Embodiment Construction

[0021] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The invention provides a distribution network FTU fixed-point file management method and device, which establishes a data area and a temporary file area in the memory, and stores the fixed-point data in the data area; when the fixed-point data needs to be uploaded, search in the data area The fixed-point data and the found fixed-point data are format-converted and stored in the fixed-point file in the temporary file area, and the fixed-point file is uploaded through the temporary file area.

[0023] method embodiment

[0024] Specifically, taking the fixed-point data storage and upload process within one day, the fixed-point file is an xml format file, and the storage is FLASH as an example, the FTU fixed-point file management method of the distribution network of the present invention is introduced. It should be noted here that the des...

Abstract

The invention relates to a distribution network FTU fixed-point file management method and device, belonging to the technical field of electric power engineering. Establish a data area and a temporary file area in the memory, and store the fixed-point data in the data area; when the fixed-point data needs to be uploaded, search for the fixed-point data in the data area, convert the found fixed-point data to the format, and store to the fixed-point file in the temporary file area, and upload the fixed-point file through the temporary file area. By storing only the required dynamic data, the disk space occupancy rate is effectively reduced; and the xml model operation, which consumes very memory resources, is converted into a direct operation on the memory, and the storage and management of fixed-point data is realized with minimal memory overhead. On the premise of high performance, the complexity and resource consumption of file management are reduced, and the product cost is effectively reduced.

Description

technical field [0001] The invention relates to a distribution network FTU fixed-point file management method and device, and belongs to the technical field of electric power engineering. Background technique [0002] FTU is Feeder Terminal Unit, feeder terminal device. It has the functions of remote control, remote signaling, and fault detection, and communicates with the main station of distribution automation to provide the operation status of the distribution system and various parameters, that is, the information required for monitoring and control. In order to facilitate the analysis of the master station, fixed-point data and other data, such as fixed-point data, SOE data, remote control data, reverse electric energy frozen value data, log data, extreme value data, daily frozen electric energy data, etc., are in the format of xml files Send it to the main station. FTU is an embedded, low-power, and low-cost device. Storage resources, especially memory resources, are...
