Detailed ways

As shown in Figure 1, the mobile phone NFC text message alarm video surveillance access control system includes an identification system, a text message alarm system, an intelligent monitoring system and a network communication system. Module and single-chip microcomputer, intelligent monitoring system includes wireless and camera, network communication system includes single-chip microcomputer and ethernet card; Described identification system, SMS alarm system and network communication system share a single-chip microcomputer, and this single-chip microcomputer connects GPRS module, ethernet card and wireless module respectively , the camera is connected to the single-chip microcomputer, the NFC mobile phone realizes information transmission through the NFC read-write module and the single-chip microcomputer, the GPRS module sends the received information to the user and the alarm center through wireless communication, and the Ethernet card transmits the monitoring information processed by the single-chip microcomputer to the network.

The single-chip microcomputer is also connected to the liquid crystal display to control it to display the account information and authority of the NFC mobile phone that opens the door.

The SMS alarm system can also receive and send information through Bluetooth mode.

The serial number of the NFC mobile phone is different. Only the NFC mobile phone with the specified serial number can recognize and open the access control system.

The MCU is Arduino Uno R3 MCU.

The model of the Ethernet card is ENC28J60.

The wireless model is NRF2401.

When approaching the NFC read-write module, the NFC mobile phone and the NFC read-write module perform data transfer, and at the same time, the single-chip microcomputer controls the liquid crystal display to display the relevant account information of the mobile device and whether it has passed the audit. The network card transmits the information processed by the single-chip microcomputer to the network, and at the same time, the GPRS module sends the NFC mobile phone information to the user in the form of MMS.

The user can modify the account number and password of the NFC mobile phone through the network, which improves the security of the system.

An NFC mobile phone must register an account and password in advance, and an NFC mobile phone has only one account and password.

When the NFC mobile phone cannot be used, the user can log in to his account through the network, modify the account number and password, and then register a new account number and password.

The following is a detailed description of the entire access control system combined with specific examples:

Firstly, use the initialization program to clear the information stored inside the single-chip microcomputer, so that the internal parameters of the single-chip microcomputer are in the default state, and everything is ready. When the user holds the NFC mobile phone close to the access control system to open the door, the NFC read-write module generates a magnetic field to sense the NFC mobile phone, reads the information in the NFC mobile phone and uploads it to the single-chip microcomputer for information processing. There are two types of results after processing, one is authorized and the other is not authorized.

If the single-chip microcomputer grants authorization, that is, the corresponding account password is queried in the access control authorization ID, the information in the NFC mobile phone will be read, and the single-chip microcomputer controls the liquid crystal display to display the relevant account information of the mobile device and activate the electronic lock.

If Arduino does not grant authorization, that is, the corresponding account password cannot be found in the access control authorization ID, the information in the NFC mobile phone will also be read and saved, but no measures will be taken, and the electronic lock will not be activated.

Further, in order to solve the problem that the access control is maliciously swiped multiple times, the system is set to activate the monitoring device whenever the same account is swiped three times. Monitoring device 1: GPRS module, the system will record the information of this account and send a short message through the GPRS module To the user, notify that someone opened the door illegally.

Further, start the monitoring device 2: the video monitoring module. When three errors occur, the system sends an instruction to start the camera head and the steering gear, take pictures of the intruder in a rotating manner, record the time and save it, and then start the GPRS module again. Images and time travel to users.

Further, after the system records the malicious account, it will be added to the blacklist preset by the system. In the process of unlocking later, if any account in the blacklist is found, the GPRS module and video surveillance will be started directly instead of three times of error reminders. The module enters a comprehensive anti-theft state.

Further, in order to solve the problem of losing the NFC mobile phone device, the user can log in to the server to cancel the permission or the user can call the customer service number to manually cancel the permission. After the permission is canceled successfully, preferably, the user is notified of the successful permission cancellation by email.

Further, in order to avoid malicious destruction by those who pick up the NFC mobile phone, the user can also authorize the NFC mobile phone to remotely locate the mobile phone and initialize the mobile phone to prevent leakage of the mobile phone.

Furthermore, in order to solve the problem of unlocking by multiple people in a family, NFC mobile phones are not limited to any electronic devices such as mobile phones, tablet computers, and watches embedded with NFC chips, but these electronic devices have NFC chips that are divided into main cards and secondary cards.

Furthermore, the main card can grant and remove the authority of the secondary card, but the secondary card cannot interfere with the primary card. Specifically: the primary card can enter and exit all the doors of the house, but the holder of the secondary card may only be able to open the door of the home, but cannot open the door of the home. A specific door, and if you want to open other doors in your home, you need to grant permission from the main card holder.

Furthermore, the main card holder can limit the use time of the auxiliary card. Specifically, the main card restricts the auxiliary card to be valid from 9:00 to 16:00 every day. Then the secondary card holder can open the door during this period of time, after this period of time, the secondary card will be invalid, and if you want to obtain permission again, you need to obtain the consent of the primary card holder.

Further, in order to solve the problem that the secondary card obtains authority outside the valid time, the secondary card holder only needs to swipe the card in the access control sensing area, then the NFC read-write module receives the information from the NFC mobile phone to open the door, and then sends it to the primary card holder. For example, through email or text messages, wait for the main card holder to approve through the NFC mobile phone, that is, agree or disagree with the corresponding operation for processing, and if the main card holder passes the approval, then feedback to the corresponding NFC mobile phone Information granting permissions, such as sending to NFC mobile phones by email or SMS.

Further, if the main card holder fails to pass the approval, correspondingly feed back the information that there is no such permission to the NFC mobile phone.

What is described in the above specification is only the preferred implementation of the present invention, and various illustrations do not limit the essence of the present invention. Those of ordinary skill in the art can modify or modify the previously described specific implementation after reading the specification. Deformation, without departing from the novelty and principle, some improvements and modifications can also be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
