The motor driving circuit of the full-digital motor traveler with 80C196 single-chip computer as the core is developed, and the full-digital motor is studied.

Summary: The design process of deep-sea measurement and control system based on CAN bus with SJA1000 controller of PHILIPS company as the core is discussed. The performance requirements, composition, hardware connection and software design of the measurement and control system are described in detail around C8051F020 single-chip computer and SJA1000 controller. The system has the advantages of simple structure, low price and reliability.

Introduction Boiler is an important equipment to heat energy and power by burning heated working substances, and it is also a special equipment which is pressure-bearing, fire, explosive and widely used in all walks of life. Therefore, it is very important to monitor the operation status of the boiler in real time and find out the accidents in the operation of the boiler timely and accurately. The traditional boiler monitoring system has a lot of defects in measurement means and sensors used.

CAN (Controller AreaNetwork) is the controller local area network. CAN bus is one of the most widely used Fieldbus in the world. It was first introduced by Bosch Corporation in Germany. CAN communication protocol is a data communication protocol used between internal measurement and execution parts of automobiles. As an advanced technology, high reliability, complete function

Summary: The application of CAN bus in remote communication or self-organizing network of 232 serial devices is described, and the design method of hardware and software for CAN to RS-232 conversion device is introduced. The settings of CAN baud rate, automatic detection of serial baud rate and data flow control in software design are described in detail.
