Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically to an uninterrupted meter replacement device. Background Technology

[0002] Currently, traditional electricity meter replacement work must be carried out during a power outage. This process involves a series of steps, including posting power outage notices in advance, recording meter readings and informing users, implementing the power outage, removing the old meter, installing the new meter, verifying the accuracy of the new meter, and restoring power. While this method ensures the safety of the replacement work, it inevitably affects users' normal electricity usage. This is especially true for large customers using three-phase electricity, industrial users who cannot tolerate power outages, and users whose livelihoods are guaranteed. For them, replacing meters during a power outage can lead to economic losses and, in extreme cases, even endanger lives.

[0003] However, while the method of short-circuiting the electricity meter to achieve uninterrupted meter replacement avoids the above problems, it introduces new challenges: this method may cause the power company to suffer losses in metered electricity fees, and due to the lack of operational procedures and standardization, there are certain safety hazards, and the safety of operation and the accuracy of data cannot be fully guaranteed.

[0004] Therefore, how to achieve a system that can complete continuous metering during the replacement of electricity meters without affecting users' normal production and life, and can also standardize the operation process, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a meter replacement device that does not require power outage, thus overcoming the above-mentioned defects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A non-disconnect meter replacement device includes a field operation mobile terminal and a meter replacement terminal. The meter replacement terminal includes a processing module electrically connected to a first replacement position, a second replacement position, a storage module, and a human-machine interaction module, and an incoming line module electrically connected to the first replacement position and the second replacement position, respectively. The storage module and the processing module are both encapsulated in a housing. The first replacement position, the second replacement position, and the incoming line module are all fixed to the housing. The human-machine interaction module is disposed on the surface of the housing.

[0008] Optionally, the incoming line module is connected to the metering box via a control switch module.

[0009] Optionally, an AC sampling module is further provided between the incoming line module and the control switch module.

[0010] Optionally, it may also include a security module electrically connected to the processing module.

[0011] Optionally, it also includes a communication module, which is connected to the processing module and the on-site operation mobile terminal respectively, and is used for information transmission between the processing module and the on-site operation mobile terminal.

[0012] Optionally, the human-computer interaction module includes a voice prompt unit, a text prompt unit, and a video guidance unit, all of which are electrically connected to the processing module.

[0013] Optionally, the human-computer interaction module is a touch-screen display.

[0014] Optionally, the on-site mobile terminal further includes an alarm module, which is electrically connected to the processing module.

[0015] As can be seen from the above technical solution, this utility model discloses a meter replacement device that does not require power outages, which has the following advantages compared with the prior art:

[0016] 1. By providing guidance and reminders on the meter replacement process through text, voice, images, or videos, the process has been fully standardized. This not only improves the accuracy of operators' work but also greatly reduces misoperations caused by human negligence or misunderstanding, thereby enhancing work safety.

[0017] 2. During the replacement of electricity meters, the system automatically reads the electricity consumption data of the old and new meters and uses this legally valid data as the metered electricity consumption during the replacement process. This ensures the accuracy and legal validity of the data, avoids possible human error, and provides reliable evidence to support any disputes that may arise later.

[0018] 3. The ability to upload electricity data from both new and old meters in real time not only facilitates the power company's internal statistical query of electricity consumption during meter replacement operations, but also promotes data transparency and traceability.

[0019] 4. Standardized meter replacement procedures and safety instructions effectively ensured the safety of operators, reduced operational risks, met the requirements for safe power production, and further promoted the healthy development of the power industry. Attached Figure Description

[0032] Furthermore, in application scenarios of intelligent uninterrupted power meter replacement devices, such as Figure 1 As shown, the scenario includes the electricity meter to be replaced, the new electricity meter, and a mobile terminal for on-site operations, namely the mobile terminal for power marketing and the electricity meter replacement device, i.e., the intelligent uninterrupted power meter replacement device. The intelligent uninterrupted power meter replacement device reads the initial and final metered electricity consumption during the replacement process via RS485; it communicates with the mobile terminal for power marketing via a communication module (Bluetooth module) and uploads the electricity information during the replacement process to the marketing on-site operation platform; a security module handles the encryption and decryption of information and data between the replacement device and the mobile terminal for power marketing; a human-machine interaction module provides reminders throughout the replacement process and standardizes the operation procedures; the human-machine interaction module also provides text and voice prompts for the replacement process, as well as image and video guidance; a storage module stores the operation data and can graphically display statistical data; statistical data can be queried via the human-machine interaction module; and an AC sampling module collects data, and a processing module determines if the current transformer (CT) is open and controls the internal protection circuit to prevent damage to the device.

[0033] Furthermore, such as Figure 2 As shown, the specific structure will be further explained. In this embodiment, the system includes a processing module, i.e., a processor, a human-computer interaction module, a communication module, i.e., a Bluetooth module, a security module, a storage module, RS485-1, RS485-2, a first meter changing position, i.e., an energy meter holder 1, a second meter changing position, i.e., an energy meter holder 2, an incoming line module, an AC sampling module, a control switch module, i.e., a switch, a power supply, etc.

[0034] The security module can use a security chip such as TF32A9FAL1, which supports symmetric cryptography algorithms (such as SM4), asymmetric cryptography algorithms (such as SM2), and hash algorithms (such as SM3) specified by the State Cryptography Administration. The security module has power supply, storage, and data input and output interfaces.

[0035] The incoming line module includes, but is not limited to, the connecting harness, screws, piercings, etc., for connecting the energy meters in the metering box, and is connected in parallel with the energy meters in the metering box.

[0036] The incoming line module connects the 10 wires of a three-phase four-wire energy meter or the 7 wires of a three-phase three-wire energy meter to the energy meter bracket 1 and energy meter bracket 2 inside the device, and is also connected to the device power supply through a switch.

[0037] The switch is responsible for turning the power supply to the entire device on and off.

It collects initial and final electricity consumption data from both the old and new meters during the meter replacement process via RS485-1 and RS485-2. The processor calculates the difference between the initial and final electricity consumption data of the old meter as J, and the difference as X. The sum of J and X is the electricity consumption LQ measured during the meter replacement process. This LQ, along with the current date and time, is stored in the storage module for later statistical querying and traceability by the power company. The processor communicates with the mobile operation terminal at the marketing site via Bluetooth, and uses a security module for authentication and data encryption / decryption. It then uploads the initial and final electricity consumption data of the old and new meters, as well as the electricity consumption LQ, to the marketing site operation platform, which can then transmit the data to the electricity consumption information collection system.

[0042] The human-machine interface (HMI) module features a touchscreen design, interacting with the processor to display the real-time battery levels of both old and new meters during the operation. The HMI module includes voice processing, image / video processing, and text processing modules.
