Abstract
A device for attaching to an asset in order to allow the location of the asset to be tracked. The device comprises: a hermetically sealed outer casing; and a circuit board hermetically sealed within the outer casing. The circuit board comprises a low power wireless radio frequency transmitter and electronic components for causing the transmitter to repeatedly transmit a device identifier at intervals that are randomly varied around a fixed interval.
Claims25
A device for attaching to an asset in order to allow the location of the asset to be tracked, the device comprising:
- a hermetically sealed outer casing;
- and
- a circuit board hermetically sealed within the outer casing and comprising a low power wireless radio frequency transmitter and electronic components for causing the transmitter to repeatedly transmit a device identifier at intervals that are randomly varied around a fixed interval.
A device according to any one of the preceding claims, wherein said radio frequency transmitter and said electronic components are integrated as a single integrated circuit component.
A device according to any one of the preceding claims and comprising means for fixing the device to an asset or to asset packaging.
A device for attaching to an asset in order to allow the location of the asset to be tracked, the device comprising:
- a hermetically sealed outer casing;
- a circuit board comprising a low power wireless radio frequency transmitter and electronic components for causing the transmitter to repeatedly transmit a device identifier;
- and
- a polymer gel within the casing and within which the circuit board is embedded, wherein the properties of the gel and the casing are such that they do not significantly impede signals transmitted by the radio frequency transmitter.
A computer-implemented method of determining that vehicles are parked correctly within assigned elongate loading bays of a loading yard, the method comprising:
- identifying and recording geographic coordinates defining respective longitudinally extending centre-lines of the loading bays;
- for a vehicle within the loading yard, obtaining geographic coordinates reported by two or more GNSS trackers fixed to the vehicle at spaced apart locations along the length of the vehicle;
- determining a centre-line of the vehicle using the geographic coordinates reported by said two or more GNSS trackers;
- and
- determining an alignment of the determined centre-line of the vehicle with a centre-line of an allocated one of said loading bays.
A system for determining that vehicles are parked correctly within assigned elongate loading bays of a loading yard, the system comprising:
- a server or servers for recording geographic coordinates defining respective longitudinally extending centre-lines of the loading bays;
- sets of two or more GNSS trackers, each set for fixing to a vehicle to be tracked at spaced apart locations along the length of the vehicle;
- a receiver coupled to said server(s) for obtaining geographic coordinates reported by vehicles within the loading yard,
- the server(s) being configured to determine a centre-line of a vehicle using the geographic coordinates reported by a set GNSS trackers fixed to the vehicle, and to determine an alignment of the determined centre-line of the vehicle with a centre-line of an allocated one of said loading bays.
A computer-implemented method of determining that an asset is loaded onto a given vehicle, the method comprising, at a server or set of servers,
- receiving via a data communication network a notification from a GNSS tracker located on the given vehicle that the vehicle is in motion,
- receiving from the vehicle a notification that an asset tracker located on said asset is loaded onto the given vehicle, and
- using the received information to determine that the asset is loaded onto the given vehicle and not another vehicle.
A system for detecting unauthorised access to a vehicle by a person, such as a thief or stowaway, the system comprising:
- a GNSS tracker for fixing to the vehicle, the GNSS tracker comprising a passive infra-red, PIR, detector for detecting infra-red radiation emitted from within or around the vehicle, analysing the detected infra-red radiation to determine whether a person is present in or around the vehicle, and for sending, to a server, a message comprising data indicative of a person having been detected;
- and
- a server configured to receive the message from the GNSS tracker.
A computer-implemented method of detecting unauthorised access to a vehicle by a person, such as a thief or stowaway, the method comprising:
- fixing to the vehicle, a GNSS tracker comprising a passive infra-red, PIR, detector;
- using the PIR detector to detect infra-red radiation emitted from within or around the vehicle;
- analysing the detected infra-red radiation to determine whether a person is present in or around the vehicle;
- and
- in response to determining that a person is present, sending, from the GNSS tracker to a server, a message comprising data indicative of a person having been detected.
