Embodiment Construction

[0057] The core of the present invention is to divide the link between the bus node devices into different data type links, and the different data type links between the bus node devices are modulated data transmission in the bus processing time slot according to different modulation methods, thereby avoiding The mutual influence of data transmission when multiple types of data are transmitted between bus node devices, and improves transmission efficiency, simplifies network deployment, and further satisfies data transmission needs, which is particularly suitable for home applications, as detailed below.

[0058] The bus communication system provided by the present invention includes a data bus carrying data transmission; and a plurality of bus node devices connected through the data bus. The bus node devices include links of different data types. The different data types between the links according to the corresponding different modulation methods in its bus processing time slot ...

Abstract

The invention discloses a bus communication system, including: the data bus carrying the data transfer; multiple bus node devices connected by the bus, the link between the bus node devices which can modulate different data types in the processing time slot of the corresponding bus via different modulation modes. In addition, the invention also discloses one corresponding data link establishment and data transfer method in the bus communication system. The invention can avoid the mutual influences when multiple types of data are transferred between the bus devices, can improve the transfer efficiency, simplify the network deployment, and further meet the requirement of the data transfer, so it is very applicable to the power carrier system within a small range, especially the home power carrier system.

Description

Technical field [0001] The invention relates to a bus communication technology, in particular to a bus communication system, a data link establishment and data transmission method. Background technique [0002] At present, the application of the bus is very extensive, usually, the bus is defined as a set of signal lines. These lines are the public channels between the plug-ins of the system (or between the internal chips of the plug-ins) and between the systems to transmit prescribed information, sometimes also called data highways, through which various data and commands can be transmitted to their respective destinations. Figure 1 shows a schematic diagram of a bus communication system, which mainly includes a data bus and multiple bus node devices connected via the bus. [0003] On the other hand, with the development of home networks, from the perspective of applications, a home network should have the following characteristics: ease of use, compatibility, and robustness. Fro...
