語音功能在多參數(shù)檢測儀上的實現(xiàn)

便攜式安全檢測儀的可靠性和穩(wěn)定性直接影響著煤礦生產(chǎn)的安全。設計了一種以SPCE061A 單片機為核心的多參數(shù)便攜式語音檢測儀。首先給出了該系統(tǒng)的總體設計方案，然后介紹了SPCE061A 的音頻壓縮算法SACM 2000，最后詳細論述了語音在儀器上的實現(xiàn)方法。該設計大大提高了檢測儀的穩(wěn)定性、可靠性以及抗干擾性，為煤礦安全生產(chǎn)提供了有效的測量手段。

Abstract：Reliability and stability of portable detectors for safety bring about direct effects to safe coal mining. Therefore，a portable multi-parameter detector based on SPCE06A 16-bit sound controller is designed. Firstly，a system design plan for the device is given. Then，SACM 2000，an audio compression algorithm for SPCE06A is presented. Finally，implementation of sound process and voice recognition in this detector is described detailedly. This design is capable of improving stability，reliability and anti-interference of the detector significantly，thus providing an effective detecting measure for safe coal mining.
