Abstract
Description
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. Furthermore, compatibility issues between these two devices may require additional interfaces, further increasing costs. Utility Model Content

[0091] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is presented in connection with the drawings, wherein the same numbers on different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not meant to be all inclusive of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0092] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.
[0093] In order to clearly understand the technical solutions of the present application, the prior art solutions will be described in detail first. In the prior art, the measurement of electric energy and the monitoring of power grid signals usually rely on the combined use of electric energy meters and monitoring relays. The electric energy meter is mainly responsible for the measurement and metering of electric energy, but it lacks the ability of abnormal alarm and fault handling. On the other hand, the monitoring relay focuses on monitoring and protecting power grid signals, which can detect abnormal changes of signals such as voltage and current in the power grid in real time, and issue an alarm or take protective measures when necessary, but it does not have the function of electric energy metering. Therefore, in order to achieve comprehensive electric energy metering and power grid signal monitoring, it is usually necessary to use both electric energy meters and monitoring relays.
[0094] However, the simultaneous use of electric energy meters and monitoring relays in the prior art brings the problem of high cost. The prices of these two devices are relatively high, especially in large-scale application scenarios, the overall cost will increase significantly. In addition, due to the compatibility problem of these two devices, additional interfaces are usually needed to realize effective communication and cooperation between them, which further increases the complexity and cost of the system.
[0095] Therefore, in order to solve the problem of high cost caused by the simultaneous use of electric energy meters and monitoring relays in the prior art, it is found in the research that in order to solve this problem, a multifunctional device integrating electric energy metering and power grid signal monitoring functions can be developed, thereby reducing the number of devices and the demand for related interfaces: ① Develop an intelligent electric quantity management system, integrate electric energy metering and power grid signal monitoring functions into a single device, and use advanced sensors and processing technology to realize multifunctional operation. ② Design modular devices, allowing users to select and combine electric energy metering and monitoring modules as needed to achieve flexible function configuration and cost control. ③ Integrate wired or wireless communication modules in the device to realize remote monitoring and control, reduce the demand for physical interfaces and reduce installation and maintenance costs.
[0096] Specifically, a multifunctional device integrating power metering and grid signal monitoring functions can be developed. The device integrates multiple functional components, including input interfaces for receiving multi-phase power signals and neutral line signals, power connections for powering the device, and a processing unit responsible for collecting and analyzing current and voltage data to calculate power parameters. When the power parameters exceed the preset safety range, the processing unit generates corresponding alarm and control signals. In addition, the device is also provided with output interfaces for transmitting alarm and control signals, as well as power signals. By integrating these functions into one device, the cost is effectively reduced.
[0097] The monitoring power meter of the embodiments of the present application solves the problem of needing to use both a power meter and a monitoring relay in the prior art by integrating power metering and grid signal monitoring functions into one device. The monitoring power meter can collect and process voltage signals and current signals of three-phase input signals, realize power metering and grid signal monitoring, and generate control signals and alarm signals when detecting abnormalities. This integrated design reduces the overall cost of the device.
[0098] Based on the above creative findings, the technical solutions of the present application are proposed.
[0099] The embodiments of the present application will be introduced below in conjunction with the accompanying drawings of the specification.

[0107] Specifically, the connection between each module and port can be realized by electrical wiring on the first circuit board 200. These connections ensure the normal operation of the signal acquisition and processing functions of the monitoring electric energy meter, and ultimately realize the functions of electric energy metering and power grid signal monitoring of the monitoring electric energy meter.
[0108] The monitoring electric energy meter provided by the embodiment solves the problem of high cost in the prior art by integrating the electric energy metering function and the power grid signal monitoring function into one device.

[0110] Specifically, the panel assembly 300 is a structural part of the monitoring electric energy meter, used for mounting and supporting the display screen 301, the plurality of control keys 302, and the indicator light 303. The display screen 301 is a visual interface used for displaying configuration information of the electric energy meter.

The indicator light 303 is a state indicating device used for providing visual warning when a fault occurs in the three-phase input signal, prompting the user to pay attention by displaying a state change.
[0111] The circuit board 200 further includes a display module 206, which is connected to the display screen 301, the plurality of control keys 302, the indicator light 303, the first signal management control module 202, and the first power module 203.
