MEMORIZED TESTING AND MEASUREMENT TECHNOLOGY

介绍一种由传感器、适配放大器、A／D变换器、存储器、控制器、接口电路和电池组成的微型测试仪器。它具有微小的体积，能耐受高的冲击加速度和较高的环境温度，微功耗，不需引线，能放置到被测体内；如工作着的内燃机活塞内，高速旋转的部件上，几千米深的石油井下，飞行的弹丸内，啮合中的齿轮上，发射中的炮膛内，应用到许多不便于引线的场合。在被测对象工作过程中把需要的信号记录下来，待过程结束后取出装置，用计算机读出和处理数据。还介绍了它的组成原理，存储测试理论，精度保证，ASIC和典型应用。

The paper introduces a kind of micro-sized instrumentation made up of a senser,adaptive amplifier,A/D converter,memory,controller,interface circuit and a power source.It is of small size,capable of working under high impact acceleration and high enviromental temperatures.It has very low power consumption,is leadless and can be installed within object being measured,as e.g.within the piston of a running engine,or an element rotating at high speed,located several kilometers deep in an oilwell,in a projectile on flight,agear in mesh,or within the bore of a firing artillery.Suitable for use under situations in which it is difficult to set leads,it records the required information during the working process to be taken out after-wards,so that the data can be read and processed with a computer.The paper reveals the configuration in principle,giving the fundamentals of memorized testing and asument,measures of accuracy guarantee,ASIC and some typical applications.
