Embodiment Construction

[0030] Such as figure 1 As shown, the NFC mobile phone dynamic password access control system includes a GSM module, a user module and a liquid crystal display. The user module is connected to the GSM module through wireless communication, and can receive notification messages sent by the GSM module, and can also issue instructions to the GSM module. It is characterized in that: the access control system also includes an NFC mobile phone, an Arduino module, an NFC card reader module, a matrix keyboard and an alarm center; Connect the LCD display, connect the matrix keyboard to the Arduino module, and the NFC mobile phone realizes information transmission through the NFC card reader module and the Arduino module.

[0031] A dynamic password library composed of numbers and letters is formed by writing in Arduino language. Every time the user module swipes the card to open the door, the system will randomly generate a new password and write it into the user module to realize dyna...

Abstract

NFC mobile phone dynamic password access control system, including GSM module, user module and liquid crystal display, NFC mobile phone, Arduino module, NFC card reader module, matrix keyboard and alarm center, described GSM module, Arduino module and NFC card reader module are connected successively, The GSM module is also connected to the alarm center, the Arduino module is connected to the LCD display, the matrix keyboard is connected to the Arduino module, and the NFC mobile phone realizes information transmission through the NFC card reader module and the Arduino module. Beneficial effects of the present invention: the present invention can realize the function of modifying the dynamic password each time the NFC mobile phone swipes the card, and there is no recurring password, which improves the security of the access control system.

Description

technical field [0001] The invention relates to the field of home security, in particular to an NFC mobile phone dynamic password access control system and a control method thereof. Background technique [0002] Safety is very important in our life. Without safety, life will become without happiness and happiness. It is related to whether everyone's life and property can be guaranteed. The fruits of the past, everything you have suddenly becomes nothing. Therefore, safety is a prerequisite for a better life, and safety marks the quality of life. [0003] Home security system refers to a comprehensive system that provides residential intrusion alarm system services through various alarm detectors, alarm hosts, cameras, card readers, access controllers, alarm centers and other security equipment. Contains three subsystems: CCTV subsystem, access control subsystem and intrusion alarm subsystem. A good home security system needs a comprehensive alarm center. [0004] The fun...
