Research And Optimization Of Intelligent Building Automation Control System

In this paper, based on the advanced intelligent building control system, from thealgorithm and the priority of the control system to optimize the system, on theresponse time and made a big improvement on stability.Paper first describes the development and recent situation of BAS system BAS from alarge number of data in the system of the core technology is based on the fieldbustechnology, then classify the network protocol of fieldbus technology, finally draw aconclusion that, across the protocol layer and compatibility with the highest networkprotocol are two LonWorks and BACnet, so this article has decided to adopt theLonWorks and BACnet interconnection model to complete the optimization ofnetwork protocol, to speed up system response.The second chapter analyses in detail the logic diagram of BAS system, and byimproving the design of the logic diagram, and realized the optimization of controllinks, based on the DDC controller hardware, realizes the graphical interface control,from the handling and feedback ascend in the perfection of the system, and thehighest utilization rate in BAS system three subsystems interconnection model test,respectively is a complex surrounding cross-border system and patrollingmanagement system and building the emergency alarm system, interconnection modelis theoretically feasible conclusions finally.The third chapter mainly interconnection model implementation and simulation, andthe realization of the BACnet as LonWorks way is relatively uniform, just use level isdifferent, so this chapter puts forward the LonWorks optimization scheme based onNeuron chip neurons, completes the communication protocol from the hardwareoptimization, then adjusted the BACnet protocol in the algorithm, PID algorithm is proposed based on BACnet development, finally through the simulation, thetechniques you can use the network nodes and get greatly optimized.The fourth chapter is the core of this article, first, through the first three chapter ofconclusion LonWorks-BACnet interconnection model is established, and then usethe DDC controller and Neuron chip as a hardware platform of interconnection model,finally through a Neuron C program optimization, complete process simulation, theconclusion consistent with the expected.Finally, the paper get the conclusion and implementation of function are as follows:based on the performance of original system, greatly improves the response speed andthe stability of the operation, in case of emergency, the BAS system processing speedmore promptly, from the perspective of production costs, design more human basedon neuron chip and relatively low cost, the most important thing is to put forward afeasible network node compatibility mode, for the unification of BAS systeminternational standard put forward a feasible scheme.
