　　基于嵌入式系统与总线技术设计了轮灌控制系统。轮灌总控制器和分控制器用 RS-485总线连接。总控制器由STM32F103VET6微处理器，LCD、按键、MAX3075总线驱动器、MC551 GPRS 通讯模块组成；分控制器由STM8L151K4微控制器、L9110S电磁阀驱动芯片、模式配置跳线和 EC-5土壤水分传感器接口组成。基于对象总控制器嵌入式完成人机界面设计，并据芯片出厂序列号为分控制器分配通信地址，采用低功耗设计降低系统整体功耗。人机界面、远程服监控与轮灌控制试验表明：轮灌控制系统人机界面响应迟滞时间小于50ms， GPRS通信误码率低于10％。灌溉试验表明，轮灌控制器能够满足定时、分区灌溉的要求。

This paper described an automatic rotational irrigation system for orchard irrigation application based on em -bedded real time system and bus expansion technology .This system contains a master controller and several slave valve monitor connected via standard RS-485 bus .On hardware , the master controller contained a STM 32 F103 VET6 micro-controller, LCD module, user keys, MAX3075 bus driver and MC55i GPRS module.Slave valve monitor contained STM8 L151 K4 microcontroller , L9110 S valve driver and EC-5 soil moisture interface .This paper also introduced an ob-ject-oriented method for designing LCD based real time system and user interface and slave valve monitor address alloca -tion strategy based on STM 32 unique ID .Low power design method was suggested to reduce the whole system power con-sumption .The test in the orchard show that the rotation irrigation system show that , the response time for user interface was less than 100ms, GPRS packet loss rate was lower than 10%, and satisfied the requirement of orchard rotation irri-gation.
