| 摘 要： | 在桃园应用了基于无线传感器网络的微灌控制系统,通过选取合适功率的太阳能充电板给传感器及路由节点中的锂电池充电,延长节点寿命,实现节点连续稳定工作、采集数据以及传递指令控制水泵和电磁阀的工作状态。节点在不充电情况下,以每天唤醒48次,每次工作20 s的节奏,可以连续工作约70 d,连接太阳能电池板后,可保证充电电量大于耗电电量,有效延长了节点寿命。桃园的园区应用测试表明,转发数据包最多的传感器及路由节点耗电量最大,不充电时单日电压降幅为0.35%,连接太阳能充电板后,电池电压在额定电压附近维持小幅波动。随机改变灌区内被测土壤的湿度,系统可以按照设定的土壤湿度上、下限,自主控制水泵和电磁阀的工作状态,实现按需灌溉。

| Abstract: | The micro irrigation control system based on wireless sensor network is applied in a peach orchard.The solar charger plate with proper power is selected to charge the lithium battery in the sensor and the routing notes in order to prolong the notes life and enable the note to stably collect data, pass command and control the working state of water pump and solenoid valve.When the notes are wakened 48 times a day and work 20 seconds after every wake, they can work for 70 days without charging.After connecting to the solar panel, the power charged rate will be faster than the consumption rate, which ensures longer life of the notes.The test in the peach orchard proves that: the sensors and the notes which pass the most data package consume the most energy;the voltage decline in a single day is 0.35% when they are not charged;the battery voltage only performs a slight volatility around the nominal voltage after connecting to the solar panel.When the humidity of the test soil is randomly changed, the system can automatically control the work state of the water pump and solenoid valve according to the set range of humidity, so can enable an appropriate irrigation. |
