改善能源结构,发展新的可再生能源,减轻对环境的污染,提高电能质量,已成为世界能源工业关注的一个热点。风能由于其突出的优点在可再生能源开发利用中倍受世界各国普遍重视,风力发电技术也成为各国学者竞相研究的热点。

本文在了解传感器工作原理以及单片机相关知识的前提下,设计了一种的风电厂气象数据测量系统。该系统采用单片机技术, 由风速风向传感器,压力传感器及温湿度传感器采集数据,单片机负责控制系统各部分器件的工作并对数字信号进行处理。然后将气象数据经无线通信模块发送给上位机软件,并由上位机显示出来。该系统以AT89S52作为微处理器,具有强大的数据计算处理能力及控制能力,此外由于其内部集成了多种硬件电路接口,有效地降低了成本,减小了装置体积。

系统硬件设计是本课题的重点研究内容,系统分为四个模块,分别为电源模块、数据采集模块、信号处理模块、以及与上位机通信模块。硬件系统主要完成风速,风向,压力,温度,湿度数据的采集、处理、原理图设计。软件部分也是本论文的主要工作所在,软件主要完成单片机工作、以及上位机软件的控制。

关键词:单片机,风压,风速,数据采集,数据处理

mprove energy structure, the development of new renewable energy, reduce

environmental pollution and improve power quality, has become a hot topic of concern

to the energy industry. Wind due to its outstanding advantages in the development and

utilization of renewable energy much attention to countries in the world, wind power

technology has become a hot research scholars from variouscountries compete. To

understand the working principle of this sensor and microcontroller-related knowledge

of the premise, introduces a new wind farm meteorological data measurement system.

The system uses microcontroller technology, the wind speed and direction sensor and

temperature and humidity sensor to collect data, extract the sensor analog signal

amplification and analog to digital converter, microcontroller control system is

responsible for the work of the various parts of the device and digital signal processing.

Meteorological data and then sent via wireless communication module to the host

computer software by the host computer is displayed. AT89S52 as the system

microprocessor, with powerful data processing power and control, also because of its

internal integration of a variety of hardware interfaces, effectively reducing the cost and

reduce the device volume. System hardware design is the focus of this research project,

the system is divided into four modules, namely, power modules, data acquisition

module, signal processing modules, and with the host computer communication module.

Complete hardware system is mainly wind speed, wind direction, temperature, humidity,

data acquisition, processing, Schematic, Software part is also where the main work of

this thesis, software mainly to complete single chip work, analog components, as well as

PC software control. Micro-controller software design while a modular design to

enhance the portability of the software system, readability and stability.

Keywords: microcontroller, air pressure, wind speed, data collection, data processing,
