The two sets of data acquisition systems can be divided into an acceleration/speed acquisition system and a stress acquisition system according to the data types acquired by the two sets of data acquisition systems.
Because the data acquisition system comprises two sets of acquisition systems which respectively acquire data, in order to acquire load data at the same moment, the data acquired by the two sets of data acquisition systems needs to be synchronously acquired to determine an acquisition point. And because the force signals collected by the two systems are the same at the same time no matter the acceleration/speed collection system or the stress collection system. Therefore, the two systems can be respectively provided with a force signal acquisition circuit to acquire corresponding force signals.

For clarity of description, the first force signal is associated with an acceleration/velocity acquisition system and the second force signal is associated with a stress acquisition system. 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 acquisition data and the second acquisition data based on the first force signal and the second force signal.
After the electronic equipment acquires the first force signal and the second force signal, the first force signal and the second force signal can be compared, and the acquisition time point of the same force signal in the first force signal and the second force signal can be found.
As an optional implementation manner of this embodiment, the step S222 may include the following steps:
(1) and acquiring a first acquisition frequency of the data acquisition device and a second acquisition frequency of the first stress acquisition device.
The acquisition frequency influences the number of data points acquired in unit time, and the first acquisition data and the second acquisition data are aligned through the acquisition frequency, so that the data processing amount is reduced.
(2) And 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 finds a point with a first error 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) And carrying out initial point acquisition by using the initial synchronous signal acquisition points, determining comparison points of the first force signal and the second force signal by using the first acquisition frequency and the second acquisition frequency, and comparing a preset number of acquisition points to determine target synchronous signal acquisition points.
After the initial synchronization signal acquisition point is determined, the initial synchronization 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, a first acquisition frequency of 100Hz and a second acquisition frequency of 200Hz, every other data point in the second acquisition is compared to the acquired 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 within a preset range, it indicates that the starting point is correctly selected, and the initial synchronization signal acquisition point is used as the target synchronization signal acquisition point. Otherwise, the determination of the starting point will be made again.
The contrast of the signal points can be influenced by different acquisition frequencies, so that the acquisition frequencies of 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, the step S222 may be implemented by:
(1) finding a point where the first error is 2%;
(2) comparing the 200Hz acquisition system with a system with acquisition frequency of 100Hz at intervals of 10 points;
(3) whether the errors of 10 points are all within 2%; if yes, executing the step (4); otherwise, executing the step (1);
(4) the starting point is chosen correctly.
And S223, performing data analysis on the first collected data and the second collected data by using the synchronous signal collection point, and determining load data of the rotary drilling tool.
After the electronic equipment analyzes and determines the synchronous signal acquisition points, the first acquisition data and the second acquisition data can be aligned by using the synchronous signal acquisition points to obtain different types of acquisition data at the same time, so that subsequent data analysis is performed, and load data of the rotary drilling tool is determined.
In the method for acquiring load data of the rotary drilling tool, corresponding force signals of the two sets of acquisition systems, namely the data acquisition device and the first stress acquisition device, are the same at the same time. 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.
