LoRa網路架構下建置單車車隊路徑追蹤系統
A Tracking System for Cycling Team based on LoRa
摘要
近年來單車運動越來越流行，以往單車隊員只能依靠無線電或行動網路與領騎通訊，因為無線電無法定位，行動網路訊號可能較差，在較偏遠的地方發生意外時可能無法第一時間獲得救援，本研究實作一個以LoRa建置單車車隊路徑追蹤系統，領騎(LoRa Gateway)能接收單車車隊隊員的位置(LoRa模組)，以Google Map顯示每個單車騎士現在所在的位置，使領騎能夠掌握單車車隊隊員的絕對位置。 本實驗騎乘速度每小時約12公里，測試路程來回約10.5公里，單車路徑追蹤實驗結果，發送封包時間間隔為5秒時，封包接收成平均功率約68.3%，發送封包時間間隔為25秒時，封包接收平均成功率約92.2%，透過LoRa傳輸隊員經緯度資訊，領騎(LoRa Gateway)可精準顯示目前隊員所在位置，本實驗結論LoRa相較於目前無線感測器(WiFi、藍牙)更適合用於單車車隊路徑追蹤。

Cycling is one of healthy of exercises for the body to become a popular sport in the world. Traditional tools like walkie-talkies or handheld transceiver require to take one hand off the handlebars to communicate with the leader of cycling when you are cycling. In this study, we combined LoRa (Long Range) and Global Positioning System to construct a tracking system to calculate each member position for cycling team when they are moving. The distance of round-trip and the cycling rate is about 10.5 kilometers and 12 kilometers per hour, respectively. The results show that the packet delivery rate of accuracy is 92.2% and 68.3% in the transmission rate of 25 packets and 5 packets per second, respectively.
