Abstract: After introducing the characteristic of ARM technique, the paper designed a store-while-recording seismograph for the need of underground coalmine seismic prospecting. In this seismograph we adopt the idea of distributive recording, store-while-recording and collecting data after recording, realized the acquisition, storing and collecting of seismic data. We designed the A/D data acquisition circuit, ARM control system circuit, transplanted imbedded Linux system, and completed the seismic wave acquisition function. Finally the experimental prototype was manufactured, the performance in experiment was showed and the application example was given.
