RFID key management method and system for operating electric energy metering device

Abstract

The invention relates to the technical field of electric energy meters, and concretely relates to an RFID key management method and system for operating an electric energy metering device. The systemcomprises an electric energy meter junction box with an RFID key function, a control decision module, a sensor group, an RFID read-write device and a remote communication module, the RFID read-write device reads RFID on the electric energy meter junction box with the RFID key function for identity authentication, the control decision module is in data communication with the electric energy meter with the RFID secret key function so as to monitor whether the electric energy meter with the RFID secret key function is illegally operated or not, the sensor set receives a command, sent by the control decision module, for starting working and transmits collected data to the control decision module, and the control decision module encrypts the collected data of the sensor group and transmits theencrypted data to a remote terminal through the remote communication module.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to an RFID key management method and system for an operating electric energy metering device. Background technique [0002] According to the measurement law and technical standards, the electric energy metering device should be installed at the boundary of property rights, that is, the boundary between the assets of the customer and the power supply company. From this perspective, the electric energy metering device is naturally close to the customer. On the other hand, it is In other words, the electric energy metering device is used as the direct basis for the electric energy transaction between the power supply and the consumer, and only authorized personnel are allowed to perform operations and tests within a limited range. High risk of electricity theft or breach of contract, it can be seen that the implementation of key and authorization management for on-site o...

Problems solved by technology

[0003] At present, the on-site operation of metering devices is usually protected by technical measures of applying seals, that is, installing a closeable cover or box on the operating part of the metering device, and installing a special seal on the switch. Once the seal is disassembled, it cannot be reused. However, the structure of the seal itself is relatively simple and lacks necessary anti-counterfeiting measures. In recent years, the unauthorized operation of metering devices and the resulting hidden dangers of electricity theft/breach of contract and safety hazards have shown an upward trend. Traditional seals are difficult to fundamentally prohibit illegal operations. , also lacks an effective alarm function, which often leads to a lag in the discovery and verification of related events, which brings great difficulties to evidence collection, rectification and investigation. The rising technology stealing and other issues have achieved good protection measures, and there are many problems. The details are as follows:

[0004] ① From the perspective of protection effect, the locks and seals currently used are more in the way of isolating the operator and the operation part of the equipment, which has a certain degree of passivity and immobility. The situation of stealing electricity by sealing has shown a high incidence trend, and the current technical measures and means lack the protective effect on such operations

[0005] ② From the point of view of protection implemen...
