Description

Technical Field

[0001] This invention relates to the field of data storage technology for avionics systems, and specifically to a reliable storage and recording method, system, and related products based on airborne networks. Background Technology

[0002] In the development of avionics technology, avionics systems have gradually evolved from early discrete and integrated systems to a more integrated and even highly integrated stage. The types of subsystems have continued to increase, covering key modules such as flight control, flight management, mission systems, navigation systems, and air data systems. With the increase in system integration, the various subsystems need to achieve a large amount of data communication and interaction through airborne networks. This data needs to be reliably stored for subsequent ground diagnostics and mission review. An avionics system includes a mission system, a navigation system, an air data system, and a display and control system. The core processing system (IPC) of the avionics system includes four general data processing modules (DPM), one large-capacity storage module (SDM), and two airborne network switching modules (NSM). All other subsystems are connected to the switching modules via fiber optic cables to ultimately realize the data exchange and processing of the entire airborne network. The large-capacity storage module in the IPC is responsible for the data capture and recording function of the entire airborne network, and completes network bus monitoring data (FC network bus monitoring data and GJB289A bus monitoring data), flight parameter information, central maintenance information, central maintenance fault information, and flight management data. The module is designed with a 1T electronic disk, using an embedded high-reliability transactional file system, to record and store the communication data of the entire airborne network.

[0003] Currently, large-capacity storage modules (SDMs) are typically configured with fixed storage strategies, such as allocating disk space using a preset directory structure or uniformly recording data from all connected subnets. However, this traditional storage method has the following drawbacks: First, storage resource allocation lacks dynamic adaptability. Due to the differences in data content that different flight missions focus on, fixed directories and space allocation can easily lead to non-critical data occupying too much disk space, while critical data storage space is insufficient, reducing disk space utilization efficiency. Second, there is a lack of real-time awareness of node online status and dynamic link management mechanisms. When subsystem nodes go offline or mission requirements change, the data recording strategy cannot be adjusted in a timely manner, which may result in data loss, storage redundancy, or continuous writing of invalid data.

[0004] Existing storage solutions do not coordinate the planning of subsystem response request information and remaining disk space, resulting in insufficient targeting and reliability of critical data storage, making it difficult to meet the stringent requirements of highly integrated airborne networks for reliable, efficient, and flexible data storage. Summary of the Invention

[0005] The purpose of this invention is to provide a reliable storage and recording method, system, and related products based on airborne networks, in order to overcome the problem that existing airborne networks do not coordinate the planning of subsystem response request information and disk space during flight, resulting in insufficient targeting and reliability of critical data storage.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution: A trusted storage and recording method based on an airborne network includes the following steps: S1. Obtain the online status of all nodes in the online subsystems, and send a broadcast link request message to the online subsystems according to the node online status. The online subsystems that receive the broadcast link request message send a response request message according to the required task. S2. Obtain the remaining disk space, dynamically plan and allocate the corresponding directory structure and disk space for each online subsystem based on the response request information of the online subsystem, and send the startup data sending command to the online subsystem that has been allocated the corresponding directory structure and disk space. S3. Determine whether data has been received from the online subsystem. If yes, store the data in the corresponding directory structure and disk space. If no, return to step S1.

[0007] A further improvement of the present invention is that it also includes step S4: Monitor the operation of the airborne network and collect statistics, and take fault handling actions based on the statistics.

[0008] A further improvement of this invention is that when monitoring and statistical results determine that the airborne network cannot store data normally, the backup disk space is activated.

[0009] A further improvement of the present invention is that the operation process of the airborne network includes the entire process from power-on to power-off of the airborne network.

[0010] A further improvement of the present invention is that: the storage of data to the corresponding directory structure and disk space is specifically achieved by performing large-capacity data writing operations on the airborne network with time interval thresholds and data throughput thresholds respectively.

[0011] A further improvement of the present invention is that the data storage to the corresponding directory structure and disk space is balanced by using a dual-port RAM ring buffer for data writing.

[0012] The present invention also provides a trusted storage and recording system based on an airborne network, comprising: The first module is used to obtain the online status of all nodes in the online subsystems, send broadcast link request messages to the online subsystems according to the node online status, and the online subsystems that receive the broadcast link request messages send response request information according to the required tasks. The second module is used to obtain the remaining disk space, dynamically plan and allocate the corresponding directory structure and disk space for each online subsystem based on the response request information of the online subsystem, and send the startup data sending command to the online subsystem that has been allocated the corresponding directory structure and disk space. The third module is used to store data in the corresponding directory structure and disk space.

[0013] The present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the trusted storage and recording method based on an airborne network as described above.

[0014] The present invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the trusted storage and recording method based on the airborne network described above.

[0015] The present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the trusted storage and recording method based on an airborne network as described above.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The trusted storage and recording method based on airborne networks provided by this invention enables any device within an airborne network subsystem to access the network at any time and complete data storage and recording functions through dynamic link monitoring and establishment, dynamic disk space allocation and planning, data buffering, and data recording and statistics. Specifically, by acquiring the response request information of online subsystems and combining it with the remaining disk space, the directory structure and disk space of each online subsystem are dynamically planned, ensuring that the allocation of storage resources is precisely matched with the actual task data requirements. This effectively overcomes the lack of dynamic adaptability in storage resource allocation and significantly improves disk space utilization efficiency. By acquiring the online status of all subsystem nodes in real time, link requests are only initiated to online subsystems, and storage is planned based on their responses. When no data is received, the node status is re-sensed to ensure timely response to situations such as node offline and changes in task requirements, dynamically adjusting the data recording strategy to avoid the aforementioned storage anomaly problems. Through the linkage planning of subsystem response request information and remaining disk space, the storage strategy simultaneously matches task data requirements and disk resource status, ensuring priority and reliable storage of critical data, meeting the stringent requirements of highly integrated airborne networks for trusted, efficient, and flexible data storage.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. This is an explanation of the present invention and not a limitation thereof.

[0025] See Figure 1 A trusted storage and recording method based on an airborne network includes the following steps: Step 1) Use the network management function of the switch to complete the status statistics of all online subsystems and broadcast link (LINK_REQUEST) request messages according to the node online status cycle. After receiving the link request, the subsystem responds to it (DATA_REPLY) according to whether there is a record of the required task in the system configuration. Once a response (DATA_REPLAY) is received, proceed to step 2.

[0026] Step 2) Dynamically plan the remaining disk space according to the currently received response requests, allocate the corresponding directory structure and space size to each subsystem, and send the command to start data transmission (DATA_START) to the subsystem after completing the space allocation. After receiving each data packet from the subsystem, send an acknowledgment message (DATA_CONFIRM) to the subsystem and then proceed to Step 3. Otherwise, proceed to Step 1 to re-establish the link request. Step 3) Receive data from each subsystem, allocate a sufficiently large buffer in memory to buffer and count the received data, and perform large-capacity data write operations to disk with two thresholds: time interval and data throughput. Use a dual-port RAM ring buffer to perform balanced data writing and finally store the buffered data to the electronic disk. Step 4) Detect and statistically analyze the entire system operation process from power-on to power-off, and perform corresponding fault handling actions at any time based on the overall system operation status.

[0027] The trusted storage and recording method based on airborne networks provided by this invention enables any device within the airborne network subsystem to access the network at any time and complete data storage and recording functions through dynamic link monitoring and establishment, dynamic disk space allocation and planning, data buffering, and data recording and statistics. It features automatic detection of subsystem devices accessing the network, utilizing effective resources to store and record different types of data during flight, positively contributing to ground flight data playback, flight mission training, and troubleshooting. Airborne devices can access the data recording system at any time. The system automatically detects and establishes a link with the device, allocating space resources to receive data and storing and recording it in real time, dynamically monitoring the recorded data content during the recording process.

[0028] Furthermore, it can easily realize the storage and recording functions of various devices within the airborne network system, which helps to improve ground analysis and playback data, optimize flight missions, and reduce the failure rate; large-capacity data storage and buffering, using dual-port RAM ring buffer, DMA large-block data copying, and data-balanced disk writing operations maximize the performance of the entire data capture and recording software; data detection and statistical functions ensure the authenticity and validity of data recording, and the fault handling function established based on the detection and statistical functions greatly improves the system's reliability and robustness; the system design is comprehensive and effective, and the entire system design is built with a modular approach, which facilitates the reuse of software components, reduces the amount of code, and lowers the development difficulty.

[0029] The specific operation of step 1) is as follows: Step 1.1) The LINK_REQUEST period interval is 500ms. At the same time, the DATA_START and DATA_CONFIRM messages are all short messages. A subsystem status statistics table 1 is established based on whether a response message is received.

[0030] Step 1.2) The DATA_REPLY message needs to include information about the directory to be created and the maximum disk space required; In the specific operation of step 2): Step 2.1) Based on the information in Step 1.2 and the current remaining disk space, dynamically plan the entire disk space and directory structure information, etc. When planning this disk space, allocate backup space to ensure that the data recording function can be completed in abnormal situations. Step 2.2) If the data logging software does not receive data within 5 cycles or the subsystem does not receive the DATA_CONFIRM response packet within 5 cycles, then proceed to Step 1 to restart link establishment.

[0031] Furthermore, in the specific operation of step 3): Step 3.1) Data stream transmission and reception and electronic disk writing operations both use large data streams and DMA to copy data. The system is designed with dual-port RAM in a ring to buffer data. Step 3.2) When writing data to disk from the buffer, two thresholds are used to trigger the operation: time interval &T and data volume fixed length PACKET_LEN. For different subsystems, one of the two thresholds is selected as the trigger condition by comprehensive consideration.

[0032] In the specific operation of step 4): Step 4.1) The data statistics and recording function operates throughout the entire power-on process, covering three stages: before takeoff, during flight, and after landing. The focus of recording functions differs in each stage. See Table 2 for the specific content that needs to be statistically recorded. Step 4.2) The data statistics and recording function also includes corresponding fault handling functions, specifically including end device dynamic detection and exit, data write balancing, data cyclic overlay, disk space dynamic planning, and power failure abnormal handling.

[0033] Because disk space availability and the data content required for specific flight missions vary, this solution can not only flexibly store and record data accessed to the subnet, but also disconnect the recording function for data that is not needed in a timely manner, thus ensuring the effectiveness and reliability of data storage.

[0034] Taking a certain type of airborne computer network as an example, the large-capacity storage module SDM module in this type of aircraft is 1TBGB in size. It is interconnected with other subsystems through a fiber optic bus. According to the system configuration requirements, it mainly completes the storage and recording of network bus monitoring data (FC network bus monitoring data and GJB289A bus monitoring data, flight parameter information, central maintenance information, central maintenance fault information and flight management data).

[0035] Step 1: After the system powers on, it establishes link detection and requests for data logging functionality with the four subsystems via two types of FC short messages. See [link to details] for further information. Figure 1 The relevant procedures.

[0036] Step 2: Obtain the record information of each subsystem based on the data response request of the subsystem, dynamically plan the entire disk space, and allocate backup space to complete the data recording function in case of abnormal situations.

[0037] 1) Dynamic disk space design The physical space of the electronic disk is divided into the following four parts: logical disk C, logical disk D, logical disk E and logical disk F, as well as independent backup disk space. Their capacities are shown in Table 1.

[0038] Table 1 Dynamic Disk Space Allocation

[0039] Step 3: All recorded data in this system is received and processed via FC stream messages. 256MB of memory is allocated as a dual-port RAM buffer. After receiving data via FC stream messages, the front end first appends frame headers to mark different data types and buffers them. For GJB289A bus monitoring data and flight parameter information, since they are sent from the same subsystem and the data volume is relatively small, this system uses a 500ms periodic write operation. For the other four types of messages, which have larger amounts of data, a write operation is performed once the buffered data length for any of these message types reaches 1MB. After the five types of data write operations, the data is only committed to memory, not actually committed to disk. The system periodically uses a write balancing algorithm to ultimately commit all data to the local physical disk.

[0040] Step 4: The data capture and recording software monitors the entire system's operation from power-on to power-off, compiles the results, and performs corresponding fault handling actions based on the overall system operation status, as shown in Table 2.

[0041] Table 2 Statistical Results

[0042] Currently, the specific fault handling modes configured according to system requirements are: 1) Data cyclic coverage Due to the validity of disk space, deletion operations need to be performed when the disk space is full. To ensure the validity of data records, the specific execution time for disk space deletion is at two points: when the system is powered on and during operation. During power-on, deletion is performed according to a pre-set threshold to ensure that recording can begin at the start. At the same time, disk space is constantly monitored during data recording, and once the deletion conditions are met, the earliest stored data is deleted.

[0043] 2) Backup disk space writing Reserve backup disk space to record data. Data recording is the most important thing during flight. Once a subsystem needs to record data, it must ensure that the data is recorded normally. If the program detects that it cannot record data normally during operation, it will immediately start the backup disk space to ensure that the data is recorded in abnormal situations for subsequent troubleshooting.

[0044] 3) Subsystem dynamic monitoring and exit Design a general link detection mechanism so that the subsystem can start the data recording function at any time as long as it can access the system network according to the corresponding rules, and can also exit the network at any time when it does not need to record data to save system resource consumption.

[0045] In a specific embodiment of the present invention, a trusted storage and recording method based on an airborne network includes the following steps: S1. The network management function based on the airborne network obtains the real-time online status of all online sub-nodes, and sends a broadcast link request message to the online subsystem according to the node online status. The online subsystem that receives the broadcast link request message makes an autonomous decision and generates response request information and feeds back the response based on the current task requirements and resource allocation strategy. S2. Obtain the remaining storage space on the local disk, combine the response request information of the online subsystems to dynamically plan and allocate the corresponding directory structure and disk storage space for each online subsystem, and send the start data sending command to the online subsystems with allocated storage space; S3. Receive data from each subsystem and use a dual-port RAM ring buffer and DMA mechanism to achieve efficient transmission of large blocks of data. By setting two key parameters, namely the throughput threshold and the disk writing interval threshold, the hierarchical disk writing operation of large-capacity data is triggered to write the buffer data to the large-capacity electronic disk. S4. The system monitors in real time whether it receives data sent by the online subsystem. If the data reception is successful, the data is written to the pre-allocated directory structure and disk space. If the data reception fails, the system returns to step S1 to re-establish the connection. S5. Monitor the operation of the airborne network and collect statistics on the results, and take fault handling actions based on the statistics.

[0046] When monitoring and statistical results indicate that the disk space is full, corresponding deletion operations need to be performed. These operations are performed at two times: when the system is first powered on and during operation. During power-on, deletion is performed according to a pre-set threshold to ensure that recording can be started at the beginning. At the same time, during operation, disk space is constantly monitored, and once the deletion conditions are met, the earliest stored data is deleted.

[0047] Design a general link detection mechanism so that the subsystem can start the data recording function at any time as long as it can access the system network according to the corresponding rules, and can exit the network at any time when it does not need to record data.

[0048] The data is stored in the corresponding directory structure and disk space. Specifically, large-capacity data write operations are performed on the airborne network at time interval thresholds and data throughput thresholds to achieve load balancing and data integrity assurance of the storage system.
