Introduction:
CVlM Machine Vision
Basic
Hardware
This section identifies and briefly describes the basic
hardware components for a CVIM system, namely:
l
CVIM module.
l
Pyramid Integrator chassis.
l
Chassis power supply.
l
Video monitor.
l
Light pen.
l
Camera.
l
Interface modules.
l
Interconnecting
cables.
CVIM Module
The CVIM module contains all of the machine vision
circuitry - the hardware and software that analyze the
camera's image and control the communications.
The
module occupies one slot in the chassis.
Communications
between the CVIM module and other
modules in the same chassis take place through the chassis
backplane.
Communications
between the CVIM module and external
devices take place through the front panel ports.
Pyramid Integrator
Chassis
Two Pyramid Integrator chassis are available:
One has four
slots, and the other has eight slots.
The 4-slot chassis can accommodate up to four CVIM
modules, and the 8-slot chassis can accommodate
up to eight
modules.
Chassis Power Supply
The chassis power supply plugs into the leftmost slot of the
chassis, which is dedicated to the power supply. The power
supply requires an input voltage range of either 90 to 132
VAC or 180 to 264 VAC.
The power supply provides the following DC voltage and
amperage outputs:
l
+ 5VDC @ 35A.
l
+ 12VDC @ 800mA.
0 -12VDC
@ 800mA.
