射频识别 (RFID) 是广泛使用的最前沿技术之一，并且能够轻松地远距离跟踪物体，这使其在其他自动识别系统中具有优势。 RFID系统多年来一直用于动物识别和跟踪，最近被用于跟踪瘤胃中的数据（例如pH和温度）。问题之一是当该设备在瘤胃内使用时，身体组织会减弱信号。在这项研究中，我们尝试模拟用作 pH 丸剂的 RFID 标签的 UHF 信号在从动物体内出来后如何减弱。首选 RFID 标签工作频率为 434 MHz (UHF)，CST 模拟通过实际测量进行验证。动物左侧的信号更强，因为动物左侧的组织量少于其他两侧。最弱的信号是在器官密集的右侧采集的。
Radio frequency identification (RFID) is one of the forefronts of technologies that have found widespread use and the ability to track objects easily from a distance, make it advantageous within other automatic identification systems. RFID systems, which have been used for many years in animal identification and follow-up, have recently been used to track the data (such as pH and temperature) in the rumen. One of the problem is body tissues weakens the signal when the device is used inside the rumen. In this study, we tried to model how UHF signals of RFID tags used as pH bolus weaken after it comes out of the inner body of animal. Preferred RFID tags are operating at 434 MHz (UHF) and CST simulations are verified by real measurements. The signal is taken stronger at the left side of the animal because the amount of tissue on the left side of the animal is less than other sides. The weakest signals are taken at right side with dense organs.
