Content description

The invention relates to the technical field of smart electric meters, in particular to a new type of smart electric energy meter based on super capacitor power supply.

Background of the invention

As a terminal device in the smart grid, smart meters provide a solid foundation for the operation of the entire system, and can provide a reasonable framework for new resources. Solar and wind energy can be reasonably optimized through smart meters, and real-time load prediction and optimization based on collected data ; Able to integrate and optimize distributed energy. The power supply department uses smart meters to monitor and control the overall power distribution system, understand the operation of the grid at the first time, optimize the energy framework, and provide economic and safe electrical energy; Improve the load forecast, understand the power demand of users, use smart meters to summarize all users' power demand, which can adjust the predicted load more quickly, improve the utilization rate, and economic benefits; it can timely transmit analysis and countermeasures for problems, and use smart meters to respond to users. The electricity consumption can be monitored and early warning in the first time, online analysis of various abnormal information, and tracking and control, when the cause of the failure is, call the information in the smart meter to quickly find the problem.

When a power failure occurs, the battery of the existing smart meter can only maintain the power supply of the clock circuit, and due to the long-term use of the battery, the failure rate is high, and the clock circuit cannot work normally, resulting in large errors in the meter clock after the power supply is restored. In addition, after a power outage occurs, the smart meter and communication module will be powered off, and malfunctions such as repairs cannot be performed.

Summary of the invention

In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a new type of smart electric energy meter based on super capacitor power supply, which can solve the problem of active fault repair work after external power failure.

The purpose of the present invention is achieved through such a technical solution, a new type of smart electric energy meter based on super capacitor power supply, which includes: switching power supply unit, energy storage unit, communication module, the basic unit of the electric meter; the basic unit of the switching power supply unit and the electric meter Unit connection, the switching power supply unit provides power for the basic unit of the electric meter; the switching power supply unit is also connected with the energy storage unit, and the switching power supply unit provides power for the energy storage unit; the basic unit of the electric meter is also connected with the communication module to realize the interactive communication of the smart energy meter; The energy storage unit is connected with the communication module, and the energy storage unit can be used to supply power to the communication module. Further, the switching power supply unit includes an AC-DC conversion circuit, which is connected to the basic unit of the electric meter and the communication module; the AC-DC conversion circuit converts the input power frequency AC power into DC power.

The energy storage unit includes an energy storage circuit, which is connected with the AC/DC circuit and the basic unit of the electric meter, and the energy storage circuit provides power for the entire electric energy meter when the switching power supply unit is powered off. Further, the energy storage unit also includes a switch control circuit, which is connected to the energy storage circuit and the communication module; the switch control circuit cuts off the discharge channel to the communication module, so that the remaining energy of the energy storage circuit is used to maintain the low energy meter. Power consumption operation delays the consumption of the clock battery by the electric energy meter. Furthermore, the basic unit of the electric meter includes a display unit, an electric energy measurement and a data processing unit. The display unit displays the information of the electric energy meter, including the measured and stored electric energy and status word; the electric energy measurement and data processing unit converts the input voltage and current into and The pulse signal whose power is in a certain proportional relationship is sent to the frequency divider and counter, and through the multiplier, current and voltage sampler, and A/D converter, the collection and transmission of related electrical parameters are realized. The energy storage unit includes a farad capacitor.

Due to the adoption of the above technical solution, the present invention has the following advantages: the battery failure rate in the electric meter is low, and the clock error of the electric meter is small; after the power is cut off, the electric meter can still perform active fault repair work. Other advantages, objectives and features of the present invention will be described in the following description to a certain extent, and to a certain extent, based on the following investigation and research, it will be obvious to those skilled in the art, or can be learned from It is taught in the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description and claims.
