Description
本发明涉及数据通信技术领域，具体涉及数据接收处理方法及装置。
数据通信主要是指通过数据通信设备和通信信道等实现不同数据终端设备之间的数据传输，其中，数据通常是以数据帧(由字节封装而成，每个字节由多位数据组成)的形式进行传输。在强干扰环境(如高噪声、高电磁干扰等)下进行数据通信时，通信信道中传输的数据帧可能会由于干扰发生位反转(例如，一个或多个数据位的数据由“0”反转为“1”)，若接收侧的数据终端设备无法及时甄别数据的准确性，将会极大影响数据通信的可靠性。为此，当前主要是通过在数据帧的帧尾增加校验和字节(Checksum)(例如，判断在数据发送与接收侧，数据帧中数据位的数据累加和是否一致)来检验数据帧是否发生异常。但是，这种检验方式仍然存在一定的误检概率，例如，当数据帧中有两个数据位发生位反转且这两个数据位的原数据分别是0和1时，数据帧的数据位累加和不会发生改变，即通过比较校验和仍无法准确检验出错误数据。
相应地，本领域需要一种新的数据处理方案来解决上述问题。

下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。
下面结合附图对本发明实施例提供的一种数据接收处理方法进行说明。参阅附图1，图1示例性示出了本发明实施例中一种数据接收处理方法的主要步骤。如图1所示，本发明实施例中数据接收处理方法主要包括以下步骤：
步骤S101：分别获取接收到的当前数据帧和目标数据帧中特定数据位的数据。
在本实施例中数据发送侧的数据终端设备(为描述简洁，在本实施例中简称为发送侧设备)向数据接收侧的数据终端设备(为描述简洁，在本实施例中简称为接收侧设备)发送通信数据时，通信数据以数据帧为单位一帧一帧地传输，接收侧设备也会一帧一帧地接收通信数据。本实施例中的当前数据帧指的是在当前时刻接收侧设备接收到的数据帧，目标数据帧指的是接收侧设备已经接收到的所有数据帧中与当前数据帧相邻的数据帧，而相邻的数据帧可以理解为接收侧设备在接收当前数据帧之前，最新接收到的一个或几个数据帧。
在本实施例中特定数据位指的是数据帧中数据调整频率小于等于预设调整频率的数据位。例如，本实施例中特定数据位可以是表示发送侧设备身份信息(设备身份信息应当保持长期不变)的数据所在的数据位，还可以是表示发送侧设备的指令信息(如控制接收侧设备执行某个动作的指令，或控制接收侧设备向发送侧设备上报某种信息的指令等一定时间内保持不变的指令)等其他数据调整频率小于等于预设调整频率的数据所在的数据位。可选的，本实施例中特定数据位可以是多个，例如特定数据位可以是数据帧中某个字节的8位数据位，也可是不同字节中不同数据位的组合。
步骤S102：比较当前数据帧和目标数据帧中特定数据位的数据是否一致。具体地，在本实施例中若当前数据帧和目标数据帧中特定数据位的数据一致(例如，特定数据位的数据均是1)，则转至步骤S103；若当 前数据帧和目标数据帧中特定数据位的数据不一致(例如，当前数据帧中特定数据位的数据是1，而目标数据帧中特定数据位的数据是0)，则转至步骤S104；
步骤S103：解析当前数据帧。
在本实施例中若当前数据帧和目标数据帧中特定数据位的数据一致时，表明当前数据帧中的数据没有由于环境干扰或其他原因发生位反转，即当前数据帧是正确的数据帧，可以直接解析当前数据帧。
步骤S104：继续解析上一个被解析的数据帧。
在本实施例中若当前数据帧和目标数据帧中特定数据位的数据不一致时，表明当前数据帧中的数据有可能是发送侧设备的指令信息等发生了改变，也可能由于环境干扰或其他原因发生了位反转。综上所述，为了避免解析错误数据而发生误操作，需要在“当前数据帧和目标数据帧中特定数据位的数据不一致”的情况下，继续解析上一个被解析的数据帧，即继续解析上一个正确的数据帧。
下面结合本发明实施例中的一个具体实施方案对图1所示的数据接收处理方法作进一步说明。
在本实施方案中发送侧设备向接收侧设备发送的通信数据中每个数据帧的特定数据位是数据帧中的第1个字节，即字节1；目标数据帧是接收侧设备当前接收到的数据帧的上一个数据帧，即目标数据帧是接收侧设备已经接收到的数据帧中与当前数据帧相邻的第1个数据帧。

下面结合本发明实施例中的另一个具体实施方案对图1所示的数据接收处理方法作进一步说明。
在本实施方案中发送侧设备向接收侧设备发送的通信数据中每个数据帧的特定数据位是数据帧中的第1个字节，即字节1；目标数据帧是在接收侧设备当前接收到的数据帧之前最新接收到的两个数据帧，即目标数据帧是接收侧设备已经接收到的数据帧中与当前数据帧相邻的第1-2个数据帧。
1、接收侧设备当前接收到了第m个数据帧TX

m-2；通过数据比较，确定数据帧TX

2、接收侧设备当前接收到了第m+1个数据帧TX

m+2相邻的数据帧TX
m+1和数据帧TX
m；通过数据比较，确定数据帧TX
m+2与数据帧TX
m+1字节1一致，和数据帧TX
m中字节1的数据不一致，则继续解析数据帧TX
m；
4、接收侧设备当前接收到了第m+3个数据帧TX
m+3，即目标数据帧是与数据帧TX
m+3相邻的数据帧TX
m+2和数据帧TX
m+1；通过数据比较，确定数据帧TX
m+3、数据帧TX
m+2和数据帧TX
m+1中字节1的数据均一致，则直接解析数据帧TX
m+3。
在本发明实施例中，通过获取当前数据帧和目标数据帧中特定数据位的数据并且比较特定数据的数据是否一致，来判断当前数据帧的准确性，显著提高了发送侧设备与接收侧设备之间的通信可靠性。
进一步地，在本发明的一个可选实施例中，还可以按照以下步骤进行数据接收处理：
步骤S201：判断当前数据帧的计算校验和与当前接收到的实际校验和是否一致。具体地，在本实施例中若当前数据帧的计算校验和与实际校验和一致，则转至步骤S202；若当前数据帧的计算校验和与实际校验和不一致，则判定当前数据帧是错误的数据帧。
在本实施例中当前数据帧的计算校验和指的是利用预设的校验和算法并根据当前数据帧中数据位的数据，计算得到的当前数据帧的校验和，实际校验和指的是当前实际接收到的校验和。同时，在本实施例中预设校验和算法应当与实际校验和使用的校验和算法相同。可选的，实际校验和使用的校验和算法可以是累加和算法或CRC(Cyclic Redundancy Check)校验算法等。
步骤S202：分别获取接收到的当前数据帧和目标数据帧中特定数据位的数据。
步骤S203：比较当前数据帧和目标数据帧中特定数据位的数据。具体地，在本实施例中若当前数据帧和目标数据帧中特定数据位的数据一致，则转至步骤S204；若当前数据帧和目标数据帧中特定数据位的数据不一致，则转至步骤S205。
步骤S204：解析当前数据帧。
步骤S205：继续解析上一个被解析的数据帧。
要说明的是，本实施例中的步骤S202、步骤S203、步骤S204和步骤S205的具体实施方案分别与前述实施例中的步骤S101、步骤S102、步骤S103和步骤S104的具体实施方案的相同，为了描述简洁，在此不再赘述。
在本发明实施例中，首先通过比较“当前数据帧的计算校验和”以及“当前接收到的实际校验和”是否一致的方式判断当前数据帧的准确性，进而再通过获取当前数据帧和目标数据帧中特定数据位的数据并且比较特定数据的数据是否一致，来判断当前数据帧的准确性，能够进一步提高发送侧设备与接收侧设备之间的通信可靠性。
上述实施例中虽然将各个步骤按照上述先后次序的方式进行了描述，但是本领域技术人员可以理解，为了实现本实施例的效果，不同的步骤之间不必按照这样的次序执行，其可以同时(并行)执行或以颠倒的次序执行，这些简单的变化都在本发明的保护范围之内。
基于上述方法实施例所述的数据接收处理方法，本发明实施例还提供了一种数据接收处理装置，下面结合附图对本发明实施例中的数据接收处理装置进行具体说明。
参阅附图2，图2示例性示出了本发明实施例中数据接收处理装置的主要结构。如图2所示，本发明实施例中数据接收处理装置主要包括 数据获取模块11和数据解析模块12。具体而言，数据获取模块11可以被配置成分别获取接收到的当前数据帧和目标数据帧中特定数据位的数据；数据解析模块12可以被配置成比较所述特定数据位的数据是否一致：若一致，则解析当前数据帧；若不一致，则继续解析上一个被解析的数据帧；其中，目标数据帧是已接收到的数据帧中与当前数据帧相邻的数据帧，特定数据位是数据帧中数据调整频率小于等于预设调整频率的数据位。可选的，本发明实施例中目标数据帧的数量可以是一个或多个，特定数据位的数量可以是多个。
进一步地，在本发明实施例的一个可选实施方案中，图2所示的数据接收处理装置还可以包括数据校验模块，该数据校验模块可以被配置成判断当前数据帧的计算校验和与当前接收到的实际校验和是否一致：若一致，则启动数据获取模块11和数据解析模块12，即在判断出当前数据帧的计算校验和与实际校验和一致后，再启动数据获取模块11和数据解析模块12，使二者分别执行各自的操作。
可选的，在本实施方案中数据校验模块可以进一步被配置成利用预设的校验和算法并根据当前数据帧中数据位的数据，计算当前数据帧的计算校验和；其中，预设的校验和算法与实际校验和使用的校验和算法相同。
要说明的是，上述数据接收处理装置实施例以用于执行上述数据接收处理方法实施例，其技术原理、所解决的技术问题及产生的技术效果相似，所属技术领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述数据接收处理装置实施例的具体工作过程及有关说明，可以参考前述数据接收处理方法实施例中的对应过程，在此不再赘述。
本领域技术人员能够理解，上述数据接收处理装置还包括一些其他公知结构，例如处理器、控制器、存储器等，其中，存储器包括但不限于随机存储器、闪存、只读存储器、可编程只读存储器、易失性存储器、非易失性存储器、串行存储器、并行存储器或寄存器等，处理器包括但不限于CPLD/FPGA、DSP、ARM处理器、MIPS处理器等，为了不必要地模糊本公开的实施例，这些公知的结构未在图2中示出。
应该理解，图2中的各个模块的数量仅仅是示意性的。根据实际需要，各模块可以具有任意的数量。
本发明还可以实现为用于执行这里所描述的方法的一部分或者全部的设备或者装置程序(例如，PC程序和PC程序产品)。这样的实现 本发明的程序可以存储在PC可读介质上，或者可以具有一个或者多个信号的形式。这样的信号可以从因特网网站上下载得到，或者在载体信号上提供，或者以任何其他形式提供。
应该注意的是上述实施例对本发明进行说明而不是对本发明进行限制，并且本领域技术人员在不脱离所附权利要求的范围的情况下可设计出替换实施例。在权利要求中，单词“包括”不排除存在未列在权利要求中的元件或步骤。本发明可以借助于包括有若干不同元件的硬件以及借助于适当编程的PC来实现。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
