Description

A Rapid Development Method of Special Ground Detection Software for Inertial Navigation System

technical field

The invention belongs to the field of research and development of special ground detection software for inertial navigation systems.

Background technique

The special ground detection software for the inertial navigation system is a software for testing and verifying the external interface of the inertial navigation system. It can simulate various avionics equipment cross-linked with the inertial navigation system to send data to the inertial navigation system, and can also send the inertial navigation system to other external devices. The data is displayed in real time, which has played an important role in the work of inertial navigation test verification.

Due to the complexity and changeability of the external interface of the inertial navigation system, the original development steps of the inertial navigation ground detection software are as follows: first, compile the bus data sending and receiving driver according to the ICD information and hardware configuration; second, manually encode the sending data and receiving data one by one according to the ICD file ; Thirdly, the ground detection software is generated after the driver is fused with the code generated in the second step. The disadvantage of this design method is that the ground detection software development efficiency is low, time-consuming, and manpower-intensive when the interface of the inertial navigation system has a large difference. The development efficiency of detection software is low.

This method not only improves the efficiency of design and development, but also enhances the reliability of the designed products.

The technical solution adopted by the present invention is a rapid development method for special ground detection software for inertial navigation systems, which is characterized in that,

The first step is to use the data processing module to extract the data information required by the ground detection software from the project database;

In the second step, the application logic module selects the input operation and data display components required by the project based on the data information extracted in the first step, and at the same time combines the software and hardware isolation component library to automatically generate the corresponding ground detection software.

Further, the data processing module extracts the data information required by the ground detection software from the project database, including the following steps:

The first step is to access the project database and extract the PACKET data according to the bus type, which contains information such as the number, name, length, period, and address of the PACKET;

The second step is to extract DATA data from PACKET data, including DATA data name, resolution, data type, data length, high and low word data order and other information;

The third step is to extract the BIT data from the DATA data, including information such as the value of each BIT data and the meaning it represents;

Further, the application logic module selects the input operation and data display components required by the project based on the data information extracted in the first step, and combines the software and hardware isolation component library to automatically generate the corresponding ground detection software. The steps are as follows:

The first step is to apply the logic module to extract the data components corresponding to each data received by the inertial navigation from the input operation component library of the ground detection software based on the extracted data information, such as the radio box component corresponding to the control command received by the inertial navigation And the data input components corresponding to the initial latitude and longitude data loading of inertial navigation;

In the second step, the application logic module extracts the display components corresponding to the data sent by the inertial navigation from the data display component library of the ground detection software based on the extracted data information, such as the validity indicator component used to display the validity of the inertial navigation data and Table components and drop-down box components that display all data sent by inertial navigation;

In the third step, the application logic module transmits the address, length, cycle and other information of the PACKET data to the software and hardware isolation component library according to the extracted data information, and constitutes the calling code of the software and hardware isolation driver of the ground detection software;

The fourth step is to apply the logic module to automatically generate the code that analyzes the bus data and displays it in the corresponding data display component according to the extracted data information and according to the characteristics of the bus data sent by the inertial navigation system;

The fifth step is that the application logic module automatically generates the code for extracting data from the input operation component and converting it into the bus format according to the extracted data information and the characteristics of the bus data received by the inertial navigation system.

The present invention has advantages and beneficial effects: the advantage of this method is: firstly, the ICD information is directly extracted from the project database through the data processing module, avoiding the process of people directly browsing the ICD file to extract the required information, thereby reducing the error rate;

Secondly, the application logic module automatically generates the corresponding codes for receiving, sending, data processing and displaying based on the data information required by the ground detection software extracted from the database, which avoids the repetitive coding work of the designer and realizes the special purpose of the inertial navigation system. Rapid design and development of ground detection software.

A rapid development method of special ground detection software for inertial navigation system greatly reduces the workload of designers, avoids the problem of high error rate of manual coding, and reduces the financial and human consumption of a large number of test verification links.
