Fig. 3 is Intelligent electronic coded lock warning circuit figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing Intelligent electronic coded lock of the present invention is described in further detail.
As shown in Figure 1, Intelligent electronic coded lock of the present invention comprises: central control unit and the input keyboard and the display module that are of coupled connections with central control unit respectively; Wherein central control unit comprises keystroke handling module, decoding module and the main control module that intercouples and connect; Main control module also further comprises: lock/unlock circuit and warning circuit.Main control module adopts ACEX20K family chip EP20K400BC652-2.
As shown in Figure 2, input keyboard is 4 * 4 keyboards.Be provided with input circuit in 4 * 4 keyboards, input circuit comprises six key circuits parallel with one another, and key circuit is comprised of resistance and button.4 * 4 keyboards are only used 11 buttons wherein.The determinant button refers to directly with the key circuit of I/O mouth line by the dynamic scan formation.Each button needs eight I/O mouth lines by dynamic scan, and the button duty on every I/O mouth line can not affect the duty of other I/O mouth lines.Its Circnit Layout is flexible, and software configuration is simple, and the I/O resource that takies is few.At first fixing output 4 behavior high level (receiving power supply), then export 4 and classify low level as, value at 4 row that read in output, usually high level can be dragged down by low level, if 4 row that read in are high level, does not so certainly have button to press, otherwise, if 4 row that read in have one to be low level, so this corresponding row has a button to press certainly, just can get access to like this row value of button.In like manner, obtaining train value also is so, exports first 4 and classifies high level as, then in output 4 behavior low levels, reads in train value again, is low level if who is wherein arranged, and that of so sure correspondence shown button and pressed.Get access to after row value and the train value, be combined into one 8 data, according to different being coded in of realization each button is mated, show at 7 segment encode pipes after finding key assignments.
Display module adopts the light emitting diode field display of common cathode, and it has 8 light emitting diodes, and wherein 7 light emitting diodes consist of seven fonts, and 1 light emitting diode consists of radix point.7 sections displaying blocks are connected with the FPGA interface and are simple, as long as 8 a bit parallels output is linked to each other with the light-emitting diodes tube anode pin of displaying block.The different byte data of 8 bit parallel delivery outlets output can obtain different numerals or character.
As shown in Figure 3, warning circuit comprises: triode Q1, and the ground level of triode Q1 is connected with signal input part, and the current collection level of triode Q1 is connected with power supply, and the emitting stage of triode Q1 is connected with loudspeaker.
Intelligent electronic coded lock of the present invention has 13 buttons: comprise 0～9 totally 10 numerical keys and 1 acknowledgement key, 1 alarm reset key, 1 clear 0 key.Behind the input proper password, can open the door by acknowledgement key, under the state that door is opened, confirm that again password can arrange password after for the first time inputting new password, the password of input shows at eight digit number code pipe, the numeral of input is presented at rightmost at last, every input one-bit digital, and the demonstration of password on charactron moves to left one.High-order zero need not the input, so password can be 1～8.Initial password is 0, after namely powering on, can open the door by acknowledgement key.Men Kaihou can close the door by the button of locking a door, and will again input password after door is shut and just can open the door.In the process of input password, when user's key error password, system will report to the police, and sends chimes of doom by loudspeaker, and when the password mistake occurring continuous three times, then system can report to the police incessantly for a long time, at this moment must can stop by the alarm reset key.
Intelligent electronic coded lock of the present invention has good confidentiality, and anti-theft is strong, can be without key, remember the password advantage such as can unblank, but and Set arbitrarily password figure.Simultaneously, when the input the password mistake time can also start warning device, improved security performance.
Below the preferred embodiment of the invention is specified, but the present invention is not limited to embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, the modification that these are equal to or replacement all are included in the application's the scope.
