Design And Realization Of Forest Fire Monitoring Terminal Based On STM32

The forest plays an important role in maintaining the earth's ecological balance.The damages to the forest environment caused by forest fires are beyond estimation.So it is of great social importance to develop the forest fire monitoring system,monitor the forest environment in real time,and realize the intelligent monitoring and alarming of the forest fire.After fully analyzing the actual demand of the forest fire prevention monitoring system,this paper designs the forest environment monitoring system which consists of three parts,environmental data collection node,environmental monitoring terminal and environment data server.The forest environment data acquisition nodes controlled by CC2530 expand their peripherals as environmental data acquisition modules,such as wet temperature,smoke concentration,carbon monoxide concentration and flame,these collection nodes constitute wireless sensor networks through ZigBee which could then send the collected information of wet temperature,smoke concentration,carbon monoxide concentration and flame to the environmental monitoring terminal;The environmental monitoring terminal using STM32 as the main controller,summary and processing analysis the data uploaded by the collection nodes,and then send the data to the remote server through the GPRS module;The server receives the environmental data uploaded by the environmental monitoring terminal which then is stored in the database,compared and analyzed,establishes the fire warning model which based on the BP neural network,through the data fusion algorithm uses the data collected by the sensors to predict the probability of forest fire,determines the forest environment in which states of the flame,smoldering and no fire,and compares the actual value and the expected value,the error meeting the system requirements.These three parts work respectively and coordinate with each other to achieve forest environmental data sharing,abnormal alarm and so on.The results indicates that the forest fire monitoring system works stably which enables the collection of environmental data of forest's wet temperature,smoke concentration,carbon monoxide concentration and flame as well as the functions of remote sending and remote alarming.Data collection nodes can realize the collection and data uploading of forest environment parameters;The environmental monitoring terminal can realize the disposal and analysis of data sent by multiple collection nodes;The remote monitoring server can realize the receipt and analysis of data uploaded by the environmental monitoring terminal and offer reliable guarantees to maintain the well-balanced forest environment by judging and warning for dangers.
