Charge management device for smart key

Abstract

In order to improve the safety and reliability of transmission equipment, the electric power department introduces the intelligent locks into the safety management and control of the electric power field, However, the self-contained rechargeable battery of the existing smart key itself cannot clearly display the charging status of the smart key and power-off the full smart key to prevent overcharge, A management device for char an intelligent key Integrated wireless communications, Clock Management, bidirectional current / power monitoring, SCM control, technology such as liquid crystal displaysand resistive touch-screen controls, having a switch that controls the charging power supply, As that char voltage and the current value are detected during the charging process, Judging the chargingprocess, Battery charge, setting charging countdown, automatic power off after charging and charging end reminder can effectively control the charging process of the smart key, ensure the charging safety of the smart key, prolong the service life of the smart key, reduce the attention of the staff in the charging process of the smart key, and improve the work efficiency of the staff.

Description

technical field [0001] The invention relates to a charging device for a smart key used in a smart door lock at a power site (substation, power distribution room, switching station, etc.), in particular to a charging management device for a smart key. Background technique [0002] At present, the power sector is gradually introducing smart locks into the security control of entrances and exits of power sites such as substations, power distribution rooms, and switching stations. The application of intelligent locks realizes the functions of time period management, area management, real-time monitoring of the status of the portal, intelligent identification of entering personnel and other functions for entering the power site, which can effectively solve the problem of unauthorized entry and unauthorized manipulation of traditional open locks. Management responsibility to ensure safe production provides an effective technical measure, which is conducive to safer, reliable and e...

AI Technical Summary

Problems solved by technology

[0003] The display method of the battery power of the existing smart key itself is not clear, and it is prone to the problem that the power of the smart key is insufficient during use and the lock cannot be unlocked. At the same time, there is a lack of real-time monitoring of the charging process of the smart key during the charging process, and the smart key cannot be clearly displayed. The charging state (such as: required charging time, charged time, battery power, etc.), charging current, cannot power off the fully charged smart key and prevent overcharging, which brings safety hazards to field use and reduces work efficiency.
