说明:  装置中阅读器、应答器均有无线传输汉字的功能,载波频率≤5MHz,调制方式任选。不得使用现有射频识别卡或用于识别的专用芯片。装置中的耦合线圈为圆形空芯线圈,用直径不大于1mm的漆包线或有绝缘外皮的导线密绕10圈制成。线圈直径为6.6±0.5cm(可用直径6.6 cm左右的易拉罐作为骨架,绕好取下,用绝缘胶带固定即可)。线圈间的介质为空气。两个耦合线圈最接近部分的间距定义为D。 阅读器、应答器只能使用耦合线圈耦合,不得使用其他耦合方式。 阅读器采用外接单电源供电,具有通过无线方式实现“写”与“读”汉字的两种工作模式,由开关或键盘实现 “写”或“读”的控制。“写”状态,输入用键盘,并有显示屏显示输入的汉字。“读”状态,显示屏显示应答器接收的汉字。 应答器供电要求有两种方式,一是采用两节1.5V,5号干电池供电,另一是通过耦合线圈由阅读器无线方式提供。应答器能够通过无线方式接收、存储由阅读器传来的预置汉字信息(或编码),装置断电后,应答器存储的信息不丢失。应答器能通过无线方式读出由阅读器传输来的汉字。应答器还应设有对写入汉字信息进行擦除的功能键。 预置汉字范围为二级汉字或液晶显示器汉字库范围。
(Devices, reader, transponder features of Chinese characters have a wireless transmission, carrier frequency ≤ 5MHz, modulation optional. Shall not use the existing radio frequency identification cards or used to identify a dedicated chip. The coupling device for a circular coil air-core coils, with diameters less than 1mm of the enameled wire or wire insulation jacket made of dense around the 10 laps. Coil diameter of 6.6 ± 0.5cm (about 6.6 cm in diameter can be used cans as a skeleton around the well removed, can be fixed with insulating tape). The medium is air between the coils. Two coupling coils closest to the part of the pitch is defined as D. Reader, can only use the transponder coupling coil coupling shall not be used in other coupling methods. Reader with a single external power supply, with a wireless way to achieve "write" and "reading" Chinese characters are two kinds of working mode switch or the keyboard to achieve by the "write" or "read" control. "Write" state, inpu)
