The frequent occurrence of disastrous weather not only has a great impact on people's lives,but also endangers the stability of ecological environment.In order to reduce the error between the measured meteorological data and real data samples and realize the accurate monitoring of disastrous meteorological observation data,a disaster meteorological observation data monitoring system based on Multi-source Satellite remote sensing is designed.Set temperature and humidity sensors and radiation shields,connect wind speed and direction sensors,rainfall sensors and solar energy controllers into the established module units by the layout of data information transmission network,and complete the hardware design of the monitoring system.The multi-source satellite remote sensing technology is used to define multi-source image space,determine the location of the monitoring extreme point by decomposing the digital satellite image,and the specific value of the similarity measurement index is calculated to complete the registration processing of the disaster meteorological image based on the multi-source satellite remote sensing.According to the upper unit network model,improve the connection form of WINSOCK control,realize the execution program preparation of the monitoring system,and combine the relevant sensor elements to complete the design of the disaster meteorological observation data monitoring system based on the multi-source satellite remote sensing.The experimental results show that the error value between the humidity measurement curve,air pressure measurement curve and wind speed measurement curve of the multi-source satellite remote sensing technology design system and the real meteorological data sample is not more than 2%,and the disaster meteorological observation data can be accurately monitored.
