    摘要:

    為了降低現(xiàn)有設施環(huán)境監(jiān)測系統(tǒng)中傳感節(jié)點的能耗,延長無線傳感網(wǎng)絡的生存周期,提出了節(jié)點動態(tài)組包主動傳輸和多種環(huán)境變量加權(quán)控制傳輸2種低功耗機制,減少了大量重復冗余數(shù)據(jù)的傳輸,并實現(xiàn)了基于Zigbee的設施花卉環(huán)境監(jiān)測及其低功耗傳輸系統(tǒng)。提出設施花卉環(huán)境下的多變量模糊控制方法,解決了環(huán)境變量之間耦合問題,促使溫室快速達到花卉適宜環(huán)境并保持平衡,實現(xiàn)了對設施花卉環(huán)境的綜合控制。節(jié)點以CC2430芯片為核心,并根據(jù)影響花卉生長的環(huán)境參數(shù),同時裝載SHT10型溫濕度、BH1750FVI型光照以及COZIR-ambient型二氧化碳傳感器,因此節(jié)點可同時采集傳輸多種環(huán)境參數(shù),降低了硬件成本。在南京農(nóng)業(yè)大學園藝試驗基地進行組網(wǎng)測試,結(jié)果表明,系統(tǒng)比傳統(tǒng)周期傳輸節(jié)點(周期1min)減少能耗85.97%,測量精度在98.5%以上,網(wǎng)絡平均丟包率為0.84%,滿足了對設施花卉環(huán)境的有效監(jiān)測及低功耗傳輸?shù)囊蟆*?/p>

    Abstract:

    Two low power consumption mechanism, named active transmission of node dynamical package and weighted control transmission of environmental variables, were proposed. A large number of duplicate and redundant data in transmission was reduced. The facilities flower environmental monitoring and its low-power transmission system based on Zigbee was achieved. The multivariable fuzzy control method in facilities flower environment was proposed, which solved the coupling problem in environmental variables and helped greenhouse to reach the comfortable environment of flowers rapidly and keep balance. CC2430 chip was used as the core of the node. SHT10 temperature and humidity sensor, BH1750FVI light sensor, and COZIR carbon dioxide sensor were also used in accordance with the environmental parameters which would affect the growth of flowers, so the nodes could collect and transmit a variety of environmental parameters at the same time, which reduced the cost of hardware. Networking test was carried out in Nanjing Agricultural University. Test results showed that the proposed system reduced energy consumption by 85.97% compared with traditional cycle node (cycle was 1 min), and measurement accuracy was more than 98.5%. The average loss rate of network packet was 0.84%. 
