신호등으로 부터 송출된 AC를 AC모니터부(11,12)를 통해 순차적으로 인버터(NR3-NR6)와 오아게이트(OR1)로 공급해서 디지탈신호로 변환시키는 아날로그/디지탈변환부(1)와, 이 아날로그/디지탈변환부(1)의 디지탈신호를 받아 원쇼트발생회로(21,22)가 동작되어 카운터(23,24)의 계수동작에 의해 32K비트/초로 세분화되도록 ROM(31.32)의 어드레싱을 제어하는 ROM어드레싱제어부(2), 음성신호가 ROM(31.32)에 저장되어있는 음성ROM(3), 이 음성ROM(3)으로 부터 출력된 디지탈음성신호를 아날로그 신호로 변화시켜주는 디지탈/아날로그변환용 저항어레이(4), OP앰프(OP1,OP2)의 동작에 의해 저항어레이(4)로부터 변환된 음성신호에서 불필요한 신호를 제거해주는 저역통과여파기(5), 톤이네이블부(61)의 제어하에 정확한 음성신호송출후 톤발생회로(61)(63)를 동작시켜 톤을 발생시키는 톤발생부(6), 상기 아날로그/디지탈변환부(1)의 인버터(NR3-NR6)의 출력신호가 원쇼트발생회로(81-84)의 오아케이트(OR2-OR5)에 공급되어 해당 위상(Phase)에만 출력인가시키는 아날로그스위치제어부(8), 아날로그스위치(7′,7″)의 동작에 의해 상기 저역통과여파기(5)의 음성신호와 상기 톤발생부(6)의 톤신호를 선택해서 송출시키는 아날로그스위치(7) 및, 음성증폭기(91,92)로 상기 음성신호 및 톤신호를 증폭시켜주는 음성증폭부(9)로 구성된 것을 특징으로 하는 맹인용음성발생회로.An analog / digital converter 1 for supplying AC transmitted from a traffic light to the inverters NR3-NR6 and OA gate OR1 sequentially through the AC monitor units 11 and 12 and converting them into digital signals; In response to the digital signal from the analog / digital converter 1, the one-shot generating circuits 21 and 22 are operated to control the addressing of the ROM 31.32 to be subdivided into 32 K bits / second by the counter operation of the counters 23 and 24. ROM addressing control section 2, audio ROM (3) in which audio signals are stored in ROM (31.32), and digital / analog conversion for converting digital audio signals output from the audio ROM (3) into analog signals. Under the control of the low pass filter 5 and the tone enable unit 61 which remove unnecessary signals from the voice signal converted from the resistor array 4 by the operation of the resistor array 4 and the OP amplifiers OP1 and OP2. After transmitting the correct voice signal, the tone generating circuits 61 and 63 are operated to generate the tone. The output signal of the tone generating section 6 and the inverters NR3-NR6 of the analog / digital converting section 1 is supplied to the orients OR2-OR5 of the one-shot generating circuits 81-84 and corresponding phase ( The audio signal of the low pass filter 5 and the tone signal of the tone generator 6 are selected by the operation of the analog switch control section 8 and the analog switches 7 ', 7 " And a voice amplifier (9) for amplifying the voice signal and the tone signal with an analog switch (7) for transmitting and a voice amplifier (91,92). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
