摘要:

针对飞行器内部线缆复杂度高、布线困难的问题，提出采用无线通信模式来提高传感器部署的灵活性，减少线缆运输和安装成本。为了最大程度地延长无线传感器节点的使用寿命，对热电偶无线传感器进行了节点低功耗优化设计。硬件方面，基于DPM机制设计了能量分块管理模型，核心处理器采用国产低功耗芯片GD32E230C8T6；软件方面，提出了一种基于星型拓扑结构无线传感器网络的低功耗策略，并基于此策略给出节点剩余能量数学表达式。实验结果表明，此节点处于停机储运状态下的电流低于1uA，待机模式下的电流低于23mA，证实了所设计的热电偶无线传感器具有低功耗、稳定的特点，能有效延长节点寿命。

Abstract:

Aiming at the problems of high complexity and difficult wiring inside the aircraft, a wireless communication mode is proposed to improve the flexibility of sensor deployment and reduce the cost of cable transportation and installation. In order to maximize the service life of the wireless sensor node, the low-power consumption optimization design of the thermocouple wireless sensor is carried out. In terms of hardware, an energy block management model is designed based on the DPM mechanism, and the core processor selects a domestic low-power chip GD32E230C8T6; in terms of software, a low-power strategy based on a star topology network is proposed, and nodes are given based on this strategy. Mathematical expression for residual energy. The experimental results show that the current of this node is lower than 1uA when it is in shutdown storage and transportation state, and the current in standby mode is lower than 23mA, which proves that the designed thermocouple wireless sensor has the characteristics of low power consumption and stability, and can effectively prolong the life of the node.
