Abstract:

Aiming at the not timely monitoring for the change of temperature and humidity when grain is in store, which causes the grain in a moldy condition, this paper accomplishes the monitoring system for condition of stored-grain which combines temperature and humidity inspection, and the wireless data transmission by WSN technology. It introduces the system architecture, hardware and software design and monitoring platform design. Proved through practice, this system is featured for high stability, anti-sepsis, mould proof, lightning protection, low-consuming and low-cost, which ensures the storage security effectively.

Key words: sensor node, repeater, Wireless Sensor Network(WSN), monitoring system for condition of stored-grain, monitoring platform

摘要：

针对粮食在存储过程中因未能及时监控温度、湿度等变化，从而导致粮食的发霉变质的问题，设计实现集温度、湿度检测于一体的粮情监控系统，同时利用无线传感器网络实现系统的无线数据传输。介绍系统体系结构、软硬件设计方案和监控平台设计。实践证明，该系统具有稳定性高、防腐防霉防雷击、低功耗低成本等特点，能够有效保障粮食存储安全。
