Ship Main Engine Revolution Signal Acquisition and Wireless Transmission Simulation System Design

The rotative speed information of ship main engine is a main parameter for re- flecting ship working performance, and also an important information for monitoring engine conditions by turbine engineers. This paper introduces the design process of ship signal acquisition and wireless transmission simulation system and the functions and principles of all parts in use. Based on the design of analog circuit, the automating and wireless acquisition of ship rotative speed signal is achieved, and the trend of ship main engine inspection in the future is predicted. It can replace the existing rotative speed display device within limit and control the cost of engineering and technology and realize the real-time monitoring of ship rotative speed through a verity of remote ports.
