principle

With 51 series single chip microcomputer (at89051) as the core and corresponding hardware circuit, it completes the functions of password setting, storage, identification and display, driving the electromagnetic actuator and detecting its driving current value, receiving the alarm signal sent by the sensor, sending data, etc. The single chip microcomputer receives the input code and compares it with the password stored in EEPROM. If the password is correct, it drives the electromagnetic actuator to unlock; If the password is incorrect, the operator is allowed to re-enter the password up to three times; If the three times are not correct, the single chip microcomputer will give an alarm to the intelligent monitor through the communication line. The single chip microcomputer sends each unlocking operation and the driving current value of the electromagnetic actuator as the status information to the intelligent monitor, and also sends the alarm information received from the sensor interface to the intelligent monitor as the basis for intelligent analysis
