Abstract

The problems associated with production of electronic devices without corresponding locking system has been a serious concern in the security system. This paper looked into the development of electronic time lock control system in security system. Due to the fact that lives and property may be at stake, it is important to always have a reliable lock system, putting into consideration the high rate of crime and insecurity. The design is made of a keypad unit for entering the access time, a LCD that displays different messages at specific time, a door controller section made up of an H-bridge driver IC that controls the movement of the motor attached to the door and an alarm system that triggers when the conditions are bridged. The whole system is controlled by an AT89S52 microcontroller programmable IC. The setup allows the user to operate in real-time and also preserving the time data if the main power supply fails. The design is meant to prevent unauthorized person from having access to ones properties through the use of times and it‟s focused on security system for buildings, cars, safes, doors and gates.
