程序通过采集输入信息，与FPGA的存储值进行比较，如果密码正确，则开锁电路打开；如果密码错误，锁不打开，并且计数器进行+1操作；累计3次输入密码错误，给警报一个高电平，让其报警。(By collecting input information, the program compares with the storage value of FPGA. If the password is correct, the unlocked circuit opens; if the password is wrong, the lock is not open, and the counter performs the +1 operation; the cumulative 3 time input password error gives the alarm a high level and allows the alarm to be sent to the alarm.)
