碩士 === 桃園創新技術學院 === 機械工程系機械與機電工程碩士班 === 104 === This research is to develop a car door opening safety protection system with serial communication that can be conveniently applied on common vehicles. The system is consist of a wheel speed sensor, a gear switch, a door opening sensor, a seat belt sensor, an audio and speaker unit, a rearview mirror camera and a video displayer, a LED moving warning lamp, RS-232 serial communication and 8051 single-chip, and can be refitted or optionally installed on common vehicles. While the system operating will lock the door for 3 to 5 seconds and play a warning sound to remind the passenger who is going to get off the car, On the other hand, the serial communication to the LED moving warning lamp on the rear windshield, reminds the vehicle driver from behind by the LED warns the action of door opening, both methods are adopted to avoid the endless door opening traffic accidents. The system uses an original self-creation sound module, rearview mirror camera and video displayer, LED moving warning lamp and RS-232 serial communication skill, and let the rear LED moving warning lamp can showing the forward/back, stop, turn right and left and door opening etc. ,of the car operation information by two signal line. This is not only achieving the goal of research, but also greatly reducing the amount and cost of the wire. The system has very good effect on warning or avoiding car accidents whether the car passenger or the car from behind. Therefore it has great commercial value and it has applied for a national patent.
