Direct interface method for Loytec module bus and high speed intelligent unified bus

Abstract

The invention discloses a direct interface method for a Loytec module bus and a high-speed intelligent unified bus, which is used for solving the technical problem that the conventional Loytec module bus cannot directly access the high-speed intelligent unified bus. The technical scheme comprises the following steps of: realizing high-speed serial-parallel conversion of high-speed intelligent unified bus data by high-speed serial-parallel conversion; configuring a high-speed intelligent unified bus protocol by using a low-speed logic device; caching data by using a high-speed double-port static random access memory (SRAM); intelligently switching a read-write clock of the SRAM by using a high-speed monitoring unit; and implementing an interface among a LonWorks bus of a Loytec module, Ethernet and a high-speed intelligent bus so as to complete interconnection of the Loytec module with the high-speed intelligent unified bus. Meanwhile, flexible interconnection of the Loytec module bus with other buses is implemented, the quantity of interconnected bus media in a system is reduced, and the power consumption of the system is lowered.

Description

technical field [0001] The invention relates to a bus interface method, in particular to a direct interface method between a Loytec module bus and a high-speed intelligent unified bus. Background technique [0002] The well-known Loytec module integrates LonWorks bus and Ethernet bus interface, so that the field-level data based on LonWorks can be transmitted to the management-level integrated control system in real time through Ethernet, so as to make correct decisions and obtain better control performance. The Loytec system is designed based on the building automation system, which can facilitate the distributed management of field level, automation level and management level. However, the Ethernet integrated in the Loytec system belongs to 10Mbps to 100Mbps adaptive Ethernet, which is quite different from the high-speed 10 Gigabit speed, so the maximum number of nodes supported by the Loytec system is very limited. However, the development of electronic system integratio...
