【摘要】：為提高水資源利用率和灌溉智能化管理的需要,設(shè)計了基于CC2530的荔枝園智能灌溉系統(tǒng)。該系統(tǒng)的傳感器節(jié)點負(fù)責(zé)采集荔枝園數(shù)據(jù),并通過無線傳感器網(wǎng)絡(luò)將數(shù)據(jù)發(fā)給協(xié)調(diào)器節(jié)點,協(xié)調(diào)器節(jié)點將數(shù)據(jù)傳送給上位機(jī),通過分析土壤水分?jǐn)?shù)據(jù),結(jié)合系統(tǒng)預(yù)設(shè)閥值發(fā)送命令給電磁閥控制節(jié)點控制雙穩(wěn)態(tài)脈沖電磁閥,實現(xiàn)設(shè)備的遠(yuǎn)程控制和智能化灌溉。節(jié)點在空曠地帶的有效通信距離達(dá)826m,在荔枝園中有效通信距離達(dá)122m。結(jié)果表明,網(wǎng)絡(luò)平均丟包率為0.75%,該系統(tǒng)運(yùn)行穩(wěn)定,能較好地滿足荔枝園灌溉遠(yuǎn)程監(jiān)控的應(yīng)用需求。
[Abstract]:An intelligent irrigation system for litchi orchard based on CC2530 was designed in order to improve the utilization rate of water resources and the intelligent management of irrigation. The sensor node of the system is responsible for collecting the data of litchi orchard, and sends the data to the coordinator node through the wireless sensor network, and the coordinator node transmits the data to the host computer, and analyzes the soil moisture data. Combined with the preset threshold of the system to send commands to the solenoid valve control node to control the bistable pulse solenoid valve to realize the remote control of the equipment and intelligent irrigation. The effective communication distance between the nodes in the open area and in the litchi garden is 826m and 122mrespectively. The results show that the average packet loss rate of the network is 0.75. The system is stable and can meet the requirements of remote monitoring and control of litchi orchard irrigation.
