Design of Ultrasonic Password Door Model

Abstract:

The system consists of hardware and software, hardware use STC89C54RD+ as the control core, and combining with ultrasonic circuit, stepping motors, monitors, AT24C02, 4 × 4 key circuit and DS1302 circuit. The system first determines whether within the set time range, if yes, start Ultrasonic to measure distance, and determine the opening and closing; otherwise, The system is in the password door state, only the administrator enter the correct password, the door can open. System use stepping motor’s rotation to simulate opening and closing. The system is stable and reliable, Relatively strong practicality, Function relatively complete, The performance price ratio is higher, cost, it has a certain use and reference value.
