Example Embodiment

[0018] Example 1:

[0019] Intelligent access control system, including microprocessor, and level conversion chip A, level conversion chip B, fingerprint sensor circuit, voice circuit, drive circuit, clock chip, camera, GPRS module, matrix keyboard connected to the microprocessor , Display, level conversion chip A is connected with the door sensor circuit, level conversion chip B is connected with the vibration sensor circuit, the fingerprint sensor circuit is installed on the outer surface of the matrix keyboard keys, the drive circuit is connected with the control circuit, GPRS The module is connected with the remote receiving device.

[0020] In this embodiment, under normal circumstances, both the level conversion chip A and the level conversion chip B input a low level into the microprocessor. The vibration sensing circuit is installed in a hidden place on the entrance door. When it detects vibration on the door, the level conversion chip A inputs a high level into the microp...

Abstract

The invention discloses an intelligent entrance guard system which comprises a microprocessor, as well as a level switch chip A, a level switch chip B, a fingerprint sensing circuit, a speech circuit, a drive circuit, a clock chip, a camera, a GPRS (general packet radio service) module, a matrix keyboard and a display, which are connected with the microprocessor respectively. The level switch chip A is connected with a door magneto-sensing circuit, the level switch chip B is connected with a vibration sensing circuit, the fingerprint sensing circuit is mounted on the outer surface of a key on the matrix keyboard, the drive circuit is connected with a control circuit, and the GPRS module is connected with a remote receiving device. By mounting the fingerprint sensing circuit on the outer surface of the key on the matrix keyboard, the fingerprint sensing circuit can be hidden to greatly improve the security of the intelligent entrance guard system; through the combination of a coded lock and fingerprint recognition, a door can be opened only under the condition that both the code lock and a fingerprint are right, so that trespass can be prevented effectively.

Description

Technical field [0001] The invention relates to the field of security, and specifically refers to an intelligent access control system. Background technique [0002] With the improvement of material living standards, people have higher and higher requirements for access control systems. At present, the more advanced access control systems on the market usually use electronic locks or fingerprint locks. The electronic lock controls the operation of the circuit or chip through the password input, thereby controlling the closing of the mechanical switch, and completing the unlocking and locking tasks. Fingerprint lock is a kind of smart lock which uses human fingerprint as identification carrier and means. Although both have their own advantages, there are still corresponding shortcomings. When entering the password for the electronic lock, if there is someone next to it or it is not completely covered, the password is easily stolen. The fingerprint lock has a large scanning sur...
