Marine Instrumentation Control System Based On CAN Bus

With the rapid development of industrial technology and people’s growing demand formonitoring and control instrumentation has been rapid development, and presents new trends: themeasurement and control range is extended to the three-dimensional, globalization; monitoring andcontrol functions to the systematic, network development; a large number of portable, handheld, andeven personalized instrument development. Instrumentation, intelligent, functional diversification, cannot be separated from the microprocessors and microcontrollers. Eight16-bit microcontrollerprocessing capabilities continue to improve, but limited the ability of the CPU core can no longermeet the needs of the smart meter, so32-bit microcontrollers and microprocessors will become amainstream design.Therefore, the use of powerful32-bit processors to complete the various functions of intelligentinstruments, fieldbus intelligent instrument control functions. The system uses a kernel based on theCortex-M microcontroller applications STM32F107microprocessor peripheral interface, clocked at72MH z-.As a technologically advanced, high reliability, functionality and reasonable cost of remotenetwork communication control mode, the CAN bus has been widely used in automation and controlsystems. CAN bus supports multi-master mode, the communication speed up to1M b it/s,(adistance not exceeding20m), a simple and reliable lines of communication, to facilitate wiring.Fieldbus is one of the hotspots of today’s automation technology development in the field ofcomputer local area network, known as the field of automation. Its appearance between the nodes forthe distributed control system to achieve real-time, reliable data communications to provide strongtechnical support.The system for the detection and control of diesel engine electronic control unit. CAN bus for datatransmission of various parameters of the diesel engine and user-friendly form color LCD screen tocarry out the appropriate display and built-in web server so that staff can be a convenient system forreal-time monitoring through the PC.
