Description

Technical field

[0001] The utility model relates to the technical field of electric power monitoring, in particular to a power failure sensing device. [Background Technology]

[0002] Sudden power outages are a common problem, potentially caused by a variety of factors, including line damage due to severe weather, aging equipment, construction workers accidentally touching wires and causing them to break, excessive power consumption leading to line failures, or planned power outages in certain areas. Power outages not only cause inconvenience to residents and affect the normal operation of household appliances, but can also disrupt business activities and cause economic losses.

[0003] Locating the outage point after a power outage is crucial. First, quickly and accurately locating the outage point can help power companies quickly dispatch maintenance personnel to the site, shortening the outage and minimizing the impact on users. However, existing power outage sensing devices primarily consist of an early warning device, which is attached to power lines via two induction wires electrically connected to the early warning device. When a power outage occurs, the early warning device transmits a message indicating the outage. However, existing power outage sensing devices are large and complex in structure. Due to the limited space within the distribution box, installing the power outage sensing device is inconvenient. [Utility Model Content]

[0017] Compared with the prior art, the power outage sensing device provided by the present invention has the following beneficial effects:

[0018] 1. The utility model provides a power outage sensing device for detecting the working status of electric wires. The power outage sensing device includes a shell, a sensing component, a power supply and a clamping member. The clamping member includes a first clamping member and a second clamping member arranged on the same side of the shell. A clamping area is formed between the first clamping member and the second clamping member. The sensing component includes a first sensing wire, a circuit board and a second sensing wire. The circuit board and the power supply are accommodated in the shell.

One end of the second sensing wire is connected to the circuit board, and the other end passes through the second clamping member and is exposed in the clamping area. The power outage sensing device provided in this embodiment is usually placed in a distribution box, and the space inside the distribution box itself is small. Traditional power outage sensing devices are large in size and have a complex structure. They cannot be placed inside a distribution box and can only be connected to the wires in the distribution box through two sensing wires.

[0019] The power outage sensing device provided in this embodiment is smaller in size and can be directly clamped on the wires, making it very easy to install.

[0020] 2. The present invention includes at least one first clamping member and at least one second clamping member. A first clamping surface is defined on the side of the first clamping member closest to the second clamping member, and a second clamping surface is defined on the side of the second clamping member closest to the first clamping member. A distance is provided between the first and second clamping surfaces. The space between the first and second clamping surfaces is the clamping space, which primarily serves to accommodate the wires, allowing the first and second sensing wires exposed in the clamping space to come into contact with the wires.

[0021] 3. The first clamping member of the present invention includes a first clamping outer side surface and a first clamping inner side surface that are oppositely disposed and connected to the first clamping surface. A first limiting groove is defined on a side of the first clamping member that is adjacent to the second clamping member. The first limiting groove extends along a first direction through the first clamping outer side surface and the first clamping inner side surface.

[0022] The second clamping member includes a second outer clamping surface and a second inner clamping surface that are oppositely disposed and connected to the second clamping surface. A second limiting groove is defined on a side of the second clamping member that is adjacent to the first clamping member and corresponds to the first limiting groove. The second limiting groove extends through the second outer clamping surface and the second inner clamping surface along a second direction. The first limiting groove and the second limiting groove are used to limit the wire to prevent the wire from slipping out of the clamping space.

[0023] 4. The cross-sections of the first limiting groove and the second limiting groove of the present invention are semicircular, V-shaped, polygonal or semi-elliptical. The cross-sections are varied and there are many options. The purpose is to limit the sliding of the wires.

One end of the clamping member is set on the mounting surface, and the other end is bent toward the side close to the mounting surface to form an arc structure. The first clamping inner side surface and the second clamping inner side surface form a third angle with the bottom surface. The range of the third angle is 90° to 160°.

[0027] 8. The first limiting groove of the present invention defines a first channel connected to the interior of the housing. The first sensing wire passes through the first channel and is exposed within the first limiting groove. The second limiting groove defines a second channel connected to the interior of the housing. The second sensing wire passes through the second channel and is exposed within the second limiting groove. During the manufacturing process of the power outage sensing device, the first and second channels are first defined within the housing. The first sensing wire is then passed through the first channel, and the second sensing wire is then passed through the second channel to complete the assembly of the first and second sensing wires. This is simple and convenient.

[0028] 9. The housing of the present invention is provided with an accommodating space, and the circuit board is arranged in the accommodating groove close to the first channel and the second channel. A power supply groove is opened in the accommodating space along the length direction of the circuit board.

[0049] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] It should be noted that the terms "first" and "second" in the description and claims of the present utility model are used to distinguish different objects rather than to describe a specific order.

[0055] Locating the outage point after a power outage is crucial. First, quickly and accurately locating the outage point can help power companies quickly dispatch maintenance personnel to the site, shortening the outage and minimizing the impact on users. However, existing power outage sensing devices primarily consist of an early warning device, which is attached to power lines via two induction wires electrically connected to the early warning device. When a power outage occurs, the early warning device sends a power outage signal. However, existing power outage sensing devices are large and complex in structure. Due to the limited space inside the distribution box, installing the power outage sensing device is inconvenient.

[0056] Please combine Figures 1 to 3 The first embodiment of the utility model provides a power outage sensing device 10 for detecting the working status of electric wires. The power outage sensing device 10 includes a shell 1, a sensing component 2, a power supply 3 and a clamping member 4. The clamping member 4 includes two first clamping members 41 and a second clamping member 42 arranged on the same side of the shell 1. A clamping area is formed between the first clamping member 41 and the second clamping member 42. The sensing component 2 includes a first sensing line 21, a circuit board 22 and a second sensing line 23. The circuit board 22 and the power supply 3 are accommodated in the shell 1. One end of the first sensing line 21 is connected to the circuit board 22, and the other end passes through the first clamping member 41 and is exposed in the clamping area. One end of the second sensing line 23 is connected to the circuit board 22, and the other end passes through the second clamping member 42 and is exposed in the clamping area.

[0057] It can be understood that the first clamping member 41 and the second clamping member 42 of the power outage sensing device 10 provided in this embodiment are used to provide a clamping force on the wire, thereby fixing the power outage sensing device 10 on the exposed wire. The clamping area is used to accommodate the clamped wire. Specifically, the first induction line 21 and the second induction line 23 are both exposed in the clamping area, and when the first clamping member 41 and the second clamping member 42 clamp the wire, the portions of the first induction line 21 and the second induction line 23 exposed in the clamping area can come into contact with the exposed wire. That is, the wire and the first induction line 21 and the second induction line 23 are electrically connected, and the current on the wire will be transmitted to the circuit board 22 through the first induction line 21 and the second induction line 23, respectively. The circuit board 22 can then obtain the electrical signal on the wire.

[0058] It should be understood that the power outage sensing device 10 provided in this embodiment is typically placed in a distribution box, which itself has a small interior space. Conventional power outage sensing devices 10 are bulky and complex, making them difficult to place inside a distribution box. They must be connected to the wiring within the distribution box via two sensing wires, which then pass through the box and require a separate housing to house the power outage sensing device 10. This results in a bulky and inconvenient installation. The power outage sensing device 10 provided in this embodiment, however, is smaller and can be clamped directly onto electrical wiring, making installation very simple.

[0059] Specifically, the first and second clamping members 41, 42 are made of an elastic insulating material. It should be understood that the use of this insulating material prevents current from the wire from being directed toward the housing 1 through the first and second clamping members 41, 42, thereby improving safety when the user installs the power outage sensing device 10. Since the first and second clamping members 41, 42 are elastic, the user only needs to apply a thrust. When the first and second clamping members 41, 42 contact the wire, the first and second clamping members 41, 42 near the wire end move away from each other, increasing the distance between the first and second clamping members 41, 42 near the wire end, allowing the wire to smoothly enter the clamping area. Once the wire enters the clamping area, the user can remove the thrust. The deformation of the first and second clamping members 41, 42 generates an elastic force that clamps the wire, thereby securing the power outage sensing device 10 to the wire.

[0060] Preferably, the first clamping member 41 and the second clamping member 42 are integrally formed with the housing 1. It should be understood that the integral molding improves the integrity between the clamping member 4 and the housing 1. During the manufacturing process, there is no need to add the process step of assembling the first clamping member 41 and the second clamping member 42 to the housing 1, making the manufacturing process of the power outage sensing device 10 more convenient.

[0061] Further, please combine Figure 4 and Figure 5 The number of the first clamping member 41 and the second clamping member 42 is at least one, a first clamping surface 411 is set on the side of the first clamping member 41 close to the second clamping member 42, and a second clamping surface 421 is set on the side of the second clamping member 42 close to the first clamping member 41, and a distance is left between the first clamping surface 411 and the second clamping surface 421. It should be understood that the distance left between the first clamping surface 411 and the second clamping surface 421 is determined according to the diameter of the wire to be clamped. Specifically, the distance is less than or equal to the diameter of the wire. Among them, the space between the first clamping surface 411 and the second clamping surface 421 is the clamping space, and the main function of the clamping space is to accommodate the wire. The first induction line 21 and the second induction line 23 exposed in the clamping space can come into contact with the wire.

[0062] Further, see Figures 4 to 7 The first clamping member 41 includes a first clamping outer side surface 412 and a first clamping inner side surface 413 that are oppositely disposed and connected to the first clamping surface 411. A first limiting groove 414 is defined on a side of the first clamping member 41 close to the second clamping member 42. The first limiting groove 414 extends through the first clamping outer side surface 412 and the first clamping inner side surface 413 along a first direction a. The second clamping member 42 includes a second clamping outer side surface 422 and a second clamping inner side surface 423 that are oppositely disposed and connected to the second clamping surface 421. A second limiting groove 424 is defined on a side of the second clamping member 42 close to the first clamping member 41, corresponding to the first limiting groove 414. The second limiting groove 424 extends through the second clamping outer side surface 422 and the second clamping inner side surface 423 along a second direction b (not shown). The second direction b is the same as and parallel to the first direction a.

[0063] As will be appreciated, in a normal state, the first clamping member 41 and the second clamping member 42 are arranged parallel to each other on one side of the housing 1. When a user clamps the power outage sensing device 10 to an electrical wire, they typically grip opposite sides of the housing 1, with the first clamping member 41 and the second clamping member 42 facing the electrical wire. As the user continues to push the housing 1, the ends of the first clamping member 41 and the second clamping member 42 away from the housing 1 first contact the electrical wire. At this point, the first inner clamping surface 413 and the second inner clamping surface 423 move closer to the electrical wire, while the first outer clamping surface 412 and the second outer clamping surface 422 move further away from the electrical wire. Furthermore, the end of the first clamping member 41 away from the housing 1 deforms in a direction away from the second clamping member 42, while the end of the second clamping member 42 away from the housing 1 deforms in a direction away from the first clamping member 41, allowing the electrical wire to enter the clamping space. When the wire enters the first limiting groove 414 and the second limiting groove 424, the user stops pushing the housing 1. At this time, the ends of the first clamping member 41 and the second clamping member 42 away from the housing 1 will return to their normal state, and the wire will be confined within the first limiting groove 414 and the second limiting groove 424. It should be understood that the first limiting groove 414 and the second limiting groove 424 are used to limit the wire to prevent it from slipping out of the clamping space.

[0064] Optionally, the cross-sections of the first limiting groove 414 and the second limiting groove 424 are semicircular, V-shaped, polygonal, or semi-elliptical. It should be understood that the cross-sections of the first limiting groove 414 and the second limiting groove 424 are various and can be selected in many ways, all for the purpose of limiting the sliding of the wire.

[0065] Furthermore, the first direction a forms a first angle n1 with the first clamping inner side surface 413, and the second direction b forms a second angle n2 (not shown) with the second clamping inner side surface 423, wherein the first angle n1 and the second angle n2 are the same and both range from 60° to 150°. Specifically, the first angle n1 and the second angle n2 can be 60°, 90°, 120° or 150°. It can be understood that when the power outage sensing device 10 is fixed to the wire, it is necessary to ensure that the end of the first clamping member 41 and the second clamping member 42 close to the housing 1 is as far away from the wire as possible, thereby avoiding contact between the wire and the housing 1. If the design of the second angle n2 is unreasonable, the wire may come into contact with the housing 1 when clamped.

[0066] Specifically, after the wire enters the first limiting groove 414 and the second limiting groove 424, the axial direction of the wire is the same as the first direction a and the second direction b. This embodiment specifically designs the range of the second angle to ensure that, when the first clamping member 41 and the second clamping member 42 clamp the wire, they form a second angle n2 with the wire, thereby keeping the wire as far away as possible from the end where the first clamping member 41 and the second clamping member 42 are connected to the housing 1. In other words, the wire is kept as far away from the housing 1 as possible.

[0067] For further information, please refer to Figures 5 to 7 When the user fixes the power outage sensing device 10 on the wire, they need to ensure that their hands are as far away from the wire as possible to prevent the current on the wire from coming into contact with their hands. The housing 1 of this embodiment includes a mounting surface 11 and a bottom surface 12 connected to the mounting surface 11. One end of the clamping member 4 is set on the mounting surface 11, and the other end is bent toward the side close to the mounting surface 11 to form an arc structure. The first clamping inner side surface 413 and the second clamping inner side surface 423 form a third angle n3 with the bottom surface 12. The range of the third angle n3 is 90° to 160°. Specifically, the third angle n3 can be 90°, 120°, 150°, or 160°.

[0068] Understandably, users typically grip the two opposing side surfaces 13, which are connected to the mounting surface 11 and the bottom surface 12, respectively. If the third angle n3 is not properly designed, the user's hand may come close to the wire when the wire is clamped. This embodiment specifically designs the range of the third angle so that when the housing 1 is clamped on the wire, the housing 1 is as parallel to the axial direction of the wire as possible. This maximizes user safety, whether installing or removing the power outage sensing device 10.

[0069] In addition, if the clamping member 4 is parallel or perpendicular to the length of the housing 1, when the user needs to install the power outage sensor 10 on the wire, they need to pinch the housing 1 with their hands and push the housing 1 toward the wire. If the user uses too much force, their fingers may come into contact with the wire, which greatly increases the safety hazard. In this embodiment, the end of the clamping member 4 away from the mounting surface 11 has an arc-shaped structure. The arc-shaped structure is beautifully designed, and when the user applies thrust to the housing 1, they only need to apply thrust in a direction parallel to the axial direction of the wire to clamp the wire on the wire, which improves the safety of the installation process.

[0070] Furthermore, please combine Figure 1 、 Figure 5 and Figure 7The power failure sensing device 10 also includes a latch 5, a first locking hole 415 is opened at one end of the first clamping member 41 away from the shell 1 in a direction perpendicular to the first clamping surface 411, and a first limiting groove 414 is arranged between the first locking hole 415 and the shell 1, and a second locking hole 425 is opened at one end of the second clamping member 42 away from the shell 1 in a direction perpendicular to the second clamping surface 421, and the second limiting groove 424 is arranged between the second locking hole 425 and the shell 1; the latch 5 passes through the first locking hole 415 and the second locking hole 425 respectively and is detachably connected to the clamping member 4.

[0071] It can be understood that once the wire enters the first limiting groove 414 and the second limiting groove 424, the latch 5 can be passed through the first locking hole 415 and the second locking hole 425, so that the latch 5 is fixed to the clamping member 4. When the wire is shaken by external force, the latch 5 limits the wire and prevents it from slipping out of the clamping space.

[0072] Furthermore, please combine Figure 8 The first limiting groove 414 defines a first channel 15 communicating with the interior of the housing 1. The first sensing line 21 passes through the first channel 15 and is exposed within the first limiting groove 414. The second limiting groove 424 defines a second channel 16 communicating with the interior of the housing 1. The second sensing line 23 passes through the second channel 16 and is exposed within the second limiting groove 424. It can be understood that during the manufacturing process of the power outage sensing device 10, the first channel 15 and the second channel 16 are first defined within the housing 1. The first sensing line 21 then passes through the first channel 15 and the second sensing line 23 then passes through the second channel 16, thereby completing the assembly of the first sensing line 21 and the second sensing line 23. This is simple and convenient.

[0073] Furthermore, a housing space is defined within the housing 1, with the circuit board 22 positioned within the receiving slot near the first and second channels 15, 16. A power slot 14 is defined within the receiving slot along the length of the circuit board 22, with the power supply 3 housed within the slot. As will be appreciated, the placement of the circuit board 22 near the first and second channels 15, 16 minimizes the length of the first and second sensing lines 21, 23. This means that when the first and second sensing lines 21, 23 come into contact with the electrical wires, they can more quickly transmit electrical signals to the circuit board 22. Furthermore, the length of the power slot 14 aligns with that of the circuit board 22, significantly reducing the width of the housing 1 and improving space utilization within the housing 1.

[0074] Furthermore, the circuit board 22 is provided with an electrically connected voltage sensing module 221 and an Internet of Things module 222. Specifically, the voltage sensing module 221 is used to connect to the first sensing line 21 and the second sensing line 23 to obtain the electrical signal transmitted from the wire to the circuit board 22. The Internet of Things module 222 is used to receive the electrical signal from the voltage sensing module 221, convert the electrical signal into power information, and then transmit it to the outside world. In other words, the main function of the power outage sensing device 10 provided in this embodiment is to collect the electrical signal of the wire when there is no power outage or the electrical signal during a power outage. Through the functions of the voltage sensing module 221 and the Internet of Things module 222, the electrical signal is converted into power information and transmitted, making it convenient for the user to monitor the wire.

[0075] Specifically, please combine Figure 1 、 Figure 8 and Figure 9 The voltage sensing module 221 includes a detection circuit, which includes a current input terminal I1, a power supply 3VCC terminal, a transistor U1, a transistor U2, a transistor U3, a filter capacitor C1, a resistor R1, an adjustable resistor R2, a resistor R3 and a current output terminal O1;

[0076] The base of the transistor U1 is connected to the current input terminal I1, the collector of the transistor U1 is connected to the power supply 3VCC terminal, the emitter of the transistor U1 is connected to the base of the transistor U2, the collector of the transistor U2 is connected to the power supply 3VCC terminal, the emitter of the transistor U2 is grounded, the collector of the transistor U3 is connected in series with the resistor R1 and then connected to the power supply 3VCC terminal, the emitter of the transistor U3 is grounded, the collector of the transistor U3 is also connected in series with one end of the filter capacitor C1, and the other end of the filter capacitor C1 is grounded, wherein the function of the filter capacitor C1 is to filter the current; the adjustable resistor R2 includes two fixed pins and one sliding pin, the collector of the transistor U3 is also connected to one fixed pin of the adjustable resistor R2, the other fixed pin of the adjustable resistor R2 is connected in series with the resistor R3 and then grounded, and the sliding pin of the adjustable resistor R2 is connected to the current output terminal O1, wherein the resistor R and the resistor R3 are both protective resistors.

[0077] It can be understood that the wire transmits the current (the electrical signal is exemplified by current) to the current input terminal I1 through the first sensing line 21 and the second sensing line 23. The current will be amplified in three stages after passing through the transistors U1, U2, and U3. The amplified current will enter the adjustable resistor R2, which has a preset resistance value. The current will pass through the sliding foot of the adjustable resistor R2 and enter the current output terminal O1. The current output from the current output terminal O1 will be compared with the preset current value. If it is lower than the preset current value, the surface wire is in a power-off state. At this time, the voltage sensing module 221 will generate a power-off signal to the Internet of Things module 222. The Internet of Things module 222 will convert the power-off signal into power information and send it to the outside world, so that the user can know that the wire at that location has failed.

[0078] Please combine Figure 1 and Figure 10 The second embodiment of the present invention further provides a power information monitoring method, which is used in a power monitoring system. The power monitoring system includes a database terminal and the above-mentioned power outage sensing device. The detection method includes:

[0079] S1, providing a power outage sensing device, and fixing the power outage sensing device on the electric wire at a predetermined position;

[0080] S2, the power failure sensing device enters the sleep mode after receiving the electrical signal transmitted by the power line for the first time. The sleep mode includes the timed wake-up mode and the power failure wake-up mode;

[0081] S3, when the power outage sensing device continuously receives the electrical signal, the power outage sensing device is in a timed wake-up mode, and the power outage sensing device converts the electrical signal into a power supply signal within a set time interval, and then converts the power supply signal to generate power information for sending to the database terminal;

[0082] S4, when the power outage sensing device does not receive an electrical signal, the power outage sensing device is in a power outage wake-up mode, and a weak current signal is generated in the power outage sensing device. The weak current signal is amplified and processed to generate a power outage signal, and then the power outage signal is converted to generate power information for sending to the database terminal.

[0083] It can be understood that the power information monitoring method provided in this embodiment can detect the power information of the electric wires. Specifically, the above-mentioned power outage sensing device can be fixedly clamped on the electric wires in distribution boxes at different locations. When the power outage sensing device is first clamped on the electric wire, the power outage sensing device will receive the electrical signal transmitted by the electric wire, and the power outage sensing device will automatically enter the sleep mode at this time. Since the power outage sensing device relies on the internal power supply for power supply, if the power outage sensing device monitors the electric wires at all times, the power supply inside the power outage sensing device will soon be exhausted. Therefore, when the power outage sensing device is first clamped on the electric wire, it will automatically enter the sleep mode. The sleep mode means that the power outage sensing device is powered in a standby state, which can greatly increase the standby time of the internal power supply of the power outage sensing device and reduce the burden caused by the power supply and frequent replacement of the power supply.

[0084] Furthermore, the sleep mode includes a timed wake-up mode and a power-off wake-up mode. Specifically, two situations usually occur after the power outage sensing device enters the sleep mode.

[0085] It should be understood that the first scenario is that the power lines at that location have not experienced a power outage. In this case, the power outage sensing device can continue to receive electrical signals transmitted by the power lines. In this case, the power outage sensing device is in a timed wake-up mode. Within a set time interval, the power outage sensing device converts the electrical signal into a power supply signal, which is then converted to generate power information for transmission to a database terminal. For example, the power outage sensing device takes one minute every 24 hours to convert the received electrical signal into a power supply signal. The power supply signal primarily indicates that the power lines at that location are still receiving power. Furthermore, the power supply signal can be converted into power information, which the power outage sensing device then transmits to an external database terminal via its built-in Internet of Things module. For example, the user can receive the power information by having the Internet of Things module transmit the power information to the cloud, which then transmits the power information to the user's mobile phone terminal. The database terminal described in this embodiment can be the cloud or an external communication terminal such as a base station. The details will not be elaborated on here.

[0086] It should be understood that the second situation is that the power outage occurs in the power lines at that location, and the power outage sensing device does not receive the electrical signal transmitted by the power lines. At this time, a weak current signal is generated in the power outage sensing device, which is amplified and processed to generate a power outage signal, and then the power outage signal is converted to generate power information for sending to the database terminal. For example, at a certain time, a power outage occurs due to a fault in the power line. When the power outage sensing device does not receive the electrical signal transmitted by the power line at that time, the power supply inside the power outage sensing device will wake up to supply power and generate a weak current signal. The weak current signal is amplified and processed by the voltage sensing module to generate a power outage signal, and the Internet of Things module in the power outage sensing device then converts the power outage signal to generate power information. Finally, the power outage sensing device transmits the power information to the external database terminal through its built-in Internet of Things module.

[0087] It can be understood that the power information monitoring method provided in this embodiment can monitor the power lines regardless of whether the power lines are out of power or not, and is highly practical.

[0088] Specifically, power information includes any one or a combination of the location of the power outage sensing device, time information, current and voltage information of the power line to which the power outage sensing device is attached, and temperature and humidity information of the environment surrounding the power outage sensing device. It should be understood that the specific forms of power information can vary, making it easier for users to monitor power lines at specific locations.

[0089] Furthermore, in the above steps S3 and S4, after generating the power information for sending to the database terminal, the following steps are further included:

[0090] Send power information to the database terminal and accumulate it in the database terminal to form historical power information;

[0091] Provide a basic analysis model, input historical power information into the analysis model for analysis to obtain a power outage warning model;

[0092] Providing environmental forecast information, including weather information and / or power restriction information for a preset location at a first future time point or a first time period;

[0093] Inputting environmental prediction information into a power outage warning model and predicting whether a power outage will occur at a preset location at a first time point or a first time period in the future;

[0094] If so, a power outage warning signal is generated.

[0095] It can be understood that the power outage sensing device provided by this embodiment can collect power information and build a power monitoring system based on the power information. Specifically, the power information that can be collected by the power outage sensing device is first sent to the database terminal. As time accumulates, a sufficient amount of historical power information will be accumulated inside the database terminal. For example, historical power information can refer to the information about the power outage that occurred at a certain point in time for the power line at a certain location, which also includes the temperature and humidity information at that point in time. Furthermore, when a sufficient amount of historical power information is accumulated, a basic analysis model can be provided, and the historical power information can be input into the analysis model for analysis based on the algorithm to obtain a power outage warning model. For example, a decision tree model or a random forest model can be used: specifically, both models are prediction models based on a tree structure, in which the decision tree gradually approaches the target variable by dividing the data set into multiple subsets, while the random forest improves the prediction accuracy by constructing multiple decision trees and performing weighted averaging of their prediction results.

[0096] Furthermore, after obtaining the power outage warning model, environmental prediction information can be provided. Specifically, the environmental prediction information includes weather information and / or power restriction information at the preset location at the first time point or the first time period in the future. Exemplarily, after the weather information for the next 12 hours at the preset location is input into the power outage warning model, the power outage warning model will output a prediction result, which mainly refers to whether the preset location will have a power outage in the next 12 hours. If the prediction result shows that the preset location will have a power outage in the next 12 hours, a power outage warning signal will be generated accordingly. It should be understood that the input environmental prediction information can also be whether the preset location will be artificially power-restricted at the first time point or the first time period in the future. Due to power restrictions, the power of some equipment will fluctuate, which can easily cause power failures in the wires.

[0097] It should be understood that in this embodiment, the power outage warning model can be used to provide early warning for power lines at a certain location, so that power management personnel can make predictions in advance and facilitate personnel to arrive at the scene in advance to perform early warning maintenance.

[0098] Furthermore, after generating the power outage warning signal, the following steps are also included:

[0099] Receiving real-time power information at a preset location at a first future time point or a first time period;

[0100] Determine whether the power outage warning signal is accurate based on power information;

[0101] If not, the real-time power information is input into the power outage warning model to optimize the power outage warning model.

[0102] It should be understood that after the user uses the power outage warning model to issue an advance warning for the power lines at a certain location, the user can receive real-time power information and determine whether the prediction of the power outage warning model is accurate. If it is inaccurate, the real-time power information can also be input into the power outage warning model to optimize the power outage warning model. For example, after the weather information for the next 12 hours at a preset location is input into the power outage warning model, the power outage warning model will output a warning signal that a power outage will occur. However, in the next 12 hours, the user receives real-time power information that there is no power outage at the power lines at that location, which indicates that the power outage warning signal is inaccurate. At this time, the real-time power information that was incorrectly judged by the power outage warning model can be input into the power outage warning model to update and optimize the power outage warning model.

[0103] Please combine Figure 10 and Figure 11 In order to solve the above problems, this embodiment also provides a power monitoring system, which is used to execute the above-mentioned power information monitoring method.

[0104] Compared with the prior art, the power monitoring system provided by the present invention has the same beneficial effects as the power information monitoring method, which will not be described in detail here.

[0105] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
