Description

Technical Field

[0001] The present invention belongs to the technical field of hydraulic pressure measurement, and specifically relates to a hydraulic pressure measurement device and method for an ecological floating island. Background Art

[0002] Ecological floating island, also known as artificial floating bed, ecological floating bed, etc. It is a kind of artificial floating island. It uses the principle of ecological engineering to degrade COD, nitrogen and phosphorus in water for eutrophic water quality. It takes aquatic plants as the main body, applies the principle of soilless cultivation technology, uses polymer materials as carriers and matrices, applies the symbiotic relationship between species, and makes full use of the spatial niche and nutritional niche of the water body, so as to construct an efficient artificial ecosystem to reduce the pollution load in the water body. It can greatly improve the transparency of the water body, and at the same time, the water quality indicators are also effectively improved, especially it has a good inhibitory effect on algae. The most important effect of ecological floating island on water purification is to use the root system of plants to absorb eutrophic substances in the water, such as total phosphorus, ammonia nitrogen, organic matter, etc., so that the nutrients of the water body are transferred, and the water body odor and eutrophication caused by the closure or lack of self-circulation are reduced.

[0003] In practical applications, facing ecological floating islands, the patent announcement number "CN204824367U" is often used.

[0004] The hydraulic sensor mentioned in the prior art solution of "measures the hydraulic pressure value generated by the water body on the ecological floating island body and transmits it to the controller, and the controller performs processing and analysis on the transmitted hydraulic pressure value (the processing and analysis can be to send the hydraulic pressure value to a display screen connected to the controller for display, or to combine the hydraulic pressure value with the liquid level height value of the pool body of the ecological floating island body measured by the liquid level sensor connected to the controller to obtain the optimal position information of the ecological floating island body).

[0005] However, during the period when the hydraulic sensor measures the hydraulic pressure value generated by the water body on the ecological floating island body, the hydraulic pressure value obtained will have some disturbance fluctuations due to the aging of the hydraulic sensor itself and the influence of external factors during the measurement period; secondly, because there will be a number of successive water surges that will have an impact on the ecological floating island body, and different water surges will have some differences in the impact of the corresponding hydraulic sensor measurement point, the resulting linkage hydraulic force will also be somewhat different, causing the hydraulic pressure value at the measurement point to have some disturbance fluctuations; so such abnormal disturbance fluctuations, coupled with the ecological The fluctuation of hydraulic pressure value caused by the failure (the failure may be the damage or disintegration of ecological floating island units) of the ecological floating island body (several ecological floating island units are connected in series from left to right to form the ecological floating island body) objectively requires the sorting of the real abnormal disturbance floating values, while the floating hydraulic pressure value caused by the failure of the ecological floating island unit itself should be kept for processing and analysis. However, there is currently a lack of methods for sorting out the real abnormal disturbance floating values ​​in the hydraulic pressure values ​​generated by the water body on the ecological floating island body, and for processing and analysis, the floating hydraulic pressure value caused by the failure of the ecological floating island unit itself should be kept for processing and analysis. Summary of the invention

[0058] The beneficial effects of the present invention are that, compared with the prior art, the technical effects of the present invention include:

[0059] By analyzing each individual value (partial hydraulic value) of the hydraulic sensor within the set time period, the partial abnormal amplitude of each partial hydraulic value is confirmed. This method avoids the disturbance caused by the slope waveform change characteristics of the hydraulic value, the aging of the hydraulic sensor itself and the external factors during the measurement period on the abnormal hydraulic value confirmation of the ecological floating island unit, thereby improving the accuracy of numerical collation; at the same time, by analyzing the comprehensive numerical change rules of the hydraulic value measured by the hydraulic sensor in time series, and analyzing the regular differences between it and other surrounding hydraulic sensors, the overall numerical orderliness of the hydraulic sensor itself and the probability of being affected by the ecological floating island unit are confirmed. This method avoids the misidentification of the abnormal hydraulic value of the ecological floating island unit by the disturbance floating caused during the water surge, thereby improving the accuracy of subsequent numerical collation. By combining the abnormal amplitude of single-unit values ​​and the failure probability of the ecological floating island unit, and taking into account the impact of the failure of the ecological floating island unit itself and the abnormal disturbance of other factors, it is possible to centrally determine whether the hydraulic values ​​of each part are hydraulic values ​​that have suffered abnormal disturbance floating. Such hydraulic values ​​cannot reasonably identify and analyze the failure caused by the ecological floating island unit itself, so as to focus on screening or correcting such hydraulic values ​​with abnormal disturbances and improve the accuracy of hydraulic value processing and analysis. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Figure 1 It is a flow chart of the hydraulic pressure value measurement method for the ecological floating island described in the present invention;

[0061] Figure 2 It is a partial structural diagram of the hydraulic pressure value measuring device for the ecological floating island described in the present invention. DETAILED DESCRIPTION

[0062] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely expressed in conjunction with the drawings in the embodiments of the present invention. The embodiments expressed in this application are only partial embodiments of the present invention, not all embodiments. According to the spirit of the present invention, other embodiments obtained by technicians in this field without creative work are all within the protection scope of the present invention.

[0063] like Figure 1 As shown, the hydraulic pressure value measurement method for an ecological floating island according to the present invention comprises:

[0064] The hydraulic sensor measures the hydraulic pressure value generated by the water body on the ecological floating island body and transmits it to the controller. After the controller sorts the transmitted hydraulic pressure value, it uses the sorted hydraulic pressure value to perform processing and analysis (the processing and analysis can be to send the hydraulic pressure value to a display screen connected to the controller for display, or to combine the hydraulic pressure value with the liquid level height value of the pool of the ecological floating island body measured by the liquid level sensor connected to the controller to obtain the optimal position information of the ecological floating island body);

[0065] The method for the controller to sort out the transmitted hydraulic pressure value includes:

[0066] Step 1: According to the set time period values ​​of the hydraulic sensor, determine the abnormal amplitude of the single value of the hydraulic sensor and the amplitude difference between the adjacent single values;

[0067] Several hydraulic sensors are respectively arranged on several ecological floating island units of the ecological floating island body (the number of hydraulic sensors is the same as that of ecological floating island units, and several ecological floating island units are connected in series from left to right to form the ecological floating island body), which are used to measure the hydraulic value of each unit of the ecological floating island body in real time.

[0068] In a preferred but non-limiting embodiment of the present invention, in Step 1, the time segment values ​​are set to divide all hydraulic values ​​according to the set time segment size, thereby analyzing the values ​​of each time segment to confirm the abnormal conditions of the ecological floating island unit in each time segment value.

[0069] The time periods can be set according to requirements, such as ten seconds. For the several ecological floating island units of the ecological floating island body to be measured, the sequence codes can be compiled for each hydraulic sensor in sequence according to the arrangement sequence of the ecological floating island units from left to right. Each hydraulic sensor synchronously (synchronization means the same time point of measurement for each hydraulic sensor) continuously measures the hydraulic value of the water body encountered by the corresponding ecological floating island unit for ten seconds (that is, the time period value is set, and the time period value is the hydraulic value measured for ten seconds at a time) and transmits it to the controller for analysis. The present invention uses any hydraulic sensor to perform analysis.

[0070] Because the abnormal disturbance floating values ​​(abnormal disturbance floating) formed by the aging of the hydraulic sensor itself and the influence of external factors during the measurement are often manifested as partial value fluctuations, which will cause disordered sudden changes in the hydraulic value. For the hydraulic value of the conventional ecological floating island unit, it is often manifested as a continuous slope waveform. The amplitude of the slope waveform is relatively standardized, that is, the amplitudes of several adjacent upper protrusions (the upper protrusion is the waveform point in the slope waveform with a higher amplitude than the waveform points adjacent to it on both sides) or lower protrusions (the lower protrusion is the waveform point in the slope waveform with a lower amplitude than the waveform points adjacent to it on both sides) are almost the same, or are increased or decreased without sudden changes.

[0071] Therefore, by confirming the abnormal amplitude of each single value (a single value is a numerical point measured by the hydraulic sensor, and this numerical point is a hydraulic value) in a set time period, the disturbance amplitude of the hydraulic value caused by the hydraulic sensor can be confirmed. The abnormal amplitude of the single value here can reflect the disordered amplitude or protrusion amplitude of each single value compared with other single values ​​around it.

[0072] For the obtained set time period value, its monomer value has amplitude and protrusion point, so the amplitude difference between adjacent monomer values ​​can also be obtained from it, and the protrusion point is an upward protrusion value (the monomer values ​​in the set time period value are arranged according to the order of their measurement time points. If a monomer value is larger than the two adjacent monomer values ​​on both sides, the monomer value is an upward protrusion value) or a downward protrusion value (the monomer values ​​in the set time period value are arranged according to the order of their measurement time points. If a monomer value is smaller than the two adjacent monomer values ​​on both sides, the monomer value is a downward protrusion value). The amplitude of the present invention is the value of the corresponding hydraulic value.

[0073] In a preferred but non-limiting embodiment of the present invention, Step 1 specifically includes:

[0074] Step 1-1: According to the set time segment value of the hydraulic sensor, a protrusion cluster formed by a random protrusion point and a number of corresponding protrusion points adjacent to it is identified;

[0075] Step 1-2: Determine the target amplitude difference between the target protrusion point and other protrusion points in the protrusion cluster;

[0076] Step 1-3: Use the target amplitude difference and the limit amplitude difference within the protrusion cluster to determine the hydraulic transmission

[0077] The single value of the hydraulic sensor is the hydraulic value obtained by measuring the single value of the hydraulic sensor.

[0078] In a preferred but non-limiting embodiment of the present invention, Step 1-3 specifically includes:

[0079] The target amplitude difference is regarded as the partial protrusion amplitude of the monomer value corresponding to the target protrusion point;

[0080] The abnormal amplitude of the single value of the hydraulic sensor is calculated by using the partial protrusion amplitude, the target amplitude corresponding to the target protrusion point and the limit amplitude difference within the protrusion cluster.

[0081] According to the continuous change relationship of the measured set time period values ​​in time series, there is often a small difference between adjacent hydraulic pressure values, so the random measurement time point The corresponding protrusion point is used as the target protrusion point (here, the protrusion point can also be used represent, Corresponding to the measurement time point, When the point protrusion has a single property), on one side or the other side or both sides, a number of corresponding adjacent protrusions are obtained, just as the number of adjacent corresponding protrusions is taken. (If the protrusion is an upward protrusion value, then the other protrusion points are also upward protrusion values, otherwise they are all downward protrusion values). Based on this, the corresponding adjacent protrusion points are combined to construct a value cluster (a value cluster is also a protrusion cluster).

[0082] In a preferred but non-limiting embodiment of the present invention, in Step 1-2, the target amplitude difference between the target protrusion point and other protrusion points in the protrusion cluster is determined. , which is to obtain the target amplitude of the numerical point corresponding to the target protrusion point (The target amplitude is the value of the hydraulic pressure represented by the target protrusion point), and the difference between the target amplitude corresponding to the target protrusion point and the amplitude corresponding to another protrusion point in the value cluster (the amplitude is the value of the hydraulic pressure represented by the other protrusion point) is obtained. The calculation equation is:

[0083]

[0084] In the equation, Indicates the hydraulic sensor to be tested now. represents another salient point in the value cluster, Represents the target amplitude corresponding to the target protrusion point, Represents the corresponding amplitude of other protrusion points; The amplitude of some protrusions reflected in the timing, The higher the value of, the higher the partial protrusion amplitude, and the corresponding A protrusion point (also known as a protrusion point ) has a higher magnitude of abnormality.

[0085] In a preferred but non-limiting embodiment of the present invention, in Step 1-3, the target amplitude difference and the limit amplitude difference within the protrusion cluster are used to identify the abnormal amplitude of the single value of the hydraulic sensor, that is, for the first The higher the value of a protruding point in the value cluster, the higher the probability of its abnormality. Therefore, to obtain the abnormal amplitude of the single value of the target protruding point at any time point (the time point is the measurement time point), the calculation equation is:

[0086]

[0087]

[0088] In the equation, The abnormal amplitude of the single value of the hydraulic sensor when the peak point in the cluster is an upward peak value. The abnormal amplitude of the single value of the hydraulic sensor under the condition that the peak point in the value cluster is the downsurge value, Represents the maximum difference in the value cluster currently being processed (the maximum difference in value is the difference in limit amplitude, which is the absolute value of the amount obtained by subtracting the highest amplitude from the lowest amplitude in the value cluster). represent The corresponding highs and lows in the cluster of values, The higher the value of The higher the abnormal amplitude of the protrusion point, the higher the abnormal amplitude of the protrusion point. The weight is assigned, and the abnormal amplitude of the single value of any protrusion point is obtained, that is, the abnormal amplitude of the single value of the hydraulic sensor; when the protrusion point is a down-surge value, the abnormal amplitude of the single value of the hydraulic sensor is calculated by Representative, here Represents the minimum difference in the values ​​in the cluster (the minimum difference in the values ​​is the difference in the limit amplitude, and the minimum difference in the values ​​is the one with the lowest absolute value after subtracting each amplitude in the cluster). The higher, the The higher the abnormal amplitude of each protrusion point.

[0089] In a preferred but non-limiting embodiment of the present invention, Step 1 specifically further comprises:

[0090] Step 1-4: According to the set time period value of the hydraulic sensor, determine the amplitude difference between the adjacent up-rush values ​​of each group;

[0091] Step 1-5: According to the set time period value, determine the amplitude difference between the adjacent down-burst values ​​of each group;

[0092] Here, two adjacent up-jump values ​​or two adjacent down-jump values ​​are considered as a group. Amplitude difference 1 and amplitude difference 2 are the amplitude differences between adjacent single values.

[0093] According to experience, the hydraulic pressure value is often transmitted to both sides along the ecological floating island body in the direction of water flow, and the hydraulic pressure value gradually weakens with the increase of the distance. When an abnormal hydraulic effect is caused by the failure of an ecological floating island unit located in the ecological floating island body (the failure may be the damage or disintegration of the ecological floating island unit), the hydraulic pressure values ​​measured by some hydraulic sensors on the right side of the ecological floating island unit along the direction of hydraulic transmission and the hydraulic pressure values ​​measured by the hydraulic sensors on the left side of the ecological floating island unit will damage the original hydraulic pressure weakening rules. Therefore, the ecological floating island unit where the hydraulic sensor with abnormal hydraulic effect is located can be identified based on the difference in hydraulic pressure values ​​between adjacent hydraulic sensors.

[0094] The propagation of the hydraulic pressure value formed by the hydraulic action within the ecological floating island body also takes some time, and the transmission rate of the hydraulic pressure within the ecological floating island body is related to the material properties of the ecological floating island body. In order to avoid the deviation of the hydraulic pressure value measured by the hydraulic sensor caused by factors such as the propagation time, the hydraulic pressure propagation rate and the distance between two adjacent hydraulic sensors can be obtained based on previous experiments on the ecological floating island body; therefore, the propagation time between two adjacent hydraulic sensors can be obtained by dividing the distance by the rate.

[0095] During the period of water surge, as the water surge approaches, the hydraulic values ​​measured by each hydraulic sensor are in a period of gradual expansion, that is, their values ​​(amplitudes) are in a period of gradual increase.

[0096] Therefore, in the present invention, the hydraulic pressure sensor can be obtained The amplitude difference between all adjacent up-surge values ​​or adjacent down-surge values ​​in the corresponding set time period , the amplitude difference It is the absolute value of the quantity obtained by subtracting the two adjacent upward values ​​(amplitude difference one) or the absolute value of the quantity obtained by subtracting the two adjacent downward values ​​(amplitude difference two). It represents the corresponding measurement time point of any upward or downward surge value, and similarly it can also represent the surge point.

[0097] At this time, according to the above method, the water body is in the surging period, so for the hydraulic sensor, the shorter the distance between the surging water body, the closer the synchronous measurement time point is to the current measurement time point, then the amplitude difference between a group of adjacent up-surge values ​​should be in a period of continuous increase.

[0098] Then according to the updated position at the measurement time, that is The higher the value, the closer the measurement time is, and the closer it is to the current measurement time. Based on this, the amplitude difference between the up-surge points of the two adjacent groups is obtained. and The reduction between and The amount obtained by subtracting each other), where a group is every two adjacent upward values ​​or every two adjacent downward values. In terms of upward values, the amplitude difference between the adjacent upward values ​​of each group is the absolute value of the amount obtained by subtracting the corresponding amplitudes of the two adjacent upward values ​​of each group, that is, the amplitude reduction of each group. Similarly, the amplitude difference is the absolute value of the amount obtained by subtracting the corresponding amplitudes of the two adjacent downward values ​​of each group. The amplitude difference and The decrement between the two adjacent groups is obtained by subtracting the amplitude decrements of the two adjacent groups, which is the decrement one and decrement two mentioned below.

[0099] Step 2: According to the amplitude difference, determine the global order characteristic coefficient of the hydraulic sensor;

[0100] In a preferred but non-limiting embodiment of the present invention, Step 2 specifically includes:

[0101] Using the amplitude difference 1, determine the decrease of the amplitude difference 1 between adjacent groups;

[0102] Using the amplitude difference 2, determine the decrease in the amplitude difference 2 between adjacent groups;

[0103] Use reduction one and reduction two respectively to identify the corresponding amplitude change orderliness one and amplitude change orderliness two;

[0104] Determine the mean of the amplitude differences corresponding to all the amplitude differences 1 and 2;

[0105] The global order characteristic coefficient of the hydraulic sensor is calculated using the amplitude difference mean, amplitude change orderliness 1 and amplitude change orderliness 2.

[0106] That is, polling all the up-surge point groups, based on which the amplitude change of the hydraulic pressure value measured by the hydraulic sensor is orderly presented. , its operation equation is:

[0107]

[0108] In the equation, represents the number of all adjacent groups; by obtaining the decrement (decrement -) of the amplitude difference (amplitude difference -1) between all adjacent up-valued points (adjacent groups) Total measurement , and the absolute value of the total amount , according to which the expression Representative, that is , The value range is between; The closer it is to one, the more obvious the characteristic of the orderly increasing amplitude of the hydraulic pressure value measured in the hydraulic sensor due to the surge of the water body is, which means the orderliness of the hydraulic pressure value is stronger;

[0109] Similarly, according to the above method, the orderliness of the corresponding amplitude changes of all the down-sudden value point groups is obtained. .

[0110] Amplitude difference mean : By comparing the amplitudes of all groups of adjacent up-surge values ​​and adjacent down-surge values, the average amplitude difference of the hydraulic sensor is obtained. , Used to characterize the amplitude characteristics of the current sensor during measurement and compare it with other hydraulic sensors.

[0111] Combine the amplitude difference mean of the above calculations and get the hydraulic sensor The global order characteristic coefficient :

[0112]

[0113] In the equation, obtain the ordered mean corresponding to the up-surge value and the down-surge value , The higher and closer to one, the stronger the orderliness, and the smaller the probability of failure of the ecological floating island unit. Assign weights to the mean of amplitude differences, and we get ; Characterizes the overall ordered amplitude of the hydraulic pressure values ​​measured by the hydraulic pressure sensor.

[0114] At this time, when the ecological floating island unit is not invalid, the hydraulic pressure will weaken along with the weakening of the ecological floating island unit, and the amplitude will be slightly weakened compared with the surrounding sensors;

[0115] So for this A hydraulic sensor can obtain the corresponding hydraulic values ​​of the same number of hydraulic sensors on the left and right sides of the water body; based on the diffusion time obtained above, the hydraulic value of each ecological floating island unit corresponding to the hydraulic value formed by the same hydraulic force can be obtained, which can avoid occasional deviations.

[0116] Step 3: Use the global order characteristic coefficients of several adjacent hydraulic sensors to determine the failure probability of the ecological floating island unit of the hydraulic sensor;

[0117] By analyzing the global order characteristic coefficients of several adjacent hydraulic sensors including the hydraulic sensor, the failure probability of the ecological floating island unit where the hydraulic sensor is located can be analyzed more globally. The higher the failure probability, the more likely the abnormal value is to be caused by the failure of the ecological floating island unit itself.

[0118] In a preferred but non-limiting embodiment of the present invention, Step 3 specifically includes:

[0119] Step 3-1: Identify the difference in the global order characteristic coefficient between the hydraulic sensor and its left neighbor hydraulic sensor;

[0120] Step 3-2: Identify the difference between the global order characteristic coefficients of the hydraulic sensor and several adjacent hydraulic sensors on its right;

[0121] Step 3-3: Identify the difference in global order characteristic coefficients between several adjacent hydraulic sensors to the left of the left adjacent hydraulic sensor;

[0122] Step 3-4: Use difference one, difference two and difference three to calculate the failure probability of the ecological floating island unit of the hydraulic sensor.

[0123] Step 3-4 specifically includes:

[0124] Using the total measurements of difference one, difference two, and difference three, the failure probability of the ecological floating island unit of the hydraulic sensor is calculated.

[0125] According to the above method, the amplitudes between adjacent hydraulic sensors will be weakened with order, and when a certain ecological floating island unit fails, the above order will be damaged. If the hydraulic values ​​of adjacent hydraulic sensors are directly operated on variance, they will often suffer from the deviation caused by the small-scale amplification of the hydraulic force when it spreads in the ecological floating island body; therefore, the analysis is performed based on the global order characteristic coefficient of the above operation.

[0126] According to the analysis, when the failure part of the existing failed ecological floating island unit (the failure part is the specific part of the ecological floating island unit that is damaged or disintegrated) is located at the The hydraulic sensor on the left When the hydraulic sensor (the left adjacent hydraulic sensor) is connected, because it destroys the original hydraulic value characteristics, the difference in the above global order characteristic coefficient is higher; and because the hydraulic transmission characteristics of the ecological floating island itself have not changed at all, the first The right side of the hydraulic sensor The hydraulic values ​​on the left side of the sensor all continue the hydraulic characteristics of the adjacent hydraulic sensors on the left, and the differences in their corresponding global order characteristic coefficients are smaller. The higher the chance of failure.

[0127] Based on this, the hydraulic sensor currently being processed is obtained Probability of failure of ecological floating island unit The operational equation is:

[0128]

[0129] In the equation, Representatives of hydraulic sensors currently being processed and the hydraulic sensor adjacent to it on the left The difference between the global order characteristic coefficients (difference 1) The absolute value of the floating island unit is higher. The higher the value, the higher the probability of failure of the ecological floating island unit.

[0130] At this time, for the hydraulic sensor currently being processed The right side contains Including A hydraulic sensor is used to obtain the The characteristic factor between two adjacent hydraulic sensors among the hydraulic sensors and The difference , the difference is the difference of the global order characteristic coefficient between adjacent hydraulic sensors, based on which (difference 2 The cumulative amount ), Representing the A random hydraulic sensor among the hydraulic sensors; similarly, obtain the sensor The left side contains the hydraulic sensor Including A hydraulic sensor is used to obtain the Characteristic factor between two adjacent hydraulic sensors within a hydraulic sensor and The difference , the difference is the difference of the global order characteristic coefficients between several adjacent hydraulic sensors, based on which (difference three The cumulative amount ), Representing the Any hydraulic sensor in the sensor; the smaller the difference 2 and difference 3 are, the more it satisfies the conventional hydraulic transmission rules, and the more effective the failure rate of the above operation is; so the difference 2 and difference 3 are summed, and the sum value obtained by the summation is given a weight to the difference 1 of the above operation; based on this, , The higher the value, the more hydraulic sensors are being processed. The higher the chance of failure, The higher the value, the higher the abnormal amplitude of hydraulic pressure fluctuation caused by the failure of ecological floating island unit. The smaller the probability of the measured hydraulic pressure value being abnormal due to other factors, and the smaller the necessity of executing sorting.

[0131] Step 4: Use the abnormal amplitude of the single value and the failure probability of the ecological floating island unit to determine whether the single value is the value to be sorted, and perform sorting on the value to be sorted.

[0133] Determine the ratio between the magnitude of the single-unit numerical anomaly and the probability of failure of the ecological floating island unit;

[0135] Based on the above calculation, the abnormal amplitude of the single value of any hydraulic sensor and , and based on the calculated hydraulic sensor The probability of failure in the set time period; therefore, the partial abnormal amplitude can be corrected according to the probability of failure of the whole, so as to obtain the correction necessity and correction amplitude of the numerical point (that is, the single numerical value) at any measurement time point, and thus obtain the correction necessity and correction amplitude , the ratio of proofreading necessity to proofreading extent is the standardized ratio:

[0136] .

[0137] In the equation, is through the Z-sore method Execute standardization, Through the Z-sore method By performing standardization, the negative correlation between the abnormal amplitude of the single value and the failure probability of the ecological floating island unit makes the expression in the form of division, which can be regarded as assigning weight to the abnormal amplitude of the single value.

[0138] The ratio between the amplitude of the single value anomaly and the probability of failure of the ecological floating island unit and , while The corresponding inrush point is the uprush value (that is, ) is ,exist The corresponding inrush point is the downsurge value (that is, ) is ; Through the Z-sore method and Implement standardization and obtain ;above and The higher the value, the greater the abnormal amplitude of the single value, and the overall hydraulic value of the hydraulic sensor has not been affected by the failed ecological floating island unit, and the probability of the hydraulic value floating to an anti-constant value is not low.

[0139] A predefined threshold can be set according to specific requirements, just as a predefined threshold can be ,exist , it means that the abnormal disturbance of the single value is not low, then it will be sorted out, otherwise no change will be made to the single value.

[0140] In a preferred but non-limiting embodiment of the present invention, Step 4 specifically further comprises:

[0141] Using the standardized ratio, the value to be adjusted is calibrated to obtain the adjusted hydraulic value.

[0142] According to the above method, the values ​​to be sorted (hydraulic values ​​with a large abnormal disturbance amplitude) are sorted, and the sorted and calibrated hydraulic values ​​are used as new reference values ​​for processing and analysis. Based on this, the measurement time point of any hydraulic sensor after sorting is obtained. Corresponding partial hydraulic values:

[0143]

[0144] Here Represents the measurement time point Correspondingly, the values ​​to be collated are all the hydraulic values ​​measured by all the hydraulic sensors polled, and all the value collation is completed according to the above method.

[0145] like Figure 2 As shown, the hydraulic pressure value measuring device for an ecological floating island according to the present invention comprises:

[0146] A plurality of hydraulic sensors connected to the controller, the plurality of hydraulic sensors are respectively arranged on a plurality of ecological floating island units of the ecological floating island body (the number of hydraulic sensors is the same as that of ecological floating island units, and the plurality of ecological floating island units are connected in series from left to right to form the ecological floating island body), the hydraulic sensors are used to measure the hydraulic pressure value generated by the water body on the ecological floating island body and transmit it to the controller, the controller sorts out the transmitted hydraulic pressure value, and then uses the sorted hydraulic pressure value to perform processing and analysis (the processing and analysis may be to send the hydraulic pressure value to a display screen connected to the controller for display, or to combine the hydraulic pressure value with the liquid level height value of the pool of the ecological floating island body measured by the liquid level sensor connected to the controller to obtain the best position information of the ecological floating island body);

[0147] Modules running on the controller include:

[0148] Identification module 1, which is used to identify the abnormal amplitude of a single value of the hydraulic sensor and the amplitude difference between adjacent single values ​​according to the set time period values ​​of the hydraulic sensor;

[0149] Identification module 2, which is used to identify the global order characteristic coefficient of the hydraulic sensor based on the amplitude difference;

[0150] Identification module three, which is used to use the global order characteristic coefficients of several adjacent hydraulic sensors to identify the failure probability of the ecological floating island unit of the hydraulic sensor;

[0151] Identification module four is used to use the abnormal amplitude of the single value and the failure probability of the ecological floating island unit to determine whether the single value is the value to be sorted, and to perform sorting on the value to be sorted.

[0152] The beneficial effects of the present invention are that, compared with the prior art, the technical effects of the present invention include:

[0153] By analyzing each individual value (partial hydraulic value) of the hydraulic sensor within the set time period, the partial abnormal amplitude of each partial hydraulic value is confirmed. This method avoids the disturbance caused by the slope waveform change characteristics of the hydraulic value, the aging of the hydraulic sensor itself and the external factors during the measurement period on the abnormal hydraulic value confirmation of the ecological floating island unit, thereby improving the accuracy of numerical collation; at the same time, by analyzing the comprehensive numerical change rules of the hydraulic value measured by the hydraulic sensor in time series, and analyzing the regular differences between it and other surrounding hydraulic sensors, the overall numerical orderliness of the hydraulic sensor itself and the probability of being affected by the ecological floating island unit are confirmed. This method avoids the misidentification of the abnormal hydraulic value of the ecological floating island unit by the disturbance floating caused during the water surge, thereby improving the accuracy of subsequent numerical collation. By combining the abnormal amplitude of single-unit values ​​and the failure probability of the ecological floating island unit, and taking into account the impact of the failure of the ecological floating island unit itself and the abnormal disturbance of other factors, it is possible to centrally determine whether the hydraulic values ​​of each part are hydraulic values ​​that have suffered abnormal disturbance floating. Such hydraulic values ​​cannot reasonably identify and analyze the failure caused by the ecological floating island unit itself, so as to focus on screening or correcting such hydraulic values ​​with abnormal disturbances and improve the accuracy of hydraulic value processing and analysis.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not deviate from the spirit and scope of the present invention should be covered within the protection space of the claims of the present invention.
