[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0044] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0045] Embodiment 1
[0046] It should be noted that in the current aviation industry, there are different data transmission buses in the software of many airborne systems. During the data transmission process, the airborne software needs to encode the source data into a data stream form that can be transmitted by the bus. The software that receives the data through the communication system forwarding needs to decode the received binary data stream, deserialize the binary data, and parse it into the structure required by the user. In the current airborne software, the interface control documents (ICD) of different data transmission buses have different definitions, and the size of some fields should also be appropriately converted according to the source data. Therefore, the encoding and decoding of the data are also different, and the data needs to be converted through multiple groups of different interface configuration files in the entire communication system, which leads to poor versatility and flexibility of data encoding and decoding and low efficiency. In the design of the interface configuration file, due to the limitations of bus protocol, data range, data type, resolution or unit, the physical quantity often needs to be converted in a certain form before it can be transmitted through the data bus. Therefore, the conversion of physical quantity and data quantity needs to be supported in the data encoding and decoding process. In current airborne systems, different bus protocols often use different byte orders, and some fields need to use big-endian or little-endian. Fixed protocol configurations cannot be dynamically converted during software execution, and often require software code modification to implement. When the amount of data is large, the number of fields that need to be converted also increases. Therefore, when the amount of data is large, a custom ICD is configured. By configuring different field attributes, the data can be efficiently encoded through the currently configured attributes during the encoding process.
[0047] The present invention provides a method for customizing ICD configuration and data acquisition based on network communication, comprising the following steps:
[0048] Step (1): Configure a custom ICD according to user requirements and generate an ICD configuration file.
[0049] It should be noted that this configuration method supports all data types, such as char, unsigned char, short, unsigned short, int, unsigned int, long, unsigned long, etc. This configuration method supports bit-by-bit configuration, configuring single or multiple bits, and automatically filling up if the bits are less than 8 bits during the configuration process. The ICD configuration file contains the main fields such as the current frame identifier, message ID, message length, heartbeat word, data content, data check, etc. Each field in the ICD configuration file contains configuration inherent attributes, such as UUID (Universally Unique IDentifier), data type, field length, enumeration value, field offset, bit length, bit offset, big and small end, data range, unit, etc. In the process of adding fields, some attributes such as UUID, data type, field length, field offset, bit length, bit offset will be automatically generated, and some attributes need to be manually selected and configured, including big and small end, data range, enumeration value, unit, etc. Save the custom ICD configuration information to a file, and the supported file formats include XML or JSON.
[0050] Step (2): Generate an interface configuration file based on the ICD configuration file, and the fields of the ICD configuration file are bound to the fields of the interface configuration file through a unique UUID.
[0051] It should be noted that the interface configuration file contains descriptions of ICD data, display type and other information; the interface configuration file configures the interface display content according to the user interface display requirements. The prerequisite for this method is that the custom ICD configuration has been completed. This configuration supports most basic data display types, such as: decimal value display method, hexadecimal value display method, enumeration value display method, progress bar display method, waveform display method, switch display method, etc. By selecting the configured data field, manually configure the display method of the field. Each selected configuration item contains inherent attributes such as UUID, display type, display position, enumeration value, data range, unit, etc. In the process of selecting the field, some attributes such as UUID and display type are automatically generated. The UUID of the interface configuration file is associated with the currently selected UUID of the configured ICD configuration file. Some attributes need to be manually configured, including data range, unit, enumeration value, display position, etc. The file formats supported by the interface configuration file include XML or JSON.
[0052] Step (3): First read the ICD configuration file and save the field attributes in memory.
[0053] Step (4): Receive data information and split it to obtain the frame identifier, match the corresponding ICD configuration file in the memory through the frame identifier, and parse the data information according to the field attributes of the corresponding ICD configuration file; read the interface configuration file to generate a display interface, traverse the interface configuration file, obtain the parsed field value by matching the UUID of the current field, and display the field value using the display method of the interface configuration file by matching the current field display type.
[0054] It should be noted that the display control system and the bus communication system exchange data information through network communication. For the binary data received by the display control system, it is necessary to split the original data according to the data frame format provided by the ICD configuration file, obtain the frame identifier, match the corresponding ICD configuration file by matching the frame identifier, and then parse the binary data. The binary data is split according to the attribute data type, field length, field offset, bit length, and bit offset of the configuration field, and the split data is processed and assigned according to the configured big and small ends, the field data conversion is performed, and the parsed results are sent to the display module.
[0055] The display module reads the interface configuration file to generate a display interface, and the display module traverses the interface configuration file, obtains the parsed field value by matching the UUID of the current field after receiving the data, and displays the field value in the display method of the interface configuration file by matching the current field display type.
[0056] Among them, the decimal value display method is to obtain the parsed field value by matching UUID, and display the parsed value in decimal value format; the hexadecimal value display method is to obtain the parsed field value by matching UUID, and display the parsed value in hexadecimal format; the enumeration value display method is to obtain the parsed field value by matching UUID, and display the parsed value in enumeration value format by matching the configured enumeration value; the progress bar display method is to obtain the parsed field value by matching UUID, and display the parsed value in progress bar format; the waveform display method is to obtain the parsed field value by matching UUID, and periodically plot the parsed value on the waveform graph; the switch type display method is to obtain the parsed field value by matching UUID, and display the parsed value in switch quantity format.
[0057] Step (5): The data packet to be sent needs to match the custom ICD of the ICD configuration file through the frame identifier, and the data packet to be sent is serialized in the format of the custom ICD and then sent.
[0058] According to the end mode attribute in the matching ICD configuration file, the data information big-small end conversion interface is obtained, each field in the ICD configuration file is traversed in turn, the physical quantity is converted into the original value according to the attribute of each field in the ICD configuration file, the end mode conversion interface is called, the original value is converted into binary data, a binary data packet is generated, and the binary data packet is sent through the network.
[0059] It should be noted that the program code for implementing the method of the present disclosure can be written in any combination of one or more programming languages. These program codes can be provided to a processor or controller of a general-purpose computer, a special-purpose computer or other programmable data processing device, so that when the program code is executed by the processor or controller, the functions / operations specified in the flow chart and / or block diagram are implemented.
[0060] It is worth mentioning that by configuring the custom ICD for network communication and implementing custom data decoding and encoding, the problem of reconstructing the code when the software communication protocol changes is solved, thus improving the flexibility and versatility of the software.
[0061] Secondly, different bus protocols often use different endian and little-endian modes to store data, and little-endian conversion is required during the encoding and decoding process. If the big-endian and little-endian modes of the data change, the communication data can be dynamically adapted by modifying the big-endian and little-endian attribute configurations in the ICD configuration file to improve the efficiency of encoding and decoding formatted data in the airborne system.
[0062] In addition, the information of the custom ICD internal data items and the interface controls are combined to automatically establish a data channel between the custom ICD internal data items and the interface controls to achieve framework-level reuse. The display control system can be reused between different projects by replacing the interface configuration file, which is more scalable than traditional process-oriented systems.
