Description
Technical field
The present invention relates to lock technology field, electronic lock that specifically a kind of two-wire system can communicate.
Background technique
Conditional electronic lock, usually only there is the inductor of monitoring pick-proof lock on outdoor panel, and the demand to sensor is small；Energy
The electronic lock for enough connecting network, generally also only increases door sensor inductor in lock body, is communicated to the information of cell phone application only are as follows:
Whether door lock shuts.But if there are many system point for needing to monitor in the lock body of lockset, the number of sensors used accordingly increases
In the case where more, each sensor conveys information to control system, line by the way of both threads in narrow space
The installation, maintenance for giving lockset is excessively brought huge trouble by beam, and safety, stability are bad, and service life is short.
In existing electronic lock body, usually only has one group of motor driven line (two lines), if having additional signal
When detection demand, the signal wire of lock body external connection is also increased while increasing detection sensor.When detection sensor compares
When more, it will lead to that harness is more, it is excessive to eventually result in the connector volume that lock body is connect with indoor outer panels, peace of visiting
Secondary aperture is caused when dress, generates extra charge, influences to install.
Meanwhile in existing electronic lock body, it can be driven to motor driven line (two lines) one positive one negative voltage
Motor rotates forward (or reversion)；To the positive voltage of motor driven line (two lines) negative one can driving motor reversion (or just
Turn).Since the connector that lock body is connect with indoor outer panels is located in the door opening of installation lock body, when illegal invasion personnel are broken
Break down panel outside lockset room when, by the lockset mounting hole on door, just can touch motor driven line (two lines), simply apply
The illegal rows such as making alive can both drive lock body clutch motor, and then open the main lock tongue of lock body, and implementation burglary, robbery are extorted
For this driving method has great security risk.
Summary of the invention
Purpose of design of the present invention is: in view of existing intelligent electronic lock hidden danger huge present on safety and harness compared with
The problems such as more electric wire installation maintenances is inconvenient, we, which design, provides a kind of electronic lock that two-wire system can communicate.In the present invention, it adopts
Electricity both may be implemented so that the connection between lock body and indoor outer panels only has both threads with the design method of " modulating/demodulating "
Source transmission, also may be implemented data communication, can convert digital signal for the signal that sensor each in lockset is spread out of, send
To the lockset control panel for using this lock body, without increasing additional harness, installation while supporting multiple sensors
It is convenient.
In the present invention, lock body motor is to need to send using the lockset control panel of this lock body by " modulating/demodulating "
" forward/reverse " communication instruction carries out control driving, and simply to apply voltage can not drive lock body clutch motor, because
This facilitates home life with very high safety.
To achieve the above object, the present invention adopts the following technical scheme:
