Intelligent Monitoring System For Temperature And Coolant Level Of Slurry Pump Based On CAN Fieldbus Thchnology

Fieldbus Control System (FCS) is a new kind of control system after DCS. Compared with DCS, FCS realizes intercommunication between control station and field equipments and absolutely 'Disperse Control' . It is the development trend of autocontrol system, which becomes one of the important studying in the autocontrol system field in recent years. CAN-bus is a kind of field bus. It has remarkable advantages such as simply structure, fine real-time, high reliability, powerful anti-interference ability, and low cost, strong flexibility. CAN-bus is the only fieldbus with international standard at present.The thesis adopts the microcontroller MC9S12DJ128 with MSCAN made of Freescale and 1-wire temperature sensor build up intelligent FCS monitoring system.The paper consists of five parts:The first chapter is the introduction. From analyzing the slurry pump in industrial application and its job requirements. The paper describes the meaning, relevant research current situations and main research tasks of the subject and has summarized the relevant documents and materials.The second chapter details the structure and characteristics of CAN-bus with the aid of OSI model and analyses the development trend of CAN-bus in term of application.The next chapter is the emphases of the paper. It details the hardware design and soft design of the whole system by. It mainly includes the hardware and software design of temperature and level measuring module, alarming module, displaying module, supplying module and CAN communication interface module and so on.The forth chapter details the experiment scheme and the experiment result, analysis the experimental data, and draws a conclusion.The last chapter narrates seven main conclusions and experience that can...
