碩士 === 正修科技大學 === 電子工程研究所 === 100 === The Controller Area Network (CAN) is based on a non-destructive arbitration mechanism to ensure that high priority delay-free transmission. It is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer so that the requirements of installation simplification, line simplification, high security, and network set up convenient, easy and inexpensive to maintenance can be achieved. It also can be adapted to the harsh environment of noise and pulse interference and can be used in wide area control sites. This research utilize independent CAN bus communication interface components which meet CAN 2.0B, ISO 11898 specification compliance agreement to design a Terminal Control Experiment System that equip with USB 2.0 transmission capacity and integrate with eight experimental modules; RFID system of peripheral devices, RF communications infrastructure, electronic compass, accelerometer sensor, temperature and humidity sensor, tire pressure detection, carbon monoxide detection and motor drives. The experiment contains CAN 2.0B bus multi-node links and automatic debugging detection mode, USB described in the definition and computer interface management, TTCAN (Time Triggered CAN) control integrate multiple sensing and driving experiments. Programmable control window of process management was applied through the experiment to increase operability and future development potential. The system is designed to be small size, low cost and can be randomly installed an experiment modules in the CAN bus. The advantages of USB 2.0 supports Full speed hot plug features for terminal monitor make any node module can execute terminal monitoring or information transfer tasks. It also designs to expand with RS232, SPI, I2C and other common peripheral device communication protocol, so it can be more flexible to changes in experimental.
