摘 要: 该系统采用三层结构,使用CC2420射频芯片、ATmega128L单片机、SHT11数字温湿度传感器组成下位机、分机,上位机使用PC机,该系统能实现实时检测粮仓温湿度,并通过无线方式传送数据,能实现粮仓管理、超限报警、查询打印等各种管理功能,与传统的粮情检测系统相比,具有易于布设、维护、扩展等优点。 The system uses three - tier structure. It composes the lower computer and the point computer using the CC2420 RF chip,ATmega1128L SCM, SHT11 digital temperature and humidity sen- sors. The top computer uses PC. The system can measure granary temperature and humidity on real time and transmit data by wireless communication and achieve granary management, over- limit a- larm, query and print, and other management functions. Compared with traditional grain inspection system, this system is easy to layout, maintenance, expansion and so on.
