LF, HF, UHF都分别代表什么
LF, HF, UHF都分别代表什么和我们听的收音机道理一样,射频标签和阅读器也要调制到相同的频率才能工作。
LF,HF,UHF 就对应着不同频率的射频。
LF代表低频射频,在125KHz左右,HF代表高频射频,在左右,UHF代表超高频射频,在860至960MHz范围之内。
对一个RFID系统来说,它的频段概念是指读写器通过天线发送、接收并识读的标签信号频率范围。
从应用概念来说,射频标签的工作频率也就是射频识别系统的工作频率,直接决定系统应用的各方面特性。
在RFID系统中,系统工作就像我们平时收听调频广播一样,射频标签和读写器也要调制到相同的频率才能工作。
射频标签的工作频率不仅决定着射频识别系统工作原理(电感耦合还是电磁耦合)、识别距离,还决定着射频标签及读写器实现的难易程度和设备成本。
RFID应用占据的频段或频点在国际上有公认的划分,即位于ISM波段。
典型的工作频率有:125kHz、133kHz、、、433MHz、902MHz~928MHz、、等。
按照工作频率的不同,RFID标签可以分为低频(LF)、高频(HF)、超高频(UHF)和微波等不同种类。
不同频段的RFID工作原理不同,LF和HF频段RFID电子标签一般采用电磁耦合原理,而UHF及微波频段的RFID一般采用电磁发射原理。
目前国际上广泛采用的频率分布于4种波段,低频(125KHz)、高频()、超高频(850MHz~910MFz)和微波()。
每一种频率都有它的特点,被用在不同的领域,因此要正确使用就要先选择合适的频率。
低频段射频标签,简称为低频标签,其工作频率范围为30kHz~300kHz。
典型工作频率有125KHz 和133KHz。
低频标签一般为无源标签,其工作能量通过电感耦合方式从阅读器耦合线圈的辐射近场中获得。
低频标签与阅读器之间传送数据时,低频标签需位于阅读器天线辐射的近场区内。
低频标签的阅读距离一般情况下小于1米。
低频标签的典型应用有:动物识别、容器识别、工具识别、电子闭锁防盗(带有内置应答器的汽车钥匙)等。

Vertical and horizontal mountable parts are available. These low profile Versatile Link packages are stackable and are enclosed to provide a dust resistant seal. Snap action simplex, simplex latching, duplex, and duplex latching connectors are offered with simplex or duplex cables.Package OrientationPerformance and pinouts for the vertical and horizontal packages are identical. To provide additional attachment support for the vertical Versatile Link housing, the designer has the option of using a self-tapping screw through a printed circuit board into a mounting hole at the bottom of the package. For most applications this is not necessary .Package Housing ColorVersatile Link components and simplex connectors are color coded to eliminate confusion when making connections. Receivers are blue and transmitters are gray, except for the HFBR-15X3 transmitter, which is black.Link Selection Guide(Links specified from 0 to 70°C, for plastic optical fiber unless specified.)Signal Rate Distance (m) 25°C Distance (m)TransmitterReceiver 40 kBd 120110HFBR-1523HFBR-25231 MBd 2010HFBR-1524HFBR-25241 MBd 5545HFBR-1522HFBR-25225 Mbd 3020HFBR-1521HFBR-2521HandlingVersatile Link components are auto-insertable. When wave soldering is performed with Versatile Link components, the optical port plug should be left in to prevent contamination of the port. Do not use reflow solder processes (i.e., infrared reflow or vapor-phase reflow). Nonhalogenated water soluble fluxes (i.e., 0% chloride), not rosin based fluxes, are recom-mended for use with Versatile Link components. Versatile Link components are moisture sensitive devices and are shipped in a moisture sealed bag. If the components are exposed to air for an extended period of time, they may require a baking step before the soldering process. Refer to the special labeling on the shipping tube for details.Recommended Chemicals for Cleaning/Degreasing Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane, heptane, Other: soap solution, naphtha.18.8 0.7407.6 (0.30)Do not use partially halogenated hydrocarbons such as1,1.1 trichloroethane, ketones such as MEK, acetone,chloroform, ethyl acetate, methylene dichloride, phenol,methylene chloride, or N-methylpyrolldone. Also, Avagodoes not recommend the use of cleaners that usehalogenated hydrocarbons because of their potentialenvironmental harm.Mechanical DimensionsHorizontal Modules Vertical ModulesVersatile Link Printed Board Layout DimensionsHorizontal Module Vertical Module Interlocked (Stacked) Assemblies (refer to Figure 1)Horizontal packages may be stacked by placing units with pins facing upward. Initially engage the inter-locking mechanism by sliding the L bracket body from above into the L slot body of the lower package. Use a straight edge, such as a ruler, to bring all stacked units into uniform alignment. This technique prevents potential harm that could occur to fingers and hands of assemblers from the package pins. Stacked horizontal packages can be disengaged if necessary. Repeated stacking and unstacking causes no damage to individual units.To stack vertical packages, hold one unit in each hand, with the pins facing away and the optical ports on the bottom. Slide the L bracket unit into the L slot unit. The straight edge used for horizontal package alignment is not needed.Stacking Horizontal ModulesFigure 1.

豪爵vf125说明书
豪爵vf125说明书原先两侧的黄色反光板已经被替换为LED牌照灯,联动原车日行灯,覆盖范围90度,配合大灯罩内的LED日行灯警示效果很好。
原车的35W欧司朗卤素灯几乎就是个蜡烛,当然我完全理解一些朋友说那个亮度足够使用,因为他们晚上骑得不快,视力也相对较好,对于我这种有点近视加散光的人来说那点亮度是在危险。
这个35W的LED小透镜安装调整好后切线干净左低右平不会晃到对方司机的眼睛,缺点是远光比较差劲,遇到远光狗不能很好的提示对方。
此类小透镜都是一样的,只要不是便宜的离谱都很耐用,原车插头直接插上无损安装,方法和VF100几乎一模一样无痕测车-VF100改灯。
原车闪光器在仪表旁边需要拆开面罩才能替换,如果不换闪光器直接改灯需要注意灯泡的功率,最好每个灯泡的功率在7瓦以上12瓦一下,如果使用双闪功能则四个灯泡的总功率不超过40瓦。
转向灯泡是个坑,也许你永远用不坏也许你刚装上就坏,功率太大会导致闪光器光速报废,功率太小闪光器将不会工作。
双闪加转向的开关是公模件,需要配一个转接线才能正常使用,安装很简单。
可能是我安装了风挡的原因本地几个车友也觉得比例出奇的协调,加上平时几乎没有带人的需求尾箱在不影响坐垫开合的前提下几乎就是挨着坐垫固定。
尾箱装车后双手离把车不抖,后座的人靠在靠背上很稳,但因为安装位置侵占了很多后座空间所以推荐安装在略靠后的位置上,这样也就不需要切割货架的后扶手。
155元的价格说实话很贵,而且自带的两个支架固定螺丝质量太差,强烈建议各位有想法的朋友自己买两颗正儿八经的304不锈钢螺丝,规格M6-100。
这玩意有两个好处,一是护着手,二个就是冬天不需要戴太厚的保暖手套,因为风不会吹在手上所以手部失温的速度会很慢。
总体安装简单调整不难,南方的朋友除非很强调安全不然没什么安装的必要性。
风挡在南方似乎也没什么必要,但我这里春秋天的晚上就能冻si个人。
无须太高,脖子以下不直接迎风即可,太高影响视线降低操控增加油耗得不偿失。
