摘　　要：针对两种基于对称热电偶结构和基于晶体管的圆形加热条结构的二维集成风速风向微传感器及其风向测量的问题,设计了采用微控制器进行在线控制和利用软件算法实现风速风向测量的传感器系统。系统集微传感器结构、控制与测量电路于一体,显著提高了二维风速风向传感器的在线控制和测量能力及其系统兼容性,并且便于系统扩展功能。测试结果表明,风速计设计满足实际风速和风向的测量要求。The control and measurement circuits of an anemometer are complex and difficult to design, especially the wind direction measurement. An on-line control and measurement system for both wind speed and direction using the micro-controller is presented to solve this problem. This system aims at the two kinds of anemometer designed by our lab. One has a symmetrical thermopiles structure, and the other has a circular heater structure. The system integrates the sensor structure, control and measurement circuits. It markedly improves the on-line control and measurement ability and the compatibility. The test result shows that the system satisfies the measure requirement.
