[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment Please refer to Figures 1 to 3 , the present invention provides a technical solution for a power energy monitoring and control method and system based on a smart building: A power energy monitoring and control method based on a smart building includes the following steps: S1: Divide the building area into multiple monitoring areas, deploy multiple first monitoring points corresponding to the multiple monitoring areas, and collect the load information of each monitoring area based on the multiple first monitoring points; deploy a second monitoring point for the energy storage device, and collect the reserved electric energy of the building area based on the second monitoring point. The steps of collecting all the load information of the monitoring area based on the first monitoring point include: obtaining each load device in the monitoring area, classifying the load devices to obtain the device levels; collecting the load information corresponding to multiple load devices in the monitoring area based on all the first monitoring points and packing them into a load information packet, taking the device level as the level of the load information packet, differentially marking different levels of load information packets, and sorting each load information packet in descending order of level.

[0020] Specifically, the load information includes but is not limited to the current power value of the device, the voltage fluctuation situation, and the current change trend; integrate and pack the load information of the same load device or multiple load devices in the same time period to generate the corresponding load information packet; when classifying the load devices, comprehensively consider multiple factors such as the criticality of the load device in the operation of the power system, the impact on power supply stability, the power consumption scale, and the importance level of the business undertaken, assign corresponding weights to each factor, obtain the comprehensive score of the load device through weighted calculation, perform level classification according to the comprehensive score, and perform level marking on the load information packet corresponding to the load device according to the obtained load device level. The level marking method can adopt digital coding, letter identification, or other distinguishable identification forms, so that the level of each load information packet corresponds to the level of the load device that generates the load information packet, so that in the subsequent processing and transmission process, differential processing and priority scheduling can be performed according to the level of the load information packet; the acquisition devices used at the monitoring points include but are not limited to power sensors, voltage sensors, and current sensors. The monitoring points collect data according to the preset sampling frequency and acquisition period. The sampling frequency is set according to the characteristics of the load device and the monitoring requirements, and the acquisition period can be dynamically adjusted according to the actual situation.

[0021] S2: Register monitoring terminals based on the first monitoring point and the second monitoring point respectively, and establish a communication channel between each monitoring terminal and the cloud server. Among them, the communication channel includes a first communication channel and a second communication channel; transmit multiple load information to the cloud server based on the first communication channel. Among them, there are multiple sub-channels in the first communication channel with the same number as the load devices in the monitoring area; transmit the reserved electric energy to the cloud server based on the second communication channel. The steps of registering monitoring terminals based on the first monitoring point and the second monitoring point respectively and establishing a communication channel between each monitoring terminal and the cloud server include: The cloud server includes multiple sub-databases, and each sub-database corresponds to a monitoring terminal. Establish a communication channel between each sub-database and the corresponding monitoring terminal, use the communication channel between the monitoring terminal corresponding to the first monitoring point and the sub-database as the first communication channel, and use the communication channel between the monitoring terminal corresponding to the second monitoring point and the sub-database as the second communication channel; Obtain the number of load devices in the monitoring area, and set the same number of sub-channels inside the first communication channel according to a preset arrangement method.

[0022] Specifically, the preset arrangement method can be set in a circular arrangement or other forms of arrangement, but the arrangement method needs to be consistent with the arrangement method of the subsequent load information packets around the time point, so that when multiple load devices are newly added during the peak electricity consumption period in the building area, it is convenient to randomly disperse the load information packets corresponding to the load devices into the corresponding sub-channels, relieve the transmission volume of the communication channel, and thus improve the efficiency of the cloud server in responding to newly added load devices.

[0023] Transmit multiple load information to the cloud server based on the first communication channel, where multiple sub-channels with the same number as the load devices in the monitoring area are set inside the first communication channel; The steps of transmitting the reserve electric energy to the cloud server based on the second communication channel include: Collect the reserve electric energy information corresponding to the building area based on the second monitoring point, and transmit the reserve electric energy information to the corresponding sub-database based on the second communication channel; Obtain each load information packet collected at the same collection time point, set the same number of virtual spheres as the number of collection time points, layout multiple load information packets around the virtual spheres, establish connection lines between the virtual spheres and the load information packets, and generate a main information packet containing multiple load information packets at this collection time point; Determine the time stamp according to the collection time point corresponding to each main information packet, and sort the generated main information packets corresponding to different time stamps in the order of collection time; Transmit multiple main information packets to the corresponding sub-databases in sequence based on the first communication channel.

[0024] Specifically, bind each load information packet collected at the same collection time point to generate a main information packet containing multiple load information packets at this collection time point. When collecting load information, record the collection time of each load information packet. For all the load information packets collected at the same collection time point, associate and integrate them 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 arrange the load information packets around the time point, and there are connection lines set between the time point and each load information packet. The connection lines are virtual connection lines that can realize the association between the time point and the load information packet at the logical level and are used to identify the time information corresponding to the load information packet. The arrangement of the load information packets around the time point is the same as the arrangement of the sub-channels inside the communication channel. The connection lines are used to connect the time point and multiple load information packets. The load information packets are arranged around the time point. The load information packets connected at the same time point through the connection lines are randomly scattered on each sub-channel and transmitted synchronously. One end of the connection line is fixed at the time point, and the other end is connected to the load information packet. The connection line can automatically expand and contract according to the relationship between the load information packet and the main information packet. When the load information packet detaches from the main information packet, the connection line automatically extends. When the load information packet is combined into 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 clearly understand through which sub-channel each load information packet is transmitted. During 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 on the time point, the load information packet can be positioned to determine from which position on the time point the load information packet is split, which is convenient for the subsequent recombination between multiple load information packets. For each main information packet, determine the time stamp according to its corresponding collection time point. The time stamp is used to identify the collection moment of each load information packet in the main information packet. Establish a main information packet queue and deposit the main information packets into the queue in sequence according to the order of the time stamps. During transmission, take out the main information packets from the head of the queue in sequence for transmission to ensure that the main information packets collected first are transmitted first to maintain the continuity and integrity of the load information in the time dimension.

[0025] The steps of laying out multiple load information packets around a virtual sphere, establishing connection lines between the virtual sphere and the load information packets, and generating a main information packet containing multiple load information packets at the acquisition time point include: laying out multiple load information packets around the virtual sphere and marking the positions of the load information packets on the virtual sphere; selecting a center point from the marked positions on the virtual sphere, establishing connection lines between the center point and the load information packets, and binding the multiple load information packets to the virtual sphere based on the multiple connection lines to obtain the main information packet corresponding to the acquisition time point. The main information packet contains multiple load information packets and the virtual sphere at the acquisition time point corresponding to the load information packets. It should be noted that a unique identifier is set for the position of each load information packet on the virtual sphere, and the unique identifier is used for marking, which is convenient for subsequently determining the position of the load information packet on the virtual sphere according to the connection line connecting the load information packets. The virtual sphere here is equivalent to a virtual sphere set for the corresponding acquisition time point, that is, it is equivalent to multiple load information packets being attached to the virtual sphere. Each main information packet contains a virtual sphere, and one virtual sphere corresponds to one acquisition time point.

[0026] Specifically, when marking the virtual sphere, regional division is carried out according to the positions where the load information packets are located, and the virtual sphere is divided into quadrant regions with the same number as the load information packets. One quadrant region corresponds to one load information packet respectively. The load information packets located in different regions are respectively positioned on the corresponding quadrant regions by connection lines. When the main information packet needs to be split and distributed to different sub-channels for transmission to meet the dispersion condition, it can be reasonably distributed to each sub-channel according to the position and connection relationship of the load information packets on the virtual sphere. For example, according to different regions on the virtual sphere or the direction of the connection lines, the load information packets are dispersed to multiple sub-channels to avoid excessive transmission pressure on a certain sub-channel and improve the overall transmission efficiency. During the transmission process, if data loss or errors occur, the structure of the virtual sphere and the connection lines helps to quickly detect and locate the problems. Since each load information packet is associated with the virtual sphere through a connection line, when there are problems with the data transmitted by a certain sub-channel, it is possible to determine which part of the lost or incorrect data belongs to according to the structure and connection relationship of the virtual sphere, and take corresponding recovery measures. Based on the marked positions of the load information packets on the virtual sphere and the connection lines, it is possible to accurately identify the original main information packet to which each load information packet belongs and its relative position in the original main information packet, thus realizing data reorganization.

[0027] The steps of sequentially transmitting multiple main information packets to corresponding sub-databases based on a first communication channel include: obtaining the positions of each load information packet on the main information packet and marking them to obtain position information; presetting a dispersion condition, and splitting the main information packets that meet the preset dispersion condition according to a dispersion rule to obtain multiple load information packets; randomly allocating the multiple load information packets to sub-channels, and transmitting each load information packet to the same sub-database based on the sub-channels; after the transmission is completed, determining the relative positions of each load information packet on the virtual sphere and the original virtual sphere to which each load information packet belongs based on the connection line, recombining the load information packets transmitted by each sub-channel, and restoring them into the original main information packet; directly transmitting the main information packets that do not meet the preset dispersion condition to the corresponding sub-databases via the first communication channel.

[0028] It should be noted that the dispersion rule means that at first, multiple load information packets are used as the packaging rule around a time point, and the reverse operation of the packaging rule is used as the 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 splitting are exactly the same as the load information packets that initially formed the main information packet. For example, at first, load information packet A, load information packet B, and load information packet C are formed into a main information packet around time point T. Splitting load information packet A, load information packet B, and load information packet C from time point T is used as the dispersion rule. The dispersion rule is the opposite of the process of generating the main information packet. Specifically, preset the dispersion condition. The dispersion condition includes but is not limited to that the data volume of the main information packet exceeds a preset threshold, and the load information type included in the main information packet belongs to a specific high-priority or complex type; when it is monitored that the main information packet exceeds the preset condition, the main information packet is dispersed, and the main information packet is split into multiple load information packets. The load information packets are interrelated in content and jointly constitute the complete information of the original main information packet; subsequently, according to the preset dispersion strategy, the split sub-information packets are randomly or dispersed to each sub-channel according to a specific rule. During the transmission process, the connection line always connects the load information packet to the corresponding virtual sphere. Through the connection line, the logical relationship between the load information packet and the center point of the virtual sphere can be determined, so as to correctly place the load information packet back to its original position on the virtual sphere and restore the structure of the main information packet. Thus, it can be ensured that the transmitted data is at the same acquisition time point, and it can also be ensured that each load information packet can be synchronously transmitted in each sub-channel. The pressure on the first communication channel is relieved through multiple sub-channels, thereby improving the transmission efficiency of the load information corresponding to each load device; it can efficiently and accurately organize multiple load information packets into a main information packet, and reasonably split and allocate the transmission according to the actual situation. While ensuring the integrity and accuracy of the data, the transmission resources of the sub-channels are fully utilized, and the data transmission efficiency is improved.

[0029] S3: Obtain the load information and reserve electric energy in the cloud server, predict the required electric energy in the monitoring area based on the load information, allocate the reserve electric energy based on multiple required electric energies, and control the destination of the electric energy according to the allocation result; The steps of predicting the required electric energy in the monitoring area based on the load information and allocating the reserve electric energy based on multiple required electric energies include: obtaining the monitoring end corresponding to the reserve electric energy as the electric energy monitoring end, and extracting the reserve electric energy information from the sub-database corresponding to the electric energy monitoring end to obtain the total reserve electric energy; obtaining the monitoring end corresponding to the monitoring area, and extracting the main information packet corresponding to the monitoring area from the sub-database corresponding to the monitoring end, where the main information packet includes the number of load information packets and the load information corresponding to each load information packet, and the load information includes the load device power and the expected operation duration of the device in the monitoring area at the same acquisition time point; predicting the required electric energy of each monitoring area based on multiple main information packets and performing comprehensive calculation to obtain the required electric energy of the building area; determining whether the required electric energy of the building area exceeds the total reserve electric energy; extracting the multiple main information packets corresponding to the required electric energy of the building area that exceeds the total reserve electric energy, removing the load information of the load devices corresponding to the lowest-level load information packets in each main information packet to obtain the processed main information packet, predicting the required electric energy of each monitoring area again based on the processed main information packet and performing comprehensive calculation to obtain the required electric energy of the building area, and continuing to execute the step of "determining whether the required electric energy of the building area exceeds the total reserve electric energy" until the required electric energy of the building area does not exceed the total reserve electric energy; obtaining the required electric energies of multiple monitoring areas corresponding to the required electric energy of the building area that does not exceed the total reserve electric energy, and allocating the total reserve electric energy based on the required electric energies of multiple monitoring areas.

[0030] It should be noted that the number of load information packets corresponds to the number of load devices. Here, the load devices refer to the electrical equipment that accesses the power supply to use electric energy. Electrical equipment that is not powered on is not counted, but when the electrical equipment accesses the power supply, it belongs to the load device; the load device power refers to the actual operating power of the electrical equipment after it is powered on. The formula for predicting the required electric energy in the monitoring area based on the main information packet is: , where represents the predicted required electric energy of the th monitoring area, represents the power consumption of the th load device in the monitoring area, represents the th expected operation duration of the load device, where the expected operation duration can be determined according to the average value of the historical operation duration within the period, represents the numbers of each load device in the monitoring area, represents the total number of load devices in the monitored area; the formula for comprehensively calculating the required electric energy of the building area by integrating the required electric energies of multiple monitored areas is: , where represents the required electric energy of the building area, represents the total number of monitored areas in the building area, represents the number of each monitored area in the building area, represents the th weight corresponding to the monitored area.

[0031] The steps of controlling the destination of electric energy according to the allocation result include: obtaining the required electric energy of each monitored area, and transferring the electric energy corresponding to the required electric energy from the reserved electric energy to the corresponding monitored area; determining the load device corresponding to the required electric energy in the monitored area based on the main information packet as the destination device of the electric energy; controlling the destination of the electric energy based on the destination device of the electric energy; Specifically, according to the total amount of reserved electric energy collected by the cloud server and the predicted required electric energy of the building area, the amount of electric energy to be delivered to each monitored area is controlled. When the total amount of reserved electric energy is limited, the load information corresponding to the load devices with higher levels can be automatically screened according to the levels of the load devices in each monitored area, and only the load information of the load devices with higher levels is calculated, and the load devices with the lowest level are excluded layer by layer, so as to ensure that the load devices with higher levels in each monitored area can operate normally, dynamically allocate and regulate the limited reserved electric energy, ensure the rationality and reliability of the electric energy supply, determine the load device corresponding to the required electric energy based on the main information packet as the destination device of the electric energy, and control it, which can realize the refined management of the destination of the electric energy and further improve the use efficiency and safety of the electric energy.

[0032] The electric energy monitoring and control system based on the intelligent building is applied to the electric energy monitoring and control method based on the intelligent building as described in any one of the above, and includes: An information monitoring module, which is used to divide the building area into multiple monitored areas, set up multiple first monitoring points corresponding to the multiple monitored areas, and collect the load information of each monitored area based on the multiple first monitoring points; set up a second monitoring point for the energy storage device, and collect the reserved electric energy of the building area based on the second monitoring point; An information transmission module, configured to register monitoring terminals based on a first monitoring point and a second monitoring point respectively, and establish communication channels between each monitoring terminal and a cloud server, wherein the communication channels include a first communication channel and a second communication channel; transmit a plurality of load information to the cloud server based on the first communication channel, wherein a plurality of sub-channels are arranged inside the first communication channel, and the number of sub-channels is the same as the number of load devices in the monitoring area; transmit reserve electric energy to the cloud server based on the second communication channel; A distribution control module, configured to obtain the load information and reserve electric energy in the cloud server, predict the required electric energy of the monitoring area based on the load information, distribute the reserve electric energy based on a plurality of required electric energies, and control the destination of the electric energy according to the distribution result.

[0033] In the present invention, by setting a plurality of sub-channels with the same number as the load devices, the load information packets at the same acquisition time point are arranged around a virtual sphere to generate a main information packet. The integrity and relevance of the load information packets are ensured through connection lines. During the transmission process, the main information packet is split and randomly distributed to the sub-channels according to preset conditions, and then recombined into the original main information packet after the transmission is completed; it can effectively disperse the data transmission pressure, improve the response efficiency to the load devices in the building area, and thus improve the transmission efficiency of the load information in the building area; by classifying the load devices and marking and sorting the device levels as the levels of the load information packets, it is judged whether the required electric energy in the building area exceeds the total reserve electric energy. For the main information packets of the excess part, the load device information of the lowest-level load information packet is removed, and the required electric energy is predicted again until the required electric energy does not exceed the total reserve electric energy, realizing the dynamic and intelligent distribution of the reserve electric energy and ensuring the reasonable utilization of the electric energy.
