本分布式小区智能网络模型采用符合现场总线(Fieldbus)要求 的CAN技术，以带CAN总线端口的主控机和单元控制器CAN端接口构成的 CAN网络层，下层为由带RS485端口的住户采集器和单元控制器RS485端 接口构成了RS485网络层，向上则利用PC机连接CAN网络层，作为智能 化小区管理中心，从而基本实现智能小区管理、控制、报警、信息采 集和自我检测的功能。 本文从智能小区、现场总线、CAN技术到“CAN+RS485”双底层网 络模型的软、硬件研究，较为详细的介绍了其设计、调试运行和期间 各种问题的解决。 -The Distributed Intelligent Network model district in line with Fieldbus (Fieldbus) requirements CAN technologies to bring CAN bus port主控机and cell controller CAN-side interface consisting of CAN network layer, the lower the grounds with RS485 port Household acquisition and cell controller interface RS485 client constitutes a RS485 network layer, up modem to connect to the PC using the CAN network layer, as the Intelligent Community Management Center in order to realize the basic intelligent community management, control, alarm, information collection and self-testing function. This article from the Intelligent Community, Fieldbus, CAN technology to

随着现在社会的发展，人们都避免不了要到某些城市去公干或其他的事情。一旦你对这个城市不熟悉，你的出门就会举步维艰。打的，对于一些因公出差的人来说算不了什么，但是对于旅游者或是个人来说就不是很好的选择。-now with the development of society, people should not have to avoid certain cities for business or other matters. Once you are not familiar with this city, you will be difficult to leave home. Fight, some on official business who is nothing, But tourists or individuals is not a good choice.
