Technical Field

[0001] The utility model relates to the technical field of electric energy meters, in particular to a multi-user intelligent electric energy meter. Background Art

[0002] With technological advancements and social development, energy management is becoming increasingly important. In the power sector, in particular, accurate and reliable energy metering is crucial to the operations of power companies. Traditional energy meters, with their complex structure and limited functionality, are unable to meet the diverse metering requirements of modern power systems. Furthermore, the rise of the Internet of Things (IoT) is placing higher demands on energy meters, such as remote data transmission and real-time monitoring.

[0003] Most current electricity meters on the market utilize discrete components, with the metering module, power module, and storage module all installed separately. This significantly increases the meter's overall size, resulting in relatively high manufacturing costs and inconvenience in maintenance and upgrades. Furthermore, these meters often lack effective communication capabilities, making them difficult to meet the power company's needs for real-time monitoring of electricity usage data.

[0004] In order to overcome the above shortcomings, the present invention proposes a new multi-user smart energy meter. Utility Model Content

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0028] The utility model provides a multi-user intelligent electric energy meter.

[0029] In this embodiment, referring to Figure 1-5 The multi-user smart energy meter includes a bottom shell 1 and an upper cover 2 covering the bottom shell 1. The openings 14 at both ends of the bottom shell 1 are provided with an incoming line base 3 and an outgoing line base 4. The outgoing line base 4 is provided with an outgoing line terminal 5. A connecting boss 6 is provided in the bottom shell 1, and an intelligent processing chip 7 is fixed on the connecting boss 6. The intelligent processing chip 7 is provided with a metering module, a power module, a storage module, a 485 communication module and a liquid crystal display 8. A transparent window 9 is provided on the upper cover 2 above the liquid crystal display. The incoming line base and the outgoing line terminal are electrically connected to the metering module.

[0030] The above technical solution integrates multiple functional modules (metering module, power module, storage module, 485 communication module) into a single intelligent processing chip, combined with a compact design, to achieve miniaturization of the electricity meter. This not only saves installation space but also reduces manufacturing costs. Furthermore, the transparent window allows direct viewing of the LCD display, enhancing the user experience.

[0031] Specifically, the liquid crystal display screen 8 is connected to a backlight screen 11 via a connecting rod 10 , and the backlight screen 11 is connected to the intelligent processing chip via a fixing column 12 .

[0032] In this embodiment, a backlight screen is added and connected to the intelligent processing chip via a fixing post, ensuring that the information on the LCD screen can be clearly read even in low light conditions. The introduction of the backlight screen improves the usability of the energy meter in various environments, especially at night or in dimly lit places.

[0033] Specifically, a flip cover 15 for covering the opening is rotatably connected to the rotating shafts 13 at both ends of the upper cover 2.

[0034] In this embodiment, rotatably connected flip covers are provided at both ends of the upper cover to effectively protect the wiring terminals on the incoming and outgoing wiring bases from external environmental influences, preventing the ingress of contaminants such as dust and moisture, thereby extending the service life of the energy meter. Furthermore, the flip cover design also facilitates daily wiring operations.

[0035] Specifically, lead sealing posts 16 are provided on the four corners of the bottom shell, and lead sealing holes 17 are provided on the tops of the lead sealing posts 16. The flip cover is provided with through holes 18 for the lead sealing posts to pass through.

[0036] In this embodiment, the seal post on the bottom shell and the through hole on the flip cover work together to provide an effective anti-tampering mechanism. The seal can prevent unauthorized personnel from opening the meter to a certain extent, ensuring the security and accuracy of the meter data.

[0037] Specifically, a wiring copper plate 20 is fixed in the wiring slot 19 of the incoming line base by a wiring bolt 22. A through slot 21 is provided on the back of the wiring slot for the wiring copper plate 20 to pass through. A plurality of wiring holes 23 are provided at intervals on one end of the wiring copper plate 20 away from the wiring bolt 22.

[0038] In this embodiment, conventional energy meters are designed primarily for low-current applications in household environments. The connection ports at both ends can typically only carry relatively small currents. To accurately measure energy in high-current environments, a current transformer is typically required at the front end of the meter. However, the present invention utilizes a copper wiring plate at the incoming line, allowing the meter to be directly connected to high-current lines. This eliminates the need for a transformer, simplifies the system structure, and improves the practicality and cost-effectiveness of the meter.

[0039] The copper wiring plate can carry larger cables. The thickness of the copper wiring plate is between 3.5-5mm and can handle large currents of 350-600AD. This eliminates the need for a transformer for the energy meter.

[0040] Specifically, connecting screw holes 24 are provided on both sides of the wiring slot 19 , and studs 25 are threadedly connected to the connecting screw holes 24 . Positioning screw holes 26 threadedly connected to the studs 25 are provided on both sides of the wiring copper plate.

[0041] In this embodiment, by setting connecting screw holes on both sides of the wiring slot and using studs to connect with the positioning screw holes on the wiring copper plate, this structural design ensures that the wiring copper plate is firmly fixed in the wiring slot, thereby enhancing the stability and reliability of the connection.

[0042] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
