摘　　要：本文设计了一种医用离心机自动实时转速检测系统,以实现高速离心机转盘转速的精确检测。本系统以STC89C52单片机为中央控制单元,选用霍尔传感器进行转速测量,采用无线发射模块进行数据传输,最后进行数据处理,转速结果实时在显示屏上显示。本系统采用霍尔元器件输出脉冲计数的方法来实现对电机转速的数据化测量,利用单片机的中断系统结合无线发射模块,采用模块化编程的方法进行软件设计,全数字信号输出并显示。与传统检测方法相比,具有输出信号稳定、频率响应高、抗干扰能力强、检测准确度高的优点。In this paper, an automatic real-time rotating speed detection system was designed for the accurate detection of rotation speed of the high-speed centrifuge. This system used STC89C52 microcontroller as the central control unit, Hall sensor for rotating speed measurement, and wireless transmission module for data transmission. After data preprocessing, the speed result was finally displayed on the screen in real time. The system adopted pulse counting method of Hall component to realize the data measurement of the motor speed. It used the interrupt system of microcontroller combined with the wireless transmission module, used modular programming method to design the software, and realized the output and display of whole digital signal. Compared with the traditional detection method, it has the advantages of stable output signal, high frequency response, strong anti-interference ability and high detection accuracy.
