Link-It Active Tag 6 of 152 PERFORMANCE PARAMETERS2.1 OPERATIONAL DESCRIPTION2.1.1 Tagging SystemThe main function of the system is to monitor and control equipment, assets and people in an area or buildingin terms of position. This is done by active tags that each transmits a unique ID within a pre-set time interval.Multifunction readers, appropriately situated in the area where position monitoring has to be conducted, inter-pret signals transmitted by the tags. All tags interpreted by a specific reader are in fairly close proximity to thereader; enabling the position of the tags to be established quite accurately.The system can also monitor movement of equipment. This function is implemented by using tags designed tosense movement.2.1.2 Tags2.1.2.1 Basic TagThe basic tag can be configured to send its unique ID at a pre-set time-interval. This tag is usually used onequipment where the position should be monitored. A Tag Programmer is used to externally configure the tag.The tag is capable of transmitting its ID up to a distance of 5m. It must be however be emphasised that thetransmission range may vary from environment to environment.2.1.2.2 Tag with movement sensorThe tag with movement sensor senses movement. It transmits its unique ID at pre-set intervals, but will go intoalarm mode automatically when it senses disturbance. This type of tag is generally used on assets that shouldnot be moved, or subjected to vibration, in normal circumstances. The tag is capable of transmitting its ID upto a distance of 5m. It must be however be emphasised that the transmission range may vary from environ-ment to environment.2.1.2.3 Slimline TagThe slimline tag can be configured to send its unique ID at a pre-set time-interval. This tag is usually used onequipment and people where the position should be monitored. A Tag Programmer is used to externally con-figure the tag. The tag is capable of transmitting its ID up to a distance of 10m. It must be however be em-phasised that the transmission range may vary from environment to environment.2.2 FUNCTIONAL CHARACTERISTICS2.2.1 Tagging SystemThe system is capable of determining the relative position of tags. Tags can be attached to assets or people.

Link-It Active Tag 9 of 153 INTERFACE DESCRIPTION3.1 BASIC TAG OR TAG WITH MOVEMENT SENSORTags basically have two data interfaces that are explained in the paragraphs below.3.1.1 RF InterfaceTags are designed to operate in the more commonly known free-bands (403MHz, 868MHz). The typicalpower output is less than 100uW.3.1.2 Programming InterfaceEach Tag has to be programmed with specific variables. These variables include time-interval of its transmis-sions and the tags unique ID. A Tag Programmer is used for this purpose.
Link-It Active Tag 10 of 154 TECHNICAL DESCRIPTION4.1 PRINCIPAL OF OPERATIONThe principal of operation of the Link-It Tagging System s described in this section. A basic knowledge of thesystem is essential before commencing with any installations or implementation. A basic system block dia-gram is illustrated in Figure 4. Tags A ! N attached to assets, equipment and people are recognised and in-terpreted by a network of Readers and Repeaters. In larger areas Repeaters are used in conjunction withReaders to increase the area of operation. In smaller areas one reader will normally be sufficient to read alltags in that area. Information regarding the relative tag positions is sent via cables from readers to a PC.Large AreaReader 1Repeater 1Reader 2 Reader 3Repeater 2Repeater 3TagD TagETagCTagBTagATagMTagNTagLTagJ TagKTagITagFTagGTagHSmall AreaMedium Size AreaServerPCTagOFigure 4: Basic System Block Diagram4.1.1 TAG TO READER/REPEATER COMMUNICATIONTag to Reader/Repeater communication is done via a RF channel. The interface is described in paragraph3.1.1. Tags transmit their pre-programmed ID’s at a certain time-interval. These ID’s are received and inter-preted by the Reader/Repeater. Readers/repeaters can be configured filter data received from tags. Thismeans that only certain tags may be interpreted by the reader/repeater.Figure 5 illustrates a configuration of two repeaters (Repeater1 and Repeater2), one reader (Reader1) and12 tags (TagA ! TagL). Repeater2 can be configured to receive data only from tags except for TagE, TagF,TagG and TagH. All other tags that fall within Repeater2 receive zone will be discarded. However, this type of
Link-It Active Tag 11 of 15configuration is not recommended, but would rather be used in applications where two different systems aresituated in close proximity of each other as illustrated in Figure 6.TagAReader1Repeater2Repeater1TagCTagBTagDTagHTagETagGTagFTagKTagITagLTagJFigure 5: Tag to Reader/Repeater CommunicationTagAReader1Repeater2Repeater1 TagCTagBTagDTagHTagETagGTagFTagKTagITagLTagJSystem 1TagARepeater1 TagCTagBTagDRepeater2TagHTagETagGTagFReader1TagKTagITagLTagJSystem 2Figure 6: Tag to Reader/Repeater Communication of 2 Different Systems
