102. The computer device determines a first time range and a second time range for the seismic data, respectively.
The first time range is a time range corresponding to zero value data in the seismic data, and the second time range is a time range of losing the seismic data. The first time range and the second time range respectively comprise a first time range and a second time range which respectively correspond to the abnormal wireless nodes. The abnormal wireless nodes are nodes in the plurality of wireless nodes, and zero value data and loss conditions exist in seismic data collected by the abnormal wireless nodes; optionally, any abnormal wireless node corresponds to at least one of the first time range and the second time range, and in the embodiment of the present application, the abnormal wireless node corresponds to the first time range and the second time range. Optionally, the first time range and the second time range corresponding to the abnormal wireless node are multiple, that is, the abnormal wireless node corresponds to the time range of multiple zero value data and the time range of multiple lost seismic data.
For the ith wireless node, the seismic data of the wireless node comprise a plurality of channels of data which are sequentially connected, the acquisition time length of the plurality of channels of data is the target time length, and the computer equipment respectively acquires a first time range, a receiving line number, a receiving point number and the like of each channel of data from the data channel head of each channel of data; its corresponding first time range is denoted as ts i1 To te i1 ，ts i2 To te i2 ，……，ts iu To te iu ，……，ts ip To te ip The method comprises the steps of carrying out a first treatment on the surface of the Optionally, the zero value data is at least one, and u represents continuous channel data of the ith wireless nodeSequence number of continuous zero value data segment, p represents total number of time range of continuous zero value data segment in continuous channel data of ith wireless node, ts iu A start time, te, representing a nth consecutive zero value data segment in the continuous channel data of the ith wireless node iu Representing the expiration time of the u-th consecutive zero-value data segment in the continuous-track data of the i-th wireless node.
In some embodiments, the determining of the second time range comprises the steps of: the computer equipment determines the difference value of the initial time corresponding to any two adjacent channels of data in the multi-channel data respectively to obtain a plurality of difference values. If the plurality of differences comprise target differences exceeding the target duration, the computer equipment takes the sum of the starting time of the first data and the target duration as the starting point of the second time range, takes the starting time of the second data as the ending point of the second time range, and the first data and the second data are respectively the former data and the latter data in the two data corresponding to the target differences.
Optionally, the computer device acquires the start time and the acquisition duration of each data channel from the data channel head of each data channel respectively. For example, the computer device acquires the kth track data in the continuous track data of the ith wireless node from the track head data with a start time t ik It should be noted that, the track length, i.e. the acquisition duration, of continuous track data of any abnormal wireless node is equal, i.e. the target duration, denoted by L.

In this embodiment, since the acquisition time periods of the two adjacent data are both the target time periods, and if the difference between the start times of the two adjacent data is greater than the target time periods, it is indicated that no seismic data are acquired in a time range greater than the target time periods, that is, a situation that the seismic data are lost exists, so that the sum of the start time of the first data and the target time period is used as the start point of the second time range, the start time of the second data is used as the end point of the second time range, and the accuracy of determining the second time range is improved.
103. The computer device obtains firing times for a plurality of first shots.

For each abnormal wireless node, the computer equipment uniformly sorts a plurality of corresponding first time ranges and a plurality of corresponding second time ranges according to the starting time of each time range; then, comparing the starting time and the ending time of any two adjacent time ranges by the computer equipment, if the ending time of the former time range and the sampling points corresponding to the starting time of the latter time range are different by only one sampling point, combining the two time ranges by the computer equipment to obtain a third time range, wherein the starting time and the ending time of the third time range are respectively the starting time of the former time range and the ending time of the latter time range, and the first time range, the second time range and the third time range are all invalid time ranges; the computer equipment takes the time range with the duration exceeding the target threshold value in the invalid time range as a target time range; it should be noted that, since the first time range, the second time range, and the third time range are all plural, the target time range is plural, that is, the plural abnormal wireless nodes respectively correspond to the plural target time ranges.
The target time length can be set and changed according to the needs; optionally, the target duration is 120s. It should be noted that, in the process of collecting the seismic data, zero value data or a shorter time length of losing the seismic data may occur due to random errors or systematic errors, and in this embodiment, the accuracy of determining the target time range is ensured by taking the time range in which the time length exceeds the target threshold value as the target time range.
In some embodiments, the computer device obtains a total duration of the wireless node for collecting the seismic data based on the data trace head of any abnormal wireless node, and further determines a difference value between the total duration and a target time range, so as to obtain an effective time range of the seismic data, wherein the effective time range is a range for recording the effective seismic data; thereby facilitating subsequent data integrity checks of the seismic data based on the effective time range.
