基于PLC的寒地水稻水肥一体化灌溉系统设计

Irrigating System Design of Integration of Water and Fertilizer of Rice in the Cold Field Based on PLC

为了加快垦区水稻水肥一体化技术的应用发展,提高水稻生产中自动化、信息化水平。根据水稻在不同生长期的需水、需肥量要求,设计了以PLC为控制核心,通过无线通信方式,实现对水稻农田的土壤水分、水位、设备工作状态等数据进行采集分析的系统,可实现远程或现场控制执行设备自动完成农田灌溉和施肥控制,提高灌溉和施肥的均匀性、及时性和简便性。利用上位机管理软件将各项数据统一存入数据库,供管理者和生产者进行数据分析和对比,为垦区水稻的现代化生产和水稻产品质量安全管理提供可靠的保障。

In order to apply to speed up the development of water and fertilizer ’ s integrated management and increase in rice production automation and informatization level , according to the rice in water , different requirements in growth pe-riod of fertilizer, the paper Completed a method to acquire and analysis the data of rice farmland soil moisture , water level, equipment working condition and so on by designing with PLC as control core and throughing wireless communica -tion.The system realizes automatic irrigation and fertilization control equipment on remote or on -site areas.It improves the uniformity of the timeliness and convenience for irrigation and fertilization .The manager and producer can make data analysis and comparison from the data stored in the database by using the unified management software .This system can provide a reliable guarantee for the rice production , quality and safety management on the reclamation area .
