风能作为一种新兴的可再生能源,其发展有着重要的战略意义。风电场是人们利用风能最直接的场所,但是风场的建设却是一个复杂的过程,尤其是在风场选址的时期,风场选址离不开气象数据,需要对风场的气象参数实时监测,而风速是风场建设时的核心数据,为了能实时准确的获得风速信息,本文设计了一个风速测量系统,系统硬件以C8051F020单片机为核心,采用EC9-1三杯式风速传感器采集风速信息,利用单片机的两个通用定时计数器, 对风速脉冲进行定时和计数, 通过计算单位时间内的脉冲数计算出风速。其次使用RS485 通信协议,将不同测量平台的信息汇总,然后通过GPRS/GSM模块将风速数据送往上位机进行处理和保存。

Abstract
Wind energy as a new renewable energy has the important strategic significance in its development. Wind farm is the most convenient site where people can use wind energy directly. while its construction is a complex process, especially in the field of the wind farm site selection which can not do without meteorological data, the detection for the meteorological parameters in a real-time is necessary. In order to get the accurate information in a real time as the wind speed is the most needed data in the construction , the paper today show a design of a wind speed meter, with a C8051F020 MCU system hardware core and a EC9-1 cups-style wind sensor as to collect wind speed information . using two general-purpose microcontroller timing counter, the timing and speed pulse count ,you can calculate the number of pulses per unit time to achieve the wind speed. Second, the design of RS485 communication protocol is to sum the different platform of information in measurement , and then GPRS / GSM module will sent the wind data to the host computer for processing and preservation.
