Description

Technical Field

[0001] The present invention relates to the technical field of financial systems, and in particular to a method and device for calculating electricity charges based on big data. Background Art

[0002] Electricity bill accounting, as a core component of electricity bill management, falls under product lifecycle management, including product data management and product process management. It adheres to smart contracts and business rules. The quality of its accounting directly impacts the normal operation of the power supply department's power marketing business and is crucial to the sustainable development of power companies. Traditional electricity bill accounting relies primarily on manual work. After a user's electricity bill is generated, manual checks are performed to determine whether the bill is incorrect, whether there are any anomalies, and whether any user information has changed. This results in low accounting efficiency. With the advancement of technology, automated electricity bill accounting using computers has gradually developed. However, this essentially transfers some manual operations to computers, such as anomaly checks, user information change checks, correct electricity bill calculations, and successful billing. It does not perform electricity bill accounting from the user's perspective, making it impossible to collect user electricity usage information through electricity bill accounting to provide better data support for subsequent power marketing operations.

[0003] In the existing technology, when users check their electricity bills offline, they can check and pay them on self-service devices. However, in this process, it is difficult for people to know how their electricity bills are actually calculated and the accuracy of the calculation process, and it is impossible to better display the calculation process to dispel users' doubts.

After the system box recognizes the user's identity information, it adjusts the corresponding sub-screen to the bottom of the main screen according to the user's previous electricity consumption level. The sub-screen is used to display a model derived from the customer's previous monthly electricity consumption records to predict the electricity consumption for the current month. The main screen displays the current actual consumption value. The two are compared intuitively. When the error is small, the accuracy of the calculation can be improved. When the error is large, staff can be sought in time for manual calculation to avoid errors.

[0019] (5) For the accounting results, if the error is small, the accuracy of the accounting can be improved. If the error is large, staff can be promptly sought to perform manual accounting to avoid errors.

[0020] Beneficial effects of the present invention:

[0021] 1. When the display assembly needs to be used, the bidirectional screw is rotated, the screw block moves along the surface of the bidirectional screw, and the connecting rod pushes the cover to open. At the same time, due to the telescopic pull rod, when the cover rotates upward, the telescopic pull rod pulls the vertical frame upward, and the first spring telescopic rod assists in lifting the vertical frame upward, exposing the main screen and the auxiliary screen, making it convenient to use the main screen and the auxiliary screen to view electricity fee information and accounting results.

[0022] 2. The present invention drives the first connecting shaft, the second socket and the installation shaft to rotate by the rotation of the first motor, so that the main screen rotates and opens from being attached to the secondary screen to the top of the secondary screen, and one end of the installation shaft is rotatably connected to the baffle at the tail end of the rotating frame through a transmission belt, so that the upper baffle will also rotate and open, and through the engagement of the transmission gears on the other sides of the two baffles, the two baffles are synchronously opened in opposite directions, exposing the entire secondary screen, making it convenient to drive the second connecting shaft, the second socket and the rotating shaft of the rotating frame to rotate by the second motor, and adjust the corresponding secondary screen to the front end according to the user's electricity consumption type. Through the built-in data model of the corresponding secondary screen, the user's electricity consumption trend can be simulated more quickly and accurately. The connection between the first transmission belt, the baffle and the installation shaft is divided into large and small wheels, the small wheel is connected to the installation shaft, and the large wheel is connected to the baffle, and the radii are set proportionally. After the main screen is flipped one hundred and eighty degrees, the cover plate rotates from covering the inclined secondary screen to a vertical shape.

[0023] 3. The bottom of the telescopic column in the present invention can be drilled into the ground through a fixed screw to maintain the stability of the device during drilling and ultrasonic detection. By rotating the second screw, the slide slides along the slide rail, raising the placement table and the plug plate from the rear end, and the slip ring slides along the surface of the telescopic column, thereby adjusting the angle of the detection assembly to facilitate flaw detection at different angles when drilling into the surrounding rock surface.

[0024] 4. When the cover of the present invention covers the top of the system box, the operation panel is also rotated to a vertical state. 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, so as to prevent the recognition end from being damaged and contaminated by dust. When the cover is opened again, the second transmission belt is driven, the first bevel gear is engaged with the second bevel gear, the operation panel rotates synchronously, and the vertical frame is lifted upward. The recognition end is close to the face of the person, and the operation panel is rotated to a vertical state, which is convenient for people to place the identity document through the recognition end to identify personal information.

[0025] 5. Compared with the prior art, the present invention is characterized in that the display component is sent out from the system box when the user is in use. After the system box recognizes the user's identity information, it adjusts the corresponding sub-screen to the bottom of the main screen according to the user's previous power consumption level. The sub-screen is used to display a model derived from the customer's previous monthly power consumption records to predict the power consumption for the current month. The main screen displays the current actual consumption value. The two are compared intuitively. When the error is small, the accuracy of the calculation can be improved. When the error is large, staff can be promptly sought for manual calculation to avoid errors. BRIEF DESCRIPTION OF THE DRAWINGS
