Problems solved by technology

However, the anti-misoperation locking device is equipped with a universal unlocking key. Judging from the actual operation of the substation, illegal use of the unlocking key occurs from time to time.
The direct consequence of using the master unlock key in the switching operation may lead to misoperation
Hiding the unlocking key privately, forcibly unlocking it, or failing to perform the procedures and procedures for unlocking the key may cause misoperation
However, the current management of the master key is not standardized, and there are problems such as private use and inability to monitor the work area. If the network fingerprint authority control is used, this problem can be solved well, and it will play a role in improving the safety management level of substations and improving the reliability of power grid operation. important role

Abstract

The invention relates to an unmanned substation universal unlocking key fingerprint network authorization system which is characterized in that: the system comprises a server, a communication unit, a controlling machine and a control box; wherein an electric lock is arranged on the control box, the controlling machine comprises a fingerprint acquisition unit and a fingerprint information processing unit, the signal output end of the fingerprint acquisition unit is connected with the signal input end of the fingerprint information processing unit, the control signal output end of the fingerprint information processing unit is connected with the control end of the electric lock on the control box, and the server is communicated with the controlling machine by the communication unit; the invention further provides an unmanned substation universal unlocking key fingerprint network authorization method, after the fingerprint is verified to be matched, and then a server application authorization code way is used, so as to greatly improve the safety of key management and eliminate miss operation owning to privately using the universal key.

Description

technical field [0001] The invention relates to a fingerprint network authorization system and method for a universal unlocking key of an unattended substation. Background technique [0002] At present, with the continuous development of the comprehensive automation technology of substations, at present, the urban grids of various cities in my country have established 110 kV centralized control centers, and most of the substations of 110 kV and below in urban areas have achieved unattended, gradually forming highly automated modernized power grid. The unattended substation has completely changed the original human-on-duty mode from the machine-plus-network on-duty mode. [0003] As an important equipment to ensure the safe operation of electric power, the five-proof locking device has been generally recognized in the electric power sector. However, the anti-misoperation locking device is equipped with a universal unlocking key. Judging from the actual operation of the subst...
