—种基于蓝牙判别运动趋势的方法 - kind of Bluetooth-based methods for Distinguishing trend

技术领域 FIELD

[0001] 本发明涉及一种判别运动趋势的方法,特别是一种基于蓝牙判别运动趋势的方法。 [0001] The present invention relates to a method for determining the movement trend, in particular a movement trend is determined based on the Bluetooth method.

背景技术 Background technique

[0002] 当前定位技术主要分为两类:室外定位技术和.室内定位技术。 [0002] The current positioning technology is mainly divided into two categories: outdoor and indoor positioning technology positioning technology.

[0003]目前,室外定位系统有美国的GPS、俄罗斯的格洛纳斯系统、中国的北斗系统以及欧洲的伽利略及移动运营网基站(AGPS)定位技术。 [0003] Currently, the outdoor positioning systems are the US GPS, the Russian GLONASS system, China's Compass system and the European Galileo network base stations and mobile operators (AGPS) positioning technology. 在室外采用卫星定位具有覆盖范围广、用户接入量大等优势。 In outdoor use with satellite positioning wide coverage, user access and other big advantage. 但是因为室外定位技术中均存在一些固有缺点:定位精度低、室内信号弱、搜星时间长等。 But because the outdoor positioning technologies are some inherent disadvantages: low positioning accuracy, indoor signal is weak, a long time Star Search. 然而当用户进入到室内的时候,这些定位系统的定位精度就急剧下降。 However, when the user enters the room when the positioning accuracy of the positioning system on a sharp decline. 主要是因为室内阻隔对信号的影响。 Mainly because of the impact on the signal indoors barrier. 所以,为了解决室内定位的问题,衍生了多种室内定位系统和方法。 Therefore, in order to solve the problem of indoor positioning, derived from a variety of indoor positioning systems and methods.

[0004] 当前应用于室内定位的主要技术有UWB(超宽带)、RFID (射频识别)和蓝牙(Bluetooth)等技术。 [0004] The current applied to the primary indoor positioning technologies have UWB (Ultra Wideband), RFID (radio frequency identification), and Bluetooth (Bluetooth) technology.

[0005] 一、UWB(超宽带)技术是一种全新的、与传统通信技术有极大差异的通信新技术。 [0005] a, UWB (Ultra Wide Band) technology is a new, new technologies have great differences with traditional communications technology communications. 它不需要使用传统通信体制中的载波,而是通过发送和接收具有纳秒或纳秒级以下的极窄脉冲来传输数据,从而具有GHz量级的带宽。 It is not necessary to use traditional communication system of carriers to transmit data but having nanosecond or less nanosecond very narrow pulse by transmitting and receiving, and thus has a bandwidth of the order of GHz. 超宽带系统与传统的窄带系统相比,具有穿透力强、功耗低、抗多径效果好、安全性高、系统复杂度低、能提供精确定位精度等优点。 UWB systems compared with conventional narrowband system, having a penetration, low power consumption, good anti-multi-path effects, high safety, low system complexity, can provide accurate positioning accuracy and other advantages.

[0006] 二、射频识别即RFID (Rad1 Frequency IDentificat1n)技术,又称电子标签、无线射频识别,是一种通信技术,可通过无线电讯号识别特定目标并读写相关数据,而无需识别系统与特定目标之间建立机械或光学接触。 [0006] Second, i.e. radio frequency identification RFID (Rad1 Frequency IDentificat1n) technology, also known as an electronic tag, radio frequency identification, is a communication technique, can be identified by a particular target radio signals and to read and write data, without specific identification system establishing contact between the target mechanical or optical. 目前RFID技术应用很广,如:图书馆,门禁系统,食品安全溯源、室内定位等。 Currently RFID technology is very broad, such as: libraries, access control systems, food safety, traceability, indoor positioning.

[0007] RFID定位系统组成结构主要包括:电子标签、天线、读写器、中央信息系统(计算机)。 [0007] RFID location system composition structure includes: an electronic tag, the antenna, the reader, central information system (computer). 如图1所示。 As shown in Figure 1.

[0008] RFID定位系统的基本工作原理:标签进入磁场后,接收解读器发出的射频信号,凭借感应电流所获得的能量发送出存储在芯片中的产品信息(Passive Tag,无源标签或被动标签),或者由标签主动发送某一频率的信号(Active Tag,有源标签或主动标签),解读器读取信息并解码后,送至中央信息系统进行有关数据处理。 [0008] The basic principle of RFID location system: the label into the magnetic field, receives radio frequency signals emitted by interpretation, transmits the product information stored in the chip (Passive Tag, a passive tag or a passive tag with an energy induced current obtained after), or the signal (active tag, active tags or active tags) sends a certain frequency by the tag, the reader reads the information and decoded information to a central data processing system related.

[0009] RFID定位系统的缺点列举如下: Disadvantage [0009] RFID location system are listed below:

[0012] 3.RFID系统中的电子标签存在不可控性,涉及隐私问题。 [0012] in the presence of the electronic tag system 3.RFID uncontrollable, privacy concerns. (RFID电子标签无法确认该RFID读写器是否合法,当其一旦进入到读写器传感范围,就会无条件的自动发出标签身份讯息,容易导致个人隐私的泄露。) (RFID electronic tags can not confirm the legality of the RFID reader, when once it enters the sensing range of the reader, it will automatically send unconditional identity label message, easily lead to disclosure of personal privacy.)

[0013] 4.国际上没有统一的RFID频率开放频段,各国开放频段都有所不同,一致性上存在差异问题。 [0013] 4. There is no internationally unified open RFID frequency band, the band open countries are different, there are differences on the issue consistency. RFID技术所使用的频段为50KHZ-5.8GHz,且各系列标准的应用范围也有较大差异。 Band RFID technology used is 50KHZ-5.8GHz, each series of standards and the scope of application is also quite different.

[0014] 三、蓝牙(Bluetooth)技术实质是一种短距离无线通信标准。 [0014] Third, the Bluetooth (Bluetooth) technique is essentially a short-distance wireless communication standard. 它以低成本的近距离无线连接为基础,为固定与移动设备通信环境建立一个特别连接来进行设备间的数据通信。 It is low-cost short-range wireless connection is established based on a particular connection for data communication between the stationary equipment and the mobile device communication environment. 蓝牙标准工作频段为2.4GHz的ISM频段。 Bluetooth standard working frequency band of 2.4GHz ISM band. 最新蓝牙4.0版本依旧向下兼容,包含经典蓝牙技术规范和最高速度24Mbps的蓝牙高速技术规范,一般通讯距离在15米以内,最大通讯距离可超过100米。 The latest version is still backward compatible with Bluetooth 4.0, containing classic Bluetooth specification and maximum speed of 24Mbps high-speed Bluetooth specification, general communication within a distance of 15 meters, the maximum communication distance over 100 meters.

[0016] 首先,需要构建复杂的蓝牙AP传输通信网络。 [0016] First, the need to build a complex communication network Bluetooth AP transmissions.

[0017] 然后,蓝牙AP接收到移动终端广播信息后,将信息传输至专用服务器处理。 [0017] Then, after the Bluetooth AP to the mobile terminal receiving the broadcast information, transmit information to a dedicated server process.

[0018] 服务器将处理后的结果,再次通过蓝牙AP传输给移动终端,最终转换成移动终端室内位置。 The results [0018] The processing server, the mobile terminal again to the AP via Bluetooth, the mobile terminal is finally converted into an indoor location.
