[0020] Embodiment one

[0021] As shown in the figure, the present application provides a water conservancy project safety monitoring method, wherein the method is applied to a safety monitoring system, the safety monitoring system comprises a flow collection device, and the method comprises: Figure 1 Step S100: collecting target water conservancy project basic information based on big data, wherein the target water conservancy project basic information comprises location information and working information;

[0022] Specifically, the target water conservancy project is any water conservancy project that needs to be safety monitored. The basic information is information reflecting the construction purpose and running state of the water conservancy project. The location information is information reflecting the geographical position of the water conservancy project. The working information is working data generated in the working process of the water conservancy project. The basic data is provided for subsequent analysis of the running state of the target water conservancy project.

[0023] Step S200: filtering upstream and downstream water conservancy project sites according to the location information to obtain an upstream and downstream site set;

[0024] Further, as shown in the figure, the filtering of the upstream and downstream water conservancy project sites according to the location information, the step S200 of the embodiments of the present application further comprises:

[0025] Figure 2 Step S210: collecting upstream and downstream branches by using a positioning system according to the location information to obtain an upstream and downstream branch set;

[0026] Step S220: filtering the upstream and downstream branch set according to a preset flow threshold to obtain a key watershed set;

[0027] Step S230: obtaining site information closest to the target water conservancy project according to the key watershed set to obtain the upstream and downstream site set.

[0028] Step S230: obtaining site information closest to the target water conservancy project according to the key watershed set to obtain the upstream and downstream site set. ​

[0029] Specifically, the target water conservancy project is located according to the position information, and the upstream and downstream branch collection is obtained according to the hydrological distribution information. The upstream and downstream branch collection contains the upstream and downstream tributaries of the target water conservancy project. The preset flow threshold is the maximum flow of the upstream of the target water conservancy project that has an impact on the target water conservancy project, and the maximum flow of the target water conservancy project that has an impact on the downstream branch. The upstream and downstream branch collection is filtered according to the preset flow threshold to obtain the affected upstream and downstream branch, and the key watershed set is formed. From the key watershed set, the station information is obtained according to the shortest distance of each branch from the target water conservancy project to form the upstream and downstream station set. The target of obtaining the target water conservancy project influence station is achieved, and the technical effect of providing basic data for subsequent upstream and downstream influence determination monitoring scheme is achieved.

[0030] Step S300: collecting water level and flow information of the upstream and downstream station set in real time through the flow collecting device to obtain a water level-flow data set;

[0031] Further, as shown in the figure, Figure 3 The step S300 of the embodiment of the application further includes:

[0032] Step S310: measuring the water level and flow of the stations in the upstream and downstream station set through the flow collecting device to obtain a plurality of measured flow results tables;

[0033] Step S320: drawing a plurality of water level-flow relationship curves, water level-area relationship curves and water level-flow velocity relationship curves according to the data in the plurality of measured flow results tables;

[0034] Step S330: checking a plurality of water level-flow relationship curves according to the plurality of water level-flow velocity relationship curves and the plurality of water level-area relationship curves to obtain a plurality of approved water level-flow curves;

[0035] Step S340: obtaining the water level-flow data set based on the plurality of approved water level-flow curves.

[0036] Specifically, the flow acquisition device is a device for measuring water flow, and optionally includes a radar flowmeter, an electromagnetic flowmeter, etc. By collecting the water levels and flows of multiple sites, multiple measured flow result tables are obtained. The measured flow result table is real-time collected water level and flow information, and the water level and flow are one-to-one corresponding. Further, by plotting the data in the measured flow result table in the coordinate axes with the water level as the horizontal coordinate and the flow, area and flow rate as the vertical coordinates, corresponding relationship curves are obtained. The water level-flow relationship curve reflects the relationship change between the water level at the water flow section and the flow through the section; the water level-area relationship curve reflects the relationship change between the water level at the water flow section and the area of the section; and the water level-flow rate relationship curve reflects the relationship change between the water level at the water flow section and the flow rate of the water flow through the section. The multiple water level-flow rate relationship curves and multiple water level-area relationship curves are used to check the multiple water level-flow relationship curves, and the water level-flow curve is adjusted according to the product of the flow, area and flow rate. According to the calibrated water level-flow curve, the water level-flow data set is obtained. The technical effect of improving the accurate collection of the water level-flow and improving the accuracy of the data is achieved.

[0037] Step S400: performing data analysis according to the water level-flow data set to obtain a water level difference value data set of adjacent sites and a flow difference value data set of adjacent sites;

[0038] Specifically, the data analysis is performed by obtaining the water level-flow data of adjacent sites multiple times from the water level-flow data set, performing difference, obtaining multiple water level difference values of adjacent sites and flow difference values of adjacent sites, and summarizing to obtain the water level difference value data set of adjacent sites and the flow difference value data set of adjacent sites. Whether the water level difference value and the flow difference value of adjacent sites are stable affects the time point and the number of monitoring of the water conservancy project. Therefore, the technical effect of improving the accuracy of monitoring is achieved.

[0039] Step S500: determining whether the target water conservancy project is in a flood discharge period according to the work information, and obtaining a flood discharge period data set if it is in the flood discharge period;

[0040] Further, the step S500 of the embodiment of the present application further includes:

[0041] Step S510: obtaining real-time water level information and real-time flow information of the target water conservancy project based on the work information;

[0042] Step S520: determining whether the real-time water level information exceeds a predetermined water level threshold to obtain a water level determination result;

[0043] Step S530: judging whether the real-time flow information exceeds a predetermined flow threshold, to obtain a flow judgment result;

[0044] Step S540: judging whether the target water conservancy project is in a flood discharge period according to the water level judgment result and the flow judgment result, to obtain a period judgment result.

[0045] Further, the application embodiment step S540 further comprises:

[0046] Step S541: obtaining upstream and downstream water quantity information and water level change information according to the working information;

[0047] Step S542: determining a flood discharge stage of the target water conservancy project according to the upstream and downstream water quantity and the water level change information;

[0048] Step S543: obtaining a corresponding flood discharge period data set according to the period judgment result and the flood discharge stage.

[0049] Specifically, the real-time water level information is information reflecting real-time change of the water level of the target water conservancy project. The real-time flow information is information reflecting real-time change of the flow section of the target water conservancy project. The predetermined water level threshold is the lowest water level for the target water conservancy project to enter the flood discharge period. By judging whether the real-time water level information exceeds the predetermined water level threshold, the water level judgment result can be obtained. When the predetermined water level threshold is exceeded, the water level judgment result is that the water level of the target water conservancy project meets the requirement of entering the flood discharge period. The predetermined flow threshold is the lowest flow for the target water conservancy project to enter the flood discharge period. By judging whether the real-time flow information exceeds the predetermined flow threshold, the flow judgment result can be obtained. When the predetermined flow threshold is exceeded, the flow judgment result is that the flow of the target water conservancy project meets the requirement of entering the flood discharge period. When both the water level and the flow meet the requirement of the flood discharge period, it can be judged that the target water conservancy project is in the flood discharge period, that is, the period judgment result.

[0050] Specifically, the upstream and downstream water quantity information is relationship information between upstream inflow and discharge. The water level change information is a reservoir water level change condition of the target water conservancy project. The flood discharge stage includes a flood discharge initial stage, a continuous stable flood discharge stage and a flood discharge final stage. When the upstream inflow is greater than the discharge, and the reservoir water level rises, it can be judged that the target water conservancy project is in the flood discharge initial stage; when the upstream inflow is less than the discharge, the reservoir water level falls, and the continuous stable discharge is less than the discharge in the initial stage, it can be judged that the target water conservancy project is in the flood discharge final stage; when the upstream inflow is greater than the discharge to a stable degree, and the reservoir water level is also in a stable state, it indicates that the target water conservancy project is in the continuous stable flood discharge stage. According to the corresponding flood discharge stage, the corresponding flood discharge period data set is collected. The flood discharge period data set is data reflecting the working state of the target water conservancy project in the flood discharge period, including gate opening and closing quantity, weir hole information, flow and water level and other data. Thus, the technical effect of improving the accuracy of data by collecting data according to different stages is achieved.

[0051] Step S600: inputting the adjacent station water level difference data set, the adjacent station flow difference data set and the flood discharge period data set into a monitoring scheme model to obtain a flood discharge period monitoring scheme;

[0052] Further, the inputting the adjacent station water level difference data set, the adjacent station flow difference data set and the flood discharge period data set into the monitoring scheme model to output the flood discharge period monitoring scheme, the embodiment step S600 of the application further comprises:

[0053] Step S610: constructing the monitoring scheme model, including an initial monitoring scheme model and a correction scheme model;

[0054] Step S620: inputting the flood discharge period data set into the initial monitoring scheme model to obtain an initial monitoring scheme;

[0055] Step S630: inputting the adjacent station water level difference data set, the adjacent station flow difference data set and the initial monitoring scheme into the correction scheme model to obtain a flood discharge period monitoring scheme.

[0056] Specifically, the monitoring scheme model is a function model for generating a water conservancy monitoring scheme, including the initial monitoring scheme model and the revised scheme model. The initial monitoring scheme model is a function model outputting an initial monitoring scheme without considering the upstream and downstream influences according to the flood discharge period data of the target water conservancy project. The revised scheme model is a function model for revising the initial monitoring scheme by considering the water level difference and flow difference between adjacent sites and real-time water regime. By combining the factors of the target water conservancy project itself and the upstream and downstream influencing factors, an accurate flood discharge period monitoring scheme is obtained. Thus, the accuracy of the monitoring scheme is improved, the intelligent degree of monitoring is improved, and the monitoring cycle is shortened.

[0057] Step S700: According to the flood discharge period monitoring scheme, the target water conservancy project is monitored.

[0058] Further, the step S700 of the embodiment of the application further includes:

[0059] Step S710: When the target water conservancy project is in a non-flood discharge period, obtain downstream jacking distance and water temperature information;

[0060] Step S720: Determine whether the downstream jacking distance exceeds a predetermined jacking distance, and if so, obtain an initial non-flood discharge period monitoring scheme;

[0061] Step S730: According to the water temperature information, the initial non-flood discharge period monitoring scheme is revised to obtain a non-flood discharge period monitoring scheme;

[0062] Step S740: According to the non-flood discharge period monitoring scheme, the target water conservancy project is monitored.

[0063] Specifically, the downstream jacking distance is the distance of water flow backflow when the upstream water meets the obstruction due to the opening of more gates and deep-hole gates for flood control storage of upstream water at downstream sites. The water flow backflow will cause the water level of the upstream water area to rise, and when the backflow distance exceeds the predetermined jacking distance, it will affect the monitoring of the target water conservancy project. Thus, when the downstream jacking distance exceeds the predetermined jacking distance, an initial non-flood discharge period monitoring scheme is obtained. The predetermined jacking distance is the maximum distance at which downstream backflow does not affect the monitoring of the target water conservancy project.

[0064] Specifically, the water temperature information is the temperature of the water flow at the target water conservancy project. If the water temperature is high, the aquatic plants in the water area grow vigorously, the roughness of the river channel increases, and the flood carrying capacity will decrease. Therefore, the initial non-flood discharge period monitoring scheme needs to be modified according to the water temperature information to obtain the non-flood discharge period monitoring scheme. Thus, the technical effect of determining different monitoring schemes according to different periods of the target water conservancy project is achieved, and the monitoring accuracy and efficiency are improved.

[0065] In summary, the water conservancy project safety monitoring method provided by the present application has the following technical effects:

[0066] 1. The present application collects the position information and working information of the target water conservancy project based on big data, then filters the upstream and downstream water conservancy project sites according to the position information to obtain a set of upstream and downstream sites, collects data information through a flow collection device to obtain a water level-flow data set, then analyzes the data based on the water level-flow data set to obtain a set of adjacent site water level difference data and a set of adjacent site flow difference data, and then determines whether the target water conservancy project is in the flood discharge period. If it is, a flood discharge period data set is obtained, and the set of adjacent site water level difference data, the set of adjacent site flow difference data, and the flood discharge period data set are input into a monitoring scheme model to obtain a flood discharge period monitoring scheme for safety monitoring of the target water conservancy project. The technical effects of improving the intelligent degree of safety monitoring, shortening the monitoring time, and improving the monitoring quality are achieved.

[0067] 2. The present application collects the water level and flow of the stations in the set of upstream and downstream stations to obtain a plurality of measured flow results tables, then draws a plurality of water level-flow relationship curves, water level-area relationship curves, and water level-flow velocity relationship curves, checks a plurality of water level-flow relationship curves according to the relationship between flow, area, and flow velocity to obtain a plurality of approved water level-flow curves, and then obtains a water level-flow data set. The technical effects of improving the accurate collection of water level-flow and improving the accuracy of data are achieved.
