Abstract
A system 10 for monitoring the load on a load carrying vehicle comprises an electronic radio frequency (RF) identification system 22 comprising a reader 24 and a plurality of RF transponders 28.1 to 28.n. Each transponder is associated with a respective load item 36.1 to 36.n, and the items collectively constitute the load located in a load carrying region of the vehicle. The reader is operative in use to interrogate the transponders, to read response data received from the transponders and to generate data relating to a load change event. A controller 34 and a vehicle position data generating device 38 are connected to the controller. The controller is sensitive to a load change event and operative to record vehicle position related data corresponding to the load change event.
Claims22
A system for monitoring the load on a load carrying vehicle, the system comprising:
- an electronic radio frequency (RF) identification system comprising a reader and a plurality of RF transponders;
- each transponder being associated with a respective load item, the items collectively constituting a load located in a load carrying region of the vehicle;
- the reader being operative in use to interrogate the transponders, to read response data received from the transponders and to generate data relating to a load change event;
- a controller connected to the reader;
- vehicle position data generating means connected to the controller;
- and
- the controller being sensitive to a load change event and operative to record vehicle position related data corresponding to the load change event.
A method of monitoring a load on a load-carrying vehicle, the method comprising the steps of:
- providing on each of a plurality of items constituting a load carried on a load carrying region of the vehicle a respective transponder of a plurality of transponders of an electronic identification system;
- interrogating the transponders with an interrogation signal from a reader of the system;
- causing each transponder to respond to the interrogation signal with response date characteristic of that transponder;
- reading the data;
- comparing the data read to inventory data relating to the items in the load;
- and
- in the event of a difference between the data read and the inventory data recording a load change event and vehicle position data corresponding to the load change event.
