Description
Technical field
The invention belongs to internet areas, and in particular to a kind of burglary-resisting system of intelligent door lock by electromagnetic interference.
Background technique
It is to come the case where unlocking using Tesla coil in transmission on Internet that electromagnetic interference, which is unlocked, so that intelligent door
Lock user concerns one after another, and this electromagnetic interference unlocking mode carries out the circuit of intelligent door lock using strong voltage and heavy current
Impact causes its system reboot or chip to crash, and part intelligent door lock is set as crashing or restarting rear auto-unlocking.But
Such unlocking mode still brings hidden danger to the safety of intelligent door lock, and user goes out after locking a door, and can not learn intelligent door lock
Whether unlocked by user using electromagnetic pulse interference.The intelligent door lock that monitoring or alarm can be played therefore, it is necessary to one kind is anti-
The burglary-resisting system of electromagnetic pulse interference.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of intelligent door lock burglary-resisting system, passes through pulse detector pair
Electromagnetic pulse interference is acquired, and determines whether electromagnetic interference pulses reach alert if by comparator, is then controlled by MCU
System alarm and upload information to mobile terminal；This system can effectively prevent bring property after unlocking using electromagnetic pulse interference
The case where loss, occurs.
For this purpose, the present invention provides a kind of intelligent door lock burglary-resisting system, including pulse detector, MCU, comparator, power supply,
Alarm and mobile terminal；The pulse detector is electrically connected with comparator, and the comparator is electrically connected with MCU, the MCU with
Alarm is connected with mobile terminal, and the power supply is pulse detector, MCU, alarm provide power supply.
Electromagnetic pulse interference signal is detected by pulse detector, predominantly detects the frequency of electromagnetic pulse interference signal
Rate and interference duration, are then compared electromagnetic pulse interference signal with given threshold by comparator, and with this
Determine whether to reach the condition for reporting MCU, by information reporting to MCU if reaching, alarmed by MCU to control alarm,
Meanwhile mobile terminal is sent so that user knows that for door lock by electromagnetic pulse interference, there are doubtful in family by warning message
Like illegal unlock situation.
For the pulse frequency threshold value that the comparator is set as 500HZ, burst length threshold value is 100ms, works as pulse detector
It detects electromagnetic pulse signal and the electromagnetic pulse frequency for relatively obtaining external generation through comparator is more than 500HZ and pulse persistance
Time is more than 100ms, then sends information to MCU, controls alarm equipment alarm by MCU and by warning message and pulse detector institute
The data detected are sent to mobile terminal.
Show that electromagnetic pulse is greater than 500HZ when acquiring by pulse detector and being compared by comparator, and into
Find that the electromagnetic pulse duration is greater than 100ms in the detection process of one step, then doubtful someone is using electromagnetic pulse interference intelligence
The circuit of door lock carries out illegal unlock, at this point, after reporting information, MCU to receive the information that comparator reports by comparator, starting
Alarm is alarmed, while by illegal unlock information reporting to mobile terminal.
In the present solution, the electromagnetic pulse interference frequency threshold and electromagnetic interference pulses duration threshold of design are 100ms
The reason of be: under normal circumstances, intelligent door lock itself circuit can generate the punching of interference electromagnetism second, frequency in 300HZ or so,
And the duration is less than 50ms under normal circumstances, and it is dry to need to reach the electromagnetic pulse that electromagnetic pulse interference is unlocked
The frequency for disturbing signal is typically larger than 500HZ, and the duration can reach 500ms, therefore the frequency threshold designed in this programme
For 500HZ, duration threshold 100ms, the threshold value be can be adjusted according to the actual situation.
The comparator uses LM393 twin voltage comparator, and since the consumption electric current of LM393 is small, input offset voltage is small,
And common-mode input voltage range is wide, output can be compatible with TTL, DTL, MOS, CMOS etc., thus select LM393 can guarantee be
System comparing function stable operation.
It is equipped with wireless communication module between the MCU and mobile terminal, leads to for realizing MCU and the remote of mobile terminal
Letter, when indoors or door of leaving home is not far, can be completed communication connection using bluetooth, if distance is farther out, can realize MCU by GSM
With the communication of mobile terminal, and MCU typically is provided with communications pins and interface, as long as therefore pin be adapted to i.e. with wireless communication module
It can.In the present solution, only with gsm wireless communication module.
The MCU is also connected with reseting module, when the electromagnetic pulse information collected that comparator reports reaches alarm bar
Part then starts reseting module and resets to the system of intelligent door lock, forbids this time unlocking.In order to prevent impulse disturbances unlock at
Function is arranged reseting module and is protected, when reach report required alert if after, MCU control reseting module is actuated for
It resets, alarm prevents property loss in family simultaneously to prevent this unlocking.
The beneficial effects of the present invention are: a kind of intelligent door lock burglary-resisting system of the invention, can to electromagnetic pulse interference into
Row effectively monitoring, and by the processing and judgement to electromagnetic pulse interference signal, it carries out real-time report and to mobile terminal and opens
Dynamic alarm is alarmed, and intelligent door lock security performance is improved.
