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.
