It can also be sent to different alarm devices or mobile phones via wireless communication (RF/Bluetooth/Z-wave/GSM/CDMA/WiFi/WiMAX/ZigBee).
方案工作原理：  How the program works:
尿液或水份 (对比其他的固态物质，如纸尿片）具很高的介电常数,会非常影响 RFID讯号。 水份对 RFID标签的影响， 一向被视为不确定因素。 因此,在许多 RFID系统中,都会保护 RFID 标签附近不会存在过高的水份。  Urine or water (compared to other solid materials, such as diapers) has a high dielectric constant that can greatly affect the RFID signal. The impact of moisture on RFID tags has always been considered an uncertain factor. Therefore, in many RFID systems, there is no excessive moisture in the vicinity of the RFID tag.
而在本发明中， 则相反地利用了 RFID标签的这种特性。 在 RFID标签的设计中,采用了 co-design approach , 即把标签附近的空间， 在 RFID标签的设计中， 也当成标签的一部份去考 虑。 因此， 当在这空间内的湿度出现变化时。 RFID标签的一些参数,如阻抗,如阻抗,会随之改 变。  In the present invention, however, this characteristic of the RFID tag is utilized in reverse. In the design of RFID tags, the co-design approach is adopted, that is, the space near the tag is also considered as part of the tag in the design of the RFID tag. Therefore, when the humidity in this space changes. Some parameters of the RFID tag, such as impedance, such as impedance, will change.
其中, RFID标签的阻抗的改变,对 RFID标签与 RFID阅读器之间的配对尤其重要。 不同的 RFID标签的设计对湿度变化的反应亦不同。 因此， 可以根据需求,让 RFID标签在高于或低于 某一湿度水平时,才被阅读器读到。 Among them, the change of the impedance of the RFID tag is particularly important for the pairing between the RFID tag and the RFID reader. The design of different RFID tags also reacts differently to changes in humidity. Therefore, the RFID tag can be made higher or lower according to the demand. At a certain humidity level, it is read by the reader.
原则上， 只需一个 RFID标签就可分辨纸尿产品有没有尿湿。 但更多的 RFID标签,可以 确保其准确性。 在发明中,纸尿产品上的 RFID标签的数量可能为 1-N  In principle, it is only necessary to have an RFID tag to distinguish whether the urine product is wet or not. But more RFID tags can ensure their accuracy. In the invention, the number of RFID tags on the urine product may be 1-N.
其中， N为自然数。 在产品中 ,Ν的优选为 2  Where N is a natural number. In the product, the preferred value of bismuth is 2
而两个 RFID标签的设计不同， 一个在湿度高时被 RFID阅读器读到,湿度低时读不到,另 一个设计则相反， 在湿度低时被 RFID阅读器读到， 湿度高时读不到。  The design of the two RFID tags is different. One is read by the RFID reader when the humidity is high. When the humidity is low, the other design is reversed. When the humidity is low, it is read by the RFID reader. When the humidity is high, the reading is not high. To.
这个组合能确保不论湿度高或低的时候， RFID 阅读器都可以从纸尿产品读到回传的讯 息。 RFID 阅读器将读到的数据传送到系统分析。 系统能从中知道纸尿产品中尿湿的情况。 当湿度超过某一限制时，会启动报警系统。  This combination ensures that RFID readers can read back information from the urine product regardless of whether the humidity is high or low. The RFID reader transmits the read data to the system analysis. The system can know the wetness of the urine in the paper urine product. When the humidity exceeds a certain limit, the alarm system is activated.
报警系统的方案主要可分为两种：  The scheme of the alarm system can be mainly divided into two types:
1. 手提式报警装置  Portable alarm device
RFID 阅读器及报警系统嵌入在一手提报警装置。 手提报警装置的配带者可直接监察附 近的纸尿产品的状况， 并直接发出报警。  The RFID reader and alarm system are embedded in a hand-held alarm device. The wearer of the portable alarm device can directly monitor the condition of the nearby urine product and issue an alarm directly.
