DEVELOPMENT OF ANTI-THEFT DOOR SYSTEM FOR SECURITY ROOM

The ultimate purpose of developing an electromagnetic door lock is to enforce security features of the entire building structure, equipped with appropriate management control. In this paper I have designed system that allows unlocking a secure door through controlling the "Time Zone". The main aim of this paper is to help users how to improve the door security of sensitive locations, from car parks, shopping centers or corporate head offices to airports, banks or nuclear power plants, while they are not at working places or homes. This paper will focus on programming to lock or unlock the door via PC. Parallel Port programming by Visual Basic 6.0 in depending on "Time Zone" to increase security. Both software and hardware for the system were developed in this paper by using LEDs, electronic circuit, magnetic lock, relays, sensors and some mechanical system to demonstrate the response of the output and input devices. Integration of hardware and software were done to create a simple PC-based control system. A time zone is a user-defined period of time. Time zones can regulate cardholder access, automatically lock/unlock doors, regulate outputs, or arm/disarm auxiliary inputs and supervised inputs.
