Description

Technical Field

[0001] The present invention belongs to the field of electric energy metering, and in particular relates to a balance acquisition method of a remote fee-controlled electric energy meter and a related system. Background Art

[0002] With the continuous advancement of the construction of new power systems, the volatility of user electricity loads has significantly increased, and electricity consumption has also increased significantly. At the same time, electricity prices are influenced by a variety of factors, including time, power supply structure, and regional economic development, showing a diversified and dynamic development trend. This complex electricity consumption environment and market-based electricity pricing mechanism have driven changes in electricity fee management models, making "local metering + remote fee control" an increasingly important means of electricity fee settlement in new power systems. To meet the national policy requirements for flexible adjustments to residential electricity prices, local power grid companies are gradually eliminating traditional local fee control models and actively promoting the transition from local fee control to remote fee control for smart electricity meters. This is aimed at popularizing remote fee control capabilities and improving the level of intelligent power grid management.

[0003] Currently, there are two main technical paths to achieve “cost-effectiveness and long-term improvement”: The first is to directly replace the electricity meter by replacing the original electricity meter that uses the local fee control mode with a smart electricity meter that supports remote fee control; The second is to adjust the parameters of the existing local fee-controlled electricity meter and switch its working mode to remote fee control, so that the function can be upgraded without replacing the hardware equipment.

[0004] With the full implementation of remote fee control, the meter's display will no longer display the balance page, but will instead focus on displaying electricity consumption data and real-time electricity usage. However, for some users, especially elderly users who lack access to online tools, it is crucial to keep track of their meter balance so they can pay their bills on time and avoid power outages that could disrupt their lives and operations. Traditional users, accustomed to checking their meter balance, will find the disappearance of the balance page disruptive, potentially impacting their ability to timely check and monitor their balance, increasing the risk of power outages and causing disruption to their lives and operations. Summary of the Invention

[0005] The purpose of the present invention is to provide a balance acquisition method and related system for a remote fee-controlled electricity meter to solve the technical problem that after the modification, the screen display content of the electricity meter will no longer display the balance page, and some users cannot query the balance at the electricity meter end.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a method for obtaining a balance of a remote fee-controlled electric energy meter, comprising: Obtain the current day's remaining amount and the previous day's remaining amount of the remote fee-controlled electricity meter to be queried in the master station; Update the electricity meter balance based on the remaining amount on the current day and the remaining amount on the previous day; The user inserts the card into the remote fee-controlled electricity meter to be queried, and the balance is displayed on the remote fee-controlled electricity meter to be queried.

[0007] A further improvement of the present invention is that the step of updating the electric energy meter balance according to the current day's remaining amount and the previous day's remaining amount specifically includes: If the remaining balance on the current day is greater than the remaining balance on the previous day, the difference between the remaining balance on the previous day and the remaining balance on the current day is obtained. The master station recharges the remote fee-controlled energy meter to be queried based on the difference in balance, and sends the recharged amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried. If the remaining balance on the current day is less than the remaining balance on the previous day, the master station will issue a remote recharge and refund instruction, and send the synchronized updated amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried; If the remaining balance on the current day is equal to the remaining balance on the previous day, no operation will be performed.

[0008] A further improvement of the present invention is that: in the step of the master station issuing the remote recharge and refund instruction, the recharge amount is the minimum recharge amount.

[0012] A further improvement of the present invention is that the step of updating the electric energy meter balance according to the remaining amount on the current day and the remaining amount on the previous day specifically includes: If the remaining balance on the current day is greater than the remaining balance on the previous day, the difference between the remaining balance on the previous day and the remaining balance on the current day is obtained. The master station recharges the remote fee-controlled energy meter to be queried based on the difference in balance, and sends the recharged amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried. If the remaining balance on the current day is less than the remaining balance on the previous day, the master station will issue a remote recharge and refund instruction, and send the synchronized updated amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried; If the remaining balance on the current day is equal to the remaining balance on the previous day, no operation will be performed.

[0013] A further improvement of the present invention is that: in the step of the master station issuing the remote recharge and refund instruction, the recharge amount is the minimum recharge amount.

[0014] A further improvement of the present invention is that the minimum recharge amount is 0.01 yuan.

[0015] A further improvement of the present invention is that the step of the master station issuing the remote recharge and refund instruction specifically includes: The user's daily electricity consumption is obtained and the daily electricity bill is calculated. The master station issues a remote recharge and refund instruction based on the daily electricity bill. The refund amount is the sum of the minimum recharge amount and the daily electricity bill.

[0016] In a third aspect, the present invention provides an electronic device comprising a memory and a processor, wherein the memory stores a computer program, and is characterized in that when the processor executes the computer program, it implements the steps of the method for obtaining the balance of a remote cost-controlled electricity meter.

[0017] In a fourth aspect, the present invention provides a storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method for obtaining the balance of a remote cost-controlled electricity meter.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a method for obtaining the balance of a remote fee-controlled energy meter, comprising: obtaining the current day's remaining balance and the previous day's remaining balance of the remote fee-controlled energy meter to be queried in a master station; if the current day's remaining balance is greater than the previous day's remaining balance, obtaining the difference between the previous day's remaining balance and the current day's remaining balance; the master station recharging the remote fee-controlled energy meter to be queried based on the difference in balance, and sending the recharged amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried; if the current day's remaining balance is less than the previous day's remaining balance, the master station issuing a remote recharge and refund instruction, and sending the synchronized updated amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried; if the current day's remaining balance is equal to the previous day's remaining balance, no operation is performed; a user inserts a card into the remote fee-controlled energy meter to be queried, and the balance is displayed in the remote fee-controlled energy meter to be queried.

DETAILED DESCRIPTION

[0020] In order to further understand the content of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0021] This invention is applicable to modifying and reducing the remaining balance on an electricity meter, i.e., refunding electricity meters. Due to the requirements of the 13th and 20th editions of the electricity meter safety regulations, refunds can only be performed after recharging. Therefore, when the current day's remaining balance on the electricity meter is less than the previous day's remaining balance, a "recharge first, then refund" process is required to synchronize the remaining balance with the marketing system.

[0022] Cancellation of local fee control function: To implement remote fee control mode, the local fee control function of the local fee-controlled energy meter is hidden, which mainly involves local tripping and closing, electricity fee recharge and deduction, local alarm and other functions. To cancel the local fee control function, the present invention proposes a method to achieve zero local electricity price through parameter setting, thereby canceling the local billing function of the energy meter; in addition, to prevent the energy meter from triggering local tripping, the relevant alarm parameters are set, solving the problem of users being unable to close the circuit breaker after a local trip.

[0023] Cancel the display of electricity price parameters: After the local fee control mode is switched to the remote fee control mode, the original tiered electricity price, rate electricity price and other information are invalid. In order to completely switch to the remote mode, other screen display content is set to replace the electricity price, remaining amount and other information, so that the electricity meter is completely in the local metering only mode and the electricity fee is calculated remotely based on the metering data. The relevant amount is recharged through the main station system, and users can recharge online, which improves the convenience of users purchasing electricity.

[0024] Remaining balance in the meter: After switching from a local cost-controlled energy meter to remote cost-controlled mode, handling the remaining balance in the meter becomes a challenge. After switching to remote cost-controlled mode, the remaining balance in the meter will no longer be automatically deducted, and the user's remaining balance will be transferred to the master station system for centralized management.

[0025] In order to quickly complete the conversion of the local remaining balance and maintain the user's remaining balance through the master station system, the present invention proposes a method for effectively clearing the local remaining balance. The specific scheme is as follows: the master station obtains the user's daily electricity consumption and calculates the electricity bill, issues a remote recharge command for the correct number of electricity purchases, and the recharge amount is 0.01, then issues a remote refund command for the correct number of electricity purchases, and the refund amount is (0.01 + the daily consumption amount), and so on, until the remaining balance in the meter is 0.

[0026] When the local fee-controlled electricity meter switches to the remote fee-controlled mode, the LCD can no longer display the current actual remaining amount. The present invention proposes a method for querying the balance using the user's electricity purchase card. When the user wants to query the meter, the card can be inserted into the meter. After the card meter is successfully read, the current remaining amount can be displayed. Therefore, under the condition that the remaining amount of the remote fee-controlled electricity meter is 0, the main station sends the parameters of the remaining amount to the electricity meter at that time, and updates it every day; therefore, the present invention provides a method for obtaining the balance of a remote fee-controlled electricity meter, so that the user can query the amount updated by the main station for the electricity meter every day by inserting the card on the electricity meter, which brings convenience to the life and production and operation of traditional users.

[0027] Example 1: See also Figure 1 A method for obtaining the balance of a remote fee-controlled electric energy meter comprises the following steps: S1, obtain the current day's remaining amount and the previous day's remaining amount of the remote fee-controlled electricity meter to be queried in the master station; S2, updating the electric energy meter balance based on the remaining amount on the current day and the remaining amount on the previous day; In a specific embodiment, the step of updating the electric energy meter balance according to the current day's remaining amount and the previous day's remaining amount specifically includes: S21, if the remaining balance on the current day is greater than the remaining balance on the previous day, the difference between the remaining balance on the previous day and the remaining balance on the current day is obtained, the master station recharges the remote fee-controlled energy meter to be queried based on the difference in balance, and sends the recharged amount to the remote fee-controlled energy meter to be queried; S22: If the remaining balance on the current day is less than the remaining balance on the previous day, the user's daily electricity consumption is obtained and the daily electricity fee is calculated. The master station issues a remote recharge and refund instruction based on the daily electricity fee. The refund amount is the sum of the daily electricity fee and the simulated recharge amount of the master station. The remaining balance in the meter is synchronously updated every day, and the synchronized updated amount is sent to the remote fee-controlled electricity meter to be queried. In a specific embodiment, if the remaining balance on the current day is less than the remaining balance on the previous day, the data collection master station, after obtaining the user's electricity bill for the current day, implements a "one-charge-one-refund" strategy, i.e., a remote recharge followed by a refund operation: the refund amount is the sum of the electricity bill consumed on the current day and the simulated recharge amount at the master station, thereby achieving a daily synchronous update of the remaining balance in the meter; The "Recharge, Refund" strategy applies to modifying and reducing the remaining balance on an energy meter, i.e., refunding energy meter bills. Due to the 13th and 20th editions of the energy meter safety regulations, refunds can only be performed after recharging. Therefore, if the current day's remaining balance on the energy meter is less than the previous day's, a "recharge first, then refund" strategy is required to synchronize the remaining balance with the marketing system.

[0028] S23: If the remaining amount on the current day is equal to the remaining amount on the previous day, no operation will be performed; S3, the user inserts the card into the remote fee-controlled electricity meter to be queried, and the balance is displayed on the remote fee-controlled electricity meter to be queried.

[0029] Example 2: See also Figure 2 , a balance acquisition system in a remote fee control mode, comprising: The data acquisition module is used to obtain the remaining amount of the remote fee-controlled electric energy meter to be queried on the master station on the current day and the remaining amount of the previous day; The remaining balance update module is used to update the balance of the electric energy meter based on the remaining balance of the current day and the remaining balance of the previous day; Remote fee-controlled electricity meter, used to display the balance after the user inserts the card.

[0030] In a specific embodiment, the step of updating the electric energy meter balance according to the remaining amount on the current day and the remaining amount on the previous day specifically includes: If the remaining balance on the current day is greater than the remaining balance on the previous day, the difference between the remaining balance on the previous day and the remaining balance on the current day is obtained. The master station recharges the remote fee-controlled energy meter to be queried based on the difference in balance, and sends the recharged amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried. If the remaining balance on the current day is less than the remaining balance on the previous day, the master station will issue a remote recharge and refund instruction, and send the synchronized updated amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried; If the remaining balance on the current day is equal to the remaining balance on the previous day, no operation will be performed.

[0031] Example 3: After the local fee-controlled energy meter switches to remote fee-controlled mode, the remaining balance in the meter will no longer be automatically deducted, and the user's remaining balance will be transferred to the master station system for unified management. In order to implement the remote fee-controlled mode, it is first necessary to hide the local fee-controlled energy meter's local fee-controlled function, which mainly involves local tripping and closing, electricity charge and deduction, local alarm and other functions. In order to cancel the local fee-controlled function, this embodiment proposes a method of setting the local electricity price to zero through parameter settings, thereby canceling the local billing function of the energy meter. When it is necessary to clear the remaining balance of the energy meter, the specific method is as follows: Obtain the user's daily electricity consumption and calculate the electricity bill for the day; According to the electricity bill of the day, issue the required number of remote recharge commands; Based on the current day's electricity bill and the required number of remote recharge commands, a remote refund instruction is issued until the remaining amount is 0.

[0032] Traditional zeroing methods may require on-site operations or complex instructions. This method can be used to complete the operation remotely, significantly shortening the zeroing time and improving work efficiency. This function can meet the balance zeroing needs in specific situations, such as when the user changes accounts, replaces a faulty electricity meter, ends the settlement cycle, or cleans up the system, thereby enhancing system flexibility. This embodiment ensures that the user balance status is synchronized with the background system data through automated processing of the zeroing logic, avoiding data asynchrony problems caused by manual zeroing. Remote zeroing does not require manual intervention, reducing operational errors or disputes caused by manual zeroing, and improving the accuracy and standardization of operations. This method has clear logic and is easy to implement. It can be extended to other fee control systems with similar needs and has good versatility and scalability.

[0033] Example 4: In order to prevent the electric energy meter from triggering a local trip, this embodiment needs to set the relevant alarm parameters, thereby solving the problem that the user cannot close the circuit breaker after a local trip.

[0034] Read whether the local fee control parameters in the electricity meter are the set values. If not, obtain the current fee control parameters and send them to the electricity meter.

[0035] This embodiment checks whether the local cost control parameters in the electricity meter are consistent with the set values, thereby avoiding cost control function anomalies caused by parameter asynchrony and ensuring that the system and the electricity meter maintain a consistent working state. Timely detection and correction of cost control parameter anomalies helps avoid possible billing errors or functional failures, ensuring the normal operation of the system and service reliability. This embodiment realizes automatic calibration of parameters through a reading and issuing mechanism, reducing the complexity of manual operations, the workload of operation and maintenance personnel, and the possibility of human error. This embodiment adds dynamic verification and synchronization functions for cost control parameters, making the entire system more intelligent and automated, and improving the management capabilities of modern cost control systems.

[0036] Example 5: After the local fee control mode is switched to the remote fee control mode, the original tiered electricity prices, rate electricity prices and other information are invalid. In order to completely switch to the remote mode, other screen display content is set to replace the electricity price, remaining amount and other information, so that the electricity meter is completely in the local metering only mode and the electricity fee is calculated remotely based on the metering data. The relevant amount is recharged through the main station system, enabling users to recharge online and improving the convenience of users purchasing electricity.

[0037] See also Figure 3In the early morning of April 16, the user's remaining balance in the synchronous marketing system of the main collection station was 110.40 yuan. The user's remaining balance the previous day was 113.56 yuan. The calculated electricity fee for the user on April 15 was 3.16 yuan. In the early morning of April 16, the main collection station needed to recharge the user 0.01 yuan and then refund 3.17 yuan. Therefore, when the user inserted the card to check the remaining balance on the electricity meter on April 16, it was 110.40 yuan. Example 6: In order to quickly complete the conversion of the local remaining balance and maintain the user's remaining balance through the master station system, this embodiment includes an electricity meter clearing module for obtaining the user's daily electricity consumption and calculating the daily electricity bill; issuing a required number of remote recharge commands based on the daily electricity bill; and issuing a remote refund instruction based on the daily electricity bill and the required number of remote recharge commands until the remaining balance is 0.

[0038] Example 7: In order to prevent the electric energy meter from triggering a local trip, the relevant alarm parameters need to be set, which solves the problem that the user cannot close the circuit breaker when a local trip occurs. This embodiment includes a fee control parameter sending module for obtaining the current fee control parameters and sending the current fee control parameters to the electric energy meter.

[0039] Changing the local cost-controlled energy meter to remote cost-controlled mode can better meet user electricity needs and improve service quality. Furthermore, the switching scheme designed in this invention ensures that the energy meter can smoothly switch cost-controlled modes without affecting user electricity consumption during the switching process, thus ensuring the quality of the energy meter mode switching.

[0040] Example 8: See also Figure 4 ,The master station communicates with the electricity meter, reads the balance in the ,meter and combines it with local control parameters such as the ,day's electricity price and tiered electricity price to calculate the day's electricity ,charge.

[0041] Verify whether the electricity price parameters, step control parameters, etc. currently stored in the electricity meter are consistent with the preset values. If not, update the parameter configuration of the local electricity meter to ensure consistency with the master station.

[0042] Check the remaining balance in the electricity meter. If the balance is greater than 0, continue the operation; if the balance is insufficient, the process terminates and waits for the balance to be updated.

[0043] Based on the balance and the current day's electricity bill calculated in real time, if the balance is sufficient, a closing command is issued to allow power to be supplied. If the balance is insufficient, a tripping command is issued to disconnect the power supply.

[0044] Send the modified screen display item parameters to the electricity meter. If there are parameters that need to be adjusted, such as screen display items or other electricity meter function parameters, the master station will update them to the electricity meter through instructions.

[0045] Verify whether the local parameters are consistent with the set values, and re-verify whether the local margin and parameters in the electricity meter are consistent with the master station settings to ensure consistency; if the parameters are inconsistent, it is necessary to record the abnormality or readjust.

[0046] The user purchases electricity through remote recharge, and the master station sends an instruction to the electricity meter with the purchase amount of "0.01 yuan".

[0047] Determine whether the remote recharge balance is the original amount + 0.01 yuan, and verify whether the balance after recharge is the original balance plus the recharge amount. If they are consistent, proceed to the next step; if not, it may prompt that the recharge failed or recharge.

[0048] Determine whether the remote balance is the current day's electricity bill + 0.01 yuan. The master station dynamically updates the balance and adjusts the balance to "the current day's electricity bill + 0.01 yuan." If the balance meets the rules, proceed to the next step. If the balance is abnormal, recheck or prompt the user.

[0049] Determine whether the remote balance is the current day's electricity bill - 0.01 yuan, adjust the current day's electricity bill deduction operation, and update the balance to "current day's electricity bill - 0.01 yuan". If the adjustment is successful, proceed to the next step; if the adjustment fails, you may need to record or retry.

[0050] Check whether the remote balance has been reset to zero. If it is, the process is complete. If not, re-execute the master station's instruction to send the meter a purchase amount of "0.01 yuan." The meter reads the amount from the card and stores it in the meter's balance.

[0054] The memory 101 in the electronic device 100 stores a plurality of instructions to implement a method for obtaining a balance of a remote fee-controlled electric energy meter. The processor 102 may execute the plurality of instructions to implement: Obtain the current day's remaining amount and the previous day's remaining amount of the remote fee-controlled electricity meter to be queried in the master station; If the remaining balance on the current day is greater than the remaining balance on the previous day, the difference between the remaining balance on the previous day and the remaining balance on the current day is obtained. The master station recharges the remote fee-controlled energy meter to be queried based on the difference in balance, and sends the recharged amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried. If the remaining balance on the current day is less than the remaining balance on the previous day, the master station will issue a remote recharge and refund instruction, and send the synchronized updated amount to the remote fee-controlled energy meter to be queried to update the balance of the remote fee-controlled energy meter to be queried; If the remaining amount on the current day is equal to the remaining amount on the previous day, no operation will be performed; The user inserts the card into the remote fee-controlled electricity meter to be queried, and the balance is displayed on the remote fee-controlled electricity meter to be queried.
