Embedded System of Aircraft for Test and Flight Simulation

The present invention stores an embedded system of aircraft (Flight Simulation & Test) and its automatic value table (CVT) and IN OUT Mapping (IOMAP) automatic generation method and the program by the method A recording medium, more specifically, an aircraft embedded system that automatically generates CVT and IOMAP, which is an important factor in SIL development, in a database (DB) and minimizes creation time and manpower, and its CVT and IOMAP automatic. A recording medium storing a generation method and a program according to the method.

In general, after manufacturing the aircraft and before performing the test flight of the aircraft to check the operation of the equipment mounted in the aircraft to determine whether there is an abnormality, the aircraft to enable repair and replacement of the equipment in the event of an error Onboard equipment testing is mandatory.

In order to test the onboard equipment, the test apparatus is conventionally connected to the check terminals provided in the onboard equipment of the aircraft, and the test result data transmitted from each test apparatus is collected, and the normal operation of the onboard equipment is performed based on the data. Determine whether or not.

The scope of the software in SIL can be seen as an electric power model that simulates real avionics, an operating environment program that operates the system, and an analysis program that can analyze signals such as actual equipment and simulation models. Such a program is first developed based on a single signal database (DB) covering all simulated and monitored signals. This signal database is called Current Value Table (CVT) in SIL, and each program is composed by reading and writing a value to this CVT signal. It also runs a program called IOMAP (IN OUT Mapping), which connects the CVT's information to the actual signals of the discrete, analog, UART, and MILBUS devices. When these two programs operate normally, the data inside the programs move smoothly and the actual electrical signals can flow into the real equipment.

CVT is a database used by the entire system and acts like a global variable that is applied to the entire public. In other words, the criteria for creating a CVT are the types of variables (int, double, signed, unsigned, and fload), variable names, variable characteristics (array or fifo, single), and error injection. This should be prepared according to the CVT generation criteria.

In the past, a tool called devConfig was used to generate CVT and IOMAP. However, it took considerable time and manpower to generate as many as 17,000 signals using this tool.

In addition, there is a lot of concern that humans generate each CVT and IOMAP by hand. In this case, even if only 1% of mistakes occur, 170 CVTs will be generated incorrectly.

The present invention has been proposed to solve the above technical problem, and minimizes time and manpower by automatically generating CVT and IOMAP based on the database input value after inputting all data recorded in ICD into SQL-based database. The purpose of the present invention is to provide an aircraft embedded system, a method of automatically generating CVT and IOMAP, and a recording medium storing the program according to the method.

In addition, another object of the present invention and aircraft embedded system that automatically selects each radio button in the entire GUI program and make (Make), each selected logic is implemented to automatically generate the final result CVT file and IOMAP file and its The present invention provides a method for automatically generating a CVT and IOMAP and a recording medium storing a program according to the method.

In addition, another object of the present invention is to develop a complete GUI program with wxPython and to build a code for generating CVT and IOMAP in Python, a recording medium storing the CVT and IOMAP automatic generation method and the program by the method To provide.

In addition, another object of the present invention is an aircraft composed of a logic for generating CVT and IOMAP for the simulated signal, and a GUI for automatically generating the CVT and IOMAP for monitoring the communication data between the real equipment or the simulated equipment and manages the overall selection The present invention provides an embedded system, a method for automatically generating CVT and IOMAP, and a recording medium storing a program by the method.

Then, the CVT / IOMAP conversion automatic generation tool 100 will be described in detail with reference to the accompanying drawings.

CVT / IOMAP conversion auto-generation tool

2 is a conceptual diagram of a CVT and IOMAP connection according to the present invention, Figure 3 is a block diagram of a CVT and IOMAP automatic generation tool.

The CVT and IOMAP connection concept, as shown in Figure 2, I / O real by generating a CVT and IOMAP for monitoring the communication data between the Avionics Model (mock equipment) and Real Avionics (real equipment) It is configured to input and output to a hardware device.

As shown in FIG. 3, the CVT and IOMAP automatic generation tool 100 may include a CVT / IOMAP generation GUI 110, a remote terminal (RT) CVT generation logic 120, and an RT IOMAP generation. Logic 130, BM (Bus Monitoring: Real MILBUS monitoring signal component) CVT generation logic 140, BM IOMAP generation logic 150, and SQL-based database 160 is configured to include.

Here, the CVT / IOMAP generation GUI 110 is an entire program for generating the CVT / IOMAP, and selects and controls the logic 120 to 150. The CVT / IOMAP generation GUI 110 program was developed through wxPython, and when each radio button is selected and a make is performed, each selected logic is implemented to generate a final result CVT file and IOMAP file ( 6 to 8).

The RT CVT generation logic 120 is logic for generating a CVT for the simulated signal, and the RT IOMAP generation logic 130 is logic for generating an IOMAP for the simulated signal. In addition, the BM (Bus Monitoring) CVT generation logic 140 is logic for generating a CVT for monitoring communication data between the real equipment or the simulation equipment, and the BM IOMAP generation logic 150 is the communication between the actual equipment or the simulation equipment. Logic that creates IOMAP to monitor data.

The CVT and IOMAP automatic generation tool 100 program automatically generates a CVT for the simulated monitoring signal for the MILBUS signal, which accounts for 90% of the total signal. Automatic generation criteria were generated according to the SQL-based database 160 generated based on the current Interface Control Document (ICD).

The IOMAP is a program that connects the CVT data generated by the system to the actual hardware. By operating this program, the actual MILBUS communication and the discrete / analog communication are possible. In other words, it is the most important part that exchanges logical signals with electrical signals. The program automatically generates the MILBUS portion, which makes up more than 95% of this IOMAP. Automatic generation criteria were generated according to the SQL-based database 160 generated based on the current ICD.

Feature-specific configuration of CVT and IOMAP auto-generation tools

Figure 4 is a functional block diagram of the CVT and IOMAP automatic generation tool according to the present invention.

As shown in FIG. 4, the CVT and IOMAP automatic generation tool 100 includes an input unit 110, a processing unit 180, and an output unit 190.

When the generation command is issued through the radio button and the make button in the GUI corresponding to the input, the input unit 110 processes the selected item accordingly.

The processing unit 180 is a part for processing to generate an RT CVT file, an RT IOMAP file, a BM CVT file, and a BM IOMAP file, respectively, and the output unit 190 processes each CVT and IOMAP file. This is the output part.

Here, the process of generating the RT CVT file is as follows.

First, the RT CVT is initialized and then connected to the SQL-based database 160 to extract related data. After analyzing the characteristics of each extracted signal, the RT CVT file is created after error injection is allowed to be patched later.

Next, a process of generating the RT IOMAP file is as follows.

First, RT IOMAP generation is initialized and then the SQL-based database 160 is accessed, and then relevant data is extracted. The RT IOMAP file of the input / output (IN / OUT) single signal is generated by removing the duplicate sub address (SA) from the extracted related data.

Next, the process of generating the BM CVT file is as follows.

First, after initializing the BM CVT generation, the next relevant data belonging to the SQL-based database 160 is extracted. And after analyzing the characteristics of each extracted signal of the relevant data, all the signals of blocks, words, and bits are monitored so that they can be monitored in units of blocks, words, and bits. Create a BM CVT file after disallowing error injection to prevent further patching.

Finally, the process of generating the BM IOMAP file is as follows.

First, after the BM IOMAP generation is initialized, it is connected to the SQL-based database 160 and then extracts related data. Then, all signals of the extracted relevant data are generated, and blocks and words are generated to be monitored in units of blocks and words, and then BM IOMAP files are generated.

In general, the CVT has similar RT and BM logic, but in the case of the RT, error injection is allowed so that a patch can be made later, whereas in the case of the BM, error injection is not allowed. In the case of the BM, a signal in units of blocks and words should be identified, and thus a CVT corresponding thereto is generated.

On the other hand, the IOMAP has a lot to be considered differently from the CVT. The main task is to match CVT according to RT and SA numbers. This part has a big difference between RT and BM. Since the RT does not allow duplicate SAs, one side of the data must be given up. However, in the case of the RT, it is not necessary to do so, but in the case of the BM, since the monitoring should be possible in units of blocks and words, the logic of the part should be considered. Through this logic, each CVT and IOMAP file is generated as the final result.

How to automatically generate CVT and IOMAP

5 is a flowchart illustrating an operation of automatically generating a CVT and an IOMAP according to the present invention.

Then, select the RT CVT, RT IOMAP, BM CVT, BM IOMAP generation menu through the radio box in the main screen (steps S30, S40, S50, S60) and make the respective execution routines. (Steps S35, S45, S55, S65).

CVT and IOMAP information to be generated in each routine is retrieved from the SQL-based database 160. After the generation logic is performed based on the imported data, the result is output, and the program is terminated through the EXIT menu (step S70).

After selecting one of RT CVT, BM CVT, Model SID, RT IOMAP, and BM IOMAP as a button on the main screen 200 of the CVT and IOMAP automatic generation program, and clicking the make button 240, the selected content with the button The generation routine is executed for. At this time, the information of the CVT and IOMAP to be generated in each routine is imported from the SQL-based database 160, and after generating the generation logic based on the imported data, the corresponding file is automatically generated. In this case, the generated file is output as shown in the screens of FIGS. 7 and 8.
