2 PERFORMANCE PARAMETERS
2.1 OPERATIONAL DESCRIPTION
2.1.1 Tagging System
The main function of the system is to monitor and control equipment, assets and people in an area or building
in 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 the
reader; 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 to
sense movement.
2.1.2 Tags
2.1.2.1 Basic Tag
The basic tag can be configured to send its unique ID at a pre-set time-interval. This tag is usually used on
equipment 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 the
transmission range may vary from environment to environment.
2.1.2.2 Tag with movement sensor
The tag with movement sensor senses movement. It transmits its unique ID at pre-set intervals, but will go into
alarm mode automatically when it senses disturbance. This type of tag is generally used on assets that should
not be moved, or subjected to vibration, in normal circumstances. The tag is capable of transmitting its ID up
to 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 Tag
The slimline tag can be configured to send its unique ID at a pre-set time-interval. This tag is usually used on
equipment 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 CHARACTERISTICS
2.2.1 Tagging System
The system is capable of determining the relative position of tags. Tags can be attached to assets or people.
