Electronic coded lock low-electric-quantity stable locking method and electronic coded lock low-electric-quantity stable locking device

Abstract

The invention discloses an electronic coded lock low-electric-quantity stable locking method and an electronic coded lock low-electric-quantity stable locking device. With the adoption of the method,a coded lock is powered through a backup power source, and a power source is cut in time, so that the safety of the coded lock can be ensured effectively; the device comprises a power source detectioncontrol panel and the backup power source; the power source detection control panel comprises voltage signal collection circuits connected in parallel, current signal collection circuits connected inseries, a power source output control circuit and a power source charging circuit; detection, control and outage compensation of working voltage are achieved through a positive electrode connected into the power source in series; and the problem that the electronic coded lock can not be locked due to low power or man-made outage after being unlocked is solved.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to a method and device for stably locking an electronic combination lock with low power. Background technique [0002] The electronic combination lock is a low-power working device, and has low-battery reminder and alarm functions. However, in actual use, due to the noisy working environment on site and the lack of responsibility of the staff, the reminder and alarm of the electronic combination lock are often ignored. Neglect, when the battery is low, it is easy to re-lock after unlocking due to insufficient power, resulting in the failure of safes or other important storage devices to automatically lock after opening the door, causing major safety hazards. In addition, after the electronic combination lock is unlocked, if the lock body power supply of the electronic combination lock is artificially cut off, the electronic combination lock will not be able to lock, which can cause m...
