Automatic access control system and its implementation method based on mobile phone bluetooth communication

Abstract

The invention discloses an automatic access control system based on mobile phone bluetooth communication and a realization method thereof. The automatic access control system includes an access controller installed at the entrance and exit, a mobile phone and an access control program, and a remote management server. The access controller includes a bluetooth communication module, a data processing unit and a relay control circuit. After the user's mobile phone is installed with the access control program, it will obtain the authorization and key information provided by the management server according to the user's identity. When the user is near the Bluetooth access controller, the mobile phone communicates with the access controller through Bluetooth signals. The Bluetooth access control controller judges whether the door can be opened through the communication content. If the door can be opened, the access control controller automatically opens the door by controlling the relay, or activates the door opening switch, and the user presses the switch to control the relay to open the door; if the communication content does not conform to the Bluetooth access control The setting of the controller does not respond. In this way, it is completely free of operation to open the access control, which is convenient for users to use.

Description

technical field [0001] The invention relates to an automatic access control system based on the bluetooth communication function of a mobile phone and a realization method thereof. Background technique [0002] At present, mainstream access control systems generally use passwords or radio frequency cards, or bluetooth cards as the way for users to open access control. The passwords and radio frequency cards are mainly used for the access control of residential buildings, and the bluetooth cards are mainly used for garage access. These access control systems either require the user to perform complex operations such as entering a password, or need to carry additional equipment such as a Bluetooth card, or if the radio frequency card needs to carry both additional equipment and certain operating actions, that is, to find the card from the pocket, Then place the card in front of the card reader. Among them, the Bluetooth card access control is the easiest to use. It does not r...

Problems solved by technology

However, this design has a major problem, that is, it is very troublesome for the user to operate. The user needs to take out the mobile phone and open the application program before opening the access control. The complexity is far more than the existing common methods, which directly leads to The current mobile phone Bluetooth access control products are difficult to promote. In addition, in the actual use environment, Bluetooth devices can only connect to a small number of devices at the same time, and the speed of establishing connections is relatively slow. If multiple people use it at the same time, it is very likely to be blocked. If one or several users occupy the connection but do not open it, everyone will not be able to enter. The above problems have made this type of Bluetooth access control never popular.

In order to solve this problem and use smart phones to manage access control, an access control management system based on the NFC function of smart phones has recently appeared. It uses the NFC near-field communication function of smart phones to communicate with access control. Its operating principle is the same as that of traditional radio frequency cards. The same, and can be flexibly managed by the application program on the smartphone. At the same time, because the operation of NFC requires close contact, there will be no remote monitoring, simultaneous connection of multiple devices, etc., so its security and stability issues are easy to control and relatively simple to implement , so the system has many practical applications; but on the one hand, the system still requires the user to take out the mobile phone to swipe the mobile phone, which is not too convenient compared with the radio frequency card; on the other hand, only some mobile phones are equipped with the NFC function, so the not widespread
