Environment Monitoring System Based On Wireless Network And Internet

Environment monitoring system based on wireless network and Internet is a modern monitoring system which integrates modern wireless communication technology, the signal gathering technology and computer network technology. The modern monitoring system is not only consisted of independent instrument and apparatus. The network has become a new trend in the development of the measurement technology.In this paper a modern environment monitoring system is described and implementing schemes for the whole system is presented. The paper discusses the design method of the on-the-spot noxious gas monitoring instrument, the uplink of industrial data and the realization of industrial websites. With the implementation of real-time online monitoring network, users can browse the on-the-spot data in any place.The whole system is made up of two major parts. That is, the design of the software and hardware of the on-the-spot noxious gas monitoring instrument, the software design of the upper computer monitoring system. The on-the-spot noxious gas monitoring instrument focuses on the software and hardware design of gathering parameters and temperature of industrial field, setting parameters, storing data and manipulating wireless modem to set up wireless link.The software design of upper computer monitoring system includes two parts which are the data transfer server software and the design of industrial websites. These two parts of software are installed on the main server and web server separately. The data transfer server which is implemented with java language can offers a friendly human-machine interface for users. Server provides a set of functions, receiving the data, sending the order, long-distance setup, analyzing the data received and importing into the database etc.Industrial websites which is implemented with JSP are installed on web server, which enable the users to access to industrial websites. It offers many kinds way to data, such as the form, the curve, the histogram flow chart of site etc.Based on the research mentioned above, the environment monitoring system based on wireless network and Internet can meet the demand of modern environment monitoring and it also can offer a reference for the development and realization of the similar systems in the future.
