摘　　要：为了更好地研究土壤含水率的变化情况,设计制作了一套由ATmega128单片机、μC/OS-Ⅱ操作系统、BD-Ⅰ型土壤水分传感器、RS-485以及RS-232总线式数据传输等组成的土壤水分监测系统,实现了土壤含水率的实时监测。相对于传统单片机监测系统,本系统由于软件上加入了μC/OS-Ⅱ操作系统,实现了多任务并行处理功能,使系统在稳定性、快速性等方面有了明显改善。This paper describes a monitoring system of real-time soil water content from both perspectives of hardware and software.The system consists of an ATmega128 microcontroller with embedded μC/OS-Ⅱ operating system,BD-Ⅰ type soil moisture sensors,RS-485 and RS-232 bus-based data transmission technologies.Compared with traditional microcontroller monitoring systems,the reliability and processing ability of the system are improved greatly by adding the μC/OS-Ⅱ operating system,which brings realtime multi-task processing capabilities.The system has significances in improving water utility efficiency and precise irrigation control in urban greening as well as agricultural and forestry production.
