摘　　要：介绍了风采集器的设计与实现。随着气象事业的不断发展,气象传感器的数字化、网络化显得越来越重要,而风速、风向是气象要素的重要组成部分。通常,风速与风向传感器输出的是频率脉冲信号和并行GRAY码信号。风速风向采集器主要是将气象传感器输出的信号经调理电路处理后送89S52单片机进行处理,并将处理后的数据通过液晶显示器显示出来。在对频率脉冲信号处理时,采用了特殊的测量方法,其精度得到了提高。在自动化领域,随着分布式控制系统的发展,各种工业控制、智能仪器仪表、数据采集都趋向网络化。RS485是工业应用中的一种支持多节点、远距离的数据传输总线标准,在数据通信中,采用了RS485传输标准。This paper introduces the software design of the wind speed and direction collector With the increasing development of meteorology,the digitalization and the networking of meteorological sensor become more and more important,and the wind speed and direction are the important component of meteorological measuring.Usually,the output of wind speed and direction transducer is the frequency pulse signal and GRAY code signal.The main function of wind speed and direction collector is to deal with the meteorological sensor output signal by the conditioning circuit and transform it to the 89S52 MCU for further processing.The processed data are displayed by the LCD.This paper uses a special measure technique when processing frequency pulse signal so as to enhance the precision.In automation field,with the development of distributed control system,various industrial control,intellectual instrument and apparatus and data acquisition tend to the form of network.RS485 is a data transmission bus standard that supports the multi-pitch points and the long-distance data transmission in the industrial application.Therefore RS485 transmission standard is used in data communication.
