Abstract: Reliability and stability of portable detectors for safety bring about direct effects to safe coalmining. Therefore, a portable multi2pa2
rameter detector based on SPCE06A 162bit sound controller is designed. Firstly, a system design p lan for the device is given. Then, SACM
2000, an audio comp ression algorithm for SPCE06A is p resented. Finally, imp lementation of sound p rocess and voice recognition in this detec2
tor is described detailedly. This design is capable of imp roving stability, reliability and anti2interference of the detector significantly, thus p rovi2
ding an effective detecting measure for safe coal mining.
