A field device communication method based on eib protocol

Abstract

The invention discloses a field equipment communication method based on a European installation bus (EIB) protocol. A corresponding protocol stack is created according to an EIB protocol standard to encapsulate and analyze transmission data layer by layer, namely the transmission data is encapsulated and analyzed by a physical layer, a link layer, a network layer, a transport layer, an application layer and a user layer, and relevant parameters are transmitted through the protocol stack by using a global data structure during communication. By the method, the application threshold of an EIB product in a domestic market is greatly lowered, the problem of technical 'bottleneck' of the application of the EIB product in the domestic market is solved, technical support is provided for domestic enterprises in the aspect of EIB application, and solid foundation is established for fully applying an EIB technology in the markets; and the practice cost of the EIB product can be greatly reduced, the level of intelligent identification and wisdom perception of the EIB product in the application field of intelligent lighting, intelligent home, wisdom communities and the like can be improved, and good economic benefit and social benefit can be achieved.

Description

technical field [0001] The invention relates to field bus and control technology, in particular to a field device communication method based on EIB protocol. Background technique [0002] At present, EIB bus technology, as a field bus standard with excellent performance, was designated as European standard, international standard and national standard in 1999, 2005 and 2007 respectively. The application of EIB bus products in the domestic market has entered the promotion and application stage from the introduction period. With the development of technologies such as intelligent buildings, comprehensive energy management, and Internet of Things smart perception, domestic EIB bus technology will usher in a blowout application period in the market. [0003] The communication design and implementation method based on the EIB protocol in the field equipment is the key technology for the promotion and application of the EIB bus technology. At present, there are two main solutions:...

AI Technical Summary

Problems solved by technology

[0005] 1. EIB packaging technology is mainly monopolized by large foreign manufacturers such as Siemens. Although there are many domestic scientific research institutes engaged in this field, most of them are in the stage of familiarization and understanding, with little progress and lack of general technological breakthroughs

2. Domestic companies generally lack strong technical support. The research and development of EIB bus products is mainly based on the BCU unit of Siemens and other manufacturers for OEM development. In fact, it is only the development of application modules.

3. On the one hand, the market potential of the application of the EIB protocol is huge. On the other hand, due to the lack of support for products with independent intellectual property rights, the application cost of EIB bus products remains high, which seriously restricts the promotion and application of EIB bus technology in China.
