Problems solved by technology
This processing method has two shortcomings. One is that when a one-dimensional or two-dimensional array is used to store data, the array needs to be maintained at the code level when the data type changes; the other is that the data stored in the array can only represent data Its own value or a simple description of some meanings

Embodiment Construction
[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will further describe in detail the embodiments of the present invention in conjunction with the accompanying drawings.
[0024] The scheme adopted by the present invention is to divide it into 6 parts in a continuous storage area, see the attached figure 2 . in:
[0025] Number of tables: the number of tables stored in the header address information area.
[0026] Table head address information area: This area stores the head address of each table in the original data area and data description area. During the data access process, the positioning of the table (X positioning) is realized.
[0027] Number of codes: the number of mapping tables in the data code and X-Y mapping area.
[0028] Data code and X-Y mapping area: This area stores the corresponding relationship between data code and data table number and serial number.
[0029] Received raw data a...

The invention discloses a data exchange method for a real-time data processing system, which comprises the following steps of: compiling a corresponding data dictionary; in a continuous storage area,defining a data structure, and estimating the data volume required to be processed when the data structure is used according to the data dictionary; according to the received original data, carrying out searching according to a data structure; and after the head address corresponding to the original data is found, performing conversion according to the data type defined in the data dictionary to obtain an actual value of the data. In real-time data processing, processed data and related definitions of the data can be completely stored in the data structure by adopting the data structure. By using the data access method provided by the structure, the software modification workload caused by frequent change of data exchange formats or contents can be reduced, and the efficiency of data processing, exchange and use is improved. Meanwhile, the structure can be shared in a memory sharing mode through a computer, and real-time data exchange between processes is achieved.
Description
technical field [0001] The invention relates to a data structure and a data exchange method for data exchange of multiple two-dimensional tables in a real-time data processing system. Background technique [0002] In some data processing fields, data is often classified and processed in the form of two-dimensional tables. For example, a certain type of data is determined by X-Y, X is the table number, and Y is the number of data in the table. In data processing, two-dimensional arrays or a continuous memory are generally used to store real-time data. This processing method has two shortcomings. One is that when a one-dimensional or two-dimensional array is used to store data, the array needs to be maintained at the code level when the data type changes; the other is that the data stored in the array can only represent data Its own value or a simple description of some meanings. Contents of the invention [0003] In order to solve some data exchange problems in real-time ...
