Description

A kind of passive electronic lock
Technical field
The present invention relates to a kind of lockset, concrete, relate to a kind of passive electronic lock system.
Background technology
Along with socioeconomic development, industry-by-industry has occurred that a lot of valuables and equipment need to be placed in safety cabinet; Improving constantly along with people's living standard simultaneously, individual privacy and property safety also more and more come into one's own, and personal proof box is also more and more universal.
But, the safety cabinet that existing employing mechanical lock opens and closes and proof box are easily by people's technical opening, security is low, and the safety cabinet that existing employing active electronic lock opens and closes will be installed power supply with proof box or be connected with power supply, once power supply can not provide electric energy, safety cabinet and proof box cannot be opened, very inconvenient.
Summary of the invention
For overcoming the shortcoming of the lockset of prior art, the invention provides a kind of passive electronic lock.
Passive electronic lock system of the present invention, comprises intelligent terminal and passive electronic lock, described intelligent terminal and passive electronic lock wireless near field communication.
As a kind of preferred embodiment of the present invention, described passive electronic lock comprises the NFC objective chip, coupled boost circuit, rectification circuit, tank circuit and the mechanical lock that connect successively.
As a kind of preferred embodiment of the present invention, described intelligent terminal comprises NFC and initiates chip.
As a kind of preferred embodiment of the present invention, described intelligent terminal is smart mobile phone or PAD.
Compared with prior art, passive electronic of the present invention is locked the intelligent terminal typing password of system and password is sent to NFC objective chip, the standard cipher stored in typing password and NFC objective chip compares, and only has and just can complete unlocking action when typing password is identical with standard cipher; In addition, the electric energy in intelligent terminal by near field induction, coupled boost, rectification, releases energy after energy storage step, and then controls mechanical lock unlatching, the drawback cannot opened when avoiding existing electronic lock power-off by passive electronic lock system of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of passive electronic of the present utility model lock system;
Fig. 2 is the passive electronic lock system work process schematic diagram of utility model.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
See Fig. 1, wherein dotted line represents unlimited connection, and solid line represents electrical connection.
Passive electronic lock system of the present invention comprises intelligent terminal 1 and passive electronic lock 2.Intelligent terminal 1 comprises NFC and initiates chip 11, it is provided with the unblock APP locking system support with passive electronic of the present invention, and intelligent terminal 1 can be the common intelligent terminal such as smart mobile phone, notebook computer or PAD; Passive electronic lock 2 comprises the NFC objective chip 21, coupled boost circuit 22, rectification circuit 23, tank circuit 24 mechanical lock 25 that are electrically connected successively.
Intelligent terminal 1 and passive electronic lock 2 initiate chip 11 by NFC and NFC objective chip 21 carries out near-field communication and energy transferring, electric energy on intelligent terminal 1 is converted to the electric energy on passive electronic lock 2, for also can open the lock on it when passive electronic lock 2 is not connected with any power-supply unit; Energy density due to near-field communication transmission is less and mechanical lock 25 opens the larger energy of needs, therefore passive electronic lock be provided with coupled boost circuit 22, rectification circuit 23, tank circuit 24 for the energy from intelligent terminal 1 received its boost, rectification and energy storage process, when the energy stored in tank circuit 24 is enough to open mechanical lock 25, tank circuit 24 releases energy, and mechanical lock 25 is opened.
With reference to figure 2, it is the workflow diagram of passive electronic lock system of the present invention when intelligent terminal 1 is mobile phone.The job step of passive electronic lock of the present invention is as follows:
S1: the unblock APP typing unlocking pin of user first on mobile phone, locks mobile phone near passive electronic simultaneously;
S2: the NFC objective chip 21 that the NFC on mobile phone initiates on chip 11 and electronic lock sets up near-field communication;
S3: the NFC on mobile phone initiates chip 11 sends unlocking pin from user's typing to the NFC objective chip 21 on electronic lock;
S4: the NFC objective chip 21 of passive electronic lock receives mobile phone NFC and initiates the password sent of chip 11 and judge that whether this password is correct, if judged result is no, then releasing process terminates, and if the determination result is YES, then enters S5 step;
S5: mobile phone transmits energy by near-field communication to passive electronic lock, because the unlatching of mechanical lock needs larger energy, therefore this step may continue even tens seconds in a few second;
S6: the energy that passive electronic lock is transmitted by self coupled boost circuit 22, rectification circuit 23, the tank circuit 24 pairs of mobile phones boosts, rectification and stores processor;
S7: passive electronic lock judges whether the energy that tank circuit 24 stores can open mechanical lock 25, if judged result is no, then enters S5 step, if the determination result is YES, then enters S8 step;
S8: tank circuit releases energy, mechanical lock is opened;
S9: releasing process terminates.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is only limited to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
