Example one
The embodiment provides an airborne intelligent early warning system, which comprises a main control module, and a data receiving module, a resolving analysis module and an early warning and flight parameter display module which are respectively electrically connected with the main control module, as shown in fig. 1.

First, the main control module is a core module for starting the system in this embodiment, and the main control module controls a specific process from initialization to operation of each module of the system, where the work process of the main control module is shown in fig. 2 and includes:
step 1, after a system is started, namely a main control module is started, firstly, system log initialization and database connection initialization are carried out, wherein the log refers to the unified record of the operation condition, abnormal information and the like in the operation process of each module of the system, and the log is possibly written into different threads at the module parts of a plurality of systems at the same time, so that a log access interface needs to be initialized after the system is started in order to balance resource overhead and data synchronization and facilitate fault location and reason analysis after the system is in operation mistakes; similarly, the database connection initialization is also to avoid unnecessary resource overhead, and a connection channel between the system and the database is established when the system is started, so that the system modules including the settlement analysis module and the flight parameter display module read and write data and synchronize the database.
Step 2, the operator interactively selects the airplane number through the page of the early warning and flight parameter display module, further determines a resolving analysis dependency package matched with the selected airplane number, stores all sub-item paths in the resolving analysis dependency package into a database, and the resolving analysis dependency package comprises a data processing library and a data file, wherein the data processing library comprises: resolving DLL, calibrating DLL and criterion DLL, wherein the data file comprises: calibration files, original data files, calculation data files, criterion result files and the like. Actually, the flight parameter data resolving analysis is carried out based on the resolving analysis dependency package, and specifically includes three processes of data resolving, data calibrating and criterion analysis.
Step 3, next, after selecting and determining the resolving analysis dependent package, the system loads the resolving analysis dependent package, and the loading process actually refers to the loading and connecting process of the dynamic link library (.

In order to ensure the safety in the data transmission process, after the data is acquired by the flight parameter data acquisition equipment, the flight parameter data is packaged in the form of binary data frames through a certain protocol, so that after the flight parameter data is acquired by the resolving analysis module, resolving is also required to be performed according to an agreed flight parameter resolving protocol (namely, the flight parameter resolving protocol specified in the resolving DLL in the loaded resolving analysis dependency package, and different resolving DLLs are required to be generated by different resolving protocols), wherein the agreed flight parameter resolving protocol limits the number of bytes occupied by the flight parameters, the positions of the bytes occupied by the flight parameters, a flight parameter calculation formula, a calculation coefficient, a calibration standard and the like. When data is resolved, firstly, the flight parameter data of the corresponding position is provided from the binary data frame, then based on the corresponding flight parameter resolving protocol, the general flight parameter data is obtained through calculation and calibration, and the resolving process specifically comprises the following steps:

7. An airborne intelligent early warning method is characterized by comprising the following steps:
receiving flight parameter data, and storing the received flight parameter data into a flight parameter original data file; reading flight parameter data, namely binary data frames, in a flight parameter original data file, performing resolving analysis by using a resolving analysis dependency package loaded during initialization and an agreed flight parameter resolving protocol to obtain general flight parameter data, and storing the general flight parameter data into a database; the agreed flight parameter resolving protocol limits the number of the flight parameter occupied bytes, the positions of the flight parameter occupied bytes, a flight parameter calculation formula, a calculation coefficient and a calibration standard;
reading general flight parameter data in a database, judging and early warning an overrun event, and visually displaying the flight parameter data, a judgment result and an early warning grade;
before the onboard intelligent early warning method is executed, the method further comprises the following steps:
initializing a system log and initializing database connection;
based on the selected airplane number, determining a solution analysis dependency package matched with the selected airplane number, and storing all sub-item paths in the solution analysis dependency package into a database, wherein the solution analysis dependency package comprises a data processing database and a data file, and the data processing database comprises: resolving DLL, calibrating DLL and criterion DLL, wherein the data file comprises: calibrating a file, an original data file, a resolving data file and a criterion result file;
loading a resolving analysis dependent packet, creating a data receiving module example, loading the resolving analysis dependent packet by relying on the resolving analysis dependent packet, and executing the airborne intelligent early warning method.
