Abstract
The invention discloses an automatic electric lock power-failure unlocking device and an electric lock with the same. The automatic power-failure unlocking device is connected in series between an entrance guard controller and an electric control lock and serves as an option switch circuit; under the condition that a power supply supplies power normally, the power supply supplies power to the entrance guard controller and the normally closed electric lock, and the entrance guard controller controls switching on and switching off of the normally closed electric lock; under the condition that the power supply is switched off, the power supply stops supplying power to the entrance guard controller and the normally closed electric lock, and the entrance guard controller cannot control the switching on and the switching off of the normally closed electric lock; when detecting the power failure of the entrance guard controller, the automatic electric lock power-failure unlocking device automatically unlocks the normally closed electric lock for the last time before power failure, so people can get and out from an entrance conveniently and the safety of the people can be guaranteed.
Description
Technical field
The present invention relates to lockset, relate in particular to a kind of normally closed type electric lock power-off auto-open-lock device and with the electric lock of this device.
Background technology
In security protection industry now, the electric lock supporting with gate control system has two kinds: power-off electric lock open in usual and power-off normally closed type electric lock.Power-off electric lock open in usual in case of emergency, open the door, and facilitates personnel escape by power failure.This power-off electric lock open in usual needs certain follow current could keep door lock state under normal operation, very power consumption, and in the today of advocating low-carbon environment-friendly, obvious this electric lock is not good selection.In addition, in the higher environment Xia，Ru bank of safety requirements etc., require to lock in the situation Xiamen having a power failure, power-off electric lock open in usual does not just meet the requirement of these environment, can not in the environment of this high safety requirements, use.Another kind is power-off normally closed type electric lock, and normally closed type electric lock keeps the state of locking a door under normal circumstances, does not need electric current to maintain, and only when having unlocking signal, just needs short-time current to unblank, and meets environmental requirement.But normally closed type electric control lock is locked in the situation Xiamen of power-off, can only turn the key in the lock (under the high security context having, do not allow to install mechanical lock, can only be by door open button, swipe the card or password opens the door), in case of emergency, as fire alarm, after power-off, key can not find, and door is not opened, and consequence is very serious.
Summary of the invention
The object of the invention is to solve above-mentioned problems of the prior art, propose a kind of normally closed type electric lock power-off auto-open-lock device and with the electric lock of this device.The present invention can realize normally closed type electric lock is unblanked to control for the last time.
The normally closed type electric lock power-off auto-open-lock device of the present invention's design is a selected on-off circuit, comprise a relay, the adhesive when normal power-up of this relay, the common port pin of relay and Chang Kaiduan pin are connected, power supply by diode through relay to capacitor charging, to output power supply, normally closed type electric lock obtains electric normal operation simultaneously, and the unlocking signal of input is received output by diode and normally unblanked; When electric circuit inspection is when the power-off, this relay coil power-off jumps to normally off, and output and electric capacity are connected, now by electric capacity to output normal power supply, unlocking signal is connected by relay and output simultaneously, exports unlocking signal.
The present invention also proposes a kind of electric lock with electric lock power-off auto-open-lock device, this power-off auto-open-lock device is serially connected between access controller and electric control lock, it is a selected on-off circuit, the in the situation that of power supply normal power supply, power supply, to access controller and the power supply of normally closed type electric lock, is controlled the switch of normally closed type electric lock by access controller; The in the situation that of power cut-off, power supply stops access controller and the power supply of normally closed type electric lock, the switch of the uncontrollable normally closed type electric lock of access controller; Now electric lock power-off auto-open-lock device detects access controller power down, automatically normally closed type electric lock is carried out unblanking for the last time after power-off, facilitates personnel to come in and go out, and guarantees personal security.
The invention solves after gate control system power-off, while can not find key, gate inhibition's main frame can not be controlled the problem that normally closed type electric lock opens the door, and particularly suitable needs the situation of emergency evacuation off-position personnel, avoids personnel to be lockable the serious consequence that can not escape.
