Description

technical field [0001] The invention relates to the technical field of civil aviation monitoring equipment, in particular to a mobile sensor network airport noise monitoring coverage optimization method and device. Background technique [0002] The existing airport noise automatic monitoring systems are all developed by foreign countries. The cost is high, and the noise calculation model, noise evaluation index, software and hardware design do not specifically consider the operating characteristics of my country's airports, making it difficult to give full play to their effectiveness in the actual application process. The core technology of the system Subject to people. More importantly, the current airport noise monitoring system lacks the support of theoretical methods and technologies. The layout of its monitoring points is mainly completed with the help of expert experience. Due to the limitations of monitoring modes and costs, the number of monitoring points is small, an...

Problems solved by technology

In quite a lot of applications, because the sensor nodes are randomly deployed in the target monitoring area, and the sensor nodes cannot readjust the position according to the specific needs of monitoring, this makes the coverage effect of the sensor network often unsatisfactory.

[0004] Most of the existing airport noise monitoring and coverage methods and devices cover the target area evenly, and these noise monitoring equipment with uniform coverage and distribution are fixed installations. Therefore, it has been found through long-term use that this traditional uniform coverage layout The current airport noise monitoring system has the following defects: one, waste a lot of resources, because in the airport noise monitoring process, if want to achieve ideal coverage, then need to layout a large number of airport noise monitoring devices, because the noise distribution of the airport is Uneven, so it will cause low coverage in some areas, unable to meet the needs of airport noise monitoring, and high coverage in some areas, wasting a lot of resources; There is a lot of noise in the noise information, which is not conducive to the analysis and processing of the later information, which makes the information processing process complicated and affects the speed of information processing; 3. Since the noise monitoring devices are evenly distributed at various positions in the airport, they do not have the ability to automatically adjust their positions. ability
