Cloud-based smart lock classroom access centralized control system

Abstract: The number of multi-room school classrooms, management behind, sent a cloud of Liu smart door lock and switch financing for coordinated control system, administrators real-time, remote control door lock status by e / s mode of the software system and gain centralized control for . The system is reliable, has greatly improved the efficiency of management and control of the accuracy of the classroom door locks

Keywords: access control; cloud intelligent lock; classroom

1 Introduction

     Access control system is mainly used in staff turnover in public places, to ensure that legitimate

The identity of the people in and out in order to achieve security management. Traditional access control uses have

Unattended way to achieve bound waste of human and financial resources. With automatic identification technology

Development, and gradually the radio frequency identification IC card application to the hotel, residential and parking gates

Ban system [R-27, although the identification of various class access control system IC card RF distance is limited, but

IC card can not easily be copied, greatly improving security and flexibility. School teaching building

The number of multi-room, the property management sector is currently still using the key and lock the door opening, key

Spoon and more difficult to find and can not grasp the classroom open cold-volt state, apparently the current

Managed to not meet the needs of school management. As wireless cloud intelligent lock '3'] of

The advent of the end of the brew behind change management.

Overall two sets of wireless access control system design

     Large number of classrooms, and the current management model behind, administrators can not

Remote real-time control of the classroom door open and closed states, the need to live each nuclear

Real; in addition, because of theft classroom door was forced open and can not be happening

Quickly grasp. Aiming at the existence of time-consuming classroom management deficiencies, proposed a

Kinds of cloud-based smart lock switch can remotely lock and door switch centralized control system, the Department of

Communications. Wireless cloud intelligent lock adopt international standards structures reinforced five bolt lock,

High performance motor drive, with tamper insurance tongue and indoor locked function, switch door into

Line switch door action by adjusting the motor reversing relay, stop action. Electronic lock with

Wireless cloud intelligent lock the current status information can be fed back to the wireless transceiver node, and then on

Transmitted to the system control server.

4 Access centralized control system software design

     Access centralized control system, including Windows-based customer service side of the computer off

End service based on smart mobile terminals Andriod platform. Access centralized control system software

Using C / S structure, based on the customer service side of the computer in Microsoft Microsoft

Visual Studio using C # language development environment under the 2010 smart move on

Customer mobile terminal end and back-end servers are using the Java programming language, server configuration

A dedicated database. Set access control system software architecture shown in Figure 2.
