For realizing the comprehensive monitoring of the ships and warships, the internet of things (i.e., IOT) technology is adopted by the local control system, which consists of the sensing layer, the transmission layer and the whole ship monitoring layer. First, state data is collected by various high-precision sensors of the sensing layer, and then transmitted to the entire ship monitoring layer via the entire ship transport layer based on Modbus TCP/IP design. The local control system is based on the STM32 MCU. It integrates functions such as signal acquisition, Ethernet, CAN bus communication, interactive display, and fault diagnosis. The effectiveness, practicability and flexibility of the on-site control system were verified by a ship propulsion experimental system. The on-site results can provide and verify big data technical support for different regions, regulatory agencies and equipment maintenance of the whole ship.
