Description
Technical field
The utility model relates to lockset, relates in particular to a kind of normally closed type electric lock outage auto-unlocking device and has the electric lock of this device.
Background technology
In the security protection industry now, have two kinds with the supporting electric lock of gate control system: electric lock open in usual and outage normally closed type electric lock cut off the power supply.Cut off the power supply electric lock open in usual in case of emergency, and power failure is opened the door, and makes things convenient for the personnel escape.This outage 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, safety requirements than higher environment under, like bank etc., require to lock in the situation Xiamen that has a power failure, the electric lock open in usual that cuts off the power supply does not just meet these environment requirement, can not in the environment of this high safety requirements, use.Another kind is an outage normally closed type electric lock, and the normally closed type electric lock under normal circumstances keeps the state of locking a door, and does not need electric current to keep, and only when unlocking signal is arranged, just needs short-time current to unblank compliance with environmental protection requirements.But the normally closed type electric control lock is locked in the situation Xiamen of outage, and can only turn the key in the lock (under the high security context that has, does 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, like fire alarm; After outage; Key can not find, and door is not opened, and consequence is very serious.
Summary of the invention
The purpose of the utility model is to solve the problem that exists in the above-mentioned prior art, proposes a kind of normally closed type electric lock outage auto-unlocking device and has the electric lock of this device.The utility model can be realized the normally closed type electric lock is unblanked to control for the last time.
The normally closed type electric lock outage auto-unlocking device of the utility model 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 charges to electric capacity through relay through diode; To the output power supply, the normally closed type electric lock gets electric operate as normal simultaneously, and the unlocking signal of input is received output through diode and normally unblanked; When electric circuit inspection to when outage, this relay coil outage jumps to normally off, promptly output and electric capacity are connected, this moment, to the output normal power supply, unlocking signal was exported unlocking signal through relay and output connection simultaneously by electric capacity.
The utility model also proposes a kind of electric lock that has electric lock outage auto-unlocking device; This outage auto-unlocking device serial connection is between access controller and electric control lock; It is a selected on-off circuit; Under the situation of power supply normal power supply, power supply is to access controller and the power supply of normally closed type electric lock, by the switch of access controller control normally closed type electric lock; Under the situation 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; Electric lock outage this moment auto-unlocking device detects the access controller power down, unblanks for the last time after automatically the normally closed type electric lock being cut off the power supply, and makes things convenient for personnel to come in and go out, and guarantees personal security.
After the utility model had solved the gate control system outage, when can not find key, gate inhibition's main frame can not be controlled the problem that the normally closed type electric lock opens the door, and particularly suitable avoids personnel to be lockable the serious consequence that can not escape in the situation that the off-position personnel need emergency evacuation.
