[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] Example

[0057] See also Figures 1 to 3 The present invention provides a method and system technical solution for monitoring and controlling electric energy based on smart buildings: The method for monitoring and controlling electric energy based on smart buildings comprises the following steps:

[0058] S1: Divide the building area into multiple monitoring areas, deploy multiple first monitoring points corresponding to the multiple monitoring areas, and collect load information for each monitoring area based on the multiple first monitoring points; deploy second monitoring points for the energy storage device, and collect reserve power in the building area based on the second monitoring points;

[0059] The steps of collecting all load information of the monitoring area based on the first monitoring point include: obtaining each load device in the monitoring area, and classifying the load equipment to obtain the equipment level; based on all the first monitoring points, collecting the load information corresponding to multiple load devices in the monitoring area and packaging them to generate load information packages, using the equipment level as the level of the load information package, distinguishing and marking load information packages of different levels, and sorting each load information package in descending order of level.

[0060] Specifically, load information includes, but is not limited to, the current power value of the device, voltage fluctuations, and current change trends. Load information for the same load device or multiple load devices in the same time period is integrated and packaged to generate corresponding load information packets. When grading load devices, multiple factors are comprehensively considered, including the criticality of the load device in the operation of the power system, the impact on power supply stability, the scale of power consumption, and the importance of the business undertaken. A corresponding weight is assigned to each factor, and a comprehensive score of the load device is obtained through weighted calculation. The load device is graded based on the comprehensive score. Based on the obtained load device grade, the load information packet corresponding to the load device is graded. The grade marking method can use digital coding, alphabetical identification, or other distinctive identification forms, so that the grade of each load information packet corresponds to the grade of the load device that generated the load information packet. In the subsequent processing and transmission process, differentiated processing and priority scheduling can be performed based on the grade of the load information packet. The collection devices used at the monitoring point include, but are not limited to, power sensors, voltage sensors, and current sensors. The monitoring point collects data according to a preset sampling frequency and collection period. The sampling frequency is set according to the characteristics of the load device and monitoring requirements, and the collection period can be dynamically adjusted according to actual conditions.

[0061] S2: Registering monitoring terminals based on the first monitoring point and the second monitoring point, respectively, and establishing communication channels between each monitoring terminal and the cloud server, wherein the communication channels include a first communication channel and a second communication channel; transmitting multiple load information to the cloud server based on the first communication channel, wherein the first communication channel is internally provided with multiple sub-channels equal to the number of load devices in the monitoring area; and transmitting the reserved power to the cloud server based on the second communication channel;

[0062] The steps of registering monitoring terminals respectively based on the first monitoring point and the second monitoring point and establishing communication channels between each monitoring terminal and the cloud server include: the cloud server includes multiple sub-databases, the sub-databases correspond to the monitoring terminals one-to-one, and a communication channel is established between each sub-database and the corresponding monitoring terminal, and the communication channel between the monitoring terminal corresponding to the first monitoring point and the sub-database is used as the first communication channel, and the communication channel between the monitoring terminal corresponding to the second monitoring point and the sub-database is used as the second communication channel; the number of load devices in the monitoring area is obtained, and the same number of sub-channels are set inside the first communication channel according to a preset arrangement.

[0063] Specifically, the preset arrangement method can be a circular arrangement or other forms of arrangement, but the arrangement method needs to be consistent with the arrangement method of subsequent load information packets around the time point. When multiple load devices are added at the same time during the peak electricity consumption period in the building area, the load information packets corresponding to the load devices can be randomly dispersed to the corresponding sub-channels, thereby alleviating the transmission volume of the communication channel and improving the efficiency of the cloud server in responding to the newly added load devices.

[0064] Based on the first communication channel, multiple load information is transmitted to the cloud server, wherein the first communication channel is internally provided with multiple sub-channels with the same number as the load equipment in the monitoring area; the step of transmitting the reserve power to the cloud server based on the second communication channel includes: collecting the reserve power information corresponding to the building area based on the second monitoring point, and transmitting the reserve power information to the corresponding sub-database based on the second communication channel; obtaining each load information packet collected at the same collection time point, setting the same number of virtual balls corresponding to the number of collection time points, arranging multiple load information packets around the virtual balls, establishing connecting lines between the virtual balls and the load information packets, and generating a main information packet containing multiple load information packets at the collection time point; determining the timestamp according to the collection time point corresponding to each main information packet, and sorting the main information packets corresponding to different timestamps according to the collection time sequence; and transmitting the multiple main information packets to the corresponding sub-database in sequence based on the first communication channel.

[0065] Specifically, the load information packets collected at the same collection time point are bound to generate a main information packet containing multiple load information packets at the collection time point. When collecting load information, the collection time of each load information packet is recorded. All load information packets collected at the same collection time point are associated and integrated through a preset data structure or identifier to form a main information packet containing complete collection time information and load data of each load device. The preset data structure or identifier is to surround the load information packet around the time point, and a connecting line is set between the time point and each load information packet. The connecting line is a virtual connecting line that can realize the association between the time point and the load information packet at the logical level and is used to identify the time information corresponding to the load information packet. The arrangement of the load information packet around the time point is consistent with the arrangement of the sub-channels within the communication channel. The connecting line is used to connect the time point with multiple load information packets. The load information packets surround the time point. The load information packets connected at the same time point through the connecting line are randomly scattered on each sub-channel and transmitted synchronously. One end of the connecting line is fixed at the time point, and the other end is connected to the load information packet. The connecting line can be used to connect the load information packet with the main information packet according to the time point. The relationship between information packets is automatically extended and retracted. When the load information packet is separated from the main information packet, the connection line automatically extends. When the load information packet is combined in the main information packet, the connection line automatically shortens. According to the connection line, it can be ensured that the combined multiple load information packets are dispersed from the same main information packet, and it can be ensured that each load information packet is transmitted synchronously in the corresponding sub-channel. It can also be clearly understood through which sub-channel each load information packet is transmitted. In the dispersed transmission, the connection line is always connected to the load information packet. At the same time, according to the position of the other end of the connection line at the time point, the load The information packet is located to determine the position at which the load information packet is split out, so as to facilitate the subsequent reorganization of multiple load information packets; for each main information packet, the timestamp is determined according to its corresponding collection time point. The timestamp is used to identify the collection moment of each load information packet in the main information packet, and a main information packet queue is established. The main information packets are stored in the queue in sequence according to the sequence of timestamps; during transmission, the main information packets are taken out from the head of the queue in sequence for transmission to ensure that the main information packets collected first are transmitted first, so as to maintain the continuity and integrity of the load information in the time dimension.

[0066] The steps of arranging multiple load information packets around a virtual ball, establishing connecting lines between the virtual ball and the load information packets, and generating a main information packet containing the multiple load information packets at the acquisition time point include: arranging the multiple load information packets around the virtual ball, marking the positions of the load information packets on the virtual ball; selecting a center point from the marked positions on the virtual ball, establishing connecting lines between the center point and the load information packets, and binding the multiple load information packets to the virtual ball based on the multiple connecting lines to obtain a main information packet corresponding to the acquisition time point, the main information packet containing the multiple load information packets and the virtual ball corresponding to the acquisition time point of the load information packets;

[0067] It should be noted that a unique identifier is set for the position of each load information packet on the virtual ball, and it is marked with a unique identifier to facilitate the subsequent determination of the position of the load information packet on the virtual ball based on the connecting line connecting the load information packet. The virtual ball here is equivalent to a virtual ball set corresponding to the collection time point, that is, it is equivalent to multiple load information packets being attached to the virtual ball. Each main information packet contains a virtual ball, and one virtual ball corresponds to one collection time point.

[0068] Specifically, when marking the virtual ball, the load information packets are divided into quadrants based on their locations. The virtual ball is divided into quadrants equal in number to the number of load information packets, with each quadrant corresponding to a load information packet. Load information packets located in different quadrants are then positioned on the corresponding quadrants using connecting lines. When a main information packet meets the dispersion criteria and needs to be split and distributed across different subchannels for transmission, the load information packets can be distributed to the subchannels based on their locations and connections on the virtual ball. For example, load information packets can be distributed across multiple subchannels based on the different regions or directions of the connecting lines on the virtual ball, thereby preventing excessive transmission pressure on any particular subchannel and improving overall transmission efficiency. If data loss or errors occur during transmission, the structure of the virtual ball and connecting lines facilitates rapid detection and location of the problem. Since each load information packet is associated with the virtual ball via connecting lines, if a problem occurs with the data transmitted by a particular subchannel, the structure and connections of the virtual ball can be used to determine which portion of the data is lost or erroneous, and appropriate recovery measures can be taken. Based on the marked positions and connecting lines of the load information packets on the virtual ball, the original main information packet to which each load information packet belongs and its relative position in the original main information packet can be accurately identified, thereby achieving data reorganization.

[0069] The steps of sequentially transmitting multiple main information packets to corresponding sub-databases based on the first communication channel include: obtaining the position of each load information packet on the main information packet and marking the position information; presetting a dispersion condition, and splitting the main information packet that meets the preset dispersion condition according to the dispersion rule to obtain multiple load information packets; randomly assigning the multiple load information packets to sub-channels, and transmitting each load information packet to the same sub-database based on the sub-channel; after the transmission is completed, determining the relative position of each load information packet on the virtual ball and the original virtual ball to which each load information packet belongs based on the connecting line, and recombining the load information packets transmitted by each sub-channel to restore them to the original main information packet; and directly transmitting the main information packets that do not meet the preset dispersion condition to the corresponding sub-database via the first communication channel.

[0070] It should be noted that the dispersion rule refers to the process of initially grouping multiple load information packets around a time point as a packing rule, and then reversing the packing rule to form a dispersion rule. That is, the process of splitting multiple load information packets from the main information packet is used as the dispersion rule. The multiple load information packets obtained after the splitting are completely consistent with the load information packets that originally constituted the main information packet. For example, initially, load information packets A, load information packet B, and load information packet C are grouped around time point T to form a main information packet. Then, load information packets A, load information packet B, and load information packet C are split from time point T. This is the dispersion rule, and the dispersion rule is the opposite of the process of generating the main information packet.

[0071] Specifically, a dispersion condition is preset, including but not limited to the data size of the main information packet exceeding a preset threshold and the type of load information contained in the main information packet being of a specific high priority or complex type. When it is detected that the main information packet exceeds the preset condition, the main information packet is dispersed to split the main information packet into multiple load information packets. The load information packets are mutually related in content and together constitute the complete information of the original main information packet. Subsequently, according to a preset dispersion strategy, the split sub-information packets are randomly or according to specific rules dispersed to each sub-channel. During the transmission process, the connecting line always connects the load information packet to the corresponding virtual sphere. The logical relationship between the load information packet and the center point of the virtual sphere can be determined through the connecting line, so that the load information packet is correctly placed back to its original position on the virtual sphere and the structure of the main information packet is restored. This ensures that the transmitted data is collected at the same time point and that each load information packet can be transmitted synchronously in each sub-channel. The pressure on the first communication channel is alleviated by multiple sub-channels, thereby improving the transmission efficiency of the load information corresponding to each load device. The multiple load information packets can be efficiently and accurately organized into a main information packet and reasonably split and distributed for transmission according to actual conditions. While ensuring data integrity and accuracy, it fully utilizes the transmission resources of the sub-channel and improves the efficiency of data transmission.

[0072] S3: Obtain load information and reserve power from the cloud server, predict the power demand in the monitoring area based on the load information, allocate reserve power based on multiple power demands, and control the flow of power according to the allocation results;

[0073] The steps of predicting the power demand of the monitoring area based on the load information and allocating the reserve power based on multiple power demand include: obtaining the monitoring end corresponding to the reserve power as the power monitoring end, extracting the reserve power information from the sub-database corresponding to the power monitoring end to obtain the total reserve power; obtaining the monitoring end corresponding to the monitoring area, extracting the main information package corresponding to the monitoring area from the sub-database corresponding to the monitoring end, wherein the main information package includes the number of load information packages and the load information corresponding to each load information package, and the load information includes the power of the load equipment in the monitoring area at the same collection time point and the expected operating time of the equipment; predicting the power demand of each monitoring area based on multiple main information packages and performing comprehensive calculation to obtain the power demand of the building area; judging the building area whether the power demand of the building area exceeds the total reserve power; extracting multiple main information packets corresponding to the power demand of the building area that exceeds the total reserve power, removing the load information of the load equipment corresponding to the lowest-level load information packet in each main information packet, obtaining a processed main information packet, re-predicting the power demand of each monitoring area based on the processed main information packet and performing a comprehensive calculation to obtain the power demand of the building area, continuing to execute the step of "determining whether the power demand of the building area exceeds the total reserve power" until the power demand of the building area does not exceed the total reserve power; obtaining the power demand of multiple monitoring areas corresponding to the power demand of the building area that does not exceed the total reserve power, and allocating the total reserve power based on the power demand of the multiple monitoring areas.

[0074] It should be noted that the number of load information packets corresponds to the number of load devices. Load devices here refer to electrical devices that are connected to a power source and use electricity. Electrical devices that are not powered are not counted. However, when electrical devices are connected to a power source, they are considered load devices. Load device power refers to the actual operating power of the electrical device after it is connected to a power source. The formula corresponding to the power demand of the monitoring area predicted based on the main information packet is: ,in, Indicates the The predicted power demand of each monitoring area, Indicates the monitoring area The power consumption of each load device, Indicates the The expected operating time of each load device, where the expected operating time can be determined based on the average value of the historical operating time within the period. Indicates the number of each load device in the monitoring area. Represents the total number of load devices in the monitoring area; the formula for calculating the power demand of the building area by comprehensively calculating the power demand of multiple monitoring areas is: ,in, Indicates the required electrical energy of the building area, represents the total number of monitoring areas in the building area, Indicates the number of each monitoring area in the building area, Indicates the The weight corresponding to each monitoring area.

[0075] The steps of controlling the destination of electric energy according to the allocation result include: obtaining the electric energy demand of each monitoring area, transferring electric energy corresponding to the electric energy demand from the electric energy reserve to the corresponding monitoring area; determining the load device corresponding to the electric energy demand in the monitoring area based on the main information packet as the destination device of the electric energy; and controlling the destination of the electric energy based on the destination device of the electric energy;

[0076] Specifically, based on the total amount of reserve electric energy collected by the cloud server and the predicted demand electric energy of the building area, the amount of electric energy that needs to be delivered to each monitoring area is controlled. When the total amount of reserve electric energy is limited, the load information corresponding to the high-level load equipment can be automatically filtered out according to the level of the load equipment in each monitoring area. Only the load information of the high-level load equipment is calculated, and the load equipment of the lowest level is eliminated layer by layer, so as to ensure that the high-level load equipment in each monitoring area can operate normally, and the limited reserve electric energy is dynamically allocated and regulated to ensure the rationality and reliability of the electric energy supply. The load equipment corresponding to the demand electric energy is determined according to the main information package as the destination equipment of the electric energy, and is controlled, which can realize the refined management of the destination of the electric energy and further improve the efficiency and safety of the use of electric energy.
