The construction site is a construction site in the process of being constructed or the construction is completed within a preset time period. The construction site comprises soil, vegetation and a green net (green net cover for construction), and the soil with different soil properties, the vegetation with different colors and the green net with confusion have multispectral information corresponding to each other. The multispectral information of the construction site refers to multispectral information including soil, vegetation, green nets and the like. In order to monitor construction disturbance conditions of the construction sites in different time periods, multispectral information of the construction sites collected in each time period is compared with multispectral information of the construction sites collected in the previous time period respectively, so that multispectral information change conditions of the construction sites corresponding to each current time period are obtained, disturbance conditions of construction corresponding to each current time period on water and soil can be obtained based on the multispectral information change conditions, and the disturbance conditions of the construction sites on water and soil can be continuously tracked through multi-time period compact analysis, so that the disturbance conditions of the water and the soil in the construction process can be timely mastered.

The standard spectral information of each water and soil element refers to a standard value of the spectral information of each element. When the multispectral information of the construction site acquired by the multispectral instrument is acquired, comparison can be carried out according to the standard spectral information, and then the type of the site contained in the construction site can be determined, and the type of the site represents the vegetation condition of the soil.

In one embodiment, a plurality of construction time periods in the construction process are determined according to a preset acquisition frequency; the preset acquisition frequency comprises once a quarter and once a month in a rainy season.
The construction time periods in the construction process are determined according to the preset acquisition frequency, and the number of the construction time periods in the construction process is the ratio of the construction period to the preset acquisition frequency. For example, when the preset collection frequency is once in each quarter and the construction period is six months, the construction time period in the construction process is two. The preset acquisition frequency in the construction process is preset in the server, the preset acquisition frequency can be set according to the predicted construction period, and the longer the predicted construction period is, the smaller the preset acquisition frequency is; the shorter the construction period is expected, the larger the preset acquisition frequency is. For example, the construction period is six months, and the preset collection frequency may be once a month; when the construction period is two months, the preset acquisition frequency can be once every two weeks. When no continuous extreme weather exists after the whole construction process is finished, the preset acquisition frequency comprises once in a quarter. When continuous extreme weather occurs during construction, the preset acquisition frequency may be set to once a month. According to the preset acquisition frequency, the flying equipment carries a multispectral instrument to monitor construction sites and key construction positions.
In this embodiment, the construction time period in the construction process is determined by presetting the acquisition frequency, so that the construction site and the key construction position can be monitored more regularly.
In one embodiment, extreme weather includes: and (3) heavy rainfall weather with rainfall larger than a preset value.
The preset value is preset and is used for judging rainfall intensity. The rainfall is larger than a preset value, which indicates that the weather is heavy rainfall weather. The rainfall is not less than the preset value, which indicates that the weather is not heavy rainfall. Heavy rainfall weather is one of extreme weather, which also includes continuous rainfall, and weather that is continuous rainfall and is heavy rainfall.
In this embodiment, when extreme weather time such as heavy rainfall occurs, the water and soil disturbance conditions of the construction site and the key construction part are monitored, so that the influence of the extreme weather on the water and soil disturbance can be timely dealt with.
In one embodiment, if the disturbance condition of the construction to the water and soil obtained after the construction is completed can not pass through the water and soil conservation acceptance check, indicating the multispectral instrument to carry out multispectral information on the construction site again at the preset time after the construction is completed; comparing the multispectral information of the construction site acquired again after construction with the multispectral information acquired for the first time; and (5) evaluating whether the test is accepted by water and soil conservation according to the comparison result.
When receiving the multispectral information sent by each acquisition time, the server compares the multispectral information with the standard spectral information to determine each area and the area of each area.
The acceptance of water and soil conservation refers to that the water and soil conservation of a construction site meets the national, local or industry standards. The water and soil conservation acceptance includes the minimum area occupied by each site of the construction site. After construction is completed, checking whether the water and soil disturbance condition of the construction site can pass through water and soil conservation inspection, and when the water and soil disturbance condition of the construction site can pass through water and soil conservation inspection, only collecting multispectral information of the construction site once after the construction is completed. When the water and soil disturbance condition of the construction site cannot pass through the water and soil conservation test, at least one multispectral information acquisition is needed to be carried out on the construction site after the construction is completed. And comparing the multispectral information of the construction site acquired again after the construction is completed with the multispectral information acquired for the first time after the construction is completed. And (5) evaluating whether the test can pass the water and soil conservation test or not according to the comparison result. And when the comparison result is that the acquired multispectral information is compared with the acquired multispectral information for the first time, and the determined area of each field meets the minimum area requirement of water and soil conservation check acceptance, determining that the construction of the current construction field passes the water and soil conservation check acceptance. The multispectral information of the construction site collected again can pass through water and soil conservation acceptance, because after the construction is finished, vegetation newly planted in the construction site grows to a certain degree or the construction site is partially or completely recovered after the multispectral information collected for the first time.
In this embodiment, after the construction is finished, the multispectral information of the construction site is collected again after the multispectral information is collected for the first time, and then whether the multispectral information can pass through the soil and water conservation inspection is estimated according to the comparison result of the multispectral information and the multispectral information, and the vegetation needs time to grow or recover is fully considered, so that the collected multispectral information is closer to the real soil and water disturbance condition after the construction is finished.
