Research And Application On LonWorks FieldBus In Security System Of Intelligent Community

The security reform of Xi'an Maple Leaf New Urban Area highlights the urgent needs of the intelligence communities in our country, and also exposed all the problems of Intelligent Community at present, particularly the traditional residential development control system, which is considered to be the most direct restriction factor for the Intelligent Community development. To solve this problem, this paper focuses on the LonWorks which has been widely used aboard and to apply it to the construction of Chinese intelligent communities.By analyzing the prospect and trend of the Fieldbus of Intelligent Community this thesis demonstrates the superiority of using LonWorks to construct intelligent communities at present and in the future. Combining the characteristics of LonWorks, we explain how the Intelligent Community Security Subsystem is to be achieved and be effective. Especially we illustrate it with the combination of the specific security cell transformation project.This paper first had researched the development of Fieldbus system and the Intelligent Community system. The LonWorks technology is introduced mainly from both hardware and software aspects. And then a brief description of each subsystem of the security system is followed. Chapter four is the core of this thesis, first of all, based on the Security reformation project of Xi'an Maple Leaf New Urban Residential Area, a LonWorks network design is conducted for the community security system, and for each subsystem, especially for closed circuit monitoring system detailed design and configuration selection is also conducted, and then focusing on family-based security subsystem, the intelligent node is designed, with the hardware and software of the node to be designed respectively. For the hardware, mainly the Neuron Chip 10 port, A/D converter, transceiver, selection and circuit design of the device is to be designed. For the software, we mainly apply NeuronC language to program the data collection process in order to achieve communication purposes.Finally, we use WinCC configuration software for residents of information and family security node status monitoring interface design, convenient for residential property manager within each household to query and management of the security situation, to protect the safety of the households.
