Description

Technical Field

[0001] The present invention belongs to the technical field of numerical regulation, and particularly relates to a numerical regulation system and method based on wharf pile foundation construction. Background Art

[0002] As one of the basic projects of wharf construction, the construction of wharf pile foundation is crucial. The wharf pile foundation project includes offshore pile foundation and onshore pile foundation. The offshore pile foundation is a common bored cast-in-place pile, and the onshore pile foundation is a high-strength steel pipe pile. The reinforcement project mainly includes the detection, evaluation and reinforcement treatment of the original pile foundation.

[0003] In terms of the execution control of wharf pile foundation construction, as mentioned in the prior art solution with the patent publication number "CN217480073U", it includes a pressure sensor and an inclination sensor connected to a controller. The pressure sensor and the inclination sensor are used to collect the pressure values at the connection positions of each upper horizontal connecting pipe and the shoulder steel in wharf pile foundation construction and the inclination values at the positions of each vertical connecting pipe in wharf pile foundation construction respectively and transmit them to the controller. The pressure value at the connection position of each upper horizontal connecting pipe and the shoulder steel in wharf pile foundation construction or the inclination value at the position of each vertical connecting pipe in wharf pile foundation construction is the information value of wharf pile foundation construction; the controller is used to determine the safety status of the hanging platform in wharf pile foundation construction according to the transmitted information value of wharf pile foundation construction.

[0004] In addition, to ensure that the information value of wharf pile foundation construction collected has the overall attributes of the source information value, it is necessary to make it meet the acquisition speed under the band-pass sampling theorem. However, due to the mixture of rapid change and regularity of the information value of wharf pile foundation construction, the acquisition speed determined by rapid change has a relatively high information value repetition in the space without many numerical attribute changes, so that the frequency band required for the information value to reach the controller will not be reduced, weakening the necessity of the acquisition operation. Summary of the Invention

[0005] To solve the defects in the prior art, the present invention proposes a numerical regulation system and method based on wharf pile foundation construction, effectively avoiding the defects in the prior art that the acquisition speed determined by rapid change has a relatively high information value repetition in the space without many numerical attribute changes, will not reduce the frequency band required for the information value to reach the controller, and weakens the necessity of the acquisition operation.

[0006] The present invention adopts the following technical solutions.

[0007] A numerical regulation method based on wharf pile foundation construction includes:

Calculate the L2 norm between the obtained moment and its immediately preceding moment and define it as:

[0028] Furthermore, in Step2-2, the moment when the rapid change trend attribute of the information value is within the pre-defined range is used as the space segmentation point, and the space segmentation point is added to the space segmentation to identify the rapid change space corresponding to the information value queue of the wharf pile foundation construction.

[0029] Furthermore, Step3 specifically includes:

[0030] Step3-1, perform wavelet transform on the information value of the wharf pile foundation construction in the adjacent moments within the rapid change space to obtain the real part values corresponding to each moment range within the rapid change space;

[0031] Step3-2, calculate the sudden change amount of the rapid change space based on the highest real part value, the lowest real part value, the total number of moments within the rapid change space, the rapid change trend attribute of the information value corresponding to each moment within the rapid change space, and the dispersion amplitude of the real part values within the rapid change space, and thereby obtain the acquisition speed one.

Brief Description of the Drawings

[0048] Figure 1 is the flowchart of the numerical adjustment method based on wharf pile foundation construction described in the present invention;

[0049] Figure 2It is a partial structure diagram of the numerical adjustment system based on wharf pile foundation construction described in the present invention. Detailed implementation mode

[0050] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described in this application are only partial embodiments of the present invention, not all embodiments. According to the spirit of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] As Figure 1 shown, a numerical adjustment method based on wharf pile foundation construction described in the present invention includes:

[0052] A pressure sensor and an inclination sensor respectively collect the pressure values at the connection positions of each upper horizontal connecting pipe and the cross-shaped steel of the wharf pile foundation construction and the inclination values at the positions of each vertical connecting pipe of the wharf pile foundation construction and transmit them to the controller. The pressure value at the connection position of each upper horizontal connecting pipe and the cross-shaped steel of the wharf pile foundation construction or the inclination value at the position of each vertical connecting pipe of the wharf pile foundation construction is the information value of the wharf pile foundation construction; the controller determines the safety status of the hanging platform of the wharf pile foundation construction according to the transmitted information value of the wharf pile foundation construction; the method for the controller to determine the safety status of the hanging platform of the wharf pile foundation construction according to the transmitted information value of the wharf pile foundation construction can be: preset the upper limit value of the pressure value and the upper limit value of the inclination value. If the pressure value or the inclination value in the information value of the wharf pile foundation construction does not exceed the upper limit value of the pressure value or the upper limit value of the inclination value respectively, it is determined that the hanging platform of the wharf pile foundation construction is in a safe state, otherwise the hanging platform of the wharf pile foundation construction is in an unsafe state.

[0053] The numerical adjustment method based on wharf pile foundation construction further includes:

[0054] Step1, obtain the information value group of the wharf pile foundation construction. The information value group of the wharf pile foundation construction includes several information value queues of the wharf pile foundation construction. One information value queue of the wharf pile foundation construction represents one type of information value of the wharf pile foundation construction;

[0055] In a preferred but non-limiting embodiment of the present invention, in Step 1, the present application is to efficiently adjust the information values of several types of wharf pile foundation construction and then send them to the controller. That is, the key of the present application is to improve the acquisition method to achieve the effect of improving the efficiency of sending information values to the controller. Therefore, before performing the acquisition and processing, the information values of different types of wharf pile foundation construction need to be obtained. The information values of different types of wharf pile foundation construction include: the pressure values at the connection positions of different upper horizontal connecting pipes and the shoulder steel bars, or the inclination values at the positions of different vertical connecting pipes. A queue formed by arranging the pressure value at the connection position of one upper horizontal connecting pipe and the shoulder steel bar or the inclination value at the position of one vertical connecting pipe in the order of their acquisition times is an information value queue of a wharf pile foundation construction. That is to say, several pressure sensors are respectively arranged at the connection positions of several upper horizontal connecting pipes and the shoulder steel bars, and several inclination sensors are respectively arranged at the positions of several vertical connecting pipes. The pressure sensors and the inclination sensors collect information values according to their acquisition speeds. An information value queue formed by the pressure value at the connection position of one upper horizontal connecting pipe and the shoulder steel bar or an information value queue formed by the inclination value at the position of one vertical connecting pipe is an information value of a type of wharf pile foundation construction. The information value queue is a vector, and the elements in the queue are the elements of the vector.

[0056] Just like the information value queue of the wharf pile foundation construction that obtains the pressure value at the connection position of the upper horizontal connecting pipe and the shoulder steel bar 1 by collecting the pressure value at the connection position of the upper horizontal connecting pipe and the shoulder steel bar 1 , the information value queue of the wharf pile foundation construction that obtains the pressure value at the connection position of the upper horizontal connecting pipe and the shoulder steel bar 2 by collecting the pressure value at the connection position of the upper horizontal connecting pipe and the shoulder steel bar 2 , the information value queue of the wharf pile foundation construction that obtains the inclination value at the position of the vertical connecting pipe 1 by collecting the inclination value at the position of the vertical connecting pipe 1 , the information value queue of the wharf pile foundation construction that obtains the inclination value at the position of the vertical connecting pipe 2 by collecting the inclination value at the position of the vertical connecting pipe 2 , the information value queue of the wharf pile foundation construction 、 、 、 are four information value queues of different types of wharf pile foundation construction. In an information value queue of a wharf pile foundation construction, the information values collected each time, such as the pressure value at the connection position of the upper horizontal connecting pipe and the shoulder steel bar 1, the pressure value at the connection position of the upper horizontal connecting pipe and the shoulder steel bar 2, the inclination value at the position of the vertical connecting pipe 1, and the inclination value at the position of the vertical connecting pipe 2, are the information values of the corresponding types of wharf pile foundation construction respectively.

[0057] In a preferred but non-limiting embodiment of the present invention, in Step1, Wiener noise reduction can be performed on the information value group of the wharf pile foundation construction to prevent the interference value from being unfavorable to the accuracy of cyclic acquisition.

[0058] Step2, identify the mutation space corresponding to the information value queue of the wharf pile foundation construction. The mutation space is the category of information values with strong fluctuations within the information value queue of the wharf pile foundation construction;

[0059] The information value attributes of the wharf pile foundation construction are diverse, including timing, regularity, sudden change, and abnormality. That is to say, the timing reflects that the information values of the wharf pile foundation construction at some positions often show an increase or decrease in timing with the change of time length; the regularity reflects that the information values of the wharf pile foundation construction at some positions gradually increase or decrease with the change of the working stage; the sudden change and abnormality reflect that the information values of the wharf pile foundation construction at some positions often have sudden changes. Such sudden changes, that is, rapid changes, are often difficult to control by existing models, and the appearance probability is very random, and the information values under such sudden changes have many numerical attributes.

[0060] Some information values of the wharf pile foundation construction with frequent changes, such as some information values of the wharf pile foundation construction in the short term, will have some sudden changes. The rapid change spaces of different types of information values are also different. Therefore, the analysis here only faces one type, such as the pressure value at a certain position, and the analysis methods for other types of information values are the same.

[0061] If the change of the information value of the wharf pile foundation construction at a certain position is very random, it has some disorder. Therefore, when performing acquisition and processing on it, the acquisition speed will also be difficult to obtain due to the random change of the information value. To improve the acquisition mode and the efficiency of delivering the information value to the controller, first, it is necessary to identify the numerical range or numerical range (the numerical value is the information value) with similar change attributes. The numerical range with similar change attributes is similar or the same in terms of acquisition speed. When performing acquisition and processing on this information value, the defect that the acquisition speed is inappropriate due to the randomness of the numerical attributes should not occur; otherwise, for the sudden change information value with strong fluctuations, the acquisition speed should conform to the numerical fluctuation attribute in order to improve the acquisition mode. Therefore, it is necessary to identify the numerical rapid change space with strong fluctuations. In this application, analyze the information value rapid change trend attribute corresponding to the information value queue of the wharf pile foundation construction to obtain the rapid change space. It can be known that the more similar the information value rapid change trend attribute of the information value in a certain range is, the more it can be regarded as the same rapid change space.

[0062] In a preferred but non-limiting embodiment of the present invention, Step2 specifically includes:

[0063] Step2-1, calculate the information value rapid change trend attribute corresponding to each moment in the information value queue of the wharf pile foundation construction;

[0064] Use the information value queue of the above wharf pile foundation construction , , , For any information value queue of wharf pile foundation construction, an elaboration is performed here. Here, it can be the information value queue of wharf pile foundation construction at a corresponding position. The information value queue of wharf pile foundation construction contains the information values of wharf pile foundation construction collected once every 1 s. Taking 60 s as a time interval, initially determine the sharp change trend attribute of the corresponding information values at each moment in the information value queue of wharf pile foundation construction.

[0065] In a preferred but non-limiting embodiment of the present invention, in Step 2-1, construct the Cartesian system of the corresponding time - information value of the wharf pile foundation construction. Here, the information values of the corresponding type of wharf pile foundation construction are collected in a way of collecting once every 1 s, so as to obtain the information value queue of the corresponding type of wharf pile foundation construction. Define 60 s as a moment. When constructing the Cartesian system, use each moment of a time interval (the time interval can be the span size of the collection moments of the information value queue (that is, the time interval between the moment of the first information value and the moment of the last information value)) as the X coordinate of the Cartesian system, and the information value of the wharf pile foundation construction corresponding to each moment as the Y coordinate of the Cartesian system, that is, only register the information values of the wharf pile foundation construction collected in a time interval of 60 s; that is, use each collection moment as the X coordinate, and the information value of the wharf pile foundation construction collected at each collection moment as the Y coordinate, that is, register the information values of the wharf pile foundation construction collected at each collection moment. The moment in this application is the collection moment.

[0066] Calculate the moment according to the Cartesian system and its immediately preceding moment the L2 norm between them. In this application, use the nearest neighbor numerical points (1 numerical point is the coordinate point of 1 information value) in the nearest neighbor range of the moment to participate in calculating the L2 norm between the moment and its immediately preceding moment . The nearest neighbor numerical points in the nearest neighbor range of the moment are the number of its immediately preceding nearest neighbor numerical points and the moment number of its immediately following nearest neighbor numerical points, defined as . The calculated L2 norm between the moment and its immediately preceding moment is defined as:[[]]

[0067] ;

[0068] ​Here, represents the moment X coordinate value on the Cartesian system, represents the moment of the immediately preceding moment X coordinate value on the Cartesian system, represents the moment corresponding Y coordinate value on the Cartesian system, represents the moment corresponding Y coordinate value on the Cartesian system, represents the moment of joining the structure with its immediately preceding moment the neighboring numerical point of the L2 norm.

[0069] Just like, registering the current moment as the moment , according to the current moment information value of the wharf pile foundation construction and the moment information value of the wharf pile foundation construction, the change situation between the moments information value of the wharf pile foundation construction and the moment information value of the wharf pile foundation construction, determining the current moment key factor corresponding to the information value of the wharf pile foundation construction. The value can be determined according to specific requirements.

[0070] In a preferred but non-limiting embodiment of the present invention, in Step2-1, the following equation is used to calculate the key factor corresponding to the information value of the wharf pile foundation construction at the current moment :

[0071] ;

[0072] Here, represents the key factor corresponding to the information value of the wharf pile foundation construction at the moment , represents the information value of the wharf pile foundation construction at the moment corresponding to the information value of the wharf pile foundation construction at the moment the change amount, that is, the L2 norm between the moment and its immediately preceding moment , represents the information value of the wharf pile foundation construction at the moment corresponding to the information value of the wharf pile foundation construction at the moment the change amount, that is, the L2 norm between the moment and its immediately preceding moment , represents and The mean value of represents the Euler number.

[0073] Determine the rapid change trend attribute of the information value corresponding to the current time according to the key factor corresponding to the L2 norm between the current time and the adjacent previous time and the information value of the wharf pile foundation construction at the current time; the L2 norm is proportional to the rapid change trend attribute of the information value corresponding to the current time. In the preferred but non-limiting embodiment of the present invention, in Step2-1, the following equation is used to calculate the rapid change trend attribute of the information value corresponding to the current time:

[0074] ;

[0075] Here, represents the rapid change trend attribute of the information value corresponding to the time , represents the key factor corresponding to the information value of the wharf pile foundation construction at the time , represents the X coordinate value of the time in the Cartesian coordinate system, represents the time of the adjacent previous time in the Cartesian coordinate system, represents the time corresponding Y coordinate value in the Cartesian coordinate system, represents the time corresponding Y coordinate value in the Cartesian coordinate system, represents the adjacent numerical point of the L2 norm between the added construction time and its adjacent previous time , represents the use of the Z-score method for to perform standardization processing.

[0076] For the above equation, represents the L2 norm between the time and its adjacent previous time . The higher this norm, the time and the time The greater the change in the information value during the wharf pile foundation construction between them, the greater the corresponding sharp change trend attribute of the information value. The derivation process corresponding to the wharf pile foundation construction conditions is as follows: The information value of the wharf pile foundation construction at a certain position shows a sudden increase or decrease during a certain period. Then, within a constant time length, the higher the L2 norm between the start time and the end time among the time points with such non-small changes, which means the more significant the change in the information value, the closer it is to the sharp change value. During the acquisition period, the duration corresponding to such sharp change values is not large (the duration of the sharp change situation is not large compared to the reasonable situation). Therefore, a relatively high acquisition speed is required to ensure that the source value attributes are not missed. Therefore, the numerical range corresponding to the duration of such sharp change values can be regarded as a sharp change space, and the change of a single numerical point is not enough to represent the sharp change of the information value. Because the time interval is not large, several adjacent numerical points are selected here and added to the L2 norm operation to determine the sharp change space. It can be seen that the higher the sum obtained, the greater the corresponding sharp change trend attribute of the information value.

[0077] In the above equation, the key factor corresponding to the information value of the wharf pile foundation construction at time is multiplied by the information value of the wharf pile foundation construction at time The slower the change of the numerical point, the smaller the key factor in calculating the L2 norm. Because the slower the change, the more balanced the increase or decrease of the numerical point, which is more caused by the original attributes of the source value. Just like the uneven change of liquid pressure, etc. The sharp change trend attribute of the information value of such numerical values is not high. Therefore, the corresponding key factor is smaller, and the sharp change trend attribute of the information value obtained by the operation. The execution criterion of the equation is: The closer it is to and the more orderly the change, the closer it is to one. Then is closer to one, and the overall change of the information value is slower, the average reduction is lower. At this time, the key factor is smaller, and the sharp change trend attribute of the information value obtained is smaller.

[0078] In short, the sharp change trend attribute of the information value corresponding to each moment can be calculated.

[0079] Step2-2: Take the moments when the sharp change trend attribute of the information value is within a predefined range as space segmentation points, and determine the corresponding sharp change space of the information value queue of the wharf pile foundation construction according to the space segmentation points.

[0080] The closer the sharp change trend attribute of the information value is to one, the greater the sudden change. In the preferred but non-limiting implementation manner of the present invention, in Step2-2, the sharp change trend attribute of the information value is within a predefined range, just like Take the moment as the space segmentation point, add the space segmentation point to the space segmentation, and thus identify the corresponding rapidly changing space of the information value queue of the wharf pile foundation construction. The remaining unsegmented space is regarded as another space segment. That is, as long as there is a rapidly changing space, after being operated on by the information value rapid change trend attribute, the space segment belonging to the rapidly changing space must have a pair of time points that conform to the rapid change property, and the space formed by taking this pair of time points as the starting point and the end point respectively is the overall rapidly changing space.

[0081] Step3, identify the change situation of each rapidly changing space in the wavelet coefficients, and determine the corresponding acquisition speed one of the rapidly changing space according to the change situation;

[0082] The numerical fluctuations of the rapidly changing space are very strong, and there is a lot of numerical attribute information. To maintain the information value attribute of the wharf pile foundation construction before acquisition, a higher acquisition speed is required for the rapidly changing space during acquisition.

[0083] In the preferred but non-limiting embodiment of the present invention, Step3 specifically includes:

[0084] Step3-1, perform wavelet transform on the information values of the wharf pile foundation construction at adjacent times in the rapidly changing space to obtain the real part values corresponding to each time range in the rapidly changing space;

[0085] To accurately obtain the space information of the rapidly changing space, it is necessary to perform wavelet transform on the information values of the wharf pile foundation construction at adjacent times in the rapidly changing space to obtain the real part values of each time range in the rapidly changing space.

[0086] That is to say, in the preferred but non-limiting embodiment of the present invention, in Step3-1, perform wavelet transform on the numerical range segmented by a pair of adjacent times in the rapidly changing space to obtain its wavelet coefficients. The wavelet coefficients include real part values and imaginary part values. Therefore, there are several real part values and imaginary part values here. For example, in this rapidly changing space, there are one hundred times, so there are ninety-nine numerical ranges, and correspondingly ninety-nine real part values and imaginary part values. Based on this, the real part values are obtained: , where represents the th real part value of the wavelet transform of the time range, and this time range is the range formed between time and time , is a natural number.

[0087] Step3-2, calculate the rapid change amount of the rapidly changing space according to the highest real part value, the lowest real part value, the total number of times in the rapidly changing space, the information value rapid change trend attribute corresponding to each time in the rapidly changing space, and the dispersion amplitude of the real part values in the rapidly changing space, and thus obtain the acquisition speed one. The rapid change amount of the rapidly changing space represents the change situation of the rapidly changing space in the wavelet coefficients;

[0088] In a preferred but non-limiting embodiment of the present invention, in Step 3-2, the following equation operation is used to obtain the sudden change amount of the rapid change space:

[0089] ;

[0090] Here, represents the sudden change amount of the rapid change space , represents the highest real part value within the real part values of the time range in the rapid change space , represents the lowest real part value among the real part values of the time range in the rapid change space , represents the total amount of the time range in the rapid change space , represents the sudden change trend attribute of the information value at the th moment in the rapid change space , represents the real part value of the th time range in the rapid change space , represents the average of the real part values of all time ranges in the rapid change space .

[0091] In the above equation, the sudden change amount of the rapid change space is to digitalize the change situation of the information value of the wharf pile foundation construction in the rapid change space within the wavelet coefficients. The higher the difference in real part values, that is the higher, the more it means that the numerical change in the rapid change space is irregular. Because the level of the real part value reflects the level of the frequency of the numerical value, that is, the higher the difference in the wavelet coefficient attributes of the numerical value, the less relevant it is within the time point. Corresponding to the wharf pile foundation construction environment, just like the pressure value, in the short term, the acting force and the acting force direction on the upper horizontal connecting pipe and the shoulder steel beam change significantly and disorderly. Therefore, this type of change information should be regarded as an attribute value and sent to the controller to achieve the effect of timely controlling the change of the motor matching under the change of the pressure value. Therefore, the higher the change amount of the real part value, the higher the sudden change amount of the rapid change space.

[0092] In the above equation, the cumulative value The dispersion amplitude representing the real part value in the rapid change space is the discreteness of the real part value to be digitized. The greater the dispersion amplitude, the stronger the variation of the information value of the wharf pile foundation construction at different times, the greater the irrelevance, so the corresponding sudden change amount is greater, and the more it needs to be sent to the controller as an attribute value. Therefore, it is necessary to increase its corresponding acquisition speed. The above cumulative value expression is similar to the operation expression of the standard deviation, and here it is regarded as the key value during the operation of the source variance. Multiply the real part value by the corresponding rapid change trend attribute. The greater the rapid change trend attribute of the information value at this moment, that is, the greater the key value, it is considered that the value of this numerical value in calculating the standard deviation of the real part value is greater, and the corresponding sudden change amount is greater.

[0093] In the rapid change space, the higher the variation range of the real part value of the wavelet coefficient, the greater the sudden change amount of the time period of the wavelet coefficient. Because in this rapid change space, the difference in the wavelet coefficients corresponding to different time periods is not small, it means that the information value (such as the pressure value) of the wharf pile foundation construction has disordered changes. Just like some information values have large changes in a short period, so at this time, to maintain this type of change attribute, the acquisition speed needs to be greater.

[0094] Standardize the sudden change amount of the rapid change space; obtain the corresponding acquisition speed one of the rapid change space according to the standardized sudden change amount and the acquisition speed two; the corresponding acquisition speed one of the rapid change space is proportional to the sudden change amount of the rapid change space.

[0095] In the preferred but non-limiting embodiment of the present invention, in Step3-2, the following equation is used to obtain the corresponding acquisition speed one of the rapid change space:

[0096] ;

[0097] Here, represents the corresponding acquisition speed one of the rapid change space , represents the sudden change amount of the rapid change space ; represents the standardized processing of using the Z-score method, represents the acquisition speed two. Here represents the average value of the real part values in the entire time range within the rapid change space .

[0098] Facing the acquisition speed one, and represents the acquisition speed two. The acquisition speed two is the source acquisition speed that conforms to the bandpass sampling law, representing the acquisition speed value that conforms to the bandpass sampling law under the average value of the real part value. The greater the sudden change amount of the rapid change space , the greater the corresponding acquisition speed one, and the more it can ensure that the information value maintains its numerical attributes after being acquired.

[0099] In summary, each rapid change space has a collection speed 1. For the non-rapid change space, its collection speed just needs to conform to the bandpass sampling law.

[0100] Step4, regard the collection speed 1 as the collection speed of the sensor belonging to the information value queue of the wharf pile foundation construction with rapid change space, and regard the collection speed 2 as the collection speed of the sensor belonging to the information value queue of the wharf pile foundation construction without rapid change space. Here, the collection speed 2 is the source collection speed of the bandpass sampling law.

[0101] That is to say, use the controller to control and regard the collection speed 1 as the collection speed of the sensor belonging to the information value queue of the wharf pile foundation construction with rapid change space, and regard the collection speed 2 as the collection speed of the sensor belonging to the information value queue of the wharf pile foundation construction without rapid change space. The sensor belonging to the information value queue of the wharf pile foundation construction is the information value in the information value queue of the wharf pile foundation construction collected by this sensor.

[0102] Through the above method for collection, each numerical range has a collection speed obtained according to the numerical attribute. The collection speed reduces the total amount of information values under the condition of ensuring the source numerical attribute, weakens the frequency band required for the information values to reach the controller, and increases the efficiency of the information values of the wharf pile foundation construction reaching the controller.

[0105] The modules running on the controller include:

[0106] A queue module, which is used to obtain the information value group of the wharf pile foundation construction. The information value group of the wharf pile foundation construction includes several information value queues of the wharf pile foundation construction. One information value queue of the wharf pile foundation construction represents one type of information value of the wharf pile foundation construction;

[0107] An identification module, which is used to identify the mutation space corresponding to the information value queue of the wharf pile foundation construction;

[0108] A change module, which is used to identify the change status of each abrupt change space in the wavelet coefficients, and determine the corresponding acquisition speed one of the abrupt change space according to the change status;

[0109] A speed module, which is used to take the acquisition speed one as the acquisition speed of the sensor belonging to the information value queue of the wharf pile foundation construction with abrupt change space, and take the acquisition speed two as the acquisition speed of the sensor belonging to the information value queue of the wharf pile foundation construction without abrupt change space. The controller can be a PLC, a single-chip microcomputer or an industrial control computer.

[0110] The beneficial effects of the present invention are that, compared with the prior art, the technical effects of the present invention include:

[0111] By identifying the abrupt change space corresponding to the information value queue of the wharf pile foundation construction, determining the corresponding acquisition speed one of the abrupt change space according to the change status of the abrupt change space in the wavelet coefficients, and taking the acquisition speed one as the acquisition speed of the sensor belonging to the information value queue of the wharf pile foundation construction with abrupt change space, the acquisition mode can be closer to the source numerical attributes, reduce the total amount of information values, weaken the frequency band required for the information values to reach the controller, and improve the efficiency of the information values of the wharf pile foundation construction reaching the controller.
