The system consists of 80C196KB/KC single chip microcomputer, 27C64 memory, optical coder and its external decode circuit, motor drive circuit, current - limiting circuit, DC servo motor etc.
Design closed-loop command system which control by single chip and optical coder, realize automation of the whole change-target system, monitor and control the whole system real time.
Introduced in this paper is the float water-level measuring instrument in which a new optical coder is used as the acquisition device of the water-level signal.
Using an optical encoder, digital recorder and a data-logging computer on an arm weightlifting machine, F=m and F=ma were significantly different between 25% and 94%, contrary to published reports, but not at 100% of strength.
Tests were performed on a modified Monark cycle ergometer (Varberg, Sweden) equipped with force transducers on the friction belt and an optical encoder for velocity measurement.
The displacement was calculated by the acceleration data being integrated twice and was compared with the results obtained simultaneously by an accurate mechanical displacement sensor based on an optical encoder.
A Synchro/Resolver to digital converter is proposed in this paper.Inorder to meet the needs of high speed servo system for angular position ??measurement,a tracking type Synchro/Resolver to digital converter shouldbe adopted.The design procedure and experiment results of this converter aregive in the paper.The converter not only realizes the angular positionmeasurement in real time,it can also provide the angular speed in analogousand digital forms at the same time.The position output can be both in thepara...
本文首先提出了轴角数字转换器(Synchro/Resolver to Digital Con-Verter)的结构。为满足高速随动系统轴角位置检测的需要,必须采取跟踪型轴角数字转换器。文中给出了此种轴角数字转换器的设计思想和实验结果。它不但可以实现轴角位置的高精度实时检测,同时还能以模拟和数字两种方式给出旋转速度。位置信息可以并行输出,适于与计算机联接,也可以输出正交脉冲,其方式与光学编码器完全一致。
Compared with the optical code device, the angle transducer introduced in this paper is characterized by its easy manufacturing, high reliability and high cost-performance ratio, and can resolve the problems that are hard to deal with by means of common method.
This paper recommended nearest developmental tendency of tactile sensors, proximity sensors, range sensors, optical encoders etc. in the field of robot sensors, and indicated the direction of robot sensors in the further research.
