基于51单片机的电子密码锁设计

AbstractWith the rapid development of China's economy and the gradualimprovement of national living standards,people have a higher standard ofpursuit in all aspects of daily life.Take the locks that our family can't livewithout as an example.From ancient Chinese history,there have been recordsand uses of various locks.Today,people are pursuing more than just a tool tolock doors.People's pursuit of locks is embodied in a sense of psychologicalsecurity and advanced technological experience in the use process.The subject is radio electronic code lock.The project chooses STC89C51controller to complete the core work,including main control part,display part,alarm part,electromagnetic lock control,infrared remote control receiving andpower supply.Alarm selection buzzer.LCD1602 is selected to display therelevant information.Users can input password data by keyboard or infraredremote control,the system can judge whether the password data is correct,control the opening and closing of the electromagnetic lock module,and thekeyboard can modify the password.The software is designed by C.It is simpleto develop by C.The special Keil design tool of MCU is used to complete theexecution of program files.After the system software design is completed,thesystem is simulated by Proteus,and the function is verified successfully.Tooptimize the design and complete the system design requirements.Keywords:STC89C51;password lock;infrared remote control;wireless
