After timing is long, then motor-drive circuit is sent by the control signal being currently received, make motor-drive circuit in specified duration
Interior uncontrolled signal control, opens by mistake and opens so as to be effectively prevented intelligent door lock by strong electromagnetic signal.
In order to better understand the above technical scheme, below by attached drawing and specific embodiment to technical solution of the present invention
It is described in detail, it should be understood that the specific features in the embodiment of the present invention and embodiment are to the detailed of technical solution of the present invention
Thin explanation, rather than the restriction to technical solution of the present invention, in the absence of conflict, the embodiment of the present invention and embodiment
In technical characteristic can be combined with each other.
Referring to FIG. 1, the embodiment of the present invention provides a kind of method of anti-strong electromagnetic, it is applied to intelligent door lock, the party
The treatment process of method is as follows.
Step 101: it is pre- whether the voltage value that detection is sent to the control signal of the motor-drive circuit of intelligent door lock is greater than
If threshold value；Wherein, the motor that control signal is used to control in motor-drive circuit driving intelligent door lock opens intelligent door lock.
Step 102: if it has, then control signal carries out delay process will currently receive after delay reaches specified duration
To control signal be sent to motor-drive circuit, make motor-drive circuit uncontrolled signal control in specified duration.
After intelligent door lock is by strong electromagnetic, the waveform of the DC power supply output of intelligent door lock refers to Fig. 2.From
In Fig. 2 as can be seen that when by strong electromagnetic, the voltage magnitude of power supply signal can be multiplied, and be with 5V DC power supply
Example, when it is by strong electromagnetic signal interference, its voltage peak-to-peak value can reach 15V or more.It has been investigated that intelligence at this moment
Main control chip and signal in energy door lock also will receive interference, and then reset main control chip, so as to cause control intelligence
The control signal that door lock is opened opens by mistake intelligent door lock and is opened by false triggering.
The signal exported after resetting in order to avoid main control chip is turned on intelligent door lock, can be to being sent to intelligence
The voltage value of the control signal of the motor-drive circuit of door lock is detected, and is preset when the voltage value for detecting control signal is greater than
When threshold value, the control signal received is started to be delayed by motor-drive circuit, until being delayed to after specified duration, just will
The control signal being currently received is sent to motor-drive circuit, makes motor-drive circuit uncontrolled signal in specified duration
Control.
Wherein, preset threshold is the supply voltage value for controlling chip.For example, the supply voltage value of control chip is 5V, then
Preset threshold is 5V, and the supply voltage value for controlling chip is that then preset threshold is 3.3V to 3.3V, or the power supply of control chip is electric
Pressure value is that then preset threshold is 1.8V to 1.8V.
Specified duration is specially to be not less than the duration of the reset signal of control chip of output control signal.For example, control
The when a length of 100ms of the reset signal output of chip A, then a length of 100ms when specifying.
Preferably, the preferred value of preset duration is 200ms.On the one hand the value of preset duration is set as 200ms not will use
Time delay is significantly perceived at family in use, on the other hand can well adapt to the reset duration of most of control chips again.
It can make to control chip of short duration reset when interfering intelligent door lock due to strong electromagnetic signal interference, and export control
Intelligent door lock open mistake control signal, the voltage value of the control signal of the mistake can increase suddenly and duration compared with
It is short, so starting the control to receiving when the voltage value for controlling signal for determining that control chip is sent is more than preset threshold
Signal carries out delay process, and after delay is to specified duration, then that the control signal being currently received is sent to motor driven is electric
Road, effectively can evade falling the control signal for the mistake for exporting main control chip because of strong electromagnetic, and then make intelligence
Door lock has the performance of preferable anti-strong electromagnetic, avoids being opened by mistake opening, and improves safety.
Further, when intelligent door lock, which is provided at least two control chips, to be verified to user identity, control letter
Number for the signal that is obtained after the progress of control signal corresponding binary data or operation at least two control chips outputs；Its
In, after each control chip passes through subscriber authentication using different auth methods, the control signal of corresponding output
Motor-drive circuit can be controlled.
For example, intelligent door lock can touch screen input password, fingerprint, recognition of face, by way of iris recognition to
Family identity is verified, and authentication is carried out using control chip A for the mode of touch screen input password, for referring to
Line, recognition of face, iris recognition mode using control chip B carry out authentication.
If user inputs the mode opening door lock of password with touch screen, when password exports, correct control chip A is determining to be used
The authentication at family has passed through and has exported control signal A (being assumed to be high level signal), later will control signal A and control chip
The control signal B (being assumed to be low level signal) of B output is carried out or operation, obtains new control signal (for high level signal),
Whether the voltage value for then detecting new control signal again is greater than preset threshold 3.3V, if yes starts to carry out delay process, when
After delay reaches 200ms, the control signal being currently received still is high level signal, then explanation is correctly control signal, this
When by the control signal being currently received be sent to motor-drive circuit open intelligent door lock.
If having illegal invasion person that " small black box " is used to carry out strong electromagnetic to the intelligent door lock of user, due to intelligent door lock
After interference by strong electromagnetic signal, control chip A, B in any one be reset, the control signal A of output error (assuming that
Control chip A and export high level signal), control signal A and B are carried out later or operation obtains new control signal later, so
Whether the voltage value for detecting new control signal again afterwards is greater than preset threshold 3.3V, if yes starts to carry out delay process, when prolonging
When reach 200ms after, the control signal being currently received still is low level signal, then illustrates that intelligent door lock receives forceful electric power magnetic signal
Interference, due to mistake control signal disappeared after 200ms, i.e. control signal after 200ms has restored normally, so
The current control signal that motor-drive circuit is sent to after 200ms is normal control signal, so that electricity can be prevented effectively
Drive circuit receives the control signal of the mistake generated by strong electromagnetic, and can allow normal control signal when specified
Motor-drive circuit is sent to after length.
It should be noted that the control motor-drive circuit that control chip is sent opens the correct control letter of intelligent door lock
Number duration be greater than specified duration.

For the current-limiting resistance of 10k Ω, U1 is a delay chip, and whether the voltage value that can detecte the signal received is greater than default threshold
Value, and start to be delayed when being greater than preset threshold, the when a length of specified duration of delay.
When delay chip U1 detects the voltage value of control signal IN greater than preset threshold (such as 1.8V), start to be prolonged
When, after delay duration reaches specified duration (such as 200ms), current control signal IN is sent to as output signal OUT
Motor-drive circuit 303, if current control signal IN is the control letter for controlling motor-drive circuit 303 and opening intelligent door lock
Number, then intelligent door lock is opened, if current control signal IN is the control for controlling motor-drive circuit 303 and being not turned on intelligent door lock
Signal is then not turned on intelligent door lock.
For example, the voltage value of control signal IN is prominent when having " small black box " to generate strong electromagnetic signal interference intelligent door lock
It so increases, the interference signal in duration 80ms, this 80ms can be high-frequency signal as shown in Figure 2, delay circuit 302
After detecting that the voltage value of control signal IN increases, start to be delayed, it, will after delay duration reaches specified duration 200ms
Current control signal IN is sent to motor-drive circuit 303, and the voltage value of control signal IN current at this time has been restored to just
Constant value (low voltage value).
Since the unlocking verification mode of present intelligent door lock is varied, for example, can by way of inputting password,
After password authentification success, the pin level of output control signal IN can be set to high level by the control chip of administrator password input；
Control chip can also be transmitted verification result to by serial ports after fingerprint authentication success, controlled by way of inputting fingerprint
The pin level processed of output control signal IN is set to high level again by coremaking piece；Can also use other verification modes, as magnetic card,
Bluetooth, iris, recognition of face etc. control chip output control signal after being proved to be successful；It can be in the same intelligent door lock
To a kind of above-mentioned verification mode, a variety of verification modes also can be used.When using a variety of verification modes, if different verifyings
Mode is verified respectively with different control chips, then intelligent door lock further include:
Or the input terminal of door 305 or door 305 is connect at least two control chips in control circuit 301 or door 305
Output end connect with the input terminal of delay circuit 302, for at least two control chips output control signal it is corresponding
Binary data carries out or operation；Wherein, each control chip is logical to subscriber authentication using different auth methods
Later, the control signal of corresponding output can control the corresponding signal of result of the motor-drive circuit 303 or operation as electricity
The control signal that drive circuit 303 receives.
Fig. 5, touch circuit and cryptochannel is referred to output a control signal to or door 305 after verifying password passes through, or
The control signal (being assumed to be high level) and control circuit 301 of control chip A3011 output in 305 pairs of control circuits 301 of door
