Electronic lock, it is also based on 51 series single-chip microcomputer (AT89051), with corresponding hardware circuit, complete password setting, storage, identification and display, drive electromagnetic actuator and detect its drive current value, receive sensor sent alarm Signal, send data and other functions.
The MCU receives the entered code and compares it with the password stored in the EEPROM. If the password is correct, the electromagnetic actuator is unlocked; if the password is incorrect, the operator is allowed to re-enter the password, up to three times; if three times If it is not correct, the MCU will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends the unlocking operation and the driving current value of the electromagnetic actuator as the status information to the intelligent monitor at this time, and also sends the alarm information received from the sensor interface to the intelligent monitor as the basis of the intelligent analysis.
