In-Depth Information
Workstation receives from signals forming
cabinets, CR position cabinets, power control
cabinets data on received and sent commands
(signals), current positions of all CR, as well as
test results (middle current of each electromagnet,
quantity of steps from lower hard support to lower
and upper limit switches, and on each section of
operating stroke, each section transmission time
and total CR movement time in performance
mode and in CR falling). The received data are
archived and displayed on the monitors. Data on
commands (signals) are sent to CIS.
Human-machine interface, which provides in-
teraction of SHC RG&IC-R with unit operational
personnel, is supported by manual control com-
mands and operator's instructions input means,
signaling and data displaying. To manual control
and operator's instructions input means belong
keys and buttons on monitoring and control
panel. Signaling means include panel “Fault”
in MCR, lightning elements of keys and buttons
on monitoring and control panel, sound devices
and workstation. Data displaying means include
indication devices in MCR and ECR, panel com-
puters, indication elements on monitoring and
control panel.
Interaction with personnel, realized mainte-
nance of SHC RG&IC-R is provided by: data
display means of operating stand-alone component
parts, set on their front panels; panel computers of
signal forming cabinets; two monitors, industrial
keyboard and laser printer of workstation.
Monitoring and control panel is equipped with
panel computer with 12” color LED-monitor.
All graphical symbols are easily read from 1.5
m distance in illumination typical for MCR. The
displayed information is arranged in form of
fragments, which are displayed on monitor by the
operator's choice. Several fragments (windows)
can be displayed on the monitor simultaneously
and show, for example, the following:
• Vertical middle position of any selected
CR group, deviation of separate CR from
the middle position, number of maximum
deviated CR, actual and maximum permis-
sible deviation;
• Vertical middle position of all CR groups
with pointing of the group, selected for
manual control, regulation group, as well
as main and auxiliary groups while moving
in a strict design order;
• Places on reactor core map of all CR within
the group selected for manual control, reg-
ulation group, main and auxiliary groups
while moving in a strict design order;
• Number of CR group controlled manually,
vertical middle position and movement
direction;
• Place on reactor core map, coordinates,
vertical position and direction of CR move-
ment, selected for individual control;
• Full data on CR, selected for individual
control (including duration of its last fail
by the ERP or RAPP command);
• Data on monitoring and control panel tech-
nical condition, received during diagnosis.
CR vertical position is displayed in digital and
quasi-analog form (vertical histograms). Data on
technical conditions are displayed in form of topo-
logical diagram, which elements are monitoring
and control panel replacement component parts.
Failed component parts are highlighted by color
change and flickering and are transferred on even
glowing after alarm message positive acknowl-
edgement by the operator. In case the position of,
at least, one CR deviates from the middle position
of the moving group for more than ± 40 mm,
and in case of generalized fault detection during
diagnosis, respective alarm message is displayed
on monitor, followed by sound signal.
Workstation is equipped with two 24” color
LED-monitors. The displayed information is ar-
ranged in form of fragments, which show:
