摘要
基于STM32和STC89C52单片机设计一种分布式无线自动浇灌系统,用以实现农业灌溉的智能化,系统包括一个主机和多个从机,土壤温湿度检测模块和电磁阀浇灌模块与从机相连,完成数据的采集、发送及处理功能,以继电器控制电磁阀工作,通过开关水泵实现自动浇灌,从机个数可根据测量点的需求进行扩展。显示模块和报警模块与主机相连,完成数据的接收、处理、显示及报警功能。主从之间采用NRF905模块进行无线通信,构成'一对多'的通信网络。系统有效地解决传统灌溉体系中低效率的问题,试验结果表明,该浇灌系统无线传输数据可达145 m,实现通过设置不同区域内不同农作物需水量后,自动进行科学灌溉。
It is designed that a distributed wireless automatic irrigation system based on STM32 MCU and STC89 C52 MCU to realize the intelligence of agricultural irrigation.This system includes a host computer and multiple slave computers.The soil moisture and temperature detection module and the electromagnetic valve irrigation module are connected with the slave computer to complete the data acquisition,transmission and processing functions.The system controls the solenoid valve by relay,and automatically pumps through the switch pump.The number of slave machines in the system can be expanded according to the demand of measurement points.The display module and the alarm module are connected with the host computer for receiving,processing,displaying and alarming the data.The NRF905 module is used for wireless communication between host and slave,forming a one to many communication networks.The system can effectively solve the problem of low efficiency in the traditional irrigation system.The experimental results show that the wireless transmission data of the irrigation system can reach 145 m.The system realizes automatic scientific irrigation by setting different crop water demand in different regions.
