Application of wireless sensor network in ship control system

Ship control system needs a redundant network for security. In order to solve the problem of ship wired network, the paper designs wireless sensor network as redundant network of ship control system. A ship control system based on wireless sensor network is designed. The STM32F103 processor is the core of the wireless sensor network nodes, which runs on the Mindows real-time operating system, uses the coulombmeter method to monitor the battery level. In view of some problems in wireless network control system, the design of the ship course-keeping controller combines gray model with the robust PID control based on the algorithm of closed-loop gain shaping and takes compensation control of time delay and packet loss. The experimental results prove that the scheme is feasible and effective on network simulation platform. It is a beneficial attempt to apply wireless sensor network to ship control system.
