Seismic exploration data forwarding method, repeater, related equipment and transmission system

The invention provides a seismic exploration data forwarding method, a repeater, related equipment and a transmission system. The method comprises the following steps: receiving a trigger instructionsent by a seismic instrument at a first frequency; converting a forwarding frequency corresponding to the trigger instruction into a pre-stored second frequency, wherein the value of the second frequency is different from the value of the first frequency; and forwarding the trigger instruction to a unique corresponding field device at the second frequency, wherein the field device is one of a plurality of field devices arranged in a seismic exploration field, the values of the second frequencies corresponding to the field devices are different, frequency conversion is carried out on report information received from the uniquely corresponding field device, and the report information after frequency conversion is forwarded to the seismic instrument. According to the invention, there is no need to set a main repeater
