Method and device for controlling compass bird

Abstract

The invention relates to the technical field of survey, and discloses a compass bird control method and device, and the method comprises the steps: enabling a main control single-chip microcomputer to enter a first deep dormant state when the main control single-chip microcomputer does not process the work; after receiving an external interrupt signal, the master control single-chip microcomputer is switched from a first deep dormant state to a first working state; the peak detection circuit detects whether a communication carrier signal exists or not; if the peak detection circuit does not detect the communication carrier signal, the data demodulation unit is not started; and if the peak value detection circuit detects the communication carrier signal, the data demodulation unit is started to demodulate the communication carrier signal, and the communication demodulation module sends a demodulation signal obtained by demodulation to the main control single chip microcomputer. Through the above mode, the power consumption control method of the master control single-chip microcomputer and the communication demodulation module in the embodiment of the invention can greatly reduce the power consumption of the compass bird, correspondingly reduce the frequency of battery replacement of the compass bird, prolong the underwater working time of the compass bird, and improve the working efficiency of the compass bird.

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...
