碩士 === 高苑科技大學 === 電機工程研究所 === 99 === In this thesis develops an intelligent pilot information system for electric bike, it integrated a safety system, a balanced tire pressure monitoring system and an anti-theft system. All of the messages are communicated through CAN-BUS network. The safety system is monitoring the front and both side of back of bicycle by ultrasonic ranging technology, simultaneously. It can detect front hazard on the ground. Tire pressure monitoring system monitor the tire pressure by detecting individual wheel rotational speeds, and compares each other. Because the bike’s tires are thin and vibrated due to un-flat road, thus the measured data are containing some uncertainty factors and not realized. Thus, we use the robust fuzzy modeling approach to implement the function between tire pressure ratio and rotational speed ratio by real measured data. Anti-theft system combines RFID, GPRS/GSM, GPS and gyro forms a dual-chip network security systems. A dual-chip security system includes two kinds of chip: SIM card and RFID tag. The host system will be not working and trigger the alarm system either the SIM card is not plugged in or the phone number does not match, or the RFID reader reads an unmatched UID code. The gyro system is used to supervise the bike’s attitude. When the bike parked outside, if the bike is moved and the detected angle exceeds a pre-defined value, then start the alarm system. Moreover, the bike position can be monitored by a host computer through network or sends a SMS to the user by using GPS, GSM/GPRS module combines E-map. Therefore, we can obtain the information of bike’s location immediately. Finally, all of the messages are send to MCU through CAN-bus. CAN-bus only uses two differential transmission lines and with high immunity noise ability. It can reduce wiring complexity.
