Description

Substation "five defenses" universal unlock key smart box

technical field

The utility model belongs to the technical field of "five defenses" in electric power systems, in particular to a smart box with "five defenses" universal unlocking key for substations.

Background technique

"Five-proof" locking devices are widely used in modern power systems, and the "five-proof" devices are used to avoid various misuse accidents, and the unlock key is an important part of the "five-proof" devices. Due to the lack of maintenance of the "five-defense" locking device, the computer key program sometimes becomes confused, which makes it impossible to use the key to unlock the lock according to the steps. In addition, in order to shorten the processing time, reduce power outages and equipment damage in accident handling or abnormal situations, it is necessary to Operations under non-program conditions require the use of the "five defenses" master key. However, the non-standard use of the "five-defense" master key, or the unauthorized expansion of the use of the master unlocking key, has led to frequent misuse accidents and caused many hidden dangers to safety.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a "five-defense" universal unlocking key smart box for substations that has a simple structure, is easy to operate, is safe and reliable, and prevents unauthorized use of the universal unlocking key.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the substation "five-defense" universal unlocking key intelligent box includes a box body, and a microcomputer control machine and a universal unlocking key are arranged in the box, and the surface of the microcomputer control machine is provided with The display screen, selection button and number button are provided with a box door on the box body, and an electromagnetic lock is arranged at the opening and closing of the box door, and the electromagnetic lock is connected with the microcomputer control machine through a signal line.

A support is provided in the box, and a position sensor is provided on the support. The position sensor is connected with the microcomputer control machine through a signal line, and the universal unlocking key is placed on the support and contacts with the position sensor.

A piece of glass is clamped in the middle part of the door.

Using the above technical scheme, the universal unlocking key is placed in the box, and the unauthorized use of the universal unlocking key is prevented from the hardware. When the universal unlocking key needs to be used, the on-duty personnel verbally or by telephone applies to the supervisor and gives a password number after the approval of the responsible person. The box can be opened by operating the selection button and the number button. Every time it is opened, a password is required, and the password for unlocking the box will automatically change next time. When the password is entered incorrectly for 5 times in a row, the microcomputer control will lock the door, and it will automatically lock each time it is opened. Record each opening date, authorizer, user information and other data.

The opening and closing of the box door of the utility model is controlled by a microcomputer controller, which has the advantages of simple structure, small size, low power consumption, strong control function, and flexible expansion; the box management process is simple, and records can be checked; the box power supply uses a DC system, Not afraid of power outages; thousands of passwords are stored in the microcomputer control machine, and the passwords are stored in the password device, which is easy to find; a piece of glass is installed in the middle of the door. operation of the "anti" locking device. The utility model utilizes modern microcomputer technology, has reasonable design, simple structure, easy operation, convenient management, strong practicability and easy popularization and application.

Detailed ways

As shown in Figures 1 and 2, the substation "five-defense" universal unlocking key intelligent box of the present utility model includes a box body 4, and a microcomputer control machine 10 and a universal unlocking key 7 are arranged inside the box body 4, and the surface of the microcomputer control machine 10 is It is equipped with display screen 2, selection button and number button 3. The display screen 2 has power-saving protection function. It is usually black screen protection. When in use, it displays management process information and records. The selection button includes six buttons with certain functions, and the number button 3 includes keys with ten Arabic numerals from 0 to 9 respectively marked on the surface. Casing 4 is provided with chamber door 11, and a piece of glass 5 is clamped in the middle part of chamber door 11, and chamber door 11 opening and closing place is provided with electromagnetic lock 6, and electromagnetic lock 6 is connected with microcomputer control machine 10 by signal line. The casing 4 is provided with a support 8, the support 8 is provided with a position sensor 9, the position sensor 9 is connected with the microcomputer control machine 10 by a signal line, and the universal unlocking key 7 is placed on the support 8 and contacts with the position sensor 9.

Button 1-1 is an optional key for the authorizer, and the information of the authorizer is digitally coded, which is realized by digital button 3. Button 1-2 is an optional key for using the universal unlocking key 7 reasons, and the reason content information is a digital code, which is realized by the digital button 3. Buttons 1-3 are keys that can be selected by the user, and the information of the user is a digital code, which is realized by the digital button 3.
