摘要
在设计应用于高温、高压、高冲击等环境下的存储测试系统时,必须同时兼顾信号精度、完整性与系统有限的存储资源。针对这种测试特点,总结归纳了存储测试中几种典型测试系统的采样策略设计方法。分别从采样频率和系统增益两个角度深入探讨,提出了自适应性采样策略的实现手段。实测结果表明,该研究对于确保存储测试技术中数据采集的合理性以及完整性具有十分重要的意义。
For designing storage test system that is applied under environment of high temperature, high pressure and high impact, the accuracy, integrity of signals and limited storage resources of the system have to be taken into account at the same time. In accordance with the features of such test specification, the design methods of sampling strategies of several typical test systems in storage test are summarized. In addition, the topic is investigated thoroughly from two aspects, i. e. , the sampling frequency and system gain, and the implementing measure of adaptive sampling strategy is proposed. Practical test indicates that the research possesses great significance to ensure the reasonability and integrity of data acquisition in storage testing technology.
