摘　　要：为使作物始终处于最佳的生长状态,针对作物生长各个阶段对CO2浓度的不同需求,结合温室大棚自身的特点,设计了一套以Cortex-M3内核的STM32芯片为核心,采用GPRS无线通信技术的日光温室CO2浓度自动控制系统,实现了温室内CO2浓度的自动监测与调控。试验结果表明,该系统运行可靠、使用方便,具有较强的可扩展性,应用前景良好。Aimed at the different demand for CO2 concentration of plants during the growth, a set of automatic CO2 control system was designed to offer the sustainable favorite growth conditions for crops cultivated in greenhouse. Based on the characteristics of greenhouses, the designed system adopted STM32 of Cortex-M3 kernel as the core, and applied GPRS wireless communication technology to realize the automatic monitoring and controlling of CO2 concentration in greenhouses. The test results showed that the system was reliable and easy to use. Besides, this system possessed good scalability, and thus had good application prospects.
