And S103, generating a trend picture operation area while generating the trend curve.
The trend picture operation area and the data points included in the trend curve have a specific corresponding relation. The specific relationship refers to that the trend picture operation area can cover all operable points of the trend curve, so that functions of curve movement, mode change, range setting and the like are provided through the trend picture operation area. Through the functions, the display content of the trend curve can be changed, and data analysis is facilitated.
And S104, responding to the received selected operation through the trend picture operation area, and acquiring a calculation point corresponding to the selected operation on the trend curve.
And S105, calculating to obtain a target slope value according to the data values respectively corresponding to the first calculation point and the second calculation point.
When calculating the slope, the calculation is performed by using the data values corresponding to the two calculation points, that is, the calculation points include a first calculation point and a second calculation point.
In a possible implementation manner of the embodiment of the present invention, in response to receiving a selected operation through the trend picture operation region, a cursor position corresponding to the selected operation is obtained; based on the cursor position, a calculation point is determined. Namely, the trend picture can acquire the cursor position (namely the positions of the first calculation point and the second calculation point), and calculate the time and the physical value corresponding to the two calculation points. In the embodiment of the invention, the slope calculation can be carried out based on the selected time unit, namely, the slope calculation can be carried out without a fixed time unit, namely, after two slope calculation points and two time units are determined, the slope calculation result can be obtained and displayed in the corresponding text box.
In one embodiment of the present invention, in response to a change in a trend curve corresponding to the trend screen operating region, slope calculation data corresponding to the trend curve before the change is cleared.
In another embodiment of the present invention, data values of calculation points matching the cursor position are displayed at the cursor position; in response to selection of the cursor position, storing the data value such that a slope calculation is performed from the stored data value. In this way, the numerical information of the calculation point can be displayed at the position of the cursor, and the selection and the analysis of a user are convenient.
The method is described below in conjunction with a trend picture module that applies the slope calculation method, where the trend picture module is a processing unit or a portion of a processing unit in a nuclear power plant data processing system. Specifically, referring to fig. 2, a schematic diagram of a data processing flow included in the trend picture is shown. The trend screen includes a trend control section and a trend screen operating area section.
The trend control is an Active X control developed based on C + + language, which may be a small application program in nature, cannot run independently, and must be embedded in a container program (the container program is referred to as a trend screen in the present invention), and provides an interface function for calling the control for the container program. The trend control is used for displaying and drawing a trend curve, and the curve and the cursor of the control are draggable.
The trend picture is a graphical display interface developed based on C # language, which transfers the historical values (physical values and time) of the variables read from the server to the control, and the control performs curve drawing by taking the time of the historical values of the variables as an abscissa and the physical values of the historical values of the variables as an ordinate. The control is displayed on the trend screen. Meanwhile, the trend picture operation area provides functions of curve movement, mode change, range setting and the like, and a user can change the display content of the trend curve by using the functions, so that data analysis is facilitated.
In the trend screen, a trend slope calculation function is arranged in an operation area of the trend screen, and operation buttons such as a slope calculation point determination button, a slope calculation button, a time unit selection drop-down box, and the like are provided. After a trend curve to be subjected to slope calculation is selected, the trend picture can acquire the positions of the control cursor (namely the positions of a calculation point 1 and a calculation point 2) through the existing control cursor movement event interface function. Because the data of the control drawing curve are all from the picture, the time and the physical value of the point corresponding to the two calculation points can be calculated by the picture through the cursor position of the control. The trend picture respectively acquires the current control cursor position through the click event functions of the two slope calculation point determination buttons so as to obtain the data (physical values and time) of the calculation points, the data of the calculation points is based on the last click event, and the picture stores and displays the data of the two slope calculation points. Due to the readability of the slope data result, the trend picture provides a unit selection drop-down box which can be selected as time, minutes and seconds in time units. After two slope calculation points and time units are determined, a slope calculation result can be obtained. And displays the results in the corresponding text box.
In the embodiment, the data of the slope calculation point is obtained through the existing control cursor movement event interface function, and the trend control does not need to be changed any more, so the cursor function and the curve movement function of the control are not influenced at all. The trend picture can also obtain the latest calculation point data through the calculation point determination button at any time. The time unit can be selected according to requirements, and the readability of the slope calculation result is enhanced.
Referring to fig. 3, a schematic diagram of a data processing flow of slope calculation according to an embodiment of the present invention is shown. After selecting the trend curve, dragging the control cursor by a mouse to select two calculation points of the slope: moving the cursor and pressing the T1 button selects the initial calculation point, moving the cursor again and pressing the T2 button selects the final calculation point, and the values of the two calculation points are displayed in the text box. After two calculation points of the slope calculation are determined, a calculation button is pressed, and then the slope calculation result is displayed. And selecting which curve, wherein the slope function displays the slope of the selected curve, and once the selected curve is changed, the previous slope data is emptied, and a calculation point needs to be selected again for calculation.
In the embodiment of the invention, the following can be realized:
the slope calculation process has less operation steps: when the slope calculation function is used, the two calculation points are selected through the calculation point determining button, the two calculation points can be reselected at any time, and then the slope result is calculated and displayed through the slope calculation button.
The slope calculation function is arranged in the trend picture operation area and is not realized in the trend control any more, so that the curve movement function and the cursor function of the trend control are not influenced completely when the slope function is used.
The unit of slope calculation is default to seconds, but the operator can also change according to the requirement, and when the time span of two calculation points is larger, the selection of the proper time unit can make the display result more friendly.
