Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, and in particular to an integrated water quality multi-parameter rapid detection device based on multi-channel switching. Background Art

[0002] Multi-parameter water quality detection ensures the stability of the ecosystem by real-time monitoring of pH, dissolved oxygen, heavy metals, microorganisms and other indicators, avoids the deterioration of the living environment of aquatic organisms and ecological imbalance due to changes in water quality, meets the strict requirements of industrial production on water quality, and ensures product quality and production efficiency. At the same time, it helps environmental regulatory departments to accurately obtain water quality information, trace and control pollution sources, and promptly warn of sudden water pollution incidents, thereby achieving sustainable use of water resources.

[0003] However, in the traditional multi-parameter water quality detection process, there is a lack of synchronous monitoring of water quality at multiple depths and dynamic buoyancy adjustment to ensure the stability of the sampling position, resulting in insufficient data representativeness. In addition, the flow path switching only relies on simple structures or manual operations, which makes it difficult to meet the needs of rapid multi-parameter detection in complex waters. In addition, data processing only stays at the level of independent detection of a single parameter. A multi-dimensional data fusion analysis system and dynamic simulation model have not been constructed. It is impossible to combine water quality characteristics, external environment, sampling risks and other parameters for comprehensive risk assessment and trend prediction, resulting in limited risk identification accuracy and intelligent decision-making level. Summary of the Invention

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an integrated water quality multi-parameter rapid detection device based on multi-channel switching, comprising a detection device body, wherein a multi-channel sampling unit, a flow path switching unit, a detection unit and a control unit are arranged inside the detection device body;

[0006] The multi-channel sampling unit includes multiple groups of water pumping pipes arranged at different depths below the water area, and each group of water pumping pipes is provided with a water inlet and a filter screen;

[0007] The flow path switching unit includes a multi-channel valve and a drive motor, and the multi-channel valve is connected to each set of water pumping pipes through a pipeline;

[0008] The detection unit includes a plurality of water quality parameter sensors, and the water quality parameter sensors are used to measure multi-parameter indicators of water samples;

[0009] A control panel is provided inside the control unit, and a display screen is provided on the control panel. A suspension component is fixedly installed on the outer side of the water pumping pipe below the water surface, and a suspension sphere for suspending the water pumping pipe is provided between the water pumping pipe and the main body of the detection device.

[0010] Furthermore, a water quality monitoring platform is provided inside the control panel, and the water quality monitoring platform is communicatively connected to a water area model unit, a data acquisition unit, a parameter analysis unit, an abnormality feedback unit, a comprehensive evaluation unit and an early warning processing unit;

[0025] The water quality risk assessment coefficient SZPGi is calculated according to the formula and compared with the preset threshold YTSZPGi. If the ratio is ≥1, a control signal is generated; if the ratio is <1, a feedback instruction is generated.

[0026] Furthermore, when the comprehensive evaluation unit generates a feedback instruction:

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1: Figure 1-Figure 3 As shown, the integrated water quality multi-parameter rapid detection device based on multi-channel switching includes a detection device body 1, in which a multi-channel sampling unit, a flow path switching unit, a detection unit and a control unit are arranged;

[0040] The detection unit is connected to the flow path switching unit, and the detection unit includes a plurality of water quality parameter sensors, which are used to measure multi-parameter indicators of the water sample;

[0041] The control unit is electrically connected to the flow path switching unit and the detection unit. A control panel 501 is provided inside the control unit, and a display screen is provided on the control panel 501. A suspension assembly is fixedly installed on the outer side of the water pumping pipe 201 below the water surface.

[0042] It can stably float on the surface of the water area to be tested. It should be explained here that a plurality of propellers are arranged in a circular array below the suspending sphere 6 with the center of the suspending sphere 6 as the center. The propellers are driven by an external motor. The multi-directional motor and propellers cooperate with each other to enable the suspending sphere 6 to always move within a fixed range. When the suspending sphere 6 needs to be moved, the corresponding motor and propeller are controlled to make the suspending sphere 6 float in a directional manner.

[0044] Embodiment 2: A water quality monitoring platform is provided inside the control panel 501, and the water quality monitoring platform is communicatively connected to a water area model unit, a data acquisition unit, a parameter analysis unit, an abnormality feedback unit, a comprehensive evaluation unit and an early warning processing unit;

[0045] The water quality monitoring platform records and stores the real-time data collected by the detection device body 1 from the initial stage to the current stage;

[0046] The water area model unit stores the data from the time the water area is established to the current simulation time and constructs an online water area digital simulation model. It also obtains internal water quality parameter information and external environmental parameter information based on the water area model. The internal water quality parameter information includes pH value, dissolved oxygen, and turbidity, and the external environmental parameter information includes water temperature and flow rate. The internal water quality parameter information and the external environmental parameter information are sent to the data acquisition unit and the parameter analysis unit respectively.

[0047] After receiving the internal water quality parameter information, the data acquisition unit immediately performs abnormal fluctuation analysis and sends the obtained abnormal fluctuation coefficient ABi to the abnormal feedback unit;

[0048] After receiving the external environment parameter information, the parameter analysis unit immediately analyzes it and sends the obtained warning signal to the warning processing unit;

[0050] After receiving the abnormal risk coefficient YHFz, the comprehensive assessment unit simulates the water quality risk data (including water quality characteristic values ​​and water quality performance values) with the water area model data, and after analysis, sends the control signal and regulation signal to the early warning processing unit.

[0051] The specific operation process of the data acquisition unit is as follows: the start and end time of the water area model simulation is collected, marked as the time threshold, and the simulated pH value, dissolved oxygen, and turbidity within the time threshold are obtained. The internal water quality parameter assessment value is expressed as the interval value obtained by scaling the parameter fluctuation range and the fluctuation duration. The internal water quality parameter supervision value is expressed as the ratio of the number of times the parameter exceeds the preset range and the corresponding interval duration average, which is scaled by the interval, marked as NP and NJ respectively. According to the formula The abnormal fluctuation coefficient ABi is calculated to quantify the abnormal fluctuation of water quality parameters within a given time threshold.

[0052] Knp and kNJ are the correction factors of NP and NJ respectively, NP>NJ>0.

[0053] The specific operation process of the parameter analysis unit is as follows:

[0054] Acquire the simulated external environmental parameter values ​​(water temperature, flow rate) within the time threshold. The external environmental parameter value represents the interval value obtained by interval scaling when the parameter exceeds the preset threshold, including the water temperature risk value and the flow rate risk value. The water temperature risk value represents the interval value obtained by interval scaling of the duration that the water temperature characteristic curve exceeds the preset curve and the mean water temperature. The flow rate risk value represents the interval value obtained by interval scaling of the portion of the flow rate that exceeds the preset range and the mean flow rate.

[0055] Obtain the simulated sampling risk value within the time threshold. The sampling risk value represents the interval value obtained by scaling the difference range value of water samples sampled at different depths and the sampling time interval. Combined with the sampling error range value (the interval value obtained by scaling the time difference from sampling to detection), compare the external environmental parameter value and the sampling risk value with the preset threshold. If both are less than the preset threshold, no signal is generated. If both are greater than or equal to the preset threshold, an early warning signal is generated.

[0056] The specific operation process of the abnormal feedback unit is as follows:

[0057] Obtain the abnormal fluctuation coefficient ABi within the time threshold, retrieve the external environmental parameter value and sampling risk value, and the simulated water quality change value. The interval value obtained by scaling the average of the number of water quality index changes and the range of the degree of change is the proportion of the single change to the total change, marked as WBPz, CYFz and SZBz respectively. According to the formula YHFz=Q1*AB i +Q2*WBP z +Q3*CYF z +Q4*SZB z Calculate the abnormal risk coefficient YHFz, and Q1, Q2, Q3, and Q4 are the weight coefficients of ABi, WBPz, CYFz, and SZBz, respectively, and Q1>Q2>Q3>Q4>0.

[0058] The specific process of water quality risk assessment analysis in the comprehensive assessment unit is as follows:

[0059] Obtain the values ​​of the simulated water quality characteristic values ​​(pH, dissolved oxygen, and turbidity) that exceed the preset threshold within the time threshold, compare them with the preset threshold, and if they are greater than the threshold, mark the excess portion as the risk value FXz; obtain the values ​​of the water quality performance values ​​(water temperature and flow rate) that exceed the preset threshold, compare them with the preset threshold, and if they are greater than the threshold, mark the excess portion as the impact value YHz;

[0060] The water quality risk assessment coefficient SZPGi is calculated according to the formula SZPGi=M1*FXz+M2*YHz and compared with the preset threshold value YTSZPGi. If the ratio is ≥1, a control signal is generated. If the ratio is <1, a feedback instruction is generated. M1 and M2 are the weight coefficients of the risk value FXz and the impact value YHz respectively, and M1>M2>0.

[0061] When the comprehensive evaluation unit generates feedback instructions:

[0062] The water quality risk assessment coefficient SZPGi corresponding to the feedback signal and SZPGin of the previous n simulations are obtained as natural numbers. A curve is drawn with the number as the horizontal axis and SZPGi as the vertical axis. The ratio of the length of the ascending line segment to the descending line segment is calculated and marked as the water quality trend risk coefficient. It is compared with the preset threshold. If it is less than the threshold, no signal is generated. If it is greater than or equal to the threshold, a control signal is generated.

[0063] In combination with the first and second embodiments, it can be seen that a multi-channel sampling unit, a flow path switching unit, a detection unit, and a control unit are provided in the main body of the detection device. The multiple groups of water pumping pipes 201 of the multi-channel sampling unit can collect water samples at different depths in the water area. The suspension assembly and the suspension sphere 6 on the outside of the water pumping pipe 201 can achieve stable suspension of the water pumping pipe 201, ensuring the reliability of water sample collection at different depths. The multi-channel valve 301 of the flow path switching unit cooperates with the drive motor 302 to achieve flexible switching and collection of multi-channel water samples.

[0064] The multiple water quality parameter sensors of the detection unit can quickly measure the multi-parameter indicators of water samples and record and store real-time data. The water area model unit constructs an online digital simulation model of the water area and provides internal and external parameter information. The data acquisition unit, parameter analysis unit, etc. respectively analyze and calculate internal water quality parameters, external environmental parameters, etc. The abnormal feedback unit calculates the abnormal risk coefficient YHFz based on multiple types of parameters. The comprehensive evaluation unit calculates the water quality risk assessment coefficient SZPGi through water quality characteristic values ​​and water quality performance values ​​and generates corresponding signals. It can also draw curves based on historical SZPGi data to analyze the water quality trend risk coefficient, forming a complete process from data acquisition, model simulation to risk assessment and early warning processing, realizing rapid detection of multiple water quality parameters and comprehensive analysis and intelligent management of water quality risks.
