Technical Field

Background
A distributed system is a software system built on a network and typically includes a plurality of modules that communicate with one another over the network using a communication protocol.

Such a method has the following disadvantages: (1) easily omit: when the communication protocol changes, the communication protocol is not easily distinguished by eyes, for example: a certain communication protocol comprises multi-level data structure nesting, and when the data structure of a nesting layer changes, a maintainer easily omits the change; (2) the efficiency is low: when there are a large number of modules in a distributed system, it is very inefficient to update the communication protocol version manually.

In order to provide a thorough understanding of the present invention, detailed steps and detailed structures will be set forth in the following description in order to explain the present invention. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.
As described above, the current distributed system updates the communication protocol version manually, which is not only easy to miss the change of the communication protocol, but also inefficient. Based on this, the present invention provides a scheme for updating a communication protocol version number of a distributed system, and the following describes a scheme for updating a communication protocol version number of a distributed system according to an embodiment of the present invention with reference to the drawings.
Fig. 1 shows a schematic flow diagram of a method 100 for updating a communication protocol version number for a distributed system according to an embodiment of the invention. As shown in fig. 1, a method 100 for updating a communication protocol version number in a distributed system may include the steps of:
in step S110, respective syntax structure representations of the code version before modification and the code version after modification are generated, defined as a first syntax structure representation and a second syntax structure representation, respectively.
In an embodiment of the present invention, the method shown in fig. 1 may be used for a distributed system including a plurality of modules to automatically update a preset communication protocol version employed for communication between the modules. In general, the communication protocol may change when the code version is modified. Thus, it is possible to determine whether a change has occurred in the communication protocol by comparing the respective communication protocol data structures in the pre-modified code version and the modified code version. However, if the source code is directly analyzed to obtain the communication protocol data structure, the calculation amount is too large, and the accuracy is not high.
Based on this, in the embodiment of the present invention, in step S110, respective syntax structure representations, for example, abstract syntax structure representations, may be generated for the code version before modification and the code version after modification, respectively, so as to quickly acquire the communication protocol data structure in the code by analyzing the generated syntax structure representations. To distinguish from each other, the syntax structure representation generated for the code version before modification may be defined as a first syntax structure representation and the syntax structure representation generated for the code version after modification may be defined as a second syntax structure representation. Here, the first syntax structure representation and the second syntax structure representation are defined only for distinguishing each other, and have no other limitation.
Illustratively, the generating of the syntax structure representation of each of the pre-modified code version and the modified code version in step S110 may further include: an Abstract Syntax Tree (AST) is generated for each of the code version before modification and the code version after modification. That is, the syntax structure representations generated separately for the pre-modified and post-modified code versions may be abstract syntax trees. Wherein the abstract syntax tree generated for the code version before modification may be defined as a first abstract syntax tree and the abstract syntax tree generated for the code version before modification may be defined as a second abstract syntax tree. Here, the first abstract syntax tree and the second abstract syntax tree are defined only to distinguish each other, and there is no other limitation.
In computer science, an abstract syntax tree (or syntax tree for short) is an abstract representation of the syntax structure of a source code. It represents the syntactic structure of the programming language in the form of a tree, each node on the tree representing a structure in the source code. The communication protocol data structures of the code versions before and after modification are obtained based on the abstract syntax trees of the code versions before and after modification, so that the efficiency and the reliability are high.
In one example, a CastXML tool may be used to generate abstract syntax tree files for each of the code versions before and after modification. The CastXML tool can generate the structural organization relation of the input codes according to the grammar of C/C + +, and describe a grammar tree in an XML file format. In other examples, any other suitable method or tool may be employed to generate the abstract syntax tree file for each of the code versions before and after modification.
With continued reference to fig. 1, the subsequent steps of a method 100 for updating a communication protocol version number for a distributed system according to an embodiment of the present invention are described.
In step S120, the communication protocol data structures in the first syntax structure representation and the second syntax structure representation are obtained, and are defined as a first communication data structure and a second communication data structure, respectively.
Based on their respective syntax structure representations (e.g., abstract syntax trees) generated at step S110 for the code versions before and after modification, the respective communication protocol data structures in the code versions before and after modification can be obtained by parsing the generated abstract syntax tree file. In the embodiment of the present invention, in order to facilitate fast obtaining of the respective communication protocol data structures from the abstract syntax trees of the code versions before and after modification, a preset structure body conforming to a preset naming specification may be defined (for example, a macro is defined, and a prefix of the macro may be communication _ api), and the respective communication protocol data structures in the code versions before and after modification are all generated based on the preset structure body. In this way, the communication protocol data structure may be identified in advance, making it more efficient to find the communication protocol data type from the abstract syntax number.
Based on this, the obtaining of the respective communication protocol data structures in the first syntax structure representation and the second syntax structure representation in step S120 may further include: analyzing the first syntactic structure representation and the second syntactic structure representation to search a data structure conforming to the preset naming specification; and acquiring the data type of the first member of the data structure which accords with the preset naming specification so as to obtain the communication protocol data structure. Specifically, the syntax structure representation files (for example, abstract syntax tree files) respectively generated for the code versions before and after modification in step S110 may be traversed, and a data structure conforming to the preset naming specification, for example, a structure with a prefix of communication _ api, may be searched from the syntax structure representation files, and then the data types of the first members of the structure may be acquired, that is, the communication protocol data structure in the syntax structure representation file may be obtained.
To distinguish from each other, a communication protocol data type acquired from the syntax structure representation corresponding to the code version before modification may be defined as a first communication protocol data structure (may be simply referred to as a first communication data structure), and a communication protocol data type acquired from the syntax structure representation corresponding to the code version after modification may be defined as a second communication protocol data structure (may be simply referred to as a second communication data structure). Here, the first communication data structure and the second communication data structure are defined only to distinguish each other, and there is no other limitation.
In step S130, a first text message is generated based on all the syntax information of the first communication data structure, and a second text message is generated based on all the syntax information of the second communication data structure.
Based on the respective communication protocol data structures in the code versions before and after modification acquired at step S120, unique identifiers of the respective communication protocol data structures in the code versions before and after modification may be generated for determining whether the communication protocol data structures before and after modification have changed based on the unique identifiers. In an embodiment of the present invention, a text message of a communication protocol data structure may be generated based on all syntax information of the communication protocol data structure, and a unique identification of the communication protocol data structure may be generated based on the text message.
Illustratively, the text message may be a character string generated based on all the syntax information of the communication protocol data structure, e.g., all the syntax information of the communication protocol data structure may be combined into a character string. Illustratively, all syntax information of the communication protocol data structure may include self information and sub-member information of the communication data structure. The self information may include domain name information (i.e., namespace name), data structure type (e.g., struct/union) information, and occupancy size information. The child member information may include child member name information, basic data type (e.g., int/char/float/long) information, development information of structure/enumeration/association/definition type (typedef), and occupancy size information.
For distinction, text information generated based on all syntax information of the communication protocol data type in the code version before modification may be defined as the first text information, and text information generated based on all syntax information of the communication protocol data type in the code version after modification may be defined as the second text information. Here, the first text information and the second text information are defined only to distinguish each other, and there is no other limitation.
In step S140, unique identifiers of the first text message and the second text message are calculated, and are respectively defined as a first unique identifier and a second unique identifier.
As previously described, in embodiments of the present invention, a text message of a communication protocol data structure may be generated based on all syntax information of the communication protocol data structure, and a unique identification of the communication protocol data structure may be generated based on the text message. Illustratively, the unique identifier may be a message digest value (e.g., an MD5 value) of the text message. That is, the message digest value of the first text message may be calculated as a unique identification of the communication protocol data type in the pre-modified code version, and the message digest value of the second text message may be calculated as a unique identification of the communication protocol data type in the modified code version.
For the purpose of distinction, the unique identification of the first text information may be defined as a first unique mark, and the unique identification of the second text information may be defined as a second unique mark. Here, the first unique identifier and the second unique identifier are defined only for distinguishing each other, and there is no other limitation.
In step S150, the first unique identifier and the second unique identifier are compared, and the version number of the preset communication protocol is updated when the first unique identifier and the second unique identifier are different.
Based on the unique identifications of the respective communication protocol data structures in the code versions before and after modification calculated in step S140, it is possible to determine whether the communication protocol before and after modification has changed by determining whether the unique identifications of the respective communication protocol data structures in the code versions before and after modification are the same. If the uniqueness identifications of the respective communication protocol data structures in the code versions before and after modification are the same, indicating that the communication protocols before and after modification are not changed; if the unique identifiers of the respective communication protocol data structures in the code versions before and after modification are different, which indicates that the communication protocols before and after modification are changed, the version number of the communication protocol (such as the preset communication protocol used for communication between the modules of the distributed system) corresponding to the compared communication protocol data structure may be updated, for example, the version number of the communication protocol may be incremented by 1. Thus, the method for updating the version number of the communication protocol in the distributed system according to the embodiment of the invention is realized.
In an embodiment of the present invention, the method for updating the communication protocol version number in the distributed system may be implemented based on a hook script of distributed version control software (GIT). Specifically, the developer submits the code using GIT commit, the GIT client automatically triggers GIT post-commit script, in the post-commit script, the above steps S110 to S150 may be implemented, and when the unique identifiers of the respective communication protocol data structures in the code versions before and after submission are different, the version number of the corresponding communication protocol may be updated, and the code versions are additionally submitted using GIT commit-amend.
Based on the above description, the method for updating the version number of the communication protocol in the distributed system according to the embodiment of the present invention generates the syntax structure representation for the code version before and after modification, obtains the communication protocol data structure from the generated syntax structure representation, and determines whether the communication protocol changes by comparing the unique identifier of the communication protocol data structure, if so, the version number of the communication protocol is automatically updated, thereby greatly improving the reliability of the distributed system for finding the change of the communication protocol and the efficiency of updating the version number of the communication protocol, and effectively solving the problems of easy omission and low efficiency in a manual mode.
Fig. 2 shows a more detailed flowchart of a method for updating a communication protocol version number of a distributed system according to an embodiment of the present invention. As shown in fig. 2, a method for updating a version number of a communication protocol in a distributed system according to an embodiment of the present invention may include the following steps:
first, in step S1, using the GIT commit submitting code, a commit node a (i.e., a code version) is generated and the GIT client automatically triggers the GIT post-commit hook script.
In which GIT is a distributed version control software, originally authored by linus torvalds, released in GPL in 2005. The GIT can support various hook scripts and is triggered by partial GIT commands to complete user-defined automatic operation.
The 5 steps after the step S1 are equally divided into two branches, namely, the left branch is executed for the code version corresponding to the commit node a, and the right branch is executed for the code version before the commit node a. To distinguish between the two, the left branch of these 5 steps is labeled S2A through S6A, and the right branch is labeled S2B through S6B. It should be understood that the execution order of the left and right branches of each of the 5 steps may not be sequential.
In step S2A, a C/C + + abstract syntax tree of the code version corresponding to the commit node a is generated. At step S2B, a C/C + + abstract syntax tree of the code version before commit node a is generated.
In computer science, an Abstract Syntax Tree (AST), or simply Syntax Tree (Syntax Tree), is an Abstract representation of the Syntax structure of source code. It represents the syntactic structure of the programming language in the form of a tree, each node on the tree representing a structure in the source code. A common implementation tool is CastXML, which can generate the structural organization relation of input codes according to the grammar of C/C + +, and describe a grammar tree in an XML file format. After the syntax tree file is generated using the CastXML tool, the file may be parsed to obtain a fully expanded string of the communication protocol data structure, which is used to calculate the MD5 value, indicating that the communication protocol version number needs to be updated when the MD5 value changes, as will be described below.
At step S3A, the syntax tree is parsed for all data structures beginning with communication _ api. At step S3B, the syntax tree is parsed for all data structures beginning with communication _ api.
In step S4A, the data type of the first member of these data structures is obtained, i.e., all communication protocol data structures are obtained. In step S4B, the data type of the first member of these data structures is obtained, i.e., all communication protocol data structures are obtained.
And in the post-commit script, generating abstract syntax trees before and after submission, and finding out a communication protocol data structure according to the predefined identification of the communication protocol data structure. Wherein the communication protocol data structure may be identified by: first, a macro is defined that declares a communication protocol: # define COMM _ API _ EXPORT (type) structcomunication _ API # # type { type a; }; the COMM _ API _ execute declaration is then used at the definition of the communication protocol data structure. Based on this, an abstract syntax tree can be generated by using CastXML (or other tools), the structure body in the syntax tree is filtered, and when the name conforms to the beginning of communication _ api, the first member type is obtained, namely, the communication protocol data structure.
In step S5A, the syntax tree is parsed, and the complete data structure of the data protocol is expanded to generate a character string. In step S5B, the syntax tree is parsed, and the complete data structure of the data protocol is expanded to generate a character string.
In step S6A, digest information of the character string is calculated. In step S6B, digest information of the character string is calculated.
In the abstract syntax tree, all information of the communication data structure, including domain name information, basic data type, user-defined type expansion, type data length information, etc., are searched and combined into a character string, and the MD5 value of the character string is calculated as the unique identifier of the communication data structure. MD5(Message-Digest Algorithm) is a widely used cryptographic hash function that generates a 128-bit (16-byte) hash value (hash value) that represents data Digest information.
In step S7, the MD5 values of all communication data structures before and after commit are compared, and if there is a change, the version number of the corresponding communication data structure is updated in step S8 (i.e., the version number of the communication protocol in which MD5 has changed is incremented by 1), and the updated version number is additionally committed to commit a in step S9 with git commit — amend. In step S10, the post-commit hook script ends. For the communication data structure with unchanged MD5 value, the version number of the corresponding communication protocol does not need to be updated, and the flow directly proceeds to step S10.
More specific operations of the method for updating the version number of the communication protocol by the distributed system according to the embodiment of the present invention are described above with reference to fig. 2. Based on the above description, the method for updating the version number of the communication protocol in the distributed system according to the embodiment of the present invention has an automatic identification method of the data structure of the communication protocol: that is, based on the macro declaration and the abstract syntax tree, the data structures describing the communication protocol may be automatically identified using scripts. In addition, the method for updating the version number of the communication protocol in the distributed system according to the embodiment of the invention can identify the change of the data structure: that is, based on the abstract syntax tree, all syntax information (including data structure member names, type expansion, memory occupation size, and the like) of a certain data structure is obtained, a character string is generated, and the summary information MD5 is calculated, which indicates that the data structure is changed if MD5 is changed.
Generally, the method for updating the version number of the communication protocol in the distributed system according to the embodiment of the invention can realize the function of automatically updating and submitting the version number of the communication protocol through the post-commit and pre-push hook scripts of the GIT, only a macro statement is used as the communication protocol at the definition position of the communication data structure, and the subsequent updating of all the version numbers is completed by the hook scripts of the GIT. The method for automatically updating the communication protocol version based on the GIT can avoid the problems of low labor cost, low efficiency and high error probability caused by manual maintenance, and can be applied to the field of communication protocol consistency guarantee of an interprocess communication system. An interprocess communication system refers to a communication system between software running on a computer (or embedded device). The interprocess communication protocol refers to a communication information structure negotiated among different processes and definition thereof, and communication links can be various: such as network port, USB, serial port, etc. The interprocess communication system comprises a plurality of different program installation packages, and the communication protocol among the programs needs to keep consistency, thereby ensuring that the communication content can be correctly transmitted and responded. Therefore, the method for updating the version number of the communication protocol by the distributed system according to the embodiment of the invention can be applied to the application (such as a robot system) which needs a large amount of interprocess communication, greatly improve the maintenance efficiency of the communication protocol and ensure the correctness of the communication.
The method for updating the version number of the communication protocol in the distributed system according to the embodiment of the invention is exemplarily described above. For example, the method for updating the version number of the communication protocol in the distributed system according to the embodiment of the present invention may be implemented in the distributed system, or may be implemented in any device, apparatus, or system having a memory and a processor. In addition, the method for updating the version number of the communication protocol in the distributed system according to the embodiment of the invention can also be implemented in any interprocess communication system.
According to another aspect of the present invention, there is provided a computing device including a plurality of modules, the modules communicating with each other through a preset communication protocol, the computing device updating the version number of the preset communication protocol by using the method for updating the version number of the communication protocol in the distributed system described above with reference to fig. 1 and 2.

According to still another aspect of the present invention, there is provided an autopilot system including a plurality of modules communicating with each other through a preset communication protocol, the autopilot system updating the version number of the preset communication protocol by using the method of updating the version number of the communication protocol in a distributed system described above with reference to fig. 1 and 2. An example autopilot system employing a method for updating a communication protocol version number for a distributed system in accordance with an embodiment of the present invention is described below in conjunction with fig. 4. Fig. 4 shows a schematic block diagram of an example autopilot system 400 that employs a method of updating a communication protocol version number for a distributed system in accordance with an embodiment of the present invention.
As shown in fig. 4, the autopilot system 400 includes a vehicle position identification module 410, a vehicle state identification module 420, an external environment identification module 430, a travel plan generation module 440, and a vehicle control module 450. Wherein the vehicle location identification module 410 is configured to identify a location of the vehicle on the map. The vehicle state identification module 420 is configured to identify a vehicle state of the vehicle. The external environment identification module 430 is configured to identify an external environment of the vehicle. The travel plan generation module 440 is configured to generate a travel plan including a control target value of the automatic driving control of the vehicle based on the vehicle position identified by the vehicle position identification module 410, the vehicle state identified by the vehicle state identification module 420, and the external environment identified by the external environment identification module 430. The vehicle control module 450 is configured to send an instruction to a brake of the vehicle based on the control target value of the travel plan generated by the travel plan generation module 440, thereby executing the automated driving control.
As shown in fig. 4, the autopilot system 400 includes a plurality of modules, respectively, a vehicle position identification module 410, a vehicle state identification module 420, an external environment identification module 430, a travel plan generation module 440, and a vehicle control module 450. The vehicle position identification module 410, the vehicle state identification module 420 and the external environment identification module 430 all need to communicate with the driving plan generation module 440 (i.e. transmit their identification results to the driving plan generation module 440), the driving plan generation module 440 needs to communicate with the vehicle control module 450 (i.e. transmit its generated driving plan to the vehicle control module 450), therefore, all these communications between these modules need to adopt a certain communication protocol, and the communication protocols between these modules must be consistent to ensure the correct implementation of the communications. Based on this, the autopilot system 400 can detect whether the communication protocol between its modules has changed (has remained consistent) by updating the version number of the communication protocol according to the distributed system described above with reference to fig. 1 and 2, and if so, automatically update to correctly maintain communication, thereby ensuring reliable and safe autopilot.
The following describes in detail a process in which the autopilot system 400 detects the consistency of the communication protocols among the modules of the vehicle position identification module 410, the vehicle state identification module 420, the external environment identification module 430, the travel plan generation module 440, and the vehicle control module 450 by using the method of updating the communication protocol version numbers according to the distributed system described above with reference to fig. 1 and 2, and updates the communication protocol version numbers when a change in the communication protocols is detected.
First, as described above, the vehicle position identification module 410, the vehicle state identification module 420, and the external environment identification module 430 each need to communicate with the travel plan generation module 440 (i.e., transfer their identification results to the travel plan generation module 440), the travel plan generation module 440 needs to communicate with the vehicle control module 450 (i.e., transfer its generated travel plan to the vehicle control module 450), and the vehicle position identification module 410, the vehicle state identification module 420, the external environment identification module 430, and the vehicle control module 450 may communicate with the travel plan generation module 440 using the same communication protocol, respectively. Therefore, it is necessary to determine whether or not the communication protocol data structures in the codes implementing the vehicle position identification module 410, the vehicle state identification module 420, the external environment identification module 430, the travel plan generation module 440, and the vehicle control module 450 are changed in the modification of their respective code versions.
For distinction, a code implementing the vehicle position recognition module 410 is defined as a vehicle position recognition code, a code implementing the vehicle state recognition module 420 is defined as a vehicle state recognition code, a code implementing the external environment recognition module 430 is defined as an external environment recognition code, a code implementing the travel plan generation module 440 is defined as a travel plan generation code, and a code implementing the vehicle control module 450 is defined as a vehicle control code. In these codes, the same structure body conforming to the preset naming specification is used to define the communication protocol data structure (for example, the aforementioned data structure beginning with communication _ api). Based on this, it is possible to detect whether a change occurs in the communication protocol data structure thereof after implementing the modification of the code version of each of the aforementioned five modules.
For example, for a code version of the vehicle state identification code, the respective syntax structure representations (e.g., abstract syntax trees) of the code version and a code version before the code version may be generated based on the hook script of the distributed version control software, which are respectively defined as a first syntax structure representation and a second syntax structure representation; then, acquiring respective communication protocol data structures in the first syntax structure representation and the second syntax structure representation (for example, analyzing the first syntax structure representation and the second syntax structure representation to search for a data structure conforming to the preset naming specification, and then acquiring a data type of a first member of the data structure conforming to the preset naming specification to obtain the communication protocol data structure), which are respectively defined as a first communication data structure and a second communication data structure; then generating a first text message based on all the syntax information of the first communication data structure and a second text message based on all the syntax information of the second communication data structure (e.g., combining all the syntax information of the first communication data structure into a first string and combining all the syntax information of the second communication data structure into a second string); then calculating respective unique identifications of the first text message and the second text message (for example, calculating respective MD5 values of the first text message and the second text message), which are respectively defined as a first unique identification and a second unique identification; finally, the first unique identifier and the second unique identifier are compared, and the version number of the first communication protocol is updated when the first unique identifier and the second unique identifier are different. That is, for a code version of the vehicle state identification code, if the MD5 values of the character strings combined by all the information of the respective communication protocol data structures of the code version are not equal compared with the code version before the code version, it indicates that the communication protocol data structure is changed compared with the code version before the code version, and the communication protocol version number corresponding to the communication protocol data structure should be modified (e.g., the version number is incremented by 1). If the MD5 value of the string combined by all the information of their respective communication protocol data structures is equal when the code version is compared with the code version before the code version, it indicates that the communication protocol data structure is unchanged when the code version is compared with the code version before the code version, and the communication protocol version number corresponding to the communication protocol data structure does not need to be modified.
Similarly, for the vehicle state identification code, the external environment identification code, the travel plan generation code, and the vehicle control code, it is possible to adopt the method described above to detect whether a change has occurred in the communication protocol data structure therein, and to automatically update the communication protocol version number when the change has occurred.
The automatic driving system and the automatic updating method of the communication protocol version number between the modules thereof according to the embodiment of the present invention are exemplarily described above, and it should be understood that the automatic driving system shown in fig. 4 is merely exemplary, the automatic driving system may further include any other required modules not shown, and the communication protocol between the modules may also be updated by the method of updating the communication protocol version number by using the distributed system according to the embodiment of the present invention.
According to still another aspect of the present invention, there is also provided a vehicle, where the vehicle may include the above-mentioned autopilot system, and the autopilot system of the vehicle may update the communication protocol used for communication between the modules thereof according to the method for updating the version number of the communication protocol by the distributed system according to the embodiment of the present invention, and a person skilled in the art may understand the method for updating the communication protocol by combining the foregoing description, and details are not described here for brevity.
According to yet another aspect of the present invention, there is also provided a drone, which may include a flight control system including a plurality of modules communicating with each other through a preset communication protocol, the drone updating the version number of the preset communication protocol using the method of updating the version number of the communication protocol of the distributed system described above with reference to fig. 1 and 2. An example drone employing a method of updating a communication protocol version number for a distributed system according to an embodiment of the invention is described below in conjunction with fig. 5. Fig. 5 shows a schematic block diagram of an exemplary drone 500 that employs a method of updating a communication protocol version number for a distributed system according to an embodiment of the present invention.
As shown in fig. 5, the drone 500 includes a flight control system including an instruction signal receiving module 510, a sensor data processing module 520, and a control amount calculating module 530. The command signal receiving module 510 is configured to receive a command from a remote controller (not shown) of the drone 500 and a sensor signal from a sensor, transmit the received sensor signal to the sensor data processing module 520, and transmit the received command from the remote controller to the control amount calculating module 530. The sensor data processing module 520 is configured to process and calculate the sensor signal to obtain position and orientation information of the drone 500, and transmit the position and orientation information obtained by processing to the control quantity calculating module 530. The control amount calculation module 530 is configured to calculate a control amount of a corresponding controller based on an instruction of the remote controller and the position and orientation information, and output the control amount to a driving mechanism.
As described above, the drone 500 includes a flight control system including a plurality of modules, respectively, a command signal receiving module 510, a sensor data processing module 520, and a control amount calculating module 530. The command signal receiving module 510, the sensor data processing module 520, and the control amount calculating module 530 all need to communicate with each other. Therefore, a certain communication protocol is required for the communication between the modules, and the communication protocol between the modules must be consistent to ensure the correct implementation of the communication. Based on this, the drone 500 may adopt the method of updating the version number of the communication protocol according to the distributed system described above with reference to fig. 1 and fig. 2 to detect whether the communication protocol between the modules of its flight control system changes (keeps consistent), and if so, automatically update to correctly keep communication, thereby realizing correct and safe operation of the drone.
The following describes in detail a process in which the drone 500 detects consistency of the communication protocol among the modules of the instruction signal receiving module 510, the sensor data processing module 520, and the control amount calculating module 530 by using the method of updating the communication protocol version number according to the distributed system described above with reference to fig. 1 and 2, and updates the communication protocol version number when detecting a change in the communication protocol.
First, as described above, the command signal receiving module 510, the sensor data processing module 520, and the control amount calculating module 530 all need to communicate with each other. Therefore, it is necessary to determine whether or not the communication protocol data structure in the code implementing the instruction signal receiving module 510, the sensor data processing module 520, and the control amount calculating module 530 is changed in the modification of the respective code versions thereof.
For distinction, a code implementing the instruction signal receiving module 510 is defined as an instruction signal receiving code, a code implementing the sensor data processing module 520 is defined as a sensor data processing code, and a code implementing the control amount calculating module 530 is defined as a control amount calculating code. In these codes, the same structure body conforming to the preset naming specification is used to define the communication protocol data structure (for example, the aforementioned data structure beginning with communication _ api). Based on this, it can be detected whether the communication protocol data structure changes after the modification of the code version of each of the aforementioned three modules is implemented.
For example, for a code version of the instruction signal receiving code, the respective syntax structure representations (e.g. abstract syntax trees) of the code version and the code version before the code version can be generated based on the hook script of the distributed version control software, which are respectively defined as a first syntax structure representation and a second syntax structure representation; then, acquiring respective communication protocol data structures in the first syntax structure representation and the second syntax structure representation (for example, analyzing the first syntax structure representation and the second syntax structure representation to search for a data structure conforming to the preset naming specification, and then acquiring a data type of a first member of the data structure conforming to the preset naming specification to obtain the communication protocol data structure), which are respectively defined as a first communication data structure and a second communication data structure; then generating a first text message based on all the syntax information of the first communication data structure and a second text message based on all the syntax information of the second communication data structure (e.g., combining all the syntax information of the first communication data structure into a first string and combining all the syntax information of the second communication data structure into a second string); then calculating respective unique identifications of the first text message and the second text message (for example, calculating respective MD5 values of the first text message and the second text message), which are respectively defined as a first unique identification and a second unique identification; finally, the first unique identifier and the second unique identifier are compared, and the version number of the first communication protocol is updated when the first unique identifier and the second unique identifier are different. That is, for a code version of the instruction signal receiving code, if the MD5 values of the character strings combined by all the information of the respective communication protocol data structures of the code version are not equal compared with the code version before the code version, it indicates that the communication protocol data structure is changed compared with the code version before the code version, and the communication protocol version number corresponding to the communication protocol data structure should be modified (for example, the version number is incremented by 1). If the MD5 value of the string combined by all the information of their respective communication protocol data structures is equal when the code version is compared with the code version before the code version, it indicates that the communication protocol data structure is unchanged when the code version is compared with the code version before the code version, and the communication protocol version number corresponding to the communication protocol data structure does not need to be modified.
Similarly, for both the sensor data processing code and the control amount calculation code, the above-described method may be employed to detect whether a change has occurred in the communication protocol data structure therein, and the above-described method may be employed to automatically update the communication protocol version number when the change has occurred.
The above describes the automatic updating method of the communication protocol version number between modules of the unmanned aerial vehicle and the flight control system thereof according to the embodiment of the present invention by way of example, it should be understood that the unmanned aerial vehicle and the flight control system thereof shown in fig. 5 are only exemplary, the unmanned aerial vehicle and the flight control system thereof may further include any other required modules that are not shown, and the communication protocol between these modules may also be updated by adopting the method of updating the communication protocol version number by using the distributed system according to the embodiment of the present invention.
The application scenario of the method for updating the version number of the communication protocol in the distributed system according to the embodiment of the invention is exemplarily described above. Based on the above description, the method for updating the version number of the communication protocol by the distributed system and the device or system using the method generate the syntax structure representation for the code versions before and after modification, acquire the communication protocol data structure from the generated syntax structure representation, determine whether the communication protocol changes by comparing the unique identifier of the communication protocol data structure, and automatically update the version number of the communication protocol if the communication protocol changes, thereby greatly improving the reliability of the distributed system for finding the change of the communication protocol and the efficiency for updating the version number of the communication protocol, and effectively solving the problems of easy omission and low efficiency in a manual mode.
