基于三杯式风速传感器的风速监测站设计

Design of Wind Speed Monitoring Unit Based on Three-cup Wind Speed Sensor

鉴于目前可作为计算机监控网络的风速监测仪是非常少见的,论文设计了一种可方便接入分布式监控系统的风速监测站。监测站采用三杯式风速传感器作为风速传感设备,AT89C2051作为MCU,RSM485CHT作为通信接口,通过计数器测量周期得到风速。设计中,给出了监测站结构及组成、风速测量原理及风速传感器接口电路、风速测量程序和数据通信程序。实践表明该设计是切实可行的,具有很强的实用性。

At present the anemometer which could be used as the unit in computer monitoring network is very uncommon. The wind speed monitoring unit which could be conveniently connected to the distributed monitoring system is designed. In the unit, the three-cup wind speed sensor is used, AT89C2051 is used as MCU, wind speed is gained with the counter measuring period, RSM485CHT is used as the communication interface. In the design, the unit corLfiguration, the interface and measurement principle of wind speed sensor, the applications of wind speed measurement and data communication are presented. The application shows that the design is feasible and the unit is very practical.
