图1为本申请实施例提供的一种室内定位系统的结构示意图。FIG. 1 is a schematic structural diagram of an indoor positioning system provided by an embodiment of the application.
如图1所示,室内定位系统100包括:设置在室内的多个LiFi通信端110、移动终端120和服务器130。As shown in FIG. 1, the indoor positioning system 100 includes a plurality of LiFi communication terminals 110, a mobile terminal 120, and a server 130 arranged indoors.
LiFi,即光保真(Light Fidelity,简称LiFi)技术,可以通过光照上网,将光照当作网络信号的传输工作,实现数据传输。LiFi具有低辐射、低能耗和低碳环保的特点。LiFi, or Light Fidelity (LiFi) technology, can use light to surf the Internet and use light as the transmission of network signals to realize data transmission. LiFi has the characteristics of low radiation, low energy consumption, low carbon and environmental protection.
室内通常安装有多个照明装置,这些照明装置可以安装在室内的顶部,安装方式可以采用线吊式、吸顶式、嵌入式等多种方式进行安装,本申请对照明装置的安装方式不作限制。There are usually multiple lighting devices installed in the room. These lighting devices can be installed on the top of the room. The installation methods can be installed in a variety of ways such as wire hanging, ceiling, and embedded. This application does not limit the installation methods of the lighting devices. .
LiFi通信技术是利用肉眼不可见的高速明暗闪烁信号来传输信息的,将高速因特网的电线装置连接在照明装置上,即可实现光照上网。从而,本实施例中,可以借助室内已有的多个照明装置,将多个照明装置作为多个LiFi通信端,以实现LiFi通信。LiFi communication technology uses high-speed light and dark flashing signals that are invisible to the naked eye to transmit information. Connect the high-speed Internet wire device to the lighting device to realize the light and Internet. Therefore, in this embodiment, multiple existing lighting devices in the room can be used to use multiple lighting devices as multiple LiFi communication terminals to implement LiFi communication.
本实施例中,多个LiFi通信端110用于与移动终端120进行LiFi通信,移动终端120向目标LiFi通信端110发送定位请求,其中,定位请求中包含移动终端120的标识,目标LiFi通信端110是多个LiFi通信端110的一个,具体可以是离移动终端最近的LiFi通信端。In this embodiment, multiple LiFi communication terminals 110 are used for LiFi communication with the mobile terminal 120, and the mobile terminal 120 sends a positioning request to the target LiFi communication terminal 110, where the positioning request includes the identification of the mobile terminal 120, and the target LiFi communication terminal 110 is one of multiple LiFi communication terminals 110, and specifically may be the LiFi communication terminal closest to the mobile terminal.
也就是说,移动终端120可与商场内的一个LiFi通信端110进行LiFi通信,将定位请求发送给目标LiFi通信端110。比如,用户在手机上打开了定位软件,这时手机通过LiFi通信将定位请求发送给手机正对的照明装置。In other words, the mobile terminal 120 may perform LiFi communication with a LiFi communication terminal 110 in the shopping mall, and send a positioning request to the target LiFi communication terminal 110. For example, the user opens the positioning software on the mobile phone, and the mobile phone sends a positioning request to the lighting device facing the mobile phone through LiFi communication.
服务器130接收目标LiFi通信端110发送的定位请求,其中,服务器130可以通过电力线载波通信方式、有线网络通信方式或者无线保真(Wireless-Fidelity,简称WiFi)通信方式中的任意一种方式与多个LiFi通信端110进行通信。The server 130 receives the location request sent by the target LiFi communication terminal 110, where the server 130 can use any one of the power line carrier communication method, the wired network communication method, or the wireless fidelity (Wireless-Fidelity, WiFi for short) communication method. Two LiFi communication terminals 110 communicate.
本实施例中,目标LiFi通信端110将定位请求发送给服务器130时,可同时将目标LiFi通信端110的标识发送给服务器130,或者服务器130在接收到定位请求时,确定目标LiFi通信端110的IP地址,IP地址可以看作是目标LiFi通信端110的标识。In this embodiment, when the target LiFi communication terminal 110 sends a positioning request to the server 130, the identification of the target LiFi communication terminal 110 may be sent to the server 130 at the same time, or the server 130 may determine the target LiFi communication terminal 110 when receiving the positioning request. The IP address can be regarded as the identification of the target LiFi communication terminal 110.
服务器130在获取定位请求后,根据目标LiFi通信端110的标识,确定移动终端120的位置,比如,根据目标LiFi通信端110的标识,确定目标LiFi通信端110在室内的位置,进而根据目标LiFi通信端110在室内的位置,确定移动终端130的位置。After the server 130 obtains the positioning request, it determines the location of the mobile terminal 120 according to the identification of the target LiFi communication terminal 110, for example, according to the identification of the target LiFi communication terminal 110, determines the indoor position of the target LiFi communication terminal 110, and then according to the target LiFi communication terminal 110. The indoor location of the communication terminal 110 determines the location of the mobile terminal 130.
以商场为例,移动终端的位置120包括所在楼层和所在店面,具体地,确定移动终端所在楼层,以及在该楼层的哪个店面,或者哪个店面附近。比如,移动终端位于商场2楼的首饰店内。又如,移动终端位于商场3楼滑冰场外的走廊。Taking a shopping mall as an example, the location 120 of the mobile terminal includes the floor and the store where the mobile terminal is located. Specifically, it determines the floor where the mobile terminal is located, and which store on the floor or near which store is located. For example, the mobile terminal is located in a jewelry store on the second floor of a shopping mall. For another example, the mobile terminal is located in the corridor outside the skating rink on the 3rd floor of the shopping mall.
以医院为例,确定的移动终端的位置包括在楼层和科室或病房。以写字楼为例,确定的移动终端的位置包括所在楼层和所在公司或机构。Taking a hospital as an example, the determined location of the mobile terminal includes floors and departments or wards. Taking an office building as an example, the determined location of the mobile terminal includes the floor and the company or institution where it is located.
服务器130确定移动终端120的位置后,将移动终端120的位置通过目标LiFi通信端110发送给移动终端120,移动终端120获取位置信息后,可将位置信息发送给联系人,或者可展示位置信息等。具体地,可以是通过文字、语音等方式展示位置信息。After the server 130 determines the location of the mobile terminal 120, it sends the location of the mobile terminal 120 to the mobile terminal 120 through the target LiFi communication terminal 110. After the mobile terminal 120 obtains the location information, it can send the location information to the contact or display the location information. Wait. Specifically, the location information may be displayed by means of text, voice, or the like.
本实施例中,移动终端120可以是智能手机、平板电脑、穿戴式设备等可移动电子设备。In this embodiment, the mobile terminal 120 may be a mobile electronic device such as a smart phone, a tablet computer, or a wearable device.
需要说明的是,LiFi协议的底层与WiFi802.11基带兼容,在传输数据时,利用WiFi中的TDD协议可以实现一对多或者多对一的同时传输,并且采用LiFi技术传输数据时有极高的安全性,因为光线只能沿直线传播,因此只有处在光线传播直线上的移动终端才有可能截获信息。并且由于LiFi的低延时性,能够应用需要快速传输数据的场景中。It should be noted that the bottom layer of the LiFi protocol is compatible with WiFi 802.11 baseband. When transmitting data, the TDD protocol in WiFi can be used to achieve one-to-many or many-to-one simultaneous transmission, and it is extremely high when using LiFi technology to transmit data. Because the light can only travel along a straight line, only the mobile terminal on the straight line of light can intercept information. And because of the low latency of LiFi, it can be used in scenarios that require fast data transmission.
本申请实施例中,通过在室内设置多个LiFi通信端,用于与移动终端进行LiFi通信,移动终端向多个LiFi通信端中的目标LiFi通信端发送定位请求,服务器接收目标LiFi通信端发送的定位请求,并根据目标LiFi通信端的标识,确定移动终端的位置,并将移动终端的位置通过目标LiFi通信端发送给移动终端,实现了对移动终端进行具体位置的定位,比如在商场内所在楼层和所在店面等,定位效率高。并且,移动终端与LiFi通信端通过LiFi进行通信,方向性好,传输距离短,相较于电磁波通信方式,不仅信息传输速度快,而且信息不易泄露,提高了安全性;由于采用光通信方式传输数据,对频带无限制,从而不会受到干扰,保证了数据传输的可靠性。In the embodiment of this application, by setting up multiple LiFi communication terminals indoors for LiFi communication with the mobile terminal, the mobile terminal sends a positioning request to the target LiFi communication terminal among the multiple LiFi communication terminals, and the server receives the target LiFi communication terminal. According to the identification of the target LiFi communication terminal, the position of the mobile terminal is determined, and the position of the mobile terminal is sent to the mobile terminal through the target LiFi communication terminal, which realizes the positioning of the specific position of the mobile terminal, such as in a shopping mall High positioning efficiency for floors and stores. In addition, the mobile terminal and the LiFi communication terminal communicate via LiFi, which has good directivity and short transmission distance. Compared with electromagnetic wave communication, not only the information transmission speed is fast, but the information is not easy to leak, which improves the security; due to the use of optical communication for transmission The data has no restriction on the frequency band, so that it will not be interfered, and the reliability of data transmission is guaranteed.
