Design And Implementation Of Agricultural Greenhouse Monitoring System Based On ARM And Multi-sensor Information Fusion

Agricultural production runs through the continuous development of human society.With the various stages of human history development,agricultural production has experienced three main stages,from primitive to traditional to modernization,which is the cornerstone of human survival and continuous development,and the pillar of human civilization.Agricultural production is a basic industry related to people’s life.Since the eighteen,the work of poverty alleviation has been an important work in our country.The nineteen major is the key to the work of precision poverty alleviation.With the rapid development of information technology,various high-tech technologies are widely used in the production,operation and service of agriculture.It has gradually replaced the traditional farming methods and effectively collected information from the agricultural greenhouse environment.Based on ARM,the agricultural greenhouse environment information monitoring system is designed,which can be designed to achieve multi sensor information fusion,which can play the function of fire prevention,anti-theft and drought prevention to the agricultural greenhouse.The system uses the ARM920 T series S3C2440 chip as the central processor.Through the multi-sensor module composed of temperature humidity sensor,infrared sensor and smoke sensor,the field information of agricultural greenhouse is collected in real time.After normalization of the information,the central processor is used to judge and deal with the information,and the information is fused,and the final pass is done.Through the 4G network communication module,we send the reasonable and accurate information to the user’s mobile phone terminal,so as to play the purpose of fire protection,burglar prevention and drought prevention.The software design of the system mainly includes: the program design of information fusion algorithm,the extended CAN bus driver design.Through the multi-sensor information fusion technology,the accuracy of monitoring data in agricultural greenhouse has been effectively improved.A complementary fusion algorithm,combined with the combination of fuzzy set theory and D-S evidence theory,is used to clarify the process of solving the reliability of evidence,and the method of defining the coefficient of evidence decision is adopted to effectively improve the reliability of the fusion results of multi information sources.An example of information fusion is used to verify the feasibility of the algorithm.Finally,a client program based on Android is designed to display the monitored environmental data in real time.
