Automatic access control system based on mobile phone Bluetooth communication and implementation method thereof

Abstract

The invention discloses an automatic access control system based on mobile phone Bluetooth communication and an implementation method thereof. The automatic access control system comprises an access controller mounted at an entrance, a mobile phone, an access control program, a remote management server and the like, wherein a Bluetooth communication module, a data processing unit and a relay control circuit are arranged in the access controller; after the mobile phone of a user is equipped with the access control program, the user can obtain authorization and key information provided by the management server according to the user identity; when the user is located near the Bluetooth access controller, the mobile phone and the access controller are communicated through a Bluetooth signal; the Bluetooth access controller judges whether the door can be opened according to communication content, if the door can be opened, the access controller controls a relay to open the door automatically, or a door opening switch is activated, and the relay can be controlled to open the door once the user presses the switch; and if the communication content is inconsistent with the setting of the Bluetooth access controller, no reaction is performed. Therefore, the door is opened without operation, and convenience is provided for the user.

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
