Embodiment Construction

[0018] The structural block diagram of the embodiment of the present invention is as figure 2 shown. The data memory stores the following four data:

[0019] (1) N1, single data item, 4-byte signed integer 0xAA998877, stored in the 4 bytes of address 0x0100, 0x0101, 0x0102, 0x0103 in high-endian order, that is, the 4 bytes store 0xAA, 0x99, 0x88, 0x77;

[0020] (2) N2, 2×3 2-dimensional signed integer array, N2[0][0]=0x0001, N2[0][1]=0x0002, N2[0][2]=0x0003, N2[1] [0]=0x0011, N2[1][1]=0x0012, N2[1][2]=0x0013, stored in the 12 bytes starting from address 0x0200 in low-endian order, namely: 0x01 , 0x00, 0x02, 0x00, 0x03, 0x00, 0x11, 0x00, 0x12, 0x00, 0x13, 0x00;

[0021] (3) N3, a single data item, the year, month, and day string "12 / 06 / 01" with a length of 8 bytes, stored in 8 bytes starting from 0x0300 in low-endian order, as follows: 0x31, 0x30, 0x2F, 0x36, 0x30, 0x2F, 0x32, 0x31;

[0022] (4) N4, a single data item, the time string "07:30:59" with a length of 8 bytes,...

Abstract

The invention relates to a data management system specific to communication access, and belongs to the technical field of information acquisition and data communication. The data management system is characterized by comprising a data storage for storing communication access data items, a configuration information table for storing data item attribute parameters, a query processor, a write-in controller and a reading controller. After write-in and reading commands of a communication access controller are received by the write-in controller and the reading controller, the data item attribute parameters in the configuration information table are queried through the query processor, and then processes of writing communication data in the data storage, reading the data from the data storage and writing the data in a sending data buffer according to byte order states are completed. The data items can be added, deleted or modified only needing to modify the configure information table without modifying other parts, and information maintenance is simple. Besides, since compatible processing of byte order is achieved, and the system is clear in structural, migration and application are facilitated.

Description

technical field [0001] The invention relates to a data management system for communication access, belonging to the technical fields of information collection and data communication. Background technique [0002] In the fields of electricity, machinery, finance, smart home appliances, etc., with the improvement of the level of intelligent automation, more and more data information is collected through various sensors, processing algorithms, and user interaction platforms, and these data need to pass some communication way to achieve remote access. Therefore, after the field device collects the data information, it needs to effectively organize and manage the information so as to realize communication access. For example, the Electric Power Industry Standards of the People's Republic of China "DLT645-1997 Communication Protocol for Multi-Function Energy Meter" and "DLT645-2007 Communication Protocol for Multi-Function Energy Meter" put forward hundreds of parameters for elec...
