Description

Technical Field

[0001] This invention relates to the field of financial system technology, specifically to a method and apparatus for electricity bill calculation based on big data. Background Technology

[0002] Electricity billing, as a core component of electricity management, falls under the categories of product lifecycle management, product data management, and product process management. Following smart contracts and business rules, the quality of electricity billing directly impacts the normal operation of the power supply department's electricity marketing business and has a crucial influence and significance for the sustainable development of power companies. Traditional electricity billing relies primarily on manual calculation. After a user's electricity bill is generated, manual checks are performed to verify for errors, anomalies, and changes in user information. This method is inefficient. While automated computer-based electricity billing has gradually developed with technological advancements, it essentially transfers manual tasks such as anomaly checks, user information change checks, bill calculation accuracy, and payment success to computers. It doesn't consider the user's perspective in the billing process and fails to collect user electricity consumption data to provide better data support for subsequent electricity marketing operations.

[0003] In existing technologies, when users check their electricity bills offline, they can do so and pay at self-service kiosks. However, during this process, it is difficult for users to know the actual calculation method and the accuracy of the accounting process, and it is impossible to better demonstrate the accounting process to dispel users' doubts. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a big data-based electricity billing method and apparatus to solve the problems mentioned in the background. The invention features a novel structure. During use, the display component is delivered from within the system box. After recognizing the user's identity information, the system box adjusts the corresponding secondary screen to the bottom of the main screen according to the user's past electricity consumption levels. The secondary screen displays a model derived from the customer's past monthly electricity consumption records, predicting the electricity consumption for the current month. The main screen displays the current actual consumption value, allowing for a direct comparison. This improves the accuracy of the calculation when the error is small, and allows for timely manual calculation by staff when the error is large, preventing further errors.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electricity billing device based on big data, comprising a system box, with cover plates rotatably mounted on both sides of the top of the system box via hinges; a storage cavity is provided on the top of the system box, and a display component is stored inside the storage cavity; the display component includes a vertical frame, with a rotating frame fixed inside the vertical frame; three secondary screens are equidistantly fixed on the rotating shaft surface of the rotating frame; a main screen is mounted on the top of the vertical frame, and the main screen and the lower secondary screens are on the same plane; a mounting shaft is fixed at the bottom of the main screen, and both ends of the mounting shaft rotatably extend out of the vertical frame; two first spring telescopic rods are fixed at the bottom of the storage cavity, and the extended ends of the first spring telescopic rods are fixedly connected to the bottom of the vertical frame; an operation panel is rotatably mounted on the front of the system box via a rotating shaft, and a vertical frame is slidably mounted on top of the operation panel of the system box; the vertical frame wraps around the outside of the vertically positioned operation panel; and the operation panel is kinetically connected to the cover plate.

[0008] Furthermore, the display component also includes baffles. Two baffles are symmetrically mounted on the rear end of the rotating frame via a rotating shaft, and the baffles cover the surfaces of the two secondary screens at the rear end respectively. One end of the mounting shaft extends through the surface of the vertical frame and is mounted with a first transmission belt. The other end of the first transmission belt is rotatably and fixedly connected to the baffle at the upper end of the rotating frame.

[0009] Furthermore, a transmission gear is installed at the other end of the rotating frame corresponding to the rotatable connection of the two baffles. The two transmission gears are meshed and connected, and the transmission gears are fixedly connected to the rotating end of the baffle at the corresponding position.

[0010] Furthermore, a first motor is fixed on the outer surface of the top side baffle of the system box, and a first connecting shaft is fixed at the output end of the first motor. The other end of the mounting shaft passes through the vertical frame and is fixed to a first socket. The first connecting shaft is slidably inserted into the first socket.

[0011] Furthermore, a second motor is fixed on the outer surface of the cover plate at the other end of the system box, and a second connecting shaft is fixed on the output end of the second motor. The rotating shaft of the rotating frame is fixed with a second socket, and the second connecting shaft is slidably inserted into the second socket. Slots are provided on the surfaces of the first socket and the second socket, and protrusions are provided on the surfaces of the first connecting shaft and the second connecting shaft.

[0012] Furthermore, a second spring telescopic rod is fixed on the outer walls of both sides of the system box, and the top of the second spring telescopic rod is fixedly connected to the top two sides of the vertical frame.

A second transmission belt is fixed to the rear end of the first bevel gear, and the pulley at the other end of the second transmission belt is fixedly sleeved on the rotation position of the cover plate.

[0014] A method for calculating electricity costs based on big data, the method comprising the following steps:

[0015] (1) The system box is placed in the offline electricity payment hall. When users need to make self-service inquiries and payments, the two covers are opened to expose the display components. At the same time, the operation panel is unfolded, and the user places their ID on the operation panel for identity verification.

[0016] (2) The system selects the corresponding level of the secondary screen to rotate to the front and the main screen to rotate to the top of the secondary screen based on user information and previous electricity bill data.

[0017] (3) Obtain the user's historical electricity bill information and electricity bill information to be calculated; wherein, the historical electricity bill information includes: the user's annual electricity bill information, monthly electricity bill information and daily electricity bill information; according to the user type and the monthly electricity bill information, match and generate the user's monthly predicted electricity consumption trend;

[0018] (4) Based on the daily electricity consumption information, calculate the user’s daily electricity consumption habits, and combine the user’s monthly predicted electricity consumption trend to predict the user’s daily electricity consumption, thereby obtaining the user’s monthly predicted electricity cost; compare the monthly predicted electricity cost on the main screen with the electricity cost information to be calculated on the secondary screen to obtain the electricity cost calculation result.

[0019] (5) Regarding the calculation results, the accuracy of the calculation can be improved when the error is small, and when the error is large, staff can be asked to perform manual calculation in a timely manner to avoid errors.

[0020] The beneficial effects of this invention are:

[0021] 1. When the display component needs to be used, the present invention rotates the bidirectional screw, the screw block moves along the surface of the bidirectional screw, the connecting rod pushes the cover plate open, and at the same time, due to the telescopic pull rod, during the upward rotation of the cover plate, the telescopic pull rod pulls the vertical frame upward, and the first spring telescopic rod assists in lifting the vertical frame upward, so that the main screen and the secondary screen are fully exposed, making it convenient to use the main screen and the secondary screen to view electricity bill information and calculation results.

[0022] 2. This invention uses a first motor to rotate a first connecting shaft, a second socket, and a mounting shaft, causing the main screen to rotate and open from being attached to the sub-screen to the top of the sub-screen. One end of the mounting shaft is connected to a baffle at the tail end of the rotating frame via a transmission belt, so the upper baffle also rotates and opens. Through the meshing of transmission gears on the other side of the two baffles, the two baffles open synchronously in opposite directions, fully exposing the sub-screen. This facilitates the rotation of the second connecting shaft, the second socket, and the rotating frame's rotating shaft via the second motor. The corresponding sub-screen is adjusted to the front end according to the user's power consumption type. Through the data model built into the corresponding sub-screen, the user's power consumption trend can be simulated more quickly and accurately. The connection between the first transmission belt and the baffle and mounting shaft consists of large and small wheels. The small wheel is connected to the mounting shaft, and the large wheel is connected to the baffle, with the radii set proportionally. After the main screen is rotated 180 degrees, the cover plate rotates from covering the tilted sub-screen to a vertical position.

[0023] 3. In this invention, the bottom of the telescopic column can be drilled into the ground by fixing screws to maintain the stability of the device during drilling and ultrasonic detection. By rotating the second screw, the slide plate slides along the slide rail, raising the placement platform and insert plate from the rear end. The slip ring slides along the surface of the telescopic column, thereby adjusting the angle of the detection components to facilitate flaw detection of the surrounding rock surface at different angles.

[0024] 4. When the cover plate covers the top of the system box, the operation panel is also rotated to a vertical position. At this time, the elastic force of the second spring telescopic rod drives the vertical frame to move downward to cover the outside of the operation panel, avoiding damage to the recognition end and dust contamination. When the cover plate is opened again, the second transmission belt drives the first bevel gear and the second bevel gear mesh, the operation panel rotates synchronously, and pushes the vertical frame upward, so that the recognition end is close to the face. The operation panel rotates to a vertical position, which makes it convenient for people to place their ID cards to recognize personal information through the recognition end.

[0025] 5. Compared with the prior art, the present invention features a display component delivered from within the system box during user operation. After the system box identifies the user's identity information, it adjusts the corresponding secondary screen to the bottom of the main screen according to the user's previous electricity consumption level. The secondary screen is used to display a model derived from the customer's previous monthly electricity consumption records to predict the electricity consumption required for the current month. The main screen displays the current actual consumption value, allowing for a direct comparison between the two. This improves the accuracy of calculation when the error is small, and allows for timely manual calculation by staff when the error is large, thus avoiding errors. Attached Figure Description

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] Please see Figures 1 to 10 The present invention provides a technical solution:

[0039] A method for calculating electricity costs based on big data, the method comprising the following steps:

[0040] (1) The system box is placed in the offline electricity payment hall. When users need to make self-service inquiries and payments, the two covers are opened to expose the display components. At the same time, the operation panel is unfolded, and the user places their ID on the operation panel for identity verification.

[0041] (2) The system selects the corresponding level of the secondary screen to rotate to the front and the main screen to rotate to the top of the secondary screen based on user information and previous electricity bill data.

[0042] (3) Obtain the user's historical electricity bill information and electricity bill information to be calculated; wherein, the historical electricity bill information includes: the user's annual electricity bill information, monthly electricity bill information and daily electricity bill information; according to the user type and the monthly electricity bill information, match and generate the user's monthly predicted electricity consumption trend;

[0043] (4) Based on the daily electricity consumption information, calculate the user’s daily electricity consumption habits, and combine the user’s monthly predicted electricity consumption trend to predict the user’s daily electricity consumption, thereby obtaining the user’s monthly predicted electricity cost; compare the monthly predicted electricity cost on the main screen with the electricity cost information to be calculated on the secondary screen to obtain the electricity cost calculation result.

[0044] (5) Regarding the calculation results, the accuracy of the calculation can be improved when the error is small, and when the error is large, staff can be asked to perform manual calculation in a timely manner to avoid errors.

[0045] A big data-based electricity billing device includes a system box 1. The top two sides of the system box 1 are hinged and fitted with cover plates 11. A storage cavity 19 is located on the top of the system box 1, and a display component 2 is housed inside the storage cavity 19. The display component 2 includes a vertical frame 21. A rotating frame 27 is fixed to the inner side of the vertical frame 21. Three secondary screens 22 are equidistantly fixed to the rotating shaft surface of the rotating frame 27. A main screen 23 is mounted on the top of the vertical frame 21, and the main screen 23 and the lower secondary screens 22 are on the same plane. A mounting shaft 24 is fixed to the bottom of the main screen 23, and both ends of the mounting shaft 24 rotatably extend out of the vertical frame 21. Two first spring telescopic rods 110 are fixed to the bottom of the storage cavity 19, and the extended ends of the first spring telescopic rods 110 are fixedly connected to the bottom of the vertical frame 21. The front of the system box 1... The system box 1 is mounted on top of the control panel 3 via a rotating shaft, and a vertical frame 31 is slidably mounted on top of the control panel 3. The vertical frame 31 covers the outside of the vertically positioned control panel 3. The control panel 3 is connected to the cover plate 11. When using the device, the system box 1 is placed in an offline electricity payment hall. When the user needs to make a self-service inquiry and payment, the two covers 11 are opened, exposing the display component 2. At the same time, the control panel 3 is unfolded. The user places their ID on the control panel 3 for identity verification. The system selects the corresponding level of the secondary screen 22 to rotate to the front based on the user information and previous electricity bill data. The main screen 23 rotates to the top of the secondary screen 22. The main screen 23 displays the user's current electricity bill information, and the secondary screen 22 simulates and predicts the user's monthly electricity bill. The two are compared intuitively to determine the accuracy of the calculation result.

[0046] In this embodiment, a bidirectional screw 4 is rotatably mounted on the top of the back of the system box 1 via a bearing seat. Two screw blocks 41 are symmetrically threaded onto the surface of the bidirectional screw 4. A connecting rod 42 is rotatably mounted on the top of the screw blocks 41 via a rotating shaft. The other end of the connecting rod 42 is rotatably connected to the side of the cover plate 11 via a rotating shaft. A telescopic pull rod 14 is rotatably mounted on the inner surface of the cover plate 11 via a rotating shaft. The other end of the telescopic pull rod 14 is rotatably connected to the top of the vertical frame 21 via a rotating shaft. When the display component 2 needs to be used, the bidirectional screw 4 is rotated, and the screw blocks 41 move along the surface of the bidirectional screw 4. The connecting rod 42 pushes the cover plate 11 to open. At the same time, due to the telescopic pull rod 14, during the upward rotation of the cover plate 11, the telescopic pull rod 14 pulls the vertical frame 21 upward. The first spring telescopic rod 110 assists in lifting the vertical frame 21 upward, exposing the main screen 23 and the secondary screen 22, making it convenient to use the main screen 23 and the secondary screen 22 to view electricity bill information and calculation results.

[0047] In this embodiment, the display component 2 further includes baffles 211. Two baffles 211 are symmetrically mounted on the rear end of the rotating frame 27 via a rotating shaft, and the baffles 211 respectively cover the surfaces of the two rear sub-screens 22. One end of the mounting shaft 24 protrudes from the surface of the vertical frame 21 and is fitted with a first transmission belt 29. The other end of the first transmission belt 29 is rotatably and fixedly connected to the baffles 211 at the upper end of the rotating frame 27. A transmission gear 210 is mounted on the other end of the rotating frame 27 at the rotatable connection point of the two baffles 211. The two transmission gears 210 mesh and are fixedly connected to the rotating ends of the corresponding baffles 211. The top of the system box 1... A first motor 15 is fixed to the outer surface of one side baffle 211, and a first connecting shaft 16 is fixed to the output end of the first motor 15. The other end of the mounting shaft 24 extends through the vertical frame 21 and is fixed to a first socket 25. The first connecting shaft 16 is slidably inserted into the first socket 25. A second motor 17 is fixed to the outer surface of the cover plate 11 at the other end of the system box 1, and a second connecting shaft 18 is fixed to the output end of the second motor 17. The rotating shaft of the rotating frame 27 is fixed to a second socket 26, and the second connecting shaft 18 is slidably inserted into the second socket 26. Slots 28 are provided on the surfaces of both the first socket 25 and the second socket 26. The first connecting shaft 16 and the second connecting shaft 16 are fixed to the first connecting shaft 24. The surface of the second connecting shaft 18 is provided with a protruding strip. When the cover plate 11 is opened and the display component 2 is pulled upward to the highest point, the protruding strip of the first connecting shaft 16 slides into the slot 28 of the first socket 25, and the protruding strip of the second connecting shaft 18 is inserted into the slot 28 of the second socket 26. The rotation of the first motor 15 drives the first connecting shaft 16, the second socket 26, and the mounting shaft 24 to rotate, causing the main screen 23 to rotate and open from being attached to the sub-screen 22 to the top of the sub-screen 22. One end of the mounting shaft 24 is rotatably connected to the baffle 211 at the tail end of the rotating frame 27 via a transmission belt, so the upper baffle 211 will also rotate and open. The transmission gear 21 on the other side of the two baffles 211 is then connected. With the engagement of 0, the two baffles 211 open synchronously in opposite directions, fully exposing the sub-screen 22. This facilitates the rotation of the second connecting shaft 18, the second socket 26, and the rotating shaft of the rotating frame 27 via the second motor 17. The corresponding sub-screen 22 is adjusted to the front end according to the user's power consumption type. Through the data model built into the corresponding sub-screen 22, the user's power consumption trend can be simulated more quickly and accurately. The connection between the first transmission belt 29 and the baffles 211 and the mounting shaft 24 is divided into large and small wheels. The small wheel is connected to the mounting shaft 24, and the large wheel is connected to the baffle 211. The radii are set proportionally. After the main screen 23 is rotated 180 degrees, the cover plate 11 rotates from covering the inclined sub-screen 22 to a vertical position.

[0048] In this embodiment, second spring telescopic rods 34 are fixed on the outer walls of both sides of the system box 1, and the top of the second spring telescopic rods 34 is fixedly connected to the top two sides of the vertical frame 31. A collection end 33 is fixed on the outer surface of the vertical frame 31, and an identification end 32 is provided on the surface of the operation panel 3. A second bevel gear 37 is fixed at one end of the operation panel 3 that is rotatably connected to the system box 1, and a first bevel gear 36 is meshed with the outer side of the second bevel gear 37. The first bevel gear 36 is rotatably mounted on the surface of the system box 1 through a bearing seat. A second transmission belt 35 is fixed at the rear end of the first bevel gear 36, and the other end of the second transmission belt 35 carries... The wheel is fixedly sleeved on the rotating position of the cover plate 11. When the cover plate 11 covers the top of the system box 1, the operation panel 3 is also rotated to a vertical position. At this time, the elastic force of the second spring telescopic rod 34 drives the vertical frame 31 to move downward to cover the outside of the operation panel 3, so as to prevent the recognition end 32 from being damaged or contaminated by dust. When the cover plate 11 is opened again, the second transmission belt 35 drives the first bevel gear 36 and the second bevel gear 37 to mesh, the operation panel 3 rotates synchronously, and pushes the vertical frame 31 upward, so that the recognition end 32 is close to the face. The operation panel 3 rotates to a vertical position, which makes it convenient for people to place their ID cards through the recognition end 32 to identify personal information.

[0049] When using the device, the system box 1 is placed in the offline electricity payment hall. When users need to make self-service inquiries and payments, the bidirectional screw 4 is rotated, and the screw block 41 moves along the surface of the bidirectional screw 4. The connecting rod 42 pushes the cover plate 11 to open. At the same time, due to the telescopic pull rod 14, as the cover plate 11 rotates upward, the telescopic pull rod 14 pulls the vertical frame 21 upward. The first spring telescopic rod 110 assists in lifting the vertical frame 21 upward, exposing the main screen 23 and the secondary screen 22, making it convenient to use the main screen 23 and the secondary screen 22 to view electricity information and calculation results. When the cover plate 11 is open and the display component 2 is pulled upward to the highest point, the protrusion of the first connecting shaft 16 slides into place. Inside the slot 28 of the first socket 25, the protrusion of the second connecting shaft 18 is inserted into the slot 28 of the second socket 26. The rotation of the first motor 15 drives the first connecting shaft 16, the second socket 26, and the mounting shaft 24 to rotate, causing the main screen 23 to rotate from being attached to the sub-screen 22 to the top of the sub-screen 22. One end of the mounting shaft 24 is rotatably connected to the baffle 211 at the tail end of the rotating frame 27 via a transmission belt. Therefore, the upper baffle 211 also rotates and opens. Through the meshing of the transmission gear 210 on the other side of the two baffles 211, the two baffles 211 open synchronously in opposite directions, fully exposing the sub-screen 22, facilitating the rotation of the second connecting shaft 18 by the second motor 17. The rotating shafts of socket 26 and rotating bracket 27 rotate, adjusting the corresponding sub-screen 22 to the front end according to the user's power consumption type. Through the data model built into the corresponding sub-screen 22, the user's power consumption trend can be simulated more quickly and accurately. The connection between the first transmission belt 29, baffle 211, and mounting shaft 24 is divided into large and small wheels. The small wheel is connected to the mounting shaft 24, and the large wheel is connected to the baffle 211, with the radius set proportionally. After the main screen 23 is rotated 180 degrees, the cover plate 11 rotates from covering the inclined sub-screen 22 to a vertical position. At this time, the elastic force of the second spring telescopic rod 34 drives the vertical frame 31 to move downward to cover the outside of the operation panel 3, preventing damage to the recognition end 32. When the cover 11 is opened again after being contaminated by dust, the second transmission belt 35 drives the first bevel gear 36 and the second bevel gear 37 to mesh, the operation panel 3 rotates synchronously, and the vertical frame 31 is pushed upward, so that the recognition end 32 is close to the face. The operation panel 3 rotates to a vertical position, making it convenient for people to place their ID cards through the recognition end 32 to identify personal information. The system selects the corresponding level of the secondary screen 22 to rotate to the front based on the user information and previous electricity bill data, and the main screen 23 rotates to the top of the secondary screen 22. The main screen 23 displays the user's current electricity bill information, and the secondary screen 22 simulates and predicts the electricity bill that the user needs to pay this month. The two can be compared intuitively to know the accuracy of the calculation result.
