The main components of the intelligent electronic door lock are composed of two parts, the intelligent motor monitor and the electronic lock. The interaction between the two enhances the performance of the intelligent electronic lock. Today, Xiaobian detailed the intelligent electronic door lock hardware components for everyone, I hope that you can use these materials to help you better use smart electronic door locks.
Intelligent electronic door lock hardware component - intelligent monitor
The block diagram of the intelligent monitor is composed of a single chip, a clock, a keyboard, an LCD display, a memory, a demodulator, a line multiplexing and monitoring, an A/D conversion, a buzzer and the like. Mainly complete the communication with the electronic lock, intelligent analysis and security monitoring of communication lines.
The intelligent monitor is always in the receiving state and receives the alarm information and status information from the electronic lock in a fixed format. For the alarm information, the sound and light alarms are immediately sent through the LCD display and the buzzer; for the status information, it is stored in the memory and compared with the historical state of the electronic lock before this time, and the trend is changed to predict the future. The status changes, and the corresponding information is provided to the duty officer through the LCD display for decision making. While the intelligent monitor establishes communication with the electronic lock, the A/D converter monitors the change of the supply current flowing through the communication line in real time, effectively preventing the damage caused by human factors and ensuring the smooth communication line.
Intelligent electronic door lock hardware composition - electronic locks
The block diagram of the electronic lock, which is also based on the 51 series single chip microcomputer (AT89051), with the corresponding hardware circuit, completes the setting, storage, identification and display of the password, drives the electromagnetic actuator and detects the driving current value, and receives the sensor. The function of alarm signal and data transmission.
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.
The above is about the intelligent electronic door lock hardware composition principle and composition of the block diagram introduction, I hope that through these introductions you can understand what is the smart door lock hardware components, know that the intelligent monitor and electronic locks interact to improve the security of the smart door lock system And reliability.
