一、前言工程遥测技术为旋转机械和行驶机械动态参数测试提供了一个既方便而又精确的测试手段。在某些特殊的情况下,除了用遥测技术外就没有其它的成功方法可用来测量(例如往复式发动机的活塞)。其它一些情况下,不同的测量方法均可采用,但无线电遥测技术仍有使用方便、数据精确可靠的优点。在没有开展无线电遥测之前,要分析旋转轴上的应力、扭矩……等物理量,多半是利用集流环的方法将信号引入到记录仪器上。而分析行驶机械的动态参数则采用有线跟踪法,测量很不方便,尤其在高速行驶条件下甚至得不到测量数据。我国从60年代初期开展工程遥测技术的研究工作,但由于电子元件笨重,未能达到广
I. Introduction Engineering telemetering technology provides a convenient and accurate test method for dynamic parameter testing of rotating machinery and traveling machinery. In some special cases, there are no other successful methods besides telemetry for measuring (for example, reciprocating engine pistons). In other cases, different measurement methods are available, but radio telemetry still has the advantages of ease of use and accurate data. Before radio telemetry was carried out, it was necessary to analyze the physical quantities such as stress and torque on the rotating shaft. Mostly, the signal was introduced into the recording apparatus by using a slip ring. The analysis of the dynamic parameters of the traveling machinery uses the cable tracking method, which is very inconvenient to measure, especially under high-speed driving conditions, even without measurement data. Our country from the early 60s to carry out engineering telemetry research work, but due to bulky electronic components, failed to achieve wide
