The invention relates to the technical field of geological disaster monitoring, in particular to a landslide analysis method based on deep learning and satellite images. The method comprises the following steps: S1, acquiring a satellite remote sensing image and landform data of a landslide area, and preprocessing the satellite image; S2, constructing a feature set according to a satellite image preprocessing result in combination with the landform data; s3, constructing a training sample set based on the feature set, classifying and positioning the areas conforming to the initial features of the landslide, and outputting the boundary and the distribution range of the landslide; s4, outputting an expression result according to the landslide boundary and the distribution range, and performing multi-index precision evaluation; and if the precision is smaller than the set value, returning to the step 2 and / or the step 3 to carry out adjustment and optimization. The invention aims to provide a landslide analysis method based on deep learning and satellite images so as to realize rapid and high-precision landslide analysis through the satellite images.

The application discloses a kind of self-adapting multi-station ceramic dry pressing forming equipment, it is related to ceramic forming equipment technical field, including frame, frame middle part transverse plate top end rotationally connected with carousel, carousel top end is fixedly connected with several molds, several molds are cross-shaped two two symmetrical settings, frame is sequentially provided with cloth material station, pre-pressing station, pressing station and demolding station along the rotation direction of carousel;The application is circulated by being set cloth material, pre-pressing, pressing, demolding four stations operation, each station can simultaneously execute corresponding process, greatly shorten single blank production rhythm, realize the continuous dry pressing forming of ceramic body, effectively improve production efficiency, it is suitable for scale ceramic production use, by first servo motor simultaneously driving pre-pressing mechanism and demolding mechanism, make pre-pressing plate press down pre-pressing while T-shaped block rises and completes demolding, two station actions are completely synchronous, this design reduces the number of driving elements, reduces equipment manufacturing cost.
