A five-proof smart lock authorization verification method for outdoor equipment in distribution network

Abstract

The invention provides a five-prevention smart lock authorization verification method for a distribution network outdoor device. The method is implemented by a management server, a smart lock and an electronic key. The method includes the steps that an electronic key unlock authorization and verification mechanism is implanted in the management server and the smart lock; the management server encodes relevant information and performs encoding operation to form an unlocking key; the electronic key acquires the unlocking key and unlocking authorization information; the electronic key is insertedin and starts the smart lock and sends unlocking information to the smart lock; and the smart lock calculates a verification key and performs key comparison verification to determine whether to perform unlocking action. By introducing time information into a smart lock authorization and verification mechanism, unlocking accuracy and timeliness can be ensured, and potential safety hazards and shortcomings of a smart lock in the prior art are effectively overcome.

Description

technical field [0001] The invention relates to a protective lockset for distribution network equipment, in particular to an authorization verification unlocking method for an intelligent lock for five-proof outdoor equipment in a distribution network. Background technique [0002] In the power system, five preventions usually refer to the abbreviation of five anti-error functions for high-voltage electrical equipment to ensure personal safety, and it is one of the important measures for power safety. There are a large number of outdoor equipment in the distribution network, such as ring network cabinets, etc., which need to be protected by locks to prevent losses or accidents caused by unrelated personnel opening the equipment. At present, the locks used in outdoor distribution network equipment are usually mechanical padlocks. Since there are a large number of locking devices such as ring network cabinets and community substations in the same area, the number of padlocks i...

Problems solved by technology

At present, the locks used in outdoor distribution network equipment are usually mechanical padlocks. Since there are a large number of locking devices such as ring network cabinets and community substations in the same area, the number of padlocks is large. If each lock has a specific corresponding Keys, inspectors need to carry a large number of keys during outdoor inspections. On the one hand, it is inconvenient to carry. On the other hand, when they need to unlock and check the equipment, they need to search for the corresponding key among a large number of keys, which is time-consuming and labor-intensive.

In order to solve this problem, the current practice of the power supply department is to use the same key to unlock the padlocks of the outdoor equipment in the same area, which can effectively solve the problems of inconvenient carrying a large number of keys and time-consuming rummaging for keys. However, it brings The new problems are: First, there are hidden dangers of misoperation. Taking the common ring network cabinets on the streets and roads as an example, since there are often many ring network cabinets on the same street (road), and the shape and color of the ring network cabinets are basically the same, Although there is a number plate on the ring network cabinet, when the number plate is unclear or falls off, or the inspection personnel are negligent, the ring network cabinet A should be opened for maintenance or operation, but the ring network cabinet B is opened, and the power distribution equipment is wrong. The operation will bring economic losses and adverse effects, and even cause injury accidents in severe cases; second, there are problems such as being stolen by illegal personnel (copper) and man-made damage to the outdoor equipment of the distribution network due to the loss and duplication of keys. other security risks

[0003] In order to overcome the problems of the above two solutions, the power supply department is currently trying to install smart locks that can be unlocked with electronic keys on the outdoor equipment of the distribution network. Such smart locks generally have their own power supply and are not connected to the Internet. Before the outdoor equipment of the power grid, a fixed unlocking authorization verification information is built into the processor of the smart lock; any electronic key with the unlocking authorization information of the smart lock can open the smart lock; the existing problems are: one , when the electronic key carrying the authorization information of the smart lock is lost, the authorization information will also be leaked, which will bring security risks such as being stolen by illegal personnel and man-made damage to the outdoor equipment of the distribution network; secondly, the unlocking authorization of the electronic key There is no time limit, and the electronic key after obtaining the unlock authorization can open the corresponding smart lock at any time. The disadvantage is that on the one hand, it cannot meet the management needs of the power supply management department for the time-limited inspection of outdoor power supply equipment in the distribution network; There are safety hazards such as missing inspections and outdated inspections
