Week 4 - Practical (Using RFID technology to track outdoor assets)
This week journal a bit special..the classroom we reported to also a bit special..different from our original classroom..It is located at the aeroscout room..and we used a total 4 hours to complete our practical lessons!!
There are a few of the tracking systems and all of them have their own benefits in implementing.
- Able to track the vehicles in the carpark
- Updated information on vehicles informations
- Save time and cost as it locates quickly
- Accurate inventory report
- Prevent theft and misplace of vehicles
Aeroscout Architecture
We learnt about the active tags that need battery to operate on and the passive tags that do not require any batteries. Furthermore, we saw the similarities in the location receiver and a router..it looks alike, but works totally different. Location Receiver receive transmissions from AeroScout’s Wi-Fi-based Active RFID tags. They then execute sophisticated radio signal measurements and calculations that are sent to the AeroScout Engine in order to determine accurate location.
In this week practical, we used one PC pre-loaded with Tag Manager and Aeroscout Engine, Tag, Tag Activator, Access Point, Location Receiver, Wireless Bridge and Exciter. Peter made us do hands-on with these equipments to set up a tracking system outdoor and show us on how the system response. Everything was shown clealy on the screen when my classmates actually brought 2 tags outside to place. The distance shown on the computer is roughly about the calculated distance that they placed away from each other.
Tag Activator
Aeroscout Active TagsThe Tag Activator is use as a wireless bridge between the Tag Manager and software residing in the PC. I also learn from the lesson that the faster transmission interval that we set, the shorter the lifespan of the battery. We can determine that the tag activation is successful by seeing that the light on the tag is blinking.
