In the related art, a development engineer develops a corresponding protocol description text for a terminal device according to a communication protocol provided by a device manufacturer of the terminal device. Development engineers need to rely on expertise in communication protocols to find protocol elements that can be used to construct protocol description text one by one, which is inefficient.
In order to improve the construction efficiency of the protocol description text, the protocol description text of other terminal equipment similar to the equipment model of the current terminal equipment can be searched, and the protocol description text of the other terminal equipment is modified on the basis of the protocol description text of the other terminal equipment. However, when the number of protocol description texts is large, the number of similar device models is also large, other terminal devices corresponding to the similar device models are also large, and the similarity of the device models and the similarity of the communication protocols have a certain relationship but not a certain relationship, so that a less suitable protocol description text is possibly selected as a basis for protocol modification, and the efficiency improvement effect is limited.
Therefore, how to quickly and accurately select similar protocol description texts from a large number of protocol description texts is a key breakthrough point for shortening the construction period of the protocol description texts.
In order to solve the above problems, the present application provides a method, an apparatus, a device, and a storage medium for constructing a protocol description text. In the application, considering that the communication protocol of the terminal equipment mainly consists of a transmission frame and a data response frame and the communication protocol has certain integrity, if the transmission frame similarity of the two equipment is higher, the data response frame similarity is higher, the analysis rule similarity of the data response frame is higher, at least one transmission frame in the first protocol description text is taken as a text feature, and the reference protocol description text of the first protocol description text is determined in the second protocol description text, which is equivalent to the protocol description text similar to the first protocol description text; based on the reference protocol description text, the remaining content in the first protocol description text excluding the at least one transmission frame is determined. Therefore, the efficiency and the accuracy of searching similar protocol description texts in a large number of protocol description texts are improved, and the construction efficiency of the protocol description texts is further improved.

In this embodiment, at least one transmission frame in the first protocol description text may be pre-constructed by a professional based on a communication protocol provided by a device manufacturer of the first device, for example, 10 transmission frames need to be constructed in total in the first protocol description text, and 1 transmission frame is pre-constructed by the professional. Compared with the construction of the whole first protocol description text, the construction of one or a plurality of transmission frames in the first protocol description text greatly reduces the time consumption of professionals. After the professional constructs at least one transmission frame in the first protocol description text, the transmission frame may be stored in a database, and the transmission frame may be input into the protocol description text constructing apparatus, so in this embodiment, the at least one transmission frame in the first protocol description text may be acquired from the database or the at least one transmission frame input by the user may be received.
S402, taking at least one transmission frame as a text characteristic of a first protocol description text, determining a reference protocol description text of the first protocol description text in a second protocol description text, wherein the second protocol description text is a constructed protocol description text of a second device, and the second device and the first device are different devices.

In this embodiment, the second protocol description text may be obtained from the protocol database. And taking at least one transmission frame in the first protocol description text as the text characteristic of the first protocol description text, and matching the at least one transmission frame with the transmission frame in the second protocol description text. Considering that the communication protocol of the terminal equipment mainly consists of a transmission frame and a data response frame, and the communication protocol has certain integrity, if the transmission frame similarity of the two equipment is higher, the data response frame similarity is also higher, and the analysis rule similarity of the data response frame is also higher, so that a protocol description text similar to the first protocol description text can be selected from the second protocol description text based on the matching result of the transmission frame in the first protocol description text and the transmission frame in the second protocol description text. Considering that this protocol description text is used as a reference object for constructing the first protocol description text, the protocol description text is referred to as a reference protocol description text for convenience of distinction.
As an example, the first device is a device a, the second device includes a device B, a device D, and a device C, the protocol description text of the device B, the protocol description text of the device D, and the protocol description text of the device C are already constructed, the protocol description text of the device a needs to be constructed, at least one transmission frame in the protocol description text of the device a may be constructed by a professional, and then the at least one transmission frame is used as a text feature, and a reference protocol description text similar to the protocol description text of the device a is searched in the protocol description text of the device B, the protocol description text of the device D, and the protocol description text of the device C, so as to further construct and complete the protocol description text of the device a based on the reference protocol description text.
S403, determining the rest content except at least one transmission frame in the first protocol description text according to the reference protocol description text.
In the present embodiment, in determining the reference protocol description text, the protocol content may be extracted in the reference protocol description text. Such as extracting the transmitted frames, data parsing rules, software versions, etc. The remaining content in the first protocol description text may be generated based on the extracted protocol content.
According to the method and the device for searching the reference protocol description text, based on at least one transmission frame in the first protocol description text, the reference protocol description text similar to the first protocol description text is searched in the constructed second protocol description text, and therefore the searching efficiency and accuracy of the similar protocol description text are improved. The remaining content of the first protocol description text is determined based on the reference protocol description text, a complete first protocol description text is obtained, and then the first protocol description text can be modified and corrected by a professional. Because the reference protocol description text is higher in similarity with the first protocol description text, the accuracy of generating the first protocol description text based on the reference protocol description text is higher, and the workload of modifying and correcting the first protocol description text by professionals after the first protocol description text is generated is greatly reduced, so that the construction efficiency of the protocol description text is effectively improved.
In some embodiments, at least one transmission frame in the first protocol description text may be an nth transmission frame in the first protocol description text, n being greater than or equal to 1. Therefore, a professional only needs to develop the nth transmission frame in the first protocol description text, and can determine the rest content in the first protocol description text based on the nth transmission frame and the second protocol description text, so that the construction efficiency of the protocol description text is improved.
Referring to fig. 5, fig. 5 is a second flowchart of a method for constructing a protocol description text according to an embodiment of the present application. As shown in fig. 5, the protocol description text construction method includes:

The first protocol description text may refer to the foregoing embodiments, and will not be described in detail.
In this embodiment, the nth transmission frame in the first protocol description text may be pre-constructed by a professional based on a communication protocol provided by a device manufacturer of the first device. Compared with the construction of the whole first protocol description text, the construction of the nth transmission frame in the first protocol description text consumes less time and does not reduce the construction efficiency of the whole first protocol description text. The nth transmission frame in the first protocol description text may be obtained from the database or may be received as input by the user.
Further, n is 1, and S501 may include: and determining the 1 st transmission frame in the first protocol description text.

Therefore, based on the similarity between the nth transmission frame in the first protocol description text and the nth transmission frame in the second protocol description text, the accuracy and the searching efficiency of the reference protocol description text are improved.
In one possible implementation, S303 includes: performing text matching on an nth transmission frame in the first protocol description text and an nth transmission frame in the second protocol description text, and determining similar transmission frames of the nth transmission frame in the first protocol description text; and determining the reference protocol description text as the protocol description text to which the similar transmission frame belongs.

According to the method and the device for searching the reference protocol description text in the second protocol description text, the reference protocol description text similar to the first protocol description text is searched in the second protocol description text based on the similarity between the nth transmission frame in the first protocol description text and the nth transmission frame in the second protocol description text, and therefore the searching efficiency and the searching accuracy of the similar protocol description text are improved. And determining the rest content of the first protocol description text based on the reference protocol description text to obtain the complete first protocol description text. Because the reference protocol description text is higher in similarity with the first protocol description text, the accuracy of generating the first protocol description text based on the reference protocol description text is higher, and the workload of modifying and correcting the first protocol description text by professionals after the first protocol description text is generated is greatly reduced, so that the construction efficiency of the protocol description text is effectively improved.
By way of example, fig. 6 is a diagram illustrating the construction of protocol description text provided in an embodiment of the present application. As shown in fig. 6, first, a first transmission frame may be developed by a developer based on a protocol text T provided by a device manufacturer of the device D, and input to a protocol matcher; next, all protocol description files (corresponding to the second protocol description file) s= [ S1, S2, … …, sn ] in the protocol library can be loaded through the protocol matcher, wherein S1, S2, … …, sn represent the 1 st, 2 nd, … … th and n th protocol description files respectively, the first transmission frame in the loaded all protocol description files is identified, and a matching data set M (M1, M2, …, mn) is formed by the first transmission frame in the all protocol description files; then, searching a transmission frame most similar to the input first transmission frame in the matched data set M by using a text matching algorithm, and determining a protocol description file where the most similar transmission frame is located; finally, creating the protocol description text of the device D according to the protocol description file of the most similar transmission frame.
Referring to fig. 7, fig. 7 is a flowchart illustrating a method for constructing a protocol description text according to an embodiment of the present application. As shown in fig. 7, the protocol description text construction method provided in this embodiment includes:
s701, determining at least one transmission frame in a first protocol description text, wherein the first protocol description text is the protocol description text of the first device in the construction process.
S702, taking at least one transmission frame as a text characteristic of a first protocol description text, determining a reference protocol description text of the first protocol description text in a second protocol description text, wherein the second protocol description text is a constructed protocol description text of a second device, and the second device and the first device are different devices.
The implementation principles and technical effects of S701 to S702 may refer to the foregoing embodiments, and are not repeated.
S703, extracting protocol elements from the reference protocol description text.
In this embodiment, the protocol element is an element related to a communication protocol and supporting flexible configuration. In the protocol description text, protocol elements related to transmitting frames and/or protocol elements related to signal parsing may be included. Thus, protocol elements related to the transmitted frame and/or protocol elements related to signal parsing may be extracted from the reference protocol description text.
S704, complementing blank elements to be configured in the rest content according to the protocol elements.
In this embodiment, after extracting the protocol element from the reference protocol description text, the protocol element may be added to the blank element to be configured in the remaining content of the first protocol description text, so as to complement the blank element to be configured in the remaining content.
In one possible implementation, at least one transmission frame in the first protocol description text is an nth transmission frame in the first protocol description text, and the blank element includes a blank field. At this time, S703 may include: extracting an allowed configuration field of an mth transmission frame in a reference protocol description text, wherein m is not equal to n; s704 may include: and determining a blank field of an mth transmission frame in the first protocol description text as an allowed configuration field of the mth transmission frame in the reference protocol description text.
In this implementation manner, in the case that at least one transmission frame in the first protocol description text is the nth transmission frame in the first protocol description text, the remaining content in the first protocol description text includes the mth transmission frame, and since the first protocol description text is similar to the reference protocol description text, the mth transmission frame in the first protocol description text is similar to the mth transmission frame in the reference protocol description text, the mth transmission frame in the first protocol description text can be determined with reference to the mth transmission frame in the reference protocol description text. For the construction of the transmission frames, what is configured by the allowed configuration field in the frame structure of the transmission frames is mainly determined, so that the allowed configuration field of the mth transmission frame can be extracted from the reference protocol description text, that is, the protocol element extracted from the reference protocol description text includes the allowed configuration field of the mth transmission frame in the reference protocol description text, and the blank field for determining the mth transmission frame in the first protocol description text is determined as the allowed configuration field of the mth transmission frame in the reference protocol description text.
For example, with reference to the allowed configuration field of the mth transmission frame in the protocol description text having a protocol type field and a protocol address field, the blank field of the mth transmission frame in the first protocol description text may be determined as the protocol type field and the protocol address field, so that the allowed configuration field in the frame structure of the mth transmission frame in the first protocol description text also includes the protocol type field and the protocol address field.
In the case where n is equal to 1, if m is equal to 2, the 2 nd transmission frame in the first protocol description text may be constructed, and if m is equal to 3, the 3 rd transmission frame in the first protocol description text may be constructed, and thus, a plurality of transmission frames in the first protocol description text may be constructed.
In one possible implementation, the protocol elements related to signal parsing include protocol elements related to response frame parsing, S703 may include: extracting protocol elements related to response frame analysis from the reference protocol description file; s704 may include: a protocol element associated with the response frame parsing is added to the first protocol description text. Therefore, the construction of the protocol elements related to the response frame analysis in the first protocol description text is realized, and the construction efficiency of the first protocol description text is improved.
Wherein the protocol element associated with the resolution of the response frame may include a signal point resolution rule of the response frame.
As an example, all the transmission frames extracted from the reference protocol description text can be expressed as:
