Method and device for unlocking key management box on basis of fingerprint identification technology

Abstract

The invention relates to a method for an unlocking key management box on the basis of a fingerprint identification technology. The method comprises the steps: monitoring a door and a key of the unlocking key management box by virtue of an electric power remote control channel; unlocking on site if an unlocking key is needed on site and specified people or equivalent permission people are available on site; monitoring whether the unlocking key is returned or not by virtue of infrared detection after unlocking operation is successful, the unlocking key is taken out and relevant operations are completed; completing the unlocking if the unlocking key is returned; forcedly locking the box door if the unlocking key is not returned. The unlocking on site can be carried out by adopting a way for recording fingerprints and inputting a password, the separation of people, card and password can be prevented, the remote monitoring, recording and unlocking can be carried out by the dispatching personnel, and the unlocking key management box can dynamically monitored from a long distance safely and efficiently by virtue of special optical-fiber communication for an electric power system, the box door cannot be locked if the key is taken away, and the application of the key can be supervised while the problem of false door locking can be avoided. The invention also discloses a device for an unlocking key management box on the basis of the fingerprint identification technology.

Description

technical field [0001] The invention relates to the technical field of power grid monitoring, in particular to a method and device for unlocking a key management box based on fingerprint identification technology. Background technique [0002] At present, high-voltage unattended substations are equipped with microcomputer error prevention operating systems, which are necessary safety protection for the safe operation of the power grid. However, when there is a failure of the microcomputer anti-misoperation locking device, skip operation and non-important maintenance are required, that is, when auxiliary equipment for power production needs to be unlocked, the unlocking key must be used, and the use of the universal unlocking key in violation of regulations is the most serious cause of personal injury accidents caused by misoperation. main reason. According to the new requirements of substation operation and management since 2013, the use of unlocking keys must be unlocked b...

Problems solved by technology

[0003] Furthermore, the unlocking key of the substation has been updated from the management method of sealing the envelope used in the past to the level of using a partly intelligent unlocking key management box. A serious problem: 1) Almost all existing unlocking key management boxes use CPU structure and (GPRS) GSM communication module. According to theoretical research and operation accident experience, GSM communication will cause serious radio interference to the relay protection equipment in the main control room Therefore, the current operating regulations even prohibit the use of wireless communication equipment such as mobile phones in the main control room. In addition, power wireless communication equipment rarely passes the strict communication YD / T 1484 series test certification, and relay protection equipment is exposed to strong GSM wireless interference environments. There are huge hidden dangers in operation; 2) GSM module communication is rented by the operator's public network, and the function is limited to SMS unlocking, the process lacks verification and records, and there is no management measure for the return of the key after use, so as to prevent error information production control information , the opening and closing information and control of the box should be reported to the dispatching and communication bureau in time

According to the "Overall Plan for Informatization Security Protection of Power Grid Companies", such information needs to be transmitted through the internal optical fiber network of the power system telecontrol to ensure real-time and reliable information; 3) The existing unlocking boxes are all integrated designs. Next, you can smash a large piece of glass on the box panel to obtain a master unlocking key (called emergency unlocking), but doing so will cause economic losses, increase maintenance costs and time, and also easily damage the master key

At the same time, the large piece of glass occupies most of the panel of the cabinet, which limits the expansion of more advanced functions of the cabinet; 4) In addition to the remote unlocking of the existing management box, which does not have the remote unlocking of the dispatching console, its local unlocking is all operated by swiping cards or passwords. It is easy to separate people, cards, and passwords, and the management of the master key may not be on site to unlock the key box at all, losing the supervision of the master key

Therefore, most power supply enterprises do not allow on-site unlocking during operation, which seriously reduces the efficiency of maintenance operations
