Abstract

During the pressure signal measurement of explosion field, the interference signal of experiment field causes easily the false triggering resulting in the failed measurement. A measurement technology based on mass storage and less read is proposed for the distributed storage measurement system. Long signal acquisition is achieved by mass storage of measurement data, to avoid the failure due to false triggering. On the other hand, small valid data segment is extracted by signal identification, which improves the efficiency of data transmission and data processing. A measurement system based on mass storage and less read technology is designed and implemented for ground pressure of explosion field, and the measurement node is characterized by sampling rate of 1Msps, data storage of 128Gb, valid data segment of 512kW, and Wi-Fi wireless network coverage.

Key words
