一、前言采用集流环技术来测量旋转机械的力学参数存在诸多弊病,例如现场安装要求高、调试十分麻烦,耐线速度低,运转一段时间后会因碳刷磨损导致信噪比下降,易受振动和冲击的影响等等,致使其使用受到一定的限制。特别是许多工业现场因不能安装集流环而使测试工作无法进行,因此,在某些场合下采用无线电遥测技术进行测量更为方便、可靠,并充分显示了其先进性。我们于1983年研制成 ZJ-2型旋转件近程遥测仪,并于同年5月通过鉴定。随后做了大量
I. INTRODUCTION There are many shortcomings in the use of slip ring technology to measure the mechanical parameters of rotating machinery. For example, the requirements of on-site installation are very high, the debugging is very troublesome, the wire speed is low, and the signal-noise ratio decreases due to the carbon brush wear after a period of operation. By the impact of vibration and impact, etc., resulting in its use subject to certain restrictions. In particular, many industrial sites are unable to test their work by failing to install a slip ring. Therefore, using radio telemetry to make measurements is more convenient, reliable and fully demonstrated in some cases. We developed in 1983 ZJ-2 rotating parts near telemetry, and in May the same year by the identification. Then done a lot
