中文摘要 | 數位式行車紀錄可搭配GPS(全球定位系統),將行車資訊與路線加以記錄。由於記錄器所獲得的資訊都是離線(off-line)處理,無法即時監控車輛的動向,為達成即時(real-time)監控與處理行車動態資訊,與行動通訊技術之整合為一解決途徑。本論文中提出GPRS模組跟數位式行車紀錄器整合,透過電信網路方式將車上之動態訊息傳送到指定的網路接收端,並分析傳送端GPRS收訊與資料傳輸之間的關係。本論文以Siemens TC45 GPRS模組內建Java程式語言為開發平台,發送端程式配合實驗結果,設計出以不間斷連線的方式傳送資料,提高資料傳送的穩定性。 |
英文摘要 | A digital vehicle recorder (DVR) uses Global Positioning system (GPS) to obtain the position and route, and these data have been recorded in the memory of the DVR. A user downloads the data by USB flash disk, when status of the DVR is off-line. After the data is downloaded, they can be analyzed by post-processing tools. But the manager can't monitor these vehicles at this monent. The purpose of the paper is to combine the DVR and General Package Radio Service (GPRS) to accomplish the real-time vehicle information transmission. At transmitter side, the DVR uses Siemens TC45 GPRS module to transmit real-time information of the vehicle to the receiver through the GPRS network. The development platform is based on Java programming language. At receiver side, the user can obtain these data from DVR in on-line fashion. The system experiment of the proposed GPRS architecture is implemented to demonstrate the reliable connection between transmitter and receiver. |
