【摘要】：各个高校和企业的实验室作为国家科技创新战略的“桥头堡”和新技术的诞生地,伴随着国家和人民对高新科技大量不断的需求而日益涌现。无论是国家高校建设的还是民间企业建设的实验室,都是实施创新驱动发展战略、提高国家科技竞争优势的核心力量。然而在科技创新实验室大发展的同时,也总是出现各种本应避免的事故,造成不小的人员伤亡和财产损失。这使得与实验室配套的安全保障设施的建设变得尤为重要,其中包括对实验室气体环境中危险气体的监测。而大部分的危险气体都无色无味,使人不易察觉,这就需要智能的气体环境监测系统来保障环境的安全。目前,已有的一些实验室气体环境监测系统大多为配备落后管理系统的有线监测网络系统。这种系统安装布线杂乱,节点智能化程度低,维护性和扩展性差,而且查看数据以及管理系统都很困难。通过无线传感网络实现对气体环境的实时检测,辅以智能管理系统,再协同相应的报警排险系统的气体环境监测系统,必将成为企业安全生产创新应用的新方向。本文以智能实验室气体环境监测系统设计为研究对象,利用新型的物联网技术驱动整个系统的建设。依靠微软.NET平台设计了基于物联网相关的传感器技术、短距离无线通信技术和数据处理技术来完成本系统设计。在本监测系统的设计中,被监测的环境为实验室工作区域的气态环境,包括可燃、有毒气体的监测。其中,传感节点拥有数据采集、信息处理、无线传输等功能。本系统的上位机软件将对底层汇聚来的数据进行融合处理,并以友好的方式通过WPF(Windows Presentation Foundation)桌面应用展现在用户面前。如若出现危机情况,例如可燃、易爆或有毒气体出现泄露,本系统将在第一时间通知用户出现险情并提示险情区域,从而达到智能监测环境的目的。因此,本系统主要解决的任务包括对传感器节点数据的及时采集,以及为提高数据可读性而进行的数据处理和展示。
[Abstract]:All of the universities and enterprises as the birthplace of the laboratory of national science and technology innovation strategy of "bridgehead" and new technology, with the country and the people of technology unceasing demand and increasingly emerge. Both the construction of national universities and the construction of private enterprise's laboratory, is the implementation of innovation driven development strategy to enhance the core competitive advantage of power the national science and technology. However, in the development of science and technology innovation laboratory at the same time, it always appears all should avoid the accident caused no small casualties and property losses. This makes the construction of safety facilities and laboratory facilities has become particularly important, including monitoring of hazardous gases in the environment. The laboratory gas and hazardous gases most of the colorless and tasteless, make people difficult to detect, which requires the gas environment intelligent monitoring system to ensure environmental safety. At present, the existing Some laboratory gas environment monitoring system mostly cable monitoring network system with backward management system. This system wiring clutter, intelligent node, maintainability and scalability, and view data and management system are very difficult. The wireless sensor network to achieve real-time detection of gas environment, combined with intelligent management the system of environmental monitoring system, gas alarm system and the corresponding cooperation, will become the new direction of production safety innovation application of enterprise. With the intelligent gas monitoring system design laboratory environment as the research object, the construction of the whole system to drive the use of networking technology to new. Rely on Microsoft.NET platform is designed based on sensor networking technology related, short distance wireless communication technology and data processing technology to complete the design of the system. In the design of the monitoring system, was sent to prison Test environment for the laboratory work area of gaseous environment, including flammable, toxic gas. The sensor nodes have data acquisition, information processing, wireless transmission and other functions. The system of the PC software to integrate the data processing on the bottom of convergence, and in a friendly manner through WPF (Windows Presentation Foundation) desktop applications show in front of the user. If a crisis situation, such as flammable, explosive or toxic gas leak occurs, the system will be the first time to notify the user of danger and prompt the danger area, so as to achieve the purpose of intelligent monitoring of the environment. Therefore, this system is mainly to solve the task including the timely collection of sensor nodes and data. To improve the readability of data processing and data display.
