For example, network equipment and/or terminals can be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; on water; and on aircraft, balloons, and satellites in the air.
需要指出的是，网络设备和终端的角色可以是相对的。例如，图1中的120a为无人机，且被配置成移动基站，通信***中的另一终端(图1中未示出，为了方便描述，称为120b)可以通过120a接入接入网设备110a，对于120b来说，120a是基站；但对于接入网设备110a来说，120a是终端，即接入网设备110a与120a之间是通过无线空口协议进行通信的。当然，接入网设备110a与120a之间也可以是通过基站与基站之间的接口协议进行通信的，此时，相对于接入网设备110a来说，120a也是基站。因此，接入网设备和终端都可以统一称为通信装置，图1中的110a、110b和110c可以称为具有基站功能的通信装置，图1中的120a以及这里提及的120b可以称为具有终端功能的通信装置。It should be pointed out that the roles of network devices and terminals may be relative.

Another terminal in the communication system (not shown in FIG. 1, for convenience of description, referred to as 120b) can access the access network through 120a For the device 110a, for 120b, 120a is a base station; but for the access network device 110a, 120a is a terminal, that is, the access network devices 110a and 120a communicate through a wireless air interface protocol. Of course, communication between the access network devices 110a and 120a may also be performed through an interface protocol between the base station and the base station. In this case, relative to the access network device 110a, 120a is also a base station. Therefore, both the access network equipment and the terminal may be collectively referred to as communication devices, 110a, 110b and 110c in FIG. 1 may be referred to as communication devices with base station functions, and 120a in FIG. 1 and 120b mentioned here may be referred to as communication devices with Terminal-capable communication device.

The functions of the terminal can also be performed by a module (such as a chip or a modem) in the terminal, and can also be performed by a device including the terminal functions.
本申请的实施例对于标签和读写器在通信***中的部署方式不作具体限定。例如，读写器和标签可以作为终端部署在通信***中，读写器和标签之间的通信可以看作旁链路(sidelink)通信。又例如，读写器可以作为接入网设备部署在通信***中(例如，读写器集成在接入网设备中或接入网设备具备读写器的功能等)，标签可以作为终端部署在通信***中。The embodiments of the present application do not specifically limit the deployment manner of the tag and the reader/writer in the communication system. For example, the reader and the tag can be deployed in the communication system as a terminal, and the communication between the reader and the tag can be regarded as sidelink communication. For another example, the reader can be deployed in the communication system as an access network device (for example, the reader is integrated in the access network device or the access network device has the function of the reader, etc.), and the tag can be deployed as a terminal in the communication system. in the communication system.
图2是标签和读写器在通信***中的几种部署方式的示意图。Figure 2 is a schematic diagram of several deployment modes of tags and readers in a communication system.
对于基础覆盖场景，读写器可以作为接入网设备部署在通信***或者与接入网设备部署在一起，接入网设备可以读取标签中的信息和/或向标签写入信息。例如，图2中的宏站210a可以读取标签220a中的信息和/或向标签220a写入信息。又例如，图2中的杆站210c可以读取标签220c中的信息和/或向标签220c写入信息。或者，读写器可以作为终端部署在通信***或者与终端部署在一起。例如，图2中的读写器作为终端与杆站210c部署在一起，210c可以读取标签220c中的信息和/或向标签220c写入信息。For basic coverage scenarios, the reader can be deployed in the communication system as an access network device or together with the access network device, and the access network device can read the information in the tag and/or write information to the tag. For example, macro station 210a in FIG. 2 may read information from and/or write information to tag 220a. As another example, the pole station 210c in FIG. 2 may read information from and/or write information to the tag 220c. Alternatively, the reader/writer can be deployed as a terminal in the communication system or together with the terminal. For example, the reader in FIG. 2 is deployed as a terminal with pole station 210c that can read information from and/or write information to tag 220c.
对于补充覆盖场景，读写器可以作为终端部署在通信***中，读写器与接入网设备之间通过uu(UE-UTRAN)接口进行数据传输，即空口传输，读写器与标签之间可以看作旁链路通信。例如，图2中的宏站210b与读写器230b可以通过uu接口通信，读写器230b可以读取标签220b中的信息和/或向标签220b写入信息。又例如，图2杆站210d与读写器230d可以通过uu接口通信，读写器230d可以读取标签220d中的信息和/或向标签220d写入信息。又例如，图2杆站210e与读写器230e可以通过uu接口通信，读写器230e可以读取标签220e中的信息和/或向标签220e写入信息，若标签220e具备空口通信能力，标签220e也可以直接与杆站210e进行通信。For supplementary coverage scenarios, the reader can be deployed as a terminal in the communication system, and data transmission is performed between the reader and the access network equipment through the uu (UE-UTRAN) interface, that is, air interface transmission, between the reader and the tag It can be seen as side link communication. For example, the macro station 210b in FIG. 2 and the reader/writer 230b may communicate through a uu interface, and the reader/writer 230b may read information in the tag 220b and/or write information to the tag 220b. For another example, in FIG. 2, the pole station 210d and the reader/writer 230d may communicate through a uu interface, and the reader/writer 230d may read information in the tag 220d and/or write information to the tag 220d. For another example, in FIG. 2, the pole station 210e and the reader 230e can communicate through the uu interface, and the reader 230e can read the information in the tag 220e and/or write information to the tag 220e. If the tag 220e has the air interface communication capability, the tag 220e can 220e may also communicate directly with pole station 210e.
现有的RFID***可以通过无线射频方式，实现读写器对标签的读写。但是现有的RFID***尚未规定如何存储和读写传感数据。针对上述问题，本申请提供了用于读取数据的方法和装置，能够实现存储和读取传感数据。The existing RFID system can realize the reading and writing of the tag by the reader and writer by means of radio frequency. But existing RFID systems have not yet specified how to store and read and write sensor data. In view of the above problems, the present application provides a method and apparatus for reading data, which can realize the storage and reading of sensor data.
下面首先对本申请的实施例的传感数据的存储空间进行描述。The storage space of the sensing data in the embodiments of the present application is first described below.
在本申请中，标签支持存储至少一个传感器的传感数据。若标签支持存储多个传感器的传感数据，该多个传感器的类型可以相同，也可以不同，不予限制。In the present application, the tag supports the storage of sensory data of at least one sensor. If the tag supports storing the sensing data of multiple sensors, the types of the multiple sensors may be the same or different, which is not limited.
在一些实现方式中，每个传感数据可以占用单独的存储空间。例如，第一传感数据可 以占用第一存储区、第一字节区间、第一存储区的第一文档(file)、第一存储区的第一文档的第一字节区间、或第一存储区的第一字节区间等。需要说明的是，文档(file)也可以替换为文件等，本申请同一描述为文档。In some implementations, each sensory data may occupy a separate storage space. For example, the first sensory data may occupy the first storage area, the first byte interval, the first file of the first storage area, the first byte interval of the first file of the first storage area, or the first The first byte range of the storage area, etc. It should be noted that the document (file) may also be replaced by a file, etc., and the same description is referred to as a document in this application.
换句话说，传感数据可以与存储区一一对应，例如，第一传感数据对应于第一存储区。传感数据可以与字节区间一一对应，例如，第一传感数据对应于第一字节区间。传感数据可以与文档一一对应，例如，第一传感数据对应于第一存储区的第一文档。传感数据也可以与字节区间一一对应，例如，第一传感数据对应于第一存储区的第一文档的第一字节区间，或者对应于第一存储区的第一字节区间。若标签中包括多个存储区，读写器可以先为多个传感数据分配存储区，再进一步为多个传感数据分配不同的文档或字节区间。In other words, the sensing data may correspond to the storage areas one-to-one, for example, the first sensing data corresponds to the first storage area. The sensing data may be in one-to-one correspondence with byte intervals, for example, the first sensing data corresponds to the first byte interval. The sensory data may be in one-to-one correspondence with documents, for example, the first sensory data corresponds to the first document in the first storage area. The sensor data may also correspond to the byte interval one-to-one. For example, the first sensor data corresponds to the first byte interval of the first document in the first storage area, or corresponds to the first byte interval of the first storage area. . If the tag includes multiple storage areas, the reader can first allocate storage areas for multiple sensor data, and then further allocate different documents or byte ranges for multiple sensor data.
在本申请中，传感数据占用的存储空间可以是新增加的专门用于存储传感数据的空间，也可以是已有存储区中的存储空间，对此不作具体限定。In this application, the storage space occupied by the sensing data may be a newly added space dedicated to storing the sensing data, or may be a storage space in an existing storage area, which is not specifically limited.
下面结合具体的示例，对传感数据占用的存储空间进行描述。The storage space occupied by the sensor data will be described below with reference to specific examples.
图3是传感数据占用的存储空间的一个示例。FIG. 3 is an example of storage space occupied by sensor data.
在图3所示的示例中，通过新增加第一存储区来存储传感数据。如图3所示，标签的内存包括：保留区、EPC区、TID区、用户区、以及第一存储区。In the example shown in FIG. 3 , the sensing data is stored by newly adding the first storage area. As shown in FIG. 3 , the memory of the tag includes: a reserved area, an EPC area, a TID area, a user area, and a first storage area.
1)保留区1) Reserved area
保留区也称为保留存储区，用于存储kill(灭活)和access(访问)功能所需的密码。其中，存储地址00h到1Fh存储kill密码，20h到3Fh存储access密码。没有执行过kill和/或access密码的标签，可以看作具有零值的密码，并被永久的读/写锁定，在保留区里的密码存储区中不用保存零值的密码。The reserved area, also known as the reserved storage area, is used to store the passwords required for the kill (deactivation) and access (access) functions. Among them, the storage addresses 00h to 1Fh store the kill password, and 20h to 3Fh store the access password. A tag that has not executed the kill and/or access password can be regarded as a password with a zero value and is permanently read/write locked. The password storage area in the reserved area does not store a password with a zero value.
2)EPC区2) EPC area
EPC区也称为EPC存储区，用于存储EPC号码等。其中，存储地址00h到0Fh存储循环冗余码校验-16(cyclic redundancy check-16，CRC-16)，10h到1Fh存储协议控制位(protocol control，PC)，20h及其大于20h的存储地址存储用于识别标签附着对象的代码。The EPC area is also called the EPC storage area and is used to store EPC numbers and the like. Among them, storage addresses 00h to 0Fh store cyclic redundancy check-16 (cyclic redundancy check-16, CRC-16), 10h to 1Fh store protocol control bits (protocol control, PC), 20h and its storage addresses greater than 20h Stores the code used to identify what the label is attached to.
3)TID区3) TID area
TID区也称为TID存储区，用于存储标签识别码。其中，存储地址00h到07h存储一个8位的类识别码，07h以上的存储地址应包含充足的识别信息，使读写器能唯一识别标签所支持的定制命令和/或可选择性命令。The TID area, also known as the TID storage area, is used to store the tag identification code. Among them, storage addresses 00h to 07h store an 8-bit class identification code, and storage addresses above 07h should contain sufficient identification information so that the reader can uniquely identify the custom commands and/or optional commands supported by the tag.
4)用户区4) User area
用户区也称为用户存储区，用于存储用户定义的数据。用户区的存储组织结构可以由用户定义。The user area, also known as the user memory area, is used to store user-defined data. The storage organization structure of the user area can be defined by the user.
需要说明的是，保留区、EPC区、TID区、和用户区的更详细的描述可以参考现有技术，在此不再赘述。It should be noted that, for a more detailed description of the reserved area, the EPC area, the TID area, and the user area, reference may be made to the prior art, which will not be repeated here.
5)第一存储区5) The first storage area
第一存储区为新增加的存储区，用于存储传感数据。每个传感数据可以单独占用一个文档(file)，也可以占用固定的字节区间，还可以多个传感数据共占用一个文档的不同字节区间。The first storage area is a newly added storage area for storing sensing data. Each sensor data may occupy a single file (file) alone, or may occupy a fixed byte range, or multiple sensor data may occupy different byte ranges of a document.
例如，如图3的(a)图所示，传感器0的传感数据占用第一存储区的第0文档，以 此类推，传感器n的传感数据占用第一存储器的第n文档。For example, as shown in (a) of Figure 3, the sensing data of sensor 0 occupies the 0th file in the first storage area, and so on, the sensing data of sensor n occupies the nth file in the first storage area.
又例如，如图3的(b)图所示，传感器0的传感数据占用第一存储区的字节区间[15：0]，传感器1的传感数据占用第一存储区的字节区间[31：16]，以此类推。For another example, as shown in (b) of FIG. 3 , the sensing data of sensor 0 occupies the byte interval [15:0] of the first storage area, and the sensing data of sensor 1 occupies the byte interval of the first storage area [31:16], and so on.
本申请的实施例对于第一存储区间在实现时的名称不作具体限定。例如，可以称为传感器、senser、sensor、或data等。The embodiments of the present application do not specifically limit the name of the first storage interval during implementation. For example, it may be called sensor, sensor, sensor, or data, etc.
图4是传感数据占用的存储空间的另一个示例。FIG. 4 is another example of storage space occupied by sensory data.
如图4所示，标签的内存包括：保留区、EPC区、TID区、以及用户区。关于保留区、EPC区、TID区、以及用户区的描述可以图3部分的描述，在此不再赘述。与图3不同的是，在图4所示的示例中，通过占用已有存储区的存储空间来存储传感数据，例如，占用保留区、EPC区、TID区、用户区中的一个或多个。As shown in Figure 4, the memory of the tag includes: a reserved area, an EPC area, a TID area, and a user area. The description about the reserved area, the EPC area, the TID area, and the user area can be described in the part of FIG. 3 , and will not be repeated here. Different from Fig. 3, in the example shown in Fig. 4, the sensor data is stored by occupying the storage space of the existing storage area, for example, occupying one or more of the reserved area, the EPC area, the TID area, and the user area. indivual.
以占用用户区为例，不同传感数据可以占用用户区的不同文档、用户区的一个文档的不同字节区间、或者用户区的多个文档的不同字节区间。Taking the occupation of the user area as an example, different sensor data may occupy different documents in the user area, different byte intervals of a document in the user area, or different byte intervals of multiple documents in the user area.
例如，如图4的(a)图所示，传感器0的传感数据占用用户区的第i文档，传感器1的传感数据占用用户区的第i+1文档，其中i为非负整数。For example, as shown in (a) of Figure 4, the sensing data of sensor 0 occupies the i-th document in the user area, and the sensing data of sensor 1 occupies the i+1-th document in the user area, where i is a non-negative integer.
例如，如图4的(b)图所示，多个传感数据占用用户区的第i文档，传感器0的传感数据占用第i文档的字节区间[15：0]，传感器1的传感数据占用第i文档的字节区间[31：16]，以此类推，其中i为非负整数。For example, as shown in (b) of Figure 4, multiple sensor data occupy the i-th file in the user area, the sensor data of sensor 0 occupy the byte interval [15:0] of the i-th file, and the sensor data of sensor 1 The sense data occupies the byte interval [31:16] of the i-th document, and so on, where i is a non-negative integer.
在另一些实现方式中，每个存储区可以是以字节为单位即8比特，则图3和图4中第一个字节区间可以为00—07。In other implementation manners, each storage area may be in units of bytes, that is, 8 bits, and the first byte interval in FIG. 3 and FIG. 4 may be 00-07.
在另一些实现方式中，传感数据还可以被存储在未被定义的存储空间，在这类存储空间存储的数据通常只在上电的时候可以保存，一旦断电，数据就会丢失。例如，传感数据可以被存储在寄存器、缓存器或者其他外部接口之中。在该实现方式中，每个传感数据可以占用单独的存储空间。例如，不同的传感数据可以占用不同的字节区间。In other implementations, the sensor data can also be stored in an undefined storage space. The data stored in this type of storage space can usually only be saved when the power is turned on. Once the power is turned off, the data will be lost. For example, sensory data may be stored in registers, buffers, or other external interfaces. In this implementation, each sensing data may occupy a separate storage space. For example, different sensor data can occupy different byte intervals.
下面对本申请的实施例的传感数据的读写流程进行描述。The following describes the process of reading and writing sensor data in the embodiments of the present application.
图5是本申请的实施例提供的用于读取数据的方法的示意性流程图。图5所示的方法可以由读写器和标签实现，也可以由读写器和标签中的模块或单元实现(例如，芯片、电路、片上***(system on chip，SOC)等)。图5中以执行主体为读写器和标签为例进行描述。图5中的方法可以包括以下内容的至少部分内容。FIG. 5 is a schematic flowchart of a method for reading data provided by an embodiment of the present application. The method shown in FIG. 5 may be implemented by a reader/writer and a tag, or may be implemented by a module or unit (eg, a chip, a circuit, a system on chip (SOC), etc.) in the reader/writer and the tag. In FIG. 5, the execution subject is a reader and a tag as an example for description. The method of FIG. 5 may include at least some of the following.
步骤510，读写器向标签发送第一命令。相应地，标签接收来自读写器的第一命令。其中，第一命令用于读取第一传感数据。Step 510, the reader/writer sends a first command to the tag. Accordingly, the tag receives the first command from the reader. Wherein, the first command is used to read the first sensing data.
也就是说，当读写器想要读取标签的传感数据时，可以通过向标签发送第一命令来获取相应的传感数据。此时标签可以处于开放状态(open)或者安全状态(secured)或者处于连接态，如无线资源控制(radio resource control，RRC)连接态。That is, when the reader/writer wants to read the sensing data of the tag, it can acquire the corresponding sensing data by sending the first command to the tag. At this time, the tag can be in an open state (open), a secure state (secured), or a connected state, such as a radio resource control (radio resource control, RRC) connected state.
可选地，第一命令可以是选择命令(select)、查询命令(query)、读取命令(read)或者其他命令，不予限制。Optionally, the first command may be a selection command (select), a query command (query), a read command (read) or other commands, which are not limited.
在一些实现方式中，第一命令中包括第一信息，第一信息用于指示存储第一传感数据的存储空间。示例性地，若第一传感数据保存在标签的内存中，第一命令可以包括第一信息。In some implementations, the first command includes first information, where the first information is used to indicate a storage space for storing the first sensing data. Exemplarily, if the first sensing data is stored in the memory of the tag, the first command may include the first information.
可选地，第一信息包括存储第一传感数据的存储空间的位置信息。例如，若传感数据 占用存储区，该位置信息可以包括存储区标识。又例如，若每个传感数据占用单独的字节区间，该位置信息可以包括存储区的起始位置、读取字节长度和终止位置中的至少两个；或者，若标签和读写器已经约定好每次读取的长度，该位置信息可以包括起始位置和/终止位置；或者，该位置信息可以包括字节区间的起始位置、读取长度和终止位置中的至少两个、以及存储区标识和文档标识；或者，该位置信息可以包括字节区间的起始位置、读取长度和终止位置中的至少两个、以及存储区标识。又例如，若每个传感数据占用单独的文档，该位置信息可以为存储区标识和文档标识。Optionally, the first information includes location information of a storage space where the first sensing data is stored. For example, if the sensory data occupies a storage area, the location information may include a storage area identification. For another example, if each sensing data occupies a separate byte interval, the location information may include at least two of the starting position of the storage area, the read byte length and the ending position; or, if the tag and the reader/writer The length of each read has been agreed, and the position information may include the start position and/or end position; or, the position information may include at least two of the start position, read length, and end position of the byte interval, and a storage area identification and a document identification; or, the location information may include at least two of a start position, a read length and an end position of a byte interval, and a storage area identification. For another example, if each sensing data occupies a separate document, the location information may be a storage area identification and a document identification.
上述存储区标识可以为存储区的名称，例如，用户区、保留区、EPC区、TID区、或第一存储器区等。The above-mentioned storage area identifier may be a name of a storage area, for example, a user area, a reserved area, an EPC area, a TID area, or a first memory area, and the like.
在另一些实现方式中，第一命令中包括第二信息，第二信息用于指示第一传感数据的类型、第一传感器的标识、传感数据类型的标识和第一传感数据的存储空间的起始位置中的至少一个，第一传感数据为来自第一传感器的数据。传感数据的类型具体可以包括温度传感数据、湿度传感数据等等。In other implementation manners, the first command includes second information, where the second information is used to indicate the type of the first sensing data, the identification of the first sensor, the identification of the type of sensing data, and the storage of the first sensing data At least one of the starting positions of the space, the first sensory data is data from the first sensor. The types of sensing data may specifically include temperature sensing data, humidity sensing data, and the like.
可选地，每次读取的传感数据的数据长度可以约定为固定值，例如，约定读取最近的n次记录、约定每次读取k个字节、或者约定读取m个数据等，n、m和k为大于0的整数，其中，每个记录的字节数和每个数据的数据长度可以约定为固定值，例如8字节或者16字节等。Optionally, the data length of the sensing data read each time can be agreed to be a fixed value, for example, it is agreed to read the latest n records, it is agreed to read k bytes each time, or it is agreed to read m data, etc. , n, m, and k are integers greater than 0, wherein the number of bytes of each record and the data length of each data can be agreed as fixed values, such as 8 bytes or 16 bytes.
可选地，可以在第二信息中携带读取的数据长度或者数据记录数，例如，第二信息可以进一步指示读取最近的n次记录、读取k个字节等，n和k为大于0的整数，其中，每个记录的字节数可以约定为固定值，例如8字节或者16字节等。Optionally, the read data length or the number of data records may be carried in the second information. For example, the second information may further indicate to read the latest n records, read k bytes, etc., where n and k are greater than An integer of 0, where the number of bytes in each record can be agreed to a fixed value, such as 8 bytes or 16 bytes.
在一些实现方式中，第一命令还可以包括待读取的字节长度、待读取的记录的次数和待读取的周期数中的至少一个。也就是说，由读写器告知标签需要读取的传感数据的数据长度。例如，读写器通过第一命令告知标签读取k个字节、最近的n次记录、或m个数据等，n、m和k为大于0的整数，其中，每个记录的字节数和每个数据的数据长度可以约定为固定值，例如8比特或者16比特等。In some implementations, the first command may further include at least one of the length of bytes to be read, the number of records to be read, and the number of cycles to be read. That is to say, the data length of the sensing data that the tag needs to be read is informed by the reader/writer. For example, the reader tells the tag to read k bytes, the latest n records, or m data through the first command, where n, m and k are integers greater than 0, where the number of bytes in each record is And the data length of each data can be agreed to a fixed value, such as 8 bits or 16 bits.
在一些实现方式中，第一命令包括第四信息，第四信息用于指示标签周期性上报传感数据，具体地，第四信息包括上报周期。In some implementation manners, the first command includes fourth information, and the fourth information is used to instruct the tag to periodically report the sensing data. Specifically, the fourth information includes a reporting period.
示例性地，若第一传感数据保存在标签的未被定义的存储空间中，例如存储在寄存器、缓存器或外部接口中。此时第一命令可以不包括第一信息，包含第二消息等等。Exemplarily, if the first sensing data is stored in an undefined storage space of the tag, for example, stored in a register, a buffer or an external interface. At this time, the first command may not include the first information, but may include the second message and so on.
步骤520，标签根据第一命令，向读写器发送第一传感数据。相应地，读写器接收来自标签的第一传感数据。Step 520, the tag sends the first sensing data to the reader according to the first command. Accordingly, the reader/writer receives the first sensing data from the tag.
在一些实现方式中，标签在接收到第一命令后，根据第一命令获取第一传感数据。若获取到读写器要求的第一传感数据，则标签向读写器返回第一传感数据。若无法向读写器返回有效的传感数据，则标签可以向读写器返回一个错误代码，用于指示无法正常返回传感数据，或者标签不响应第一命令，或者标签跳转到其他状态。In some implementations, after receiving the first command, the tag acquires the first sensing data according to the first command. If the first sensing data required by the reader/writer is obtained, the tag returns the first sensing data to the reader/writer. If it cannot return valid sensing data to the reader, the tag can return an error code to the reader to indicate that the sensing data cannot be returned normally, or the tag does not respond to the first command, or the tag jumps to other states .
在一些实现方式中，标签在接收到第一命令后，除了向读写器返回第一传感数据之外，还可以向读写器返回第三信息。第三信息可以包括时间信息，具体可以为时间戳信息，例如反馈传感数据记录的时间，如xx年xx月xx日，xx时xx分；还可以为保存时间信息，例如，收到记录数据到发送时保存的时间等。第三信息可以为已经记录的第一传感数据的 周期数或数据量等。可选地，第三信息还可以包括第一传感数据的标识信息等。In some implementations, after receiving the first command, in addition to returning the first sensing data to the reader, the tag may also return third information to the reader. The third information may include time information, specifically time stamp information, such as the time when the sensory data is fed back, such as xx, xx, xx, xx, xx, xx; it can also be saving time information, such as receiving recorded data to the time saved at the time of sending, etc. The third information may be the number of cycles or the amount of data of the first sensing data that has been recorded. Optionally, the third information may further include identification information and the like of the first sensing data.
可选地，图5所示的方法还可以包括步骤530。Optionally, the method shown in FIG. 5 may further include step 530 .
步骤530，标签向读写器发送第一指示信息。相应地，读写器接收来自标签的第一指示信息。其中，第一指示信息用于指示标签中存储有传感数据。Step 530, the tag sends the first indication information to the reader. Accordingly, the reader/writer receives the first indication information from the tag. The first indication information is used to indicate that sensor data is stored in the tag.
示例性地，在步骤510之前执行步骤530。也就是说，在读写器读取标签传感数据之前，标签可以先向读写器发送第一指示信息，指示已经有记录好或保存好的传感数据，读写器可以进行读取操作。Illustratively, step 530 is performed before step 510 . That is to say, before the reader reads the sensor data of the tag, the tag can first send the first indication information to the reader, indicating that the sensor data has been recorded or saved, and the reader can read it. .
在一些实现方式中，读写器指示标签上报存储的数据量，比如字节数，或者指示标签上报存储的记录的数量，则读写器收到后，可以进一步指示标签上报具体记录的数据，比如时间最近的一次，也可以按照时间顺序指示次数n，标签则上报最近储存的n次数据；标签收到该指示后可以进行相应的反馈，即向读写器发送至第一指示信息，反馈存储的传感数据的情况；读写器接收到第一指示信息后，可以发送第一命令，读取第一传感数据。In some implementations, the reader/writer instructs the tag to report the amount of stored data, such as the number of bytes, or instructs the tag to report the number of stored records, then after receiving it, the reader may further instruct the tag to report the specific record data, For example, for the latest time, the number of times n can also be indicated in chronological order, and the tag reports the latest n times of data; after receiving the instruction, the tag can give corresponding feedback, that is, send the first instruction information to the reader, feedback The situation of the stored sensor data; after receiving the first indication information, the reader can send the first command to read the first sensor data.
在另一些实现方式中，第一指示信息也可以直接携带传感数据。In other implementation manners, the first indication information may also directly carry sensor data.
可选地，图5所示的方法还可以包括步骤540。Optionally, the method shown in FIG. 5 may further include step 540 .
步骤540，标签确定允许读写器读取第一传感数据。Step 540, the tag determines that the reader is allowed to read the first sensing data.
也就是说，在确定允许读写器读取第一传感数据时，标签才会向读写器发送第一传感数据。在确定不允许读写器读取第一传感数据时，标签可以返回错误代码、不响应、或者跳转到其他状态，不予限制。That is to say, when it is determined that the reader/writer is allowed to read the first sensing data, the tag will only send the first sensing data to the reader/writer. When it is determined that the reader is not allowed to read the first sensing data, the tag may return an error code, not respond, or jump to other states, without limitation.
在本申请的实施例中，可以针对传感器、传感数据的类型或存储空间设置权限，只有具备相应读取权限的读写器或者命令才能获取传感数据。In the embodiments of the present application, permissions may be set for sensors, types of sensing data, or storage space, and only readers or commands with corresponding read permissions can acquire sensing data.
在一些实现方式中，每个传感数据的访问具有独立的访问秘钥，只有发送正确的访问秘钥的读写器才可以获取相应传感数据。也就是说，当读写器提供的第一访问秘钥是访问第一传感数据的访问秘钥时，标签确定允许读写器读取第一传感数据。In some implementations, each sensing data access has an independent access key, and only the reader/writer that sends the correct access key can obtain the corresponding sensing data. That is, when the first access key provided by the reader/writer is the access key for accessing the first sensing data, the tag determines to allow the reader/writer to read the first sensing data.
可选地，读写器可以在第一命令中携带第一访问秘钥。Optionally, the reader/writer may carry the first access key in the first command.
可选地，读写器也可以在其他命令或信息中携带第一访问秘钥。Optionally, the reader/writer may also carry the first access key in other commands or information.
在另一些实现方式中，可以对读写器和标签进行鉴权，经过鉴权后的读写器和标签才可以进行传感数据的读取和传输。也就是说，当读写器和标签是鉴权后的读写器和标签时，标签确定允许读写器读取第一传感数据。通过该方式可以简化权限管理。In other implementation manners, the reader and tag can be authenticated, and the reader and tag after authentication can read and transmit sensing data. That is, when the reader-writer and the tag are authenticated readers and tags, the tag determines that the reader-writer is allowed to read the first sensing data. In this way, rights management can be simplified.
在另一些实现方式中，可以为每个传感数据的存储空间设置信令权限，在特定权限内，只允许读写器使用部分命令，其他命令不能接入。例如，可以设置存储某个传感数据的存储空间仅允许读取和/或写入。也就是说，当第一传感数据的存储空间被设置为允许读取时，标签确定允许读写器读取第一传感数据。In other implementations, a signaling authority may be set for the storage space of each sensing data, and within a specific authority, only some commands are allowed to be used by the reader, and other commands cannot be accessed. For example, a storage space that stores certain sensor data can be set to allow only reading and/or writing. That is, when the storage space of the first sensing data is set to allow reading, the tag determines that the reader/writer is allowed to read the first sensing data.
可选地，存储空间的信令权限可以被读写器修改。Optionally, the signaling authority of the storage space can be modified by the reader.
图6是本申请的另一实施例提供的用于读取数据的方法的示意性流程图。如图6所示的方法可以包括以下内容的至少部分内容。FIG. 6 is a schematic flowchart of a method for reading data provided by another embodiment of the present application. The method shown in FIG. 6 may include at least part of the following.
步骤610，读写器向标签发送第二命令。相应地，标签接收来自读写器的第二命令。Step 610, the reader/writer sends a second command to the tag. Accordingly, the tag receives the second command from the reader.
可选地，第二命令可以为上述第一命令或其他命令，不予限制。Optionally, the second command may be the above-mentioned first command or other commands, which is not limited.
在一些实现方式中，第二命令可以包括第六信息和/或第七信息、以及条件信息。其中，第六信息用于指示存储第二传感数据的存储空间，第七信息用于指示第二传感数据的 类型或第二传感器标识，第二传感数据为来自第二传感器的数据，第六信息和第七信息的实现方式可以参考第一信息和第二信息，在此不再赘述。条件信息用于指示上报第二指示信息和/或第二传感数据所需满足的条件，这里的第二指示信息可以用于指示第二传感数据出现异常。In some implementations, the second command may include sixth information and/or seventh information, and condition information. Wherein, the sixth information is used to indicate the storage space for storing the second sensing data, the seventh information is used to indicate the type of the second sensing data or the identification of the second sensor, and the second sensing data is data from the second sensor, For the implementation manner of the sixth information and the seventh information, reference may be made to the first information and the second information, which will not be repeated here. The condition information is used to indicate a condition that needs to be satisfied to report the second indication information and/or the second sensing data, and the second indication information here may be used to indicate that the second sensing data is abnormal.
作为一个示例，条件信息可以包括阈值信息，阈值信息用于确定第二传感数据是否异常。例如，阈值信息包括第一阈值，表示第二传感数据的数值大于第一阈值的标签发送第二指示信息和/或第二传感数据。又例如，阈值信息包括第二阈值，表示第二传感数据的数值小于第二阈值的标签发送第二指示信息和/或第二传感数据。又例如，阈值信息包括第一阈值和第二阈值，表示第二传感数据的数值大于第一阈值且小于第二阈值的标签发送第二指示信息和/或第二传感数据。As an example, the condition information may include threshold information, which is used to determine whether the second sensing data is abnormal. For example, the threshold value information includes a first threshold value, and a tag indicating that the value of the second sensing data is greater than the first threshold value sends the second indication information and/or the second sensing data. For another example, the threshold value information includes a second threshold value, indicating that a tag whose value of the second sensing data is smaller than the second threshold value sends the second indication information and/or the second sensing data. For another example, the threshold value information includes a first threshold value and a second threshold value, indicating that a tag whose value of the second sensing data is greater than the first threshold value and less than the second threshold value sends the second indication information and/or the second sensing data.
作为另一个示例，条件信息可以指示标签需满足的条件，满足条件的标签进行接入，并上报传感数据和/或第二指示信息。例如，条件信息可以指示标签的标识中包含的特定比特且具备传感功能的标签可以上报传感数据和/或第二指示信息。一种具体的实现方式为第二命令中包含该特定比特、以及传感数据上报指示，以便匹配该条件的标签发起接入，等待接入成功后并向读写器发送传感数据和/或第二指示信息，或者匹配该条件的标签直接发送传感数据和/或第二指示信息。As another example, the condition information may indicate a condition that the tag needs to meet, and the tag that satisfies the condition accesses and reports sensing data and/or second indication information. For example, the condition information may indicate specific bits included in the identification of the tag, and the tag with sensing function may report sensing data and/or second indication information. A specific implementation is that the second command includes the specific bit and the sensor data reporting indication, so that the tag matching the condition initiates access, and after the access is successful, the sensor data and/or the reader is sent to the reader. The second indication information, or the tag matching the condition directly sends the sensing data and/or the second indication information.
步骤620，标签根据第二命令，向读写器发送第五信息。相应地，读写器接收来自标签的第五信息。Step 620, the tag sends fifth information to the reader according to the second command. Accordingly, the reader/writer receives the fifth information from the tag.
其中，第五信息包括第二指示信息和/或第二传感数据。第二传感数据满足上述条件信息所指示的条件。Wherein, the fifth information includes second indication information and/or second sensing data. The second sensing data satisfies the condition indicated by the above condition information.
在一些实现方式中，在接收到第二命令后，标签确定是否满足条件信息所指示的条件。若确定满足条件信息所指示的条件，标签向读写器发送第五信息。In some implementations, after receiving the second command, the tag determines whether the condition indicated by the condition information is satisfied. If it is determined that the condition indicated by the condition information is satisfied, the tag sends fifth information to the reader.
作为一个示例，标签根据第二命令中的阈值信息，确定第二传感数据是否异常。例如，标签在第二传感数据的数值大于第一阈值时，确定第二传感数据异常。又例如，标签在第二传感数据的数值小于第二阈值时，确定第二传感数据异常。又例如，标签在第二传感数据的数值大于第一阈值且小于第二阈值时，确定第二传感数据异常。这里的第二传感数据可以是最近一次或者n次的记录。As an example, the tag determines whether the second sensing data is abnormal according to the threshold information in the second command. For example, when the value of the second sensing data is greater than the first threshold, the tag determines that the second sensing data is abnormal. For another example, when the value of the second sensing data is smaller than the second threshold, the tag determines that the second sensing data is abnormal. For another example, the tag determines that the second sensing data is abnormal when the value of the second sensing data is greater than the first threshold and less than the second threshold. The second sensing data here may be the most recent or n-time records.
作为另一个示例，标签根据第二命令中的标签需满足的条件，确定标签是否匹配该条件。例如，标签在该标签的标识中包含的特定比特且具备传感功能时，确定标签匹配该条件，向读写器发送第五信息。标签可以等待接入成功后向读写器发送第五信息，也可以直接发送第五信息。As another example, the tag determines whether the tag matches the condition according to the condition that the tag in the second command needs to meet. For example, when the tag has a specific bit included in the tag's identification and has a sensing function, it is determined that the tag matches the condition, and the fifth information is sent to the reader. The tag can send the fifth information to the reader after the access is successful, or can directly send the fifth information.
若第二命令中没有包含阈值信息，可以使用默认的阈值，如第一阈值或者第二阈值。则当标签收到第二命令时，可以激活告警流程，通过与默认阈值比较判断是否上报。具体的，上报也可以为周期上报或者读写器配置上报最大次数，在最大次数内以固定周期进行上报直到达到最大次数或者读写器指示停止告警流程。If the second command does not contain threshold information, a default threshold, such as the first threshold or the second threshold, may be used. Then, when the tag receives the second command, it can activate the alarm process, and judge whether to report by comparing with the default threshold. Specifically, the reporting may also be periodic reporting or the reader configures the maximum number of reports, and within the maximum number of times, the reporting is performed at a fixed period until the maximum number is reached or the reader instructs the reader to stop the alarm process.
可选地，第五信息可以只有1比特用于指示存在异常数据。Optionally, the fifth information may have only 1 bit for indicating the existence of abnormal data.
可选地，第五信息也可以包括传感数据的类型和异常指示，异常指示用于指示存在异常数据。Optionally, the fifth information may also include the type of the sensing data and an abnormality indication, where the abnormality indication is used to indicate that abnormal data exists.
可选地，第五信息可以与EPC一起发送，或者在标签的接入过程中与随机数或者标 签标识一起进行上报，上报方式不限。Optionally, the fifth information can be sent together with the EPC, or reported together with the random number or the label identifier during the access process of the label, and the reporting method is not limited.
此外，若标签上报第五信息后若出现碰撞，则读写器发送信令，初始化新一轮标签接入。In addition, if a collision occurs after the tag reports the fifth information, the reader will send signaling to initiate a new round of tag access.
在另一些实现方式中，可以由标签主动发送第五信息。In other implementations, the fifth information may be actively sent by the tag.
示例性地，可以在标签中为每个传感数据预配置阈值信息，标签根据预配置的阈值信息，确定传感数据是否异常。该预配置的阈值信息可以保存在内存中，如上文中5个存储区中。阈值信息可以是读写器、核心网设备或者服务器向标签分配的。当标签判断传感数据存在异常时可以触发主动上报，上报方式可以参考步骤620的描述，在此不再赘述。Exemplarily, threshold information may be preconfigured in the tag for each sensing data, and the tag determines whether the sensing data is abnormal according to the preconfigured threshold information. The preconfigured threshold information can be stored in the memory, such as the five storage areas above. The threshold information can be assigned to the tag by the reader, core network device or server. When the tag determines that the sensor data is abnormal, it can trigger an active report, and the report method can refer to the description of step 620, which will not be repeated here.
需要说明的是，在一些实现方式中，第二命令可以为第一命令，第一传感数据可以为第二传感数据，第一信息可以为第六信息，第二信息可以为第七信息。It should be noted that, in some implementation manners, the second command may be the first command, the first sensing data may be the second sensing data, the first information may be the sixth information, and the second information may be the seventh information .

需要说明的是，若标签从读写器收到第一命令或者第二命令时，若标签没有传感数据可以发送至读写器，则可以发送一条指示信息，用于指示无数据可上报或错误指示。It should be noted that when the tag receives the first command or the second command from the reader, if the tag has no sensor data that can be sent to the reader, an indication message can be sent to indicate that there is no data to report or Error indication.
