In one embodiment as shown in fig. 1, the present invention provides a three-dimensional visualization management system for a pipeline based on big data, comprising: monitoring a sensor and an upper computer; the upper computer comprises a communication module, a filtering module and a visualization module;
the monitoring sensor is used for monitoring the pipeline to obtain monitoring data of the pipeline;
the monitoring sensor is also used for calculating a filtering judgment value of the monitoring data in a set time period, judging whether the filtering judgment value is smaller than a set filtering judgment value threshold value, if yes, performing filtering treatment on the obtained monitoring data according to a preset first filtering treatment algorithm to obtain filtered monitoring data, and sending the filtered monitoring data to the communication module, if no, not performing filtering treatment on the monitoring data, and directly sending the monitoring data to the communication module;

the visualization module is used for displaying the filtered monitoring data in a pre-established three-dimensional model of the pipeline.
Compared with the prior art, after the monitoring sensor obtains the monitoring data of the pipeline, the filtering judgment value is calculated, when the filtering judgment value is smaller than or equal to the set filtering judgment value threshold value, the monitoring data is locally filtered, then the filtered monitoring data is sent to the upper computer, and when the filtering judgment value is larger than the set filtering judgment value threshold value, the upper computer carries out filtering treatment on the monitoring data. The second filtering processing algorithm with higher time complexity is arranged in the upper computer, so that the calculation capability requirement of the monitoring sensor is reduced.
The filtering judgment value can reflect the fluctuation condition of the monitoring data in the preset first time length, when the filtering judgment value is larger, the monitoring data change is complex, and at the moment, a filtering algorithm with stronger filtering capability is needed for filtering processing, so that the filtering judgment value is sent to an upper computer for filtering calculation, and otherwise, the filtering calculation is carried out through a monitoring sensor.
In summary, the invention can reduce the calculation capability requirement of the upper computer while ensuring the filtering effect, and balance between the calculation capability requirement and the filtering effect is achieved.
Preferably, the communication module transmits the received monitoring data which is not subjected to filtering processing to the filtering module, and transmits the monitoring data obtained after the received first filtering processing algorithm is filtered to the visualization module.
And the filtering module transmits the monitoring data obtained after the filtering processing of the second filtering processing algorithm to the visualization module.
Preferably, T is in seconds. The monitoring sensor acquires a piece of monitoring data every second.
Specifically, [ t ] m -T,t m ]The monitoring data obtained in the method is raw data which is not subjected to filtering treatment.
Specifically, the filter judgment value threshold value is obtained as follows:
the first step, the historical monitoring data of the pipeline is obtained, wherein the historical monitoring data are a plurality of monitoring data obtained in a second time length H, the unit of H is seconds, and the historical monitoring data are randomly extractedThe number of monitoring data, Z represents the total number of monitoring data obtained during the second time period H, for which +.>The monitoring data are respectively endowed with randomly generated numerical values to obtain noise adding data;
step two, initializing a filtering judgment value threshold value to be 0;
dividing the monitoring data of the noise adding data into a data set A which is more than or equal to the threshold value of the initialized filter judgment value or a data set B which is less than the threshold value of the initialized filter judgment value based on the filter judgment value;

Specifically, the filtering judgment value threshold is obtained based on historical monitoring data, wherein the historical monitoring data is filtered data. And randomly selecting a part of monitoring data from the historical monitoring data, and adding random values into the monitoring data to serve as noise, so that the noise-added data are obtained. For noisy data, since the values of the monitored data at different positions are different, different data fluctuations are introduced. The noise of the data entering the data set B is gradually increased by gradually increasing the value of the filtering judgment value threshold, and since the filtering capability of the first filtering processing algorithm is smaller than that of the second filtering processing algorithm, when the noise of the data increases to a certain extent, the first filtering processing algorithm cannot obtain a sufficiently accurate filtering result, and at this time, the filtering judgment threshold is obtained, and the filtering judgment threshold can enable the monitoring data filtered by the first filtering processing algorithm to meet the corresponding accuracy requirement.
Preferably, the upper computer can be a desktop computer, a notebook computer, a cloud server and the like.
The data in the communication module is transmitted to the filtering module through a data bus in the upper computer.
For example, the communication module may be a communication network card of the upper computer; the filtering module can be a filtering software terminal installed in the upper computer; and after the monitoring data is received by the communication network card, the monitoring data is transmitted to the filtering software terminal for calculation through a data bus on the main board.
Preferably, if the monitoring data has been subjected to the filtering process of the monitoring sensor, a corresponding identifier is added to the frame when the data of the monitoring data is transmitted, so as to distinguish whether the monitoring data has been subjected to the filtering process.
For example, the mac frame may be modified by adding an identification field between the data field and the CRC field, where 1 or 0 is filled in the identification field, 1 indicating that the filtering process has been performed, and 0 indicating that the filtering process has not been performed.
Preferably, when the data frame is encapsulated, the monitoring data which has been subjected to the filtering process and the monitoring data which has not been subjected to the filtering process may be encapsulated by different frames, and whether or not the filtering process has been performed is determined according to the type of the frame. For example, for a mac frame in which the filtered monitor data is encapsulated, an identification for discriminating is added in front of or behind the filtered monitor data in the data field. For example, letters are added for differentiation.
Preferably, the monitoring data of the pipeline is acquired at the very beginning, i.e. at time [0, E]Obtained monitoring number in time interval of (2)And directly sending the data to the upper computer. E is less than or equal to t m 。
Specifically, since the filtering judgment value of the present invention needs to refer to the monitoring data obtained in the set period of time, when the monitoring is started, the number of monitoring data cannot meet the requirement of the set period of time, and at this time, the filtering process is not performed.
Preferably, as shown in fig. 2, the monitoring sensor includes a monitoring unit, a judging unit, a filtering unit and a communication unit;
the monitoring unit is used for monitoring the pipeline to obtain monitoring data of the pipeline;
the judging unit is used for calculating a filtering judging value of the monitoring data in a set time period and judging whether the filtering judging value is smaller than a set filtering judging value threshold value or not;

the communication unit is used for sending the filtered monitoring data to the communication module, and sending the monitoring data which is not subjected to the filtering processing to the communication module when the filtering judgment value is larger than or equal to the set filtering judgment value threshold value.
Specifically, the communication unit may communicate with the communication module by means of wired communication or wireless communication.
Preferably, the communication unit communicates with the communication module via a cellular network when the pipeline is at the surface. When the pipeline is at the ground, the communication unit communicates with the communication module through wired communication modes such as optical fibers.
Preferably, filtering the obtained monitoring data according to a preset first filtering algorithm to obtain filtered monitoring data, including:
for the monitoring sensor t m Monitoring data of pipeline obtained at momentThe process of filtering it using the first filtering algorithm is as follows:
calculation ofCorresponding filter range coefficients;
acquiring a set of monitoring data for performing filtering processing based on the filtering range coefficients;
set pair based on monitoring dataAnd filtering to obtain filtered monitoring data.
In particular, in the conventional filtering algorithm, filtering is generally performed by referring to the monitoring data in a fixed range, but when the variation of the monitoring data is relatively gentle, only a small amount of monitoring data for reference is needed to obtain a correct filtering result. Therefore, the invention obtains the set of the monitoring data for filtering processing through the filtering range coefficient, so that the filtering parameter range can fluctuate along with fluctuation of the monitoring data, thereby reducing the integral calculation amount while ensuring the accuracy of the filtering result, effectively reducing the calculation force requirement of the monitoring sensor and being beneficial to saving the implementation cost of the invention.
Preferably, the filter range coefficient is calculated as:
representation->The corresponding filter range coefficient, pre, represents a preset positive integer.
Preferably, acquiring the set of monitoring data for performing the filtering process based on the filter range coefficient includes:
will beThe number of (2) is denoted->The number num of the lowest numbered monitor data in the set of monitor data for performing the filtering process min The calculation function of (2) is:
the interval of the number of the monitoring data in the set of monitoring data for performing the filtering process is
And each time the monitoring sensor obtains one monitoring data, numbering the obtained monitoring data, wherein the difference value of the numbers between two adjacent monitoring data is 1, and the numbers are sequentially increased.
Specifically, the filtering range coefficient is related to the filtering judgment value, and the larger the filtering judgment value is, the larger the filtering range coefficient is; the smaller the filtering judgment value is, the smaller the filtering range coefficient is, so that the filtering parameter range can be changed along with the change of the monitoring data.
Preferably, the pairs are based on a set of monitoring dataFiltering to obtain filtered monitoring data, including:
respectively carrying out filtering treatment on elements in a set of monitoring data for filtering treatment by using a median filtering algorithm to obtain a filtering set;
the filtered monitoring data is calculated using the following function:
representing the filtered monitored data, datset representing the filtered set, dist max Represents the elements in datset and +.>Maximum value of absolute value of difference of numbers between +.>Representing detection data Mondat in datset i And->Absolute value of the difference in number between.
Specifically, before the set of monitoring data for filtering processing is used, the elements in the set are filtered through the median filtering algorithm, so that the reference value of the elements in the set is effectively improved, the influence of noise on a filtering processing result is reduced, and the accuracy of the filtering result is improved. Because the elements in the set are elements which are not subjected to filtering treatment, if the elements are directly used, the filtering result is easy to be inaccurate due to noise.
In addition, when filtering the detection data, the number and the number of the element in the filtering setThe larger the difference between the numbers of the elements, the smaller the reference degree of the element, thereby avoiding that the element with too far distance affects the filtering result. Since if the monitored data shows a trend change, the reference value of the element with the farther number is lower, if the same reference degree is adopted, the filtering result is obviously inaccurate.
Preferably, the monitoring data of the pipeline includes the temperature of the pipeline, the humidity of the pipeline and the pressure of the pipeline.
Specifically, since the monitoring data of the pipeline has a plurality of types such as temperature, humidity, pressure and the like, the invention needs to filter each type of monitoring data respectively during filtering.
Preferably, displaying the filtered monitoring data in a pre-established three-dimensional model of the pipeline comprises:
acquiring coordinates of a monitoring sensor corresponding to the filtered monitoring data in a pre-established three-dimensional model of the pipeline;
and displaying the filtered monitoring data in the vicinity of the coordinates, wherein a line segment led out from the monitoring sensor points to the detection data during display, so that the acquisition position of the monitoring data is more visual.
Preferably, the visualization module is further configured to send a prompt to a manager of the pipeline when the filtered monitoring data exceeds the set monitoring range.
Preferably, the second filter processing algorithm includes a kalman filter algorithm, a wavelet denoising filter algorithm, or the like.
Specifically, when the second filtering algorithm is used for filtering, the reference data are all the filtered monitoring parameters.
The second filtering algorithm has higher time complexity and higher computational power requirement on the machine, but the filtering effect is better.
