The following describes in detail an artificial intelligence electrical line abnormal risk degree monitoring method and system provided by the present invention with reference to the accompanying drawings and specific embodiments.
Example 1
Referring to fig. 1, the application provides an artificial intelligence electrical line abnormal risk degree monitoring method, which includes the following steps:
s1: acquiring multi-dimensional data of each electric line in real time, wherein the multi-dimensional data comprises measuring point temperature rise and load current, and the measuring point temperature rise is acquired through measuring point temperature and environment temperature acquisition of a temperature field;
s2: obtaining a load temperature rise model according to the multidimensional data of the same line specification, and periodically obtaining a load temperature rise characteristic curve according to the load temperature rise model, wherein the load temperature rise characteristic curve is a standard temperature rise value corresponding to different load currents of the electric lines of the same line specification in a normal operation state;
s3: and obtaining the real-time abnormal risk degree of each electric line according to the load temperature rise characteristic curve.
The present embodiment will now be described in detail:
according to the artificial intelligence electrical line abnormal risk monitoring method, modern technology such as internet of things data collection, big data storage and big data analysis is utilized to collect multidimensional data of each electrical line, AI factors of the same line specification, namely load temperature rise characteristic curves, are calculated regularly based on the big data of the multidimensional data of each electrical line, then real-time data load temperature rise is compared with the AI factors, the risk degree of the real-time data of each electrical line can be visually seen, a basis is provided for electrical line abnormal risk judgment, and the method can be particularly applied to judgment of fire risk early warning, aging monitoring and the like of the electrical lines.
The main reasons for fire in the electric line are as follows: 1. short-circuiting; 2. overload; 3. the contact resistance is too large; according to joule's law: q = I2Rt, three causes, heat increase per unit time, causing temperature rise, potentially reaching the ignition point of insulators or other combustibles, causing fire. The higher the temperature the greater the risk.
According to the metal property of the wire core of the electric circuit, the resistivity changes along with the temperature change. From the resistance law R = (ρ × L)/S, taking the ambient temperature of 20 ℃ as an example, the magnitude of the resistance value of the core of the single-length electrical line is as follows:
R=R20*[1+a(T-20)]=ρ/S*[1+a(T-20)]
in the formula:
R20the resistance value omega of the core conductor at 20 ℃;
a is the temperature coefficient of conductor material of the wire core and DEG C-1;
T is the temperature of the wire core during working at DEG C;
rho is the resistivity of the conductor of the wire core, omega m;
s is the cross-sectional area of the conductor of the wire core, m2。
The heat generated per unit length of the electrical line per unit time is:
Q=I2ρ/S*[1+a(T-20)]formula one
The temperature field algorithm can be obtained from the formula one relative temperature T-20: Δ T = T-T environment
Q=I2ρ/S*[1+aΔT]Formula II
The heat generated by the electric circuit with the same specification and the same current and unit length in unit time is linearly related to the relative temperature delta T. The case of the electrical line temperature at this current can therefore be replaced by Δ T.
Therefore, in step S1 of this embodiment, the multidimensional data of each electrical line is acquired and obtained in real time based on the internet of things, and the acquired multidimensional data is stored, a concept of a temperature field is introduced in this embodiment, a temperature field is formed based on the measurement point temperature, the ambient temperature, and the meter box temperature, the temperature of the electrical line, the ambient temperature outside the meter box, and the temperature inside the meter box are respectively monitored, and a plane is formed by the three temperatures, so that the risk can be more comprehensively determined.
Referring to fig. 3, according to the characteristics of the electrical circuit, the risk level is higher at the upper point where the temperature rise is distributed at the same current, for example, at current 25A, than at the point where the temperature rise is between 15 and 18 ℃, than at the lower point where the temperature rise is distributed, for example, at 3 to 6 ℃, and different currents generate the same temperature rise, and the same temperature rise current becomes smaller and the risk level becomes higher. Based on the characteristics of the electrical circuit, a fuzzy comparison can be obtained at present, and the specific degree cannot be measured, for this reason, the present embodiment establishes a load temperature rise value standard of the electrical circuit which normally operates with the same specification of the electrical wire, as a standard temperature rise value of the load temperature rise of the electrical circuit with the same specification, that is, a load temperature rise characteristic curve.
Specifically, referring to fig. 2, step S2 of this embodiment specifically includes the following steps:
s21: classifying the multidimensional data of each electric circuit through a classification algorithm according to the circuit specification of each electric circuit, wherein the circuit specification comprises the material of the circuit, the wire diameter of the circuit and the like to obtain electric circuit data corresponding to different circuit specifications;
s22: clustering temperature rise values corresponding to the same load current in the electric line data into a class through a clustering algorithm, specifically clustering temperature rise values in the same load current range into a class to obtain a load temperature rise model, wherein the load temperature rise model is the temperature rise value distribution corresponding to different load currents under the same line specification;
s23: and calculating standard temperature rise values corresponding to different load currents of the electric lines with the same line specification through data statistics to obtain a load temperature rise characteristic curve. Specifically, step S23 in this embodiment specifically includes: s231: according to the load temperature rise model, the distribution probability corresponding to different temperature rise values under each load current is calculated in a statistical manner, specifically, the whole range of the temperature rise values is divided into a plurality of sections, and the probability that data points in each section occupy all data points under the load current is calculated; s232: taking the temperature rise value or the middle value of the temperature rise range corresponding to the highest distribution probability as the standard temperature rise value under the corresponding load current; s233: and obtaining a load temperature rise characteristic curve according to the standard temperature rise value under each load current.
Referring to fig. 3, a curve represents a load temperature rise characteristic curve, i.e., AI factor, of the same specification electrical line, and the line represents a range included in a temperature rise general distribution area under the same current, which can represent temperature rise characteristics of the electrical line under different currents. By means of the AI factor, the meaning of the abnormal risks represented by the same temperature rise values at different currents can be determined. For example, 10A and 20A in FIG. 3 also both have 25 ℃ temperature rises, but represent different degrees of risk, since the standard normal temperature rise for 10A is 2 ℃ and the standard normal temperature rise for 20A is 4 ℃ with corresponding differences of 23 ℃ and 21 ℃, respectively. It is clear that the degree of abnormal risk at 23 ℃ is greater, and the degree of abnormal risk at each point can be obtained by the method.
The embodiment combines the classification algorithm and the clustering algorithm to process the multidimensional data of each electric line, can facilitate the further analysis of the data, and meanwhile obtains the load temperature rise characteristic curve based on data statistics so as to accord with the general rule of the electric line under the current application scene, thereby improving the application range of the monitoring of the risk abnormal degree of the electric line and enabling the monitoring to be more objective.
Specifically, referring to fig. 3, in step S3 of this embodiment, the present embodiment compares and determines a temperature rise value of an electrical line running in real time with a standard temperature rise value corresponding to the same load current of a load temperature rise characteristic curve of the same electrical wire specification, and uses a difference between the temperature rise value and the standard temperature rise value as a basis for determining a risk level, where the greater the risk is, and uses a temperature rise difference between the temperature rise of the object to be measured and the temperature rise of a reference temperature rise as a real-time abnormal risk level of each electrical line, to visually determine whether there is an abnormal risk level in the monitored electrical line.
In the embodiment, the temperature rise of the measuring points and the load current of each electric circuit are collected in real time, the load temperature rise model with the same circuit specification is obtained according to the corresponding relation between the temperature rise of the measuring points and the load current, the current real-time collected load temperature rise characteristic curve is obtained based on the load temperature rise model, and the abnormal risk degree of each electric circuit is monitored through the load temperature rise characteristic curve, wherein the load temperature rise characteristic curve can be generated intelligently along with different application scenes, and can be updated intelligently at regular intervals according to real-time collected multidimensional data.

Through the processing, the abnormal risk condition of other multi-dimensional data of the electric circuit can be intuitively monitored.

Therefore, the abnormal risk degree of each data point is obtained, and a basis is provided for the abnormal comparison of different electric lines with the same specification.
Preferably, referring to fig. 1, step S3 is followed by step S5: and performing longitudinal and transverse analysis on a time dimension according to the real-time abnormal risk degree of each electric line, wherein the longitudinal analysis obtains the risk trend of each electric line and the probability of the same risk in the history, and the transverse analysis obtains the probability of the same risk in all the electric lines and the highest risk degree condition in all the electric lines.
