Deepwater marine riser is the key equipment essential for the development of marine oil and gas drilling, as well as the most vulnerable and the most dangerous part of deepwater oil and gas exploration and development. VIV, the bottom of the well head angle is too large, platform of oscillation and jitter factors may cause the platform riser fatigue damage or even fracture damage, not only caused great economic losses, but also induce serious ecological disaster. Marine riser fatigue monitoring is an important guarantee for ensuring the safety of deepwater riser operations, and it also plays an indispensable role in the riser of accident prevention. In order to monitor riser overall response, a lot of discrete distribution monitoring equipment needs to be put along the marine riser by certain rules. Fatigue parameter information transmission is a core of riser fatigue monitoring technology and difficulty. In order to ensure the efficient transmission of fatigue parameters between the measuring point and the receiving end, this paper studies fivepoint communication problems with the receiving end, under the condition of 3 000 m water depth, so that a communication scheme combined time division multiplexing with frequency division multiplexing is proposed. The simulation results show that under the premise of ensuring detection probability, the proposed scheme can effectively overcome the nearfar effect and the interference problem between each measuring point.
