Description

Technical Field

[0001] The invention belongs to the technical field of numerical adjustment, and in particular relates to a numerical adjustment 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 of vital importance. The wharf pile foundation project includes offshore pile foundation and onshore pile foundation. The offshore pile foundation is ordinary bored pile, and the onshore pile foundation is high-strength steel pipe pile. The reinforcement project mainly includes the inspection, evaluation and reinforcement of the original pile foundation.

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

[0004] In addition, in order to ensure that the collected information values ​​of the wharf pile foundation construction have the overall attributes of the source information values, it is necessary to make them conform to the collection speed under the bandpass sampling law. However, due to the mixture of variability and regularity of the information values ​​of the wharf pile foundation construction, the collection speed determined by the variability will have a large number of information value repetitions in the space where there are not many changes in numerical attributes. This will reduce the frequency band required for the information values ​​to reach the controller, weakening the necessity of the collection operation. Summary of the invention

[0005] In order to solve the defects in the prior art, the present invention proposes a numerical adjustment system and method based on the wharf pile foundation construction, which effectively avoids the defects in the prior art that the acquisition speed recognized by drastic changes will have a high level of information value duplication in a space without many changes in numerical attributes, will not reduce the frequency band required for the information value to reach the controller, and weaken the necessity of the acquisition operation.

[0049] Figure 2It is a partial structural diagram of the numerical adjustment system based on the wharf pile foundation construction described in the present invention. DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely express the technical solution 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 making creative work are all within the protection scope of the present invention.

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

[0052] The pressure sensor and the inclination sensor respectively collect the pressure values ​​of the connection positions of each upper horizontal connecting pipe and the pole-shaped steel of the wharf pile foundation construction and the inclination values ​​of each vertical connecting pipe position of the wharf pile foundation construction and transmit them to the controller. The pressure values ​​of the connection positions of each upper horizontal connecting pipe and the pole-shaped steel of the wharf pile foundation construction or the inclination values ​​of each vertical connecting pipe position of the wharf pile foundation construction are the information values ​​of the wharf pile foundation construction; the controller determines the safety status of the hanging platform of the wharf pile foundation construction based on the information values ​​of the wharf pile foundation construction transmitted; the method for the controller to determine the safety status of the hanging platform of the wharf pile foundation construction based on the information values ​​of the wharf pile foundation construction transmitted can be: pre-setting 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 the wharf pile foundation construction also includes:

[0054] Step 1, obtaining an 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, and 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-restrictive embodiment of the present invention, in Step 1, the present application is to send the information values ​​of several types of wharf pile foundation construction to the controller after efficient adjustment, that is, the key of the present application is to improve the efficiency of sending information values ​​to the controller by improving the collection method. Therefore, before performing the collection and processing, the information values ​​of different types of wharf pile foundation construction must be obtained. The information values ​​of different types of wharf pile foundation construction include: different pressure values ​​of the connection positions of the upper horizontal connecting pipe and the shoulder pole steel or different inclination values ​​of the vertical connecting pipe positions. The queue formed by arranging the pressure values ​​of the connection positions of the upper horizontal connecting pipe and the shoulder pole steel or the inclination values ​​of the vertical connecting pipe positions in the order of their collection time is an information value queue of the wharf pile foundation construction. That is to say, a number of pressure sensors are respectively arranged at the connection positions of a number of upper horizontal connecting pipes and pole-shaped steels, and a number of inclination sensors are respectively arranged at the positions of a number of vertical connecting pipes. The pressure sensors and inclination sensors collect information values ​​according to their collection speeds. The information value queue formed by the pressure value at the connection position of an upper horizontal connecting pipe and pole-shaped steel or the information value queue formed by the inclination value at the position of a vertical connecting pipe is the 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 as the information value queue of the wharf pile foundation construction that collects the pressure value of the upper horizontal connecting pipe and the shoulder pole steel connection position, the information value queue of the wharf pile foundation construction that collects the pressure value of the upper horizontal connecting pipe and the shoulder pole steel connection position , collect the pressure value of the upper horizontal connecting pipe and the shoulder pole steel connection position 2 to obtain the information value queue of the wharf pile foundation construction of the pressure value of the upper horizontal connecting pipe and the shoulder pole steel connection position 2 , collect the inclination value of the vertical connecting pipe position 1 to obtain the information value queue of the wharf pile foundation construction of the inclination value of the vertical connecting pipe position 1 , collect the inclination value of the vertical connecting pipe position 2 to obtain the information value queue of the wharf pile foundation construction of the inclination value of the vertical connecting pipe position 2 , information value queue for wharf pile foundation construction , , , These are information value queues of four different types of wharf pile foundation construction. In one information value queue of wharf pile foundation construction, the information values ​​collected each time, such as the pressure value of the upper horizontal connecting pipe and the shoulder-pole steel connection position one, the pressure value of the upper horizontal connecting pipe and the shoulder-pole steel connection position two, the inclination value of the vertical connecting pipe position one, and the inclination value of the vertical connecting pipe position two, 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 Step 1, Wiener denoising can be performed on the information value group of the wharf pile foundation construction, which is to prevent interference values ​​from being detrimental to the accuracy of cyclic acquisition.

[0058] Step 2, identify the mutation space corresponding to the information value queue of the wharf pile foundation construction, the mutation space is the information value range with strong fluctuations in the information value queue of the wharf pile foundation construction;

[0059] The information value attributes of the wharf pile foundation construction are diverse, including timeliness, regularity, drastic change and abnormality. That is to say, timeliness reflects that the information value of the wharf pile foundation construction at some locations often increases or decreases with time changes; regularity reflects that the information value of the wharf pile foundation construction at some locations gradually increases or decreases with the change of the working stage; drastic change and abnormality reflect that the information value of the wharf pile foundation construction at some locations often has sudden changes. Such sudden changes, that is, sudden changes are often difficult to control through existing models, and the probability of appearance is very random, and the information value under such drastic changes has many numerical attributes.

[0060] The information values ​​of some wharf pile foundation construction projects that change frequently, such as the information values ​​of some wharf pile foundation construction projects in the short term, will have some drastic changes. The rapid change space of different types of information values ​​is also different. Therefore, the analysis here only faces one type, such as the pressure value at a certain position, and the analysis method of other types of information values ​​is the same.

[0061] If the change of information value of the wharf pile foundation construction at a certain location is very random, it will be disordered. Therefore, when collecting and processing it, the collection speed will be difficult to obtain due to the random change of the information value. To improve the collection mode and improve the efficiency of the information value delivery to the controller, it is necessary to first identify the numerical range or numerical range with approximate change attributes (the numerical value is the information value). The numerical range with approximate change attributes is similar or the same in the collection speed. When collecting and processing the information value, the randomness of the numerical attribute should not cause the defect of inappropriate collection speed; otherwise, the drastic information value with strong fluctuations should conform to the numerical fluctuation attribute in the collection speed before the collection mode can be improved. Therefore, it is necessary to identify the numerical sudden change space with strong fluctuations. In this application, the information value sudden change trend attribute corresponding to the information value queue of the wharf pile foundation construction is analyzed to obtain the sudden change space. It can be seen that the more similar the information value sudden change trend attribute of the information value in a certain range is, the more it can be regarded as the same sudden change space.

[0062] In a preferred but non-limiting embodiment of the present invention, Step 2 specifically comprises:

[0063] Step 2-1, calculating the sudden change trend attributes of the information values ​​corresponding to each moment in the information value queue of the wharf pile foundation construction;

[0064] Use the above information value queue for the construction of the wharf pile foundation , , , The explanation is carried out for an information value queue of any wharf pile foundation construction. Here, the information value queue of the corresponding wharf pile foundation construction at a location can be taken as an example. The information value queue of the wharf pile foundation construction includes the information value of the wharf pile foundation construction collected once per second. 60 seconds is regarded as a time interval, and the sudden change trend attributes of the information value corresponding to each moment in the information value queue of the wharf pile foundation construction are initially identified.

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

[0066] Calculating time according to the Cartesian system The moment adjacent to its predecessor The L2 norm between the time points is used in this application. The neighboring numerical points in the neighbor category (one numerical point is the coordinate point of one information value) are added to the calculation time The moment adjacent to its predecessor The L2 norm between The nearest value point in the nearest category is the moment Its previous neighbor Nearest neighbor value points and time Its adjacent neighboring value points, defined as , the time obtained by calculation The moment adjacent to its predecessor The L2 norm between is defined as:

[0067] ;

[0068] Here, Representative moments The X coordinate value on the Cartesian system, Representative moments The previous adjacent moment The X coordinate value on the Cartesian system, Representative moments The corresponding Y coordinate value on the Cartesian system is, Representative moments The corresponding Y coordinate value on the Cartesian system is, Representative joins the structure moment The moment adjacent to its predecessor The L2 norm of the nearest neighboring numerical points.

[0069] Just as, registering the present moment as the moment , based on the current time The information value of the wharf pile foundation construction is at the same time The change status and time of the information values ​​of the wharf pile foundation construction The information value of the wharf pile foundation construction is at the same time The change status of the information value of the wharf pile foundation construction is determined at the current time The information value of the wharf pile foundation construction corresponds to the criticality factor. The value can be determined according to specific needs.

[0070] In a preferred but non-limiting embodiment of the present invention, in Step 2-1, the current time is calculated using the following equation: The corresponding criticality factors of the information value of the wharf pile foundation construction are:

[0071] ;

[0072] Here, Representative moments The corresponding criticality factor of the information value of the wharf pile foundation construction is Representative moments The information value of the wharf pile foundation construction corresponds to the time The change in the information value of the wharf pile foundation construction, that is, the time The moment adjacent to its predecessor The L2 norm between Representative moments The information value of the wharf pile foundation construction corresponds to the time The change in the information value of the wharf pile foundation construction, that is, the time The moment adjacent to its predecessor The L2 norm between represent and The mean of Represents the Euler number.

[0073] The sudden change trend attribute of the information value corresponding to the current moment is determined based on the L2 norm between the current moment and the previous adjacent moment and the criticality factor corresponding to the information value of the wharf pile foundation construction at the current moment; the L2 norm is proportional to the sudden change trend attribute of the information value corresponding to the current moment. In a preferred but non-restrictive embodiment of the present invention, in Step 2-1, the sudden change trend attribute of the information value corresponding to the current moment is calculated using the following equation:

[0074] ;

[0075] Here, Representative moments The corresponding information value changes rapidly. Representative moments The corresponding criticality factor of the information value of the wharf pile foundation construction is Representative moments The X coordinate value on the Cartesian system, Representative moments The previous adjacent moment The X coordinate value on the Cartesian system, Representative moments The corresponding Y coordinate value on the Cartesian system is, Representative moments The corresponding Y coordinate value on the Cartesian system is, Representative joins the structure moment The moment adjacent to its predecessor The L2 norm of the nearest numerical point between them, Represents the use of Z-score method to Perform standardized disposal.

[0076] The above equation, Representative moments The moment adjacent to its predecessor The higher the L2 norm, the faster the time At the same time The higher the change in the information value of the wharf pile foundation construction, the greater the sudden change trend attribute of the corresponding information value. The derivation process under the condition of wharf pile foundation construction is: the information value of the wharf pile foundation construction at a certain position shows a sudden increase or decrease in a certain period, so in a constant time, the higher the L2 norm between the time start point and the time end point of the value point with a large change, which means that the more significant the change in the information value is, the closer it is to the sudden change value. During the collection period, the corresponding duration of such sudden change values ​​is not long (the duration of the sudden change state is not long compared with the reasonable state). Therefore, a relatively high collection speed is required to ensure that the source value attribute is not lost. Therefore, the continuous numerical range of such sudden change values ​​can be regarded as a sudden change space, and the change of a numerical point is not enough to represent the sudden change of the information value. Because the time interval is not large, several neighboring numerical points are selected here to add the L2 norm addition operation to identify the sudden change space. Therefore, the higher the amount obtained by the total addition, the greater the sudden change trend attribute of the corresponding information value.

[0077] In the above equation, the time is used The corresponding criticality factor of the information value of the wharf pile foundation construction About the moment Information value of wharf pile foundation construction When performing multiplication, the slower the change of the numerical point, the smaller the criticality in calculating the L2 norm, because the slower the change, the more balanced the increase or decrease of the numerical point, the more it is caused by the original properties of the source value, just as the change speed of liquid pressure varies, the information value of this type of value has a low rapid change trend property, so the corresponding criticality factor is smaller, the information value obtained by the operation has a rapid change trend property, and the execution principle of the equation is: and The closer we get, the more orderly the changes become. The closer it gets to one, The closer it is to one, the slower the overall change of the information value, and the lower the mean decrease, the smaller the criticality factor is, and the smaller the rapid change trend attribute of the obtained information value is.

[0078] In short, the sudden change trend attributes of the corresponding information values ​​at each moment can be calculated.

[0079] Step 2-2, take the moment when the attribute of the sudden change trend of the information value is within the pre-defined range as the space division point, and determine the sudden change space corresponding to the information value queue of the wharf pile foundation construction based on the space division point.

[0080] The closer the information value sudden change trend attribute is to 1, the greater the sudden change is. In a preferred but non-limiting embodiment of the present invention, in Step 2-2, the information value sudden change trend attribute is within a predefined range as shown in The moment is taken as the space division point, and the space division point is added to the space division to identify the sudden change space corresponding to the information value queue of the wharf pile foundation construction, and the remaining undivided space is taken as another space segment. That is, as long as there is a sudden change space, after the information value sudden change trend attribute calculation, the space segment belonging to the sudden change space must have a pair of time points that meet the sudden change, and the space formed by taking this pair of time points as the starting point and the end point is the overall sudden change space.

[0081] Step 3, determine the change status of each sudden change space in the wavelet coefficient, and determine the corresponding acquisition speed of the sudden change space according to the change status;

[0082] The values ​​of the abrupt space fluctuate greatly, and there is a lot of numerical attribute information. To maintain the information value attributes of the wharf pile foundation construction before collection, the abrupt space requires a higher collection speed when executing collection.

[0083] In a preferred but non-limiting embodiment of the present invention, Step 3 specifically comprises:

[0084] Step 3-1, perform wavelet transformation on the information value of the wharf pile foundation construction in adjacent time in the sudden change space to obtain the corresponding real part value of each time range in the sudden change space;

[0085] In order to accurately obtain the spatial information of the sudden change space, it is necessary to perform wavelet transform on the information value of the wharf pile foundation construction in the adjacent time in the sudden change space to obtain the real part value of each time range in the sudden change space.

[0086] That is to say, in a preferred but non-restrictive implementation of the present invention, in Step 3-1, wavelet transform is performed on the numerical range separated from a pair of adjacent moments in the abrupt change space to obtain its wavelet coefficient, which includes real value and imaginary value, so there are several real value and imaginary value here, just as, in the abrupt change space, there are one hundred moments, so there are ninety-nine numerical ranges, correspondingly there are ninety-nine real value and imaginary value, and the real value is obtained accordingly: ,here It represents the The real value of the wavelet transform of a time range is the time To time The category formed between is a natural number.

[0087] Step 3-2, according to the highest real part value, the lowest real part value, the total amount of time in the sudden change space, the sudden change trend attribute of the information value corresponding to each moment in the sudden change space, and the scattered amplitude calculation of the real part value in the sudden change space, the sudden change variable of the sudden change space is obtained, and the acquisition speed is obtained accordingly. The sudden change variable of the sudden change space represents the change status of the sudden change space in the wavelet coefficient;

[0088] In a preferred but non-limiting embodiment of the present invention, in Step 3-2, the abrupt change of the abrupt change space is obtained by using the following equation:

[0089] ;

[0090] Here, Represents abrupt change space The step variable, Represents abrupt change space The highest real value within the real value range of the inner time, Represents abrupt change space the lowest real value among the real values ​​of the inner time range, Represents abrupt change space The total amount of the inner time range, Represents abrupt change space Neidi The information value at a certain moment changes rapidly, Represents abrupt change space Neidi The real part of the time range, Represents abrupt change space The mean of the real part of the entire time range.

[0091] In the above equation, the sudden change variable in the sudden change space is to digitize the change of the information value of the wharf pile foundation construction in the sudden change space in the wavelet coefficient. The higher the difference in the real part value, that is, The higher it is, the more it means that the value change in the sudden change space is irregular, because the real part value reflects the frequency of the value, that is, the higher the wavelet coefficient attribute difference of the value, the less correlation there is at a certain point in time. Corresponding to the pile foundation construction environment of the wharf, just like the pressure value, the force and force direction exerted on the upper horizontal connecting pipe and the shoulder pole steel will change significantly in a short period of time, and the change is disordered. Therefore, such change information should be sent to the controller as an attribute value to achieve the function of timely controlling the matching change of the control motor under the pressure value change. Therefore, the higher the real part value change, the higher the sudden change in the sudden change space.

[0092] In the above equation, the accumulated value The dispersion amplitude representing the real value in the sudden change space is the discreteness of the real value to be digitized. The larger the dispersion amplitude, the stronger the change of the information value of the wharf pile foundation construction at different times, the greater the irrelevance, and the larger the corresponding sudden change, and the more it must be sent to the controller as an attribute value, so the corresponding acquisition speed must be increased. The above cumulative value expression is similar to the standard deviation operation expression, but here it is used as the critical value during the source variance operation, and the real value is multiplied by the corresponding sudden change trend attribute. At this moment, the greater the sudden change trend attribute of the information value, that is, the greater the criticality, the greater the value of the value when calculating the real value standard deviation, and the greater the corresponding sudden change.

[0093] In the abrupt change space, the higher the variation range of the real part of the wavelet coefficient, the greater the abrupt change of the wavelet coefficient in the time period. Because in the abrupt change space, the corresponding wavelet coefficients in different time periods differ greatly, which means that the information value (such as pressure value) of the wharf pile foundation construction has disordered changes, just as some information values ​​have significant changes in the short term. Therefore, in order to maintain this type of change attribute, the acquisition speed must be faster.

[0094] The sudden variable of the sudden change space is standardized; the corresponding acquisition speed 1 of the sudden change space is obtained according to the acquisition speed 2 of the standardized sudden variable; the acquisition speed 1 of the sudden change space is proportional to the sudden variable of the sudden change space.

[0095] In a preferred but non-limiting embodiment of the present invention, in Step 3-2, the following equation is used to obtain the corresponding acquisition speed of the abrupt space:

[0096] ;

[0097] Here, Represents abrupt change space The corresponding acquisition speed is Represents abrupt change space The step variable, Represents the use of Z-score method to Implement standardized disposal, Represents acquisition speed 2, here Represents abrupt change space The mean of the real part of the entire time range.

[0098] Faced with the collection speed of one, represents the acquisition speed 2, which is the source acquisition speed that complies with the bandpass sampling law, represents the acquisition speed value that complies with the bandpass sampling law under the mean of the real value, and the sudden change space The larger the sudden change, the greater the corresponding collection speed, which can ensure that the information value maintains its numerical properties after collection.

[0099] In short, each abruptly changing space has an acquisition speed of one, and when facing non-abruptly changing space, its acquisition speed only needs to conform to the bandpass sampling law.

[0100] Step 4, take the acquisition speed 1 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 2 as the acquisition speed of the sensor belonging to the information value queue of the wharf pile foundation construction without abrupt change space. Here, the acquisition speed 2 is the source acquisition speed of the bandpass sampling law.

[0101] That is to say, the controller is used to control and the collection speed one is regarded as the collection speed of the sensor belonging to the information value queue of the wharf pile foundation construction with a sudden change space, and the collection speed two is regarded as the collection speed of the sensor belonging to the information value queue of the wharf pile foundation construction without a sudden change space. The sensor belonging to the information value queue of the wharf pile foundation construction is the sensor through which the information value in the information value queue of the wharf pile foundation construction is collected.

[0102] By performing data collection using the above method, each value range has a collection speed obtained based on the value attributes. The collection speed reduces the total amount of information values ​​while ensuring the source value attributes, weakens the frequency band required for the information values ​​to be delivered to the controller, and increases the efficiency of the information values ​​of the wharf pile foundation construction being delivered to the controller.

[0103] like Figure 2 As shown, the numerical adjustment system based on the wharf pile foundation construction described in the present invention includes:

[0104] The pressure sensor and the inclination sensor connected to the controller are used to respectively collect the pressure values ​​of the connection positions of each upper horizontal connecting pipe and the pole-shaped steel of the wharf pile foundation construction and the inclination values ​​of each vertical connecting pipe position of the wharf pile foundation construction and transmit them to the controller.

[0105] The modules running on the controller include:

[0106] A queue module is used to obtain an 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] A recognition module, which is used to recognize 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 sudden change space in the wavelet coefficient, and to identify the corresponding acquisition speed of the sudden change space according to the change status;

[0109] The speed module is used to regard the acquisition speed 1 as the acquisition speed of the sensor to which the information value queue of the wharf pile foundation construction with abrupt change space belongs, and regard the acquisition speed 2 as the acquisition speed of the sensor to which the information value queue of the wharf pile foundation construction without abrupt change space belongs. The controller can be a PLC, a single-chip microcomputer or an industrial 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 sudden change space corresponding to the information value queue of the wharf pile foundation construction, the collection speed one corresponding to the sudden change space is identified according to the change of the sudden change space in the wavelet coefficient, and the collection speed one is regarded as the collection speed of the sensor belonging to the information value queue of the wharf pile foundation construction with the sudden change space, the collection mode can be made closer to the source value attribute, the total amount of information value is reduced, the frequency band required for the information value to be delivered to the controller is weakened, and the efficiency of the information value of the wharf pile foundation construction to be delivered to the controller is increased.
