4 SYSTEM DESCRIPTION
4.1 Overview
Figure 2: System Function Diagram
The CAS-CAM/RF
®
system consists of Radio Frequency (RF) Tags for each person, Light
Vehicle, Heavy Vehicle and other items of value. The Heavy Vehicle also has high quality
colour video cameras and a high definition colour LCD video Display Unit. The camera
video images and RF tagging alarms, in text format, are simultaneously displayed on the
Display Unit inside the Heavy Vehicle driver’s cabin.
The video camera is housed in a ruggedised enclosure and produces full colour vision
down to 0.03 lux illumination. Camera settings such as brightness and colour can be set
for each individual camera at the time of installation. Up to six (6) cameras can be
attached to the Display Unit (2 directly, 4 via an Expansion Unit). User programmable
camera functions include: DIM (brightness settings) and manual camera switching.
Additional programmable camera settings fixed at the time of installation include: Camera
titles (8 characters maximum), mirror / normal mode, auto switching to reverse / forward
camera when vehicle either engages reverse / forward gear or when RF detections are
recorded at the rear / front, camera cycling at variable rates. All settings are saved during
power down.
The Radio Frequency system transmits digitally coded data such as tag identification
number, tag type, vehicle status and tag status. This is crucial to the system’s ability to
discriminate when multiple tags are detected of various object classes.
A high quality, license exempt, digital RF link is used with full error control.
Personnel Tags (under development) are mounted on a safety vest and operate on
rechargeable batteries.
