Description

USER DEVICE, SYSTEM AND METHOD This invention relates to a user device, system and method, in particular for location tagging.
There are a number of situations in which objects may be tracked to know their geographical position, or located in a specific geographical position by means of fixed or mobile readers, e.g. radio frequency identification (RFID), where an RFID tag passing a reader sends information on its identity to the reader; or livestock tracking systems (GB-A-23 87465) in which a built-in satellite navigation circuit transmits location information and identity from the animal at certain time intervals. Another system (W02008076235) uses satellite navigation system co-ordinates, pre-programmed into a component, so that the component can be positioned at a desired geographical location within a network, i.e. located, in order to construct the network correctly.
In accordance with a first aspect of the present invention a user device for a location tagging system comprises a location information source and a tag deployment device.
The user device has a source of location information, so that a tag deployed from the deployment device is given an associated location of the object on which it is deployed, thus providing object location. For objects that will remain at fixed positions for long periods of time, the invention avoids the need for the object to have its own location information source built in, so reducing cost and complexity. In addition, the present invention enables these objects to assist in location of mobile devices, when they come within range, which do not have any location information of their own.
Preferably, the tag deployment device provides a fixing, to fix the tag to an object on deployment. The fixing may comprise one of adhesive, staples, screw fixing, or insertion into a corresponding receptacle on the object.
Preferably, the tag deployment device further comprises a tag store and a tag selector.
Preferably, the user device further comprises a cellular communication device.
In one embodiment, the location information source comprises a satellite system. The satellite system may be augmented using assistance from a cellular mobile network.
Alternatively, the location information source is a terrestrial ultrawideband location system.
In accordance with a second aspect of the present invention a location tagging system comprises a user device according to the first aspect and one or more tags.
Preferably, each tag is allocated a unique tag identifier. The tag identifier may be allocated by the user device, or alternatively, the tag identifier is allocated during manufacture.
Preferably, the user device further comprises a store to store a record of tag identifier and tag location for each deployed tag.
Preferably, the system further comprises a central store to receive tag identifier and tag location from the user device store.
Preferably, the user device communicates with the central store via the cellular communication device.
Preferably, the user device communicates with the or each tag by means of one of contact connections, capacitive coupling, wireless communication, or radio frequency identification technology. In one embodiment, the user device communicates with the or each tag using Bluetooth short range wireless protocol.
Preferably, the system further comprises a display.
Preferably, the tag deployment device comprises a trigger, wherein the trigger causes the device to fix the tag to the object, substantially simultaneously with the location information source providing location information to the tag.
Preferably, the trigger causes the unique tag identifier and tag location to be displayed on the display before operation of the tag deployment device occurs.
In accordance with a third aspect of the present invention, a method of deploying a location tag on an object comprises determining from a location information source in a user device, the location of the user device; supplying the location information to a tag; and operating a tag deployment device to deploy the tag on the object.
Preferably, the user device selects a tag from a store in the user device for deployment.
Preferably, operation of the tag deployment device further comprises applying a fixing to fix the tag to the object.
Preferably, the fixing comprises one of applying adhesive to the tag; stapling the tag; screwing the tag onto the object; or inserting the tag into a receptacle on the object.
Preferably, the location information is supplied to the tag by means of contact connections, capacitive coupling, wireless communication, or radio frequency identification technology. The user device may communicate with the or each tag using Bluetooth short range wireless protocol.
In one embodiment, the method further comprises allocating a unique identifier to the tag before deployment. Alternatively, the unique identifier is allocated during manufacture.
Preferably, the method further comprises storing a record of the unique identifier and corresponding location information for the tag in a store in the user device.
In one embodiment, the method further comprises transferring the record to a central store via wireless communication. Alternatively, multiple records may be stored on the user device and the method further comprises transferring the or each record to a central store via wired or short range wireless communication at a network central location.
The method may further comprise depressing a trigger to a first level to display the unique identifier and location information; and depressing the trigger to a second level to initiate deployment of the tag. Alternatively, the method further comprises initiating deployment of the tag, substantially simultaneously with providing location information to the tag.
Rather than dispose of tags when they are no longer required on a particular object, preferably, the method further comprises clearing stored information on the tag, removing the tag from the object and making the tag available for redeployment on a new object.
An example of a user device, a location tagging system and a method of location tagging according to the present invention will now be described with reference to the accompanying drawings in which: Figure 1 illustrates an example of a system according to the present invention; and, Figure 2 illustrates an example of an application of the system of Fig. 1.
The present invention provides a system in which a tag having a unique identifier may be fixed to an object and a location of that tag and hence the object, stored during deployment. The location may be stored in the tag, or else the user device stores a correlation of the tag identifier and deployment location in a user device store. This information may then be used by other users which move into the vicinity of the object, so that those users can determine their location, either received directly from the tag, or obtained from the correlated data which has been transferred to a central store in a network and stored, for example as described in our co-pending UK patent application no.08 17384.1 The tag may be of any suitable type, such as an electronic label, a transponder, an RFID tag, or other read/write element. In its most basic form, the tag has an identifier which can be read e.g. by a passing mobile device and all other information relating to the object on which the tag has been deployed is obtained by the mobile device, via the network. More advanced tags may store information which is directly accessed by the mobile device.
The example of Fig. 1 illustrates a system for location tagging. In this example, the system comprises a user device 1, typically handheld, including a location information source 2, such as a global navigation satellite system (GNSS) terminal, e.g. global positioning system (GPS) terminal; a tag deployment device comprising a tag store 3, a tag selection device 4 and tag fixing 5. The selection device 4 and tag fixing may be operated by a trigger 6, controlled by a processor 7, or simply under processor control following a user instruction. The user device may also include a display 8. In the example of Fig. 1, the tag store 3 and tag selection device 4 are shown as being integral to the tag deployment device in the user device 1. However, in an alternative embodiment, not shown, tags may be provided separately from the user device, so the store 3 and selection device 4 are not part of the tag deployment device of the user device 1, whilst the fixing 5 and location information 2 is still supplied by the user device 1. Further optional features of the system are the provision of a connection 9 to a network 10, with a central store 11, SO that the correlation of the unique identifier on each tag which is deployed, together with the location of the tag when deployed, may be stored for subsequent use. This connection may be performed wirelessly, for example, using an integral cellular phone. Alternatively the connection may be performed by a wired or short range wireless connection at period intervals when the user device is returned to a base location. A tag 12 after deployment is shown on an object 13.
The system of the present invention combines the functions of determining its own and therefore an object's, location, using a tag with a unique identifier to associate that infonTnation with and optionally to also receive and store that information. The user device communicates digital information defining the location to the tag for the object over a suitable interface and provides means to fix the tag to a surface of the object.
The unique identifier may be allocated and stored on the tag as part of the manufacturing process or may be generated by the user device and written to the tag during the deployment process. By applying a part of the identifier which is dependent upon which user device generates the reference, a unique identifier may still be generated, despite multiple user devices being in use.
In a preferred embodiment, the user device is arranged such that a single operation, such as pulling the trigger, by an operator initiates the operation of determining location, communicating that to the tag and fixing the tag to the object.
This combined operation is simple and convenient for the user.
A further feature which may be applied using the trigger arrangement, is that partial activation e.g. by squeezing, but not fully compressing the trigger 6, gives an indication of whether an acceptable position fix has been obtained by displaying the position fix on the display 8, or simply operating a some kind of indicator system, such as traffic lights, to let the user know whether a fix with an acceptable level of certainty had been obtained. Thus, the position can be obtained and held before initiating the fixing of the tag 12 to the object 13, SO that if the particular location does not allow for a satisfactory fix, the processor may be set up to override the full depression of the trigger to prevent the fixing taking place, or else allow the fixing, but ensure that the position is marked as being suspect when recorded. Similarly, the processor 7 may override full depression of the trigger if the processor has not received an indication of satisfactory completion of the communication of the location information to the tag, whether or not the position location was reliable.
However, another option is that tags may be supplied on the objects and remain dormant until the user device is brought into their vicinity, at which point the location is communicated to the tag, the corresponding unique identifier is received from the tag, or written to it, according to the method in use and the identifier is stored in association with the location. A fixing, for example a seal, may be applied to the tag 12 on the object 13, to indicate that its location and identifier have been recorded.
An implementation in which a GNSS receiver is incorporated into the user device is the most convenient way of providing the function of determining the position of the user device and hence a tag being deployed, but an alternative is to use assisted GNSS, where an incorporated mobile phone provides collateral information to the GNSS receiver to allow improved location fixing. Alternatively, position fixing may be obtained using terrestrial infrastructure such an ultra wideband (UWB) location system.
Whether or not the tags 12 are stored 3 and processed 4 within the user device 1 before deployment, the means of communicating digital information regarding the tag location from the location information source to the tag may use any suitable means of connection. Examples include contact connections, capacitive coupling, wireless communication, such as Bluetooth short range wireless protocol, or radio frequency identification (RFID) technology.
Fixing the tag to the object 13 may be carried out by means of a staple-gun action, to cause a staple or staple-like device attached to the tag 12 to be forced into a surface of the object. Alternatively, the user device may dispense adhesive into a gap between the surface of the object and the surface of the tag being fixed, or remove a cover from an adhesive layer applied to the tag during manufacture and if necessary cause the two surfaces to be pressed together. Another option includes applying a drill action to cause a captive screw to create its own hole, thereby screwing the tag onto the surface of the object. Tn some cases, the object may be provided with a receptacle of a suitable size, so that a tag can be dropped in and remain in place by the effect of gravity. This is particularly suitable for tags which may be subsequently redeployed.
If desired a seal may be applied to discourage removal of the tag from its location, or an electronic seal to prevent inadvertently over-writing the tag until it is actually desired to remove it from that location.
In the present invention, the user device may incorporate a location information source, such as GPS, which regularly computes a position fix and updates the information by saving the latest position to tags within the system. In this case, initiation of the deployment operation does not explicitly activate the storing of the location information on the tag, but simply uses the deployment phase to fix the tag to the object and disconnect the tag from the location updating, so that the last saved position before disconnection is the one which is associated with that tag's unique tag identifier.
Having installed the tags, Fig. 2 illustrates an example of how they may be used subsequently, in association with the correlation of tag identifier and position location co-ordinates stored in the central store. Each object 14, 15, 16 in Fig. 2 has a tag Ti, T2, T3 deployed on it. A mobile device Mi finds itself within range of a tag T2 which has been installed at a remote monitoring station, monitoring air quality. The tag communicates with the mobile device using Bluetooth and transmits its unique identifier. The mobile device Mi forwards this information to its network 10 and the network looks up the correlation of identifier and location in its central store 11. From this, the network may inform the mobile device of its location, or may choose to send back other data which is related to the mobile device being in that location. In the case where the tag stores both its identifier and its location, the mobile device Mi may simply forward both pieces of data to the network which responds accordingly.
A further feature of the invention is that the tags may be reused. For example, monitoring at a remote station may only be required for a particular period of time, or until a certain quality level is achieved, after which the tag can be removed and redeployed elsewhere. A seal, either electronic or physical may have been applied to the tag when first installed and for the electronic seal, this needs to be disabled by the user device before removing the tag, clearing any stored information, other than its identifier and then returning the tag to the pool of tags available to the user device.
