This invention belongs to the field of electrical communication technology and is a multi-terminal intelligent communication system and data transmission method for oil pumping units. It includes: several oil pumping units, each equipped with a communication module connected to a photoelectric conversion module. The photoelectric conversion module sends a raw optical data link to a splitter via a corresponding optical splitter cable. The splitter transmits the received raw optical data link to a host computer via a main optical cable. The communication module uses either RS-485 or ASCII communication. The host computer determines whether the optical attenuation exceeds a preset maximum optical attenuation threshold. If it does, the host computer determines that the optical attenuation of the raw optical data link transmitted via the corresponding optical splitter cable is unqualified. At this time, the host computer sends a modulation signal to the oil pumping unit with unqualified optical attenuation and the next oil pumping unit in sequence, so that the raw optical data links sent by the two oil pumping units are combined into a new optical data link at the splitter. This enables the receiving end to accurately obtain information from the new optical data link even when the optical attenuation of the raw optical data link of the oil pumping unit does not meet the requirements.
