基于51单片机的风杯式风速计(附电路仿真图,程序清单)(论文11400字)
摘要：风速计的运用在气象站，船舶上、野外考察中能够起到很大的作用，而在众多的风速计中，风杯式风速计的运用最为广泛。本文介绍了用STC89C52系列单片机设计出来的风杯式风速计，它的硬件组成部分有QS-FS01风速传感器、LCD1602液晶显示器、ADC0804转换器、蜂鸣器等，通过Keil uVision4软件来实现程序的编写，通过Proteus的仿真来确定各个器件之间的连接。它实现的功能是监测风速的大小，通过模数转换器之后将风速的大小和等级显示在液晶显示屏上，并在风速过大时（大于8米每秒时）通过蜂鸣器报警，且红灯在不断地闪烁。

Wind speed measuring instrument based on 51 single chip microcomputer
Abstract:The application of anemometers take a important part in the field of meteorological station, navigation and field study. Among various anemometers, wind-cup anemometer is one of the most widely used. The wind-cup anemometer introduced here is designed by STC89C52 single chip microcomputer. Its hardware parts are QS-FS01 wind speed sensor, LCD1602 liquid crystal display, ADC0804 converter, buzzer and so on. The program were written on the Keil uVision4, and Proteus  simulation was used to confirm the connection between the devices. The function of this anemometer is monitoring the size of the wind speed. The wind speed and grade would be displayed on the liquid crystal display panel through analog-digital converter, and when the wind velocity is too large (more than 8 meters per second), the buzzer would give an alarm, with the red light keeps flashing.
