Detailed Description

In order that the above-described aspects may be better understood, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Example 1

The embodiment is suitable for displaying application scenes, especially data display of a large visual screen, on a screen, and is described below with reference to a specific method.

Referring to fig. 1 to 2, a method for displaying visual data includes the steps of:

s1, acquiring a data updating period T required by a user, and dividing the data updating period T into a data grabbing period with the time of T-T and a data processing time with the time of T, wherein T and T are positive numbers, and T is larger than T;

according to the embodiment, the data missing module (T-T) +t) is built between data acquisition and data display, the data updating period is redistributed on the basis that the data updating period required by a user is not reduced, the data integrity test and the data missing are achieved, and the requirement of a customer on the data visualization large screen display effect is met.

Referring to fig. 2, the following is a specific disassembly:

t: a data update period required by a user;

T-T: the data updating period required by the user is reduced by t, namely the updating frequency is improved;

t, for data integrity verification and data complementation.

When the data updating period of the large screen display data is 30 seconds and the data processing time is 1 second, the data deficiency module (T-T) +t) automatically divides the time into 29 seconds and 1 second according to the principle of (T-T) +t, 29 seconds is a data grabbing period, and 1 second is used for deficiency and deficiency of the grabbing data.

S2, capturing the visual data in the data capturing period of each data updating period T, judging whether the visual data has missing data, if so, supplementing the missing data in the data processing time of the data updating period T, and displaying the complete visual data.

In this embodiment, step S2 specifically includes:

s21, capturing visual data through Mysql sentences in a data capturing period of each data updating period T;

s22, judging whether the visual data has missing data or not through Mysql statement.

Specifically, in this embodiment, an http+json interface protocol, a POST data submitting mode, and a mode of a signaling gateway and a media gateway are adopted to interface a standard platform and a nonstandard platform, and then platform data is read according to a split data grabbing period through Mysql statements.

S23, if so, sending a re-reading instruction of the missing data in the data processing time of the data updating period T, if the missing data is received, performing normal display, and if the missing data is not received, calculating the missing data to supplement the visual data.

In the present embodiment, the step S23 of estimating missing data to supplement the visualized data includes:

s231, reading the last data of the missing data;

i.e. the last value of missing data a is read by Mysql statement.

S232, obtaining historical average data of the latest N days of data in a time period of N times T before and after a time point of reading the missing data, wherein N and N are positive integers;

in this embodiment, n is 2 and n is 7, and step S232 is to obtain the historical average data of the last 7 days data in a time period of 1 minute before and after the time point of reading the missing data a.

S233, obtaining estimated missing data after averaging the latest data and the historical average data, and supplementing the missing data to the visual data.

In this embodiment, the missing data is calculated by adopting the method of the average value of the neighboring points according to the following formula:

missing data a' = [ data of approximately 7 days in a period of 1min before and after occurrence of missing data a +.7 +.data capture times) +last numerical value ].

That is, the number of data grasping is determined not by the total of four times each for one minute before and by 28 times for 7 days, but by the number of times actually grasped from the data source platform, and the originally estimated numerical value is eliminated, so that the estimation is performed by considering only the actual data, and the accuracy of the estimation is improved.

After that, the calculated missing data a 'is interpolated into the data extracted in the present round, it should be noted that, regarding the calculated missing data a', the format of the missing data a 'is denormalized, for example, the obtained missing data a' is 487.236, and the format of the missing data a is 487.2, where the number interpolated into the data extracted in the present round is normalized.

S24, obtaining complete visual data for display

Thus, the complete data after the deficiency is displayed on the large screen in the data updating period required by the user.

In summary, the embodiment can reduce the error rate of incomplete display or display failure caused by data missing on the basis of meeting the data updating period, and ensure the integrity and consistency of data visual display.
