MCRF355和MCRF360是13.56MHz的射频标记器件,它通过检出来自谐振天线线圈中信号而从询问机取得能量。在不断接收能量的过程中,它们发送出一个代码调制的信号串,其中以围绕100毫秒随机变化的静寂区间为间隔(参见附图)。 静寂区间使询问机有机会区分来自多个芯片的信号。因此,在一个箱中的物品可以使用标记而不必用条形码。这样一来,阅读机无需开箱便能一一 The MCRF355 and MCRF360 are 13.56MHz RF tag devices that extract energy from the interrogator by detecting signals from the resonant antenna coil. During constant reception of energy, they send out a code-modulated signal train with intervals of silence that randomly vary around 100 milliseconds (see the figure). Quiet intervals give the interrogator the opportunity to distinguish signals from multiple chips. Therefore, items in a box can use tags instead of barcodes. As a result, readers do not need to be out of the box
