【正文】 removal of keys and passwords, and other key 16 keys, enter your password and for the realization of function keys. This design uses a wakeup function keys of the IO low eight IOA0 ~ IOA7 to 4 4 as the control input of the keyboard, which can be rational use of hardware resources and programming flexibility. Recognition keyboard keys are pressed whether the method is: Let all out lines are low, check the traffic on whether there is a highlevel, if there is a statement that a key is pressed, if not, then no keys are pressed (Actual programming keys should be taken into account the impact of jitter, usually always use the software delay processing methods Consumers buffeting). Identify specific keys used scanning method: homebyzero level out and check the level of the carriageway of the changes, if a line from the low level into a high, this trip can be sure this column crosspoint Button is pressed.178。s personality parameters reference template.178。s current / voltage converter chip MAX471. The chip can be measured current I into pairs to the output voltage U, and is measured Wai, high precision, and U output voltage proportional to the measured current I characteristics. Current monitor output voltage service A / D converter, read through the single A / D converter results in the current line was informed of the situation, through the timely detection of abnormal, issued its report.4 system software designSPCE061A the development of online debugger PROBE To achieve. It uses a builtin online SPCE061 Circuit Simulation ICE (InCircuit Emulator) and Sunplus39。s programming and missioning work more convenient and efficient. In addition, IDE software simulation can not connect the simulation board under the simulated conditions of the various functions to the hardware debugger. When the system work, the main function of the call to plete a specific function of the human voice training, training for the future success of voice recognition, according to the order to identify the implementation of the keyboard control operation, according to the different function keys, the implementation of the corresponding procedures, to plete Password changes settings, contrast, shows, and other functions.5 ConclusionThe system uses a SPCE061A 16bit microcontrollers embedded voice processing and control system, easy to use, easy to use, but the speech recognition capabilities have yet to be improved. Electronic password lock technology development so far, has been widely used in higher property security areas as information technology and puter technology and the constant development, voice, electronic password lock technology will have greater development and, ultimately, achieving efficiency, safety And reliable Voiceprint control of the voice of electronic locks.附件：資料2翻譯譯文 譯文標題（3號黑體，居中）（小4號宋體，）………
