具体实施方式detailed description
以下通过特定的具体实例说明本发明的实施方式，本领域技术人员可由本说明书所揭露的内容轻易地了解本发明的其他优点与功效。本发明还可以通过另外不同的具体实施方式加以实施或应用，本说明书中的各项细节也可以基于不同观点与应用，在没有背离本发明的精神下进行各种修饰或改变。需说明的是，在不冲突的情况下，以下实施例及实施例中的特征可以相互组合。Embodiments of the present invention are described below through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation modes, and various modifications or changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, in the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.
基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
在现有技术中，解调器是通过利用数据中的帧计数信息来检测接收的数据是否完整，帧计数信息是在调制业务数据时添加的，与数据内容密切相关，通过对数据内容的检测来进行数据完整性分析。然而，在数据的解调过程中还会出现信噪比过低、解扰错误、帧计数错误或者未能解析帧计数信息这类解调数据出现错误的情况，此时通过帧计数信息并不能够有效的保证数据是否连续并且没有误码，从而导致了通过帧计数信息来检测的可信度不高的问题。In the prior art, the demodulator detects whether the received data is complete by using the frame count information in the data. The frame count information is added when modulating the service data and is closely related to the data content. By detecting the data content for data integrity analysis. However, in the process of data demodulation, there may be errors in the demodulated data such as low signal-to-noise ratio, descrambling error, frame count error, or failure to parse the frame count information. At this time, the frame count information does not It can effectively ensure whether the data is continuous and has no bit errors, which leads to the problem that the reliability of detection through the frame count information is not high.
此外，当解调器有时需要接收一些数据格式不明确的信号时，由于这类型信号并没有明确的数据格式，此时解调器只能完成载波同步、时钟同步，而并不能进行帧同步、解扰、译码等数据处理，因此解调器无法获取到帧计数信息，也就不能检测该类型解调数据的完整性。因此，如何避免利用数据内容来检测数据的完整性成为本领域技术人员必须要考虑的问题。In addition, when the demodulator sometimes needs to receive some signals with unclear data format, since this type of signal does not have a clear data format, the demodulator can only complete carrier synchronization and clock synchronization at this time, but cannot perform frame synchronization, Data processing such as descrambling and decoding, so the demodulator cannot obtain the frame count information, and cannot detect the integrity of this type of demodulated data. Therefore, how to avoid using data content to detect data integrity has become a problem that those skilled in the art must consider.
为了解决上述技术问题了，本发明提出了一种数据完整性检测方法、装置、设备及介质的下述实施例。In order to solve the above technical problems, the present invention proposes the following embodiments of a data integrity detection method, device, equipment and medium.
实施例1Example 1
本实施例提供的数据完整性检测方法避免了通过数据内容验证数据帧的完整性所带来的可信度不高的问题。The data integrity detection method provided in this embodiment avoids the problem of low credibility caused by verifying the integrity of the data frame through the data content.
请参照图1，图1示出了本发明实施例提供的数据完整性检测方法流程示意图，该方法应用于解调器，该解调器可以为外置式解调器、内置式解调器、ISDN调制解调器或者ADSL调制解调器，本发明实施例对此不作任何限定。数据完整性检测方法具体包括以下步骤：Please refer to FIG. 1. FIG. 1 shows a schematic flowchart of a data integrity detection method provided by an embodiment of the present invention. The method is applied to a demodulator, and the demodulator can be an external demodulator, a built-in demodulator, An ISDN modem or an ADSL modem, which is not limited in this embodiment of the present invention. The data integrity detection method specifically includes the following steps:
步骤S110、接收数据帧并将至少一个时标信息设置于数据帧中。Step S110, receiving a data frame and setting at least one piece of time stamp information in the data frame.
其中，时标信息为当前时刻的时间信息，在解调器接收到数据帧时会将时标信息添加至该数据帧中，指的说明的是，时标信息可以平均分布于数据帧中，请参考图2，图2示出了本发明实施例提供的时标信息平均分布于数据帧的示意图。如图，时标信息将整个数据帧平均分成多个小的数据帧。此外，也可以将时标信息添加在每帧数据的头部或者尾部，并伴随着解调数据输出。请参考图3，图3示出了本发明实施例提供的时标信息位于数据帧的头部的示意图。如图，时标信息位于数据帧的头部，而每个数据帧都有与其对应的时标信息。此外，将时标信息添加至数据帧的方式可以是采用与标准时间源同步的脉冲信号作为时间基准，获取累加器计数值来对数据帧上的各个点来添加时标信息。而数据帧为传输业务数据的载体，主要用来承载业务数据。Among them, the time stamp information is the time information of the current moment, and the demodulator will add the time stamp information to the data frame when it receives the data frame, which means that the time stamp information can be evenly distributed in the data frame, Please refer to FIG. 2 . FIG. 2 shows a schematic diagram in which time scale information is evenly distributed in data frames provided by an embodiment of the present invention. As shown in the figure, the time scale information divides the entire data frame into multiple small data frames on average. In addition, time stamp information can also be added to the head or tail of each frame of data, and is output along with the demodulated data. Please refer to FIG. 3 . FIG. 3 shows a schematic diagram in which time stamp information provided by an embodiment of the present invention is located at a header of a data frame. As shown in the figure, the time stamp information is located at the head of the data frame, and each data frame has its corresponding time stamp information. In addition, the method of adding time stamp information to the data frame may be to use a pulse signal synchronized with a standard time source as a time reference, and obtain the count value of the accumulator to add time stamp information to each point on the data frame. The data frame is a carrier for transmitting service data, and is mainly used to carry service data.
解调器在完成译码、解扰等所有数据处理之后，最终得到了带有时标信息的数据帧，该数据帧便是解调数据，通过对该时标信息进行处理从而完成验证解调数据的完整性的目的。After the demodulator completes all data processing such as decoding and descrambling, it finally obtains a data frame with time stamp information, which is the demodulated data. By processing the time stamp information, the demodulated data is verified. for the purpose of integrity.
步骤S120、计算数据帧的平均时标间隔。Step S120, calculating the average time scale interval of the data frame.
进一步的，平均时标间隔的计算公式为：ΔT＝L/Rb，其中，ΔT是数据帧的平均时标间隔，L是数据帧的帧长，其单位为比特(bit)，Rb是数据传输速率，其单位为比特每秒(bit/s)。Further, the calculation formula of the average time scale interval is: ΔT=L/R b , wherein, ΔT is the average time scale interval of the data frame, L is the frame length of the data frame, and its unit is bit (bit), and R b is Data transfer rate in bits per second (bit/s).
步骤S130、根据时标信息分别计算数据帧的相邻时标间隔。Step S130, respectively calculating the adjacent time scale intervals of the data frames according to the time scale information.
在得到数据帧的平均时标间隔之后，解调器便提取数据帧中的各个时标信息，再次参考图3，第一帧数据帧的时标信息记为t1，第N帧数据帧的时标信息记为tN，而第N+1帧数据帧的时标信息记为tN+1，以此类推，然后再通过提取的时标信息得出相邻数据帧的时标间隔，即相邻时标间隔，示例地，第N帧数据与第N+1帧数据的时标间隔记为ΔtN＝tN+1-tN，以此类推便能计算出所有数据帧的相邻时标间隔，本发明实施例在此不再赘述。After obtaining the average time stamp interval of the data frame, the demodulator extracts each time stamp information in the data frame, referring to Fig. 3 again, the time stamp information of the first frame data frame is marked as t 1 , and the time stamp information of the Nth frame data frame The time stamp information is marked as t N , and the time stamp information of the N+1th frame data frame is marked as t N+1 , and so on, and then the time scale interval of adjacent data frames is obtained through the extracted time scale information, That is, the interval between adjacent time scales. For example, the time mark interval between the Nth frame data and the N+1th frame data is marked as Δt N =t N+1 -t N , and by analogy, the phase of all data frames can be calculated. The adjacent time scale interval will not be described again in this embodiment of the present invention.
步骤S140、通过平均时标间隔和相邻时标间隔判断数据帧是否完整，并执行相应的操作。Step S140 , judging whether the data frame is complete according to the average time scale interval and the adjacent time scale interval, and performing corresponding operations.
解调器用来判断接收到的数据帧的完整性其实质就是比较平均时标间隔与相邻时标间隔，判断其是否符合要求，再根据判断的结果执行对应的操作，该操作可以是发送数据帧完整的信息、将数据帧发送至下一个装置或者执行下一步操作。The demodulator is used to judge the integrity of the received data frame. The essence is to compare the average time scale interval with the adjacent time scale interval, judge whether it meets the requirements, and then perform the corresponding operation according to the result of the judgment. The operation can be sending data frame complete information, send the data frame to the next device, or perform the next operation.
在图1的基础上，请参照图4，图4示出了本发明实施例提供的数据完整性检测方法中步骤S140的流程示意图。下面对步骤S140进行详细介绍，步骤S140可以包括：On the basis of FIG. 1 , please refer to FIG. 4 , which shows a schematic flowchart of step S140 in the data integrity detection method provided by the embodiment of the present invention. Step S140 is described in detail below, and step S140 may include:
步骤S141、将平均时标间隔分别与各个相邻时标间隔进行比较得到比较结果。Step S141 , comparing the average time-scale interval with each adjacent time-scale interval to obtain a comparison result.
步骤S142、根据比较结果判断数据帧是否完整，并执行相应的操作的步骤。Step S142 , judging whether the data frame is complete according to the comparison result, and performing corresponding operation steps.
在得到平均时标间隔和多个相邻时标间隔之后，将平均时标间隔ΔT与第一个相邻时标间隔Δt1相比较，比完之后再将平均时标间隔ΔT与下一个相邻时标间隔Δt2相比较，以此类推，直至与最后一个相邻时标间隔ΔtN相比较，整个过程才结束，最后得到了比较结果，该比较结果则分为两种情况，一种情况是平均时标间隔和各个相邻时标间隔均一致，此时表示接收到的数据帧未出现错误，保障了数据帧的安全性。还有一种情况是平均时标间隔与至少一个相邻时标间隔不一致，此时数据帧并不完整，在传输中出现了数据的丢失，使得数据不连续。After obtaining the average time-scale interval and multiple adjacent time-scale intervals, compare the average time-scale interval ΔT with the first adjacent time-scale interval Δt 1 , and then compare the average time-scale interval ΔT with the next phase Adjacent time scale interval Δt 2 is compared, and so on, until compared with the last adjacent time scale interval Δt N , the whole process is ended, and finally the comparison result is obtained, and the comparison result is divided into two situations, one The situation is that the average time scale interval is consistent with each adjacent time scale interval, which means that no error occurs in the received data frame, which ensures the security of the data frame. Another situation is that the average time-scale interval is inconsistent with at least one adjacent time-scale interval. At this time, the data frame is not complete, and data loss occurs during transmission, making the data discontinuous.
接下来请参照图5，图5示出了本发明实施例提供的数据完整性检测方法中步骤S142的流程示意图。Next, please refer to FIG. 5 , which shows a schematic flowchart of step S142 in the data integrity detection method provided by the embodiment of the present invention.
步骤S142-a、若比较结果为平均时标间隔与各个相邻时标间隔一致，则判断数据帧完整。Step S142-a, if the comparison result is that the average time scale interval is consistent with each adjacent time scale interval, it is determined that the data frame is complete.
若比较结果为平均时标间隔与至少一个相邻时标间隔不一致，则判断数据帧不完整，计算丢失的数据帧并将所有丢失的数据帧累加。If the comparison result is that the average time-scale interval is inconsistent with at least one adjacent time-scale interval, it is judged that the data frame is incomplete, and the lost data frames are calculated and all the lost data frames are accumulated.
在解调器得到数据的比较结果之后，会对比较结果做一个评估，而数据完整性的表现则是平均时标间隔与各个相邻时标间隔全部一致，此时整个数据帧才是完整并且连续的数据帧，然而只要有一个相邻时标间隔与平均时标间隔匹配不上，就会被解调器认为数据帧不完整、出现了丢失的情况，此时数据帧会统计有多少个相邻时标间隔与平均时标间隔匹配不上，并且将匹配不上的数据帧进行累加，将累加过后的数据发送给工作人员看，这样便能够准确统计整个数据帧中丢失数据帧数量。After the demodulator gets the comparison result of the data, it will make an evaluation of the comparison result, and the performance of data integrity is that the average time scale interval is consistent with each adjacent time scale interval, at this time the entire data frame is complete and Continuous data frames, however, as long as there is an adjacent time scale interval that does not match the average time scale interval, it will be considered by the demodulator to be incomplete and lost. At this time, the data frame will count how many Adjacent time scale intervals do not match the average time scale interval, and the data frames that do not match are accumulated, and the accumulated data is sent to the staff for viewing, so that the number of missing data frames in the entire data frame can be accurately counted.
丢失的数据帧的计算公式为MN＝(ΔtN-ΔT)/ΔT，The formula for calculating the lost data frame is M N =(Δt N -ΔT)/ΔT,
其中，ΔT是数据帧的平均时标间隔，ΔtN是数据帧的第N帧与第N+1帧的时标信息的间隔，MN是丢失的数据帧。将所有的丢失数据帧数量累积相加，即可得到整段数据的总丢失数据帧数量。Wherein, ΔT is the average time stamp interval of the data frame, Δt N is the interval between the time stamp information of the Nth frame and the N+1th frame of the data frame, and M N is the lost data frame. The total number of lost data frames of the entire piece of data can be obtained by accumulating and adding up the numbers of all lost data frames.
本发明公开了一种数据完整性检测方法，首先解调器接收带有至少一个时标信息的数据帧，然后再计算出整个数据帧的平均时标间隔，同时根据数据帧的相邻的时标信息分别计算相邻时标间隔，最后根据平均时标间隔和相邻时标间隔来判断接收到的数据帧是否完整，并执行相应操作。该方法利用数据帧的时标信息来得出相邻时标间隔的方式判断数据帧的完整性，避免了现有技术中利用数据内容验证完整性所带来的可信度不高的问题，同时该方法也能够适用于更多的场景，扩大了检测数据完整性的使用范围。The invention discloses a data integrity detection method. First, a demodulator receives a data frame with at least one time scale information, and then calculates the average time scale interval of the entire data frame, and at the same time, according to the adjacent time scale information of the data frame The adjacent time scale intervals are calculated respectively according to the time scale information, and finally whether the received data frame is complete is judged according to the average time scale interval and the adjacent time scale interval, and corresponding operations are performed. The method uses the time scale information of the data frame to obtain the interval between adjacent time scales to judge the integrity of the data frame, avoiding the problem of low credibility caused by using the data content to verify the integrity in the prior art, and at the same time The method can also be applied to more scenarios, expanding the application range of detecting data integrity.
