These drawbacks of mechanical lock to a new kind of electronic trick lock, the lock provides a great space for development. The design USES the single chip microcomputer as main control chip, combining with the peripheral circuit, electronic password control system by combination lock, a total of six password, each value in the range of 0 ~ 9, the user can set and modify the password, sound and light hint every password button. Users want to play the lock, must first by providing keyboard input the correct password to have a prompt when password input error, in order to improve the security, when the password input error will report to the police for ten minutes, three times during the password you entered is invalid, to prevent the thief tempted password many times. Four password input is correct at the same time, to open the lock. Lock has backup battery, can only be set when the internal power on reset or change the password, so, just outside the door keys cannot be modified or set the password, so that the secrecy of strong, high flexibi
