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

1、 生产者―消费者问题是一种同步问题的抽象描述。 2、 计算机系统中的每个进程都可以消费或生产某类资源。当系统中某一进程使用某一资源时，可以看作是消耗，且该进程称为消费者。 3、 而当某个进程释放资源时，则它就相当一个生产者 -one, producer-consumer problem is a problem of synchronization of the abstract description. 2, the computer systems of each process can consumption or production of certain resources. When a process system using a resource, can be seen as expendable, and the process known as consumers. 3, and when a process to release resources, then it is a producer
