A digital token-based virtual card reset instruction transmission method and device

Abstract

The invention discloses a method and a device for transmitting a power recovery instruction of a virtual card based on a digital token. The method includes: a power recovery command generating module generates a remote power recovery command; a digital token encryption module encrypts the remote power recovery command and The encrypted transmission key is encrypted, and a ciphertext digital token is generated; the digital token sending module converts the ciphertext digital token into a two-dimensional code digital token, and sends the two-dimensional code digital token to the user. The electricity user; the electricity user displays the two-dimensional code digital token on the recovery terminal; the recovery terminal restores the two-dimensional code digital token to the ciphertext digital token, and sends to the security chip in the terminal; the security chip restores the ciphertext digital token to the remote power restoration command; the power restoration terminal sends the remote power restoration command to the smart cost-controlled electric energy meter, and the power restoration The intelligent cost-controlled electric energy meter completes the authentication and power recovery operation. In the implementation of the present invention, a convenient and quick power recovery service is provided.

Description

technical field [0001] The present invention relates to the technical field of metering automation, and in particular, to a method and device for transmitting a digital token-based virtual card power-recovery instruction. Background technique [0002] The power grid company's low-voltage power distribution station has a wide range of locations, complex on-site environment, a large number of metering automation module equipment and a large amount of data, and the communication channel of metering automation module in some areas, especially in the old, young, border and poor areas, is close to saturation; with the explosive growth of new demand for metering automation , the extensive use of remote cost control makes the already overburdened measurement automation module communication network more difficult. The existing remote power recovery method completely relies on the communication channel of the metering automation module to transmit the power recovery command. Since the...

Problems solved by technology

[0002] The power grid company's low-voltage distribution stations have many points and wide areas, the on-site environment is complex, and the number of metering automation module equipment is large, and the data volume is large. In some areas, especially the old, young, frontier and poor areas, the communication channel of the metering automation module is close to saturation; with the explosion of new demand for metering automation , the extensive use of remote fee control makes the already overwhelmed metering automation module communication network more difficult

The existing remote power restoration method completely relies on the communication channel of the metering automation module to transmit the power restoration command. Since the communication channel of the existing metering automation module is easily affected by the external environment, the power restoration success rate and response speed cannot meet the user's power response requirements. , have a certain impact on the service image of the power company

Therefore, in the current situation where the communication network of the metering automation module cannot be upgraded and expanded on a large scale, there is an urgent need for a remote offline power recovery technology that can effectively compensate for the lack of communication capabilities of the metering automation module. Reduce the pressure on the communication between the cost-controlled electric energy meter and the metering automation module
