Design And Development Of Mountain Torrent Monitoring And Warning System

In recent years, the global climate has changed unpredictably. The frequency of Mountaintorrents, mud-rock flows and other natural disasters get higher and higher. The Mountain torrentdisaster has the characteristics of sudden strong and great damage, and usually causes great lossof life and property, Therefore, Strengthening the prevention of mountain torrent disaster andsafeguarding people’s lives and property safety and hills region’s economic and socialdevelopment is a very necessary and urgent job. In view of this problem, according to thetechnical requirements and related technical specifications of the mountain torrent disastermonitoring and early warning system issued by the ministry of water resources, we carry out thedesign and development of monitoring and warning system of the mountain torrent disaster.The system can collect rainfall and water level information in real time, reflect and analyserainfall and water level changes of the area through the WebGIS system intuitively. Thenaccording to the early warning model, people can determine whether to release early warning. Inorder to provide scientific basis for disaster prevention and mitigation and disaster relief, thesystem releases early warning information to flood prevention workers and the public by Sound,graphics, text information, mobile phone text messages, radio, fax, etc.The overall architecture of the system is divided into data collecting layer, networkhardware layer, data acquisition hardware, data resource layer, application support layer andbusiness application layer. The data collection layer is mainly used to collect and transmitvarious data information; The network hardware layer is composed of network devices, servers,etc and is the hardware foundation of the system operation; The data acquisition layer is acollection of data collection service functions mainly, such as data audit, data validation,processing, warehousing, data exchange, etc；The data resource layer is the foundation ofbusiness application software system, mainly including all kinds of databases, which are used to receive and manage various data information; The application support layer mainly includes allkinds of platform to support the business requirements and function; The business applicationlayer is mainly used to collect information for various business application and provide a unifieduser interface. Using this architecture, stability, extensibility, maintainability and the quality ofthe service of the system will be greatly improved, system expansion and new businessdevelopment will also be more convenient.The system uses templated form, which can be used for multi-level users and is alsosuitable for a variety of application scenarios. Using the WebGIS application based on TopMap,TopMap is suitable for water industry. This software has been proved to be very mature aftermany years’ practice test and meets the special requirements of water industry. In addition, usingthe function provided by the data-sharing middleware platform，each subsystem can realize dataexchange and access of cross-database and meets the requirements of flood control headquartersfor information sharing.This passage first introduces the research background and contents and several keytechniques of the system. Then according to the results of analysis of the system requirementsfrom several angles, this passage introduces in detail the system architecture and database design.Finally, a detailed presentation is made on the screenshot of entire system.
