The reliability, stability and scalability of software operation have always been important indicators for testing the performance of information systems. There is no unified interface protocol and standard for drone control information systems in China, which leads to the current situation of diverse interface forms and inconsistent communication protocols for detection, disposal and monitoring equipment for drone control. When the same drone control information system works in different modes and environments, it needs to access a variety of equipment data and distribute control data. When switching interface protocols, it is easy to cause problems such as machine crashes and software operation abnormalities that affect the normal operation of the information system, thereby affecting the business efficiency of drone control and reducing the software usage experience.

[0080] Example 2

[0081] like Figure 2As shown, this embodiment provides an interface dynamic adaptation device in a non-down state, including: an interface file configuration unit, an interface file dynamic cache unit and an interface dynamic adaptation unit.

[0082] The interface file configuration unit is used to obtain the interface configuration file, define the interface attributes, and store the defined interface configuration file;

[0083] The interface file dynamic cache unit is used to convert the interface configuration file, change the interface class of the converted interface configuration file, reload the changed interface class, and update the class file in real time;

[0084] The interface dynamic adaptation unit is used to obtain the communication protocol, data frame length and data identification number of the input data, and judge and verify the interface file in combination with the interface class library, identify the corresponding interface configuration file, parse the interface configuration file through data structure comparison and parsing technology, and distribute the parsed data.

[0085] In some possible embodiments, Figure 3 As shown, the purpose of the interface file configuration unit is to provide a way to manually define and maintain the interface configuration file, and define different field attributes, receiving and sending modes, and communication methods for different interface data. The interface file configuration is presented in the form of a visual human-computer interaction interface, and system maintenance personnel can quickly and easily configure the interface file. The interface file definition content includes: data source name, field name, field length, communication method, big-endian and small-endian formats, version number, verification method, frame identification, etc. The defined interface configuration file is binary serialized in XML or JSON format and stored in the system database or file system. Administrators can also modify, delete, and other operations on the completed interface configuration files.

[0086] like Figure 4As shown, the interface file dynamic cache unit is to maintain the latest and real-time performance of the interface file during system runtime, ensuring that the system can correctly perform interface data adaptation. The interface file dynamic cache operation is performed by setting a timing thread or receiving a driving signal from the interface file configuration module. By continuously acquiring the interface configuration file of the storage unit, the serialized binary byte stream is converted into a binary character stream, and the character stream is converted into a JAVA entity class using JAVA reflection technology. The name, version number, communication method and other contents of the interface configuration file are hashed to generate a 128-bit unique identifier as the JAVA entity class name of the interface file. The Class running file in the virtual machine is reloaded through the JAVA runtime class reloading technology, and expired Class files are removed. According to the communication method of the interface file, the current communication mode of the system is dynamically adjusted, and data communication methods and channels such as the network, serial port, and USB are turned on or off to ensure the smoothness of data transmission and reception. By dynamically caching the interface file, the interface adaptation file in the memory of the virtual machine at runtime is updated, thereby ensuring that the interface configuration file is updated and the communication method is adapted without the system crashing, and the correctness of interface data transmission and reception and adaptation at runtime is ensured.

[0087] like Figure 5 As shown, the interface dynamic adaptation unit is to complete the interface type judgment and data parsing of the external input data, and can automatically perceive the interface type change during the dynamic change of the interface, and parse the data content into the internal data format. The interface dynamic adaptation unit identifies the corresponding interface configuration file by judging and verifying the communication protocol, data frame length, data identification number and other information of the input data, and outputs the parsed data according to the output format of the control file through data structure comparison and parsing technology. The control interface file clearly stipulates the input data structure composition, the corresponding output structure composition of the analysis, the data distribution address after parsing and the data distribution communication method in the parsing process. The interface dynamic configuration unit realizes fast interface matching and data parsing of the input data by constructing a fast parsing model, and distributes the parsed data to the corresponding unit according to the data distribution method.

[0088] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
