    摘要:

    針對飛行器內部線(xiàn)纜復雜度高、布線(xiàn)困難的問(wèn)題,提出采用無(wú)線(xiàn)通信模式來(lái)提高傳感器部署的靈活性,減少線(xiàn)纜運輸和安裝成本。為了最大程度地延長(cháng)無(wú)線(xiàn)傳感器節點(diǎn)的使用壽命,對熱電偶無(wú)線(xiàn)傳感器進(jìn)行了節點(diǎn)低功耗優(yōu)化設計。硬件方面,基于DPM機制設計了能量分塊管理模型,核心處理器采用國產(chǎn)低功耗芯片GD32E230C8T6;軟件方面,提出了一種基于星型拓撲結構無(wú)線(xiàn)傳感器網(wǎng)絡(luò )的低功耗策略,并基于此策略給出節點(diǎn)剩余能量數學(xué)表達式。實(shí)驗結果表明,此節點(diǎn)處于停機儲運狀態(tài)下的電流低于1uA,待機模式下的電流低于23mA,證實(shí)了所設計的熱電偶無(wú)線(xiàn)傳感器具有低功耗、穩定的特點(diǎn),能有效延長(cháng)節點(diǎn)壽命。

    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.
