Exam markings
Equipment And Solutions |
 |
| One of the basic requirements of on-line
markings is to capture images of huge amount within
a very limited period of time. And for this purpose
ISR8001was designed and manufactured. For several
major public exams |
|
in the mainland China,ISR8001 successfully completed
this important task and greatly impressed the officials
concerned with its speed, high accuracy, clear images
and smooth operations.
ISR8001 operates on two major data capture technologies,
namely direct data input (traditional OMR) and image based
analysis, combining the advantages of high reliability,
speed and accuracy of the former and high versatilities
of the latter---optical code reading, intelligent code
recognition and other advanced image processing technologies.
ISR8001 is unique with its 4 CPU processing and allows
image scanning speed to be in line with that of OMR---reaching
the high-speed of 2 double sided A3 per second, i e 4
A4/per second and allows scanned forms to be separated into
3 output hoppers. |
| Technical Specifications And Hardware Features |
| ISR8001 operates on window xp platform and employs 4
inter CPUs. Its closed integrated circuits design ensures
smooth operations for long operation and heavy demands |
☉Automatic Feed
☉Input hopper holds up to 1,000 forms
☉Accept hopper holds to 1,000 forms
☉Two reject hoppers, each holds up to 100 forms
☉Double sheets detector is used to detect double sheets while scanning
☉a retarder is used to assist separating sheets while scanning
☉Optional interactive transport printer to mark
each form while scanning
☉A nine inches LCD for monitoring the operation
status
☉Two 100mbps Ethernet Network Adapters to set up
server-client application
☉Duplex contact image sensors |
|
☉Simplex or Duplex imaging
☉Software control on choosing LTD colours of red,
blue, green or carbon sensitive only
illumination. It in possible for RGB working
together for capturing colour images
☉Selectable dpi of 100,133,200,300,400,as well as
8 bit greyscale
☉Reduction to binary(black and white) by critical
grey-level definition
☉Automatic saving of any defined portions or the
whole form as JPG or other formats in hard disk
or to server via network
☉Barcode reading at vertical or horizontal positions
with 4,16,256 greylevels
☉Binary digit code reading with zero reading failure
rate(BDC printing tool provided) |
|
| It takes only ONE second to scan THREE full duplex A4
forms at 100dpi or to scan TWO full duplex A3 forms at
100dpi at 256 level grey image scanning, while reading
OMR,i.e.the typical speed is over 10,000 A4 forms or 7,200 A3
forms per hour. Actual speed will be reduced slightly
by network transport speed and data processing time. As
FOUR CPUs will be working together, it could keep the
processing time at near maximum in most cases |
☉European standard of 5 tracks per
inch
☉USA standard of 6 tracks per inch
☉16 grey levels for erasure or intended marking discriminations
☉lower to reliance on cutting requirement than
traditional OMR |
