Embodiment
[0021] The method for defining the unstructured data format in the present invention will be described in further detail below with reference to examples.
[0022] figure 1 Describe the characteristics of a hierarchically structured message block. A message block can contain several semaphores, and each semaphore contains several data bit fields. The data bit field is the basic unit that carries the definition of entity data.
[0023] figure 2 Example of a network data communication structure, which contains 2 original message blocks, each message block contains 3 semaphores, the semaphore contains several data bit fields, and the data bit field information load contains the basic data type and application data type , data resolution and other configuration information.
[0024] Step 1: According to the original message block and the contained specific content, expand layer by layer until the smallest data unit used to describe the data field. The outermost layer is the me...

The invention belongs to the data management category, and provides an airborne-network-oriented unstructured data format definition method. The method comprises the following steps: the step one: according to the airborne network data general format definition mode, expanding to the minimum data unit, namely the data field layer by layer, wherein each expanded data field corresponds to one item of the configured information; the step two: generating the data field description information through the original data structure; the step three: using the data field description information set generated in the step two as the configuration information applied and used for the upper layer, repeatedly executing the step two according to the expanded original data field sequence, generating the description information of each data field item by item, and recording in the configuration information orderly; and the step four: summarizing the generated configuration information items, configuring the mutual independence between the items, only keeping the sequence depending feature, and generating the binary or textuality unstructured data format configuration files according to the needs.
Description
technical field [0001] The invention belongs to the category of data management and relates to an airborne network-oriented unstructured data format definition method. Background technique [0002] In the definition of the general format of airborne network data, the message block is used as the basic unit of network message transmission. The data structure in the message block is described in a hierarchical structure. A message block can contain several semaphores, and each semaphore contains several data Bit field, data The bit field is the basic unit that carries the definition of entity data. The configuration information of the message block data structure is generally represented by a structured configuration file, such as XML format. When the application software uses the structured configuration file, it needs to include a relatively complex structured information analysis module, such as an XML parser corresponding to the XML format. This type of configuration dat...
