WSN论文：Profibus-DP与WSN的集成研究 【中文摘要】无线传感器网络是近年来工业控制领域的一大研究热点,其所具有的低能耗、低成本、高灵活性等特点,能很好弥补有线网络的不足之处。随着工业控制自动化程度不断提高、控制规模不断加大,在工业控制中引入无线网络已经成为一种趋势。因此,本文以无线传感器网络(WSN)和Profibus-DP现场总线为研究对象,进行两者的集成研究和应用实践。本文首先分析了无线传感器网络和现场总线技术的发展概况,描述了将无线传感器网络与现场总线网络集成的必要性。通过对系统的应用需求分析,提出了一种通过网关设备实现两种网络集成的技术思想,并给出了网关的设计方案。然后,本文按照以上提出的设计方案,讨论了网关硬件平台的设计和制作,探讨了适用于网关的软件设计过程。其中,网关的硬件设计包括：WSN模块电路、电源系统电路、Profibus-DP协议实现模块电路、外围接口电路等；网关协议转换的相关软件设计包括：WSN组网程序设计、WSN模块与Profibus-DP协议模块通信程序设计等。最后,针对以上设计的网关,搭建了网关测试系统,对网关的性能进行测试,结果表明,网关能够很好地工作,完成无线传感器网络和Profibus-DP网络的集成。在此基础上,网关还在某污水处理厂上进行了工程试用,完成原有控制网络之上新增点的无线测控,满足了工业现场应用要求。 【英文摘要】Wireless Sensor Network is one of the hot Industrial control technology in recent years, with the performance of low energy consumption, low cost, high flexibility, it can well compensate for the inadequancies of cable connection. At the same time, with industrial automation control development, it has become a trend to put Wireless Network into the Industrial automation control. In this paper, the research will focus on the Integration between Wireless Sensor Network (WSN) and Profibus-DP Fieldbus to realize seamless connection.This paper first states the development of Wireless Sensor Network and Fieldbus technology, the necessary of integration between this two network is proposed. Then, through the system requirements analysis, propose to design a gateway to get the integration between them and give the design scheme.Then, this paper get the work in accordance with the design scheme. It elaborate hardware platform and software design of the gateway. Hardware platform design of the Gateway contains WSN module, power supply system, Fieldbus protocol realize module, various peripheral interface circuit, etc. The software design contains WSN networking program design, communication between WSN module and the protocol realize module, etc.At last, build a gateway test system to test the performance of the gateway. From the results of the test, the gateway works very well. Base on thi
