基于ZigBee技术的无线传感器网络具有低功耗、低成本、高灵活性和自组网的特点,将其应用于飞机的状态监测,可以有效地解决传统状态监测技术中功耗大、成本高和不易维护的问题;鉴于这一应用要求,我们采用TI公司的CC2531芯片,在ZigBee协议栈的基础上设计了可以监测振动、应力应变等状态参数的无线传感器网络节点,并在模拟的环境中进行了试验,节点传输距离提高到了40m,证实了该方案的可行性。
The wireless sensor network based on ZigBee technology has the characteristics of low power consumption, low cost, high flexibility and ad hoc network. It is applied to the condition monitoring of aircraft, which can effectively solve the problems of high power consumption and high cost in traditional condition monitoring technology In view of this application requirement, we use TI’s CC2531 chip, based on the ZigBee protocol stack designed to monitor vibration, stress and strain and other state parameters of the wireless sensor network node, and in a simulated environment The test, the node transmission distance increased to 40m, confirmed the feasibility of the program.
