Definitions
- the invention relates to the tracking of batches of articles undergoing successive processing steps in an overall manufacturing process at a manufacturing installation. While the invention is capable of use in a wide variety of contexts, it is seen to good use in the tracking of steel slabs, blooms, billets and the like between the caster and successive rolling mills of a steel mill. For convemence, these pieces will be called by the single word "slabs" herein.
- each slab is allocated an identity, usually in the form of a number.
- the steel maker may want to carry out a number of operations on certain slabs between the caster and the rolling mill, e.g. subdivide or slit them, diffuse hydrogen out of the slab, quahty test them, send them straight for export or stock them etc. Therefore each slab must be tracked and the identity must be maintained so as not to lose them or confuse them with other slabs.
- US-A-4,642,017 discloses an automated storage retrieval system for use at a pipe manufacturing facility wherein containers for the pipes are provided with transponders which are interrogated by transmitter/receiver arrangements located on cranes which transport the containers containing the pipes.
- the results of the interrogation are stored in a computer which also monitors the loading and unloading operations of the cranes and monitors and controls the positions of the cranes on a gantry such an arrangement requires that identifiable containers are required for the batches of articles to be moved. Furthermore the identities ofthe batches of articles are not stored.
- WO-A-91/10202 discloses a manufacturing installation comprising a plurality of processing stations each arranged to perform a processing step on a batch of articles to be manufactured, the installation also having storage stations made up of storage regions, and a vehicle for moving the batches between the processing stations and the storage regions, the installation having a CPU provided with a database and arranged to track the moving of the batches by the vehicle, the installation having identifying code means and reading means arranged to read the identifying code means, the reading means and identifying code means being coupled to the CPU and arranged to automatically update the CPU with the positions of the batches.
- the invention provides an arrangement for tracking articles between sites at an installation, said the arrangement comprising:
- At least one steerable vehicle for carrying articles between said sites, said vehicle being provided with absolute position- sensing means for sensing the absolute position of said vehicle, said position sensing means having output means for outputting position signals;
- said CPU having an input coupled to said receiving means and having means for updating said database with new stored positions of said articles in response to said position signals.
- the invention provides a method of tracking articles in an installation, said installation comprising:
- At least one steerable vehicle for carrying articles between said sites, said vehicle being provided with absolute position-sensing means for sensing the absolute position of said vehicle, said position sensing means having output means for outputting position signals;
- a CPU said CPU being provided with a database for recording stored positions of said articles, said CPU having an input coupled to said receiving means and having means for updating said database with new stored positions of said articles in response to said position signals
- the absolute position of the vehicle may for example by sensed by a position-sensing means comprising a receiver arranged to receive satellite navigation signals and processing means arranged to determine the absolute position of the vehicle from timing information in the navigation signals.
- the receiver is arranged to receive Global Positioning System (GPS) signals.
- GPS Global Positioning System
- the GPS is based on a constellation of about 24 high altitude (10,900 nautical miles) satellites which transmit accurately synchronised encoded timing signals.
- An appropriate receiver at an unknown point on the earth's surface can pick up signals from three or more (preferably four) of these satellites and calculate its distance from these satellites and hence its location by comparing the time indicated by its local clock with the transmission times of the received signals.
- the signals from the fourth satellite is used to correct errors in the receivers clock by applying that correction necessary to ensure that the four computed distances from the receiver to the respective satellites are mutually consistent.
- This error can be substantially reduced by a refinement known as the Differential Global Positioning System (DGPS) wherein a local stationary receiver at a known location also receives the GPS signals from the satellites and apphes a correction to the position signal from the receiver in the unknown location, the correction being that necessary to correct the sensed position of the stationery receiver to its known true position.
- DGPS Differential Global Positioning System
- the stationary receiver is positioned at an arbitrary location and a correction signal is derived by comparing its instantaneous sensed position with its averaged sensed position.
- the correction applied by the DGPS system compensates for errors due to variations in radio propagation speed resulting from changes in the ionosphere, and relies on the assumption that such variations will be the same for the stationery receiver and the receiver whose position is to be determined.
- shielding means may be provided, e.g. a further antenna, or a dead reckoning system may be inco ⁇ orated into the system.
- DGPS receivers and associated equipment are commercially available (e.g. from Trimble Navigation Europe, Hampshire UK) and can give position signals with a repeatability ofthe order of 0.1 metre.
- an inertial navigation arrangement e.g. based on integrated circuit accelerometers with means for double-integrating the acceleration signal, i.e. a position in space independent of any local reference.
- the arrangement includes a CPU having a database which stores the identities of all the slabs by their positions in and around the steel mill or other manufacturing installation. It ' preferably has an input facility for updating and modifying data and can provide output to produce reports and to monitor progress. (It preferably also has a security system to allow access only to those who require it).
- This package can be integrated with the caster and rolling mill computers so that the database can receive instructions and confirm execution automatically, without human input.
- the CPU will receive instructions from e.g. a casting computer by radio link.
- the instructions will specify which slabs should be collected by the vehicles and where they are to be taken for storage or subsequent processing.
- the CPU will calculate the optimum storage site or position for these slabs and the optimum carrier for carrying out the transport, storing the information in the appropriate database.
- the CPU will transmit a radio signal to the computer interface ofthe selected vehicle to inform the operator that the slabs should be taken to the calculated optimum storage site.
- the radio signal will be received by an antenna on the vehicle, then demodulated and the required information displayed on the computer interface.
- the vehicle When the vehicle arrives at a slab pile, it will verify its position using its DGPS receiver, and signal this to the CPU. The verification will be displayed by the computer interface within the vehicle.
- the computer interface will display that an error has been made, and will automatically update the CPU by a radio signal so that although an incorrect pile has been picked up, the positions ofthe slabs in either pile are still known. It is possible to override this or any automatic feature ofthe CPU and this would be flagged in a report printed at the end of every shift.
- the vehicle driver then takes the slabs to the assigned station.
- the vehicle will check its position using its DGPS receiver and will transmit a further radio signal corresponding to its position within the mill. Corifirmation that this is the correct position will be displayed on the computer interface, and if it is not the correct position the operator will be informed and the CPU updated automatically by radio. In this way every slab may be tracked no matter what an operator does.
- the position by the DGPS maintains the integrity of the system whilst the immediate updating ensures that the CPU can be interrogated at any time for information concerning a given slab.
- Figure 1 is a schematic drawing of a steelworks
- Figure 2 is a schematic drawing ofthe DGPS arrangement
- FIG. 2A shows schematically the processing means and error correcting means of DGPS receiver 3, and
- Figure 2B shows a vertical position sensor of an alternative embodiment.
- a casting mould C is arranged to cast a batch B of steel slabs 5 which will require processing at a subsequent processing station PS.
- the processing steps may be rolling as in a rolling mill, scarfing, cutting, heat treatment or the like.
- storage stations SS which are divided up into storage regions SR which are parking lots for the slabs which are transported between sites using one or more vehicles V.
- Vehicle V moves the batches of slabs about the steelworks and is provided with a radio modem 2 linked to a DGPS receiver 3 in the vehicle.
- DGPS receiver 3 has a receiving antenna 6 which is arranged to receive satellite navigation signals from at least four GPS satellites 9, 10, 11 , 12 which are in high altitude orbit and were set up by the US Department of Defense.
- Receiver 3 sends sensed position signals to a stationary radio modem 2 which transmits the sensed position via antenna A to a further radio modem (not shown) which has a similar antenna A and is coupled to a caster computer CC and optionally also rolling computers (not shown).
- Our evaluations have estabhshed that the accuracy can be less than one metre which is good enough to be considered as an absolute position.
- Radio modem 2 can also receive destination position signals and other instructions from the radio modem coupled to caster computer CC and can display these instructions on a display (not shown) in the vehicle V.
- a CPU 1 is also coupled to the radio modem associated with caster computer CC and maintains a database on hard drive D which stores the updated positions of all the slabs
- a radio signal is transmitted from the antenna A associated with CPU 1 to a radio modem 2 coupled to a computer interface 3 of a vehicle V, setting out the code number ofthe location at which slabs are to be picked up and the corresponding slab identities and the code number ofthe destination station.
- a batch may need to be moved from a storage area to a processing station.
- the vehicle then travels to the storage area and on arrival the DGPS receiver 3 sends a radio signal via the radio modem 2 and antenna A to verify the vehicle position. If the sensed position corresponds to the assigned position the operator lifts the slabs and transports them to the destination station. He checks the position of that before depositing the load. He can check bis route along the roadways and can identify his location in transit to a central control on request.
- the position signals output from DGPS receiver 3 are corrected by an error signal transmitted from a stationary DGPS receiver 7 at a base station BS. This error signal is transmitted to antenna A on vehicle V from a radio modem (not shown) at the base station, via an antenna 8.
- the signals from DGPS receiver 7 are decoded in module 18 which outputs a position correction signal to processor module 19, which calculates the true position of the vehicle ' from the DGPS signals received from satellites Q9 to Q12 and from the correction signal.
- the position signal is output to radio modem 2.
- the DGPS receiver 3 may be a DSMTM 8-channel receiver as supphed by Trimble navigation
- the radio modems may be TRIOMTALKTM 450 modems from the same manufacturer
- the base station BS may be a GPS PATHFINDERTM base station, also as supphed by Trimble Navigation.
- a 3-axis accelerometer 20 replaces the DGPS receiver and sends 3 acceleration signals to a double integrator processor module 19A which outputs a position signal. If the instaUation is flat 2-axis signals should be sufficient.
- the CPU which maintains the database need not be linked to the casting computer CC but may communicate independently with the vehicle V.
- the database may be maintained by a computer on the vehicle or by the computers of aU vehicles in order to provide a multiple backup.
- the invention is applicable not only to articles which are identical within each batch but also to batches each comprising a number of different articles, in which case the identities of individual articles can be stored by preserving the relative positions and /or orientations ofthe articles within each batch as the batch is moved.
