Abstract:

The frequent occurrence of disastrous weather not only has a great impact on people's lives, but also endangers the stability of the ecological environment. In order to reduce the error between the measured meteorological data and the real data samples and realize the accurate monitoring of the disaster meteorological observation data, a disaster meteorological observation data monitoring system based on Multi-source Satellite remote sensing is designed. The temperature and humidity sensor and radiation protection cover are set. According to the layout of data information transmission network, the wind speed and direction sensor, rain sensor and solar controller are connected to the established module unit to complete the hardware design of the monitoring system. The multi-source satellite remote sensing technology is used to define the multi-source image space, determine the location of the monitoring extreme point by decomposing the digital satellite image, and calculate the specific value of the similarity measurement index 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 complete the design of the disaster meteorological observation data monitoring system based on Multi-source Satellite Remote Sensing in conjunction with relevant sensor elements. 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.
