Abstract
A single-chip microcomputer infrared remote-control code lock comprises an electromagnetic lock, a code storage chip connected with a single-chip microcomputer, a power supply management chip, an infrared receiving terminal, a display module and an alarm module; and the electromagnetic lock is connected with the single-chip microcomputer. Besides functions of a conventional fixed-keyboard type electronic code lock system, in other words, an operation disc is fixedly disposed on a panel of a lockset, the single-chip microcomputer infrared remote-control code lock additionally possesses the function of using a remote controller for remote control. The disclosed code lock is convenient to use, stable in performances and accurate and efficient in decoding, and helps to improve the reliability and safety of an access control system.
Description
Technical field
The invention belongs to electronic security field, relate to a kind of single-chip microcomputer infrared remote controlled code lock.
Background technology
Coded lock is the one of lock, and during unlatching is a series of numeral or symbol.The password of coded lock is all arrange and the combination of really usually.Partial password lock only uses a rotating disk, and the several video disc in lock or cam are rotated; Also some coded lock is the several thumb wheel circle being carved with numeral of rotation one group, directly drives the machinery that lock is inner.
The system of intelligent cipher lock is made up of intelligent monitor and electric lockset.The two strange land is placed, and intelligent monitor supplies the power supply needed for electric lockset and receives its warning message sent and status information.Be employed herein line sharing technology, electric energy supplied and the shared twin core cable of information transmission, improve the reliability of system, security.
In prior art, coded lock is all provided with cipher input, and such as roller obtains keyboard, by user close in person operating, must cannot realize Remote input password and realizing switch lock.
Summary of the invention
For solving prior art to the technological deficiency that cannot realize switch lock to coded lock Remote input password, the invention provides a kind of single-chip microcomputer infrared remote controlled code lock.
Single-chip microcomputer infrared remote controlled code lock, comprises electromagnetic lock, also comprises single-chip microcomputer, and the code storage chip, power management chip, infrared receiving terminal, display module and the alarm module that are connected with single-chip microcomputer, and described electromagnetic lock is connected with single-chip microcomputer.
Preferably, the keyboard be connected with single-chip microcomputer is also comprised.
Concrete, described single-chip microcomputer is AT89C51RC.
Concrete, described code storage chip is AT24C04.
Concrete, described power management chip is LM7805.
Concrete, described infrared receiving terminal is KS38BL infrared receiving terminal.
Single-chip microcomputer infrared remote controlled code lock of the present invention, except there is the function of traditional retainingf key disc type electronic coding lock system, namely operation keyboard is fixed on the panel of lockset, also add the function by far-end control, easy to use, stable performance, decoding precise and high efficiency, improves reliability and the security of gate control system.
Accompanying drawing explanation
Fig. 1 illustrates the present invention's embodiment schematic diagram.
Embodiment
Below provide the present invention's embodiment.
Single-chip microcomputer infrared remote controlled code lock, comprises electromagnetic lock, also comprises single-chip microcomputer, and the code storage chip, power management chip, infrared receiving terminal, display module and the alarm module that are connected with single-chip microcomputer, and described electromagnetic lock is connected with single-chip microcomputer.
As Fig. 1 provides the present invention's embodiment, with AT89C51 system RC for core.System architecture diagram as shown in Figure 1.Comprise infrared receiving terminal, single-chip microcomputer, buzzer warning functional module, display module, keyboard, electromagnetic lock, power management chip etc.Introduce the hardware circuit of each unit and the function of realization below in detail.
The power management chip of native system provides the voltage of single-chip microcomputer 5V after using LM7805 chip to carry out voltage stabilizing.IR signal reception part uses KS38BL infrared receiving terminal to realize.Launch infrared digital signals if having, take out digital signal data through infrared receiver module, logic pen pulse LED just can flash.Can detect so current whether have infrared signal launch the simplest method.
The display module of system is 8 the stable static state display using MAX7219 to realize, MAX7219 is serial common cathode charactron dynamic scanning displaying driving chip, 3 line serial line interfaces are only used to transmit data, can directly and interface microcontroller, user can also revise its inner parameter easily to realize Multi-bit LED display, therefore the serial ports of single-chip microcomputer can be used easily to send display data, and its time taken is few, convenient programming and the detection to signal
In order to preserve the password that user is arranged, this system uses AT24C04 to preserve as password the password that chip is used for preserving user's setting, the P3.6 of AT89C51 system RC connects the serial-shift clock of SCLK mouth as it of AT24C04, and the SDA mouth that the P3.7 of AT89C51RC meets AT24C04 is as its serial data or address input and output.The password that user is arranged leaves in AT24C04, when needs change or when reading user cipher, and only need to the data change in AT24C04 or reading.
Alarm module described in the present embodiment is reported to the police by hummer sounding, and hummer is connected on the pin P0.4 of AT89C51 system RC, does Current amplifier by PNP type triode, therefore can by the frequency of Single-chip Controlling hummer and buzzing time.When the password of input error is unblanked, system can be reported to the police, PNP type triode conducting is made by P0.4 mouth output low level, hummer two ends power up, the chimes of doom of 1 second is sent by hummer, when there is code error continuous three times, then system can be reported to the police for a long time, and this measure is unblanked to prevent others from illegally souning out.
Above-describedly be only the preferred embodiments of the present invention; described embodiment is also not used to limit scope of patent protection of the present invention; therefore the equivalent structure that every utilization instructions of the present invention and accompanying drawing content are done changes, and in like manner all should be included in protection scope of the present invention.
