specific Embodiment

[0078] figure 1 A flowchart of a method for controlling a compass bird provided by an embodiment of the present invention is shown, and the method includes the following steps:

[0079] Step 110: Control the main control single-chip microcomputer to enter the first deep sleep state when not processing work.

[0080] Step 120: The main control microcontroller receives an external interrupt signal, and switches from the first deep sleep state to the first working state.

[0081] Step 130: The peak detection circuit detects whether there is a communication carrier signal.

[0082] Step 140: If the peak detection circuit does not detect the communication carrier signal, the data demodulation unit is not activated.

[0083] Step 150: If the peak detection circuit detects the communication carrier signal, the data demodulation unit starts to demodulate the communication carrier signal, and the communication demodulation module sends the demodulated signal obtained by demodulation ...

Abstract

The invention relates to the technical field of the field of surveying, and discloses a compass bird control method and a control device. The method includes: a main control single-chip microcomputer enters a first deep sleep state when not processing work; The first deep sleep state is switched to the first working state; the peak detection circuit detects whether there is a communication carrier signal; if the peak detection circuit does not detect the communication carrier signal, the data demodulation unit does not start; if the peak detection circuit detects the communication carrier signal , the data demodulation unit is activated to demodulate the communication carrier signal, and the communication demodulation module sends the demodulated signal obtained by demodulation to the main control single-chip microcomputer. Through the above method, the power consumption control method of the main control single-chip microcomputer and the communication demodulation module in the embodiment of the present invention can greatly reduce the power consumption of the compass bird, and correspondingly reduce the frequency of replacing the battery of the compass bird, so as to prolong the underwater work of the compass bird time, and improve the efficiency of compass bird work.

Description

technical field [0001] The invention belongs to the technical field of surveying, and in particular relates to a compass bird control method and a control device. Background technique [0002] With the development of offshore oil exploration technology to the direction of wide frequency and wide azimuth, the exploration system requires the geophone to have more accurate positioning ability. With seismometers arranged at different depths, the seismic wave data collected with broadband information can obtain richer stratigraphic imaging maps, which is of great significance to geological data interpretation and oil and gas exploration. However, if the geophone cannot be accurately and stably displayed to different depths, the obtained stratigraphic data cannot be continuously imaged, and the obtained data may even be unreliable. Therefore, in order to collect and analyze broadband geological profile data, it is not only necessary to improve the broadband characteristics of the...
