[0089] Step S826: based on the information on the selection of types with no environmental impact, retrieve the number of values ​​of the selection types with no environmental impact.

The number of values ​​of the types selected without environmental impact is retrieved through the information of the types selected without environmental impact, which is convenient for subsequent use.

[0091] Step S827: When the value of the number of types selected without environmental impact is greater than one, the information of the types selected without environmental impact is used as the perception selection type information.

[0092] Among them, when the value of the number of types selected without environmental influence is greater than one, it means that no selection is needed at this time, so the information of the types selected without environmental influence is used as the perception selection type information.

[0093] Step S828: When the value of the number of selection categories without environmental impact is less than one, the matching selection category information is determined according to the building impact category information and the weather impact category information, and the matching selection category information is used as the perception selection category information.

[0094] Among them, the matching selection category information refers to the category information after matching and selecting the perception category.

[0096] Reference Figure 6 , the method for determining the building impact category information includes the following steps: Step S8231: Based on the location building impact value and the fall into the preset building impact range, the building impact selection type information is selected to determine.

[0097] Among them, the building influence interval refers to the influence reference interval corresponding to different perception types when they are affected by buildings, and the building influence interval is obtained after being pre-input by the operator. The selected category information refers to the perception category information selected due to the influence of surrounding buildings.

[0098] Step S8232: Determine whether the location building impact value is added to the number of people impact value. If yes, execute step S8233; if no, execute step S8237.

[0099] Among them, by judging whether the location building influence value is added with the number of people influence value, it is judged whether the number of people has an impact on the selection of types.

[0100] Step S8233: Retrieve the surrounding building area value based on the surrounding building type information.

[0101] Among them, the surrounding building area value refers to the area value corresponding to the surrounding buildings. When the location building influence value is added with the number of people influence value, it means that the number of people at this time has an impact on the selection of type. Therefore, the surrounding building area value is retrieved through the surrounding building type information to facilitate subsequent use.

[0105] The number of people impact deviation value refers to the deviation value when there is a deviation in the impact caused by the number of people. The difference between the number of people impact value and the number of people-area benchmark impact value is calculated and used as the number of people impact deviation value for subsequent use.

[0107] Among them, the population impact deviation interval refers to the impact reference interval corresponding to different perception types when they are affected by the population impact deviation, and the population impact deviation interval is obtained after pre-input.

[0108] Step S8237: select the building impact category information as the building impact category information.

[0109] Among them, when the location building influence value does not include the number of people influence value, it means that the number of people has no effect on the selection of category at this time, so the building influence selection category information is used as the building influence category information, thereby improving the accuracy of the obtained building influence category information.

[0110] exist Figure 5 In step S828, in order to further ensure the rationality of the collocation selection type information, it is necessary to further analyze and calculate the collocation selection type information separately, which is described in detail in the following steps. The method for determining the collocation selection type information includes the following steps: Step S8281: When the building impact type information and the weather impact type information have mutual impact, the building impact type information and the weather impact type information that have mutual impact are regarded as the mutual impact type information.

[0114] Step S8283: Determine whether the category mutual influence value is greater than a preset category mutual influence reference value. If yes, execute step S8284; if no, execute step S8285.

[0115] Among them, the category mutual influence benchmark value refers to the minimum influence value corresponding to the positive mutual influence between the perception category affected by the surrounding buildings and the perception category affected by the weather. By judging whether the category mutual influence value is greater than the preset category mutual influence benchmark value, it is judged whether it is necessary to select from the mutually influencing categories.

[0116] Step S8284: Sort from large to small based on the mutual influence values ​​of the categories, and combine the building influence category information corresponding to the mutual influence value of the category with the first category in the sorting result with the weather influence category information as the mutual influence selection category information.

[0117] Among them, when the category mutual influence value is greater than the preset category mutual influence benchmark value, it means that it is necessary to select from the mutually influencing categories at this time. Therefore, the category mutual influence values ​​are sorted from large to small, and the building influence category information corresponding to the category mutual influence value with the first sorting result is combined with the weather influence category information as the mutual influence selection category information, thereby improving the accuracy of the obtained mutual influence selection category information.

[0118] Step S8285: Select the building impact category information and weather impact category information except the mutual impact category information and execute the preset individual impact category selection method to select to form individual impact selection category information, and use the individual impact selection category information as the mutual impact selection category information.

[0119] Among them, the separate impact category selection method refers to a method for selecting perception categories that do not influence each other, and the separate impact category selection method is obtained after pre-input. The separate impact selection category information refers to category information for selecting perception categories that do not influence each other. When the category mutual impact value is not greater than the preset category mutual impact reference value, it means that it is not necessary to select from the mutually impact categories at this time. Therefore, the building impact category information and weather impact category information other than the mutual impact category information are selected and the preset separate impact category selection method is executed to select to form separate impact selection category information, and the separate impact selection category information is used as the mutual impact selection category information, thereby improving the accuracy of the obtained mutual impact selection category information.
