【摘要】 设计了一个低成本的GPWS汉语语音模拟装置,使之按照同样的规律,输出汉语语音信息。模拟装置逻辑处理单元选用了国产BASIC语言单片机PS1008;语音部分采用新型语音芯片ISD1420。经过与某型飞机的机载GPWS系统对比发现,模拟装置的语音更清晰易辩,静噪更小。此模拟装置可以根据需要,录制与输出其他语种的语言。更多还原

【Abstract】 The paper is an attempt to design a lower-price simulator to the GPWS that may output Chinese voice.A single chip of PS1008is adopted in the device,serving as a CPU and managing the voice output logic.A voice integrated circuit ISD1420is adopted for the voice input and output process,and its inside I /O process is automatic.The simulator is in-stalled independently.The simulator output of the warning voice in Chinese is desirably clear-er than that of onboard one.This device may also be used to input or output other languages.更多还原
