Description

TECHNICAL FIELD

[0001] The application belongs to the field of avionics, and relates to a multi-load intelligent identification software upgrading system and method. BACKGROUND

[0002] At present, the development trend of aviation equipment is to vigorously promote the generalization, serialization and modularization of unmanned aerial vehicles, and to reduce the cost of unmanned aerial vehicles. Further, higher requirements are put forward for the multi-load software management of cluster unmanned aerial vehicles, i.e., from one type of one load to one type of multiple loads, and the modularization and standardization design of task loads. The composition of load software becomes more complex and flexible. Therefore, it is urgent to design a multi-load intelligent identification software upgrading method for the software management and control of modularized loads. SUMMARY

[0003] PURPOSE OF THE INVENTION The general unmanned aerial vehicle system can improve the consumability, generalizability, high efficiency and cost ratio, and the risk bearing capacity and survival ability can be effectively enhanced. The task load software security and use convenience can be improved, and the management and adaptation ability of multi-task loads can be effectively enhanced. Therefore, it is necessary to carry out the modularization design of task loads, the access management design of task loads, and the independent upgrading design of task loads. The management ability and adaptation ability during the task load work can be effectively improved by designing a multi-load intelligent identification software upgrading method.

[0004] TECHNICAL SCHEME A multi-load intelligent identification software upgrading system is composed of a launch and control device, a comprehensive control task computer, modularized loads and an intelligent identification unit. The launch and control device selects the software file to be upgraded through an upgrading interface, sends the software file to the comprehensive control task computer through Ethernet, and receives the handshake reply information sent by the comprehensive task computer. The comprehensive task computer receives the software file sent by the launch and control device, forwards the upgrading file to the intelligent identification unit according to the upgrading process, and receives the handshake reply information sent by the intelligent identification unit. The intelligent identification unit receives the software file sent by the comprehensive task computer, upgrades the upgrading file to the corresponding storage address according to the load type and manufacturer code reported by the task load, and completes the software upgrading. The intelligent identification software serves different load use scenarios and runs in the intelligent identification unit. The launch and control device, the comprehensive control task computer, the modularized loads and the intelligent identification unit are connected through Ethernet.

[0005] A multi-payload intelligent identification software upgrade method is proposed. Based on the mission payload of the unmanned aerial vehicle and the working mode of the intelligent identification unit, the intelligent identification software upgrade workflow is designed; the packaging format and operation requirements of the upgrade file are designed according to the composition relationship of the intelligent identification software; the upgrade device and the intelligent identification unit communicate with each other via Ethernet; and the upgrade file is transmitted and burned according to the software upgrade process, thereby realizing the online upgrade function of the intelligent identification software.

[0006] Furthermore, the following steps are included: Step 1: Define the software file header; The software file header is defined as follows: 1> The software package that needs to be upgraded in the intelligent recognition unit includes the intelligent recognition unit application software, the intelligent recognition unit model library, and the intelligent recognition unit underlying software. Furthermore, in step one, the software type is distinguished by the software task code: 0x0651 represents application software, 0x0652 represents underlying software, and 0x0653 represents model library. 2> The number of modules to be upgraded refers to the number of modules in the upgrade file, with a maximum of 10. 3> The software version number indicates the version number of the upgraded software; 4> Module type indicates the type of the upgrade module, including the manufacturer code and the software category to which the module belongs; 5> The module start address indicates the offset position of the module in the software file.

[0007] 6> CRC32 checksum refers to the CRC32 checksum of the software data body and all module data headers and module data bodies. 7> Software data body byte length, used to determine whether the transmission is complete.

[0008] Step two, the module data header is defined as follows: 1> The module file length is equal to the length of the module data body; 2> The meaning of the software task code is consistent with that in the software file header; 3> Module type represents different types of software from different manufacturers. 0x11 represents the application software / underlying module / model library of manufacturer 1, 0x22 represents the application software / underlying module / model library of manufacturer 2, 0x33 represents the application software / underlying module / model library of manufacturer 3, and so on, which can accommodate a total of 10 different module types. 4> The module version number indicates the sub-version number to which the module belongs; 5> CRC32 checksum indicates the CRC checksum of the module's data body; Step 3: Based on the file format in Step 2, package the various software modules that need to be upgraded into the application software to be upgraded, the model library to be upgraded, and the underlying software to be upgraded. You can select the packaged upgrade file according to the type of this upgrade.

[0009] Furthermore, step four involves the intelligent identification unit running two processes after power-on: a load identification handshake program and a load software upgrade program. When the ground device issues a software upgrade command, the intelligent identification unit's load identification handshake program and load application program close, and the upgrade process begins. If no upgrade command is received within 30 seconds, and the load handshake is successful, the load application process executes normally. The two load processes correspond to two software branches: one is the intelligent identification unit connecting to the load and performing load identification through the load identification handshake program, then starting the corresponding load application program; the other is the intelligent identification unit's load software upgrade program.

[0010] Furthermore, step five involves upgrading the software of the intelligent identification unit. This is done through the payload software upgrade program branch. After receiving the software upgrade instruction via 100Mbps Ethernet, the intelligent identification unit upgrade program parses the valid data in the instruction and completes subsequent instruction replies, data reception and storage, program burning, and whether the burning is complete.

[0011] Furthermore, in step five, the specific upgrade steps are as follows: 1> When the intelligent identification unit upgrade program receives a "software upgrade command" from the task machine and the operation type is "program read / write", it responds to the command, indicating that it is ready to start the upgrade; 2> When the intelligent identification unit upgrade program receives the "data transmission command" issued by the task machine and the operation type is "program read and write", the task machine sends the upgrade file data to the intelligent identification unit in frames. After the intelligent identification unit receives each frame of data, it buffers the data and responds. After the task machine receives the response, it continues to send the next frame until all upgrade file data packets are sent. 3> When the intelligent identification unit upgrade program receives the "data transmission complete command" issued by the task machine and the operation type is "program read / write", it responds to the instruction, indicating that the complete upgrade file has been received; 4> After the intelligent identification unit verifies the integrity of the entire upgrade data package at the bottom layer, it distinguishes the intelligent identification unit software according to the software task code.

[0012] Furthermore, step 4> of step five includes: a> If it is an intelligent recognition unit application software or model library file, the upgrade files of each manufacturer are obtained by parsing the "number of modules to be upgraded", "module start address" in the software file header and "length" in the module data header, and the upgrade files of each manufacturer are placed in the system's specified location. The name of each upgrade file is the same as the file name in the "software upgrade command". If it is low-level software, the intelligent identification unit parses the upgrade files of each low-level module according to the "number of modules to be upgraded", "module start address" in the software file header and "length" in the module data header, and distributes them to FPGA, NPU and DSP according to different types. Then each processor performs the low-level program burning and reports the upgrade result back to the upgrade software after the burning is completed. Furthermore, step six is ​​also included: when the intelligent identification unit upgrade program receives the "software readback command 1" issued by the task machine, it judges the burning status of each software. If all software has been burned, it replies to the task machine that the data preparation is complete; if a certain software has not been burned, it replies to the task machine that the data preparation is not complete. Furthermore, step seven is also included: when the intelligent identification unit application software receives the "software readback command 2" issued by the task machine, it judges the burning results of each software. If all software is burned successfully, it replies to the task machine that the burning process has ended normally; if a certain software is burned abnormally, it replies to the task machine that the burning process has ended abnormally.

[0013] Technical effect The beneficial effects of this invention are: 1> It designs a multi-payload intelligent identification software upgrade method, realizes the online upgrade function of modular payload software of unmanned aerial vehicles, and enhances the stability and ease of use of the system; 2> It improves the generalization and modularity of unmanned aerial vehicles. This method conforms to the open system architecture design concept, meets diverse combat needs, promotes the upgrading and leapfrog development of equipment systems, and accelerates the improvement of new combat capabilities.

The embodiments described below with reference to reference are exemplary and intended to explain this invention, and should not be construed as limiting the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. The embodiments of this invention will be described in detail below.

[0016] Based on the mission payload of the unmanned aerial vehicle and the working mode of the intelligent identification unit, design the intelligent identification software upgrade workflow; 2. Based on the composition relationship of the intelligent identification software, design the packaging format and operation requirements of the upgrade file; 3. The upgrade device and the intelligent identification unit use Ethernet communication for interactive communication. According to the software upgrade process in step 1, complete the transmission of the upgrade file, the burning of the upgrade file, and other processes to realize the online upgrade function of the intelligent identification software.

[0017] First, in order to achieve rapid upgrades of multi-load intelligent recognition software, an intelligent recognition software upgrade environment is built, the system composition of which is as follows: Figure 1 As shown in the diagram, the entire system consists of launch and control equipment, an integrated control mission computer, modular payloads, and an intelligent identification unit. The launch and control equipment selects the software file to be upgraded through an upgrade interface, sends it to the integrated control mission computer via Ethernet, and receives a handshake response from the integrated mission computer. The integrated mission computer, upon receiving the software file from the launch and control equipment, forwards the upgrade file to the intelligent identification unit according to the upgrade process and receives a handshake response from the intelligent identification unit. The intelligent identification unit, upon receiving the software file from the integrated mission computer, upgrades the file to the corresponding storage address based on the payload type and manufacturer code reported by the mission payload, completing the software upgrade. The intelligent identification software serves different payload usage scenarios and runs within the intelligent identification unit; the launch and control equipment, integrated control mission computer, modular payloads, and intelligent identification unit are all connected via Ethernet.

[0018] Second, the software running in the intelligent recognition unit is quite complex, so the format of the software upgrade files for the intelligent recognition unit needs to be specified. The specific format is as follows: Figure 2 As shown, the entire software file consists of a software file header and an upgrade module. The upgrade module consists of a module data header and a module data body. The software file header is defined as follows: 1> The software packages that need to be upgraded in the intelligent recognition unit include intelligent recognition unit application software, intelligent recognition unit model library, and intelligent recognition unit underlying software. This software type is mainly distinguished by the software task code: 0x0651 represents application software, 0x0652 represents underlying software, and 0x0653 represents model library. 2> The number of modules to be upgraded refers to the number of modules in the upgrade file, with a maximum of 10. 3> The software version number indicates the version number of the upgraded software; 4> Module type indicates the type of the upgrade module, including the manufacturer code and the software category to which the module belongs; 5> The module start address indicates the offset position of the module in the software file.

[0019] 6> The CRC32 checksum represents the CRC32 checksum of the software data body (including both the module data header and the module data body); 7> Software data body byte length, used to determine whether the transmission is complete (including all module data headers and module data bodies).

[0020] The module data header is defined as follows: 1> The module file length is equal to the length of the module data body; 2> The meaning of the software task code is consistent with that in the software file header, indicating the software type: 0x0651 indicates application software, 0x0652 indicates low-level software, and 0x0653 indicates model library; 3> Module type represents different types of software from different manufacturers. 0x11 represents manufacturer 1 (application software / underlying module / model library), 0x22 represents manufacturer 2 (application software / underlying module / model library), 0x33 represents manufacturer 3 (application software / underlying module / model library)... and so on, which can accommodate a total of 10 different module types; 4> The module version number indicates the sub-version number to which the module belongs; 5> CRC32 checksum indicates the CRC checksum of the module's data body; Third, according to the file format in section two, package the various software modules that need to be upgraded into application software that needs to be upgraded, model library that needs to be upgraded, and underlying software that needs to be upgraded. You can select the packaged upgrade file according to the type of this upgrade. Fourth, the entire intelligent recognition unit software execution process is as follows: Figure 3As shown, after the system powers on, the intelligent identification unit runs two processes: a load identification handshake program and a load software upgrade program. When the ground device issues a software upgrade command, the intelligent identification unit's load identification handshake program and load application program close, and the upgrade process begins. If no upgrade command is received within 30 seconds, and the load handshake is successful, the load application process executes normally. The two load processes correspond to two software branches: one is the intelligent identification unit connecting to the load and performing load identification through the load identification handshake program, and then starting the corresponding load application program; the other is the intelligent identification unit's load software upgrade program.

[0021] Fifth, the software upgrade of the intelligent identification unit is carried out from the payload software upgrade program branch, and the specific process is as follows: Figure 4 As shown. After receiving the software upgrade command via 100Mbps Ethernet, the intelligent identification unit upgrade program parses the valid data in the command and completes subsequent functions such as command reply, data reception and storage, program burning, and whether the burning is complete. The specific steps are as follows: 1> When the intelligent identification unit upgrade program receives a "software upgrade command" from the task machine and the operation type is "program read / write", it responds to the command, indicating that it is ready to start the upgrade; 2> When the intelligent identification unit upgrade program receives the "data transmission command" issued by the task machine and the operation type is "program read and write", the task machine sends the upgrade file data to the intelligent identification unit in frames. After the intelligent identification unit receives each frame of data, it buffers the data and responds. After the task machine receives the response, it continues to send the next frame until all upgrade file data packets are sent. 3> When the intelligent identification unit upgrade program receives the "data transmission complete command" issued by the task machine and the operation type is "program read / write", it responds to the instruction, indicating that the complete upgrade file has been received; 4> After the intelligent identification unit verifies the integrity of the entire upgrade data package at the bottom layer, it distinguishes the intelligent identification unit software according to the software task code.

[0022] a) If it is an intelligent recognition unit application software or model library file, the upgrade files of each manufacturer are obtained by parsing the "number of module upgrades" and "module start address" in the software file header and the "length" in the module data header, and the upgrade files of each manufacturer are placed in the system's designated location (see [location details]). Figure 3 (Location of application / model library files), each upgrade file is named the same as the filename in the "Software Upgrade Command"; If it is low-level software, the intelligent identification unit parses the upgrade files of each low-level module according to the "number of modules to be upgraded", "module start address" in the software file header and "length" in the module data header, and distributes them to FPGA, NPU and DSP according to different types. Then each processor performs the low-level program burning and reports the upgrade result back to the upgrade software after the burning is completed. 6. When the intelligent identification unit upgrade program receives the "software readback command 1" issued by the task machine, it judges the burning status of each software. If all software has been burned, it replies to the task machine that the data preparation is complete; if a certain software has not been burned, it replies to the task machine that the data preparation is not complete. 7. When the intelligent identification unit application software receives the "software readback command 2" issued by the task machine, it judges the burning results of each software. If all software is burned successfully, it replies to the task machine that the burning process is normal and has ended; if a certain software is burned abnormally, it replies to the task machine that the burning process is abnormal and has ended.
