Development Of Monitoring Platform For Intelligent Building Based On Decentralized Network

The informationization and intellectualization of building is the trend of contemporary architectural development.With the development of modern computer network communication and electronic technology,a large number of intelligent buildings with automatic control network have sprung up.However,the intelligentized effect of building in actual operation has not achieved the expected goal and causes a series of engineering bottlenecks.Investigate its reason,it is difficult for the intelligent building system architecture to meet the requirements of intelligent building'rapid development.Therefore,this design develope a monitoring platform for intelligent building based on the decentralized network.The specific work of this paper is as follows:First of all,this paper summarizes the current research status of the monitoring platform for intelligent buildings and the decentralized network.Research intelligent building system architecture,working mechanism,the communication protocol and intelligent nodes of the decentralized network.The overall architecture of the intelligent building monitoring platform based on the decentralized network is designed.The whole monitoring platform is composed of monitoring software,intelligent node of the decentralized network,and the underlying equipment terminals.Complete the information collection and control function of the underlying equipment,and realize the decentralized network management of platform.Secondly,in order to solve the communication problem between the underlying device and intelligent node of the decentralized network,an embedded gateway was developed.The gateway adopts ARM as the main control chip,the RS485 interface and 433 MHz wireless interface circuit of the gateway increase the capacity of external equipment.The underlying device data collected through the gateway will eventually be uploaded to the decentralized network.The data conversion protocol program is designed and the communication function of the intelligent node and gateway is tested.Secondly,in order to realize the real-time data acquisition for the power outlet of the decentralized network,the intelligent socket is developed.The power circuit and the power acquisition circuit of the intelligent socket are designed.The CC430 chip is used as the processor and wireless communication module,and the software design of the intelligent socket is completed.Finally,the collected data is transmitted to the gateway via wireless module.Finally,a monitoring experiment platform for intelligent building based on the decentralized network are set up in the laboratory.The embedded gateway and the intelligent socket and its communication function are tested,and the actual running parameters are uploaded to intelligent node of the decentralized network,and the visualization of the data is realized through the monitoring software.The system realizes the management for intelligent building through a new network architecture,and solves the practical problems such as the lack of data sharing among the various systems of intelligent building and the difficulty of system configuration.The decentralized network architecture is flexible,it has the potential advantages to improve the operation management level and save energy consumption.Therefore,it is of practical significance to research and develop a intelligent building platform based on the decentralized network.
