Detailed Description
In order to further describe the technical means and effects adopted by the invention to achieve the preset aim, the following detailed description refers to the specific implementation, structure, characteristics and effects of a modularized electric intelligent control method and system according to the invention by combining the accompanying drawings and the preferred embodiment. In the following description, different "one embodiment" or "another embodiment" means that the embodiments are not necessarily the same. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
The invention provides a modularized electric intelligent control method and a specific scheme of a system, which are specifically described below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of steps of a modular electric intelligent control method according to an embodiment of the invention is shown, the method includes the following steps:
Step S001: and collecting historical voltage data sequences of a plurality of electrical modules.
It should be noted that, in the conventional method, whether the electric module is connected to the voltage regulator is directly determined according to whether the voltage data of different electric modules are in the normal voltage range, so that the rationality of the electric module connected to the voltage regulator is reduced. Therefore, the embodiment provides a modularized electric intelligent control method.
Specifically, in order to implement the modularized electric intelligent control method provided in this embodiment, this embodiment is not described with respect to a certain electric intelligent control system, which includes electric modules with a serial mode and a parallel mode as a link mode, and the specific process includes the steps of: taking an electrical intelligent control system with a preset module flow direction as a horizontal direction and comprising 50 electrical modules as an example, arranging all the electrical modules according to the preset module flow direction, and connecting household alternating current to the input end of a first electrical module; collecting voltage data of each electric module once every 2 seconds by using a voltage sensor, wherein the total collection time is 200 seconds; taking any one electric module as an example, arranging all voltage data of the electric module according to the sequence from small to large of acquisition time, and recording the arranged sequence as a historical voltage data sequence of the electric module; and acquiring historical voltage data sequences of all the electrical modules. Wherein each electrical module corresponds to a link mode, and there are two link modes: respectively a series mode and a parallel mode. In addition, it should be noted that, in this embodiment, the number of electrical modules, the collection interval, and the collection total time are not specifically limited, where the number of electrical modules, the collection interval, and the collection total time may be determined according to specific implementation conditions.
So far, the historical voltage data sequence of all the electric modules is obtained through the method.
Step S002: dividing the historical voltage data sequence into a plurality of historical voltage data segments; and obtaining the voltage fluctuation degree of each electrical module according to the variation difference of the voltage data among the historical voltage data segments.
It should be noted that, because the distribution structures of the electronic elements inside the different electrical modules are not completely the same, the voltage ranges in which the different electrical modules can work normally will also be different; for any one of the electrical modules, if the voltage data of the electrical module in a certain period of time is within a voltage range in which the electrical module can normally operate, it is indicated that the voltage data of the electrical module in the period of time is already in a dynamically stable state, and the difference between the maximum value and the minimum value of the voltage data in the period of time is smaller. In order to make the final determination of the electric module which needs to be connected with the stabilizer more accurate, the voltage fluctuation degree of the electric module is obtained through the maximum variation difference of the voltage data of the electric module in different time periods so as to facilitate subsequent analysis and processing.
Specifically, a voltage data amount T1 is preset, where the embodiment is described by taking t1=30 as an example, and the embodiment is not specifically limited, where T1 may be determined according to specific implementation conditions; taking any one electric module as an example, recording a data segment formed by every T1 voltage data in a historical voltage data sequence of the electric module as a historical voltage data segment, and obtaining all the historical voltage data segments. In addition, if the actual remaining voltage data in the historical voltage data sequence of the electrical module does not satisfy the preset T1, the data segment formed by the actual remaining voltage data in the historical voltage data sequence of the electrical module is taken as a historical voltage data segment.
Further, the initial voltage fluctuation degree of the electric module is obtained according to all historical voltage data segments of the electric module. The calculation method of the initial voltage fluctuation degree of the electric module comprises the following steps:
；
Wherein represents an initial voltage fluctuation degree of the electric module; the/> represents the number of all historical voltage data segments for the electrical module; the/> represents the number of all historical voltage data segments except the/> historical voltage data segment in all historical voltage data segments of the electrical module; the/> represents the maximum of all voltage data in the/> historical voltage data segment; the/> represents the maximum value of all voltage data in the/> historical voltage data pieces except the/> historical voltage data piece; the/> represents the minimum of all voltage data in the/> historical voltage data segment; Representing the minimum of all voltage data in the/> historical voltage data segments except the/> historical voltage data segments; and/> denotes taking absolute value. The greater the initial voltage fluctuation degree of the electric module, the greater the cost for stabilizing the voltage data of the electric module, reflecting the more the electric module needs to use a voltage stabilizer. Obtaining initial voltage fluctuation degrees of all the electric modules, carrying out linear normalization on all the initial voltage fluctuation degrees, and recording each normalized initial voltage fluctuation degree as a voltage fluctuation degree.
So far, the voltage fluctuation degree of all the electric modules is obtained through the method.
Step S003: according to the difference of voltage data of the same acquisition time among the electric modules, a plurality of front voltage difference values of each electric module and each front influence module are obtained; obtaining the influence degree of the front-end module of each electrical module according to the correlation of the voltage fluctuation degrees among the electrical modules and the front-end voltage difference values; combining the electrical modules according to the link mode to obtain a plurality of linked electrical module combinations; and obtaining the stable efficiency factor of each electric module according to the influence conditions among the influence degrees of the front modules of different electric modules in the linked electric module combination.
It should be noted that, in an actual electrical intelligent control system, there are two link modes, one is a serial mode and the other is a parallel mode; in the series mode, the electrical modules are connected in series, and the voltage of the output end in the series mode is ideally obtained by superposing the voltages of the series electrical modules; in the parallel mode, the electric modules are connected in parallel, and the voltages of the corresponding electric modules are the same in ideal case, and the voltages of the output ends in the parallel mode are the same as those of the parallel electric modules. However, in practical situations, different electrical modules have a certain influence on the current flowing through the electrical modules due to different sensitivity of the electronic components in the electrical modules to voltage, so that the voltage data of the different electrical modules in the link mode will interfere with each other, and the original voltage data characteristics of the different electrical modules will be destroyed to a certain extent. In order to make the final determination of the electric modules which need to be connected to the stabilizer more accurate, the embodiment obtains the influence degree of the front-end module of the electric modules by analyzing the interference condition among the electric modules so as to facilitate the subsequent analysis and processing.
It should be further noted that, after the voltage stabilizer is installed on different electrical modules, different degrees of influence can be generated on the subsequent electrical modules; for a plurality of electric modules in the parallel mode, if a voltage stabilizer is installed on a front electric module, the voltage data between the electric modules in the parallel mode are similar in actual conditions, so that good stable efficiency is kept for the electric modules in the parallel mode; while the situation is exactly the opposite for several electrical modules in parallel mode. Therefore, in order to make the final determination of the electrical module to be connected to the stabilizer more accurate, the present embodiment obtains a stable efficiency coefficient according to the influence degree of the front-end module.
Specifically, a pearson correlation coefficient of the voltage fluctuation degree of any two electrical modules is obtained; taking any one electric module as an example, each electric module in front of the electric module is recorded as a front-end influence module of the electric module; taking any front-end influence module of the electric module as an example, in the historical voltage data sequence of the electric module and the historical voltage data sequence of the front-end influence module, recording the absolute value of the difference value of two voltage data at the same acquisition time as a front-end voltage difference value of the electric module and the front-end influence module, and acquiring all front-end voltage difference values of the electric module and the front-end influence module; and acquiring all front voltage difference values of the electric module and all front influencing modules.
Further, the influence degree of the front-end module of the electric module is obtained according to all front-end voltage difference values of the electric module and the pearson correlation coefficient of the electric module and each corresponding front-end influence module. The procedure of obtaining the pearson correlation coefficient is a known technique, and this embodiment will not be described in detail. In addition, the method for calculating the influence degree of the front module of the electrical module comprises the following steps:
；
Wherein denotes a front module influence degree of the electric module; the/> represents all the front-end influencing modules of the electrical module; the/> represents the variance of all front voltage difference values of the first/> front influencing modules and the electrical module; Representing the variance of all front voltage difference values of the first/ front-end influencing modules and the electrical module; the/> represents the pearson correlation coefficient of the/> pre-arranged influencing module of the electrical module with the voltage fluctuation degree of the electrical module. If the influence degree of the front-end module of the electric module is larger, the electric module is more influenced by the front-end influence module, and the cost for reflecting the voltage state of the electric module to be independently stabilized is larger. And obtaining the influence degree of the front module of each electrical module. And obtaining the influence degree of the front modules of all the electric modules.
Further, taking any one of the electric modules as an example, among all the electric modules following the electric module, a combination of electric modules having a continuous serial mode of the link mode is referred to as a serial electric module combination, and a combination of electric modules having a continuous parallel mode of the link mode is referred to as a parallel electric module combination; each series electric module combination and each parallel electric module combination are marked as a linked electric module combination of the electric module, and all the linked electric module combinations of the electric module are obtained; recording any one electric module in any one linked electric module combination as a subsequent influence module, recording the number of all electric modules between the electric module and the subsequent influence module as a subsequent module difference, and recording the product of the subsequent module difference and the influence degree of a front module of the subsequent influence module as the stable benefit of the electric module and the subsequent influence module; and obtaining the stability benefit of all subsequent influencing modules in the combination of the electric module and the linked electric module, and obtaining the stability benefit of all subsequent influencing modules in the combination of the electric module and all linked electric modules. Wherein each electrical module corresponds to a plurality of linked electrical module combinations, each linked electrical module combination comprising a plurality of electrical modules.
Further, a stable efficiency coefficient of the electrical module is obtained according to all the linked electrical module combinations of the electrical module and the stability benefits of the electrical module and each subsequent influencing module. The calculation method of the stable efficiency coefficient of the electrical module comprises the following steps:
；
Wherein denotes a stable efficiency coefficient of the electrical module; the/> represents the number of all linked electrical module combinations for that electrical module; the/> represents the number of all series-connected electrical module combinations among all linked electrical module combinations of the electrical module; the/> represents the number of all subsequent influencing modules in the/> series electrical module combination; the/> represents the stable benefit of the/> subsequent influencing module and the electrical module in the/> series electrical module combination; the/> represents a preset hyper-parameter, in this embodiment preset/> , for preventing the denominator from being 0; the/> represents a cumulative sign; the/> denotes an exponential function with a base of natural constant; the embodiment adopts/> functions to present inverse proportion relation and normalization processing, and an implementer can select the inverse proportion functions and the normalization functions according to actual conditions; the/> represents a major influencing factor of the stability efficiency of the electrical module; and/> denotes the weight of the main influencing factor of the stabilizing efficiency of the electrical module. And if the stability efficiency coefficient of the electric module is larger, the stability efficiency of the voltage data of the electric module after the voltage stabilizer is installed is larger, and the benefit brought by the electric module after the voltage stabilizer is installed is reflected to be larger. And obtaining stable efficiency coefficients of all the electric modules, carrying out linear normalization on all the stable efficiency coefficients, and recording each normalized stable efficiency coefficient as a stable efficiency factor.
So far, the stable efficiency factors of all the electric modules are obtained through the method.
Step S004: according to the influence conditions of voltage fluctuation degrees of all the electric modules after the voltage stabilizer is installed on different electric modules, obtaining the stable income factor of each electric module; and performing voltage stabilizing treatment on the electric module according to the stable income factor and the stable efficiency factor.
It should be noted that the stability efficiency factor of a single electrical module characterizes the stability benefit of the single electrical module; in actual situations, the more voltage regulators are installed, the greater the corresponding cost will be; considering actual cost factors, the embodiment reduces the cost of final voltage stabilization as much as possible on the basis of ensuring the voltage stabilization efficiency to reach the minimum qualified efficiency; the electric module which finally needs to be provided with the voltage stabilizer is obtained by analyzing the stable efficiency factors of all electric modules in the system and the fluctuation condition of corresponding voltage data.
