| 摘要：现代工业中，广泛应用旋转物体为电动机或舵机驱动各种生产机械和装备，它们的作用是将电能转换为机械能，衡量机械能的直接物理量就是转速[1]，这对判断旋转物体的性能有至关重要的作用，因此，实时测量并显示转速是很有必要的。旋转物体的转速的测量方法分为模拟式和数字式两种。模拟式采用测速发电机为检测元件。数字式通常采用光电编码器、霍尔元件等为检测元件。本文将以数字式的线性霍尔传感器为基础，运用M/T测速法，以STM32单片机为控制核心，运用线性霍尔传感器为测量元件的非接触式测量传感装置，对旋转物体的转速以及位置进行测量。单片机计算出转速与相应角度并且输送至存储装置以及上位机显示。该方法具有结构简单，有一定精确度并且成本低等优点。21574 关键词：转速测量角度测量STM32线性霍尔元件M/T法 毕业论文设计说明书（论文）外文摘要 Title Research on the system of the objects rotation speed and position which based on Microcontroller STM32 Abstract In modern industry, a variety of production of machinery and equipment are widely driven by electric motor and servo ,the effect of the motor and servo is to convert electrical energy into mechanical energy. Speed is a direct physical to measure the mechanical energy, when analyzing the performance of the motor, it has a crucial role. Thus, real-time measurement and display speed is necessary. Motor speed measurement method is pided into two types of analog and digital. Analog type uses tacho generators as detection devices while digital detection devices commonly used optical encoder, the Hall element, etc. This article will use digital linear Hall sensor as foundation,use STM32 as micro-controller core and use M / T velocimetry while using linear Hall sensor element as non-contact measurement solutions which can measure the rotation speed and the position of the object . Micro-controller calculates out the speed and the corresponding angle and then tranfers the result to the storage device and the PC display. This method has a simple structure which can provided a certain accuracy and low cost.
