停車格的可用性資料對於有效率的停車位偵測系統是很重要的,目前已經開發的室外停車系統是使用無線感測器、物聯網科技、及照相機組成的,但由於電磁場的干擾會使得調校偵測演算法變得複雜且使準確率只能有九成。在此研究中,我們利用磁力感測器、亮度感測器以及 LoRa 無線模組經由長達 13 個月的時間來感測車輛的暫態事件 (停車及開車) 來研究干擾的因素。藉由長期實地的實驗使得此停車位偵測系統在設置時只需要簡單的調校即可。
Data pertaining to the availability of parking slots is crucial to the efficientoperation of systems designed to monitor the state of parking spaces. Outdoorparking systems have been developed using wireless sensors, Internet of Things (IoT)technology, and cameras. Unfortunately, interference from electromagnetic fieldscomplicates the tuning of parameters for detection algorithms and limits accuracy to only 90 percent. In this study, we investigated these problems by collecting data from magnetic sensors, light sensors, and LoRa wireless modules used in the detection transient events (car arrivals and departures) over a period of 13 months.
This led to the design an adaptive occupancy detection system using a variety of
sensors, which can be deployed with only minimal calibration.
