Description
Technical Field
The application relates to the technical field of oil exploration, in particular to a clock calibration method of acquisition equipment and the acquisition equipment.
Background
As core equipment for exploration, the accurate and efficient operation of exploration instruments such as acquisition equipment for acquiring seismic data and the like ensures the smooth completion of exploration tasks. With the great development of electronic communication technology, the collection equipment is also continuously updated. At present, before the collection equipment is used for executing a production task, workers can carry out daily inspection and annual inspection on the collection equipment so as to ensure that the performance of the collection equipment can meet the requirements of field production. However, due to the influence of factors such as temperature, construction environment and system design, the acquisition equipment is easy to generate timing errors due to clock drift, and if the self control and adjustment of the acquisition equipment fails, a time label error is generated, so that the acquisition time is asynchronous with the excitation time, a waste cannon is generated at the moment, and huge economic loss is brought to a construction unit.
Therefore, how to check whether the clock of the acquisition device is accurate is required, so that economic loss caused by clock drift of the acquisition device is reduced, and the problem to be solved is also required.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present application are provided herein to explain the present application and not to limit the present application.
The embodiment of the application provides a method for checking a clock of acquisition equipment, and as shown in fig. 1, the method comprises steps 101 to 103:
The initial moment is the moment when the acquisition equipment starts to perform acquisition work after being started.
The acquisition equipment is the time 0 which is the first sampling point for starting acquisition work acquisition after the acquisition equipment is powered on, namely the initial time, the time is synchronous with a GPS second pulse signal, and the clock drift is difficult to detect in a short time, so the preset time period can be set to be a longer time period, meanwhile, the length of the preset time period cannot exceed 24 hours because the acquisition equipment generally resets once after continuously working for 24 hours, the preset time period can be 23 hours or 22 hours and the like, and the maximum clock error of the acquisition equipment can be detected in the preset time period close to 24 hours.
And 102, comparing the coincidence condition of the rising edge of the GPS second pulse signal in the acquired data record and the whole second time counting line of the acquired data record.
The time for acquiring data deviates from the actual time due to clock anomalies such as clock drift of the acquisition device, for example, the time required by the acquisition device to acquire 1000 sampling points is 1 second theoretically, but the clock of the acquisition device becomes slow, and only 999 sampling points may be acquired within 1 second; if the clock of the acquisition device is fast, 1001 sampling points may be acquired within 1 second, and after the GPS second pulse signal is taken as the input signal of the acquisition device and acquired, the rising edge of the GPS second pulse signal coincides with the 999 millisecond or 1001 millisecond time line, but does not coincide with the whole second time line. Therefore, whether the clock of the acquisition equipment is abnormal or not can be determined according to the coincidence condition of the rising edge of the GPS second pulse signal and the whole second time counting line.
And 103, if the rising edge of the GPS second pulse signal is not coincident with the whole second time counting line, determining that the clock of the acquisition equipment is abnormal.
Illustratively, the time taken to acquire 1000 samples is 1 second theoretically, if the rising edge of the GPS second pulse signal coincides with the whole second time line, it indicates that the clock of the acquisition device is normal, and if the rising edge of the GPS second pulse signal does not coincide with the whole second time line, it indicates that the clock of the acquisition device is abnormal.
As shown in fig. 2, a comparison graph of the whole second time line of the data record collected by the normal collection device and the rising edge of the collected GPS second pulse signal is shown. As can be seen in fig. 2, the entire second time line of the acquired data record coincides with the rising edge of the GPS second pulse signal. As shown in fig. 3, a comparison graph of the whole second time line of the acquired data record of the abnormal acquisition device and the rising edge of the acquired GPS second pulse signal shows that, as shown in fig. 3, the whole second time line of the acquired data record does not coincide with the rising edge of the GPS second pulse signal.
Before continuously collecting the GPS second pulse signal output by the GPS signal source, judging whether the voltage peak value of the GPS second pulse signal is larger than the maximum voltage which can be detected by the collecting equipment; if the voltage peak value of the GPS second pulse signal is larger than the maximum voltage which can be detected by the acquisition equipment, the GPS second pulse signal is subjected to voltage reduction processing, so that the signal peak value of the GPS second pulse signal is not larger than the maximum signal threshold value which can be acquired by the acquisition equipment, and the phenomenon that time accuracy is influenced due to maladjustment of an Analog-to-Digital Converter (ADC) caused by overlarge signals is avoided. For example, if the peak voltage value of the GPS second pulse signal is 3.3 volts (V) and the maximum voltage that can be monitored by the acquisition device is 2.5V, the voltage of the GPS second pulse signal needs to be reduced below 2.5V by the voltage reduction circuit.
In addition, in order to avoid data pickup errors caused by signal distortion, in the embodiment of the present application, before continuously acquiring the GPS second pulse signal output by the GPS signal source, the impedance of the GPS second pulse signal is also matched with the input impedance of the acquisition device.
After the clock in the acquisition equipment is determined to be abnormal, a clock abnormity warning signal can be sent out so as to prompt an operator to timely remind the acquisition equipment of potential clock abnormity hidden danger and need to be maintained.
In the embodiment of the application, a GPS second pulse signal provided by a GPS signal source is used as an input signal of a collection input end, then the rising edge of the GPS second pulse signal in a collection data record obtained by collecting the GPS second pulse signal in a preset time period by a collection device is compared with the whole second time counting line of the collection data record, and whether the clock of the collection device is abnormal or not is further determined. Because the input signal of the acquisition equipment is a GPS pulse-per-second signal which is generated in absolute time of whole second with extremely high accuracy, the rising edge of the GPS pulse-per-second signal in the acquisition data record is compared with the whole second time line of the acquisition data record, and whether the clock of the acquisition equipment is abnormal or not can be accurately determined. The clock verification method is simple and easy to implement, has low cost, and can timely and accurately discover potential clock abnormity hidden dangers of the acquisition equipment, thereby reducing economic loss caused by clock drift of the acquisition equipment.

and an alarm module 407, configured to send a clock abnormality alarm signal after the determination module 403 determines that the clock in the acquisition device is abnormal.
In the embodiment of the application, a GPS second pulse signal provided by a GPS signal source is used as an input signal of a collection input end, then the rising edge of the GPS second pulse signal in a collection data record obtained by collecting the GPS second pulse signal in a preset time period by a collection device is compared with the whole second time counting line of the collection data record, and whether the clock of the collection device is abnormal or not is further determined. Because the input signal of the acquisition equipment is a GPS pulse-per-second signal which is generated in absolute time of whole second with extremely high accuracy, the rising edge of the GPS pulse-per-second signal in the acquisition data record is compared with the whole second time line of the acquisition data record, and whether the clock of the acquisition equipment is abnormal or not can be accurately determined.
