In order to improve the technical level of marine test, a measurement and control system for real ship test is designed. The computer is used as the main control platform, the real boat thruster is taken as the research object, and the pressure, torque and other parameters are collected by sensors. The data is displayed on the computer screen and stored in the hard disk. The test results show that the device can realize the collection and storage of test data, provide condition support for the realization of real ship sea test, and provide reference for the research of unmanned craft.
