Description
Technical field
The present invention relates to gate controlled switch field, especially a kind of access control system based on radar induction and image recognition.
Background technique
It for the convenience of the user under conditions of night or poor available light, can also easily open the door, at gate inhibition usually all
It is provided with corridor lamp or doorway lamp, but these lamps generally use acoustic control, temperature control or the control of manual key formula.The switch of acoustic control or temperature control
Often had already turned on when people does not also reach doorway, thus its lighting time section be not since when people is in doorway position,
This results in reaching half lamp and can extinguish, and needs to be again turned on.And the switch of manual key formula needs to open and manually manually
It closes, opens behind the door if forgetting to turn off the light, will lead to the waste of the energy.
On the other hand, the thing that people take on hand sometimes is more, takes key to open the door very inconvenient.Therefore, being badly in need of one kind can
Automatic opening and closing door and the control system that illumination can be realized when opening the door.
Summary of the invention
Goal of the invention: in order to solve the above technical problems, the present invention provides a kind of door based on radar induction and image recognition
Access control system.
Technical solution: technical solution proposed by the present invention are as follows:
It is a kind of based on radar induction and image recognition access control system, comprising: radar detected module, frequency mixer, amplifier,
Delayer, start-up circuit, the first relay, the second relay, picture collection module and microprocessor；Wherein,
Radar detected module, frequency mixer, amplifier, delayer, start-up circuit successively cascade, and the output end of start-up circuit is logical
The first relay is crossed to be connected with luminous lamp switch；The output end of start-up circuit passes through the second relay and picture collection module simultaneously
It is connected, the output end of picture collection module is connected with microprocessor, and the output end of microprocessor is connected with the electronic lock of gate inhibition；
Radar detected module detection enters the echo-signal of people's reflection in search coverage, and echo-signal is successively by mixing
Enabling signal is formed after device, amplifier, delayer, and is sent to the input terminal of start-up circuit, and start-up circuit is according to enabling signal control
It makes the first relay and is attracted luminous lamp switch；Meanwhile start-up circuit triggering picture collection module acquisition enters in search coverage
The picture of people, and give to microprocessor, microprocessor opens electronic lock after identifying the personage master in picture.
Further, the radar detected module is TX982 microwave induction controller.
Further, the time delay module is 555 delayers.
Further, the delay duration of the time delay module is 2~3min.
Further, the picture collection module is high-definition camera.
The utility model has the advantages that compared with prior art, present invention has the advantage that
The present invention can identify house owner's identity by image recognition technology, realize automatic opening and closing door；And it can stand in house owner in door
Illumination is provided when mouth, ideal light is provided for system acquisition house owner's photo, increases the sensitivity and efficiency of identification.
Detailed description of the invention
Fig. 1 is the structure chart of the access control system of the present invention based on radar induction and image recognition.
Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
Fig. 1 is the structure chart of the access control system of the present invention based on radar induction and image recognition, includes: in figure
Radar detected module, frequency mixer, amplifier, delayer, start-up circuit, the first relay, the second relay, picture
Acquisition module and microprocessor；Wherein,
Radar detected module, frequency mixer, amplifier, delayer, start-up circuit successively cascade, and the output end of start-up circuit is logical
The first relay is crossed to be connected with luminous lamp switch；The output end of start-up circuit passes through the second relay and picture collection module simultaneously
It is connected, the output end of picture collection module is connected with microprocessor, and the output end of microprocessor is connected with the electronic lock of gate inhibition；
Radar detected module, to spatial emission microwave signal, forms a microwave sounding region by own transmission coil,
When someone enters the microwave sounding region, radar detected module is received by included receiving coil enters the microwave sounding area
The echo-signal of people or object reflection in domain, and it is sent to frequency mixer；
Echo-signal is mixed by frequency mixer with transmitting signal, obtains the frequency displacement between two paths of signals, and frequency shift signal is sent
To amplifier；
Amplifier is sent to time delay module after amplifying processing to frequency shift signal；
Time delay module generates enabling signal according to the frequency shift signal received and is sent to start-up circuit, and time delay module is protected
It holds output enabling signal for a period of time, may be configured as this period 1~3 minute, to leave the system enough reaction time for, with
Just the movement of subsequent take pictures identification and enabling is completed；
Start-up circuit starts the first relay according to enabling signal, is attracted lamp switch, and lamp is opened at this time.
Start-up circuit starts the second relay while starting the first relay, powers on for picture collection module；Picture is adopted
Collection module one is triggered, then shoots the photo of the people in search coverage immediately, and the photo of shooting is sent to microprocessor, micro- place
It manages device Built-in Image and identifies engine, and be previously stored with the photo of house owner in a storage module, microprocessor is by the photo of acquisition
It is compared with house owner's photo of storage, if regarding as same people, the electronic lock of microprocessor access control is opened；Otherwise,
Microprocessor does not open the electronic lock of gate inhibition.
After house owner enters house, since radar detected module can not detect the reflection signal in microwave sounding region,
Whole system can not generate enabling signal, reach back light so waiting to set aside some time and steep oneself-meeting automatic distinguishing, electronic lock can also be locked again
On, the switch of the switch of lamp and door while convenient to use without manually, being avoided that because forgetting to cause due to turning off the light in whole process
Waste of energy.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
