    摘要:

    構(gòu)建了一套增氧系統(tǒng)，采用耕水機(jī)和微孔曝氣增氧機(jī)混合增氧的模式，白天通過定時控制以耕水機(jī)工作為主，晚上或陰雨天缺氧時以微孔曝氣增氧為主。在環(huán)境參數(shù)不斷變化的情況下，為了保持溶解氧的穩(wěn)定，控制方法采用誤差反傳的模糊神經(jīng)網(wǎng)絡(luò)控制。試驗表明，在相同條件下采用混合式增氧控制較傳統(tǒng)的葉輪式增氧可節(jié)約電能40.6%，提高產(chǎn)量31.9%,最終利潤提高136.1%。水質(zhì)參數(shù)測量采用Zigbee通信，通信協(xié)議采用優(yōu)化的低能量自適應(yīng)分層協(xié)議，并根據(jù)水體溶解氧測量的實際要求，設(shè)置參數(shù)測量的軟、硬閾值以減少節(jié)點(diǎn)數(shù)據(jù)發(fā)送的次數(shù)，達(dá)到節(jié)能和供電電池剩余能量均衡的目的，試驗表明優(yōu)化后的無線傳感網(wǎng)絡(luò)壽命延長了58%。

    Abstract:

    The hybrid applications of biofan and micro-porous aerator were adopted. Biofan was mainly used in daytime and micro-porous aerator was mainly used usually at night or in rainy days. With the changing environmental parameters, a fuzzy neural network based on reversed error propagation was applied to maintain the stability of dissolved oxygen. Tests showed that 40.6% energy was saved. The output was increased by 31.9% and the final margin was increased by 136.1%. Zigbee network was applied in the measurement of water quality parameters. The optimized LEACH communication protocol was used to achieve the purpose of node energy conservation and loss balance. According to the actual measurement of dissolved oxygen requirements, soft and hard threshold parameters were set to reduce sending times of mode data. Tests showed that the lifetime of optimized wireless sensor network was extended by 58%.
