Research And Application Of Monitoring And Control System Based On Internet Of Things

With the continuous progress of the information process, a variety of emerging information technology continues to produce, develop and apply. These emerging technologies impact on traditional business models and production methods. In the third industrial revolution and the information technology and industrialization of the background, China’s emerging information technology is changing the way modern industrial production, but also by its growing demand is driving the development of its own technology, research and integration of more innovative technology, China from "Made in China" to "Chinese wisdom made "another step toward the transformation of intelligent leap.Chemical Industrial Park in the growth of local economic and social development at the same time, because of its industrial nature of the relationship between the local environment and personnel safety has caused security risks. How to strengthen the management of the source of risk is the most important content of enterprise security management. In recent decades,from time to time there will be a variety of security incidents in the park. If we do not strengthen the management of risk sources, the result is not only directly related to each park employees of the personnel security, but also related to problem of the development of the whole enterprise.Chemical parks tend to focus a lot of accumulation of dangerous chemicals and raw materials, if the surrounding environment changes, an explosion may occur. The park also stores all kinds of toxic gases, once the leak occurs, it is likely to occur casualties. How to reduce these safety accidents, as far as possible in advance of the accident prediction, after the accident can quickly and accurately respond to the decision-making and implementation of the rescue plan, is the urgent problem for the enterprise to seek solutions. Therefore, the system based on networking design, is the use of Internet of things to changes in the environment overall perception. According to the perception of the data mining analysis to security accidents of impending anticipation, the accident only in the initial stage. In addition to the improvement of the emergency command system, the intelligent detection environment can be largely completed, and the corresponding warning. Smart chemical plant to achieve a blueprint for a better.In the background of the integration of the two initiative, how to effectively obtain the basic environment information, how can in the chemical industry park of data for real-time transmission and intelligent application.The related technology of Internet of things is being paid more and more attention by enterprises and society because of these characteristics.IOT comprehensive coverage of park environment in depth sensing environmental parameters, accurately grasp the park environmental risk source state information and change the information and reduce to the environment to determine the risk of uncertainty, the implementation of more effective risk early warning and timely processing of preventive measures. Thereby avoiding and reducing environmental risk rate. The environmental monitoring system based on Internet of things technology and its application to chemical industry park, real-time environmental monitoring, in the process of environmental monitoring and realized the whole system of cable and wireless the effective combination of, more real-time, fast and easy to control.In the environmental monitoring and emergency response system, not only to fully consider the perfect design of system function, and combined with the actual environmental conditions and balance the cost of various factors, in order to establish a low cost, high reliability and high efficiency of chemical industrial park environmental emergency monitoring system; to provide appropriate and effective information through effective against the uncertainty risk and effective early warning, real-time information feedback of pollutants in excess of the information, in the emergency response process to achieve the source of risk concentration range, quantitative analysis change trend and the health risk of visualization, provide effective operational support and information command decision support.The emergency environmental monitoring system based on Internet of things in general to carry out research work from the following design:(1) The first of a practical chemical industry park started investigation of the status of environment monitoring and early warning and emergency system, process description, status description, the target system, gap analysis and suggestions for improvement 5 steps of demand analysis, after detailed analysis have propose solutions and subsequent functional design to achieve the targeted.(2) Design of chemical industrial park environmental monitoring wireless sensor network, combined with the actual requirements of environmental monitoring is proposed based on location and remaining energy of centralized clustering protocol to ensure the accuracy of the data acquisition, construction of environmental monitoring system of data base.(3) The design of emergency environmental monitoring system and database. The function of design according to the demand, this system is mainly composed of two parts of the emergency command subsystem, comprehensive environmental management. Environment comprehensive management subsystem includes the risk management, the hidden danger management, the accident/incident management, the environmental protection management. Emergency command subsystem includes assistant decision support system, accident consequence simulation and regional quantitative risk assessment subsystem, video surveillance management system, and meteorological parameter monitoring subsystem. The system database design spatial database and safety production database, by spatial database combined with the actual data for the realization of the interface visualization, expression is more intuitive, easy to accept. Production safety database mainly stores basic information on hazardous chemicals and environmental monitoring and early warning data.(4) Design and implementation of the system. This paper introduces the idea of the system realization from three aspects, which are the construction of the system infrastructure, the real-time data transmission and the software design.In this paper, for the expansion of the IOT technology in the actual needs of the Internet, and explore IOT core technology, relying on third end frame technique: induction remote sensing, the server and the application. Design and implement a network environment monitoring system based on B/S architecture.The design goal of the system is mainly to meet the enterprise demand for growing things, and want to use information technology to build a safe and reliable and controllable system, so that people can be more convenient to manage and control the environment parameters, and provide items of environmental security, ensure the safety production can be carried out smoothly. In the event of a security accident, the decision maker can assist in making decisions based on the analysis of the data, the expert information base and the reserve plan, and effectively carry out emergency rescue work in a timely and efficient manner.
