Description

一种数据读取方法、装置、计量设备和服务器 技术领域
本说明书实施例方案属于数据处理的技术领域，特别涉及一种数据读取方法、装置、计量设备和服务器。
背景技术
计量表的读数可以为相关部门收费和调配资源等提供重要参考。许多地区获取计量表的读数均以传统手工抄表方式为主，然而手工抄表方式不仅需要工作人员亲自入户抄表，而且可能需要光线以及爬高，这样就会造成工作量大、工作效率低下等问题。
随着科学技术的发展，传统人工逐户抄表的方式逐渐被自动抄表所取代。自动抄表无需人工参与，其主要是通过与计量表相连接的采集器获取计量表的读数，然后采集器将获取的读数发送至集中器，集中器将所管辖的计量表的读数进行汇总后发送到数据管理中心。可见，自动抄表可一次抄读多个用户的电表、水表、气表、热量表等计量表的信息，抄表快捷方便。然而，自动抄表过程中，采集器将获取的数据发送至集中器以及集中器将汇总后的计量表的读数发送到数据管理中心时都可能会被恶意篡改，导致最终获取的数据不是真实数据。
因此，业内亟需一种可以高效的、安全的获取计量表数据的解决方案。

S10：获取计量设备上的计量数据，基于所述计量数据、识别标识以及第一时间戳生成第一加密数据，所述第一时间戳包括计量设备获取所述计量数据时所对应的时间。
所述计量设备可以包括需要读取自身数据的设备，如水表、电表或者燃气表等。所述计量设备可以包括通信模块，可以与终端设备通过蓝牙或WiFi进行连接和数据传输，也可以与远程的服务器进行通信连接，实现与所述服务器的数据传输。所述计量数据包括所述计量设备上需要读取的数据，如用水量、用电度数、所用燃气量等。所述识别标识可以包括用来区分不同设备的标识(以下可以简称为“设备唯一标识”)、设备编号等。时间戳可以唯一标识某一刻的时间。所述第一时间戳可以包括计量设备获取计量数据时所对应的时间。需要说明的是，同一设备的设备唯一标识可以保持不变，设备编号可以更改。
本说明书一个实施例中，所述计量设备可以包括广播固件、加密模块以及数据读取模块。其中，所述数据读取模块可以用来获取计量设备当前数据(如，计量数据、时间戳等)。所述加密模块可以用来对所述数据模块读取的数据进行加密处理。所述广播固件可以用来对所述加密模块处理后的数据进行广播，所述广播固件可以是BLE(Bluetooth Low Energy，蓝牙低能耗)广播固件或者WiFi固件等。所述加密处理算法可以包括一次性密码(One-time Password，OTP)算法、基于散列消息身份验证码(Hashed Message Authentication Code，HMAC)算法加密的一次性密码(HMAC-based One-Time Password，HOTP)算法等。一些实施场景中，OTP、HOTP等算法可以根据专门的算法每隔一段时间生成一个与时间相关的、不可预测的随机数字组合，每个口令只能使用一次。一些实施场景中，OTP、HOTP可以包括时间窗口机制，通过OTP、HOTP进行加密后的信息，在预设时间段内有效，超过预设时间段失效。
需要说明的是，一些实施场景中，计量数据可以通过计量设备包括的数据读取模块获取，还可以通过智能芯片获取，也可以通过安装有智能芯片的计量设备获取，还可以通过其他方式获取。本说明书实施例以及附图中以计量设备获取自身计量数据为例进行示意性说明，其它方式类似，对此不作赘述。
本说明书实施例中，为了安全有效地将计量设备的计量数据提供给上述服务器，以便服务器准确地记录计量数据，并根据记录的计量数据准确统计各户业主家的用度情况，每个计量设备可以分别读取自身的计量数据，然后根据自身的识别标识中包括的设备唯一标识、计量数据和读取计量数据时所对应的时间，生成相应的加密数据。
一些实施场景中，所述计量设备可以为电表。例如，在一个小区的某栋楼里有多户业主，每户业主家分别对应一个电表，该电表包括BLE广播固件、OTP加密模块以及数据读取模块。当工作人员需要获取当前电表数据时，工作人员可以在计量设备预设距离范围内触发移动终端上指定应用的匹配指令向电表发送获取当前电表数据的请求，电表收到该请求后，可以通过数据读取模块获取当前电表读数和对应时间，然后通过OTP加密模块将电表读数、电表的唯一标识以及对应时间生成第一加密数据。由于在生成对应的第一加密数据时，所依据的电表数据是直接读取的，所以可以保证该电表数据是真实的。
需要说明的是，由于所述信标信息的识别标识中不仅可以包括用来区分不同设备的唯一标识，而且也可以包括设备编号。所以一些实施例中，为了防止传输数据被恶意篡改、保证传输数据的安全性，计量设备对获取的数据进行加密处理时，可以使用识别标识中包括的设备的唯一标识。一些实施场景中，计量设备、终端设备、服务器之间可以进行实时通信，这样，在计量设备获取计量数据时，终端设备和服务器可以获取对应的时间并保存。需要说明的是，终端设备和服务器获取对应时间可以通过本领域人员知晓的任意一种方式，本说明书对此不作限定。
S12：所述计量设备发送信标信息至终端设备，所述信标信息包括所述计量数据、所述第一加密数据以及所述识别标识。
所述识别标识可以包括设备唯一标识、设备编号等。
本说明书一个实施例中，所述计量设备在生成各自对应的第一加密数据之后，可以通过自带的蓝牙或者WiFi网络将计量数据、加密数据以及识别标识广播出去。
本说明书一个实施例中，所述计量设备发送信标信息至终端设备可以包括：所述终端设备在计量设备预设距离范围内和/或基于触发终端上指定应用的匹配指令时，建立所述计量设备与所述终端设备的通信连接；所述计量设备将所述信标信息发送至所述终端设备。所述计量设备与所述终端设备建立通信连接的条件可以包括终端设备在计量设备预设距离范围内或触发了终端设备上指定应用的匹配指令或终端设备在计量设备预设距离范围内且触发了终端上指定应用的匹配指令等。需要说明的是，建立通信连接的条件还可以包括其他条件，本说明书对此不作限定。
例如一个实施场景中，抄表工作人员可以启动所使用的智能手机上的计量app(Application)，然后通过点击该计量app上的“数据接收”控件与计量设备建立通信 连接，从而可以接收计量设备广播的信息。另一个实施场景中，抄表工作人员可以在计量设备预设距离范围内启动所使用的智能手机上的计量app(Application)，然后通过点击该计量app上的“数据接收”控件与计量设备建立通信连接，从而可以接收计量设备广播的信息。
一些实施例中，终端设备在接收到计量数据、加密数据以及识别标识后，可以对接收到的信息进行汇总。例如，抄表工作人员启动所使用的智能手机上的计量app，并点击该计量app上的“数据接收”控件与计量设备建立通信连接并接收到各个计量设备广播的信息后，可以将接收到的信息进行汇总。例如一些实施场景中，终端设备在接收到计量数据、加密数据以及识别标识后，可以按照时间区间进行汇总，也可以按照计量设备对应的位置信息进行汇总，还可以按照数量进行汇总等。例如，终端设备在接收到计量数据、加密数据以及识别标识后，可以将属于同一个小区的信息进行汇总，也可以当接收到的信息满100个时汇总一次，还可以将一周内接收到的信息进行汇总等。
需要说明的是，由于所述信标信息的识别标识中不仅可以包括用来区分不同设备的唯一标识，而且也可以包括设备编号等。所以一些实施例中，为了防止传输数据被恶意篡改、保证传输数据的安全性，计量设备在进行广播时，所述信标信息中包括的识别标识是设备编号。此外，上述计量设备进行广播的信息包括计量数据、第一加密数据以及设备编号只是进行示例性说明，所述计量设备进行广播的信息还可以包括其他信息，本说明书对此不做限定。
S20：所述终端设备将所述信标信息发送至服务器。
本说明书一个实施例中，计量设备发送信标信息至终端设备后，所述终端设备可以将所述信标信息进行汇总后发送至服务器。一些实施例中，终端设备可以在达到预设的发送要求时，将所述信标信息发送至服务器。所述预设的发送要求可以包括终端设备接收到的信标信息的数量达到预设数量，或者终端设备接收到一个向服务器发送一个，或者终端设备对所有信标信息校验通过后才发送，或者是定时发送，如一个小时发一次等。
本说明书一个实施例中，所述终端设备可以为移动终端，相应的，所述将所述信标信息发送至终端设备，所述终端设备将所述信标信息发送至服务器可以包括：所述移动终端在计量设备预设距离范围内和/或基于触发移动终端上指定应用的匹配指令时，建立所述计量设备与所述移动终端的通信连接；所述计量设备将所述信标信息发送至所述移动终端；所述移动终端在达到预设的发送要求时，将所述信标信息发送至服务器。

本说明书提供的另一个实施例中，所述终端设备可以预先存储上述各个计量设备的相关信息，如识别标识，其中预先存储的识别标识中的设备编号与设备唯一标识可以预先设置为相互关联。所述终端设备在接收到所述信标信息后，还可以包括：S200：基于所述计量数据、识别标识以及接收到所述信标信息时对应的第三时间戳生成第三加密数据；S202：比较所述第三加密数据与所述第一加密数据，在比较结果符合记录要求时记录所述计量数据。
一些实施例中，所述信标信息可以包括所述计量数据、所述第一加密数据以及所述识别标识。另一些实施例中，所述信标信息中除了可以包括计量数据、第一加密数据以及识别标识外，还可以包括其他信息，如第三加密数据。一些实施例中，符合记录要求可以包括比较结果在预设误差范围内，或者比较结果相同，或者其它等。
为了提高数据传输的安全性，在一些实施例中，当所述终端设备接收到的信息包括计量数据、第一加密数据以及识别标识中的设备编号时，所述终端设备可以在预先存储的信息中查找与所述设备编号对应的设备，并获取该设备的唯一标识，通过加密方法对计量数据、设备的唯一标识以及接收到所述信标信息时对应的第三时间戳进行加密，获得第三加密信息，然后终端设备将第三加密数据与第一加密数据进行比较，在比较结果符合记录要求时，表明接收到的该计量设备的计量数据与生成第一加密数据时所依据的计量数据相同，从而可以表明接收到的该计量设备的计量数据是真实的，最后可以将计量数据、识别标识、第一加密数据发送至服务器，从而提高数据传输的安全性。
另一些实施例中，当所述终端设备接收到的信息包括计量数据、第一加密数据以及识别标识中的设备编号时，所述终端设备可以在预先存储的信息中查找与所述设备编号对应的设备，并获取该设备的唯一标识，通过加密方法对计量数据、设备的唯一标识以及接收到所述信标信息时对应的第三时间戳进行加密，获得第三加密信息，然后终端设备将第三加密数据与第一加密数据进行比较，在比较结果不符合记录要求时，表明接收到的该计量设备的计量数据与生成第一加密数据时所依据的计量数据不相同，从而可以表明接收到的该计量设备的计量数据是不真实的，此时可以将不真实情况反馈至相关技术人员，以加强数据传输过程安全性。
在另一些实施例中，当所述终端设备接收到的信息包括计量数据、第一加密数据以及识别标识中的设备编号时，所述终端设备可以在预先存储的信息中查找与所述设备编号对应的设备，并获取该设备的唯一标识，通过加密方法对计量数据、设备的唯一标识以及接收到所述信标信息时对应的第三时间戳进行加密，获得第三加密信息，然后将计量数据、识别标识、第一加密数据以及第三加密数据发送至服务器，以便服务器进行进一步的验证，从而提高数据传输的安全性。
需要说明的是，一些实施例中，第三时间戳可以为终端设备接收到信标信息时对应的时间。第三时间戳与生成第一加密数据时所用的第一时间戳可以在同一时间窗口或者预设的时间窗口期。例如，预先设置的时间窗口为60秒，生成第一加密数据时所用的时间为16时12分24秒，则第三时间戳可以在16时12分24秒到16时13分24秒之间。
需要说明的是，上述加密方法可以与计量设备采用的加密方法相同，也可以是与计量设备所采用的加密方法不同的方法，本说明书对此不作限定。
S30：所述服务器基于所述识别标识、所述计量数据以及接收到所述信标信息时对应的第二时间戳生成第二加密数据。
一些实施例中，所述第二时间戳与所述第一时间戳可以在同一时间窗口或预设的时间窗口内。
本说明书一个实施例中，所述服务器可以预先存储各个计量设备的识别标识。所述识别标识可以包括设备唯一标识、设备编号等。其中，设备编号与设备唯一标识可以预先相互关联。第二时间戳可以包括服务器接收到信标信息时对应的时间。时间窗口可以表示一个预设时间段。所述第二时间戳与所述第一时间戳在同一时间窗口可以理解为：以第一时间戳为起始时间，起始时间与预设时间段之和为终止时间，第二时间戳可以在起始时间与终止时间之间。一些实施例中，所述第二时间戳与所述第一时间戳在同一时间窗口，可以防止数据被篡改。
本说明书一个实施例中，由于在信息广播和数据传输过程中，可能会存在计量数据被恶意虚构或篡改的情况，所以，服务器在接收到信标信息之后，可以通过加密算法对计量数据、识别标识中的设备唯一标识以及对应时间进行加密，获得加密数据。
一些实施例中，由于所述服务器接收到的识别标识中包括设备编号，所以为了保证数据的安全，可以获得与设备编号对应的设备唯一标识。例如一些实施场景中，所述服 务器可以预先存储各个计量设备的识别标识，且识别标识中包括的设备编号与设备唯一标识相互关联，服务器接收到的识别标识中包括设备编号时，可以根据所述信标信息中包括的设备编号在服务器中查找对应的设备唯一标识，然后通过加密算法对计量数据、查找到的设备唯一标识以及对应时间进行加密，获得第二加密数据。
另一些实施例中，为了保证数据的安全，服务器在接收到所述信标信息之后，可以先根据所述识别标识中的设备编号在服务器中查找对应的设备唯一标识，然后将查找到的设备唯一标识与接收到的信标信息中包括的设备唯一标识进行比较，若二者相同，再通过加密算法对计量数据、识别标识中的设备唯一标识以及对应时间进行加密，获得第二加密数据。一些实施例中，若查找到的设备唯一标识与接收到的信标信息中包括的设备唯一标识不相同，则可以反馈至相关技术人员，以加强数据传输过程安全性。
需要说明的是，所述加密方法可以是计量设备采用的加密方法，也可以是与计量设备所采用的加密方法不同的方法，本说明书对此不作限定。
S32：所述服务器比较所述第二加密数据与所述第一加密数据，在比较结果符合记录要求时记录所述计量数据。
一些实施例中，所述服务器在生成第二加密数据后，会将其与之前接收到的加密数据进行比较，以确定所接收到的计量数据是否被篡改，从而提高数据传输的安全性。其中，符合记录要求可以包括比较结果在预设误差范围内，或者比较结果相同，或者其它要求等。
本说明书一个实施例中，当服务器接收到信标信息并基于相关信息生成第二加密数据后，可以将所述第二加密数据与接收到的信标信息中包括的第一加密数据进行比较。若比较结果符合记录要求，表明接收到的该计量设备的计量数据与生成第一加密数据时所依据的计量数据相同，从而可以表明接收到的该计量设备的计量数据是真实的，服务器可以记录该计量设备的计量数据。否则，表明接收到的计量设备的计量数据与生成第一加密数据时所依据的计量数据并不相同，从而可以表明接收到的该计量设备的计量数据可能在前期的数据传输过程中被恶意虚构或篡改了，是不真实的。
一些实施例中，当服务器接收到计量数据、识别标识、第一加密数据以及第三加密数据时，可以将所述第二加密数据与接收到的第一加密数据、第三加密数据进行比较。当第二加密数据、第一加密数据、第三加密数据的比较结果符合记录要求时，表明接收到的该计量设备的计量数据与生成第一加密数据时所依据的计量数据相同，从而可以表 明接收到的该计量设备的计量数据是真实的，服务器可以记录该计量设备的计量数据。
需要说明的是，当出现接收到的该计量设备的计量数据可能在前期的数据传输过程中被恶意虚构或篡改的情况时，服务器可以将该不真实的情况反馈至相关技术人员，以加强数据传输过程安全性。这样，无需抄表人员肉眼观测，便可以获取各个计量设备的计量数据，还可以保证服务器记录的数据的真实性。
本说明书还提供另一种场景示例。例如，实际应用过程中，在一个小区的某栋楼里有多户业主，每户业主家分别对应一个计量设备，在该栋楼可以设置一个智能总表。各个计量设备在读取各自的计量数据并生成对应的第一加密数据之后可以通过蓝牙的方式进行广播，智能总表通过扫描并接收该计量设备广播的信息后可以进行汇总，然后通过与服务器建立的通信连接将汇总信息发送至服务器，服务器通过对接收到的信息进行验证，从而可以获得计量设备的真实数据。这样，无需抄表人员肉眼观测或上门观测，便可以获取各个计量设备的计量数据，保证服务器记录的数据的真实性。其中，计量设备以及智能总表可以包括蓝牙模块和/或WiFi模块，计量设备与智能总表之间可以通过蓝牙或者WiFi网络进行连接和数据传输，且计量设备处于从模式用来广播信息。此外，智能总表还可以包括远程通信模块，可以与远程的服务器进行通信连接，实现与服务器的数据传输。

上述对本说明书特定实施例进行了描述。其它实施例在所附权利要求书的范围内。在一些情况下，在权利要求书中记载的动作或步骤可以按照不同于实施例中的顺序来执行并且仍然可以实现期望的结果。另外，在附图中描绘的过程不一定要求示出的特定顺序或者连续顺序才能实现期望的结果。在某些实施方式中，多任务处理和并行处理也是可以的或者可能是有利的。
本说明书实施例提供的一种数据读取的计量设备或服务器，计量设备可以将自身的计量数据加密后通过蓝牙的方式进行广播，服务器在收到信息后，基于相应的信息进行加密，并将加密数据与接收到的加密数据进行比较。这样，无需抄表人员肉眼观测或上门观测，便可以获取各个计量设备的计量数据，从而可以保证服务器记录的数据的真实性的同时，可以有效解决数据传输过程中被恶意篡改的问题，提高数据读取的安全性。
当然，上述实施例的实施方案还可以用于其它需要获取自身数据的应用场景中。
虽然本申请提供了如实施例或流程图所述的方法操作步骤，但基于常规或者无创造性的劳动可以包括更多或者更少的操作步骤。实施例中列举的步骤顺序仅仅为众多步骤执行顺序中的一种方式，不代表唯一的执行顺序。在实际中的装置或计量设备产品执行时，可以按照实施例或者附图所示的方法顺序执行或者并行执行(例如并行处理器或者多线程处理的环境)。
尽管本说明书实施例内容中提到计量设备/终端设备/服务器的交互方式、计量设备/服务器的交互方式、加密算法、信息广播等之类的数据获取、交互、处理、比较等操作和数据描述，但是，本说明书实施例并不局限于必须是符合行业通信标准、标准图像数据处理协议、通信协议和标准数据模型/模板或本说明书实施例所描述的情况。某些行业标准或者使用自定义方式或实施例描述的实施基础上略加修改后的实施方案也可以实现上述实施例相同、等同或相近、或变形后可预料的实施效果。应用这些修改或变形后的数据获取、存储、判断、处理方式等获取的实施例，仍然可以属于本说明书的可选实施方案范围之内。
在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的 改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字系统“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。
上述实施例阐明的系统、装置、模块或单元，具体可以由计算机芯片或实体实 现，或者由具有某种功能的产品来实现。一种典型的实现设备为计算机。具体的，计算机例如可以为个人计算机、膝上型计算机、车载人机交互设备、蜂窝电话、相机电话、智能电话、个人数字助理、媒体播放器、导航设备、电子邮件设备、游戏控制台、平板计算机、可穿戴设备或者这些设备中的任何设备的组合。
虽然本说明书实施例提供了如实施例或流程图所述的方法操作步骤，但基于常规或者无创造性的手段可以包括更多或者更少的操作步骤。实施例中列举的步骤顺序仅仅为众多步骤执行顺序中的一种方式，不代表唯一的执行顺序。在实际中的装置或终端产品执行时，可以按照实施例或者附图所示的方法顺序执行或者并行执行(例如并行处理器或者多线程处理的环境，甚至为分布式数据处理环境)。术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、产品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、产品或者设备所固有的要素。在没有更多限制的情况下，并不排除在包括所述要素的过程、方法、产品或者设备中还存在另外的相同或等同要素。
为了描述的方便，描述以上装置时以功能分为各种模块分别描述。当然，在实施本说明书实施例时可以把各模块的功能在同一个或多个软件和/或硬件中实现，也可以将实现同一功能的模块由多个子模块或子单元的组合实现等。以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
本领域技术人员也知道，除了以纯计算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内部包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。
本发明是参照根据本发明实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中 的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
在一个典型的配置中，计算设备包括一个或多个处理器(CPU)、输入/输出接口、网络接口和内存。
内存可能包括计算机可读介质中的非永久性存储器，随机存取存储器(RAM)和/或非易失性内存等形式，如只读存储器(ROM)或闪存(flash RAM)。内存是计算机可读介质的示例。
计算机可读介质包括永久性和非永久性、可移动和非可移动媒体可以由任何方法或技术来实现信息存储。信息可以是计算机可读指令、数据结构、程序的模块或其他数据。计算机的存储介质的例子包括，但不限于相变内存(PRAM)、静态随机存取存储器(SRAM)、动态随机存取存储器(DRAM)、其他类型的随机存取存储器(RAM)、只读存储器(ROM)、电可擦除可编程只读存储器(EEPROM)、快闪记忆体或其他内存技术、只读光盘只读存储器(CD-ROM)、数字多功能光盘(DVD)或其他光学存储、磁盒式磁带，磁带磁磁盘存储或其他磁性存储设备或任何其他非传输介质，可用于存储可以被计算设备访问的信息。按照本文中的界定，计算机可读介质不包括暂存电脑可读媒体(transitory media)，如调制的数据信号和载波。
本领域技术人员应明白，本说明书的实施例可提供为方法、系统或计算机程序产品。因此，本说明书实施例可采用完全硬件实施例、完全软件实施例或结合软件和硬 件方面的实施例的形式。而且，本说明书实施例可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。
本说明书实施例可以在由计算机执行的计算机可执行指令的一般上下文中描述，例如程序模块。一般地，程序模块包括执行特定任务或实现特定抽象数据类型的例程、程序、对象、组件、数据结构等等。也可以在分布式计算环境中实践本说明书实施例，在这些分布式计算环境中，由通过通信网络而被连接的远程处理设备来执行任务。在分布式计算环境中，程序模块可以位于包括存储设备在内的本地和远程计算机存储介质中。
本说明书中的各个实施例均采用递进的方式描述，各个实施例之间相同相似的部分互相参见即可，每个实施例重点说明的都是与其他实施例的不同之处。尤其，对于系统实施例而言，由于其基本相似于方法实施例，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本说明书实施例的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
以上所述仅为本说明书实施例的实施例而已，并不用于限制本说明书实施例。对于本领域技术人员来说，本说明书实施例可以有各种更改和变化。凡在本说明书实施例的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本说明书实施例的权利要求范围之内。
