摘要:
RFID tag and a system and method involving a plurality of RFID tags. Each RFID tag is attached to an object on which the presence of a predefined fluid is monitored. In a first state, (absence of the monitored fluid), the tag acts as a passive RFID tag, and the information it holds can be read with a proximity reader. This operation is performed when the RFID tag is attached to the object to be monitored. In a second state, whenever the monitored fluid appears on the tagged object, a fluid activated battery generates the electrical power which is used to power the RFID tag. The RFID tag then acts as an active RFID tag and starts to emit messages which can be received by a RFID reader.
摘要(中):
RFID标签和涉及多个RFID标签的系统和方法。 每个RFID标签连接到其上监视预定流体的存在的对象。 在第一状态(不存在被监视的流体)的情况下,标签用作无源RFID标签,并且可以用邻近读取器读取其保存的信息。 当RFID标签附着到被监视对象时,执行该操作。 在第二状态下,每当被监视的流体出现在被标记的物体上时,流体活化的电池产生用于为RFID标签供电的电力。 RFID标签然后用作有源RFID标签,并开始发射可由RFID读取器接收的消息。
