Can Bus-based Data Acquisition And Control System

The turbine simulator developed by SMU adopts industry computer and data acquisition card to complete data acquisition .data processing and control which takes excellent effectiveness in the simulation of the ship automation. Recently, in the process of researching the simulation system of power pulsion, it requires simulation platform to interpret and deduce the mathematical model of the ship power pulsion system quickly. The traditional data acquisition and control system based on industry computer has complex circuit and bad reliability. This subject is a part of power pulsion simulation system .It can completely resolve the problem in the traditional data acquisition and control system to develop the data acquisiton and control system based on CAN bus.Now microcontroller and field bus is not used frequently in the data acquisiton and control of the ship automation simulation system.lt is in the seaching stage.ln some industry monitor system, taking microcontroller and field bus to complete data acquisition and control does not realize the control funtion truly.Developing and researching this side will make up the blank of the application of the microcontroller and field bus in the simulaiton system of the ship automation control.Tht main content of this text is to develop the data acquisiton and control system based on CAN bus. ATmega128 mainly completes data acquisiton.data process.control operation, control output and so on;It realizes the CAN communication of intelligent node point and the host computer and the CAN communication between the intelligent node points to embed the application layer of CAN to ATmega128.The main develop work is as follows:1. hardware circuit design and debug...
