Implementation Of MouTai Fermentation Process Monitor System Based On WSN

The fermentation of Moutai wine using special natural fermentation technology. Currently, the fermentation process in Moutai Factory is mainly controlled by workers, this is a waste of human labor and the quality of product is unstable. This paper provides an in-depth study of applying Wireless Sensor Networks into the production process of Moutai wine, in order to make the fermentation process self-adaptive. The WSN(Wireless Sensor Networks) fermentation monitor system can solve this problem. By using WSN, we can get real-time and continuous information about the factors of fermentation environment and procedure. This system mainly monitors stacks of grain's temperature and environment temperature and environment humidity, focus on fermentation segment. After the data are gathered, we can process, analyze and make decisions based on the condition of the fermentation and environment.In the process of brewing Moutai, there are a lot of procedures that are entirely relying on human labor. Take fermentation control as an example, currently, worker have to constantly use their hands and arms to determine the temperature, humidity and etc. in order to control the brewing process. There exist a lot of problems in this method: limitations in the techniques, lack of the basic information needed to do data accumulation and analysis; instability of product quality; limited throughput; dependence on the number of proficient workers. All these problems prevent the traditional method from becoming more modernization, information-based and autonomous. Wireless Sensor Networks overcome these problems in traditional methods, and can be easily applied to monitoring systems in Moutai factory. Using Wireless Sensor Network, we don't need to deploy any additional cables, and the system is easy to install, reliable, easy to maintain and expand. Without changing anything in the current working procedure and method, this WSN monitoring system can gather information, switch between working procedures all by itself, and it can also trigger alarm and hint according to user configuration.Based on the specific locations of Moutai factory and these sensors, this paper provide the design of a high level monitoring system, and a detailed description of the system working procedure from hardware level to software level. It is very important for this system to communication securely and efficiently with low-level hardware (base station or sensor nodes). In this system, we use socket (which is based on TCP/IP) to implement the data gathering in high level system. Moreover, thread programming is used to process large amount of data at the same time. When the system gets data, it will first decode this binary stream. This decoding method is based on the format of frames that is set at lower level. After decoding, gathered data are processed for further analyzing. The basic principle of the database table is to hide implementation details from users. Carefully designed table relations can help maintain the consistence of the database and reduce the redundant or error data.In this paper, we provide an in-depth study of wireless sensor network monitoring system design and implementation. The abstract part is which introduces the background of this monitor system, the purpose of development and this paper's architecture. The application foundation of Moutai monitor system explains the way WSN was applied in traditional fermentation techniques, and unveil how this WSN monitor system is used during fermentation procedure. The physical deployment of Moutai Company, the objects that we need to monitor and the distribution of these sensor nodes in the system are introduced for the whole system design. Then the design issues are discussed. First, user needs are specified, based on these specifications, analysis will be then conducted. UML modeling methods are used in this phase to modeling the system. Once we have the example figures, system flow chart will be defined according to the service flow. System communication mechanisms and functional modules are declared, and operations on the database can be then defined. The most important part in this paper is implementation of functional modules. It describes the implementation details of all functional modules. Functional modules are divided into data communication, alter management, monitoring objects management, monitoring information query, organization module, node management and base station parts. Every functional module is discussed in detail in different sections, including logical design, class design, database table design, implementation method and user interface design. Conclusions and future works are discussed also in this paper.The system described in this paper is implemented by C# language, using .NET 2005 develop studio. SQL Server 2000 is used for the database implementation. There are more class libraries in this developing studio than others, and it is more stable and portable, so high level software can be implemented using this developing environment.This system is provided to Moutai factory as a practical monitoring system which can efficiently monitoring and managing the production process, managing all the monitor nodes, managing the base station, organizing and managing Moutai framework, managing alarm, and processing and analyzing the gathered data. The system described has the following functions: 1) gathering information from the environment; 2) managing monitoring station; 3) managing base station; 4) database query (graph, detail) and statistic. The system can support at most 5000 monitor stations at the same time, and can also be easily expanded. During the use of this system, actual number of"plant","workshop","grain pile","base station", and"node"can be changed according to real situation.This system provides a lot of data that can be used to investigate the relation between environment factors and the quality of Moutai product. This information can accelerate the informationization procedure of management, the standardization procedure of operation. And also, the system lays a solid ground and provides technique method for the digitalization of Moutai fermentation process. This system is currently testing in Moutai factory, and it is proved to be stable, portable and expandable. These features of the system achieved our design goal. Extending the use of the system to the whole factory is good or the informationization and digitalization of the control of production procedure. By tracking and recording the raw material, environment and condition information during the production procedure, informationization the control method can be realized.
