Passive padlock management method and system and key

Abstract

The invention discloses a passive padlock management method and system and a key. The system comprises a plurality of keys, a cloud system and a plurality of passive padlocks associated with a plurality of power distribution websites in a one-to-one correspondence manner. Each passive padlock comprises an RF chip and a door control circuit. Each door control circuit is connected with a serial port, and the keys are in contact with the RF chips and are electrically connected with the serial ports after being inserted into key ports. After the key is inserted into the key hole, the door lock identifier in the RF chip is read, the read door lock identifier is sent to a cloud system and an unlocking password returned by the cloud system is received. Power is supplied to the gate control circuit through a serial port. The unlocking password is sent to the gate control circuit through a serial port. The cloud system, the key and the passive padlock are subjected to deep joint customization,the problems that a traditional mechanical lock is difficult to manage, low in efficiency and the like are solved. Intelligent management of power distribution network equipment is achieved, the riskof field operation is reduced, the working efficiency of key management and authority control is improved, and safety management and control over an operation field are enhanced.

Description

technical field [0001] The invention relates to the field of power distribution stations, in particular to a passive padlock management method, system and key. Background technique [0002] With the expansion of the city, the scale of the urban distribution network is also increasing. Since distribution network equipment is connected to thousands of households, the safety management of distribution network equipment is a difficult problem faced by distribution operation and maintenance management units. Traditional distribution network equipment mainly relies on traditional mechanical padlocks for management, which have the characteristics of simple structure and fast installation. However, with the expansion of the grid scale, key management for mechanical padlocks requires a lot of manpower and physical management. And in the temporary emergency repair state, it takes a lot of time and energy to go back and forth to the power supply station to get the key, which prolongs...

AI Technical Summary

Problems solved by technology

[0003] In general, traditional mechanical locks have the following defects: on-site monitoring cannot be completed, and it is impossible to manage whether the operator unlocks the lock himself; the mechanical key is low in security and easy to reuse, and the operator copies the key at will, which makes management difficult; traditional mechanical lock management The cost is high, and the power grid operation and maintenance unit needs to assign a special person to manage the keys in a unified manner, and the access time is long; the operation efficiency is low: the traditional padlock is managed by a special person, and in the case of emergency repair, the repair personnel still need to go back and forth to retrieve the key to go On-site work is time-consuming and labor-intensive
