Description

[0001] The present invention relates to the technical field of electric power equipment, and more particularly to a method, system, electronic device and storage medium for replacing an electric energy meter without power outage. Background Art

[0002] At present, traditional energy meter replacement operations usually require power outages, which include notifying users in advance, recording the base data, implementing power outages, removing old meters, installing new meters, verifying and restoring power supply, etc. This method not only affects the normal power consumption experience of users, but may also cause economic losses and even safety risks to large three-phase customers, industrial users who are not allowed to interrupt power supply, and users who ensure the supply of livelihood.

[0003] However, although the method of short-circuiting the energy meter to achieve non-stop meter replacement can solve the above problems to a certain extent, it also brings new challenges: it may cause the power company's electricity metering loss, and due to the lack of interaction with the power company's internal system, it is difficult to accurately count and trace the meter replacement data, which is not conducive to the power company's automated management and standardized operation. In addition, although some existing non-stop meter replacement devices have built-in metering modules, these modules are often not recognized by statutory metering agencies, resulting in the inability to guarantee the authenticity of the energy data during the meter replacement period. At the same time, these data cannot be directly uploaded to the power marketing field operation platform or the electricity consumption information collection system, which increases the cost of manual data processing and the risk of misoperation.

[0004] Therefore, developing a system and method to ensure continuous measurement and automatic collection of electric energy during the meter replacement process is an issue that needs to be urgently addressed by those skilled in the art. Summary of the invention

[0018] Optionally, it also includes operation process prompts and warnings, specifically: during the replacement process, process prompts are given in a multi-sensory manner according to the pre-stored operation process, and the operation process of the staff is monitored in real time and compared with the pre-stored operation process.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0036] On the one hand, an embodiment of the present invention discloses a method for replacing an electric energy meter without power outage, such as Figure 1 As shown, the specific steps are:

[0037] Step 1: Obtain a replacement instruction, and determine relevant data of the electric energy meter to be replaced and the new electric energy meter based on the replacement instruction;

[0038] Step 2: Replace the new electric energy meter to the original meter position of the electric energy meter to be replaced, and automatically read the electric energy data and meter number of the electric energy meter to be replaced and the new electric energy meter during the replacement process;

[0039] Step 3, based on the relevant data of the electric energy meter to be replaced, verify whether the meter number of the electric energy meter to be replaced is consistent; if consistent, calculate the continuous metering electric energy data during the replacement process based on the electric energy data of the electric energy meter to be replaced and the new electric energy meter, and encrypt and transmit and save the electric energy data, meter number and continuous metering electric energy data during the replacement process of the electric energy meter to be replaced and the new electric energy meter; if inconsistent, generate an alarm signal and stop the replacement.

[0040] In one embodiment, the relevant data of the electric energy meter to be replaced and the new electric energy meter include the meter number, specifications, and location of the electric energy meter to be replaced and the specifications of the new electric energy meter, etc.

[0041] Furthermore, first, the marketing system sends the smart meter replacement service work order to the marketing site mobile operation terminal, which receives the smart meter replacement service work order and verifies the information. The marketing site mobile operation terminal takes a photo of the connection of the incoming line module of the meter replacement device (also called the meter replacement instrument) to the joint junction box or puncture situation. Specifically:

[0042] Work order issuance: The backend of the marketing system will generate a smart meter replacement service work order based on needs (for example, updating of old electricity meters, changes in user needs, or system upgrades, etc.), and send the work order to the mobile operation terminal through the preset communication method.

[0043] Information verification: Verify relevant information on the mobile operation terminal to ensure that the upcoming operation is consistent with the work order requirements. This may include confirming the address, current meter information, new smart meter information, etc.

[0044] Photo record: In order to ensure the accuracy of the operation and subsequent review, the mobile operation terminal takes a photo of the incoming line module and the joint junction box or puncture point.

[0045] In one embodiment, the steps for acquiring the electric energy data of the electric energy meter to be replaced and the new electric energy meter are as follows:

[0046] The meter changing instrument is connected in parallel with the electric energy meter to be replaced, and the electric energy meter to be replaced is powered off and removed, and the meter number and electric energy data of the new electric energy meter installed in a meter changing position of the meter changing instrument are automatically read, that is, the first electric energy data;

[0047] Install the electric energy meter to be replaced to another meter replacement position of the meter replacement instrument, and automatically read the meter number and electric energy data of the electric energy meter to be replaced, that is, the second electric energy data;

[0048] Verify whether the meter number of the electric energy meter to be replaced is consistent based on the relevant data of the electric energy meter to be replaced. If it is consistent, cut off the power supply to remove the new electric energy meter, and read the electric energy reading of the new electric energy meter at the same time, that is, the third electric energy data;

[0049] Install the new electric energy meter to the original position of the electric energy meter to be replaced, turn on the power, read the electric energy data of the electric energy meter to be replaced, that is, the fourth electric energy data, and turn off the power of the electric energy meter to be replaced;

[0050] The electric energy data of the electric energy meter to be replaced is obtained according to the difference between the fourth electric energy data and the second electric energy data; and the electric energy data of the new electric energy meter is obtained according to the difference between the third electric energy data and the first electric energy data.

[0051] Furthermore, the mobile operation terminal at the marketing site sends user information through the established Bluetooth connection. The meter changer receives the user information, and the display screen reminds the operator to power on the new electric energy meter through text, voice and pictures. After the new electric energy meter is powered on, the meter changer reads the first electric energy data, that is, the electric energy data X1 and the meter number. At this time, the meter changer prompts to remove the electric energy meter to be replaced in the meter box and install it on another meter replacement position, that is, the meter replacement tray 2. After the electric energy meter to be replaced is powered on, the meter changer reads the second electric energy data, that is, the electric energy data J1 and the meter number. The meter changer automatically checks whether the number of the electric energy meter to be replaced issued is consistent with the number of the electric energy meter to be replaced. If not, it alarms and stops the meter replacement operation. If they are consistent, the third electric energy data of the new electric energy meter, that is, the electric energy data X2, is read through RS485 and the new electric energy meter is powered off, and the new electric energy meter is removed from the meter changer and installed on the meter position of the meter box. The electric energy meter to be replaced is powered off on the meter replacement instrument and the meter replacement instrument automatically reads the fourth electric energy data, i.e., the electric energy data J2. The mobile terminal at the marketing site takes a photo of the new electric energy meter having been installed to keep evidence.

[0052] At this point, the meter replacement process is complete, and the meter replacement instrument stores the continuously measured electric energy E during the operation:

[0053] E = (X2-X1) + (J2-J1);

[0054] The marketing site mobile operation terminal sends the command to read the continuous metering data and the indication of the new and old meters through the non-stop operation micro-application with the meter number of the energy meter to be replaced. The meter changer receives the command to read the data and uploads the new meter number + new meter data 2 + new meter data 1 + the meter number of the energy meter to be replaced + the energy meter data 2 + the energy meter data 1 + the energy meter number to be replaced + the energy meter data 2 to be replaced + the energy meter data 1 to be replaced + the energy data of this continuous metering + the number of meters replaced + the accumulated continuous metering energy according to the corresponding data of the meter number of the energy meter to be replaced. The marketing site mobile operation terminal automatically records the data uploaded by the meter changer. Scan the barcode of the new energy meter through the marketing site mobile operation terminal, restore the terminal and take a photo, seal the new energy meter and take a photo, and seal the meter box and take a photo. After the user confirms, submit the data to the marketing site operation platform.

[0055] Furthermore, the incoming line module of the meter replacement device is in the meter box to be replaced with the electric energy meter, so as to realize the parallel connection between the device and the electric energy meter to be replaced, and the new electric energy meter is installed on the device meter holder 1. At this time, the new electric energy meter and the electric energy meter to be replaced in the meter box are in a parallel relationship, and a wireless connection is established between the device and the mobile operation terminal at the marketing site through Bluetooth. The system for replacing the electric energy meter without power outage is completed through the above connection.

[0056] In one embodiment, the specific steps of encrypted transmission are:

[0057] Establish a communication connection between the mobile operation terminal at the marketing site and the meter changing instrument, and use an encryption algorithm to generate a shared key;

[0058] The meter changing instrument uses a shared key to encrypt sensitive data to be transmitted, and adds a digital signature to the encrypted data before transmitting it to the mobile operation terminal at the marketing site;

[0059] After receiving the encrypted data, the mobile operation terminal at the marketing site decrypts it, automatically records the data uploaded by the meter changer, and updates the shared key at the same time.

[0060] Furthermore, the marketing site mobile operation terminal and the meter changer establish a communication connection through a classic channel, use the national secret SM2 algorithm for key negotiation, and generate a pair of shared symmetric keys. This symmetric key is used as the key of the national secret SM4 symmetric encryption algorithm to encrypt sensitive data that needs to be transmitted (including the data and meter numbers of the new and old electricity meters, as well as continuous metering electricity data, etc.). At the same time, a digital signature based on the national secret SM3 hash algorithm is added to each transmitted data to ensure the authenticity of the data source and that it has not been tampered with. The encrypted data is transmitted from the meter changer to the marketing site mobile operation terminal. After the terminal receives the encrypted data, it uses the SM4 algorithm to decrypt it and automatically records the data uploaded by the meter changer. Whenever an electricity meter is replaced, the SM2 algorithm is immediately used to renegotiate and apply a new session key. At the same time, a state synchronization mechanism is introduced to ensure that the status between the marketing site mobile operation terminal and the meter changer is always consistent. When either party detects an abnormality, the other party can immediately take corresponding measures, such as suspending the operation or issuing an alarm.

[0061] In one embodiment, it also includes operation process prompts and warnings, specifically: during the replacement process, process prompts are given in a multi-sensory manner according to the pre-stored operation process, and the operation process of the staff is monitored in real time and compared with the pre-stored operation process. When the detection deviates from the pre-stored operation process, an error warning is automatically issued.

[0062] Another aspect of the present embodiment is a non-stop power replacement system for electric energy meters, which applies the above method, and includes a field operation mobile terminal and an electric energy meter replacement terminal, wherein the electric energy meter replacement terminal includes a processing module electrically connected to a first meter replacement position, a second meter replacement position, a storage module, and a human-computer interaction module, and an incoming line module electrically connected to the first meter replacement position and the second meter replacement position, respectively, and the incoming line module is electrically connected to a meter box;

[0063] The processing module obtains the electric energy data and meter number of the new electric energy meter through the first meter changing position, obtains the electric energy data and meter number of the electric energy meter to be replaced through the second meter changing position, calculates the continuous metering electric energy data based on the electric energy data of the new electric energy meter and the electric energy data of the electric energy meter to be replaced, and transmits the electric energy data and meter number of the new electric energy meter, the electric energy data and meter number of the electric energy meter to be replaced, and the continuous metering electric energy data to the storage module; and presents the pre-stored operation process in a multi-sensory manner in the human-computer interaction module; the power supply module supplies power to each module through the incoming line module.

[0064] In one embodiment, the incoming line module is connected to the meter box via the AC sampling module and the control switch module.

[0065] In one embodiment, a security module electrically connected to the processing module is further included to encrypt the electric energy data and meter number of the new electric energy meter, the electric energy data and meter number of the electric energy meter to be replaced, and the continuously measured electric energy data, and generate encrypted data for transmission.

[0066] In one embodiment, a communication module is further included, and the communication module is connected to the processing module and the field operation mobile terminal respectively, and is used to transmit the encrypted data to the field operation mobile terminal.

[0067] Furthermore, in the application scenario of the intelligent non-stop power meter replacement device, such as Figure 2 As shown, the scene includes the old electric energy meter to be replaced, the new electric energy meter, the mobile operation terminal of the power marketing site and the intelligent non-stop meter replacement device, that is, the meter replacement instrument. Among them, the meter replacement instrument reads the initial and final metered electricity of the old and new electric energy meters during the replacement operation process through RS485; through the communication module, this embodiment uses the Bluetooth module to communicate with the power marketing site operation terminal, and uploads the electric energy information of the meter replacement process to the marketing site operation platform; through the security module, the information and data of the meter replacement device and the power marketing site operation terminal are encrypted and decrypted; through the human-computer interaction module, reminders are given for the entire process of the meter replacement process, and the operation process is standardized; at the same time, the human-computer interaction module has text reminders and voice reminders for the meter replacement process operation, and also has picture and video image operation guidance; the storage module stores the operation data, and can graphically display the statistical operation electric energy data; and the human-computer interaction touch screen is used to query the statistical data; the AC sampling module collects data, and the processor determines that the current transformer CT is open and controls the internal protection circuit to avoid burning the device.

[0068] Furthermore, if Figure 3 As shown, 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 exchange position, i.e., an electric energy meter holder 1, a second meter exchange position, i.e., an electric energy meter holder 2, an incoming line module, an AC sampling module, a control switch, a power supply, etc.

[0069] Among them, the incoming line module includes but is not limited to a connecting wire harness, screws, punctures, etc. connected to the electric energy meter in the meter box, and is connected in parallel with the electric energy meter in the meter box.

[0070] The incoming line module connects the 10 wires of the three-phase four-wire energy meter or the 7 wires of the three-phase three-wire energy meter to the energy meter holder 1 and the energy meter holder 2 inside the device, and is connected to the power supply of the device through the control switch.

[0071] The control switch is responsible for turning off and on the power supply of the entire device.

[0072] The power supply converts high voltage 380V AC into low voltage DC to power the overall circuit of the device.

[0073] RS485-1 and RS485-2 are connected to the terminals of the electric energy meter support 1 and the electric energy meter support 2 respectively, and the terminals are connected to the RS485 interfaces of the new and old electric energy meters respectively.

[0074] The energy meter holder 1 and the energy meter holder 2 respectively contain 10 wires of a three-phase four-wire energy meter, and are compatible with the terminal blocks for 7 wires of a three-phase three-wire energy meter. The terminal blocks of the holder 1 and the holder 2 are respectively connected to the three-phase voltage and current terminal blocks of the new and old energy meters.

[0075] The processor uses ARM or a single-chip microcomputer, which is responsible for the overall collection, control and logical judgment of the device. The processor collects the initial and final electricity meter data of the electricity meter to be replaced and the new electricity meter during the meter replacement process through RS485-1 and RS485-2. The processor calculates the difference between the initial and final electricity data of the electricity meter to be replaced as J, and the difference between the initial and final electricity data of the new electricity meter as X. The sum of the data of J and X is the electricity LQ measured during the meter replacement process. The electricity LQ at this time and the current date and time are saved in the storage module, which can be statistically queried and traced later within the power company. The processor communicates with the marketing site mobile operation terminal through the Bluetooth module, realizes authentication and data encryption and decryption through the security module, and uploads the initial and final electricity and electricity LQ of the old and new meters to the marketing site operation platform. The marketing site operation platform can transmit the data to the electricity information collection system. The security module contains encryption and decryption algorithms, which are not limited to software-implemented algorithms and hardware-implemented algorithms.

[0076] The human-computer interaction module adopts a touch screen design, which interacts with the processor to display the power of the new energy meter to be replaced in real time during the operation. The human-computer interaction module contains a voice processing module, an image and video processing module, and a text processing module. During the human-computer interaction process, the operation process is strictly planned and prompted, and the prompts of listening to voice prompts, reading text prompts, and viewing pictures and image and video prompts are realized, realizing static and dynamic, multi-sensory all-round perception to ensure the safety of the operation process. The touch screen of the human-computer interaction module can be used to query stored data and watch the operation process guidance.
