Sensor Bus System Design for Structure Damage Monitoring of Offshore Platform
海洋平台结构损伤监测的传感器总线系统设计

A Sensorbus system of data acquisition and information preprocessing and transmitting system for structure damage monitoring is developed based on the fieldbus control area net and object linking and embedding for process control. For sharing and cooperating information came from sensor bus, an operation rule of opened and linked object were embedded into sensor bus. The strategy of saving data grounded on probability distance was developed and implanted into the application layer for the effective saving for great volume data acquiring. The simulation of sensor bus shows that the speed and efficiency of sensor bus are reliable and precise. The result demonstrates that sensor bus is a very useful way for long term monitoring of large structural health.
