Description

Technical Field

[0001] The invention relates to the technical field of electricity management, in particular to a prepayment system for electricity management. Background Art

[0002] In the current environment of power supply and management, with the continuous development of the power market and the growing demand of users, the traditional post-payment model has gradually exposed its limitations. This model relies on users to pay at fixed monthly or annual payment times, which leads to huge capital recovery pressure and management costs for power companies when collecting electricity bills. In addition, manual meter reading is not only inefficient, but also easily affected by human factors, resulting in inaccurate data and charging disputes.

[0003] Existing power management technologies mainly rely on manual meter reading and post-charging mechanisms, which have obvious drawbacks. First, the meter reading process is time-consuming, labor-intensive and error-prone, increasing the operating costs of power supply companies. Second, arrears are common, and users often default on their electricity bills, putting pressure on the power company's cash flow. In addition, the lack of effective power consumption monitoring and data analysis means that the allocation and use of power resources are inefficient.

[0004] In view of the above problems, how to ensure the stable operation, data security and seamless connection of prepaid metering control devices with the existing power grid system has become a new technical challenge. In particular, further technical optimization and improvement are needed to ensure the security of user electricity purchase information and prevent electricity fee leakage and electricity theft. Summary of the invention

[0005] The purpose of the present invention is to provide a prepaid electricity management system to solve the new technical challenges of ensuring the stable operation of the prepaid metering control device, data security and seamless connection with the existing power grid system, especially in terms of ensuring the security of user electricity purchase information, preventing electricity fee loss and electricity theft.

[0029] Compared with the prior art, the electricity management prepayment system using the above technical solution has the following beneficial effects:

[0030] 1. The system greatly improves the efficiency of power management through automated power measurement, billing and power outage control. It reduces the workload of manual meter reading, billing and collection, and reduces management costs. Real-time data analysis and remote monitoring functions enable power suppliers to understand users' power consumption in a timely manner, so as to respond quickly and optimize power distribution and supply strategies;

[0031] Second, users can easily enter prepaid information and check remaining power and fees through the user interface, providing a convenient and autonomous service experience. The alarm prompt system will sound and light alarms when the user's power consumption is close to the prepaid limit. This timely reminder allows users to have enough time to purchase electricity and avoid the inconvenience caused by sudden power outages;

[0032] 3. The power usage data collected by the dedicated transformer collection terminal provides rich information for energy efficiency analysis. By analyzing these data, high-energy-consuming equipment or unreasonable power usage behaviors can be identified, so that measures can be taken to optimize energy conservation. The system can also intelligently adjust the power supply according to the user's power usage habits and needs, reduce energy waste, and improve overall energy utilization efficiency.

[0033] 4. The data protection unit automatically protects prepaid information and power usage data after power input is interrupted, ensuring that the data can be stored for more than 10 years even without power. This protection mechanism prevents data loss and tampering, and guarantees the data security and rights of users. In addition, the system also protects user data from unauthorized access and leakage through technical means such as encrypted communication and access control.

[0034] 5. The components in the system, such as isolating switches, AC contactors, intermediate relays, indicator lights, miniature circuit breakers and leakage circuit breakers, together form a comprehensive electrical safety protection network. They can quickly cut off the power supply when an abnormality occurs in the circuit, prevent electrical faults such as overload, short circuit, leakage, etc., and ensure the safety of equipment and personnel. This safety mechanism not only reduces the probability of power accidents, but also reduces the potential risk of property losses and personal injuries.

[0035] 6. Through the GPRS communication module, the system can communicate with the remote management center in two directions to achieve remote monitoring and management functions. This allows power suppliers to monitor the status of multiple prepaid distribution control systems in a centralized location and discover and solve problems in a timely manner. Remote management also allows suppliers to adjust prepaid parameter settings and control commands based on real-time data, and flexibly respond to market changes and dynamic changes in user needs.

[0036] 7. The system is designed with consideration of power management scenarios of different scales and needs, and is highly adaptable and scalable.

[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] like Figure 1-Figure 4As shown, a prepayment system for electricity management includes a prepayment metering control device, a user operation interface, a communication module, a controller, and at least one power output terminal;

[0043] Wherein, the prepayment metering control device is electrically connected to the power output terminal and is used to control the power output;

[0044] The user operation interface is used to receive prepaid information input by the user;

[0045] The communication module is used for communicating with the remote management center;

[0046] The controller is electrically connected to the prepayment metering control device, the user operation interface and the communication module, and is used for processing the prepayment information and controlling the prepayment metering control device to control the power output according to the prepayment information.

[0047] The prepaid metering control device further comprises: an electricity measurement unit, a billing unit and a power failure control unit;

[0048] The current transformer is located in the power measurement unit (not shown in the current transformer figure), which is directly connected to the power output terminal. It is used to measure the current passing through the power output terminal in real time and provide this data to the billing unit for billing processing. In the power measurement unit, the current transformer is the first component that contacts the current from the power output terminal. It accurately measures these currents and converts the measurement results into digital signals for use by the billing unit.

[0049] The power measurement unit is used to measure the power flowing through the output end of the power supply and send the measurement result to the billing unit;

[0050] The billing unit calculates the fee based on the prepaid information and the power usage, and sends a signal to the power-off control unit when the fee reaches the prepaid amount;

[0051] The power-off control unit is used to cut off the power output of the power output terminal after receiving a signal.

[0052] The communication module communicates with the remote management center via GPRS, receives prepaid parameter settings and control commands from the management center, and sends status information of the prepaid power distribution control system to the management center.

[0053] It also includes a special transformer collection terminal, which is electrically connected to the prepaid metering control device and the communication module, and is used to collect power usage data at the power output end, and send the collected data to a remote management center through the communication module.

[0054] Among them, the dedicated transformer acquisition terminal can be set and queried by the remote management center for the terminal group address, terminal configuration and configuration parameters, communication parameters, etc., and the terminal ID can be queried;

[0055] The dedicated transformer collection terminal communicates with the electric energy meter via RS485, and collects and stores the electric energy meter data at the set collection interval.

[0056] It also includes a data protection unit for automatically protecting prepayment information and energy usage data after power input is interrupted, ensuring that the data is retained for more than 10 years without power.

[0057] It also includes an alarm prompt system for issuing an audible and visual alarm when the user's electricity consumption approaches the prepaid quota, prompting the user to purchase electricity.

[0058] Among them, the power output end further includes: an isolating switch, an AC contactor, an intermediate relay, an indicator light, a miniature circuit breaker, and a leakage circuit breaker;

[0059] The isolating switch is electrically connected to the power output terminal and is used to isolate the power supply to ensure that the equipment can be maintained or replaced in a safe state;

[0060] The AC contactor is connected to the isolating switch and is used to control the power output of the power output terminal and cut off or connect the power supply according to the prepayment information and the signal of the billing unit;

[0061] The intermediate relay is electrically connected to the miniature circuit breaker and the leakage circuit breaker through the AC contactor, and is used to expand the control capability of the controller and realize the control of multiple power output terminals;

[0062] The indicator light is electrically connected to the miniature circuit breaker through the AC contactor to display the working status of the system, such as whether the power output is normal, whether the prepaid amount is close, etc.

[0063] The miniature circuit breaker is electrically connected to the intermediate relay and indicator light to protect the system from overload and short circuit, ensuring safe and stable operation of the system.

[0064] The leakage circuit breaker is electrically connected to the intermediate relay to detect and protect the system from leakage and ensure personal safety.

[0065] In use, the user first enters the prepayment information through the user interface, which usually includes the amount of electricity or money purchased. The user interface transmits this information to the controller in the form of digital signals. The controller receives and processes this prepayment information, sets the user's prepayment limit, and initializes various system parameters to ensure that the system operates according to the user's needs.

[0066] The power measurement unit is a key part of the system. It measures the amount of electricity flowing through the power output in real time. This measurement is based on the accurate readings of the current transformer and the voltage sensor. The measured power data is converted into a digital signal and sent to the billing unit in real time. The billing unit calculates the fee based on the user's prepaid information and the actual power usage. During this process, the billing unit updates the user's remaining prepaid amount in real time. When the fee calculated by the billing unit reaches the user's preset prepaid amount, it immediately sends a signal to the power-off control unit to prevent the user from continuing to use electricity without paying the additional fee.

[0067] The power-off control unit is a key component for implementing power management. After receiving the signal from the billing unit, it immediately cuts off the power output of the power output terminal. If the user's power consumption does not exceed the prepaid quota, the power-off control unit remains off and the system continues to supply power normally. This control mechanism ensures the fairness and security of power supply and prevents theft and abuse of power.

[0068] The communication module communicates with the remote management center in two-way via GPRS. This allows the system to be remotely monitored and managed. The communication module not only receives prepaid parameter settings and control commands from the management center, but also adjusts system settings according to the requirements of the management center. In addition, the communication module also sends the status information of the prepaid power distribution control system (such as remaining power, used power, etc.) to the management center for real-time monitoring and data analysis.

[0069] The dedicated transformer acquisition terminal is responsible for collecting the power usage data at the power output end. These data include key parameters such as current, voltage, and power factor. The collected data is sent to the remote management center through the communication module. In the management center, these data can be used for load analysis, energy consumption management, and billing. This data collection and transmission mechanism provides rich data support for the optimization of the power system and helps improve energy utilization efficiency.

[0070] The data protection unit is an important component to ensure the security of user data. It can automatically protect prepayment information and power usage data after the power input is interrupted. This protection is achieved through a built-in backup power supply and data storage mechanism, ensuring that data can be preserved for more than 10 years even in the absence of power. This design guarantees the security and integrity of user data and prevents the risk of data loss and tampering.

[0071] When the user's electricity consumption approaches the prepaid quota, the alarm prompt system will sound an audible and visual alarm to remind the user to purchase electricity. This timely reminder not only helps users avoid sudden power outages, but also promotes users' self-management of electricity consumption.

[0072] The system includes isolating switches, AC contactors, intermediate relays, indicator lights, miniature circuit breakers and leakage circuit breakers, which together ensure the electrical safety and stable operation of the system. These components play a protective role in the circuit to prevent electrical faults such as overload, short circuit and leakage, thereby protecting the safety of equipment and personnel.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
