摘　　要：针对目前室内环境监控领域存在的环境信息采集能力薄弱、处理过程缺乏标准、硬件系统复杂等问题,基于Xilinx Zynq平台和IEEE 1451.2协议,设计了一个可对多种环境信息进行监控的系统.该系统主要包括智能变送器接口模块(smart transducer interface module,STIM)和网络适配应用处理器(network capable application processor,NCAP)模块.其中,STIM依据IEEE 1451.2协议实现环境信息的采集及其标准化;NCAP则利用受限应用协议(constrained application protocol,Co AP)实现系统的远程访问和控制.同时,通过设计基本资源、复合资源和规则资源3类资源,实现系统业务功能的统一描述和发布.经测试证明,该系统能够有效地实现对室内环境的远程监控,用户访问的响应时间较短,系统总功耗较低.In cmTent indoor environment monitoring field, there exist problems such as weakness of compatibility in collecting environmental information, standard deficiency of processing environmental information, and complexity of hardware system. To solve these problems, a system that can monitor muhiple environmental information and control indoor environment remotely was designed, based on Xilinx Zynq platfoml and IEEE 1451.2 protocol. The system mainly contained two module： smart transducer interface module （STIM） and network capable application processor （NCAP）. Between them, the collection and standardization of environmental information was realized by STIM, based on IEEE 1451.2 protocol. The remote access was realized and the system was controlled by NCAP based on the constrained application protocol （CoAP）. Three resources, containing basic resource, compound resource and rule resource were designed to guarantee the coherence between description and publication in system business function. System test resuhs show that the system can realize remote monitor and control indoor environments effectively with a faster response time to user＇s request, and a lower total power consumption.
