Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data transmission methods in the power industry, based on the ASN.1 standard, are inefficient in real-time data transmission due to the need for frequent analysis and encoding of data type and construction information, leading to increased data size and processing complexity, which cannot meet the requirements of rapid data exchange between numerous substations and power plants.
Innovation Solution
A data transmission method and system that encodes the type and construction information only during the initial transmission, allowing subsequent data transmissions to omit this information, using a data transmission terminal equipped with a language parser, encoder, and decoder to facilitate efficient data processing and reduce communication resources, employing the M language to define data construction and format, and utilizing static data construction preparation and dynamic libraries for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If type and construction information is transmitted with every data packet, then data can be properly parsed and decoded, but data transmission efficiency deteriorates due to increased data size and processing complexity
Solution Approach 1:
The patent applies preliminary action by establishing a data dictionary before actual data transmission begins. The data dictionary contains predefined type and construction information that both transmission and reception terminals use. This preliminary setup eliminates the need to repeatedly transmit and parse type information during data exchange, thereby improving transmission efficiency while maintaining reliable data parsing through the pre-established dictionary.
2Measurement precision
If type and construction information is analyzed and transmitted for each data item, then accurate data decoding is achieved, but processing time increases and communication resources are consumed
Solution Approach 1:
The patent implements universality by creating a data dictionary that serves multiple functions: it stores type information, construction characteristics, and decoding rules for various data formats. This universal dictionary structure allows the system to handle different data types efficiently without requiring separate analysis and processing for each data item, thus reducing processing time while maintaining accurate decoding through the comprehensive dictionary entries.
3Adaptability or versatility
If complex coding and decoding procedures are used to handle various data types, then data compatibility is improved, but transmission speed decreases
Solution Approach 1:
The patent applies preliminary action by pre-establishing a data dictionary that maps different data types to standardized representations before transmission occurs. This preliminary mapping allows the system to handle various data types compatibly while using efficient, standardized encoding during actual transmission, thereby maintaining high transmission speed without sacrificing adaptability to different data formats.

AI summary
A data transmission method includes: upon initial transmission of data, a data transmission terminal acquiring the type and construction information of the data, and encoding the type and construction information and the data for transmission to a data reception terminal, and the data reception terminal decoding the received type and construction information and data; and upon subsequent transmission of data, the data transmission terminal encoding the data for transmission to the data reception terminal, and the data reception terminal decoding the received data according to the type and construction information. According to the invention, at the data transmission terminal, it is unnecessary to make an analysis to acquire the type and construction information of the data in each transmission, to thereby dispense with a significant workload of data compilation, save communication resources and reduce the time for processing the data. Also, the data transmitted subsequently by the data transmission terminal does not include the type and construction information of the data, causing the transmitted data packets to be relatively small to thereby facilitate rapid and efficient transmission of the data.
