Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meters, and in particular to an RFID key management method and system for an operating electric energy metering device. Background Art

[0002] According to the Measurement Law and technical standards, electric energy metering devices should be installed at the property boundary, that is, the boundary of the customer's and the power supply company's respective assets. From this perspective, electric energy metering devices are naturally close to customers. On the other hand, as the direct basis for electricity transactions between suppliers and users, electric energy metering devices only allow authorized personnel to perform operations and tests within a limited range. When unauthorized personnel operate, it is usually considered that the corresponding electric energy metering device has a high risk of electricity theft or breach of contract. It can be seen that the implementation of key and authorization management for on-site metering devices is of great significance to maintaining accurate and reliable measurement, supporting fair and just transactions, and protecting the legitimate rights and interests of both suppliers and users.

[0003] At present, the technical measures of applying seals are usually adopted for the protection of metering devices in field operation, that is, a closable cover or box is installed on the operating part of the metering device, and a special seal is installed at the switch. Once the seal is disassembled, it cannot be reused. However, the structure of the seal itself is relatively simple and lacks the necessary anti-counterfeiting measures. In recent years, the unauthorized operation of metering devices and the resulting hidden dangers of electricity theft / violation of electricity use and safety hazards have shown an upward trend. Traditional seals are difficult to fundamentally prohibit illegal operations and lack effective alarm functions, which often lead to delays in the discovery and verification of related incidents, bringing great difficulties to evidence collection, rectification and investigation. In the long-term work, it is found that it is difficult to obtain good protection measures for theft of electricity, illegal operation, unauthorized operation, especially the technical theft of electricity that is gradually emerging. There are many problems. The details are as follows:

[0004] ① From the perspective of protective effect, the locks and seals currently used are more of a way to isolate operators from the operating parts of equipment, and are somewhat passive and fixed. In recent cases of technical theft of electricity, the use of counterfeit and forged seals to steal electricity has become a high incidence, and current technical measures and means lack protective effect against such operations.

[0005] ② From the perspective of protection implementation, the current control measures are difficult to intercept and deny illegal and unauthorized operations. On the one hand, in the case of electricity theft, the effectiveness of the electricity theft operation will be continued until the theft is discovered, which will bring inconvenience to the recovery of the error electricity and the punishment of the electricity theft and the violation of the electricity use, and will also seriously affect the operating performance of the metering device; on the other hand,

[0006] ③ The staff lacks the ability to protect themselves from incorrect operations. In this scenario, since the seals and locks used are normal equipment, the effects of incorrect operations will last longer and have more serious impacts.

[0007] ④ From the perspective of discovery and control mechanisms, the current control measures for operating electric energy metering devices lack active alarm and prompt capabilities. It often takes weeks, months, or even years from the occurrence of violations and unauthorized operations to their discovery. On the one hand, this creates unfavorable factors for anti-theft investigations and the pursuit of illegal electricity. On the other hand, it will also lead to serious damage to the site when investigating and punishing electricity theft and illegal and unauthorized operations, making it difficult to find clues or fix evidence. In order to solve the above technical problems, the present invention provides an RFID key management method and system for operating electric energy metering devices. Summary of the invention

[0008] The purpose of the present invention is to solve the technical problems raised in the background technology, and to provide an RFID key management method and system for an operating electric energy metering device.

[0009] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0010] A method and system for managing RFID key of an operating electric energy metering device, comprising an electric energy meter junction box with an RFID key function, a control decision module, a sensor group, an RFID reading and writing device and a remote communication module, wherein the RFID reading and writing device reads the RFID on the electric energy meter junction box with an RFID key function for identity authentication, the control decision module performs data communication with the electric energy meter with an RFID key function to monitor whether the electric energy meter with an RFID key function is illegally operated, the sensor group receives a command to start working sent by the control decision module and transmits the collected data to the control decision module, and the control decision module encrypts the collected data of the sensor group and transmits it to a remote terminal via the remote communication module.

[0011] Furthermore, the control decision module is arranged on the back of the electric energy meter junction box having the RFID key function.

[0012] Furthermore, the electric energy meter junction box with RFID key function includes a box body and a transparent box cover, the box cover can be connected to the box body as a whole by screws, the screws are provided with a seal, the box body is provided with A, B, C three-phase phase line area and N neutral line area, the A, B, C three-phase phase line area all include a voltage terminal arranged at the upper left side of the area and a voltage connecting piece located below the voltage terminal for controlling the on-off of the voltage channel, and also include a current terminal arranged at the upper right side of the area and a current connecting piece located below the current terminal for switching the current flow path, the N neutral line area is provided with a voltage terminal located at the top and a voltage connecting piece located below the voltage terminal for controlling the on-off of the voltage channel, a connecting copper bus is provided on the back of the box body, the connecting copper bus includes a voltage copper bus and a current copper bus, the voltage copper bus is electrically connected to the voltage terminal, the current copper bus is electrically connected to the current terminal, and an RFID chip is provided on the seal.

[0013] Furthermore, the sensor group includes a temperature sensor, a humidity sensor, an electromagnetic sensor and an image acquisition sensor for acquiring images.

[0014] A method for managing an electric energy meter with an RFID key function, characterized in that the method adopts the above-mentioned RFID key management system for an operating electric energy metering device, comprising the following steps:

[0015] Step 1: The decision control module determines whether the current electric energy meter junction box with RFID key function is in a non-working state. If it is in a non-working state, step 2 is executed. If it is in a working state, it is determined whether it is in an abnormal working state. If it is in an abnormal working state and it is a contactless electricity theft or a violation or unauthorized operation, step 3 is executed. If it is in an abnormal working state and it is a direct operation electricity theft or a violation or unauthorized operation, step 4 is executed.

[0016] Step 2: The junction box of the electric energy meter with RFID key function is in a dormant state, its RFID tag is not activated, no communication occurs, the image acquisition sensor of the sensor group is in a dormant state, the temperature sensor, humidity sensor and electromagnetic environment sensor of the sensor group perform measurement sampling within a certain period and send the results to the control decision module through RS-485, and the control decision module determines whether it is within the normal range. If it is determined to be normal, the current process is terminated and the above operations are repeated. If it is within the abnormal range, the data is sent to the remote terminal through the remote communication module;

[0017] Step 3: The control decision module identifies the operation signal and queries the authentication information to the electric energy meter junction box with RFID key function. The electric energy meter junction box with RFID key function starts the authority authentication. If the authentication fails, the control decision module sends an interception instruction to the electric energy meter junction box with RFID key function and starts the sensor group at the same time. The data collected by the sensor group is sent to the remote terminal through the remote communication module. If the authentication is successful, no operation is performed.

[0018] Step 4: The electric energy meter junction box with RFID key function recognizes the operation and starts the permission authentication. If the authentication is successful, the control decision module sends an interception instruction to the electric energy meter junction box with RFID key function and starts the sensor group at the same time, and sends the data collected by the sensor group to the remote terminal through the remote communication module. If the authentication is successful, no operation is performed.

[0019] The working principle and beneficial effects of the present invention are as follows:

[0020] (i) Under normal operating conditions: the energy meter junction box with RFID key function is in a dormant state, its radio frequency tag is not activated, no communication occurs, and the image acquisition sensor of the sensor group is in a dormant state to save energy. The temperature sensor, humidity sensor, and electromagnetic environment sensor take measurements and samples at regular intervals and send the monitoring results to the control decision module via RS-485. The control decision module determines whether it is within the normal range. If it is determined to be normal, the process is terminated and the operation continues; (ii) Under contactless electricity theft or illegal or unauthorized operation: Since it does not involve the operation of the energy meter junction box with RFID key function, Therefore, this component will not actively contact the control decision module. In this scenario, the control decision module will monitor the operation through the data flow of the signal loop, and send instructions to the electric energy meter junction box with RFID key function to query the operator, operating equipment and operating authority. The electric energy meter junction box with RFID key function will return information such as no identity / illegal operation because it has not been authenticated by a legitimate RFID reader / writer. The control decision module will perform three operations based on this: (1) Call the sensor group to record the data recorded by the temperature sensor, humidity sensor, and electromagnetic environment sensor at this moment and for a period of time thereafter, and wake up the image acquisition sensor to start Image data collection; (2) Self-start command interception function, actively intercept and store operation instructions in front of the power meter; (3) Call the remote communication module and command it to package and encrypt the information collected by the current sensor group and transmit it to the communication equipment of the audit management personnel through radio frequency communication and / or Bluetooth communication function, prompting relevant personnel to come to investigate or repair and preserve evidence; (iii) Direct operation type electricity theft or illegal and unauthorized operation: As the direct operation part, the power meter junction box with RFID key function starts the authority authentication function when receiving the operation / seal opening operation, and authenticates the identity information and authority information of the operator. If the identity authentication fails, If an authentication failure or permission mismatch is found, the corresponding authentication result will be sent to the control decision module. The control decision module will call the sensor group and the remote communication module in a similar manner to the scenario to collect and record information, retain evidence, and report warning information to the audit management personnel, so as to prevent and warn against abnormal behaviors such as illegal operation, wrong operation or unauthorized operation. The present invention realizes a real-time alarm function through the mutual cooperation of the electric energy meter junction box with RFID key function, the control decision module, the sensor group, the RFID reading and writing device and the remote communication module, prompting the relevant audit management personnel to come and check, thereby shortening the discovery time of electricity theft or illegal operation and retaining the audit clues.
