Description
Technical field
The present invention relates to a kind of circuit, and in particular to a kind of safe and efficient unlocking circuit.
Background technology
Earliest lock, is the simple office that owner sets for other people anti-unlatchings, is exactly applied to simplest lock on door
Bolt, Ancient Times in China has the stone dumbbell in the form of an old-fashioned padlock, has no key, is that, with rope or iron chains constraint, Shang and Zhou Dynasty, the private ownership of the means of production is further
Development, gap between the rich and the poor is further exacerbated by, and social contradications are very prominent, at the same time, and smelting technique is ripe and is applied to immediately
Lockmaking industry, then, the copper that occurring in that could be opened with key is locked, iron is locked, and with the different locks of different key matchings.With
The fast development of science and technology, mechanical lock there has also been significant progress, and modern mechanical lockset there has been the history of more than 100 years, lock
Pellet different in size is added in core, is opened with the corresponding key of tooth form, after, coded lock, magnetic have been developed into again
Lock, electronic lock, laser lock, acoustic control lock etc., the key of these locks have added one or more groups of close on the basis of traditional keys
Code, such as alternative sounds, different magnetic field, different sound waves, different light beam light waves, different images etc., the unlatching of lock is controlled with this.
Develop into today, electric control lock has progressed into the life of people, electric control lock mainly include Fingerprint Lock, magnetic card lock, IC card lock and
Coded lock etc. electric control lock is as the action executing part of gate control system, and the quality of its quality is directly connected to the steady of whole system
It is qualitative.
As its name suggests, electric control lock can be related to circuit control, and electric control lock on the market is due to circuit control part ratio now
More complicated, expensive, simple electric control lock can lack the protection to power supply again, and secure context cannot be guaranteed.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art there is provided a kind of safe and efficient electricity of unlocking
Road, its energy volitional check power-on time, and effectively power supply is played a protective role, not only simple but also safety.

Switch is unclamped again, unclamps after hand switch, and power supply is further continued for the first electric capacity and the charging of the second electric capacity, until being full of；Its
It is secondary, do not put if pinning hand switch always, because the second electric capacity is constantly in discharge condition, when the voltage at the second electric capacity two ends
Less than the release voltage of relay, then the second electric switch disconnection, electric control lock power-off, so as to serve volitional check power-on time
Effect, is only unclamping hand switch, the first electric capacity and the second electric capacity are refilled after electricity, could unlocked again, therefore rise
The effect of protection power supply has been arrived, it is simple and safe.
Further, also including the second diode, second diode is light emitting diode, and the second Diode series exist
On the circuit that first resistor is connected with the first electric capacity, and the positive pole of the second diode is relative with the first electric capacity connects full-wave rectification bridge
The other end be connected, the negative pole of the second diode is connected with first resistor.By setting light emitting diode, prompting can be played and made
With indication circuit is ready, in normal operating conditions.
Further, also including fuse, one end of the fuse is connected with one end of transformer first siding ring, is melted
The other end of disconnected device as the unlocking circuit an input.By setting fuse in circuit, excessively stream can be played
Protective effect, can be prevented effectively from the excessive electronic device burnt out in power circuit of peak current during because of city's electro-mechanical wave.
The present invention compared with prior art, has the following advantages and advantages：1st, the present invention can be supplied with volitional check
The effect of electric time, and the effect of protection power supply is served, it is simple and safe；2nd, can by setting fuse in a power
To play overcurrent protection, the excessive electronics device burnt out in power circuit of peak current during because of city's electro-mechanical wave can be prevented effectively from
Part；3rd, by setting light emitting diode, suggesting effect can be played, indication circuit is ready, in normal operating conditions.
