Embodiment
In order more to be expressly understood technology contents of the present invention, describe in detail especially exemplified by following examples.
See also Fig. 1 to shown in Figure 3, this computer based nuclear reactor safety nargin graphic early warning display method may further comprise the steps:
(1) system carries out initialization operation;
(2) the default time of system's basis is regularly taken out the security parameter of nuclear reactor the present situation from database, and this security parameter comprises nuclear power, core exit temperature, primary tank sodium liquid level, heap air cavity pressure, funnel gases radioactive dosage, a loop flow, secondary circuit flow, feedwater flow;

(6) if not, then the amplitude that departs from normal range according to described security parameter is carried out the radial deflection set handling of polygon corresponding vertex, and this processing may further comprise the steps:
(a) judge that whether corresponding security parameter currency is greater than normal range;
(b), then obtain the radially offset position of polygon corresponding vertex according to following rule if greater than normal range:

(c) otherwise, if less than normal range, then obtain the radially offset position of polygon corresponding vertex according to following rule:
Radially offset position=safe condition position-((normal range lower limit-security parameter currency)/(normal range lower limit-security parameter range minimum value)) * (safe condition position-polygon vertex smallest offset position).
Wherein, described default safe condition position is the position apart from polygon center 100 picture elements, described polygon vertex peak excursion position is the position apart from polygon center 200 picture elements, described polygon vertex smallest offset position is the position apart from polygon center 50 picture elements, can certainly set these values according to actual conditions;

(9) use the straight line of above-mentioned color to be connected to become polygon on all summits and on screen, show output.
In the middle of reality is used, method of the present invention is mainly used in SCADA (the Supervisory Control And DataAcquisition) system, be data acquisition and supervisor control, mainly finish collection, the processing of data and explain, store and show, and these real-time information are passed to other application module.Major function: information processing control, warning and processing, sequence of events recording (SOE), emergency review inverting (PDR).
For nuclear reactor, important security parameter one has 8, and these 8 parameters are respectively nuclear power, core exit temperature, primary tank sodium liquid level, heap air cavity pressure, funnel gases radioactive dosage, a loop flow, secondary circuit flow, feedwater flow.
In specific embodiments of the invention, it is regular as follows that polygon vertex is offset:
(1) when certain security parameter arrives the following range (minimum value) of its quantities, the excentric distance in the summit of this security parameter correspondence reaches recently (for example 50 pixels) simultaneously so; In like manner, when certain parameter arrived the last range (maximal value) of its quantities, the excentric distance in the summit of this parameter correspondence reached farthest (for example 200 pixels) simultaneously so.
(2) in order to guarantee whole unification directly perceived, all summits all are unified numerical value (for example maximal value all is 200 pixels, and minimum all is 50 pixels) to the ultimate range and the minor increment at center.
(3) at the place of decentering certain distance (for example 100 pixels) definition normal condition point.It is all identical that the normal condition of all security parameters is put eccentric distance.When certain security parameter was in its normal range, the summit of this parameter correspondence was located on the normal condition point.Therefore, when all 8 security parameters all just often, whole polygon just is octagon.
(4) when certain security parameter departs from normal range, its corresponding polygon vertex will move between normal condition point and maximum or the minimum position point.For example, the range of a loop flow is 0～2000, and minimum position is 50 pixels, maximum position is 200 pixels, and the normal condition point is 100 pixels, and normal range is 1000～1500, then when a loop flow was 1700, its eccentric distance in corresponding summit was:
Distance=100 pixels+((1700-1500)/(2000-1500)) * (200 pixels-100 pixel)=140 pixels.
(5) define alarm set point between normal condition point and minimax range points position, the physical location of alarm set point decides according to the actual alarm limit value of each parameter.Then when certain parameter reached the warning limit value, its corresponding summit also just moved on the corresponding alarm set point.The color of alarm set point defines according to alert levels, the corresponding yellow alarm set point of the warning of warning level, other corresponding red alarm set point of reporting to the police of failure level.
Simultaneously, the color of changeable shape depends on the highest warning color of alert levels in all security parameters.As long as promptly there is a security parameter to reach the fault limit value, then whole polygon becomes redness; As long as have a security parameter to reach the warning limit value, then whole polygon yellowing; All parameters all normally then polygon be blackish green.
Adopted above-mentioned computer based nuclear reactor safety nargin graphic early warning display method, because this method is mapped most important security parameter in the nuclear reactor respectively with polygonal summit, when all security parameters are all in normal range, be shown as a regular polygon; When one or more security parameters depart from normal range, just respective offsets is radially made on this security parameter corresponding summit on polygon, change the color on this polygon limit simultaneously, because human eye will be far longer than the sensitivity that logarithm value changes to the sensitivity of geometric deformation and color, thereby make the monitor staff can understand the current safety nargin of reactor fast according to polygonal deformation degree, help the rapid potential safety hazard of pinpointing the problems timely and hiding, can effectively avoid the generation of accident, for human and environmentAL safety provide sound assurance; Simultaneously, method of the present invention reflection is rapidly directly perceived, and operational efficiency is higher, and system stability is safe and reliable, and the scope of application is comparatively extensive, for good basis has been established in the development of the safety technique of nuclear power station.
In this instructions, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, instructions and accompanying drawing are regarded in an illustrative, rather than a restrictive.
