Description

主动式高频电子标签Active high frequency electronic tag 发明领域Field of invention
本发明涉及主动式高频电子标签，具体涉及一种含有电池的高频电子标签，以提高射频传输距离。The invention relates to an active high-frequency electronic tag, in particular to a high-frequency electronic tag containing a battery to increase the radio frequency transmission distance.
背景技术Background technique
伴随着移动互联网普及，现代人外出只带手机即可。然而，仍然存在一些无法彻底整合的手机的服务。例如，需要额外芯片配合的近场通讯(Near-Field Communication，NFC)技术，通常只出现在2000元以上部分手机中，只有市场领先企业才有能力与各地公交集团进行合作，以全国交通一卡通为例，从2013年交通部建设一卡通清分结算平台开始，到2015年长春市发行国内首张一卡通，2019年接入全国260市、89县，却仍然存在部分城市、部分线路无法使用，例如：重庆主城区、杭州都没接入，上海、成都的地铁不可用，珠海部分公交不可用。这些未加入交通联合的城市定居用户，仍需购买实体交通卡。此外，加密门禁卡也无法通过NFC模拟。With the popularization of the mobile Internet, modern people only need to bring their mobile phones when they go out. However, there are still some mobile phone services that cannot be fully integrated. For example, the Near-Field Communication (NFC) technology that requires additional chips to cooperate is usually only found in some mobile phones above 2,000 yuan. Only market-leading companies have the ability to cooperate with local public transportation groups. For example, starting from the construction of the all-purpose card clearing and settlement platform by the Ministry of Communications in 2013, to the first domestic all-in-one card issued by Changchun City in 2015, it was connected to 260 cities and 89 counties across the country in 2019, but there are still some cities and some lines that cannot be used, such as: The main urban areas of Chongqing and Hangzhou are not connected. The subways in Shanghai and Chengdu are unavailable, and some buses in Zhuhai are unavailable. These urban settled users who have not joined the transportation union still need to purchase physical transportation cards. In addition, the encrypted access card cannot be simulated by NFC.
无论公交卡还是门禁卡，都利用了射频识别(Radio Frequency Identification，RFID)技术。第一个真正的现代RFID收费装置于1973年被授予专利，由外部射频提供能量，具备16位存储。RFID又被称为电子标签。在RFID发明出现的前20年，在全球范围内普及的是条形码，尽管RFID每次可读取上百个，而条码只能一次一读，但直到2010年RFID的应用才得到显著增加，归功于电子标签成本(2011年低至0.33元)下降、可靠性增加至99.9％。RFID通常由芯片和天线嵌入聚氯乙烯(Polyvinyl Chloride，PVC)封装以防水、避免物理损坏。Both the bus card and the access card use radio frequency identification (RFID) technology. The first truly modern RFID charging device was granted a patent in 1973. It is powered by an external radio frequency and has 16-bit storage. RFID is also called electronic tag. In the first 20 years of the invention of RFID, barcodes were popularized worldwide. Although RFID can read hundreds of barcodes at a time, and barcodes can only be read at a time, it was not until 2010 that the application of RFID increased significantly. As the cost of electronic tags (as low as RMB 0.33 in 2011) has decreased, the reliability has increased to 99.9%. RFID usually consists of a chip and antenna embedded in a polyvinyl chloride (PVC) encapsulation for waterproofing and avoiding physical damage.
常见交通卡、门禁卡(标准卡片尺寸85.5×54×0.76毫米)都不含电池，属于被动式RFID，包含了芯片和天线。芯片通过天线接收RFID读取器发出的电磁波获得能量，并回传相应的反向散射讯号至RFID读取器。Common transportation cards and access control cards (standard card size 85.5×54×0.76 mm) do not contain batteries and are passive RFID, including chips and antennas. The chip receives the electromagnetic waves emitted by the RFID reader through the antenna to obtain energy, and returns the corresponding backscatter signal to the RFID reader.
射频卡的外形尺寸主要由天线决定，而天线又取决于工作频率和对作用距离的要求。目前有4种频率的射频卡在使用中比较常见：低频(125或134.2kHz)、高频(13.56MHz)、超高频(868～956MHz)及微波(2.45GHz)。射频卡的频率越高，感应的距离就越大，数据传输率也就越高，识别标签的外形尺寸就可以做得更小，但成本也越高。The external dimensions of the radio frequency card are mainly determined by the antenna, which in turn depends on the working frequency and the requirements for the operating distance. There are currently 4 kinds of frequency radio frequency cards that are more common in use: low frequency (125 or 134.2kHz), high frequency (13.56MHz), ultra high frequency (868～956MHz) and microwave (2.45GHz). The higher the frequency of the radio frequency card, the greater the sensing distance, the higher the data transmission rate, and the size of the identification tag can be made smaller, but the cost is also higher.
汽车的无钥匙进入***(Remote Keyless Entry,RKE)，即为315MHz(北美)或433.9MHz(亚欧)主动式RFID，可通过内置电池驱动，随时主动发射数据到RFID读取器，又被称为有源电子标签。The car’s keyless entry system (Remote Keyless Entry, RKE), which is 315MHz (North America) or 433.9MHz (Asia-Europe) active RFID, can be driven by a built-in battery and actively transmit data to the RFID reader at any time, also known as It is an active electronic tag.
发明概述Summary of the invention
现有的门禁卡，使用起来相当繁琐，如果实现类似汽车的无钥匙进入***(RKE)体验会更好。基于天线测试数据，常见的13.56MHz高频卡，感应距离可达0.5米。这个距离并不充足，但可以通过天线优化。对于有些应用，更小的感应范围更好。譬如交通卡，如果多个闸机同时打开，还得通过软件优化，比如，只打开最近的(信号最强的)闸机，但老旧型号未必支持固件升级。The existing access control card is quite cumbersome to use, and it would be better if the keyless entry system (RKE) experience similar to a car is realized. Based on the antenna test data, the common 13.56MHz high-frequency card, the sensing distance can reach 0.5 meters. This distance is not sufficient, but it can be optimized by the antenna. For some applications, a smaller sensing range is better. For example, for a traffic card, if multiple turnstiles are opened at the same time, software optimization must be used. For example, only the nearest (strongest signal) turnstile can be opened, but the old models may not support firmware upgrades.
然而，应当理解，本发明内容可能不包含本发明的所有方面和实施例该发明内容并不意味着以任何方式进行限制或限制，并且本文公开的本发明将被下列之一理解：本领域普通技术人员包括对其的明显改进和修改。However, it should be understood that the content of the present invention may not include all aspects and embodiments of the present invention. The content of the present invention is not meant to be restricted or restricted in any way, and the present invention disclosed herein will be understood by one of the following: The technical staff includes obvious improvements and modifications.
具体实施方式Detailed ways
现在将在下文中更充分地描述本发明。然而，本发明可以以许多不同的形式实施，并且不应被解释为限于本文所阐述的实施例。但愿，提供这些实施例使得本公开将是彻底和完整的，并且将向本领域技术人员充分地传达本发明的范围。The present invention will now be described more fully hereinafter. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Hopefully, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.
应当理解，在不脱离所附权利要求书中阐述的精神和范围的情况下，可以对元件的功能和布置进行各种改变。因此，实施例是本发明的示例或实现，而不是唯一的实现。各种出现“一个实施例”，“实施例”或“一些实施例”不一定都指代相同的实施例。虽然可以在单个实施例的上下文中描述本发明的各种特征，但是特征也可以单独地或以任何合适的组合提供。相反的，尽管为了清楚起见，本文中可以在单独的实施例的上下文中描述本发明，但是本发明也可以在单个实施例或实施例的任何组合中实现。It should be understood that various changes can be made to the function and arrangement of elements without departing from the spirit and scope set forth in the appended claims. Therefore, the embodiments are examples or implementations of the present invention, rather than the only implementations. The various appearances of "one embodiment," "an embodiment," or "some embodiments" do not necessarily all refer to the same embodiment. Although various features of the invention may be described in the context of a single embodiment, the features may also be provided individually or in any suitable combination. Conversely, although the invention may be described herein in the context of separate embodiments for the sake of clarity, the invention may also be implemented in a single embodiment or any combination of embodiments.
除非另有定义，本文使用的所有术语(包括技术和科学术语)具有与本发明所属领域的普通技术人员通常理解的相同的含义。将进一步理解的是，诸如在通常使用的字典中定义的那些术语应当被解释为具有与它们在相关技术和本公开的上下文中的含义一致的含义，并且将不被解释为理想化的或过度正式的意义，除非本文中明确地这样定义。Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of related technologies and the present disclosure, and will not be interpreted as idealized or excessive The formal meaning, unless explicitly defined as such in this article.
参考术语如“上”、“下”、“左”、“右”、“底”、“侧”旨在用于在描绘本发明实施例中的具体特征，结构或元件的取向。显然，关于设备的实际使用的这种方向性术语没有特定的含义，因为设备可以由用户或多个用户在多个方向中使用。Reference terms such as "upper", "lower", "left", "right", "bottom", and "side" are intended to be used to describe the orientation of specific features, structures or elements in embodiments of the present invention. Obviously, such directional terms regarding the actual use of the device have no specific meaning, because the device can be used by a user or multiple users in multiple directions.
常见的13.56MHz高频卡(HF)，应用最为广泛，包含了交通卡、门禁卡、银行卡，因为价格便宜(2011年低至0.33元)，全球通用标准。超高频(UHF)可以获得更大读取范围，然而涉及到UHF读取器，这对于已有的基于高频卡设施，意味着大量升级成本，更实际的应用是通过内置电源、优化天线支持合适的感应范围。The common 13.56MHz high-frequency card (HF) is the most widely used, including transportation cards, access control cards, and bank cards, because the price is cheap (as low as 0.33 yuan in 2011) and is a universal standard. Ultra-high frequency (UHF) can achieve a larger reading range, but when it comes to UHF readers, this means a lot of upgrade costs for existing high-frequency card-based facilities. A more practical application is to optimize the antenna through the built-in power supply. Support suitable sensing range.
为了保证电池电力不足时本发明实施例能正常使用，除了针对特定应用合适感应范围专门优化的天线，也包含一个支持被动式射频卡的天线。In order to ensure that the embodiment of the present invention can be used normally when the battery power is insufficient, in addition to an antenna specially optimized for a suitable sensing range for a specific application, an antenna supporting a passive radio frequency card is also included.
电池可以设计为内置，也可以设计为可更换(譬如9号电池)。为节约电力、保证续航时长，可以设置电源开关，也可以内置定位***(比如GPS)确认用户在某个建筑物内(门禁卡)、车站(交通卡)、ATM机/银行(银行卡)再开启电源。如果现有的RFID读取器支持，也可以根据读取器信号，再切换待机/激活(开始发送射频)。如果用户需要频繁充电，就谈不上任何便利。此外也可以通过指示灯提示用户电量过低。The battery can be designed as built-in or replaceable (for example, AA battery). In order to save power and ensure long battery life, you can set a power switch, or a built-in positioning system (such as GPS) can confirm that the user is in a building (access card), station (traffic card), ATM machine/bank (bank card) and then Turn on the power. If the existing RFID reader supports it, it can also switch standby/active (start sending radio frequency) according to the reader signal. If the user needs to charge frequently, there is no convenience. In addition, the indicator light can also be used to prompt the user that the battery is too low.
以上描述仅是本发明的实施例，并不意在限制本发明的范围。根据本公开的权利要求书和说明书的各种变化和修改仍在所要求保护的发明的范围内。此外，每个实施例和权利要求书未必包含了所公开的所有优点或特性。此外，摘要和标题仅用于便于搜索专利文献,并且不旨在以任何方式限制所要求保护的发明的范围。The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Various changes and modifications according to the claims and specification of the present disclosure are still within the scope of the claimed invention. In addition, each embodiment and claims may not include all the advantages or characteristics disclosed.
