Data processing method and device of centralized station terminal access line loss acquisition module

Abstract

The invention discloses a data processing method and device for a centralized station terminal access line loss acquisition module. A data processing module sends a command message to the line loss acquisition module according to a polling period, receives a serial port message sent by the line loss acquisition module according to the command message, analyzes and processes the serial port message to obtain real-time electrical degree data contained in the serial port message, and writes the real-time electrical degree data into a shared memory and notifies other modules of the station terminal of a concurrent message. The other modules comprise a main module and / or a communication module; through a shared memory and a message mechanism, the main module, the communication module and the like can access data from the shared memory when needed, so that the data processing amount of the main module is reduced; and meanwhile, the problems of data sharing and cooperation among the modules when a plurality of software modules of the centralized DTU run at the same time are solved.

Description

technical field [0001] The invention relates to the technical field of distribution networks, in particular to a data processing method and device for a central station terminal access line loss acquisition module. Background technique [0002] The centralized station terminal (centralized DTU) requires the line loss measurement function, and the line loss measurement function usually needs to be realized by the supporting line loss acquisition module. The line loss acquisition module is used to collect the electrical data of each line interval. The line loss acquisition module is connected to the centralized DTU core unit (including the main module, communication module, etc.) through a serial port, and is realized by adding a data processing module to the DTU core unit. The line loss acquisition module and the main module perform data transmission. [0003] After the existing data processing module obtains the electrical data sent by the line loss acquisition module, it f...
