语音功能在多参数检测仪上的实现:便携式安全检测仪的可靠性和稳定性直接影响着煤矿生产的安全。设计了一种以SPCE061A单片机为核心的多参数便携式语音检测仪。首先给出了该系统的总体设计方案,然后介绍了SPCE061A的音频压缩算法SACM 2000,最后详细论述了语音在仪器上的实现方法。该设计大大提高了检测仪的稳定性、可靠性以及抗干扰性,为煤矿安全生产提供了有效的测量手段。关键词: 传感器 音频 API函数
Abstract: Reliability and stability of portable detectors for safety bring about direct effects to safe coalmining. Therefore, a portable mulTI2pa2rameter detector based on SPCE06A 162bit sound controller is designed. Firstly, a system design p lan for the device is given. Then, SACM2000, an audio comp ression algorithm for SPCE06A is p resented. Finally, imp lementaTIon of sound p rocess and voice recogniTIon in this detec2tor is described detailedly. This design is capable of imp roving stability, reliability and anTI2interference of the detector significantly, thus p rovi2ding an effective detecting measure for safe coal mining.Keywords: Transducer Audio API function
