Detailed Description
In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
Fig. 1 shows a flowchart of a smart home electricity monitoring method of the present invention.
As shown in fig. 1, the invention discloses a method for monitoring electricity consumption of an intelligent home, which comprises the following steps:
s102, analyzing according to a total actual power curve of the electricity consumption area and a total simulated power curve of the electric equipment of the electricity consumption area to obtain first curve similar data;
S104, when the first curve similar data is larger than a first preset threshold value, judging that abnormal equipment exists in the current electric equipment;
s106, subtracting the total actual power curve and the total simulated power curve to obtain a first difference power curve;
s108, analyzing the simulated power curve of each electric equipment based on the first difference power curve, and determining second curve similar data of the simulated power curve of each electric equipment;
s110, carrying out exception verification on each electric equipment based on the second curve similar data, and determining exception equipment.
According to the embodiment of the invention, the total simulated power curve of the electric equipment in the electricity utilization area is obtained by prediction according to the historical use data of the electric equipment, the user preference and other parameters, so that a certain difference exists between the total simulated power curve and the actual power curve. Therefore, when the total actual power curve of the electricity utilization area and the total simulated power curve of the electric equipment of the electricity utilization area are compared, whether abnormal equipment exists in the current electricity utilization area is judged by calculating the curve similarity of the total actual power curve and the total simulated power curve of the electric equipment of the electricity utilization area.
In the case of abnormal electricity utilization of the electric equipment, the actual power curve of the electric equipment also has regular characteristics of the using parameters, for example, the actual power curve generated by the drum washing machine in the working state is related to the running state of the drum motor. Under the condition that the actual power curve obtained by the energy consumption monitoring module is abnormal, a first difference power curve formed according to the difference between the total actual power curve and the total analog power curve is added with each electric equipment, and a second analog power curve of each electric equipment is obtained. And then, calculating the curve similarity of the first simulated power curve and the second simulated power curve of each electric equipment by a system preset method, so as to determine the probability value of power abnormality of each electric equipment, namely second curve similarity data. And then sequentially carrying out abnormality verification on each electric equipment according to the sequence from the large to the small of the second curve similar data, comparing the difference value of the total actual power curve and the total analog power curve to determine abnormal equipment by sequentially powering off each electric equipment, and determining the actual power curve of the abnormal equipment. And under the condition that the total actual power curve is consistent with the total simulated power curve or the curve similarity is greater than a preset threshold value of the system, the simulated power curve of the electric equipment is the actual power curve.
Because the variable-frequency electric equipment has certain difference between the actual power curve and the simulated power curve in the actual working process, when the to-be-determined abnormal equipment is subjected to abnormal verification, on the basis of comparing whether the actual power curve and the simulated power curve are consistent, whether the to-be-determined abnormal equipment is the abnormal equipment or not is judged by calculating the similarity of the actual power curve and the simulated power curve, a corresponding threshold value is set through a system, and whether the similarity of the total actual power curve of the current area of the equipment and the total simulated power curve of the residual electric equipment is larger than the set threshold value is judged. If the power-off equipment is larger than the power-on equipment, the power-off equipment is abnormal equipment; otherwise, the device is a normal device.
According to an embodiment of the present invention, further comprising:
the total actual power curve is obtained through an energy consumption monitoring module;
analyzing according to environmental data and user preference in combination with historical use data of electric equipment, and carrying out simulation operation in combination with the working environment of each electric equipment to obtain a first simulation power curve of each electric equipment;
and accumulating the simulated power curves of all the electric equipment to obtain the total simulated power curve of the electric equipment in the electricity utilization area.
It should be noted that, the energy consumption monitoring module is configured to obtain real-time power of indoor power consumption, and may be set according to a power supply line, for example, set on a main power supply line of each room, so as to monitor power consumption conditions of smart home in each room, and reduce abnormal verification times when power consumption is abnormal.
The user preference can determine the use habit of the user on the current electric equipment, the historical use data of the current equipment is combined, and the working state of the current equipment is simulated by combining the working environment, so that the operation parameters of the current electric equipment in the working process and the power change curve in the working process, namely the first simulated power curve of the electric equipment, are determined. The working environment parameters of different electric equipment are different, for example, when the air conditioner is simulated, the indoor and outdoor initial temperatures and the indoor temperature changes are mainly simulated; when the washing machine is subjected to simulation work, the simulation is mainly performed based on the material and the type of clothes to be washed. Meanwhile, the first simulation power curve of the electric equipment is adjusted in real time according to the operation parameters of the electric equipment in the actual working process, and when the operation parameters of the electric equipment are changed, the first simulation power curve of the electric equipment is correspondingly adjusted.
According to an embodiment of the present invention, the analyzing the simulated power curve of each electric device based on the first difference power curve, determining second curve similarity data of the simulated power curve of each electric device, includes:
adding the first difference power curve with the analog power curve of each electric equipment to obtain a second analog power curve;
And respectively carrying out similarity calculation on the second analog power curve and the first analog power curve of each electric equipment to obtain second curve similarity data of the analog power curve of each electric equipment.
It should be noted that, similarity calculation is performed on the second analog power curve and the first analog power curve of the electric equipment through a similarity algorithm preset by the system, such as a cosine similarity algorithm, a pearson correlation coefficient algorithm, and the like, so as to determine curve similarity data between the second analog power curve and the first analog power curve of the electric equipment.
According to an embodiment of the present invention, the performing exception verification on each electric device based on the second curve similar data, and determining an exception device, includes:
selecting the electric equipment with the highest second curve similar data as undetermined abnormal equipment;
selecting a verification method according to the equipment grade of the undetermined abnormal equipment;
if the undetermined abnormal equipment is the first-level equipment, controlling other electric equipment to be powered off in sequence for auxiliary verification;
if the undetermined abnormal equipment is the second level equipment, directly performing power-off verification;
if the power-off verification device is abnormal, determining an actual power curve of the abnormal device according to a total actual power curve of the powered device after power off, a total simulated power curve of the residual powered device and a first simulated power curve of the abnormal device;
Adjusting the abnormal equipment according to the actual power curve of the abnormal equipment;
if the power-off verification device is normal, selecting the next electric equipment to perform abnormal verification according to the second curve similar data.
It should be noted that, the larger the curve similarity data between the second analog power curve and the first analog power curve of the electric device is, the larger the probability that the first difference power curve is generated for the electric device is. Therefore, in the process of carrying out abnormal verification on the electric equipment, the electric equipment with the highest second curve similar data is preferentially selected for carrying out abnormal verification. In the process of abnormal verification, different modes are selected for verification according to the equipment grade of the to-be-determined abnormal equipment, wherein the first grade equipment is electric equipment which cannot be interrupted in the working process, such as a television, a computer and the like, and auxiliary judgment is needed by judging the use states of other electric equipment; the second level equipment is electric equipment which can be interrupted in overload work, such as a washing machine, an air conditioner, a water heater and the like, and the electric equipment which can not influence the use effect when being powered off for a short time in the use process can be directly powered off for abnormal verification. The power-off time can be set according to actual use requirements.
In the power-off verification process of the electric equipment, if the total actual power curve is inconsistent with the total simulated power curve of the rest electric equipment or the curve similarity is smaller than a system preset threshold, the electric equipment which is verified by current power-off is not abnormal, and the verification of other electric equipment is continued. After the abnormal equipment is determined, comparing a second difference power curve obtained by subtracting the total actual power curve of the abnormal equipment from the total simulated power curve of the residual electric equipment with the first difference power curve to determine whether the current monitoring area (indoor) has abnormal electricity consumption conditions except the current abnormal equipment, and if not, determining the actual power curve of the current abnormal equipment through the second difference power curve and the simulated power curve of the current abnormal equipment; if the current abnormal equipment exists, determining an actual power curve of the current abnormal equipment according to the difference value of the first difference power curve and the second difference power curve and combining the simulated power curve of the current abnormal equipment.
FIG. 2 is a flow chart illustrating a method of auxiliary verification of a pending anomaly device of the present invention.
As shown in fig. 2, according to an embodiment of the present invention, if the pending abnormal device is a first level device, controlling other electric devices to power down in sequence to perform auxiliary verification includes:
S202, selecting one or more other electric equipment with second curve similar data larger than a second preset threshold value, and sorting in descending order according to the second curve similar data;
s204, selecting other electric equipment with the highest second curve similar data to perform power-off treatment;
s206, judging whether the total actual power curve is consistent with the total simulated power curve of the rest electric equipment after the other electric equipment is powered off;
s208, if the power consumption equipment is consistent with the power consumption equipment, the other power consumption equipment is normal equipment;
s210, if the power consumption equipment is inconsistent, the other power consumption equipment is abnormal equipment,
and S212, after all other electric equipment is verified and equipment parameters are adjusted, if the total actual power curve and the total simulated power curve are inconsistent, the undetermined abnormal equipment is abnormal equipment.
It should be noted that, when abnormal verification is performed on the first level device which cannot be powered off in the working process, auxiliary verification is required to be performed through other electric equipment. Because the second curve similar data represents the probability value generated by the current electric equipment by the first difference power curve, when the second curve similar data is smaller than certain data, the first difference power curve can be determined to be irrelevant to the current electric equipment. And sequentially carrying out power-off abnormality verification on each other electric equipment according to the size of the second curve similar data by selecting one or more other electric equipment with the second curve similar data larger than a second preset threshold, and if the total actual power curve of each other electric equipment after power off is consistent with the total simulated power curve of the rest electric equipment or the curve similarity is larger than a system preset threshold, indicating that the first difference power curve is generated by abnormal electric power of the current abnormal equipment, and the current abnormal equipment is abnormal equipment.
The second preset threshold value can be set according to actual use requirements by a person skilled in the art, and other electric equipment can be selected according to the preset number of the system.
FIG. 3 shows a flow chart of a method of power-down verification of a pending anomaly device of the present invention.
As shown in fig. 3, according to an embodiment of the present invention, if the pending abnormal device is a second level device, power-off verification is directly performed, including:
s302, judging whether the total actual power curve is consistent with the total simulated power curve of the residual electric equipment after the undetermined abnormal equipment is powered off;
s304, if the predetermined abnormal equipment is the same, the predetermined abnormal equipment is the abnormal equipment;
and S306, if the equipment is inconsistent, the equipment to be determined is normal equipment, and the next electric equipment is selected as the equipment to be determined to be abnormal according to the similar data size of the second curve to perform power-off verification until the equipment to be determined to be abnormal is determined.
It should be noted that, after the abnormal device is powered off, the total actual power of the current power consumption area should be the same as or similar to the total analog power of the remaining power consumption equipment, that is, the total actual power curve is consistent with the total analog power curve of the remaining power consumption equipment or the curve similarity is greater than the system preset threshold, and according to the second curve similarity data size, the power consumption equipment in the current power consumption area is sequentially determined as the to-be-determined abnormal device to perform power off abnormality detection, and the abnormal device in the current power consumption area is determined through the total actual power curve after each power off and the total analog power curve of the remaining power consumption equipment.
According to an embodiment of the present invention, the determining the actual power curve of the abnormal device according to the total actual power curve of the powered device after power failure, the total simulated power curve of the remaining powered device, and the first simulated power curve of the abnormal device includes:
subtracting the total actual power curve of the powered device after power failure from the total simulated power curve of the remaining powered device to obtain a second difference power curve;
judging whether the second difference power curve is consistent with the first difference power curve or not;
if the power curves are consistent, adding the second difference power curve and the first simulated power curve of the abnormal equipment to obtain an actual power curve of the abnormal equipment;

In this case, the electric equipment which is not subjected to the power-off verification is continuously detected based on the second difference power curve until the total actual power curve is consistent with the total simulated power curve of the rest electric equipment or the curve similarity is larger than the preset threshold value of the system.

For the first abnormal reason, a temperature sensor can be arranged in equipment which is easy to generate accumulated heat, the real-time temperature of the equipment is detected through the temperature sensor, the equipment is started and stopped for management, when the internal temperature of the equipment meets the overheat condition of the equipment, the equipment is stopped for heat dissipation, and when the internal temperature of the equipment is reduced to the preset temperature of the system, the equipment continues to work.

Fig. 4 shows a block diagram of an intelligent household electricity monitoring system of the present invention.
As shown in fig. 4, a second aspect of the present invention provides an intelligent household electricity monitoring system, including:
the curve similarity calculation module is used for analyzing according to the total actual power curve of the electricity utilization area and the total simulated power curve of the electric equipment of the electricity utilization area to obtain first curve similarity data;
the abnormality detection module is used for judging that abnormal equipment exists in the current electric equipment when the first curve similar data is larger than a first preset threshold value;
the abnormality verification module is used for subtracting the total actual power curve and the total simulated power curve to obtain a first difference power curve; analyzing the simulated power curve of each electric equipment based on the first difference power curve, and determining second curve similar data of the simulated power curve of each electric equipment; and carrying out abnormal verification on each electric equipment based on the second curve similar data, and determining abnormal equipment.
According to the embodiment of the invention, the total simulated power curve of the electric equipment in the electricity utilization area is obtained by prediction according to the historical use data of the electric equipment, the user preference and other parameters, so that a certain difference exists between the total simulated power curve and the actual power curve. Therefore, when the total actual power curve of the electricity utilization area and the total simulated power curve of the electric equipment of the electricity utilization area are compared, whether abnormal equipment exists in the current electricity utilization area is judged by calculating the curve similarity of the total actual power curve and the total simulated power curve of the electric equipment of the electricity utilization area.
In the case of abnormal electricity utilization of the electric equipment, the actual power curve of the electric equipment also has regular characteristics of the using parameters, for example, the actual power curve generated by the drum washing machine in the working state is related to the running state of the drum motor. Under the condition that the actual power curve obtained by the energy consumption monitoring module is abnormal, a first difference power curve formed according to the difference between the total actual power curve and the total analog power curve is added with each electric equipment, and a second analog power curve of each electric equipment is obtained. And then, calculating the curve similarity of the first simulated power curve and the second simulated power curve of each electric equipment by a system preset method, so as to determine the probability value of power abnormality of each electric equipment, namely second curve similarity data. And then sequentially carrying out abnormality verification on each electric equipment according to the sequence from the large to the small of the second curve similar data, comparing the difference value of the total actual power curve and the total analog power curve to determine abnormal equipment by sequentially powering off each electric equipment, and determining the actual power curve of the abnormal equipment. And under the condition that the total actual power curve is consistent with the total simulated power curve or the curve similarity is greater than a preset threshold value of the system, the simulated power curve of the electric equipment is the actual power curve.
Because the variable-frequency electric equipment has certain difference between the actual power curve and the simulated power curve in the actual working process, when the to-be-determined abnormal equipment is subjected to abnormal verification, on the basis of comparing whether the actual power curve and the simulated power curve are consistent, whether the to-be-determined abnormal equipment is the abnormal equipment or not is judged by calculating the similarity of the actual power curve and the simulated power curve, a corresponding threshold value is set through a system, and whether the similarity of the total actual power curve of the current area of the equipment and the total simulated power curve of the residual electric equipment is larger than the set threshold value is judged. If the power-off equipment is larger than the power-on equipment, the power-off equipment is abnormal equipment; otherwise, the device is a normal device.
According to an embodiment of the present invention, further comprising:
the total actual power curve is obtained through an energy consumption monitoring module;
analyzing according to environmental data and user preference in combination with historical use data of electric equipment, and carrying out simulation operation in combination with the working environment of each electric equipment to obtain a first simulation power curve of each electric equipment;
and accumulating the simulated power curves of all the electric equipment to obtain the total simulated power curve of the electric equipment in the electricity utilization area.
It should be noted that, the energy consumption monitoring module is configured to obtain real-time power of indoor power consumption, and may be set according to a power supply line, for example, set on a main power supply line of each room, so as to monitor power consumption conditions of smart home in each room, and reduce abnormal verification times when power consumption is abnormal.
The user preference can determine the use habit of the user on the current electric equipment, the historical use data of the current equipment is combined, and the working state of the current equipment is simulated by combining the working environment, so that the operation parameters of the current electric equipment in the working process and the power change curve in the working process, namely the first simulated power curve of the electric equipment, are determined. The working environment parameters of different electric equipment are different, for example, when the air conditioner is simulated, the indoor and outdoor initial temperatures and the indoor temperature changes are mainly simulated; when the washing machine is subjected to simulation work, the simulation is mainly performed based on the material and the type of clothes to be washed. Meanwhile, the first simulation power curve of the electric equipment is adjusted in real time according to the operation parameters of the electric equipment in the actual working process, and when the operation parameters of the electric equipment are changed, the first simulation power curve of the electric equipment is correspondingly adjusted.
According to an embodiment of the present invention, the analyzing the simulated power curve of each electric device based on the first difference power curve, determining second curve similarity data of the simulated power curve of each electric device, includes:
adding the first difference power curve with the analog power curve of each electric equipment to obtain a second analog power curve;
And respectively carrying out similarity calculation on the second analog power curve and the first analog power curve of each electric equipment to obtain second curve similarity data of the analog power curve of each electric equipment.
It should be noted that, similarity calculation is performed on the second analog power curve and the first analog power curve of the electric equipment through a similarity algorithm preset by the system, such as a cosine similarity algorithm, a pearson correlation coefficient algorithm, and the like, so as to determine curve similarity data between the second analog power curve and the first analog power curve of the electric equipment.
According to an embodiment of the present invention, the performing exception verification on each electric device based on the second curve similar data, and determining an exception device, includes:
selecting the electric equipment with the highest second curve similar data as undetermined abnormal equipment;
selecting a verification method according to the equipment grade of the undetermined abnormal equipment;
if the undetermined abnormal equipment is the first-level equipment, controlling other electric equipment to be powered off in sequence for auxiliary verification;
if the undetermined abnormal equipment is the second level equipment, directly performing power-off verification;
if the power-off verification device is abnormal, determining an actual power curve of the abnormal device according to a total actual power curve of the powered device after power off, a total simulated power curve of the residual powered device and a first simulated power curve of the abnormal device;
Adjusting the abnormal equipment according to the actual power curve of the abnormal equipment;
if the power-off verification device is normal, selecting the next electric equipment to perform abnormal verification according to the second curve similar data.
It should be noted that, the larger the curve similarity data between the second analog power curve and the first analog power curve of the electric device is, the larger the probability that the first difference power curve is generated for the electric device is. Therefore, in the process of carrying out abnormal verification on the electric equipment, the electric equipment with the highest second curve similar data is preferentially selected for carrying out abnormal verification. In the process of abnormal verification, different modes are selected for verification according to the equipment grade of the to-be-determined abnormal equipment, wherein the first grade equipment is electric equipment which cannot be interrupted in the working process, such as a television, a computer and the like, and auxiliary judgment is needed by judging the use states of other electric equipment; the second level equipment is electric equipment which can be interrupted in overload work, such as a washing machine, an air conditioner, a water heater and the like, and the electric equipment which can not influence the use effect when being powered off for a short time in the use process can be directly powered off for abnormal verification. The power-off time can be set according to actual use requirements.
In the power-off verification process of the electric equipment, if the total actual power curve is inconsistent with the total simulated power curve of the rest electric equipment or the curve similarity is smaller than a system preset threshold, the electric equipment which is verified by current power-off is not abnormal, and the verification of other electric equipment is continued. After the abnormal equipment is determined, comparing a second difference power curve obtained by subtracting the total actual power curve of the abnormal equipment from the total simulated power curve of the residual electric equipment with the first difference power curve to determine whether the current monitoring area (indoor) has abnormal electricity consumption conditions except the current abnormal equipment, and if not, determining the actual power curve of the current abnormal equipment through the second difference power curve and the simulated power curve of the current abnormal equipment; if the current abnormal equipment exists, determining an actual power curve of the current abnormal equipment according to the difference value of the first difference power curve and the second difference power curve and combining the simulated power curve of the current abnormal equipment.

if not, the other electric equipment is abnormal equipment,
and after all other electric equipment is verified and equipment parameters are adjusted, if the total actual power curve is inconsistent with the total simulated power curve, the undetermined abnormal equipment is abnormal equipment.
It should be noted that, when abnormal verification is performed on the first level device which cannot be powered off in the working process, auxiliary verification is required to be performed through other electric equipment. Because the second curve similar data represents the probability value generated by the current electric equipment by the first difference power curve, when the second curve similar data is smaller than certain data, the first difference power curve can be determined to be irrelevant to the current electric equipment. And sequentially carrying out power-off abnormality verification on each other electric equipment according to the size of the second curve similar data by selecting one or more other electric equipment with the second curve similar data larger than a second preset threshold, and if the total actual power curve of each other electric equipment after power off is consistent with the total simulated power curve of the rest electric equipment or the curve similarity is larger than a system preset threshold, indicating that the first difference power curve is generated by abnormal electric power of the current abnormal equipment, and the current abnormal equipment is abnormal equipment.

if the power failure verification is inconsistent, the undetermined abnormal equipment is normal equipment, and the next electric equipment is selected as the undetermined abnormal equipment according to the similar data size of the second curve to carry out power failure verification until the abnormal equipment is determined.
It should be noted that, after the abnormal device is powered off, the total actual power of the current power consumption area should be the same as or similar to the total analog power of the remaining power consumption equipment, that is, the total actual power curve is consistent with the total analog power curve of the remaining power consumption equipment or the curve similarity is greater than the system preset threshold, and according to the second curve similarity data size, the power consumption equipment in the current power consumption area is sequentially determined as the to-be-determined abnormal device to perform power off abnormality detection, and the abnormal device in the current power consumption area is determined through the total actual power curve after each power off and the total analog power curve of the remaining power consumption equipment.
