物聯網架構下無線感測網路應用— 以冷鏈物流為例

Abstract

物聯網(Internet of Things, IOT)於近年來被國家與企業重視，其應用範圍涵蓋如交通、醫療、物流管理、安全管理、電力等各產業，其中無線感測網路為發展物聯網之關鍵技術之一，偵測周遭環境的溫度、濕度、光照等參數，定時紀錄與回傳這些資訊給監控者，幫助監控者做出最快速的判斷與錯誤修正。 將無線感測網路導入物流(Logistics)過程中，由其在冷鏈(Cold Chain)儲藏與運輸環節，有助於冷鏈物流業者掌控溫度與濕度等重要參數，確保冷凍、冷藏食品從產地到消費者手能做好適當的溫溼度掌控，避免造成食品發生異常而導致食物中毒等事件，因此食品如何藉由冷鏈控管而保障品質也備受重視。 因此本研究以個案訪談的方式，瞭解無線感測網路導入冷鏈儲藏與運輸環節後能自動監測與回傳通報環境溫濕度資訊至後台系統，改善以往人工監視與紀錄的成本與缺失。且因即時監控溫濕度資訊，方便企業在食品發生腐壞的當下馬上作出處理，減少貨品腐壞造成之成本問題。最後，能幫助企業追溯產品腐壞的時間點，釐清相關的賠償與法律責任。

The Internet of Things, IOT, is viewed as much important topic in recent years by the enterprises and countries. The scope of application includes various industries such as transport, medical, logistics management, security management, and electric. However, Wireless Sensor Network, WSN, is one of the key technologies to develop the applications of IOT. It can be used to measure the environment temperature, humidity, light and other parameters around the equipment and return all information of parameters to those monitors periodically. Finally, helping monitors make judgment and solve the problem. Using Wireless Sensor Network into the process of logistics, especially in the process of cold chain storage and distribution, help the dealer in cold chain logistics to ensure cold or frozen storage food to be treated in a good parameters control from the place of production to customers by controlling important parameters such as temperature and humidity, and prevent food from spoiling and poisoning event. Therefore, how to ensure the quality of food by controlling of cold chain logistics will be an important topic. In this study, knowing to use Wireless Sensor Network into the process of cold chain storage and distribution will measure and then return back the information of environment temperature and humidity to the system automatically , so it can improve the drawbacks derived from measuring and recording by human. However, Because of measuring temperature and humidity immediately, enterprises can deal with the problem immediately when food spoiling and decrease the cost derived from food spoiling. Finally, Wireless Sensor Network helps enterprises trace back to time of food spoiling and clarify related compensation and liability.
