The method according to claim 6, characterized in that The preset query table is obtained based on the following steps: S201, obtaining the power required by any reference highway service area within a preset time period; S202, obtaining a photovoltaic module installable area corresponding to any reference highway service area as a corresponding target installation area; S203, using preset initial grid units to divide the target installation area corresponding to any reference highway service area to obtain a plurality of corresponding grid areas; the preset initial grid unit is a grid area suitable for installing one photovoltaic module; S204, obtaining the sunshine amount of any grid area corresponding to any reference highway service area within the preset time period; S205, based on the power required by any reference highway service area within a preset time period and the sunshine amount corresponding to each grid area, a target grid area is obtained from multiple grid areas as a grid unit corresponding to the reference highway service area; wherein the target grid area is a square area composed of at least one initial grid unit, and the power that can be generated by the target grid area is greater than or equal to the power required by the corresponding reference highway service area within the preset time period; S206: Based on the power required by any reference highway service area within a preset time period and the corresponding grid unit, the preset query table is formed.

8. The method according to claim 2, characterized in that: The amount of electricity generated by the photovoltaic components of any target highway service area during the current monitoring time period can be obtained based on the amount of sunshine of the photovoltaic components during the current monitoring time period.

9. The method according to claim 2, characterized in that: The target grid area is obtained by the following steps: S161, based on the sunshine amount, distance, shaded area and shaded area change rate corresponding to any grid area, determining the scores corresponding to the sunshine amount, distance, shaded area and shaded area change rate corresponding to the grid area; S162, multiplying the scores corresponding to the sunshine amount, distance, shaded area and shaded area change speed corresponding to any grid area by the corresponding weights respectively and adding the respective multiplication results as the installation weight of the grid area; S163: The grid area corresponding to the largest of all installation weights is used as the target grid area.

10. A real-time monitoring device for energy carbon emission reduction in a highway service area, characterized in that: The device comprises: A first determination module is used to determine the installation location of the photovoltaic modules in any target highway service area; A second determination module is used to install the photovoltaic module at the determined installation location, start the photovoltaic module and perform real-time monitoring on the photovoltaic module; The power monitoring module is used to obtain the power generated by the photovoltaic components of any target highway service area during the current monitoring period and the power consumed by any target highway service area during the current monitoring period at the current monitoring time; The current monitoring time period is the time period between the current monitoring time and the previous monitoring time; The display module is used to obtain the difference between the amount of electricity generated by the photovoltaic components of any target highway service area during the current monitoring period and the amount of electricity consumed by any target highway service area during the current monitoring period, and to display it visually; wherein, the amount of electricity difference with a negative value is displayed in a set color.
