Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, in the present embodiment, for better understanding of the method for dividing the open type TBM construction data tunneling cycle in the present application, the method includes:
a1, in the open type TBM operation, after each TBM tunneling cycle, acquiring parameter data in one TBM tunneling cycle through an intelligent data acquisition system of the TBM.
In this embodiment, the TBM tunneling cycle parameter data includes: and the cutter torque data, the cutter rotating speed data and the total thrust data in the TBM tunneling cycle.
A2, dividing the TBM tunneling cycle based on the parameter data of the TBM tunneling cycle, and determining the ascending section in the TBM tunneling cycle.
Referring to fig. 2, in the present embodiment, step a2 includes: and dividing the TBM tunneling cycle based on the parameter data of the TBM tunneling cycle, and determining an idle push section, an ascending section, a stable section and a shutdown section which are sequentially adjacent to each other in the tunneling cycle.
A3, acquiring parameter data corresponding to the ascending segment in the TBM tunneling cycle based on the ascending segment in the TBM tunneling cycle and the parameter data of the TBM tunneling cycle;
and A4, predicting geological parameters in the TBM tunneling cycle by adopting a preset prediction algorithm according to parameter data corresponding to the ascending section in the TBM tunneling cycle to obtain a prediction result.
In a specific application of this embodiment, the method specifically includes:
a2-1, determining the starting point of the idle section and the end point of the shutdown section in the TBM tunneling cycle based on the cutterhead rotating speed data in the TBM tunneling cycle.
Wherein, the starting point of the hollow pushing section in the TBM tunneling cycle is as follows: and the time point when the cutterhead torque is greater than 0 and the cutterhead rotating speed in the TBM tunneling cycle is changed from a value of 0 to a value other than 0.
The end point of the stop section in the TBM tunneling cycle is as follows: and the time point when the cutterhead torque is greater than 0 and the cutterhead rotating speed in the TBM tunneling cycle is suddenly changed from a value which is not 0 to a value which is 0.
That is to say, when the cutterhead torque is greater than 0 and the rotating speed of the open type TBM cutterhead is suddenly changed from 0rpm/min to a value other than 0, the time point is taken as the starting point of a tunneling cycle and is also taken as the starting point of a hollow pushing section in the tunneling cycle, and if the cutterhead torque is greater than 0 and the rotating speed of the cutterhead is suddenly changed from the value other than 0 to 0rpm/min, the time point is taken as the end point of a stopping section in the whole tunneling cycle.
A2-2, determining a first time point serving as a starting point of an ascending segment and an ending point of an idle driving segment in the TBM tunneling cycle based on the cutterhead rotating speed data in the TBM tunneling cycle.
A2-3, and determining a second time point of the TBM in the tunneling cycle as the starting point of the stop section and the end point of the stable section based on the total propelling force data and the cutterhead torque data in the tunneling cycle of the TBM.
A2-4, determining a third time point of the TBM serving as the starting point of the stable section and the ending point of the ascending section in the tunneling cycle based on the starting point of the idling section and the ending point of the stopping section in the tunneling cycle, a first time point of the TBM serving as the starting point of the ascending section and the ending point of the idling section in the tunneling cycle, a second time point of the TBM serving as the starting point of the stopping section and the ending point of the stable section in the tunneling cycle, and parameter data of the TBM tunneling cycle.
A2-5, determining the ascending section of the TBM in the tunneling cycle based on the first time point of the TBM in the tunneling cycle as the starting point and the ending point of the idle pushing section and the third time point of the TBM in the tunneling cycle as the starting point and the ending point of the stable section.
In this embodiment, the step a2-2 includes:
a2-2-1, acquiring the maximum value of the cutter head torque data in the TBM tunneling cycle and the maximum value of the first part of the cutter head torque data; and smoothing the cutter torque data in the TBM tunneling cycle to obtain the cutter torque smooth data in the TBM tunneling cycle.
And the first part of cutterhead torque data is the cutterhead torque data of the first third of the TBM tunneling cycle.
A2-2-2, judging whether the maximum value in the first part of cutter head torque data is smaller than 0.35 time of the maximum value of the cutter head torque data in the TBM tunneling cycle, and obtaining a judgment result.
A2-2-3, determining a first time point serving as a starting point of an ascending segment and an end point of an idle driving segment in the TBM tunneling cycle according to the first part of cutterhead torque data or the cutterhead torque data in the TBM tunneling cycle according to the judgment result.
In this embodiment, the step a2-2-3 includes:
and if the judgment result is that the maximum value in the first part of cutterhead torque data is less than 0.35 times of the maximum value of the cutterhead torque data in the TBM tunneling cycle, determining a first time point serving as a starting point of an ascending section and an end point of an idle pushing section according to the first part of cutterhead torque data and cutterhead torque smooth data.
And if the judgment result is that the maximum value in the first part of cutterhead torque data is 0.35 times larger than the maximum value of the cutterhead torque data in the TBM tunneling cycle, determining a first time point serving as a starting point of an ascending section and an end point of an idle pushing section according to the cutterhead torque data and cutterhead torque smooth data in the TBM tunneling cycle.
In practical application of the embodiment, in order to save calculation cost, the data of the front 1/3 of the cutterhead torque data in the TBM tunneling cycle is taken out in advance, and a minimum value is searched. And loading the minimum value points into a minimum value point list.
If the maximum value of the front cutter head torque 1/3 data is less than 0.35 times the maximum value of the cutter head torque data in the TBM tunneling cycle, the rising section starting point may be located at the rear 2/3 of the cutter head torque data in the TBM tunneling cycle, in this case, the rising section starting point does not exist in the minimum value point list of the front cutter head torque 1/3 data section, so that the search range of the minimum value point is expanded to the cutter head torque data in the whole TBM tunneling cycle, and the minimum value point in the cutter head torque data in the whole TBM tunneling cycle is loaded into the minimum value point list.
In practical application of the present embodiment, in the present embodiment, since the cutter head torque data in the TBM tunneling cycle is not smooth enough, as shown in fig. 3, it is relatively difficult to determine whether the data is stably rising, so that the trend of extracting data from the cutter head torque data in the TBM tunneling cycle, that is, the cutter head torque smooth data in the TBM tunneling cycle, as shown in fig. 4, is relatively simple to determine that the data is stably rising.
Since the first values and the last values of the cutter head torque smoothing data (ct _ trend) are NaN after the cutter head torque data in the TBM tunneling cycle are smoothed, value padding is performed. Because the torque of the cutter head in the idle pushing section of an individual TBM tunneling cycle can reach a very high value, even the maximum value of the whole TBM tunneling cycle, the cutter head slowly and stably climbs to the stable section after sudden drop, if 0 filling is adopted and the first non-0 point happens to correspond to a very large value in the idle pushing section, the sudden rise can cause the corresponding minimum value point to be mistakenly judged as the starting point of the ascending section. This is called false positive because generally the NaN in the smoothed data is relatively small, during which the onset of the rise is generally unlikely. If the NaN area really exists at the start of the ascending section, the start of the ascending section can be quickly determined due to the existence of the very large values in the null-push section, and the error caused by the very large values is also small. In order to solve the problem of the sudden rise caused by the 0 filling, in the embodiment, all NaN are marked by-1 (to avoid confusion with the 0 value in the non-NaN data segment, the-1 is selected because the data is all non-negative), and then all the-1 point values are filled by the first non-1 point value, so that the problem of the NaN value filling is well solved.
In this embodiment, determining a first time point as a start point of an ascending segment and an end point of an idle run segment according to the cutter head torque data and the cutter head torque smoothing data of the first portion specifically includes:
and acquiring a minimum value point in the cutter head torque data of the first part according to the cutter head torque data of the first part.
And judging whether the minimum value point meets a preset first condition or not.
If so, determining the time point corresponding to the minimum value point as a first time point of the starting point of the ascending segment and the ending point of the idle push segment.
Wherein the first condition is: and first cutter head torque smooth data are contained in the cutter head torque smooth data after the time point corresponding to the minimum value point.
The cutter head torque smooth data between the time point corresponding to the first cutter head torque smooth data and the time point corresponding to the minimum value point is monotonously not reduced or the reduction amplitude of the cutter head torque smooth data in each period between the time point corresponding to the first cutter head torque smooth data and the time point corresponding to the minimum value point is less than 0.35 time of the increase amplitude; and second cutter head torque smooth data is also provided after the time point corresponding to the first cutter head torque smooth data.
Wherein the period is: and the time period between the time points corresponding to the minimum value points in the adjacent cutterhead torque data.
And the difference value between the first cutter disc torque smooth data and the second cutter disc torque smooth data is greater than 0.35 times of the maximum value of the cutter disc torque smooth data.
If not, judging whether the minimum value point meets a preset second condition or not.
And if the second condition is met, determining the time point corresponding to the minimum value point as a first time point of the starting point of the ascending segment and the ending point of the idle push segment.
Wherein the second condition is: and third cutterhead torque smooth data are included in the cutterhead torque smooth data after the time point corresponding to the minimum value point.
Wherein, the cutterhead torque smooth data between the time point corresponding to the third cutterhead torque smooth data and the time point corresponding to the minimum value point is monotonously not reduced or the reduction amplitude of the cutterhead torque smooth data in each period between the time point corresponding to the third cutterhead torque smooth data and the time point corresponding to the minimum value point is less than 0.35 times of the increase amplitude; and the difference between the third cutterhead torque smoothing data and the minimum value is greater than 0.75 times the maximum value of the cutterhead torque data.

and acquiring a minimum value point in the cutterhead torque data in the TBM tunneling cycle according to the cutterhead torque data in the TBM tunneling cycle.
And judging whether the minimum value point meets a preset first condition or not.
If so, determining the time point corresponding to the minimum value point as a first time point of the starting point of the ascending segment and the ending point of the idle push segment.

In this embodiment, the start point of the ascending section is determined only by the cutter torque. Concise logic brings better generalization capability, and only the cutter head torque is used for judgment, so that more legal cycles are run out of the program.
In this embodiment, since the cutter head torque is a passive parameter, problems caused by some subjective operations can be avoided. For example, in the case of the analysis of the propulsion speed, the propulsion speed is manually controlled, so that the propulsion speed may suddenly increase or decrease several times in the idle section of some data, thereby confusing the algorithm. This problem can be avoided by using only passive parameters.
In this embodiment, the step a2-3 includes:

wherein the third condition is: the first total thrust data point is a non-0 value;
the fourth condition is: the total thrust data of the second after the first total thrust data point in the total thrust data is a 0 value;

Then, the validity of the starting point of the temporary halt section is checked:
if the interval with the radius of 20 seconds is the shutdown neighborhood centered at the starting point of the temporary shutdown section, and if the pole difference (maximum-minimum) of the cutterhead torque is smaller than 1/10 of the global maximum value of the cutterhead torque (representing that the cutterhead torque in the shutdown neighborhood is almost unchanged) or the total propulsion force at the starting point of the temporary shutdown section is smaller than 1/5 of the maximum value of the total propulsion force (representing that the total propulsion force at the starting point of the temporary shutdown section is small, meaning that the total propulsion force has already fallen), the starting point of the temporary shutdown section is disqualified, so that the temporary shutdown section is likely to continue to search forward from the current point. If the starting point of the temporary stopping section is full enough to use the starting point of the temporary stopping section as the center, the interval with the radius of 20 seconds is a stopping neighborhood, and in the neighborhood, if the range (maximum value-minimum value) of the cutter head torque is larger than 1/10 of the global maximum value of the cutter head torque and the total propelling force of the starting point of the temporary stopping section is larger than 1/5 of the maximum value of the total propelling force, the qualified starting point of the temporary stopping section is obtained.

Wherein the third time point is: and the time point when the cutterhead torque reaches the average value of the cutterhead torque in the first time period for the first time in the TBM tunneling cycle.
