The Controller Area Network is based on a non-destructive arbitration mechanism to ensure 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 convenient network setup, easy and low maintenance cost 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 work utilizes independent CAN bus communication interface components which meet CAN 2.0B, ISO 11898 specification compliance agreement to design a Terminal Control Experiment System that is equip with USB 2.0 transmission capacity and is integrated with seven experimental modules; RFID system of peripheral devices, accelerometer sensor, temperature and humidity sensor, tire pressure detector, carbon monoxide detector 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 in size, low cost and experiment modules can be randomly attached to the CAN bus. The advantages of USB 2.0 includes supports for Full speed hot plug features terminal monitor allow any node module can execute terminal monitoring or information transfer tasks. It is also designs to be expand with RS232, SPI, I2C and other common peripheral device communication protocol, so it can be more flexible to changes in experiments.
