RFID的技术原理和应用简介(一)——RFID的基本概念及分类 * TOC {:toc} RFID是近年来发展较快、引起广泛关注的信息传输技术之一。在物联网时代,各行业都在探索利用这项技术来提升自身效率和降低成本。在这个过程中,我们需要对这项技术有一个基础的了解。 下面,我们先来看看RFID相关的几个概念。 首先是标签(Tag),它包含一个芯片和一个天线。芯片存储着数据信息,天线用于接收发射信号。通过与读写器进行通信,标签可以将数据发送到读写器上。在某些情况下,标签也可以接收数据并存储在自己内部。 其次是读写器(Reader),它包含一个天线、一个微处理器以及一个接口。通过天线发出信号,读写器可以感知到附近所有活动标签,并从中获取信息;同时,它还能够向标签发送信息。通过与外部设备连接,读写器可以将获取到的信息传输给外部设备进行处理或者存储。 最后是服务器(Server),它主要负责对接收到的信息进行处理或者存储,并且能够将需要传输给标签或者读写器的信息发送出去。 除此之外,还有一种称为集中式架构(Centralized Architecture)的系统结构。在这种结构中,所有读写器都直接连接到服务器上,并且只有服务器才能够与其他设备进行通信。 ![img](https://www.cnblogs.com/wangxiaowei/p/10075489.html) 如图所示,在集中式架构中,服务器位于核心位置,并且所有通信都经过它进行转发。由于所有通信都必须经过服务器转发,因此当服务器出现故障时整个系统就会失效。 为了解决这个问题,在分布式架构(Distributed Architecture)中引入了局域网(LAN)节点。局域网节点负责将读写器与服务器连接起来,并且能够直接与其他局域网节点进行通信。 ![img](https://www.cnblogs.com/wangxiaowei/p/10075503.html) 如图所示,在分布式架构中,局域网节点承担了部分服务器的功能,并且能够直接与其他节点进行通信。因此当某个局域网节点出现故障时,整个系统仍然可以正常工作。 根据以上介绍可知,在集中式架构中只有单个服务器存在而没有任何局域网节点;而在分布式架构中则存在多个局域网节点以及一个或多个服务器。 根据以上介绍可知,在集中式架构中只有单个服务器存在而没有任何局域网节点;而在分布式架构中则存在多个局域网节点以及一个或多个服务器。 根据以上介绍可知,在集中式架构中只有单个服务器存在而没有任何局域网节点;而在分布式架构中则存在多个局域网节点以及一个或多个服务器。 根据以上介绍可知,在集中式架构中只有单个服务器存在而没有任何局域能区别:是否使用无线电频率识别(RFID) 根据以上介绍可知,在集中式架构和分布式架构都可以使用无线电频率识别(RFID)技术;但是两者之间最大不同点就是是否使用无线电频率识别(RFID)。 具体地说: * 在集中式架构下:每台读写器都连接到单独一台服务器上;因此每台读写器只能识别该机房内相邻区域内移动物品上贴着的标签; * 在分布式架构下:每台读写器都连接到网络内某台机房上;因此每台读写器可以识别网络范围内移动物品上贴着的标签。 因此如果要实现全站范围内无缝追踪物品流向,则必须采用分布式架构方案。 以下是对比两种方案优缺点: * 集中化方案: 优点:系统设计简单、管理成本低、易于扩展; 缺点:容错性差、不能支持大规模部署; * 分布化方案: 优点:容错性好、支持大规模部署; 缺点:系统设计复杂、管理成本高。 总结: 选择哪种方案取决于具体需求场景以及预算等因素。<|repo_name|>zhaoyang21/blogs<|file_sep[Apache Kafka详解](https://blog.csdn.net/weixin_44556865/article/details/104827747) --- title: Apache Kafka详解 date: '2020-05-07T10:12:58+08:00' author: 程序员小白鸡 tags: --- Apache Kafka 是由 LinkedIn 公司开源并贡献给 Apache 基金会开源项目社区后面广受欢迎并成为目前非常流行和成功的消息队列平台软件之一。 Kafka 的设计初衷就是为了处理像日志这样事件驱动数据流量(Event Driven Data Flows)。例如你可能想要收集来自各种来源(例如日志文件)生成数据流并把他们发布到订阅者(例如实时消费者应用程序)。另外你可能希望把消息发布到不同目标(例如Hadoop、Solr等),同时也希望你能够把历史数据重新导入进去供新加入订阅者使用。 Kafka 支持通过 O(1) 的磁盘数据结构提供消息持久化性,在容量无限制情况下保证常数时间复杂度地查找历史记录。Kafka 还允许客户端指定他们想要消费数据的速度,并且允许 broker 集群透明地水平伸缩以应对增长的消息量。 Kafka 的设计灵感来源于 Twitter 的 Storm 和 Samza 流计算框架以及 Google 的 BigTable 和 Flume 流处理框 架等等。Kafka 设计目标如下: * 处理实时数百万条事件每秒。 * 支持海量客户端数千甚至更多。 * 可以水平伸缩到上百 TB 级别。 * 提供完整端到端强一致性保证。 * 提供顺序保证语义(即使重启也不会丢失消息) * 可以运行几周不间断服务而不需要重新加载日志文件。 * 支持在线人工干预修复问题。(即便遇见问题也能尽可能少影响用户) * 完全开源并由社区支持开发。 Kafka 消息模型: ![img](https://images2017.cnblogs.com/blog/1225465/201711/1225465-20171125123846651-1651438607.png) Kafka 消息模型主要由以下组件组成: Producer 发送消息到 Broker 集群里指定 topic 中, Consumer 订阅 topic 中消息并消费, Broker 维护着发布过来得消息, Topic 表示逻辑上一个主题命名空间划分类别, Partition 物理上 Kafka 是按照 partition 来保存消息日志文件, Replica 在 broker 上保存该 partition 多副本提高可靠性, Consumer Group kafka consumer 可以自动平衡各自消费任务, Log 系统 kafka 就是一个 Partitioned Log System (partitioned 日志系统) Kafka 消息特性: 延迟能力强:kafka 能够能力强很大程度上得益于其底层设计思路——“log”。kafka 就像数据库里面表里面记录条目那样去保存 message 数据记录条目。“log” 不仅仅表示“记录”,更重要得意义就是 kafka 把 log 当做顺序 IO 来处理从而达到高效率得结果。“log”的格式跟日志文件很像但不完全相同,“log” 是二进制格式存储 message 数据记录条目,“log” 包含多条 message 记录条目,“log” 是 append 只追加操作永远不删除,“log” 文件按照时间顺序排列先进先出 FIFO 模型,“log”的大小可以配置默认为1GB。“log” 文件被拆分为若干 segment ,segment 默认大小512MB。“log”的文件名字格式为topic名称+数字编号.log ,数字编号从0开始递增。“segment”的文件名字格式为topic名称+数字编号.index 和 topic 名称+数字编号.log 。index 文件包含该 segment 所有 message 记录条目 offset 和 size ,offset 是第几条记录 size 是该记录大小单位字节 ,index 文件按照 offset 排序 “segment”的大小默认512MB 当超过配置大小后会触发新建 segment 并创建新 index 文件 ,老 segment 被划归为老旧 segment 当前正在被操作 segment 称之为当前 active segment .segment 的最小单位称之为record “record”就是 kafka 中真正意义上得 message 单位 “record” 包含 offset key value timestamp magic byte 四元素其中 magic byte 标记 record 版本号 。offset 表示该 record 在 log 中第几条记录 key 表示 record 的唯一键值 value 表示真正意义得 message 数据 timestamp 表示生产时间 magic byte 标记版本号 record
