Portable key management box, key management system and usage method

Abstract

The invention relates to a portable key management case, a key management system and their application methods. The portable key management case comprises an openable case body, a mounting terrace, a locking unit, a power supply module and a key; the mounting terrace is arranged in the case body, the locking unit has a locking sheet, a locking body, a control body and an identification module, the identification module is electrically connected with the control circuit, the control circuit controls the locking body to lock or unlock the locking sheet, the locking sheet is fixed to the mounting terrace when locked and may be released from the mounting terrace when unlocked, the power supply module is electrically connected with both the control circuit and the identification module, and one end of the key is connected with the locking sheet. The portable key management case can be mounted on a vehicle and is also available for wireless and smart locking; the problem that unlocking keys are inconvenient to store, use and manage due to the gradual development of unattended substations.

Description

technical field [0001] The invention belongs to the field of intelligent key management in electric power systems, in particular to a vehicle-mounted or portable key management box in the electric power industry, a key management system and their usage methods. Background technique [0002] It is well known in the industry that in the field of safety management in the electric power industry, the use of more microcomputer error prevention systems involves the use of emergency unlocking keys. Because this emergency unlocking key can be opened universally, it is generally subject to strict use management. The usual practice Including the use of an unlock key storage box or a more intelligent unlock key management machine. [0003] The storage box and the unlocking key management machine are generally installed in the main control room of the substation. The management mode is managed by sticking a seal or authorized to open the management machine by swiping a card or SMS, and ...

AI Technical Summary

Problems solved by technology

With the implementation of unattended substations, often one operation and maintenance team will manage multiple substations, which causes inconvenience when emergency keys need to be activated. Because different substations may belong to different suppliers, different microcomputer error prevention systems are provided. The unlocking key is naturally different. The unattended operation area is generally far away from the original storage area where the unlocking key management box is stored, so it brings a lot of inconvenience to the emergency use of the key or the access management of the key.
