The invention discloses a data processing system for pipelines and cables. The system comprises a basic database, a business processing module and a first processing module, wherein the basic database is used for storing operation parameters, monitored in real time, of a cable; the business processing module is used for at least carrying out online monitoring on a pipeline so as to obtain operation parameters of the pipeline; and the first processing module is connected with each of the basic database and the business processing module, and is used for carrying out data fusion on the operation parameters of the cable and the operation parameters of the pipeline. According to the system, the technical problem that the lean management cannot be satisfied as the pipelines and cables are independently managed in the prior art is solved.
