Abstract: In order to improve remote monitoring ability of local meteorology in remote mountainous areas and reduce adverse impact of meteorological disasters on crop growth in mountainous areas, a design scheme of meteorological remote monitoring and early warning system was proposed．Structure of front-end acquisition terminal was optimized, synchronous acquisition and remote transmission of meteorological data and image data was realized by using microelectronic detection technology and 4G wireless communication network．Multiple acquisition terminal data was integrated by using remote server, the data was analyzed by using intelligent recognition algorithm, and meteorological monitoring and early warning results were output．The optimized design scheme has advantages of simple structure and low construction cost．Experimental results showed that data transmission was stable and could meet transmission rate requirements of agrometeorological data．
