PURPOSE OF THE SECURITY DEVELOPMENT BOARD
-
The Security Development board is intended to be used to
interface with the customer's Original Equipment
Manufacturer (OEM) design-under-evaluation to provide a
quick means for product development. This board provides
the standardized interconnect of peripheral circuitry to
the IPP3000 device. It provides I/O termination to
connectors. It also allows for interfacing of a
microcontroller with RS232 control. (The microcontroller
is not provided since it requires a user supplied program)
The printed circuit board was designed for multiple
applications; therefore, much of it is not loaded.
DESCRIPTION OF THE SECURITY DEVELOPMENT BOARD DESIGN:
-
The board contains the Video Perception Inc. IPP3000R
device which loads a Programmable Logic Device (PLD) to
enable it to become an IPP3000 motion detector. Three
Read-Only-Memory (RAM) devices provide the memory support
to the IPP3000 for reference image storage and masking
storage. The capacity of both the reference image and the
masking supports eight channel operation. Timing is
provided for 12 second update of the image; the user could
modify this timing by changing the R/C values. An RS232
interface is provided to a socket intended for user
insertion of a microcontroller. A RAM provides interim
storage of masking data with interconnect to the
microcontroller.
DESCRIPTION OF THE BOARD I/O PROVISIONS:
-
The board I/O are terminated at the following connectors:
J1 Connector - This connector provides for power entry to
the board, provides for the digitized image data entry,
provides for video camera timing controls, and provides for
operator controls.
P1 Connector - This connector provides for RS232 interface
to the board.
J2 and J4 Connectors - These connectors provide output
access and on board signal monitoring.
The board contains one switch (SW1) to select normal
operation or mask testing. The switch section labeled 1
is the only active section. It provides masking test
operation in the ON position.
(1) Normal Position Operation:
This is the position that would normally be selected for
operation. The Mask_In and Ref_In connections from the
IPP3000 are connected to the Mask and Reference RAMs
respectively.
(2) Mask Testing Position
Operation: This is the position that would be selected when
it is desirable to view the data stored in the Mask RAM. To
do this, the Mask_In and Ref_In connections to the IPP3000
are reversed. There must not be contrast in the camera
viewing area when doing this (cover the lens).
INPUT SIGNAL REQUIREMENTS:
-
SHADES-OF-GRAY (SOG) SIGNALS:
The SOG [0..5] signals are the most significant
bits of the digitized video data. An external A/D Converter
must be used to supply these signals.
-
VIDEO SIGNAL TIMING:
The Frame_Sync_N, Vert_Sync_N, and Line_Sync_N
timing are provided from the camera. The Clock signal is
the strobing of the A/D signal. Refer to the IPP3000 data
sheets for the timing description.
-
OPERATOR CONTROLS:
The Threshold [0..2], Tolerance [0..3], and
Edge_Change signals are controllable as described by the
IPP3000 data sheets.
-
RS-232 CONTROL:
Control can be exercised over the masking
configuration with a user supplied and programmed
microcontroller.
OUTPUT SIGNALS:
-
The Motion_Out, Motion_Sample, Alarm, MotionHalo, and
Halo_Video outputs are the typical outputs used for motion
monitoring systems. Refer to the IPP3000 data sheets.
