In the prior art, a photovoltaic power generation system is generally installed on a roof, a ground, a hillside and a water area of a building, and is large in partial area, inconvenient for surveying in a special area and needs a large amount of manpower and material resources. The method specifically comprises the following steps:

1) manpower and material resources are wasted: personal roof surveying is assisted by various devices such as at least two persons, an engineering vehicle, a ladder, a measuring tool, a safety rope and the like; the large-scale ground, hillside, water area, factory building and other surveys need more manpower and material resources, and meanwhile need precise computing equipment to be matched with professional engineering personnel to perform professional precise computing;

The loading amount determining apparatus 1 may be located in a user device or a network device. The following describes in detail the loading amount determination apparatus 1 in a network device as an example.

When the loading capacity determining device 1 is located in a network device, the network device and one or more corresponding user devices communicate with each other to determine the loading capacity of the photovoltaic power generation system. Specifically, a user selects a building through user equipment, and the user equipment sends the building selected by the user through the user equipment to corresponding network equipment; the network equipment 1 determines the loading amount of a photovoltaic power generation system which can be loaded in a building according to the building selected by a user; subsequently, providing the loading amount to the user; the user equipment receives the machine loading amount of the loadable photovoltaic power generation system corresponding to the selected building, which is returned by the network equipment; the load is then presented to the user device.

Herein, the total installed capacity refers to the total peak power of the components (i.e., photovoltaic panels, or solar panels) actually installed in the photovoltaic power generation system under standard test conditions. Typically in units of kw (kilowatts) or mw (megawatts). The power of the photovoltaic panels has various specifications, and 260 watts is taken as an example, that is, under a rated condition, the instantaneous power of one photovoltaic panel is 260 watts, and if the photovoltaic power generation system is loaded with 100 photovoltaic panels, the loading capacity of the photovoltaic power generation system is 100 × 260w — 26 kw.

Here, if the first determining device 201 determines the loading amount of the photovoltaic power generation system that can be loaded in the building by real-time calculation according to the building selected by the user, the first determining device 201 calculates several photovoltaic power generation panels that can be loaded on the roof of the building according to the area to be loaded corresponding to the building, such as the roof area of the building, so as to determine the loading amount of the photovoltaic power generation system that can be loaded in the building based on the power of each photovoltaic power generation panel.

For example, a user clicks a certain building in a satellite map presented by a mobile application of the mobile device, and the first determining device 201 determines the machine loading amount of the loadable photovoltaic power generation system corresponding to the building according to the building; the provisioning means 202 then provides the loading to the user in the mobile application, such as directly next to the building that the user clicks on, or by invoking one or more dynamic page techniques such as JSP, ASP or PHP at a location such as a new application page or a newly popped hover box.

In addition, the loading capacity determining device 1 is flexible to use, can be adapted to any user equipment or equipment system, is simple to operate, is suitable for any crowd and has strong expandability.

Preferably, the first determining device 201 determines the loading amount of the photovoltaic power generation system which can be loaded in the building according to the building selected by the user and by matching the query in the loading database.

Specifically, the user selects a corresponding building through interaction with the user device, for example, in a mobile application of the mobile device or in a web page on the web side, for example, the name of the building is input in an input box of the mobile application or the web page, or a certain building is clicked in a satellite map presented by the mobile application or the web page; the first determining device 201 directly matches the query in an installed database in which, for example, the installed amount of the loadable photovoltaic power generation system corresponding to each building is stored, according to the building selected by the user, thereby determining the installed amount of the loadable photovoltaic power generation system corresponding to the building selected by the user.

Here, the installed database stores a mapping relationship between each building and its corresponding installed amount of the loadable photovoltaic power generation system, which may be calculated and stored in advance by the installed amount determination device 1 or obtained by uploading by each user device. The installed amount database may be located in the installed amount determination apparatus 1 or may be located in a third-party device connected to the installed amount determination apparatus 1 via a network.

Here, the user selects any building, for example, clicks any building roof, and the machine loading amount determining device 1 can obtain the machine loading amount of the loadable photovoltaic power generation system of the selected building, so that the operation is convenient, simple and quick, and the use experience of the user is improved.

Preferably, the first determination means comprises an area determination unit 201a (not shown) and a calculation unit 201b (not shown). The area determining unit 201a determines an area to be loaded corresponding to a building according to the building selected by a user; the calculation unit 201b calculates a loading amount of the photovoltaic power generation system which can be loaded in the region to be loaded according to the region to be loaded.

Specifically, if the machine loading amount of the building selected by the user and capable of loading the photovoltaic power generation system corresponding to the building needs to be calculated in real time, the area to be loaded with the photovoltaic power generation system in the building needs to be known, so that the area determining unit 201a determines the building selected by the user according to the building search keyword input by the user or the positioning information based on the user, and determines the area to be loaded corresponding to the building through real-time calculation, matching query and the like, or the user can circle the framed area to be loaded only by manually clicking a few main points in a map; subsequently, the calculating unit 201b calculates the number of photovoltaic panels that can be loaded in the region to be loaded according to the region to be loaded, based on the area of the region to be loaded and the area required for loading each photovoltaic panel, so as to calculate the loading amount of the photovoltaic power generation system that can be loaded in the region to be loaded based on the power of each photovoltaic panel.

The manner of determining the region to be installed by the region determining unit 201a includes at least any one of the following:

Specifically, the area determination unit 201a determines the current location of the user, for example, by invoking a positioning device, such as a GPS, carried by the user equipment used by the user; or, the user equipment may call a positioning device such as a GPS thereon to obtain its own current position, and then actively send the current position to the area determining unit 201a, where the area determining unit 201a obtains the current position of the user equipment; subsequently, the area determination unit 201a determines in which building the user is currently located based on the current location of the user, and matches the query in a building database in which, for example, the areas to be loaded corresponding to the respective buildings are stored according to the name or longitude and latitude information of the building, thereby determining the areas to be loaded of the building.

Or, the user inputs a building search keyword in an input box of a web page of a mobile application or a PC end of the mobile device, for example, the input box inputs all or part of a name, longitude and latitude information, description information, or uploads a picture of a building, and the like of the building, the area determining unit 201a obtains the building search keyword input by the user, and directly performs a matching query in a building database based on the building search keyword, or determines the building to be searched by the user in a picture recognition mode, an information matching mode, and then performs a matching query in the building database, and for example, the building database stores the to-be-installed areas corresponding to the buildings, thereby determining the to-be-installed areas.

Here, the building database stores a mapping relationship between each building and its corresponding to-be-loaded area, which may be calculated and stored in advance by the loaded amount determining apparatus 1, or obtained by uploading by each user equipment. The building database may be located in the loading amount determination apparatus 1, or may be located in a third-party device connected to the loading amount determination apparatus 1 via a network.

Or, the user performs a certain framing operation in a satellite map provided by a mobile application of the mobile device or a web page at the PC end, for example, by framing a plurality of points in the satellite map so that the plurality of points form a framed area, or by dividing a plurality of lines in the satellite map to form a framed area; the area determining unit 201a may determine the area to be loaded based on the frame selection operation performed by the user in the map.

More preferably, the area determination unit 201a further determines a plurality of corresponding marker points based on a frame selection operation performed by the user in a map corresponding to the building; and determining the area to be loaded according to the longitude and latitude information of the plurality of marking points.

Specifically, the user performs a certain framing operation on the map corresponding to the building, where the framing operation includes, but is not limited to, a pointing operation, a circling operation, a line drawing operation, and the like, and the framing operation may have corresponding mark points, and the area determining unit 201a determines a plurality of corresponding mark points based on the framing operation performed on the map by the user. For example, for the pointing operation, the area determination unit 201a may directly take several points pointed by the user as the mark points; for the circle drawing operation, the area determining unit 201a may define several mark points from the circle drawn by the user, and the number of the defined mark points may be adjusted according to the size of the circle drawn by the user, where the circle drawn by the user may be a circle such as a perfect circle, an ellipse, or other irregular circle or polygon; for the scribing operation, the user forms a framed area by scribing a plurality of lines in the satellite map, and the area determination unit 201a may take, for example, a point where the plurality of scribed lines intersect as a marking point. Subsequently, the area determining unit 201a determines the to-be-loaded area corresponding to the frame selection operation of the user through conversion calculation according to the latitude and longitude information of each mark point.

Here, for these frame selection operations of the user, trigger conditions for starting and ending of the frame selection operations may be defined by the system or the user, for example, a "start" button and an "end" button may be provided in an interface of the mobile application, and when the user clicks "start", the user may frame the area to be mounted on the satellite map displayed by the mobile application, for example, the user clicks a plurality of points on the satellite map, and then, the user may click the "end" button, that is, the user is considered to have completed selecting the area to be mounted, and the area determining unit 201a then determines the area to be mounted corresponding to the user's frame selection operation according to the longitude and latitude information of the plurality of points. Or, the system may define that when the user finishes drawing a closed graph, that is, when the user performs a circling operation to close the corresponding graph, the selection of the region to be installed is considered to be completed, where the closed graph may be a perfect circle, an ellipse, or another irregular circle or polygon, and the region determining unit 201a then determines, according to the closed graph, the region to be installed corresponding to the circling operation of the user.

It should be understood by those skilled in the art that the above-described block selection operations are only exemplary, and other block selection operations that may occur now or later, such as may be suitable for use with the present invention, are also included within the scope of the present invention and are hereby incorporated by reference.

It should also be understood by those skilled in the art that the above-mentioned method for determining the region to be installed is only an example, and other methods for determining the region to be installed, which may be present or later come, such as being applicable to the present invention, are also included in the scope of the present invention and are herein incorporated by reference.

Here, based on the frame selection operation of the user on the map, the machine loading amount determining device 1 can determine the corresponding to-be-loaded area in real time, and calculate and obtain the corresponding machine loading amount of the loadable photovoltaic power generation system, so that the use experience of the user is further improved.

More preferably, the area determining unit 201a obtains a candidate area corresponding to the building according to the building selected by the user; and preprocessing the candidate area, and taking the preprocessed candidate area as the area to be loaded.

Specifically, since there may be some areas on the roof of the building where the photovoltaic power generation system cannot be loaded, such as a chimney, a water tank, and the like, it is necessary to delete the areas where the photovoltaic power generation system cannot be loaded, that is, the areas corresponding to the areas where the photovoltaic power generation system cannot be loaded cannot be used to calculate the loading amount of the loadable photovoltaic power generation system. When a user selects a building or performs a certain frame selection operation, the area determination unit 201a obtains a corresponding candidate area according to the building selected by the user or the frame selection operation performed by the user, where the candidate area refers to the whole roof area of the building or the area selected by the user frame; subsequently, the area determination unit 201a performs preprocessing on the candidate area, for example, the satellite image corresponding to the candidate area is preprocessed through image recognition, and since the general color of obstacles such as a chimney and a water tank is darker than that of other open places on the roof, the candidate area, that is, the area of the roof of the building or the area framed by the user, such as the chimney and the water tank, can be removed through image color algorithm recognition, and the preprocessed candidate area is used as the area to be loaded, so as to calculate the loading amount of the loadable photovoltaic power generation system.

It will also be understood by those skilled in the art that the above-described methods of preprocessing candidate regions are merely exemplary, and that other methods of preprocessing candidate regions, which may be currently or later become known, are also included within the scope of the present invention and are hereby incorporated by reference.

Herein, the machine loading amount determining device 1 eliminates some areas such as a chimney and a water tank which may affect the installation of the photovoltaic power generation system, so as to determine the area to be loaded, and calculates and obtains the corresponding machine loading amount which can be loaded with the photovoltaic power generation system, so that the calculation of the machine loading amount is more accurate, and the use experience of a user is further improved.

Preferably, the loading amount determining means further includes updating means (not shown). The updating device establishes or updates the building database according to the region to be loaded determined based on the frame selection operation of the user.

Specifically, according to the foregoing framing operation performed by the user in the map, the area determination unit 201a determines the machine-waiting area corresponding to the framing operation by the user, for example, the user frames the entire roof of a certain building to determine the machine-waiting area of the building, such as the entire roof area of the building, so that the updating device stores the determined machine-waiting area in the building database, such as the mapping relationship between the building and the roof area thereof in the building database, thereby establishing or updating the building database.

Here, for the same building, the areas to be installed uploaded by the frame selection operations of different users may be different, and the updating device may further perform processing such as screening, weighted calculation, and the like on the different areas to be installed based on predetermined conditions, for example, directly delete data that significantly differs from the areas of the areas to be installed uploaded by other users, and average the screened data to serve as the areas to be installed of the building, or allocate corresponding weight values to the areas to be installed uploaded by different users based on credit ratings of different users, so as to perform weighted calculation on the areas to be installed, obtain the areas to be installed of the building, and further store the areas to be installed in the building database, thereby implementing establishment or updating of the building database.

The building database stores mapping relations between buildings and corresponding zones to be installed, and for data such as zones to be installed of buildings which are not stored in the building database, after a user selects a roof of the building and the like to determine the zones to be installed, the building database is uploaded to be called by other users.

Further, the updating device may also store the obtained loading amount of the photovoltaic power generation system in the loading database according to the real-time calculation of the calculating unit 201b, so as to be directly called by other users. The installed database may preferably be the same database as the building database, or may be two separate databases.

It will be understood by those skilled in the art that the above described manner of creating or updating a database is merely exemplary, and that other existing or future created or updated databases, as may be suitable for use with the present invention, are also intended to be included within the scope of the present invention and are hereby incorporated by reference.

Preferably, the calculating unit 201b calculates a loading amount of the photovoltaic power generation system which can be loaded in the area to be loaded according to the area to be loaded and by combining with the auxiliary information corresponding to the area to be loaded;

wherein the auxiliary information comprises at least any one of:

altitude information of the region to be loaded;

weather information of the region to be loaded;

and orientation information of the region to be loaded.

Specifically, when the calculation unit 201b calculates the loading amount of the loadable photovoltaic power generation system in the region to be loaded, auxiliary information can also be considered, the auxiliary information includes but is not limited to altitude information, meteorological information, orientation information, longitude and latitude information and the like of the region to be loaded, for example, if the orientation information of the loading area is north, due to insufficient illuminance or the like, the machine loading amount on which the photovoltaic power generation system can be loaded is small, and if it is south, the machine loading amount on which the photovoltaic power generation system can be loaded is large, and the calculation unit 201b may, for example, use a preset formula, the auxiliary information is converted to a certain extent, so as to calculate the loading amount of the photovoltaic power generation system which can be loaded in the area to be loaded, further, the calculating unit 201b may also determine a corresponding weight for each auxiliary information, and calculate the loading amount of the photovoltaic power generation system which can be loaded in the area to be loaded by combining the weight. In this case, different auxiliary information may result in different loading amounts of the photovoltaic power generation system, for example, for a loading-standby area with a sunny weather, the loading amount of the photovoltaic power generation system is larger than for a loading-standby area with a rainy weather.

It should be understood by those skilled in the art that the above-mentioned auxiliary information is only an example, and other existing or future auxiliary information, such as may be applicable to the present invention, should be included within the scope of the present invention and is hereby incorporated by reference.

In step S301, the loading amount determination device 1 determines the loading amount of the photovoltaic power generation system that can be loaded in the building according to the building selected by the user.

Specifically, through interaction with the user device, for example, in a mobile application of the mobile device, or in a web page on the web side, the user selects a corresponding building, for example, the name of the building is input in an input box, or a certain building is clicked in a map, or a certain area is selected as the corresponding building in the map, where the building is a building in a broad sense, which may be a certain building or several buildings, or only an open floor; in step S301, the loading amount determining apparatus 1 obtains the building selected by the user through interaction with the user equipment, for example, through one or more calls to an Application Program Interface (API) provided by the user equipment or through other appointed communication methods, and thereby determines the loading amount of the photovoltaic power generation system that can be loaded in the building through direct matching in a database, or through real-time calculation according to the roof area of the building, or the like.

Here, if the loading amount determining device 1 determines the loading amount of the photovoltaic power generation system that can be loaded in the building in a real-time calculation manner according to the building selected by the user in step S301, then in step S301, the loading amount determining device 1 calculates several photovoltaic power generation panels that can be loaded on the roof of the building according to the area to be loaded corresponding to the building, for example, the roof area of the building, and determines the loading amount of the photovoltaic power generation system that can be loaded in the building based on the power of each photovoltaic power generation panel.

In step S302, the load amount determination device 1 provides the load amount to the user.

Specifically, in step S302, the loading amount determination apparatus 1 provides the loading amount to the user in the relevant application or page by calling one or more dynamic page technologies such as JSP, ASP, or PHP, or other agreed presentation technologies or manners according to the loading amount of the loadable photovoltaic power generation system corresponding to the building determined in step S301. For example, the user clicks a certain building on a satellite map presented by a mobile application of the mobile device, and in step S301, the loading amount determining device 1 determines the loading amount of the loadable photovoltaic power generation system corresponding to the building based on the selected building; subsequently, in step S302, the loading amount determination apparatus 1 provides the loading amount to the user in the mobile application, such as directly beside the building clicked by the user, or by calling a dynamic page technology such as JSP, ASP or PHP one or more times at a location such as a new application page or a newly popped up flybar.

Preferably, in step S301, the loading amount determining device 1 matches the query in the loading database according to the building selected by the user, and determines the loading amount of the photovoltaic power generation system that can be loaded in the building.

Specifically, the user selects a corresponding building through interaction with the user device, for example, in a mobile application of the mobile device or in a web page on the web side, for example, the name of the building is input in an input box of the mobile application or the web page, or a certain building is clicked in a satellite map presented by the mobile application or the web page; in step S301, the machine-loading amount determination device 1 directly matches and queries, according to the building selected by the user, a machine-loading amount of the loadable photovoltaic power generation system corresponding to the building selected by the user, for example, by storing the machine-loading amount of the loadable photovoltaic power generation system corresponding to each building in a machine-loading database.

Specifically, in sub-step S301a, the machine-loading amount determination apparatus 1 determines the current location of the user, for example, by calling a location means such as GPS or the like that is owned by the user equipment used by the user; or, the user equipment may call a positioning device such as a GPS thereon to obtain its own current position, and then actively send the current position to the loading amount determining device 1, where in sub-step S301a, the loading amount determining device 1 obtains the current position of the user equipment; subsequently, the loading amount determination device 1 determines in which building the user is currently located based on the current location of the user, and matches a query in a building database in which, for example, the areas to be loaded corresponding to the respective buildings are stored according to the name or longitude and latitude information of the building, thereby determining the areas to be loaded of the building.

Or, the user inputs a building search keyword in an input box of a web page at a mobile application or a PC end of the mobile device, for example, the input box inputs all or part of a name, longitude and latitude information, description information, or uploads a picture of a building, and in sub-step S301a, the loading amount determining apparatus 1 obtains the building search keyword input by the user, and directly performs a matching query in a building database based on the building search keyword, or determines a building to be searched by the user in a mode of picture recognition, information matching, and the like, and then performs a matching query in the building database, where, for example, the building database stores the loading areas corresponding to the buildings, thereby determining the loading areas.

Or, the user performs a certain framing operation in a satellite map provided by a mobile application of the mobile device or a web page at the PC end, for example, by framing a plurality of points in the satellite map so that the plurality of points form a framed area, or by dividing a plurality of lines in the satellite map to form a framed area; in sub-step S301a, the loading amount determining apparatus 1 may determine the loading waiting area based on the frame selection operation performed by the user in the map.

More preferably, in sub-step S301a, the loading amount determining apparatus 1 further determines a plurality of corresponding marker points based on a frame selection operation performed by the user in a map corresponding to the building; and determining the area to be loaded according to the longitude and latitude information of the plurality of marking points.

Specifically, the user performs a certain framing operation on the map corresponding to the building, the framing operation includes, but is not limited to, a clicking operation, a circling operation, a line drawing operation, and the like, the framing operation may have corresponding marked points, and in sub-step S301a, the loading amount determination apparatus 1 determines a plurality of corresponding marked points based on the framing operation performed on the map by the user. For example, for the clicking operation, in sub-step S301a, the machine-loading amount determination apparatus 1 may directly take several points clicked by the user as mark points; for the circle drawing operation, in sub-step S301a, the loading amount determining apparatus 1 may define several mark points from the circle drawn by the user, where the number of the defined mark points may be adjusted according to the size of the circle drawn by the user, where the circle drawn by the user may be a circle such as a perfect circle, an ellipse, or other irregular circle or polygon; for the line drawing operation, the user forms a framed area by drawing a plurality of lines in the satellite map, and in sub-step S301a, the loading amount determination apparatus 1 may use, for example, a point where the plurality of lines intersect as a marking point. Subsequently, in sub-step S301a, the loading amount determining apparatus 1 determines the to-be-loaded area corresponding to the frame selection operation of the user through conversion calculation according to the latitude and longitude information of each mark point.

Here, for the frame selection operations of the user, trigger conditions of the start and the end of the frame selection operation may be defined by the system or the user, for example, a "start" button and a "end" button may be provided in an interface of the mobile application, and when the user clicks the "start", the user may frame the region to be loaded on a satellite map displayed by the mobile application, for example, the user clicks a plurality of points on the satellite map, and then, the user may click the "end" button, that is, the user is considered to complete the selection of the region to be loaded, and in sub-step S301a, the loading amount determination apparatus 1 immediately determines the region to be loaded corresponding to the user' S frame selection operation according to the longitude and latitude information of the plurality of points. Alternatively, the system may define that when the user completes drawing a closed figure, that is, when the user performs a circling operation to close the corresponding figure, the selection of the region to be mounted is considered to be completed, and the closed figure may be a perfect circle, an ellipse, or another irregular circle or polygon, and in sub-step S301a, the mounting amount determining apparatus 1 then determines the region to be mounted corresponding to the circling operation of the user according to the closed figure.

More preferably, in sub-step S301a, the boarding amount determination apparatus 1 obtains a candidate area corresponding to the building according to the building selected by the user; and preprocessing the candidate area, and taking the preprocessed candidate area as the area to be loaded.

Specifically, since there may be some areas on the roof of the building where the photovoltaic power generation system cannot be loaded, such as a chimney, a water tank, and the like, it is necessary to delete the areas where the photovoltaic power generation system cannot be loaded, that is, the areas corresponding to the areas where the photovoltaic power generation system cannot be loaded cannot be used to calculate the loading amount of the loadable photovoltaic power generation system. When the user selects a certain building or performs a certain framing operation, in sub-step S301a, the loading amount determining apparatus 1 obtains a corresponding candidate area according to the building selected by the user or the framing operation performed by the user, where the candidate area refers to the whole roof area of the building or the area framed by the user; subsequently, in sub-step S301a, the loading amount determining apparatus 1 further performs preprocessing on the candidate area, for example, preprocessing a satellite image corresponding to the candidate area by image recognition, and since the general color of obstacles such as a chimney and a water tank is deeper than other open places on the roof, the candidate area, that is, the area occupied by the chimney and the water tank in the area selected by the user or the roof of the building can be removed by image color algorithm recognition, and the preprocessed candidate area is taken as the area to be loaded, so as to calculate the loading amount of the loadable photovoltaic power generation system.

Here, for the same building, the machine loading amount determining device 1 may perform processing such as screening and weighted calculation on different machine loading areas based on predetermined conditions, for example, directly delete data that is significantly different from the areas of the machine loading areas uploaded by other users, average the screened data to be the machine loading areas of the building, or assign corresponding weight values to the machine loading areas uploaded by different users based on credit ratings of different users, thereby performing weighted calculation on the machine loading areas to obtain the machine loading areas of the building, and further store the machine loading areas into the building database to establish or update the building database.

In this case, different auxiliary information may result in different loading amounts of the photovoltaic power generation system, for example, for a loading-standby area with a sunny weather, the loading amount of the photovoltaic power generation system is larger than for a loading-standby area with a rainy weather.

Preferably, the method further comprises step S304 (not shown).
