The invention discloses a data processing method and device. The method comprises the steps of receiving an acquisition signal sent by an acquirer arranged on an underground power pipeline, wherein the acquisition signal contains acquisition data and a pipeline segment mark; acquiring current power service data; calculating the acquisition data and the current power service data according to a preset data processing model so that pipeline field data can be obtained; transmitting the pipeline field data to a pipeline segment corresponding to the pipeline segment mark according to the pipeline segment mark and transmitting the pipeline field data to an external device through a wireless transmitting device arranged at the position of the pipeline segment. By the adoption of the data processing method and device, underground pipe network field data sharing quality can be improved effectively.
