Abstract
Description
Technical Field
[0001] This application relates to the field of avionics system data acquisition technology, and more specifically, to an airborne 1394 bus data acquisition method, device, storage medium, and electronic device. Background Technology
[0002] Traditional 1394 bus data acquisition units typically employ a static, complete acquisition method, which captures all data on the bus indiscriminately. This method primarily includes the comprehensive acquisition of asynchronous and isochronous transmission data without real-time assessment of the data's validity or relevance.
[0003] In 1394 bus communication, there are numerous different types of management and control messages, such as bus reset identifiers, selfID packets, loop start packets, and PHY packets. Traditional acquisition methods indiscriminately collect all of these data, leading to the following prominent problems: High proportion of invalid data: Bus communication contains a large number of management and control messages that are irrelevant to specific applications. These messages have limited value for subsequent data analysis, but consume a lot of acquisition resources.
[0004] Waste of storage resources: Storage resources of airborne systems are extremely valuable. Static complete data acquisition will quickly consume limited storage space and reduce the continuous working time of the data acquisition system.
[0005] Low analysis and processing efficiency: A large amount of invalid data will increase the burden on subsequent data processing units, requiring stronger computing power to extract useful information from massive amounts of data, thus reducing the real-time performance of the entire system. Summary of the Invention
[0006] The embodiments of this application provide an airborne 1394 bus data acquisition method, device, storage medium, and electronic device to solve the problems of traditional acquisition methods that can only statically and completely acquire bus data, resulting in a large amount of invalid data and wasting subsequent storage resources and analysis and processing computing power.

[0027] The following detailed description of some embodiments of this application will be provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0028] See Figure 1 The diagram shows a flowchart of an airborne 1394 bus data acquisition method according to an embodiment of this application.
[0029] like Figure 1As shown, an airborne 1394 bus data acquisition method is illustrated, which specifically includes steps S100 to S400.
[0030] It should be noted that in this embodiment, the method is implemented based on FPGA, where the FPGA is responsible for dynamically parsing the configuration table content, generating filtering rules, acquisition methods, and controlling the data flow.
[0031] The control logic is as follows: The host computer loads the configuration table, including filtering rules and parameter extraction rules, into the FPGA via the bridge bus.
[0032] The FPGA filters irrelevant data according to filtering rules, collects only target data to the parameter extraction unit, extracts valid data according to the parameter extraction rules, and finally uploads it to the host computer according to the bridge bus unit transmission rules.
[0033] For details, please refer to Figure 1 Step S100: Acquire initial data based on the airborne 1394 bus; Step S200: Dynamically load filtering rules and parameter extraction rules; Step S300: Filter the initial data based on the filtering rules to obtain the target data; Step S400: Extract valid data from the target data based on the parameter extraction rules.
[0034] In some feasible embodiments, based on the foregoing scheme, the step of extracting valid data from the target data based on the parameter extraction rules includes: Obtain the correspondence between cache numbers and parameters to be extracted from the parameter extraction rules; Based on the correspondence, relevant parameter data is extracted from the target data as the valid data, and cached according to the cache number.
[0035] In some feasible embodiments, based on the foregoing scheme, the following further applies: Valid data in the cache is forwarded sequentially according to the bridging interface order.
[0036] Based on the same inventive concept, this application also provides an airborne 1394 bus data acquisition device.
[0037] like Figure 2 As shown, the device includes: The 1394 bus data receiving unit is used to receive initial data; The 1394 bus data filtering unit is used to filter the initial data according to the filtering rules to obtain the target data; The parameter extraction unit is used to extract valid data from the target data according to the parameter extraction rules.
[0038] In some feasible embodiments, based on the aforementioned scheme, the 1394 bus data filtering unit is connected to a filtering rule storage unit for storing the filtering rules.
[0039] In some feasible embodiments, based on the foregoing scheme, the parameter extraction unit includes: The parameter extraction rule storage sub-unit is used to store parameter rules; The cache number management subunit is used to obtain the correspondence between cache numbers and parameters to be extracted from the parameter rules. The parameter extraction subunit is used to extract relevant parameter data from the target data based on the correspondence between the cache number and the parameters to be extracted, and use it as valid data. The parameter cache subunit is used to cache valid data based on the cache number.
[0040] In some feasible embodiments, based on the foregoing scheme, the following further applies: The bridging unit is used to forward cached valid data in the order of the bridging interface.
[0041] refer to Figure 2 The working process of this device is as follows: After the 1394 bus data receiving unit collects and receives data, it forwards the data to the 1394 bus data filtering unit. The 1394 bus data filtering unit extracts the filtering rules from the filtering rule storage unit, filters invalid data according to the filtering rules, and forwards the valid data to the cache number management subunit.
[0042] The cache number management subunit obtains the correspondence between cache numbers and parameters to be extracted from the parameter extraction rule storage subunit, and forwards the correspondence to the parameter extraction subunit.
[0043] The parameter extraction subunit extracts the parameters from the data according to the correspondence between the cache number and the parameters, and forwards the parameters to the parameter cache subunit according to the cache number.
[0044] The parameter cache subunit forwards the extracted parameter data according to the timing sequence of the bridging unit interface.
[0045] In summary, this technical solution has the following advantages: 1. By dynamically loading filtering rules and parameter extraction rules, effective data on the 1394 bus is collected in a targeted manner; effective data is collected either synchronously or asynchronously. 2. The collected 1394 data is sent to the host computer for subsequent storage or processing via the Ethernet standard protocol, which is highly efficient. 3. Data acquisition and configuration parsing are implemented using hardware HDL language, supporting FPGA or tape-out, with high compatibility.
