Description
Monitor electricity meters Technical Field
[0001] This application relates to the field of power measurement technology, and in particular to a monitoring energy meter. Background Technology
[0002] The efficient use of electricity has become a focus of attention across various industries. Real-time monitoring of electricity usage can identify peak energy consumption and abnormal electricity consumption behavior, optimize energy allocation, improve equipment operating efficiency, and reduce operating costs. Furthermore, electricity monitoring can promptly detect potential faults in the power system, prevent power accidents, and ensure the reliability and security of power supply. Therefore, electricity monitoring is not only an important means of energy conservation and emission reduction but also a key measure to ensure the stable operation of the power system.
[0003] In existing technologies, electricity meters and monitoring relays are used to measure electrical energy and monitor signals in the power grid. Electricity meters are used for measuring and metering electrical energy; however, they cannot comprehensively monitor power grid signals, such as voltage and current fluctuations and phase imbalances, and lack alarm and fault handling capabilities for abnormal situations. Monitoring relays, on the other hand, focus on monitoring and protecting power grid signals. They can detect abnormal changes in voltage and current signals in the power grid in real time and issue alarms or take protective measures when necessary, but they do not have electricity metering capabilities. Therefore, within the existing technological framework, it is usually necessary to use both electricity meters and monitoring relays simultaneously to achieve comprehensive power grid signal monitoring and management.
[0004] However, the current technology that uses both electricity meters and monitoring relays simultaneously suffers from high costs. The cost of these two devices is high, especially in large-scale applications, where it can increase exponentially.

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0038] The technical solutions of this application will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.
[0039] To clearly understand the technical solution of this application, the existing technology solutions will first be described in detail. In the prior art, the metering of electrical energy and the monitoring of power grid signals typically rely on the combined use of an electricity meter and a monitoring relay. The electricity meter is mainly responsible for the measurement and metering of electrical energy, but it lacks the ability to alarm abnormalities and handle faults. On the other hand, the monitoring relay focuses on monitoring and protecting power grid signals, and can detect abnormal changes in signals such as voltage and current in the power grid in real time, and issue alarms or take protective measures when necessary, but it does not have the function of electricity metering. Therefore, in order to achieve comprehensive electricity metering and power grid signal monitoring, it is usually necessary to use both electricity meters and monitoring relays simultaneously.
[0040] However, the simultaneous use of electricity meters and monitoring relays in existing technologies leads to high costs. Both devices are inherently expensive, especially in large-scale applications, where the overall cost increases significantly. Furthermore, compatibility issues between these two devices often necessitate additional interfaces for effective communication and collaboration, further increasing system complexity and cost.
[0041] Therefore, addressing the high cost associated with using both electricity meters and monitoring relays in existing technologies, this research found that a multi-functional device integrating electricity metering and grid signal monitoring can be developed to reduce the number of devices and related interface requirements: ① Develop an intelligent power management system that integrates electricity metering and grid signal monitoring functions into a single device, utilizing advanced sensors and processing technologies to achieve multi-functional operation. ② Design modular devices that allow users to select and combine electricity metering and monitoring modules as needed, enabling flexible functional configuration and cost control. ③ Integrate wired or wireless communication modules into the device to achieve remote monitoring and control, reducing the need for physical interfaces and lowering installation and maintenance costs.
[0042] Specifically, a multi-functional device integrating electricity metering and grid signal monitoring can be developed. This device integrates multiple functional components, including an input interface for receiving multi-phase power signals and neutral line signals, a power supply connection for powering the device, and a processing unit responsible for collecting and analyzing current and voltage data to calculate power parameters. When power parameters exceed preset safety ranges, the processing unit generates corresponding alarm and control signals. Furthermore, the device also has an output interface for transmitting alarm and control signals, as well as power signals. By integrating these functions into a single device, costs are effectively reduced.
[0043] The monitoring energy meter of this application integrates energy metering and grid signal monitoring functions into a single device, solving the problem of requiring the simultaneous use of an energy meter and a monitoring relay in the prior art. This monitoring energy meter can collect and process voltage and current signals from the three-phase input signals, enabling energy metering and grid signal monitoring, and generating control and alarm signals when an anomaly is detected. This integrated design reduces the overall cost of the device.
[0044] Based on the above-mentioned inventive discovery, the technical solution of this application is proposed.

The first power supply module 203 is connected to multiple first input terminals 101. The multiple first input terminals 101 are used to input external three-phase input signals and supply power to the first power supply module 203. The first signal acquisition module 201 is used to acquire the first voltage signal and the first electrical signal of the three-phase input signals. The first signal acquisition module 201 sends a first voltage signal and a first current signal to a first signal management and control module 202, and sends the three-phase input signal to multiple first output terminals 102. The first signal management and control module 202 is used to perform calculations and monitoring based on the first voltage signal and the first current signal, and generate a first power signal, a first control signal and a first alarm signal. The first control signal is sent to multiple second output terminals 103, and the first power signal and the first alarm signal are sent to multiple third output terminals 104. The first power supply module 203 is used to supply power to the first signal acquisition module 201 and the first signal management and control module 202.
[0053] Specifically, the connections between the modules and ports can be achieved through electrical wiring on the first circuit board 200. These connections ensure the normal operation of the signal acquisition and processing functions of the monitoring energy meter, ultimately realizing the energy metering and grid signal monitoring functions of the monitoring energy meter.
[0054] This embodiment provides a monitoring energy meter that integrates energy metering and grid signal monitoring functions into a single device, solving the high cost problem in existing technologies.

[0066] Multiple second input terminals 105 are connected to the first signal acquisition module 201; wherein, the multiple second input terminals 105 are used to input external neutral line signals.
[0067] Specifically, the connection between the multiple second input terminals 105 and the first signal acquisition module 201 can be achieved through electrical connections, such as wires, conductive paths on a printed circuit board, or other suitable electrical connection methods. This design allows the externally input neutral line signal to be transmitted to the first signal acquisition module 201, enabling the module to use these signals for accurate energy metering, thereby improving the overall performance of the energy meter.
