Description

Technical Field

[0001] The present invention relates to the technical field of monitoring equipment, and in particular to a method, system, computer and storage medium for identifying liquid leakage of monitoring equipment. Background Art

[0002] In the field of civil engineering structure safety monitoring, high-precision monitoring of the dynamic and static deformation of civil structures is the key content, so as to accurately evaluate and warn the performance and safety of civil structures.

[0003] High-precision monitoring requires the use of high-precision monitoring equipment, such as static levels and other monitoring equipment based on the principle of connecting pipes. However, as the use of this type of monitoring equipment increases, it is difficult to avoid leakage. Leakage causes the pressure of the equipment to drop to a negative value, which will cause errors in the safety monitoring of civil structures. Even liquid leakage will cause the monitoring function to fail completely. Operators need to regularly inspect and maintain the monitoring equipment to ensure that the monitoring function of the monitoring equipment operates normally.

[0004] Existing methods for identifying whether monitoring equipment is leaking often use dynamic monitoring combined with model prediction. If leakage is detected, maintenance is performed. However, in equipment based on the connecting pipe principle, when the leakage begins to occur, even if the pressure in the equipment decreases, the pressure at each point and the base point liquid level drop at the same time. The pressure difference can still reflect the actual monitoring situation. Maintenance of the monitoring equipment only needs to be performed before the liquid leaks out. Existing methods for identifying leakage lack accurate judgment of the degree of leakage, which makes it difficult to judge whether maintenance is needed and the specific time when the equipment should be repaired based on the leakage standard. Summary of the invention

[0005] In view of the shortcomings of the prior art, the embodiments of the present application provide a leakage identification method, system, computer and storage medium for a monitoring device, aiming to solve the problem in the prior art that there is a lack of judgment on the degree of leakage and it is difficult to provide specific standards and specific plans for maintenance monitoring equipment.

[0006] In a first aspect, an embodiment of the present application provides a method for identifying a liquid leakage of a monitoring device, comprising the following steps:

[0007] Acquire a number of historical monitoring days and a number of pressure data corresponding to the number of historical monitoring days from the monitoring device;

[0008] Determine whether there is a negative number in the plurality of pressure data, and if so, determine that the monitoring device is leaking and needs maintenance;

[0011] If the monitoring device meets the first leakage standard, the average value of several slopes is calculated, and based on the average value, it is determined whether the monitoring device meets the second leakage standard. If the monitoring device meets the second leakage standard, it is determined that the monitoring device is leaking and needs maintenance.

[0012] Furthermore, the step of constructing a plurality of fitting straight lines in the coordinate system includes:

[0014] Selecting a plurality of the pressure coordinate points in sequence as reference points, establishing the pressure coordinate point before the historical monitoring day at the reference point as a target point, the reference point and the plurality of the target points forming a coordinate point set;

[0015] Based on the coordinate point set, a first mean pressure value is calculated, and the first mean pressure value is associated with the reference point;

[0016] Based on the plurality of target points in the coordinate point set, a plurality of transition pressure averages are calculated, and based on the plurality of transition pressure averages and the coordinate point set, a second pressure average is calculated;

[0017] Based on the first mean value, the second pressure mean value and the coordinate point set, a slope and a fitting intercept are calculated to form the fitting straight line.

[0018] Furthermore, the step of judging whether the monitoring device meets the first leakage standard based on the time threshold and the plurality of slopes includes:

[0019] Selecting the slopes with negative values ​​from a plurality of the slopes to obtain the total number of negative values;

[0020] Comparing the total number of negative values ​​with a time threshold, and if the total number of negative values ​​is greater than or equal to the time threshold, determining that the monitoring device meets the first leakage standard;

[0021] If the total number of negative values ​​is less than the time threshold, it is determined that the monitoring device does not need maintenance.

[0022] Furthermore, the step of judging whether the monitoring device meets the second leakage standard based on the average value includes:

[0023] Comparing the average value with an average value threshold, and if the average value is less than the average value threshold, determining that the monitoring device meets the second leakage standard;

[0024] If the average value is greater than or equal to the average value threshold, it is determined that the monitoring device does not need maintenance.

[0025] Furthermore, the ratio of the time threshold to the total number of historical monitoring days is 1:2 to 4:5.

[0026] Furthermore, the value range of the average value threshold is -0.02 to 0.

[0027] Furthermore, after the step of calculating an average value of a plurality of the slopes if the monitoring device meets the first leakage standard, judging whether the monitoring device meets the second leakage standard based on the average value, and judging that the monitoring device is leaking and needs repair if the monitoring device meets the second leakage standard, the method further includes:

[0028] Based on the fitting straight line, the intersection point of the fitting straight line and the abscissa in the coordinate system is estimated to obtain the maintenance time.

[0029] In a second aspect, an embodiment of the present application provides a liquid leakage identification system for a monitoring device, which is applied to the liquid leakage identification method for the monitoring device as described in the first aspect above, and the system includes:

[0030] An acquisition module, used for acquiring a number of historical monitoring days and a number of pressure data corresponding to the number of historical monitoring days from a monitoring device;

When the computer program is executed by a processor, the method for identifying leakage of a monitoring device as described in the first aspect above is implemented.

[0037] Compared with the related art, the beneficial effect of the present invention lies in: by constructing several fitting straight lines, the changing trend of the pressure data of the monitoring equipment is digitized, and the trend is analyzed based on the slope and the fitting intercept of the fitting straight line to determine whether the monitoring equipment needs maintenance, and two standards are set on the basis of the slope analysis, thereby increasing the accuracy of the judgment of the situation of the monitoring equipment, preventing misjudgment and wrong judgment from causing equipment failure or wasting maintenance manpower. If the number of days with a negative slope exceeds the time threshold, and the average of several slopes is less than the average threshold, it is judged that the monitoring equipment not only leaks, but also needs to be repaired as soon as possible. Through the fitting straight line, the total number of days when the pressure data drops to negative pressure is predicted, which is beneficial to plan maintenance time in advance and formulate maintenance plans.

Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0042] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0044] See also Figure 1 The leakage identification method of the monitoring device provided in the first embodiment of the present invention comprises the following steps:

[0045] Step S10: obtaining a number of historical monitoring days and a number of pressure data corresponding to the number of historical monitoring days from the monitoring device;

[0046] Preferably, the monitoring equipment is based on the connecting pipe principle, and the pressure data generated is easily affected by factors such as load and temperature. Therefore, the median data from 0:00 to 8:00 every day is selected as the characteristic data of the day, and the characteristic data of several days are collected to form several pressure data corresponding to historical time.

[0047] Step S20: determining whether there is a negative number in the plurality of pressure data, and if so, determining that the monitoring device is leaking and needs maintenance;

[0048] It is understandable that if the pressure of the monitoring device drops below 0, the monitoring function of the device becomes invalid and the civil structure can no longer be monitored by the pressure difference, so a preliminary judgment is made on the pressure data.

[0049] Step S30: If it does not exist, construct a coordinate system, and construct a plurality of fitting lines in the coordinate system;

[0050] Preferably, the state of the monitoring device changing with time is reflected and predicted by a straight line graph. If the monitoring device leaks and the pressure continues to drop, the slope is negative when it is fitted into a straight line.

[0051] Specifically, the step S30 includes:

[0052] S310: sorting a number of the historical monitoring days at the horizontal axis, and filling a number of the pressure data at the vertical axis to form a number of pressure coordinate points;

[0053] Preferably, the pressure data of a certain day are associated with the corresponding monitoring time and filled into the coordinate system to obtain a plurality of fitting points.

[0054] S320: Selecting a plurality of the pressure coordinate points in sequence as reference points, establishing the pressure coordinate point before the historical monitoring day at the reference point as a target point, and the reference point and the plurality of the target points form a coordinate point set;

[0055] Preferably, by repeating the operation of S320, each of the pressure coordinate points can correspond to a coordinate point set, and a plurality of coordinate points in a coordinate point set can be fitted to obtain a straight line function, which is reflected as a fitting straight line. The fitting operation is performed on the coordinate point set corresponding to each pressure coordinate point, and the straight line function corresponding to each pressure coordinate point can be analyzed to analyze the pressure data corresponding to all the historical monitoring days and determine the change in leakage trend.

[0056] S330: Calculate a first pressure mean value based on the coordinate point set, and associate the first pressure mean value with the reference point;

[0057] Preferably, a moving average algorithm is adopted, and the denominator of the first moving average algorithm is determined according to the horizontal coordinate corresponding to the reference point in the coordinate point set, and the sum of the vertical coordinates of multiple coordinate points in the coordinate point set is the numerator, that is, the sum of multiple pressure data is the numerator, and the first mean is calculated.

[0058] S340: calculating a plurality of transition pressure averages based on a plurality of the target points in the coordinate point set, and calculating a second pressure average based on the plurality of transition pressure averages and the coordinate point set;

[0059] Preferably, a quadratic moving average algorithm is adopted. When the coordinates of several target points are used as the coordinates of the reference points, several first pressure means can be calculated. Through this operation, the several calculated first pressure means are established as several transition pressure means, and the sum is taken as the numerator. The denominator is determined according to the horizontal coordinate corresponding to the reference point in the coordinate point set, and the second pressure mean is calculated.

[0060] S350: Based on the first mean value, the second pressure mean value and the coordinate point set, a slope and a fitting intercept are calculated to form the fitting straight line.

[0061] Preferably, several fitting straight lines can be obtained through the same steps and methods, and the vertical coordinate value corresponding to a future day is calculated as the pressure prediction value based on the fitting straight line. It can be understood that the date when the pressure becomes 0 is calculated with the pressure prediction value being 0, and the maintenance time can be planned according to the calculation result.

[0062] Step S40: extracting the slope of the fitting straight line, and judging whether the monitoring device meets the first leakage standard based on a time threshold and a plurality of the slopes;

[0063] Leakage of the monitoring equipment is a process in which the slope fitted by daily data is negative for a long time. It is necessary to continuously evaluate the slope within a certain period of time. Therefore, the time threshold is set. When the number of days with negative slope in several historical monitoring days exceeds the number of days with the time threshold, it is determined that the monitoring equipment is leaking. It can be understood that setting the first leakage standard is beneficial to improving the accuracy of judging the leakage situation. If the judgment is made based on whether the slope is negative for many consecutive days, misjudgment or missed judgment is prone to occur.

[0064] The ratio of the time threshold to the total number of historical monitoring days is 1:2 to 4:5.

[0065] Preferably, the total number of historical monitoring days is 10 days, and the time threshold is 7 days.

[0066] Specifically, the step S40 includes:

[0067] S410: Selecting the slope with a negative value from the plurality of slopes to obtain the total number of negative values;

[0068] S420: comparing the total number of negative values ​​with a time threshold, and if the total number of negative values ​​is greater than or equal to the time threshold, determining that the monitoring device meets the first leakage standard;

[0069] S430: If the total number of negative values ​​is less than the time threshold, it is determined that the monitoring device does not need maintenance.

[0070] Advantageously, among the 10 historical monitoring days, 7 days have a negative slope, which means that the equipment needs maintenance. It can be understood that if the total number of negative values ​​is less than the time threshold, it means that the monitoring equipment may be leaking. However, even if the pressure drops, the civil structure can still be effectively monitored by the pressure difference.

[0071] Step S50: If the monitoring device meets the first leakage standard, calculate the average value of several slopes, and determine whether the monitoring device meets the second leakage standard based on the average value. If the monitoring device meets the second leakage standard, determine that the monitoring device is leaking and needs maintenance.

[0072] It can be understood that if the slope value is too small and the pressure data has a clear downward trend, it means that the monitoring device has leaked.

[0073] The value range of the average value threshold is -0.02 to 0.

[0074] Preferably, the average value threshold is selected as 0.01.

[0075] Specifically, the step S50 includes:

[0076] S510: comparing the average value with an average value threshold, and if the average value is less than the average value threshold, determining that the monitoring device meets the second leakage standard;

[0077] S520: If the average value is greater than or equal to the average value threshold, it is determined that the monitoring device does not need maintenance.

[0078] It can be understood that if the average value is greater than or equal to the average value threshold, it means that the downward trend of the pressure data is not obvious enough, and the monitoring equipment may be leaking, but there is no need to repair the equipment at this time, which can save the cost of scheduling maintenance.

[0079] S530: Based on the fitting straight line, estimate the intersection point of the fitting straight line and the abscissa in the coordinate system to obtain a maintenance time.

[0080] Substituting 0 as the ordinate value into the fitting straight line, that is, the fitting straight line intersects the abscissa, the number of days required for the pressure at the equipment measuring point to drop to 0 can be deduced based on the trend, and a maintenance plan can be arranged based on the derivation result.
