Marine oil spill has caused great environmental pollution. Therefore, the analysis of marine oil spill control based on discrete mathematics is studied. Based on the complex situation at sea, an on line monitoring and control system for offshore oil spill including an oil spill online monitoring subsystem and an oil spill integration subsystem is designed. The on-line monitoring subsystem of the oil spill establishes the land data center by the integration technology, uses the data center to monitor the pollution accidents such as oil spill and the like of the offshore oil platform, analyzes the multi-source monitoring data returned by the processing and reports the monitoring and early warning information, and expands the multi-source data receiving processing and the visual display. The main system uses the current loop discrete control model to design the PWM rectifier control module, the real-time dynamic visualization module based on the “oil particle” model, and the interactive fence distribution control based on the triangle partition algorithm to realize the oil spill control. Experiments show that the system could effectively monitor the oil spill on the sea surface, simulate the marine oil spill movement process under complex environmental conditions, and have a good step response.
