Abstract
The invention provides an electronic password lock system. The electronic password lock system includes a master processing unit, and an infrared receiving device, an electromagnetic lock, a display device, a main keyboard and an alarm device which are connected with the master processing unit; and also includes a slave processing unit, and an infrared emission device and a slave keyboard which are connected with the slave processing unit. The master processing unit compares a password inputted from the master keyboard or the slave keyboard by a user with a preset password, if a comparison result is correct, an instruct is sent out for unlocking the electromagnetic lock, and if a comparison result is wrong, an instruct is sent out for triggering the alarm device. Compared with the prior art, the electronic password lock system provided by the invention uses infrared devices and programmable processing units, the cost is reduced, and the user interaction is increased.
Description
Technical field

As a further improvement on the present invention, described is embedded scm from processor.
As a further improvement on the present invention, described Master Keyboard is 4X4 matrix keyboard.
As a further improvement on the present invention, described is 3X4 matrix keyboard from keyboard.
As a further improvement on the present invention, described electromagnetic lock comprises an electromagnetic relay.
As a further improvement on the present invention, described warning device is that electromagnetism is hummer.
Compared with prior art, electronic password lock provided by the present invention, possesses distant control function, can realize Password Input, password shows, unblanks, reports to the police, complete the machine keyboard unblank and remote control reception after unblank.This circuit is simple, easy to operate, reliability is high, is adapted at using in multiple fields.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing relevant of the present invention in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is electronic coding lock system the first embodiment main frame schematic diagram of the present invention;
Fig. 2 is electronic coding lock system the first embodiment slave schematic diagram of the present invention.
Wherein, Reference numeral is:
Embodiment
Below with reference to each embodiment shown in the drawings, describe the present invention.But these embodiment do not limit the present invention, the conversion in the structure that those of ordinary skill in the art makes according to these embodiment, method or function is all included in protection scope of the present invention.
Shown in ginseng Fig. 1 and Fig. 2, be the first embodiment of Puzzle electronic lock system provided by the present invention, whole system is divided into two parts, i.e. main frame receiving circuit and slave radiating circuit.Main frame receiving circuit be by monolithic processor controlledly having that Password Input, password show, unblank, the electric circuit constitute of warning and infrared reception, mainly complete the machine keyboard unblank and receive after unblank.Slave radiating circuit is the electric circuit constitute that has Password Input, infrared emission by monolithic processor controlled, be mainly by password by infrared transmission, thereby by the infrared reception of host machine part, unblanked.
Main frame receiving circuit is by STC89C51 single-chip microcomputer 14, infrared receiving device 10, Master Keyboard 15, liquid crystal display 11, alarm 17, the compositions such as electromagnetic lock 16 and reset circuit 12.Slave radiating circuit is mainly by clump processor A T89C51 single-chip microcomputer 23, and infrared launcher 20, from keyboard 24 reset circuit 21 compositions such as grade.
STC89C51 is the read-only storage of a kind of band 4K byte flash memory programmable and erasable, and low-voltage, the high-performance CMOS 8-bit microprocessor of device (FPEROM-Flash Programmable and Erasable Read OnlyMemory), be commonly called as single-chip microcomputer.The AT89C51 of ATMEL is a kind of efficient microcontroller, and AT89C5 single-chip microcomputer provides a kind of dirigibility high and inexpensive scheme for a lot of embedded control systems.
Infrared remote control system is generally comprised of infrared launcher 20 and infrared receiving device 10 two large divisions.Conventionally for signal can better be transmitted, transmitting terminal is modulated to burst signal by base band binary signal, by infrared transmitting tube, launches.Infrared launcher 20, conventional transmitter is infraluminescence diode, it removes pulse code telecommand to control controlled device with infrarede emitting diode transmitting infrared ray, in controlled device, all there is corresponding infrared light-electric transition element, by this conversion, corresponding light signal is converted to electric signal.
The receiving circuit that infrared receiving device 10 is comprised of an infrared receiving terminal conventionally.Conventional infrared receiving device has infrared receiving diode, phototriode etc.
In the present embodiment, slave partly adopts 3 * 4 matrix keyboards, and host machine part adopts 4 * 4 matrix keyboards.Matrix keyboard is using a part for I/O line as line, and another part is as alignment, and button is arranged on the point of crossing of line and alignment, and it is to determine concrete key number by detecting the method that keyboard has or not closure and search the key number of closed key.Conventionally because of the elastic reaction due to mechanical contact, contact closed and disconnected moment to electrically contact situation unstable, cause the jitter phenomenon of voltage signal, for fear of closure once, cause many processing of CPU, conventionally take debounce to move measure.
The SCM Based infrared coded lock system of kind provided by the present invention, this system possesses distant control function, can realize Password Input, password shows, unblanks, reports to the police, complete the machine keyboard unblank and remote control reception after unblank.This circuit is simple, easy to operate, reliability is high, is adapted at using in multiple fields.
Be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should make instructions as a whole, technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only for the illustrating of feasibility embodiment of the present invention, and they are not in order to limit the scope of the invention, and does not allly depart from skill spirit of the present invention.Within the equivalent embodiment of doing or change all should be included in protection scope of the present invention.
