Method for transmitting data records

Abstract

The invention relates to a method for transmitting data records (D1...n) between a central communication device (Z) and any number of terminals (X1...n). At least one data co-ordination device (E) ensuring the data transmission between the central communication device (Z) and the terminals (X1...n) is provided, said data co-ordination device receiving or forwarding data records (D1...n) transmitted over the first data transmission section (A) between the data co-ordination device (E) and the terminals (X1...n), and a second data transmission section (B) between the data co-ordination device (E) and the central communication device (Z), the first data transmission section (A) being part of a low-voltage network (PLC). According to the invention, priority steps (P1...n) are defined for the data records (D1...n) to be transmitted over the first data transmission section (A). A reference time span (T) is defined for the transmission of the data records (D1...n), and a determinable part (T1...n) of the reference time span (T), in which the first data transmission section (A) is provided for the transmission of data records (D1...n) corresponding to each priority step (P1...n), is associated with the respective priority step (P1...n).

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for the transmission of data sets between a central communication device and any number of terminal devices, wherein at least one intermediary between the central communication device and the terminal devices is provided A data coordinating device for data transmission between, the data coordinating device receiving and forwarding the first data transmission segment between the data coordinating device and the terminal device and between the data coordinating device and the central communication device The data sets transmitted on the second data transmission section of the , wherein the first data transmission section is part of a low-voltage network (PLC), and the invention also relates to a system according to claim 16 for implementing the inventive method. Background technique [0002] Power line communication systems (PLC) use the low-voltage power grid existing for power suppl...

AI Technical Summary

Problems solved by technology

[0011] In addition to insufficient stability, known low-voltage communication systems also have a lack of flexibility in transmitting different data sets and cause multiple delays in data transmission

In many cases, commands and data records from the central communication network arrive at the data coordination device faster than these data and commands can be forwarded to the corresponding terminal device, because the data record request from the terminal device according to the standard (Datensatzerhebung), the first data segment is blocked
