基于无线传感网络与模糊控制的精细灌溉系统设计

基于在农田灌溉中,由于灌溉面积较大、数据实时传输较难,以及数据过多等特点,设计了一种建立在无线传感网络与模糊控制基础上的农田自动灌溉节水系统.该系统可以综合运用无线传感器的数据处理与无线数据的传输功能,对农田自动化灌溉做到实时有效的监控与管理,从根本上提升整个系统的自动化程度.系统主要采用的结构组图是星型式的,其运行的机理就是在每一个检测区域都装有ZigBee网络节点,实时的将获取的检测数据传入测控系统,在数据上实现统一的传输与处理;每一个区域的无线传感器都实时持续地处理区域内土壤湿度的变化,及时将数据向接收端传输,接收端再根据接收到的数据进行存储、处理与显示,对自动化灌溉系统进行控制,做到有效的节水与灌溉.根据已有的数据表明,该系统在运行过程中是比较稳定的,数据的传输也比较稳定,且在传输过程中很少发生数据的丢失,同时具有可应用范围广、可普及性强等特点,是进行自动化节水的有效手段.

Wireless sensor network and fuzzy control design of precision irrigation system based on

In farmland irrigation, for the irrigation area is large, real-time transmission of data is more difficult. With too much data, this paper designs a kind of based on wireless sensor network and fuzzy control based on the farmland automatic irrigation system. The biggest advantage of the system lies in the fact that it can transmit data processing and wireless data using wireless sensor of the integrated monitoring and management, achieve real-time and effective management and control of farmland irrigation automation, which can improve the automation degree of the whole system. This system mainly adopts the star-typed structure of photos, and its operation mechanism in each detection area are equipped with ZigBee network node, real-time detection of data acquisition and control system to realize the incoming, transmission and processing of unity in the data;The change of wireless sensor in each area are processed with real-time continuous treatment of regional soil moisture, timely data transmission to the receiving end, and to the receiving terminal for storage, processing and display, to control automatic irrigation system, which achieves the effective water and irrigation. The results show that, the system is stable in operation process, the data transmission is relatively stable, data loss hardly occurs during the transmission and it enjoys the characteristics of wide application, strong popularity, which is an effective means of saving automation.
