2results about How to "Improve site selection efficiency" patented technology

The application discloses an H-ADCP installation position optimization method based on cross-section traversal scanning, which comprises the following steps: 1) selecting a cross-section to be installed, using a sailing ADCP to measure flow and synchronously observing water level under different water level stages or flow velocity stages, and calculating the average flow velocity of each cross-section; 2) importing the flow velocity data into a cross-section terrain model, dividing candidate units, traversing and extracting representative flow velocities, and generating a flow field and a standard deviation distribution diagram; and 3) comprehensively analyzing and determining the final position through multi-dimensional quantitative evaluation of flow velocity standard deviation, random uncertainty and correlation coefficient, combined with on-site conditions such as terrain adaptability and interference degree. The method disclosed by the application has high site selection efficiency and is suitable for H-ADCP installation site selection in rivers, lakes and other water areas, and is helpful to improve the online monitoring accuracy of river flow.

The application discloses a kind of based on multi-factor fusion's electric bicycle battery swap cabinet site selection suitability evaluation method, belong to urban traffic supporting facilities site selection technical field.For the problem that existing battery swap cabinet site selection lacks quantitative analysis, low degree of automation, the application fuses analytic hierarchy process AHP, geographic information system GIS, preference order structure evaluation method PROMETHEE and Python-ArcPy technology, first constructs construction, traffic, ecological three-dimensional index system, and determines the index weight by AHP;Then realize data cleaning, differential normalization and weighted superposition automatic calculation using Python-ArcPy, output comprehensive score;Again, extract high suitable area as candidate point by GIS;Finally, calculate net flow value ranking using PROMETHEE method, combined with service radius and field research screening optimal point.The application realizes site selection whole process automation and spatial visualization, significantly improves evaluation efficiency and accuracy, and can be popularized to similar new energy supporting facilities planning.
