Description

Technical Field

[0001] This invention relates to the field of power metering technology, specifically a plug-and-play residential energy consumption analysis device. Background Technology

[0002] In recent years, public concerns about the accuracy of metering in various fields have frequently become social hotspots, placing higher demands on companies to strengthen the verification of electricity metering accuracy and improve customer service levels. Currently, the accuracy of electricity metering is mainly verified through electricity meter calibration devices. However, the calibration process and results are relatively professional and obscure, and can only verify the overall accuracy of the electricity meter. It is difficult to provide effective answers to the specific reasons for the increase in electricity consumption that the public is concerned about, making it difficult for the general public to accept. There is an urgent need for a flexible, intuitive, and accurate new metering accuracy verification solution.

[0003] Therefore, developing a flexible access-type auxiliary verification device for metering accuracy, and developing plug-and-play, metering analysis, and carrier communication functions on the customer side, combined with electricity meter data, to achieve electricity comparison analysis and accuracy verification has become an urgent problem to be solved. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a plug-and-play residential energy consumption analysis device. It develops plug-and-play, metering analysis and carrier communication functions on the customer side, and combines electricity meter data to realize electricity comparison analysis and accuracy verification.

[0005] The technical solution adopted by this invention to solve its technical problem is: A plug-and-play residential energy analysis device includes a power strip body, a detachable housing mounted on the power strip body, and a lifting plate mounted inside the housing and moving up and down within the housing. The power strip's sockets are mounted on the lifting plate, and the lower ends of the sockets on the lifting plate are symmetrically provided with first metal plates. The first metal plates are provided with positioning mechanisms for positioning the plugs. The bottom of the power strip body is provided with a second metal plate that extends between the two first metal plates. The power strip body also includes a dual-frequency transceiver and a memory. The positioning mechanism includes a fixed shell disposed on the outside of the first metal sheet, a groove disposed in the first metal sheet, and a positioning ball disposed in the groove. The inner walls of the upper and lower sides of the groove are both arc-shaped surfaces. The side of the plug is provided with a slot that cooperates with the positioning ball. The fixed shell is provided with a first compression spring that pushes the positioning ball to move toward the plug.

[0006] Furthermore, the dual-frequency transceiver is selected as the CC1310 dual-frequency transceiver.

[0007] Furthermore, the communication between the socket and the electricity meter adopts a 50-channel frequency hopping meter.

[0008] Furthermore, the memory is selected as 64 kB FRAM.

[0009] Furthermore, the housing and the power strip body are connected by screws.

[0010] Furthermore, a guide rod is provided inside the housing, the upper end of the guide rod passes through the lifting plate and is slidably connected to the lifting plate, and a second compression spring is provided on the guide rod to push the lifting plate upward.

[0011] Furthermore, the upper end of the inner wall of the housing is provided with a positioning protrusion, and the outer edge of the upper end of the lifting plate is provided with a positioning groove that cooperates with the positioning protrusion.

[0012] Furthermore, the bottom of the first metal sheet is provided with an arc-shaped metal sheet.

[0013] Furthermore, the upper end of the power strip body is provided with a cover plate.

[0014] The beneficial effects of this invention are: 1. This invention includes a detachable housing mounted on the power strip body, a lifting plate mounted inside the housing and moving up and down within the housing, the sockets of the power strip being mounted on the lifting plate, and first metal plates symmetrically positioned at the lower end of the sockets on the lifting plate. The first metal plates are equipped with a positioning mechanism for positioning the plug. A second metal plate is located at the bottom of the power strip body, extending between the two first metal plates. The power strip body also contains a dual-frequency transceiver and a memory. After being plugged in, the built-in dual-frequency transceiver automatically forms a star network within 200 ms, using the electricity meter as the sole root node. Without any distribution network interaction, it can read the total meter reading in real time and locally break down the energy consumption of each branch circuit. Combined with the electricity meter data, it achieves energy comparison analysis and accuracy verification, and provides convenient and intuitive energy consumption reports and energy-saving suggestions, effectively answering customers' questions about the "last mile" of electricity metering accuracy.

[0015] 2. The positioning mechanism in this invention includes a fixed shell disposed on the outside of the first metal sheet, a groove disposed within the first metal sheet, and a positioning ball disposed within the groove. The inner walls of the upper and lower sides of the groove are both arc-shaped surfaces. The side of the plug has a slot that mates with the positioning ball. The fixed shell contains a first compression spring that pushes the positioning ball toward the plug. After the plug is inserted into the socket, under the action of the first compression spring, the positioning ball engages with the slot, increasing the friction of the plug and preventing it from loosening and falling off. When it is necessary to unplug the plug, the lifting plate is pressed down, and the positioning ball separates from the slot, making it easy to unplug the plug.

[0016] 3. In this invention, the housing and the power strip body are connected by screws. The sockets and the first metal plate are modularly designed, so if a socket is damaged, it is easy to replace; only the module needs to be replaced, without replacing the entire power strip.

[0017] 4. The present invention has a cover plate on the upper end of the power strip body. One side of the cover plate is hinged to the power strip body, and the other side of the cover plate is connected to the power strip body by a latch, thereby realizing the dustproof function.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0022] like Figure 2 and Figure 3As shown, a plug-and-play residential energy consumption analysis device includes a power strip body 1, a detachable housing 2 mounted on the power strip body 1, and a lifting plate 3 mounted inside the housing 2 and moving up and down within the housing. The power strip's sockets are located on the lifting plate 3. Symmetrically positioned at the lower end of each socket on the lifting plate 3 are first metal plates 4, each with a positioning mechanism for positioning the plug. A second metal plate 5, extending between the two first metal plates 4, is located at the bottom of the power strip body 1. The second metal plate 5 is connected to an external power supply. The power strip body 1 also contains a dual-frequency transceiver 6 and a memory 7. After plugging in, the built-in dual-frequency transceiver 6 automatically forms a star network within 200 ms, using the energy meter as the sole root node. Without any distribution network interaction, it can read the total meter reading in real time and locally break down the energy consumption of each branch circuit. Combined with the energy meter data, it achieves energy comparison analysis and accuracy verification, and provides convenient and intuitive energy consumption reports and energy-saving suggestions, effectively answering customers' questions about the "last mile" of energy meter accuracy.

[0023] like Figure 3 and Figure 4 As shown, the positioning mechanism includes a fixed shell 8 disposed on the outside of the first metal sheet 4, a groove 9 disposed within the first metal sheet 4, and a positioning ball 10 disposed within the groove 9. The inner walls of the upper and lower sides of the groove 9 are both arc-shaped surfaces, allowing the positioning ball 10 to move left and right within the groove without falling out. A slot 11 is provided on the side of the plug to engage with the positioning ball 10. A first compression spring 12 is provided inside the fixed shell 8 to push the positioning ball 10 towards the plug. After the plug is inserted into the socket, under the action of the first compression spring 12, the positioning ball 10 engages with the slot 11, increasing the friction of the plug and preventing it from loosening and falling out. When it is necessary to unplug the plug, pressing down on the lifting plate 3 separates the positioning ball 10 from the slot 11, making it easy to unplug the plug.

[0024] The dual-frequency transceiver 6 uses the CC1310 dual-frequency transceiver. After power-on, it automatically forms a star network within 200 ms with the energy meter as the sole root node. Without any distribution network interaction, it can read the total meter power consumption in real time and locally split the energy consumption of each branch.

[0025] A 50-channel frequency hopping table is used between the socket and the electricity meter. The key is automatically updated every 100 frames transmitted to prevent interference from neighboring channels and leakage of electricity data, ensuring secure plug-and-play communication. The "50-channel frequency hopping table" does not refer to a "50 Hz power frequency," but rather to the pre-defined 50 mutually orthogonal and non-overlapping narrowband channels (e.g., 433.075 MHz, 433.125 MHz… 433.325 MHz, with a 50 kHz interval between each channel) within the Sub-1 GHz band. The socket and the electricity meter create a "frequency hopping table" using these 50 frequencies in a pre-defined order. During communication, both parties hop to the next frequency point according to the table after each frame (or every 100 ms), and the 50 frequencies are used cyclically. Advantages: Resistance to co-channel interference – If a neighbor also uses a 433 MHz product, it will only collide with one frequency point, and the next frame will skip it; Resistance to narrowband blocking – If a frequency point is occupied by a walkie-talkie or garage door remote control for a long time, the system will lose at most 1 / 50 of the frames, and the rest of the frames will be delivered normally; Security – Eavesdroppers do not know the frequency hopping sequence and cannot continuously listen, naturally increasing the difficulty of cracking.

[0026] The memory 7 uses 64 kB FRAM. When the wireless link is lost, it caches the power consumption pulse sequence in real time. After the link is restored, it is uploaded in batches according to the timestamp, ensuring that the household power consumption statistics are complete and achieving "continued recording even when power is lost". "64 kB FRAM" refers to a 64-kilobyte "ferroelectric random access memory" integrated inside the socket. It can be randomly read and written like SRAM and is not lost when power is lost like EEPROM / Flash, but it is faster, consumes less power, and has almost unlimited erase and write cycles. Its role in the "residential energy consumption analysis socket" is to cache each power consumption pulse (with 4-byte timestamp) in real time. When the wireless network is lost, it writes to the FRAM first and then uploads the whole packet after the network is restored, ensuring "continued recording even when power is lost". No additional backup battery is needed - FRAM retains data for more than 10 years when power is lost, making it suitable for "plug and play" scenarios. The erase and write life is much longer than Flash, and it can withstand one pulse per second and continuous writing for 30 years without damage.

[0027] like Figure 2 As shown, the housing 2 is connected to the power strip body 1 by screws 13. The sockets and the first metal plate are modularly arranged, so if a socket is damaged, it is easy to replace. Only one module needs to be replaced, and the entire power strip does not need to be replaced.

[0028] like Figure 3As shown, a guide rod 14 is provided inside the housing 2. The upper end of the guide rod 14 passes through the lifting plate 3 and is slidably connected to the lifting plate 3. A second compression spring 15 is provided on the guide rod 14 to push the lifting plate 3 upward. A mounting plate is provided inside the housing 2. The lower end of the guide rod 14 is fixed to the mounting plate. The lower end of the second compression spring 15 contacts the mounting plate, and the upper end of the second compression spring 15 contacts the lifting plate 3. When the lifting plate 3 is pressed, the lifting plate 3 moves downward against the elastic force of the second compression spring 15, and the positioning ball 10 separates from the slot 11. After the plug is unplugged, the lifting plate 3 moves upward and resets under the action of the second compression spring 15.

[0029] like Figure 3 As shown, the upper end of the inner wall of the housing 2 is provided with a positioning protrusion 18, and the outer edge of the upper end of the lifting plate 3 is provided with a positioning groove 19 that cooperates with the positioning protrusion 18. The positioning protrusion 18 and the positioning groove 19 cooperate to realize the positioning of the lifting plate 3 and prevent the lifting plate 3 from falling off the housing 2.

[0030] like Figure 3 As shown, the bottom of the first metal sheet 4 is provided with an arc-shaped metal sheet 16, which is closely attached to the second metal sheet 5 to prevent circuit interruption.

[0031] like Figure 1 As shown, the upper end of the power strip body 1 is provided with a cover plate 17. One side of the cover plate 17 is hinged to the power strip body 1, and the other side of the cover plate is connected to the power strip body 1 by a latch, thereby realizing the function of dust prevention.
