Auxiliary measurement equipment and measurement method for multi-point sampling of urban wind environment

Abstract

The invention discloses an auxiliary measuring device and measuring method of urban wind environment multi-point sampling. The auxiliary measuring device comprises a movable timing-type wind measurement instrument, an affiliated GPRS device and an affiliated data memory. In measurement, urban blocks are used as basic units, and wind environment measuring points are arranged on the height of pedestrians; the auxiliary measuring devices are arranged and numbered according to the set wind environment measuring points, and the setting of measured parameters is simultaneously completed; the auxiliary measuring devices automatically measure wind environment data and geographical coordinate data according to the measured parameters; and after the measurement is completed, all wind environment data and geographical coordinate data are gathered, data entry is carried out with the measuring point numbers serving as identification marks, and a panel database of the urban wind environment is formed. According to the invention, the defects such as low efficiency, high cost and rough precision of manual wind environment measurement are effectively avoided, and a high-efficiency, intelligent and comprehensive method for collecting large-sample, large-range, high-precision and multi-dimensional data is provided for urban large-scale wind environment analysis, monitoring, programming and layout optimization.

Description

technical field [0001] The invention relates to a multi-point, timing sampling measurement method and auxiliary measurement equipment for wind environment data in wind environment analysis of urban planning, belonging to the field of wind environment measurement in urban planning. Background technique [0002] As an important element of urban microclimate, urban wind environment plays an important role in the diffusion of atmospheric pollutants, the resolution of heat island effect, the perception of heat / wind comfort in open spaces, and the wind safety of high-rise buildings. play a role that cannot be ignored. A good urban wind environment, especially at the pedestrian height, can provide urban residents with a healthier and more comfortable outdoor activity platform. How to deal with urban wind and environment problems in urban planning and design is an urgent need for the healthy development of cities.

AI Technical Summary

Problems solved by technology

[0003] So far, in the field of architecture and urban planning, more and more attention has been paid to the accurate detection and analysis of urban wind environment, and a large number of on-site monitoring work of wind environment data is being carried out. However, although there are various types of wind environment measuring instruments, including mechanical Wind direction and anemometers, thermal anemometers, ultrasonic wind anemometers, etc., but they are all measuring instruments for a single, independent measurement point; traditional measurement methods are only for specific measurement points and specific time nodes; the existing wind The measurement method of the environment has a single function. For the measurement of the wind environment at multiple measurement points in a specific area of ​​the city, it needs to go through multiple and repeated human work, which has problems such as low efficiency, high cost, and rough precision.

Therefore, the current traditional wind environment data collection work is not suitable for large-scale urban wind environment analysis, nor can it provide data support for urban planning optimization strategies
