Description

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

technical field

The invention relates to a protection lock for power distribution network equipment, in particular to a smart lock authorization verification unlocking method for five-proof power distribution network outdoor equipment.

Background technique

In the power system, five defenses usually refer to the abbreviation of five anti-error functions for high-voltage electrical equipment to ensure personal safety, which 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 setting locks to prevent unrelated personnel from opening the equipment and causing losses or accidents. 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 residential substations in the same area, the number of padlocks is very large. If each lock has a specific corresponding lock Keys, inspectors need to carry a large number of keys during outdoor inspections. On the one hand, it is inconvenient to carry them. 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 locked outdoor equipment in the same area, which can effectively solve the problems of inconvenience to carry a large number of keys and time-consuming to unlock and search for keys. The new problems are: First, there are hidden dangers of misoperation. Taking the common ring network cabinets on the street and roadside as an example, because 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, in the case of unclear or falling off of the number plate, negligence of the inspection personnel, etc., 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. Operation will bring economic losses and adverse effects, and even cause injury accidents in serious cases; secondly, there is a loss of keys and duplication of the outdoor equipment of the distribution network, such as theft by illegal personnel (a lot of copper) and vandalism. and other safety hazards.

In order to overcome the problems of the above two solutions, the power supply department has begun to try to set up smart locks 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 power grid outdoor equipment, 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 is also leaked, which brings security risks to the outdoor equipment of the distribution network, such as being stolen by illegal personnel and man-made damage; second, the unlocking authorization of the electronic key There is no time limit. The electronic key after obtaining the unlocking 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 the outdoor power supply equipment of the distribution network. There are safety hazards such as missed inspection and outdated maintenance.

Referring to FIG. 3 and FIG. 4 , in step ⑤ of the aforementioned method, after the electronic key 100 is inserted into the electronic key hole 4-1 of the lock cylinder 4 of the smart lock, the electronic key 100 passes through the 2 of the socket part 100-2 of the housing. The output electrodes 100-4 are electrically connected to the two input electrodes 10-2 of the electronically controlled unlocking assembly 10 of the smart lock through the two conductive beads 4-4 of the lock cylinder 4; Electronic key, the electronically controlled unlocking assembly 10 of the smart lock starts to work when the electronic key 100 is powered on:
