All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of the present invention provides a system for collecting load data of a rotary drilling tool, as shown in fig. 1, where the rotary drilling tool includes a base 10 and a cutting pick 20 connected to the base 10. The base 10 is generally a cylindrical structure, and the top space is free space, so that a certain space is provided at the top of the base for installing the data acquisition device.
As shown in fig. 1, the acquisition system includes a data acquisition device 30 and a first stress acquisition device 40. The data acquisition device 30 is arranged on the top of the base body 10, and the data acquisition device 30 is provided with a data storage unit and a data acquisition unit connected with the data storage unit. The data storage unit is used for storing the data acquired by the data acquisition unit and the first stress acquisition device, and the data acquisition unit is used for acquiring load data at the top of the substrate 10. For example, the data acquisition unit may be an acceleration sensor, a speed sensor, or the like. In this embodiment, the specific collected data and specific structure of the data collecting unit are not limited, and may be set correspondingly according to actual situations.
The data storage unit may be a data storage card, or other storage device, etc. The data acquisition unit and the first stress acquisition device are both connected with the data storage unit and are used for storing first acquisition data of the data acquisition unit and second acquisition data of the first stress acquisition device.
The first stress pick-up device 40 is arranged on the pick 20, in particular, a routing channel is started at the inner side wall of the base body 10 for arranging connecting wires of the first stress pick-up device 40 and the data storage unit. For example, a deep hole drilling process may be used to form a routing channel in the inner sidewall of the substrate 10.
The first stress riser 40 may constitute a strain gage circuit by using a strain gage, for example, a half-bridge stress gage circuit, a full-bridge stress gage circuit, or the like may be constituted by using a strain gage. The corresponding setting can be carried out according to actual conditions.
According to the acquisition system for the load data of the rotary drilling tool, provided by the embodiment, the first stress acquisition device is arranged on the cutting pick, so that the load data below the ground can be measured; and the inner side wall of the matrix is provided with the wiring channel, so that collected data can be sent to the data storage unit through the wiring in the wiring channel, and the data transmission is realized. The wiring channel is arranged on the inner side wall of the base body, so that the arrangement of the wiring is not influenced in the working process of the rotary drilling tool, and the reliability of data transmission can be ensured. Therefore, the first data acquisition device arranged at the top of the matrix is used for acquiring data above the ground, and the first stress acquisition device arranged on the cutting pick is used for acquiring data below the ground, so that the comprehensiveness of load data acquisition can be ensured, and data support is provided for the accurate programming of the follow-up load spectrum.
As an alternative implementation manner of this embodiment, the data acquisition unit includes an acceleration sensor, and the acceleration sensor is disposed on top of the base body and is connected to the data storage unit. Further, the data acquisition unit also comprises an integration circuit, wherein the input end of the integration circuit is connected with the output end of the acceleration sensor and is used for integrating the acquired acceleration signals to obtain speed signals; the output end of the integrating circuit is connected with the data storage unit, and the speed signal obtained by processing the acceleration signal is stored in the data storage unit.
Optionally, the data storage unit and the data acquisition unit are packaged in the data acquisition device. That is, the data acquisition device has a housing cavity in which a data storage unit and a data acquisition unit are disposed, and the data storage unit is connected with the first stress acquisition device through a data input port reserved on the data acquisition device. The data storage unit and the data acquisition unit are packaged in the accommodating cavity of the data acquisition device, so that equipment maintenance is facilitated, and the working stability of the acquisition system is improved.
As an optional implementation manner of this embodiment, the first stress collecting device includes a first strain gauge and a first temperature compensation block. The number of the first strain gauges and the number of the first temperature compensation blocks included in the first stress collecting device may be set correspondingly according to practical situations, and the first stress collecting device is not limited in any way. The first stress-collecting means provided on the cutting pick may be one, two or more, and the specific number thereof is not limited in this embodiment. Each first stress acquisition device is uniformly arranged on the surface of the cutting pick, and can be correspondingly arranged according to actual requirements.
For each first stress acquisition device, the first strain gauge is attached to the cutting pick, and the first strain gauge and the first temperature compensation block included in the first stress acquisition device form a full-bridge stress acquisition circuit for acquiring stress of the cutting pick in the working process. Because the collection of the load data needs to last a working cycle for a period of time as long as a plurality of hours, the interference can be reduced by selecting the full-bridge measuring circuit when the strain measurement is carried out, and the stability of the long-term measurement of the data is ensured.
Optionally, the material of the first temperature compensating block is the same as the material of the pick. The full-bridge measuring circuit is formed by the temperature compensation block which is made of the same material as the cutting pick and the first strain gauge, so that on one hand, the data drift of instruments and equipment is reduced, and on the other hand, the temperature compensation is performed.
In alternative implementations of the present embodiment, as shown in FIG. 1, the data acquisition system further includes a second stress acquisition device 50. The second stress-collecting device 50 is arranged on top of the base body 10 and is connected with a data storage unit in the data-collecting device. The second stress acquisition device arranged on the top of the matrix is used for measuring positive top strain and shear strain, so that positive pressure and torque can be indirectly measured.
The specific structure of the second stress collecting device 50 may be the same as or different from that of the first stress collecting device 40, and the specific structure is not limited in any way, and the second stress collecting device may be set correspondingly according to actual requirements.
As described above, the data acquisition system may be divided into two sets of acquisition systems, one being a data acquisition unit disposed within the data acquisition device and the other including a first stress acquisition device disposed on the pick and a second stress acquisition device disposed on the top of the substrate. The data types collected by the two sets of data collection systems can be divided into an acceleration/speed collection system and a stress collection system.
Because the data acquisition system comprises two sets of acquisition systems, the two sets of acquisition systems respectively acquire data, and the data acquired by the two sets of data acquisition systems need to be subjected to synchronous acquisition point determination in order to acquire load data at the same moment. Also, since both the acceleration/velocity acquisition system and the stress acquisition system are the same, the force signals acquired by both systems are the same at the same time. Therefore, the force signal acquisition circuits can be respectively arranged in the two sets of systems to acquire corresponding force signals. And then comparing and analyzing the force signals acquired in the two sets of systems, and finding out the acquisition points with the same force to determine the synchronous signal acquisition points.
As an alternative implementation of this embodiment, the data acquisition system further includes a first force signal acquisition circuit and a second force signal acquisition circuit. The first force signal acquisition circuit is arranged in the acceleration/speed acquisition system, and the second force signal acquisition circuit is arranged in the first force acquisition device. Specifically, the first force signal acquisition circuit is connected with the first data acquisition unit and the data storage unit. The second stress signal acquisition circuit is connected with the first stress acquisition device and the data storage unit.
In the working process of the rotary drilling tool, the two sets of systems respectively acquire load data, the acceleration/speed acquisition system acquires acceleration signals, speed signals and first force signals, and the stress acquisition system acquires stress signals and second force signals. Because the two sets of systems work separately, the acquisition time points and the acquisition frequencies are different, and the corresponding acquisition data can be obtained. For the whole acquisition system, the load data at the same moment is finally needed to be obtained, so that the time point alignment of the acquired data of the two sets of systems is needed, namely, the synchronous signal acquisition point is determined.
Specifically, as described above, although the two systems are independently operated, at the same time, the force signals acquired by the two systems are the same. Therefore, the acquisition points of the same force signal acquired by the two sets of systems can be found by comparing the first force signal and the second force signal, and the acquisition points are determined as the synchronous signal acquisition points of the data acquisition device and the first stress acquisition device.
As an alternative implementation manner of this embodiment, a signal sampling circuit and a comparison circuit may be used to find the sampling points of the same force signals of the two systems.

Fig. 4 is a flowchart of a method for acquiring load data of a rotary drilling tool according to an embodiment of the present invention, as shown in fig. 4, the flowchart includes the following steps:
S21, acquiring first acquired data and second acquired data in a data storage unit of the data acquisition device.
The first data collection is collected by a data collection unit in the data collection device, the second data collection is collected by a first stress collection device, the data collection device is arranged at the top of the base body, the first stress collection device is arranged on a cutting pick, a wiring channel is formed in the inner side wall of the base body, and the first stress collection device is connected with the data storage unit through the wiring channel.
Please refer to the embodiment shown in fig. 3 for details of S11, which is not described herein.

Specifically, the step S22 may include the following steps:
s221, acquiring a first force signal and a second force signal of the first force signal acquisition circuit and the second force signal acquisition circuit.
The first force signal acquisition circuit is respectively connected with the first data acquisition unit and the data storage unit, and the second force signal acquisition circuit is connected with the first stress acquisition device and the data storage unit.
For clarity of description, the first force signal corresponds to an acceleration/velocity acquisition system and the second force signal corresponds to a stress acquisition system. Wherein, the first force signal and the second force signal are both stored in a data storage unit of the data processing device.
S222, determining synchronous signal acquisition points of the first acquired data and the second acquired data based on the first force signal and the second force signal.
After the electronic device obtains the first force signal and the second force signal, the electronic device can compare the first force signal with the second force signal to find the collection time point of the same force signal as the first force signal and the second force signal.
As an alternative implementation manner of this embodiment, the step S222 may include the following steps:
(1) The method comprises the steps of acquiring a first acquisition frequency of a data acquisition device and a second acquisition frequency of a first stress acquisition device.
Because the acquisition frequency can influence the number of data points acquired in unit time, the first acquisition data and the second acquisition data are aligned through the acquisition frequency, and the data processing amount is reduced.
(2) Searching a point of the first error in the first force signal and the second force signal within a preset range to obtain an initial synchronous signal acquisition point.
The electronic equipment searches a point of which the first error is within a preset division in the first force signal and the second force signal by traversing the first force signal and the second force signal so as to obtain an initial synchronous signal acquisition point.
(3) Starting point is carried out by the initial synchronous signal acquisition point, the comparison point of the first force signal and the second force signal is determined by the first acquisition frequency and the second acquisition frequency, and the comparison of the acquisition points with the preset number is carried out, so as to determine the target synchronous signal acquisition point.
After the initial synchronous signal acquisition point is determined, the initial synchronous signal acquisition point is used as an analysis starting point of the first acquisition data and the second acquisition data, and a comparison point of the first acquisition data and the second acquisition data is determined by using the first acquisition frequency and the second acquisition frequency. For example, where the first acquisition frequency is 100Hz and the second acquisition frequency is 200Hz, every other data point in the second acquisition data is compared to the acquisition data points of the 100Hz system.
The electronic device may continuously compare a preset number of points (e.g., 10, or 20, etc.), and if the errors of the preset number of comparison points are all within a preset range, it indicates that the starting point selection is correct, and the initial synchronization signal acquisition point is taken as the target synchronization signal acquisition point. Otherwise, the determination of the starting point will be resumed.
The difference of the acquisition frequencies also affects the comparison of the signal points, so that the acquisition frequencies of the two sets of acquisition systems are introduced in the determination process of the synchronous signal acquisition points, and the accuracy of the determined target synchronous signal acquisition points can be ensured.
As a specific implementation manner of this embodiment, as shown in fig. 5, S222 may be implemented by the following steps:
(1) Finding the point where the first error is 2%;
(2) Comparing a 200Hz acquisition system with a system with an acquisition frequency of 100Hz at intervals, and continuously comparing 10 points;
(3) Whether the 10 points are all within 2%; if yes, executing the step (4); otherwise, executing the step (1);
(4) The starting point is selected correctly.
S223, carrying out data analysis on the first acquired data and the second acquired data by utilizing the synchronous signal acquisition points, and determining the load data of the rotary drilling tool.
After the electronic equipment analyzes and determines the synchronous signal acquisition point, the synchronous signal acquisition point can be utilized to align the first acquisition data with the second acquisition data to obtain different types of acquisition data at the same moment so as to perform subsequent data analysis and determine the load data of the rotary drilling tool.
According to the method for acquiring the load data of the rotary drilling tool, for the two sets of acquisition systems, namely the data acquisition device and the first stress acquisition device, corresponding force signals at the same moment are the same. Therefore, corresponding force signal acquisition circuits are respectively arranged corresponding to the two sets of acquisition systems, and the synchronous signal acquisition points of the two sets of acquisition systems can be determined through the two sets of acquired force signals, so that the accuracy of load data determination is improved.
