Research And Implementation Of Forest Fire Monitoring System Based On Wireless Sensor Network

The forest contains a wealth of important natural resources for mankind.Forest fires often occur around the world.Forest fires with characteristic sudden and spread fast,even more with highly destructive.Every forest fires will cause serious consequences,not only a destruction to the natural resources of the forest,but also a threat to the lives of residents' safety near the forest.It is very important that reduce the loss of forest fires on natural resources and effectively prevent and monitor the forest fires.It is imperative to monitor the forest fires with modern Internet technology.With the theoretical support of the full study on causes of forest fires,combined with the environment of forest and the actual needs on function and performance,this thesis applies the ZigBee wireless sensor network technology to the forest fire monitoring system.The sensor node is responsible for real-time collection of temperature,humidity and smoke concentration of the forest area.The data is transferred to the coordinator according to the tree topology.The coordinator transmits the data to the host monitoring terminal through the serial port.The monitoring terminal processes the data and displays it in real time as a line chart.The system achieved prediction of the environmental parameters of the forest in advance.When the predicted value is abnormal,the host will issue a warning ring and the system will send text messages to firefighters to verify.The forest fire monitoring system designed in this thesis makes full use of the main advantages of Zig Bee technology,and uses the wireless network to monitor the environmental parameters of forest fires.According to the functional and performance requirements of the system,the hardware design uses CC2530 chip with DHT11 sensor and MQ-2 sensor program.The design of the lower computer is mainly to design the three nodes of the system,including terminals of the system,router and the coordinator.The main realizations of the function are as follows: forest area parameter acquisition and data transmission,terminal node sleep mechanism,communication relay of forest area data parameter,receiving forest data parameters,set up the network and serial communication.The host is mainly design the detail of the monitoring interface and the function.The main management modules include the user information management module,the personnel information management module,the monitoring data management module,the historical information management module,the early warning module and the data collation module.The main functions of these modules are the information of the registration personnel information management,the monitoring personnel information management,the monitoring Point data information management,historical data statistics and graphical display,alarm and SMS warning mechanism and other functions.Finally,build a test platform based on wireless sensor network for comprehensive testing of the forest fire monitoring system.
