Abstract

The invention discloses a power distribution and utilization data access method and device. The method comprises the steps of obtaining a data access request sent by a first container through a bus based on an MQTT message protocol; forwarding data to a corresponding data interface; the data interface responding to the data access request, performing corresponding data processing based on a presetdata access rule, and caching the processed data in a memory; storing the processed data cached in the memory in a file and a database; and returning a processing result of the data processing to thebus so as to enable the bus to forward the processing result to the first container. According to the power distribution and utilization data access method and device, cross-container access of the data is realized through a bus based on an MQTT message protocol; and meanwhile, a memory access and file access mode is used as a real-time data access mode for data access, and a database storage mode is adopted for a historical data access mode, so that the data access efficiency problem and the data recovery problem after equipment power failure are solved.

Description

technical field [0001] The present invention relates to the field of smart grids, and more specifically relates to a method and device for accessing power distribution data. Background technique [0002] With the rapid development of marketing and power distribution Internet of Things, the amount of data that needs to be monitored by the power distribution master station has increased sharply, so edge computing capabilities need to be rapidly improved. In order to ensure the edge computing capability of the distribution transformer station area, that is, the computing capability of the intelligent terminal in the station area, it is necessary to further optimize and improve the local access capability of distribution data. [0003] A currently commonly used power distribution data access scheme uses a large point table (a form of configuration file mapping relationship-pointed memory access, which evolved from the use of the IEC104 protocol to access the power distribution m...
