摘要
为解决作物浇灌时不能合理掌握浇灌量的问题,提出一种渐进式定点精准远程控制浇灌装置,用以实现精准浇灌、远程控制和警报等功能。硬件实现方面主要包含金属箱体、基于CC2530芯片的中央控制器、湿度采集设备、浇灌设备、无线通讯设备和警报设备;在数据采集和处理阶段,首先通过湿度传感器采集数据,模拟土壤渗透速率表,动态进行浇水量调整,中间预留空隙时间以等待水分下渗,随后按更新的湿度数据自动调整补水量,以此保证在不积水的条件下调整到适宜湿度,实现精准灌溉;通过进行对比试验,得到土壤的适宜湿度范围,明确分段式浇灌方法对植物整体生长及资源消耗的明显效果。结果表明:该浇灌方法在试验中表现相对稳定,对比人工浇水作业,实用性有所提升,用水量显著降低,该分段式浇水模式有效解决了积水等问题。该浇灌系统有良好的自动化功能,能够保证浇水作业的效果,为实现大规模灌溉作业奠定了基础。
To solve the problem that the amount of irrigation can not be controlled reasonably during crop irrigation, a progressive fixed-point precision remote control irrigation device is proposed to realize the functions of precision irrigation, remote control and alarm. Hardware implementation mainly includes metal box, central controller based on CC2530 chip, humidity acquisition equipment, irrigation equipment, wireless communication equipment, and alarm equipment;In the data acquisition and processing stage, firstly, through collecting data with humidity sensor and simulating soil penetration rate table, dynamic watering volume is adjusted, space time is reserved in the middle to wait for water infiltration, and then according to the updated humidity data, the amount of make-up water is automatically adjusted, so as to ensure that appropriate humidit can be adjusted to under the condition of no ponding to achieve accurate irrigation. Through the comparision experiments, the suitable humidity range of soil is obtained, and the apparent effects of segmented irrigation method on overall growth and resource consumption of plants are clarified. It can be concluded that the irrigation method shows a relative stability in the test, compared with the artificial watering operation, the practicality is improved and water consumption is decreased, and the segmented watering method effectively solves the problem of ponding. The irrigation system has good automation function, which can ensure the effect of watering operation, and lay the foundation for realizing large-scale irrigation operation.
