本研究的主要目的在利用較簡易的超音波感測器模組來進行障礙
物偵測, 尤指於道路行進時可能遭遇的物體. 我們藉由微處理機的控制,
以達到各個感測器模組可在同一時間內接收訊號的功能, 同時為了進一步
明瞭此種構想對於障礙物的偵測情形, 我們設計並製作了兩種測試硬體 :
.一套以微處理機為中央處理單元的獨立系統, 用以偵測障礙物並顯示所
測得之 距離, 並可裝置於一般汽車上以測試道路障礙物的反應
情形. .同樣以微處理機為中心的介面系統, 可將所收集之資料送
回所連結之主電腦以 進行整合判斷. 經由解譯所測得的
數據, 我們已可估計障礙物出現的距離與行進的概略方位, 同時也期待本
實驗與研究的結果可陸續做為自主導航車或行動機器人障礙物偵測及避免
的基礎.

The objective of this research is to detect the
obstacles, especiallyfor the on-road obstacles, by using the
less complicated ultrasonic sensormodules. All the sensor
modules can receive the ultrasonic signal simultaneouslythrough
the controlling of microprocessor. In order to inquire further
into thesituation of detection using the idea mentioned above,
two sets of testing hardware are designed and implemented. They
contain: .An independent circuit mainly constructed by
the microprocessor owns the capability to detect the
obstacles and display the distance. This device can be
also equipped on the car to detect the obstacles on the
road. .An interface card collects the data from all
sensor modules and sends them back to the host computer
for further processing. The estimation of distance and
location of obstacles has been achievedby interpreting the
measured data. These results of research may be the basis
ofobstacle detection and avoidance for the autonomous land
vehicle or mobile robot.
