And system have many advantages, such as it is small in size, easy for installation, be convenient for practical application.
Detailed description of the invention
Fig. 1 is the working principle block diagram of the utility model.
Fig. 2 is utility model works flow chart.
Fig. 3 is the utility model driving circuit figure.
Specific embodiment
As shown in Figure 1, 2, 3, a kind of High reliable intelligent access control system based on fingerprint recognition, includes main control chip 1
And matrix keyboard 1, matrix keyboard 24, fingerprint collecting and the processing module 2, liquid crystal display being connect with main control chip 1
One 6, liquid crystal display 27, driving circuit 8, warning circuit 5 and serial ports turn WIFI module 10, the driving circuit 8 it is defeated
Outlet is connected with lock body motor 9, and the serial ports turns WIFI module 10 and successively connect with wireless router 11, light Modem12, institute
The light Modem12 stated is connected with mobile phone terminal 14 by Ethernet 13.
The model STC89C52RC of the main control chip 1.
It is super low-power consumption conversion module USR-WIFI232 that the serial ports, which turns WIFI module 10,.
The driving circuit 8 is made of metal-oxide-semiconductor, photoelectrical coupler and relay.
The fingerprint collecting and processing module 2 use the advanced capacitive fingerprint module of TFS-M74.
The main control chip 1 uses STC89C52RC single-chip microcontroller, ensure that system cost performance with higher and anti-interference
Performance, the main control chip receive input signal by matrix keyboard, fingerprint collecting and processing module.These input signals are through master control
After chip is according to certain algorithm process, main control chip can issue control command driving unlocking operation or alarm operation.In system
Under Setting pattern, as long as correctly entering administrator's password, user can be close by the setting of matrix keyboard 1 unlocking mode, modification
Code increases user fingerprints, deletes a series of system setup operations such as user fingerprints.Under unlocking mode, when main control chip receives
To after input unlocking data, the data stored in unlocking data and main control chip can be compared, if the two can match
Unlocking operation is then completed, requires to re-enter unlocking data if it cannot match, and such as cannot be in preset input data
Then system enters locking state for the matching of completion data in the range of limit, while starting warning circuit and issuing alarm, and then
Serial ports turns WIFI module also and will start by Ethernet to notify current access control system illegal invasion information to user.
The fingerprint collecting is deposited with the completion of processing module 2 fingerprint collecting, image procossing, feature extraction, template generation, template
The functions such as storage, fingerprint comparison.
The keyboard is matrix keyboard, and system is provided with 2 matrix keyboards, is respectively arranged in Men Nei and outdoors.Door
Interior keyboard has been used for some settings operation of paired systems, and keyboard outdoors is served only for input unlocking information, this is conducive to mention
The safety of high system.
The warning circuit 5 is made of field-effect tube and buzzer.Field-effect tube is voltage control device, quiescent operation feelings
Power consumption is extremely low under condition.Buzzer selects passive buzzer, as long as by the frequency for changing input signal, passive buzzer
Different alarm sounds is issued, realizes warning function when access control system illegal invasion.
The liquid crystal display 1, liquid crystal display 27 are used for the status information of display system operation, improve system
The performance of system human-computer interaction.
Since the output signal of main control chip 1 can not directly drive the work of lock body motor, need in main control chip and lock body
Driving circuit is set between motor, and the driving circuit is worked using the switching function control lock body motor of its relay.
Fig. 2 is the software systems main program flow chart of the utility model.Complete each function mould of system first in flow charts
The initialization operation of block；Then judge whether two matrix keyboards have by key pressing.Keyboard one in this way has key pressing, needs input pipe
Reason person's password could complete some settings operation of system, such as increase user fingerprints, Modify password operation；Keyboard two in this way has
Key pressing, system can ask whether it is unlocking key pressing first, then enter unlocking operation process in this way, can ask if being not system
Ask whether be energency-unlocking key pressing, then enter energency-unlocking process in this way, otherwise system, which executes, returns to operation.
