As ancient cities are spaces that represent the development of civilization, it is worth exploring and studying their characteristics and conceptions of land use. In this regard, the focus has turned to the issue of how to achieve the efficient mining of massive urban remote sensing data through human-computer collaboration. In this paper, a new intelligent method of analyzing urban land use characteristics and their cultural significance is proposed;it is feasible, effective, accurate, manageable, and portable. The method is based on a geographic information system (GIS) and a specific algorithm. The city plan was calibrated with the help of satellite remote sensing images and sites. By constructing the "urban element area acquisition and analysis model", various operations for areas in the city plan were realized, including an area value calculation, land use structure calculation, area modulus analysis, area ratio analysis between areas, and determination of the cultural significance of numbers and ratios. Taking the Sui and Tang dynasties capital city of Chang'an as an example, we found the existence of a set of urban planning techniques through area modulus (standard area units) for the first time;it took the market area as the modulus A and the area of Daxing Palace as the expanded modulus 2A, made the area of important areas in the city an integer multiplied by the modulus value (for example, the overall scope of the city is 100A, the rectangular urban area is 90A, and the small city area is 10A), and made the key values and numerical ratios have a cultural significance (such as 4.5, 5.5, 10, 25, 30, 100, 12:10, 1.618:1, 9:5, 45:1, 2:1), reflecting the planning and design concept of the capital city, into which the ancient Chinese deliberately integrated "number, shape and meaning". In addition, we carried out supplementary verification with the Roman city of Timgad and the Japanese city of Heijo-kyo, discovering that they also have design methods for area pl

Conveyor is one of the important mining equipment in the coal mine and the belt is the key component of the conveyor. Once the belt is torn longitudinally, if the measures are not taken in time, the entire conveyor belt will be torn completely, which will cause serious economic losses. To solve this problem, this paper studies a method to detect longitudinal rip of coal conveyor belt by applying MATLAB and knowledge of image processing. By extracting the longitudinal rip part of the image, combining with edge detection, then calculating the area of the longitudinal rip part with a new algorithm, at last comparing this area with the minimum area of the longitudinal rip set by system, it can be judged whether the belt has been longitudinally torn. So control signal can be provided to the control equipment to prevent the conveyor belt from continuing to be torn.

In size analysis of powder's microphotograph it is the key to describe particle boundary and calculate particle area. To describe the particle boundary, the crack code is used in terms of the relation to the boundary in this paper. Based on Green formula, an algorithm of the set area is proposed in this paper. It is efficient and has been applied to the size analysis of the powder microphotograph in mineral processing.
