隨著網路及科技發達精進,人們不必出門即可於網路上訂購物品,並且能送貨到家,但於貨物運送之過程中,有時因人為(如重摔、拆封等)而導致物品破損,物聯網能夠為物流產業邁入全新的管理方式,使物流產業於運輸過程中確保貨物之安全性,本研究利用力量感測器、後端訊號處理系統與車用娛樂資訊系統(車載機)結合物連網之相互作用,實現物流之智能化與網路化。而本研究開發以三明治貼合方式製作之貼片式壓電力量感測器 - 拉力感測器及衝擊感測器,兩種感測器的差別為內層有無鋼體結構;首先,感測器以標準校正平台進行檢驗,於貼片式壓電拉力感測器與貼片式壓電衝擊感測器之表面分別施加相同2牛頓正向力量,以進行觀察感測元件壓電薄膜施壓時輸出之壓電訊號誤差範圍,若感測器之訊號範圍超過誤差範圍則不予採用,以此平台確保感測器之穩定性;爾後,第一種實驗透過貼片式壓電拉力感測器以膠帶黏貼於貨箱之上方,針對不同速度與角度之量測;第二種實驗為了模擬物品由高處掉落造成損壞之情境,貼片式壓電衝擊感測器黏貼於貨箱下方進行自由落體測試,針對不同重量之量測,藉由第一種實驗與第二種實驗分別量測壓電薄膜受彎曲應力及受到貨箱衝擊力量而產生壓電訊號,並以示波器設備與車用娛樂資訊系統擷取訊號及觀察其變化;最後,為模擬貨箱於貨車行駛中感測器訊號之變化,將衝擊感測器結合後端電路處理系統後放於車子,量測車輛行駛時之震動對於不同封裝層厚度之感測器電壓訊號產生的情形。本研究實現貼片式壓電力量感測器應用於物流即時監測系統,該系統能夠協助物流業者降低貨品遞送過程之貨品毀損與遺失率,可即時偵測貨品於運送過程之不當碰撞與封裝膠帶之事件,爾後,將貨物資訊上傳至雲端資料庫做數據分析。

關鍵字:貼片式壓電力量感測器、PVDF、物流、衝擊力量。

We propose the use of simple and low cost piezoelectric based patch type force sensors that ensure safety of the package while also detecting damage during shipment. A patch type tear off sensor is taped to the top of the package. When the package is opened by removing the tape, a tensile stress is exerted on the piezoelectric polyvinylidene fluoride (PVDF) film. A patch type impact sensor is taped to the bottom of the package. It consists of miniaturized ferrous balls attached to a PVDF film and is used to detect damage due to compressive stress exerted during impact. The sensors are connected to a low power prototype read out device that is also attached to the package and consists of a microcontroller (MCU) unit to analyze the data and a Bluetooth module to transfer the data wirelessly. We have shown the viability of having an on-vehicle telematics device for collecting and analyzing data from multiple packages wirelessly so that it can be uploaded to the cloud, thus allowing for real time monitoring during transport. This logistics management model based on Internet of Things (IOT) would aid in improving the quality of services provided by the logistics company while also earning consumer credibility. Thus, we believe that these patch type force sensors can be realistically implemented in logistics in the near future

Keywords: Piezoelectric patch type force sensor、Logistics、Real time monitoring、PVDF.
