

L'invention concerne un dispositif et un procédé permettant de déterminer la position d'au moins une unité (2) mobile munie d'un code (7) d'identité. L'unité (2) mobile comprend un récepteur (4) permettant la réception de signaux radio à partir desquels la position de l'unité (2) peut être calculée et un émetteur (3) permettant d'envoyer une information à une unité (1) centrale. Cet émetteur (3) est conçu de manière à pouvoir lire l'information dans le récepteur (4) et envoyer une information concernant au moins la position et le code (7) d'identité de l'unité (2) mobile à l'unité (1) centrale. Ce dispositif est équipé d'un appareil permettant d'effectuer des mesures (5) d'altitude, et lorsque le récepteur (4) se trouve à l'extérieur de la zone de couverture radio, il envoie à l'unité (1) centrale une information concernant le code (7) d'identité de l'unité (2) mobile, la dernière position indiquée de celui ci dans le plan horizontal, et sa position verticale donnée par le dispositif (5) permettant de mesure d'altitude. L'invention concerne en outre un véhicule, un réceptacle ou d'autres pièces d'équipement fournis avec un dispositif de ce type.
