Description
Technical field
The invention belongs to safety-security area, particularly relate to a kind of security device of intelligent antitheft mechanical lock.
Background technology
Existing smart home security technology is mainly applied on door lock.For security consideration, China's regulatory authorities requires which kind of mode home security door lock adopts all to leave this door-opening mode of mechanical lock, namely needs to leave traditional keys and opens the door.
And the mechanical door-opening mode of existing Smart Home door lock is all mechanical lock directly exposes, then unblanked by traditional method for unlocking, objectively just provide users with the convenient like this, but for the safety not substantial raising of domestic door lock, easily allow the direct picking lock of unprincipled fellow or open with master key.
Present a lot of home security producers take to be equipped with the way of private key usually in order to solve an above-mentioned difficult problem, RFID(Radio Frequency Identification private key is equipped with, also known as radio frequency identification) passive chip, a card reading module is had in lock core, when card reading module detects the information of RFID on the key, after being verified, mechanical lock just can be opened.But there is easily loss, transreplication, the possibility forgotten easy to store in this method.Although be different from traditional method for unlocking, if private key drops in others' hand, the built-in RFID authentication function of security device just performs practically no function, and therefore still there is leak at secure context; Just in case main control board lost efficacy, RFID authentication function also can lose efficacy, and so also there will be the problem that cannot unblank.
Summary of the invention
In order to solve prior art Problems existing, the invention provides a kind of security device of intelligent antitheft mechanical lock, it is more intelligent, and security performance is higher, both solve traditional method for unlocking Problems existing, it also avoid the problem that security device is opened easily under user not Awareness status.
The technical solution used in the present invention is as follows:
A kind of security device of intelligent antitheft mechanical lock, comprise a body, mechanical lock and intelligent guard device, described mechanical lock is located on a body, and mechanical lock is sheltered from by intelligent guard device, the control circuit module also comprising central processing unit and be electrically connected with central processing unit, described central processing unit receives external input signal, and control by control circuit module the keying that power on/off realizes intelligent guard device, realize electromagnet and the intelligent guard of adhesive when described intelligent guard device includes energising.
In the present invention, security device is provided with electromagnet and intelligent guard in mechanical lock place correspondence, intelligent guard is held by electromagnet when equipment normally works thus stops mechanical lock key hole, open baffle plate to need to be controlled to open by external input signal, Migrant women effectively can be avoided like this to open baffle plate by simple tool key thus open mechanical lock.Particularly, central processing unit receives external input signal, after central processing unit carries out Treatment Analysis to this external input signal, makes control circuit module control energising to realize electromagnetic actuation intelligent guard or power-off makes intelligent guard open.This mode greatly reduces the risk depending merely on extra key operated existence, substantially increases the security performance of security device, more intelligent.
In addition, in the present invention, security device also has various emergency measure, and wherein when central processing unit cisco unity malfunction, control circuit module will carry out power operation to electromagnet, and intelligent guard can be opened.
Preferably, described central processing unit includes the heartbeat sending module for transmitting control signal, described control signal is heartbeat pulse signal, described heartbeat sending module sends heartbeat pulse signal to control circuit module, control circuit module carries out power on/off operation by the feedback of heartbeat pulse signal to electromagnet, thus controls intelligent guard keying.
In the present invention, central processing unit mainly adopts the mode of Signal transmissions to control control circuit module, this signal transmission form of preferred employing heartbeat pulse signal, but it is a kind of to be not limited to this, other signal transmission form is also that the present invention is contained, and controls trigger action mainly for making control circuit module by signal.Particularly, under normal circumstances, heartbeat sending module in central processing unit can continue or certain hour section sends heartbeat pulse signal to control circuit module, and control circuit module receives signal and can continue to keep, to electromagnet energising, making its adhesive intelligent guard block mechanical lock key hole; If heartbeat sending module does not continue or does not send heartbeat pulse signal to control circuit module in official hour section, then control circuit module carries out power-off to electromagnet, intelligent guard can be opened, and whether the heartbeat sending module of central processing unit send heartbeat pulse signal by external input signal and its itself affect.
Preferably, this security device also comprises the terminal input module be electrically connected with central processing unit, described terminal input module comprises fingerprint instrument module, code keypad module and RFID identification module, and described external input signal is produced by the fingerprint instrument module of terminal input module or produced for essential option and other input module combine with fingerprint instrument module.
In the present invention, terminal input module can as wherein a kind of mode of opening intelligent guard, there is the security performance higher than prior art, wherein RFID identification module is arranged on a body, RFID private key with prior art is different, it needs to go to identify with identity card or other ic cards, but it will open intelligent guard based on fingerprint instrument module, fingerprint instrument module is opened separately or is used together in conjunction with other input module and just can open baffle plate, such benefit is: finger print information is the identifying information that each user uniquely has, others' basic replication is not, so just can worry that the card used as identified in RFID identification module or key fall into this unsafe conditions in lawless person's hand and occur.
Preferably, described external input signal inputs detection module by periphery and produces, described periphery input detection module is electrically connected with central processing unit, and whether peripheral input detection module can all normally work for sense terminals input module, and feeds back to central processing unit.
