风洞无线智能传感器网络及无线测量技术研究

风洞试验现场，特别是大型连续式风洞试验现场的电磁环境非常恶劣，而风洞实验中的测量信号又是毫伏级的微弱信号，采用传统测量方式难以克服恶劣的电磁环境对测量系统的干扰。对于运动物体或无法布线的试验环境进行参数测量时，传统测量方式完全不起作用。针对上述问题，笔者对风洞无线智能传感器网络和无线测量技术进行了研究，采用ZIGBEE技术实现了风洞无线智能传感器网络和基于该网络的无线测量模块。极大地增强了测量系统的抗干扰能力，提高了风洞试验的精细化程度，降低了测量系统的经济成本。

The research of intelligent wireless sensor network （WSN） and wireless measurement technology for wind tunnel

Electromagnetic environment is very adverse at experiments in wind tunnel, especially in largescale continuous wind tunnel, but measurement signal is very weak. It is difficult to avoid disturbing measurement system under the bad electromagnetic environment by using traditional measurement methods. One even can＇t measure parameters by traditional measurement methods when the wiring installation is complex or object is moving. In this paper, the author studied intelligent Wireless Sensor Network and wireless measurement technology of wind tunnel, and realized construction of intelligent Wireless Sensor Network of wind tunnel based on ZIGBEE, completed the design of wireless measuring module based on the network, improved systematic anti-interference ability, improved experimental preciseness and reduced the cost.
