Abstract
The utility model discloses an electronic coded lock which comprises a microprocessor, a memorizer, an anti-theft alarm device, a touch screen, a liquid crystal display, a camera, a radio frequency identification device (RFID) card reader, and an electronic control device. The memorizer, the anti-theft alarm device, the touch screen, the liquid crystal display, the camera, the RFID card reader, and the electronic control device are respectively connected with the microprocessor. The microprocessor is an advanced reduced instruction-set computer machine 9 (ARM9) chip AT91RM9200. Due to the facts that two identification methods of identifying card swiping information and entering passwords on a touch screen through the RFID reader are adopted and a double anti-theft device with camera shooting and the anti-theft alarm device alarming is adopted, the electronic coded lock has a strong security and high anti-theft performance, and can be widely used for anti-theft door locks and automobile door locks in places such as banks, families, offices, and hotels.
Description
Technical field
The utility model belongs to technical field of electronic equipment, relates to a kind of electronic password lock.
Background technology
Along with the development of society, people's antitheft consciousness is more and more stronger, and is more and more higher to the security requirement of family, office space, automobile door lock.Mechanical lock structure is simple, and key is joined by imitative easily.Electronic lock is of a great variety, and spread in performance is uneven.Thereby a kind of simple in structure, strong security, electronic password lock that theftproof performance is high are provided is the requirement of society.
The utility model content
Technical problem to be solved in the utility model provides a kind of electronic password lock, adopt by RFID reader identification card using information and two kinds of recognition methods of touch-screen input password, adopt camera shooting and the burglar alarm double anti-theft device of reporting to the police, have extremely strong confidentiality and high theftproof performance.
The technical solution of utility model is as follows:
A kind of electronic password lock comprises microprocessor and is connected memory, alarm against theft, touch-screen, liquid crystal display, camera, RFID card reader and the electric control lock that is connected with microprocessor.
Microprocessor is ARM9 chip AT91RM9200.
AT91RM9200 is that Atmel company is based on 16/32 RISC of high-performance, low-power consumption (Reduced Instruction Set Computer) microprocessor of arm920T nuclear, inner integrated abundant peripheral hardware resource, be applicable to require the aspects such as Industry Control of peripheral hardware aboundresources, low in energy consumption, work strict and steady, such as built-in industrial control, Medical Devices, network service, mobile computing etc.
The high primary frequency of AT91RM9200 microprocessor is 180MHz, and it is two-way, 32 external data bus are supported 8,16,32 bit data width, and 26 bit address buses can be to maximum 64MB space addressing.
The AT91RM9200 Embedded very abundant peripheral functional modules, comprise global function MMU virtual memory management unit, inner 16kBSRAM and 128kB ROM, the EBI interface controller, the clock and the PMC (power source management controller) that strengthen, sheet internal oscillator with 2 PLL (phase-locked bad), 4 programmable external timing signals, comprise Interruption, house dog, the system timer of second counter, the real-time clock that band is reported to the police and interrupted, with 8 grades of priority, AIC (advanced interrupt control unit) that can single shielding interrupt source, 7 exterior interrupt and 1 quick-speed interruption source, 4 32 I0 controller, 20 passage peripheral data controllers (PDC or DMA), 1 10Mbits-1/100Mbits-1 ethernet controller, 1 USB 2.0 host interface, 1 USB 2.0 equipment interface, 2 multimedia card interfaces, 3 SSC (synchronous serial interface controller) (compatible IIS), 4 UASRT (universal synchronous/asynchronous serial port), 1 master/slave SPI (serial device interfaces), 1 two-wire serial interface TWI (holotype), JTAG/ICE interface etc.
Beneficial effect:
The utility model electronic password lock adopts by RFID reader identification card using information and two kinds of recognition methods of touch-screen input password, adopts camera shooting and the burglar alarm double anti-theft device of reporting to the police, and has extremely strong confidentiality and high theftproof performance.
Description of drawings
Fig. 1 is the utility model electronic password lock theory diagram.
The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
As shown in Figure 1, a kind of electronic password lock comprises microprocessor and is connected memory, alarm against theft, touch-screen, liquid crystal display, camera, RFID card reader and the electric control lock that is connected with microprocessor.Microprocessor is ARM9 chip AT91RM9200.
The RFID radio frequency identification is a kind of contactless automatic identification technology, and it is automatically identified destination object and obtain related data by radiofrequency signal, and identification work need not manual intervention, can work in various adverse circumstances.The RFID technology can be identified high-speed moving object and can identify simultaneously a plurality of electronic tags, and is swift and convenient to operate.
The RFID radio frequency identification is a kind of contactless automatic identification technology, and it is automatically identified destination object and obtain related data by radiofrequency signal, and identification work need not manual intervention, can work in various adverse circumstances.The RFID technology can be identified high-speed moving object and can identify simultaneously a plurality of electronic tags, and is swift and convenient to operate.
The user is at first by RFID reader identification card using information, microprocessor is determined to swipe the card errorless, prompting user input password, the user is then by touch-screen input password, microprocessor is with password and pre-stored password comparison in memory, find correctly, then show correctly by liquid crystal display, and then open electric control lock.If the microprocessor judges card using information is incorrect and the password mistake, then send alarm signal, simultaneously camera shooting, perpetuation of testimony.If in card using information and the password the same mistake is arranged, equally correct, then electric control lock is not opened, and warning device is not reported to the police yet, and liquid crystal display shows error message.
The utility model electronic password lock has strong security, advantage that theftproof performance is high, can be widely used in the occasions such as the safe-guard door lock in bank, family, office space, hotel and automobile door lock.
