Smart access control system

Abstract

The invention discloses an intelligent access control system, which includes: a cloud server, a mobile terminal installed with a system application program, and an access control terminal; the cloud server and the mobile terminal realize data intercommunication in an existing wireless or wired manner; the cloud The server and the access control terminal adopt the NB-IOT communication module to realize data intercommunication; the access control terminal includes: a controller, a safety lock, a battery, an information collection module, a dynamic sensing module, an input module, a voice broadcast module, a lock body detection module and NB‑IOT communication module. Because the cloud server and NB-IOT communication module are used to realize the control and status feedback of the access control terminal, the user can easily realize the remote control of the security lock, so it has the effects of low cost, low power consumption, excellent structure, and real-time updated notifications The information further enhances the humanization function of the system.

Description

technical field [0001] The present invention relates to an intelligent access control system, more specifically, the present invention relates to an intelligent access control system applying NB-IOT communication technology. Background technique [0002] The cellular-based Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network. It is an emerging technology that can be widely used around the world. It has the characteristics of wide coverage, multiple connections, low speed, low cost, low power consumption, and excellent architecture. NB-IOT uses the license frequency band, and can be deployed in three ways: in-band, guard band, or independent carrier, and coexists with the existing network.

Problems solved by technology

[0004] However, in this structure, due to the basic setting of the smart lock using the BLE module, it needs to be paired in advance, the setting process is cumbersome, and limited by the NB-IOT communication cost, the number of connections between the controller and the cloud server has a clear limit. However, in the information transmitted during a single connection, the data used to transmit signals such as dormancy, unlocking, and locking only occupy a small part of the total information capacity, resulting in a waste of information transmission resources

In addition, there will be no reminder message when the door is opened when the verification is passed. The function is single and not humanized enough.
