Solution Overview
Problem
High voltage power transmission systems have a multitude of connections for different types of data communication, leading to complexity and inefficiency, with existing solutions not specifically addressing the need for reducing these connections.
Innovation Solution
A method and device that utilize a single point-to-point connection for transmitting data, incorporating a frame structure with distinct sections for measurement samples, field bus data, and synchronization data, allowing for efficient transmission and reception of data symbols using 8B/10B coding, thereby reducing the number of connections and enhancing synchronization.

1Reliability
If multiple separate connections are used for different data types (measurement samples, field bus data, synchronization data), then each data type can be transmitted reliably, but the number of connections increases system complexity
Solution Approach 1:
The patent combines multiple separate connections for measurement samples, field bus data, and synchronization data into a single point-to-point connection. A frame structure is implemented that multiplexes these different data types within one communication channel, reducing the number of physical connections while maintaining reliable transmission of each data type through dedicated frame sections.
Solution Approach 2:
The single point-to-point connection is designed to perform multiple functions by transmitting different data types (measurement samples, field bus data, synchronization data) within the same communication channel. The frame structure enables this universal connection to handle various data types through structured organization and synchronization mechanisms.
2Device complexity
If a single point-to-point connection is used for all data types, then the number of connections is reduced, but data synchronization and separation become more difficult
Solution Approach 1:
The communication frame is segmented into distinct sections for different data types (measurement samples, field bus data, synchronization data). This segmentation within the single connection allows easy identification and extraction of each data type through frame structure analysis, reducing the difficulty of detecting and separating data despite using only one connection.
Solution Approach 2:
Synchronization data acts as an intermediary mechanism within the frame structure, enabling the receiver to properly interpret and separate different data types transmitted over the single connection. The synchronization information facilitates correct data extraction and timing without requiring separate dedicated connections for each data type.
3Reliability
If traditional separate connections are used for each data type, then data transmission is reliable, but transmission speed and efficiency are reduced
Solution Approach 1:
Multiple data streams are merged into a single high-speed point-to-point connection, utilizing the full bandwidth of one channel to transmit all data types simultaneously through frame multiplexing. This approach achieves higher transmission speed compared to multiple separate connections while maintaining data integrity through structured framing and synchronization.
Data Source
AI summary
The invention concerns a method and first device (32) for transmitting data related to the control of a high voltage power transmission system as well as to a method and a second device (50) for receiving data related to such control. The first device provides (40) a frame of data including data symbols in a frame structure providing sections for data symbols containing measurement samples and field bus type of data, inserts (42) synchronization data into the frame in the form of control symbols distinctively separated from the data symbols and sends (44) the frame to the second device (50) in a point-to-point connection (34). The second device (50) receives (54) the frame, extracts (56) the synchronization data and processes (58) the frame after the extracting, for obtaining the data symbols. The synchronization data being inserted and extracted this way concerns synchronization of control activities performed by the second device.
