Method for realizing access control, terminal, access control device and access control system

Abstract

The embodiment of the invention discloses a method for realizing access control, which comprises: establishing PTT connected with a terminal, receiving data packet carrying access control removal request and current geological position information of the terminal from the terminal, acquiring user identification number of the terminal, performing verification according to the user identification number to determine if the terminal is a registered terminal, resolving the data packet carrying the current geological position information of the terminal to obtain the current geological position information of the terminal, judging if the current geological position of the terminal has the right to remove the access control, and removing the access control corresponding to the current geological position for the terminal. The invention also discloses an access control device, the terminal, an assess control system. The invention has the advantages that: an assess control removal request is sent in a PTT mode; the removal of the access control is controlled according to the access control right of the terminal; users do not need to carrier extra cards; and the use by the users is convenient.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing access control, an access control device, a terminal and an access control system. Background technique [0002] At present, for companies, residential quarters, factories and other places, the security of access control is becoming more and more important. In the existing access control system, the traditional way is to open the access control with a key, and the user opens the access control by holding the key; another advanced The method is the induction method. The user scans the sensor through the access control system to open the access control through the sensor held by the user, such as a proximity card. [0003] In the prior art, although the traditional key-opened access control system is cheap in cost, it has an effective lifespan and is easily damaged. After a certain period of time, when the access control system fails or is damaged, the lock cylinder...

Problems solved by technology

[0003] In the prior art, although the traditional key-opened access control system is cheap in cost, it has an effective lifespan and is easily damaged. After a certain period of time, when the access control system fails or is damaged, the lock cylinder and all user keys need to be replaced, and The key to open the access control system is not easy to control the keys. After the user has one key, it is easy to equip multiple keys. In the end, the access control system becomes uncontrollable and the access control system is useless.

Although the induction access control system can solve the key problem very well, the induction increases the cost of the operation of the access control system. Secondly, the additional induction has the disadvantages of being easy to lose, forget, damage and inconvenient to carry.
