Design and implementation of embedded monitoring system for grain storage

Meeting the requirement and development of large granaries, an embedded environmental monitoring system for grain storage based on ARM technology is designed in this paper. The overall structure of the proposed monitoring device consists of two components, one is the host computer located in control room for information processing and prediction of grain situation, the other is the lower computer terminal in the granary with grain data acquisition, signal processing and communication functions. They transmit data to each other over industrial Ethernet or GPRS networks. On this basis, the implementation methods of data monitoring terminal for grain situation based on S3C2410 microprocessor are studied in detail. The human machine interface of the terminal is developed by Qt/Embedded. Finally, the feasibility and reliability of the system has been proved by the laboratory test.
