具体实施方式
目前，RFID技术广泛应用于各个领域如制造业，利用RFID技术为智能化车间、仓储、工业产线中的产品进行信息检测如位置检测是当前应用较多的场景之一。
比如，将单体物料、箱体物料、转运托盘等物品上贴上电子标签，通过RFID技术进行电子标识，通过电子仓储，实现出入库管理的自动化、自动识别并处理物料出入货架、快速拣货和存货、支持整库/分类/分区的快速电子盘存、以及存量预警并支持对货单的管理与补给。
然而，对于一些场景，如大型工业现场，在进行信息检测时需要额外部署RFID系统，如需要额外部署发射器，读写器，编码器及天线等设备，导致部署成本高昂。并且，RFID技术进行信息检测时存在覆盖范围小，功率消耗大，易受干扰，定位精度不稳定的特点。基于此，本公开实施例提供一种新的信息检测方案。
下面将结合本公开实施例中的附图，对本公开实施例中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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获取的所有其他实施例，都属于本公开保护的范围。
下面首先对相关技术进行说明。
RFID技术可以通过无线电波，在不接触电子标签的情况下快速实现信息交换和存储，其可以通过无线通信结合数据访问技术连接数据库系统，加以实现非接触式的双向通信，从而可以达到识别的目的，其可以用于数据交换，来串联起一个极其复杂的系统。
在识别系统中，可以通过电磁波实现电子标签的读写与通信。图1是RFID系统的工作原理示意图，如图1所示，RFID系统可以包括RFID读写器101、电子标签102和数据管理系统103三部分。RFID读写器通过其天线1011向外发送一定频率的电磁波，当电子标签进入到RFID读写器天线的工作范围内后其内部产生感应电流而被激活，于是将其存储的信息通过内部天线发送出来，RFID读写器的天线接收到来自电子标签的载波信号，将其传送给RFID读写器，RFID读写器对接收到的信号进行解调与解码处理。而数据管理系统与RFID读写器可以通过无线访问接入点进行通信，交互终端可以通过访问RFID读写器并获得信息。
基于RFID技术，可以实现智能产品全生命周期管理，智能化物流仓储以及智能生产车间管理。
数字化室分系统可以包括通信基站，该通信基站可以为皮基站，其为分布式基站， 如图2所示，通信基站可以包括基带单元(Base Band Unit，BBU)201、室内型射频拉远单元(Pico Remote Radio Unit，pRRU)202和汇聚单元203。该通信基站可以为第4代4G通信基站，也可以为第5代通信基站，亦或是更新一代的通信基站，这里不进行具体限定。
BBU的主要作用是集中管理整个基站系统，包括操作维护、信令处理，并完成上、下行用户数据基带处理功能，提供基站与传输网络的接口，完成信息的交互。汇聚单元的主要作用是实现多个pRRU和BBU之间汇聚连接，接收BBU发送的下行数据转发给各pRRU，并将多个pRRU的上行数据转发给BBU，并向pRRU供电。pRRU的主要作用是将数字信号调制到发射频段，经滤波放大后，通过天线发射，从天线接收射频信号，经滤波放大后，将射频信号经模数转换为数字信号后发送给BBU进行处理。
BBU和汇聚单元之间通过光纤204连接，最大拉远距离约为2-15KM之间，汇聚单元与pRRU之间通过光电混合缆205连接，最大拉远距离约为200m。

参见图3，图中示出了本公开实施例提供的信息检测方法的流程示意图。该方法应用于基站，所述基站包括RFID功能模块、接口模块和射频拉远模块，RFID功能模块通过所述接口模块与所述射频拉远模块进行通信，所述射频拉远模块用于进行移动通信，如图3所示，该方法可以包括如下步骤：
步骤301，在电子标签处于所述射频拉远模块的信号覆盖范围内的情况下，通过所述射频拉远模块接收所述电子标签发送的信号，所述信号携带有所述电子标签的标签信息。
本公开实施例中，该基站可以为通信基站，可以称之为皮基站，该通信基站可以为分布式基站。该基站可以为数字化室分系统中的基站，用于将移动通信基站的信号均匀分布在室内每个角落，从而保证室内区域实现比较好的信号覆盖。
在一些实施方式中，该基站可以包括RFID功能模块、接口模块和射频拉远模块，RFID功能模块通过接口模块与射频拉远模块进行通信。该基站可以包括pRRU，RFID功能模块、接口模块和射频拉远模块可以部署在pRRU。

也就是说，射频拉远模块403是建立蜂窝网络基础上，其用于进行移动通信，该射频拉远模块403继承了pRRU的原有功能，可以通过射频模块4031和信号处理单元4033 将数字信号调制到发射频段，经滤波放大后，通过天线发射，从天线接收射频信号，通过射频模块4031和信号处理单元4033经滤波放大后，将射频信号经模数转换为数字信号后发送给BBU进行处理。
在一些实施方式中，RFID功能模块结合射频拉远模块可以实现RFID技术，即可以通过电磁波实现电子标签的读写与通信，在实际应用中，基于RFID技术可以实现智能产品全生命周期管理，智能化物流仓储以及智能生产车间管理。
在一些实施方式中，RFID功能模块可以包括RFID控制模块和RFID应用模块，RFID控制模块可以包括RFID读写器，RFID控制模块可以负责信号编码和解码、执行防碰撞算法、对RFID读写器和电子标签之间传送的数据进行加密和解密、可以进行RFID读写器与电子标签之间的身份验证、以及与RFID应用模块进行通信。而RFID读写器可以负责对电子标签进行读写，RFID应用模块可以具备协议处理、事件生成、命令处理、控制监听等功能。
在一些实施方式中，RFID控制模块可以包括RFID激励器，也可以不包括RFID激励器，这里不进行具体限定。
在一些实施方式中，接口模块可以为使用串行通信RS-232通信接口的模块，也可以为使用传输控制协议(Transmission Control Protocol，TCP)通信接口的模块，还可以为使用网际互连协议(Internet Protocol，IP)通信接口的模块，这里不进行具体限定。
在一些实施方式中，RFID功能模块可以通过接口模块与射频拉远模块进行通信，在RFID功能模块与接口模块进行对接时，RFID功能模块如RFID读写器可以建立在诸如串行通信RS-232、TCP或IP等通信接口上，通过数据交换协议和应用程序实现与射频拉远模块进行通信，从而可以实现RFID功能模块与5G pRRU互通，即可以实现RFID功能模块与pRRU进行融合。
在一些实施方式中，电子标签可以包括耦合元件及芯片，每个标签具有唯一的电子编码，高容量电子标签可以包括可写入的存储空间，附着在物体上可以用于标识该物体。
在一些实施方式中，该电子标签可以为无源电子标签，即需要受到RFID激励源激励后才能发送信号，也可以为有源电子标签，即可以主动发送某一频率的信号，这里不进行具体限定。
在一些实施方式中，RFID功能模块可以包括RFID激励源，在电子标签为无源电子标签的情况下，RFID激励源可以控制RFID读写器通过射频拉远模块进行磁场辐射，当电子标签进入至RFID读写器的磁场辐射范围内时，即说明电子标签处于所述射频拉远模块的信号覆盖范围内，此时，电子标签可以凭借感应电流所获得的能量进行信号发送，以发送出存储在芯片中的标签信息，该标签信息可以包括所标识物体的标识信息和相关产品信息等。
在电子标签为有源电子标签的情况下，RFID功能模块也可以不包括RFID激励源，电子标签可以主动发送某一频率的信号，当电子标签进入至射频拉远模块的信号覆盖范围内时，可以通过射频拉远模块接收电子标签发送的信号，所述信号携带有所述电子标 签的标签信息。
在实际应用中，如智能化工业生产线上，可以将本公开实施例的基站中的多个pRRU部署于周边，以在室内区域实现比较好的信号覆盖，包括室内区域中的该智能化工业生产线，同时可以将电子标签贴于智能化工业生产线中生产的产品上，这样，可以通过该基站实现对电子标签的识别和定位，以进行产品的智能化生产管理。
步骤302，将所述信号通过所述接口模块发送给所述RFID功能模块。
该步骤中，射频拉远模块可以通过接口模块实现与RFID功能模块的互通，射频拉远模块可以通过天线和射频模块接收信号，并在通过信号处理单元进行信号处理后，将接收到的信号通过该接口模块发送给RFID功能模块。
示例性地，RFID功能模块可以包括RFID应用模块，RFID应用模块可以与接口模块进行对接，当RFID应用模块与接口模块进行对接时，可以将RFID读写器建立在诸如串行通信RS-232、TCP或IP等通信接口上，通过数据交换协议和RFID应用模块中的应用程序实现与射频拉远模块进行通信。相应的，射频拉远模块可以将接收到的信号通过该接口模块和RFID应用模块发送给RFID读写器。
该步骤中，RFID功能模块可以复用射频拉远模块中的射频模块和天线来接收电子标签发送的信号，由于5G基站的覆盖范围远，当RFID功能模块与5G基站融合时，可以使得信号覆盖范围宽，连续覆盖效果更好；并且，复用pRRU中的射频模块，由于5G支持多输入多输出(Multiple-Input Multiple-Output，MIMO)的多天线技术，容量更高，能够满足应用场景密集的热点区域覆盖，RFID功能模块复用pRRU中的射频模块后产生高频发射能量，对发射信号进行调制，并传输给电子标签，可以达到对电子标签更好地识别和定位效果。
在实际应用中，pRRU可以采用MIMO多天线技术，如4根发射天线和4根接收天线的天线灵活配置，在负荷不高的情况下，可以将其中的1根发射天线和1根接收天线划分给基于RFID功能模块所构建的子系统，以实现RFID功能，并可以节省资源。
步骤303，通过所述RFID功能模块解析所述信号，得到目标信息，并将所述目标信息发送给RFID服务器，所述目标信息包括所述标签信息。
该步骤中，可以通过RFID功能模块解析所述信号，得到目标信息，该目标信息可以包括电子标签的标签信息，以实现对电子标签的信息识别。
该目标信息也可以同时包括电子标签的标签信息和用于检测该电子标签位置的第一定位信息，该第一定位信息可以为电子标签与接收电子标签信号的该pRRU之间的距离，该第一定位信息用于对电子标签进行定位，如可以基于电子标签与接收该电子标签信号的多个pRRU之间的距离，采用三点定位方式对电子标签进行定位，从而实现对电子标签所标识的物体进行定位。
该第一定位信息可以通过解析接收到的信号强度来确定，也可以通过其他方式来确定，这里不进行具体限定。总之，可以通过解析接收到的信号，得到第一定位信息，以实现对电子标签的定位，从而可以通过部署该基站实现对电子标签所标识的物体进行定 位。
之后，该RFID功能模块可以将目标信息发送给RFID服务器，具体可以通过RFID应用模块将目标信息发送给RFID服务器。其中，RFID服务器可以集成在基站内，也可以不集成在基站内，这里不进行具体限定。
RFID服务器可以根据逻辑运算判断电子标签的合法性，根据不同的设定进行相应的处理和控制，并进行数据处理。同时，RFID服务器也可以根据接收到的多个pRRU发送的第一定位信息实现对电子标签的定位，达到定位效果。
本公开实施例中，通过将RFID功能模块与通信基站进行融合，具体可以将RFID功能模块通过接口模块与通信基站中的射频拉远模块进行通信，来实现融合，这样在电子标签处于射频拉远模块的信号覆盖范围内的情况下，通过射频拉远模块接收电子标签发送的信号，所述信号携带有电子标签的标签信息；将所述信号通过接口模块发送给RFID功能模块；通过RFID功能模块解析所述信号，得到目标信息，并将目标信息发送给RFID服务器。如此，通过将通信基站与RFID功能模块进行融合，并使RFID功能模块复用通信基站的射频拉远模块，从而使通信基站具有了RFID系统的相关功能，从而可以减少对RFID系统的部署，降低部署成本。
并且，pRRU可以接入运营商的网络管理系统，支持每一级的状态监控，有问题更容易排查，易于维护，这就相当于基于RFID功能模块所构建的子系统也可以被监控，同时5G支持MIMO多天线技术，容量更高，能够满足应用场景密集的热点区域覆盖，使得覆盖范围更广，可以达到对电子标签更好地识别和定位效果。

本公开实施方式中，可以通过射频拉远模块并借助于光电混合缆由汇聚单元集线器传输给基带处理模块，以传输给BBU。BBU可以通过网络切片划分的独立频段上传第二定位信息到5G核心网，最后送至云平台进行有关数据处理，以实现对电子标签的定位功能，从而复用数字化室分系统达到电子标签所标识物体的定位效果。
在一些实施方式中，所述RFID服务器集成在所述基带处理模块中，即基带处理模块可以集成BBU和RFID服务器，这样，可以进一步降低RFID系统的部署成本。
参见图5，图5是对电子标签进行定位的系统结构示意图，如图5所示，该系统可以包括数字化室分系统中的通信基站501、电子标签502和云平台503，该通信基站501可以包括pRRU5011、汇聚单元5012和基带处理模块5013，pRRU5011中集成有RFID功能模块，RFID功能模块可以包括RFID读写器50111和RFID激励源50112，基带处理模块5013集成有RFID服务器50131和BBU50132。基于该系统，可以实现对电子标签进行定位。
从以上实施例可以看出，本公开实施例具有用户操作便捷和安全性高的技术优势，例如，1)在5G基站覆盖范围远，当RFID系统与5G基站结合，连续覆盖范围宽，覆盖效果更好；2)在应用场景需要实现定位功能时，可以复用5G基站，无需另外部署RFID系统；3)RFID系统中的射频模块复用皮基站的射频模块，能够支持MIMO多天线技术，容量更高，能够满足应用场景密集的热点区域覆盖；4)皮基站可以接入运营的网络管理系统，支持每一级的状态监控，使得更容易排查问题。也就是说，RFID系统也可以被监控，同时覆盖范围更广。5)pRRU中的4T4R发射模式(4个发射(TX)天线发射4个接收(RX)天线)的天线灵活配置，负荷不高的情况下，其中，1T1R划 分给RFID的子系统，节省资源。
