BICS (Building Intellectualized Control System) Based On Bus Mastering

Buildings make new demands to intellectualization. The BICS abroad have been dominating this market in China and world. They have their individual and close control protocols that are not compatible with each other, which seriously blocks the development of this industry. It is very necessary and feasible to develop BICS with our own independent intellectual property and brand.Catering to this demand and supported by bus master technology, BICS thus comes into being with full vigor.The world is seeking for compatibility among BICS from different countries and manufacturers. There are two ways, one is to compile a special protocol for the purpose of regulating the managing and controlling system, and the other is to adopt the present general network protocol.Research method: Spot bus mastering system and Lonworks bus mastering technology.Spot bus mastering system decentralizes its integrative control to the instruments at the spot. It cancels the DDC from DCS, and disperses measure, retrieve calculation and control to the spot instruments, hence actualizes the independence of spot instruments. A new structure of dispersive control system appears to be more predigested and reliable.The connection of the spot bus mastering system is very simple. A twisted pair can be connected to many devices. The newly added device could be connected to the nearest twisted pair. This saves cost and labor. A consumer could choose devices from different brand to integrate his system. He is not limited to any single brand; neither will there be problems like system integration protocol nor interface non-compatibility.The complete and mature bus master theory, the advanced hardware, full developing technology have offered very good conditions to the exploitation of BICS based on bus mastering. It could be developed with combination of the institute's research, direction of the government and the demand of the market.With the development of our modernization construction and increase of economy, lots of intellectualized buildings have been put up each year. Among the annual 8 billion Yuan domestic quotient, there will be a demand of 400 million Yuan if bus mastering system stands 5 percent. Supposing the traditional control systems hold 50% of the quotient, the bus master system will have another share of approximate 200 million Yuan. Therefore, the new bus mastering system has a very optimistic future.
