串列傳輸應用於車門開啟安全防護系統之研製

本研究旨在研製一組可應用於一般車輛的串列傳輸車門開啟安全防護系統，該系統以音效模組、開門感知器、安全帶感知器、排檔感知器、輪速感知器、照後鏡攝影機/顯示幕、LED 動態圖形警示燈、串列通訊與8051 單晶片等構成，可加裝或選配於一般車輛上。當使用者有一連串的下車動作時，系統的單晶片微電腦會自動將車門扣住不開3 到5 秒，同時一方面發出警示音效提醒車內欲下車者注意後方來車，另一方面也透過串列傳輸給車後檔風玻璃或飾板上的LED 動態圖形警示燈顯示開門中的警示符號，提醒車外的後方來車駕駛，如此雙管齊下，避免層出不窮的開門車禍發生。本系統使用獨創的音效模組、照後鏡攝影機/顯示幕、LED 動態圖形警示燈與串列傳輸技術，讓車子的前進/後退、停止、左右轉及開車門等多重資訊可以僅靠兩條信號線傳遞與控制後方的LED 動態圖形警示燈顯示相應訊息，不僅達成研發功能，也大大減少線材的用量與成本。

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, 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 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.
