Design of Vibration Monitoring System of Coal Mine Equipments Based on DSP and ARM

In order to solve problems of high cost, large volume and poor flexibility of collecting card and IPC scheme commonly used in vibration monitoring of coal mine equipments, the paper introduced a design scheme of vibration monitoring system of coal mine equipments which takes dual-CPU of TMS320C6713B DSP and LPC2468 ARM as core and combines with AD converter and dual-port RAM. The system uses DSP to analyze spectrum and Hilbert spectrum of collected vibration signal, and ARM to realize functions of parameter configuration, data storage and data transmission. The experiment result showed that the system's error of vibration test is less than 5% and can meet with real-time requirement of vibration monitoring of coal mine equipments.
