Separated multi-core transmitting devices based on ground transient electromagnetic methods

A separated multi-core transmitting device based on a ground transient electromagnetic method, comprising:

• a rectangular transmitting coil, wherein the rectangular transmitting coil includes a cable I, a cable II, a cable III, and a cable IV, each of the cable I, the cable II, the cable III, and the cable IV is provided with N wires, two ends of each of the N wires is provided with a sub connector and a female connector, respectively, the sub connectors of the wires within each cable are labeled sequentially with uppercase letters, and the female connectors of the wires within the each cable are labeled sequentially with lower case letters;
• the sub connectors are connected with sub connector interfaces, the female connectors are connected with female connector interfaces, and the sub connector interfaces and the female connector interfaces are detachably connected;
• and
• the sub connectors of the cable I are connected with the female connectors of same letters of the cable II, the sub connectors of the cable II are connected with the female connectors of same letters of the cable III, the sub connectors of the cable III are connected with the female connectors of same letters of the cable IV, and the sub connectors of the cable IV are connected with the female connectors of next letters of same letters of the cable I;
• and a first wire of the female connectors of the cable I is led out to serve as a positive electrode of a transient electromagnetic instrument transmitter, and a last wire of the sub connectors of the cable IV is led out to serve as a negative electrode of the transient electromagnetic instrument transmitter.
