Description

一种可自动调整功耗的UHF读写器
技术领域
本发明涉及UHF读写器技术领域,具体涉及一种可自动调整功耗的UHF读写器。
背景技术
射频识别(RFID)是一种无线通信技术,可以通过无线电讯号识别特定目标并读写相关数据,而无需识别***与特定目标之间建立机械或者光学接触。无线电的信号是通过调成无线电频率的电磁场,把数据从附着在物品上的标签上传送出去,以自动辨识与追踪该物品。某些标签在识别时从识别器发出的电磁场中就可以得到能量,并不需要电池;也有标签本身拥有电源,并可以主动发出无线电波(调成无线电频率的电磁场)。标签包含了电子存储的信息,数米之内都可以识别。与条形码不同的是,射频标签不需要处在识别器视线之内,也可以嵌入被追踪物体之内。
许多行业都运用了射频识别技术。将标签附着在一辆正在生产中的汽车,厂方便可以追踪此车在生产线上的进度。仓库可以追踪药品的所在。射频标签也可以附于牲畜与宠物上,方便对牲畜与宠物的积极识别(积极识别意思是防止数只牲畜使用同一个身份)。射频识别的身份识别卡可以使员工得以进入锁住的建筑部分,汽车上的射频应答器也可以用来征收收费路段与停车场的费用。
但是现有的手持UHF读写器不能很好的调整运行功率,设备功耗偏大,待机时间较短。
发明内容
为解决上述问题,本发明采用以下技术方案:
一种可自动调整功耗的UHF读写器,包括UHF读写器模块,所述UHF读写器模块连接有功率调整电路,所述功率调整电路包括电源、控制器、射频功率放大器、天线,所述控制器、射频功率放大器、UHF读写器模块与电源电连接,所述控制器与UHF读写器模块通讯连接,所述射频功率放大器与天线电连接。
作为进一步说明的,所述控制器包括标签规模预估模块,所述标签规模预估模块通过标签的规模大小来调整UHF读写器模块的运行功率。
本发明与现有技术相比,具有以下优点:
本发明结构简单,通过控制器可以很好的根据需要调整运行功率,大大降低了功耗,提高了待机时间。
附图说明
图1是本发明的***框图示意图;
图2是本发明的标签规模预估模块控制模式示意图。
具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
在本发明的描述中,需要说明的是,术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。此外,术语“第一”、“第二”、“第三”仅用于描述目的,而不能理解为指示或暗示相对重要性。
在本发明的描述中,需要说明的是,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”应做广义理解,例如,可以是可变连接,也可以是可拆卸连接,或一体地 连接;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连,可以是两个元件内部的连通。对于本领域的普通技术人员而言,可以具体情况理解上述术语在本发明中的具体含义。
实施例:
如图1-2所示,一种可自动调整功耗的UHF读写器,包括UHF读写器模块,所述UHF读写器模块连接有功率调整电路,所述功率调整电路包括电源、控制器、射频功率放大器、天线,所述控制器、射频功率放大器、UHF读写器模块与电源电连接,所述控制器与UHF读写器模块通讯连接,所述射频功率放大器与天线电连接。
所述控制器包括标签规模预估模块,所述标签规模预估模块通过标签的规模大小来调整UHF读写器模块的运行功率。
具体使用时,UHF读写器模块的射频收发模块处理读写器与RFID芯片的数据通信,接收处理器主控模块的命令,根据命令对信息进行编码和调制,发送到RFID芯片中,并接收来自RFID芯片的载波信号,对该信号进行解调和解码,再根据控制器的标签规模预估模块的命令对接收的信号进行处理,具体处理如图2所示,通过预估标签规模,可以及时调整运行功率,减少功率的浪费,减少功耗,提高待机时间,提高使用效率。
本发明所作的举例,而并非对实施方式的限定。对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动,这里无需也无法对所有的实施方式予以穷举,而由此所引申出的显而易见的变化或变动仍处于本发明的保护范围中。
