Design And Research Of Cabin Monitoring System Based On CAN Bus

Globalized economy increasingly global trade transport is heavily dependent on maritime transport, economic development, promote the rapid development of the shipbuilding industry, the traditional cabin surveillance systems are becoming increasingly difficult to meet the increasingly stringent technical requirements, but also to adapt to not the rapid development of the shipbuilding industry technical level. Many reasons for making the structure of the ship due to the development of the shipbuilding industry increasingly stringent requirements for its function, more sophisticated, cabin control system plays a very important role in the work of the entire ship sailing process, research and development The modern vessel monitoring system for the development of the shipbuilding industry as a whole is very important practical significance. China’s shipbuilding industry started relatively late development was limited, the study of new monitoring system is of great significance for promoting the development of China’s shipbuilding industry prospects and our import and export economy.Read a lot of references on the basis of in-depth specific understanding of marine engine room monitoring system must be completed. This paper describes the process of development of the domestic and international cabin monitoring system, illustrates the advantages and disadvantages of a number of domestic and international cabin monitoring system, and then a detailed overview of the most widely used several fieldbus advantages and disadvantages of the application of occasions, the final design to complete the program of the cabin control system using CAN bus.The monitoring node hardware design, the choice of the STM32F107chip as a distributed unit controller, the STM32F107with two CAN2.0B interface, and Ethernet10/100MAC, able to fully achieve the required functions. CAN transceiver to TJA1050module as in the design process, in order to strengthen the modular design, the use of STM32F107chip as the core design and development related to the signal acquisition circuit and the use of a variety of sensors types of signal cabin equipment acquisition; and the interference problem analysis and research. STM32F107microcontroller control node hardware design, microcontroller peripheral circuit design and CAN bus converter circuit design, in order to achieve the kind of signal acquisition and processing. Monitoring node software design, software design content including CAN bus communication transfer program design, including the initialization of the program to accept, the send program based Fameview host computer interface design, features and advantages and disadvantages of Fameview simple and elaborate, the use of Fameview production control the main interface.Article made design summing up the work, Vessel Monitoring System designed in this paper is based on the operating characteristics of the CAN bus combined with Ethernet technology in order to achieve redundancy control, specific work microcontroller peripheral circuit design and CAN bus converter circuit design, with broad prospects for development and practical significance.
