Synchronization method and device for artificial source electromagnetic method transmitter and receiver

Abstract

A method and device for synchronizing an artificial source electromagnetic method transmitter and receiver, the method comprising: the transmitter modulates the carrier wave of the work order on the current value, and sends it to the ground through the transmitting electrode, and is received by the electric field and magnetic field sensors; the receiver Process the signals received by the electric field and magnetic field sensors, demodulate the work instructions sent by the transmitter; the transmitter and receiver perform time synchronization according to the task information, the transmitter transmits current according to the above task information, and the receiver performs signal reception according to the task information. Execute human exploration tasks. The synchronization method of the present invention can carry out carrier communication through the signal transmitted by the transmitter, realize the transmission of communication data from the transmitter to the receiver, and complete the distribution and synchronization of data information such as schedule and operation time. This solution is conducive to realizing the autonomous interaction between the transmitter and receiver, enhancing the automation level in the operation process, reducing the workload of operators, reducing human errors, and improving operation efficiency and quality.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic prospecting, and in particular relates to a synchronization method and device for an artificial source electromagnetic method transmitter and receiver. Background technique [0002] Introduction to the Prior Art The electromagnetic method is one of the geophysical methods and is widely used in exploration operations such as geological structures, mineral oil and gas resources, and geothermal. The electromagnetic method is divided into natural source and artificial source. When the artificial source electromagnetic method works, the transmitter and the receiver need to work at the same time, and the time is strictly synchronized. Complete the job flow. [0003] At present, when the artificial source electromagnetic method is used, the operators communicate with each other, confirm that the same schedule is used, and then start the transmitter and receiver. There is no interaction between t...
