應用智慧型手機在摩托車事故時自動偵測系統
An automatic motorcycle accident detecting system by using smartphones
摘要
本論文提出了一種自動摩托車事故偵測系統以一般常見的智慧型手機採用Android系統，藉由它內部的加速度感測器，來偵測摩托車事故。當它偵測到使用者有極高的機率發生了摩托車事故，它會立即報告給管理中心或是指定的聯絡人,及時派遣及救單位。事故地點的GPS座標，將會被傳送給急救單位，以利救援單位盡快地抵達該事故地點。 我們提出的方法可分為三個部分。它們是：“摩托車事故檢測系統”和“設計無附件的演算法”最後是“模擬和結果”。在第一部分，藉由使用加速度感測器在Android平台上偵測G力（加速度）的過程，並根據加速度感測器的變化，它會檢測是否有摩托車事故發生。在第二部分中，我們將提出一個建立在智慧型手機平台的無附件檢測演算法。我們會把它與我們的模擬作結合。最後，在第三部分，我們將提出G力模式，我們實現了一個原型系統在Android系統的智能手機上，並進行大量的模擬，以評估我們的系統。 我們所提出的系統有下列幾點貢獻: 1.由於使用高成長速度的Android系統手機，人們容易獲得此應用程序。 2.使傷患在事故之後能立即被發現與救援。 3.減少在發生的摩托車事故與派遣急救單位之間的時間延遲。 4.人們不用購買摩托車事故偵測儀器，所以此系統可以避免額外的花費。

This thesis proposes an automatic motorcycle accident detecting system with the general common smartphones using Android system to determine motorcycle accident by its accelerometer sensor inside. When it detects that the user is extremely high probability for the motorcycle accident, immediately the system will report to the management center or designated contact people, dispatching promptly first responders. The GPS coordinates of the accident site will be transmitted to the rescue units to help them arrive at the accident site as quickly as possible. Our proposed method can be divided into three parts. They are: “Motorcycle Accident Detecting System”, “Algorithm Design without Accessory”, and “Simulations and Results”. In the first part, by using the accelerometer sensor in the Android platform to detect g-force (acceleration) experience, and based on the accelerometer sensor changes, then it detects whether the motorcycle accident occur or not. In the second part, we will present a detection algorithm based on the smartphone platforms without accessories. We will combine it with our simulations. Finally, in the third part, we will present g-force modes, and we will implement a prototype system on the Android system smartphone and we will conduct extensive simulations to evaluate our system. The proposed system has the following contributions: (1)Because of high using growth rate of Android system phones, that people easy access to this application. (2)Let injuries immediately to be found and rescued after an accident. (3)Decreasing the time delay between occurred motorcycle accident with the first responder dispatching. (4)People don’t need to buy motorcycle accident detecting machines, so the system can avoid additional costing.
