摘要

爆炸场压力信号测试过程中,现场干扰容易引起错误的系统触发导致测试失败。针对分布式存储测试系统,提出一种多存少取的测试技术。大容量的测试数据存储实现长时间的信号记录,可避免误触发引起的失效;标记并提取小容量的有效数据段,可改善数据传输和数据处理效率。设计并研制了一种基于多存少取技术的爆炸场地面压力测试系统,测试节点采样速率1Msps、128Gb数据存储、512kW有效数据段提取,并具有Wi-Fi无线网络覆盖。

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.
