Security certification method and security certification device for power grid equipment and negative control terminal

Abstract

The invention discloses a security certification method and a security certification device for power grid equipment and a negative control terminal. The method comprises the following steps: receiving electric power information comprising security certification data and instruction data and sent by master station equipment in a power grid; performing security certification on the power grid equipment according to the security certification data to generate a security certification result; and executing the operation corresponding to the instruction data according to the security certification result. The invention also discloses the security certification device for the power grid equipment. The device comprises an information receiving unit, a security certification unit and an instruction execution unit, wherein the information receiving unit is used for receiving the electric power information comprising the security certification data and the instruction data and sent by the master station equipment in the power grid; the security certification unit is used for performing security certification on the power grid equipment according to the security certification data to generate the security certification result; and the instruction execution unit is used for executing the operation corresponding to the instruction data according to the security certification result. Simultaneously, the invention also discloses the negative control terminal.

Description

technical field [0001] The invention relates to the field of load control terminals, in particular to a safety authentication method and a safety authentication device for power grid equipment, and also to a load control terminal. Background technique [0002] The collection of electric energy information is an important part of the modern electric power marketing system. The traditional electric power settlement relies on manual work to regularly fetch data from the site, which has many deficiencies in terms of real-time performance, accuracy, and applicability. The load control terminal is the equipment that performs power information collection. It is mainly used for the collection of power information at each information collection point, and can also be used for data management, data transmission, and execution or forwarding of control commands issued by the master station to realize Automatic collection of electric energy information and remote control of monitoring ob...
