Design and Research of Intelligent Grain Depot Monitoring System Based on Internet of Things
In response to the problems of traditional grain depot environmental monitoring systems such as difficult wiring,difficulty in expansion,and single control method,a smart grain depot monitoring system based on the Internet of Things is designed.The system is divided into upper computer and lower computer.The upper computer is based on Qt and Sqlite3 databases as platforms,and designs display and control interfaces.The lower computer uses CC2530 as the main controller,and combines various sensors and peripheral devices to design coordinators and ter-minal nodes.ZigBee technology is used to achieve wireless communication function in the self-organized network,and real-time communication with the upper computer is achieved through serial port.The system has two control modes to adjust the grain depot environment,namely manual mode and automatic mode.In manual mode,users can indepen-dently control peripheral devices such as fans.In automatic mode,the system can automatically determine whether to turn on peripheral devices based on the set threshold range.The test results show that the system meets the require-ments of grain depot monitoring.It can not only monitor the environmental information of the grain depot in real-time,but also has functions such as early warning and regulating the grain depot environment.
