Intelligent lock encyclopedia
trait
Convenience: A. Smart locks are different from ordinary mechanical locks, and have an automatic electronic induction lock system. When the door is closed, the system will automatically lock. Smart locks can be unlocked by fingerprints, touch screens and cards. B it is inconvenient for general fingerprint locks to use password/fingerprint registration function, especially for the elderly and children. A single smart lock can open its unique voice prompt function, making the user's operation more convenient.
Security: A. General fingerprint password locks are in danger of password leakage. Recently, the smart lock also has virtual password function technology, that is, any number can be entered as a virtual password before or after the registered password, which effectively prevents the registered password from being leaked and can unlock the lock at the same time. B. In the common residential security environment, the general door lock handle opening method cannot guarantee sufficient security performance, so it is easy to drill a small hole from the outside of the door, and then turn the handle with steel wire to open the door. Many smart locks are guaranteed by patent technology. A safety handle button is added to the indoor handle, and the handle door can be opened only by pressing the safety handle button, which brings a safer use environment. (At the same time, according to the needs of users, you can selectively set this function through simple operations. C. Recently, the touch screen of the smart lock palm will automatically display and automatically lock in 3 minutes. Whether the password is set, whether the door lock is opened or closed, the number of registered passwords or door cards, as well as battery replacement tips, warning that the lock tongue is blocked, encountering low voltage, etc. , all displayed on the screen, intelligent and intelligent control.
Security: The latest smart lock is different from the previous "open before scanning" mode. The scanning method is simple. Just put your finger where you are scanning and scan it from top to bottom. There is no need to put your finger on the scanned place. The scanning method reduces the fingerprint residue, greatly reduces the possibility of fingerprints being copied, and is safe and exclusive.
Creativity: People pay little attention to the appearance of traditional mechanical locks. Smart locks not only meet people's tastes in terms of design, but also create smart locks with the same sense of intelligence as Apple. Smart locks have been quietly listed.
Interaction: Intelligent door lock has built-in embedded processor and intelligent monitoring. If it is taken in, it has the ability to interact with tenants at any time and can take the initiative to report the TV visitors of the day. On the other hand, tourists can even remotely control the smart door lock to open the door for visiting guests.
special technology
In the field of security technology, the electronic password lock with anti-theft alarm function replaces the traditional mechanical password lock, which overcomes the shortcomings of mechanical password lock, such as less passwords and poor security performance, and greatly improves the technology and performance of password lock. With the development of large-scale integrated circuit technology, especially the appearance of single chip microcomputer, intelligent password lock with microprocessor has appeared, which not only has the function of electronic password lock, but also has the function of intelligent management and expert analysis system, making password lock highly safe and reliable and has been widely used. This paper introduces an intelligent combination lock with 5 1 series single chip microcomputer as the core, and expounds its working principle, basic function block diagram, key design technology and software workflow in detail.
fundamental principle
Intelligent password lock system consists of intelligent monitor and electronic lock. The two are placed in different places, and the intelligent monitor provides the power needed by the electronic lock and receives the alarm information and status information sent by it. In this paper, line multiplexing technology is used to make a two-core cable used for power supply and information transmission, which improves the reliability and security of the system.
1. 1 Basic principle of intelligent monitor
The intelligent monitor consists of single chip microcomputer, clock, keyboard, liquid crystal display, memory, demodulator, line multiplexing and monitoring, A/D conversion, buzzer and other units. It mainly completes the functions of communication with electronic lock, intelligent analysis, communication line safety monitoring and so on.
The intelligent monitor is always in the receiving state, receiving the alarm information and status information in fixed format sent by the electronic lock. For the alarm information, an audible and visual alarm will be given immediately through the LCD and buzzer; The state information is stored in the memory, compared with the historical state of the electronic lock before this moment, the change trend is obtained, the future state change is predicted, and the corresponding information is provided to the personnel on duty for decision-making through the LCD. When the intelligent monitor establishes communication with the electronic lock, it monitors the change of power supply current flowing through the communication line in real time through the A/D converter, which effectively prevents the damage caused by human factors and ensures the smooth communication line.
1.2 basic principle of electronic lock
The electronic lock is also based on 5 1 series single chip microcomputer, and cooperates with the corresponding hardware circuit to complete the functions of password setting, storage, identification and display, driving electromagnetic actuator and detecting its driving current value, receiving sensor alarm signal, sending data and so on.
The MCU receives the typed code and compares it with the password stored in EEPROM. If the password is correct, it will drive the electromagnetic actuator to unlock. If the password is incorrect, the operator is allowed to re-enter the password for up to three times; If it is incorrect for three consecutive times, the single chip microcomputer will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends the driving current value of the electromagnetic actuator and each unlocking operation as state 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.
key technology
In order to improve the security and reliability of intelligent password lock, this paper not only takes measures in device selection (such as using devices with low power consumption and wide temperature range), but also adopts some key technologies in design.
2. 1 line multiplexing technology
Intelligent monitor and electronic lock are placed in different places. If the communication line and the power supply line are separated, it is bound to increase the number of cable cores and increase security risks. In this paper, line multiplexing technology is adopted, and only one two-core cable is used to realize power supply and information transmission. The schematic diagram is shown in Figure 3.
At the sending end, the electronic lock boosts the modulated data signal through the pulse transformer T and sends it out; At the receiving end, the pulse transformer T reduces the voltage of the received data signal and sends it to the demodulator to reduce the loss of the carrier signal in the transmission process. In order to reduce the interference between communication and power supply, the choice of choke L and coupling capacitor C should be considered comprehensively.
Let the carrier frequency fo=400kHz and L=33.7μH to ensure that most of the signal energy is transmitted to the receiving end. C 1=0.047 microfarad.
2.2 Current monitoring technology
In order to prevent the communication line from being destroyed and the electromagnetic actuator from burning the coil due to excessive current flowing in the electromagnetic coil for some reason, the current monitoring technology is adopted in the design of the intelligent password lock.
2.3 Data communication and preprocessing technology
The intelligent monitor receives the status information sent by the lock (including lock opening and closing, first password error, second password error, third password error, etc.). ) and the current value flowing through the electromagnetic actuator coil, and read the power supply current value of the communication line at this time, which are combined to form a data block, in which the running state accounts for 1 byte, the power supply current accounts for 2 bytes, and the coil current accounts for 2 bytes. The intelligent monitor is always in the receiving state during the communication with the electronic lock. In order to improve the reliability of communication, this paper adopts the method of repeated transmission in the communication protocol. The electronic lock repeatedly sends each set of data five times. After receiving this set of data, the intelligent monitor adopts large number decoding method to correct errors, which ensures the accuracy of data reception. In addition, in order to save memory, the received data should be preprocessed, that is, after each data is received, it should be compared with the set threshold, and if it is greater than the threshold, it will send out an overrun alarm; If it is less than the threshold, compare the data with similar data received on the same day and keep the larger one. In this way, the data stored every day is the largest of its kind.
2.4 Intelligent analysis
Intelligent analysis and prediction technology is based on each received data block, comparing with the previously recorded similar data values, analyzing the current changes and trends caused by this operation, finding existing problems in time, and reporting them to managers, thus improving the reliability of the whole system.
system software
The intelligent password lock software uses 5 1 series single chip microcomputer assembly language to program the intelligent monitor and the electronic lock respectively. Intelligent monitoring software includes keyboard scanning and LCD display program, buzzer driver program, clock modification and reading program, data communication and preprocessing program, intelligent analysis program and line monitoring program. The electronic lock software includes keyboard scanning and decoding program, liquid crystal display program, communication program, electromagnetic actuator driving and detection program, sensor interface program and other modules. Modular design method is adopted in the process of software design, which is convenient for reading, debugging and perfecting the program.
Intelligent password lock makes full use of the software and hardware resources of 5 1 system single chip microcomputer and introduces intelligent analysis function, which improves the reliability and security of the system. The system has been installed and used in a certain type of safe and is welcomed by users. In addition, the intelligent password lock can form an intelligent distributed monitoring network by slightly changing the software and hardware, which can realize centralized monitoring and management in a certain range, and has a wide application prospect in the fields of finance, insurance, military and other security precautions.
