Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As shown in fig. 1, a method for implementing anti-eavesdropping and video recording by using a hardware circuit design according to the present invention is shown, which comprises the following steps:
s100, manual adjustment: pressing or shifting an entity key/switch on the intelligent machine according to the requirement;
s200, signal path control: sending a control signal to the analog switch to control the state of the input end of the analog switch;
s300, circuit on/off: and switching on/off the camera and the microphone according to the state of the input end of the analog switch so as to switch between a normal mode and a safe mode.
Specifically, in step S100, during manual adjustment, the physical keys/switches on the smart machine are pressed or toggled as needed. As shown in fig. 2, when the switch is pressed, the pin 2 of the electromagnetic switch 1 is communicated with the pin 3, no voltage exists on the output end, when the switch is bounced, the power supply is connected with the output end, and the voltage on the output end is the voltage value of the power supply; as shown in fig. 3, the power switch is turned on, and is connected to the D flip-flop 2, the D flip-flop 2 is an edge flip-flop,
to clear the input port, D is the input port, GND is the ground terminal, Q is the output terminal,
in order to invert the output end, the output end is inverted,
is a preset input terminal, Vcc is a power supply terminal, a CLK pin is a clock input terminal, and the CLK pin receives a timing signal when a predetermined transition (positive transition or negative transition) of a clock pulse CP comesData is input. When CP 1 and CP 0 and CP unconventional jump come, flip-flop does not receive data, used for receiving and memorizing the signal, when the key is pressed, produce the edge signal, D flip-flop 2 memorizes the edge signal and changes into the steady level signal, control the analog switch to switch.
In step S200, in the signal path control, a control signal is sent to the analog switch to control the state of the input terminal of the analog switch, and the output terminal of the analog switch sends a level signal to the analog switch. When the gating end is in the gating state, the state of the output end depends on the state of the person input end; when the gating end is in a blocking state, the output end is in a high-impedance state no matter how the level of the people input end is, namely, the circuit is disconnected, and the analog switch mainly plays a role in switching on or switching off signals in the electronic equipment.
IN step S300, during the circuit power on/off, the camera and the microphone are powered on/off according to the state of the input end of the analog switch, so as to switch between the normal mode and the safe mode, as shown IN fig. 4 and 5, the model of the first analog switch 3 and the second analog switch 4 is SGM3157YC6, wherein the NO port is a normally open end, the NC port is a normally closed end, the GND port is a ground end, the V + port is a power end, the IN port is a control signal input end, the COM port is a communication end, the IN port is connected to a level signal of the switch control signal, when the level signal is high, the circuit LOGIC 1 is on, the NO end is on, the NC end is off, that is, when the microphone power supply signal is disconnected from the reset signal of the camera, IN the safe mode, when the level signal is low, the circuit LOGIC NC is 0, the NO end is off, the end is on, that is, the power supply signal of the microphone is connected with the reset signal of the camera at this time, and the camera is in a normal use mode.
In this embodiment, in step S100, in the manual adjustment, the physical switch is connected to a control circuit, and the physical switch is an electromagnetic switch 1.
