摘　　要：粮食在仓储过程中会受到生物场和非生物场等诸多方面影响,从而导致易出现发热、霉变、结露以及虫害等现象,迫切需要研发便捷、快速、多功能和高精度的现场检测工具。多功能储粮安全现场快速检测分析仪针对实际储粮管理的需求,在多点高精度检测温度、湿度和CO_(2)浓度的基础上,以模型和算法推算储粮水分、水分活度、绝对湿度、积温、积湿、J/Q值和绝对水势,对推算结果进行图形化表达,辅助判定安全、结露、发热、霉变等储粮状态、选择机械通风作业参数,并进行智能控制。初步应用结果表明,该仪器对粮仓管理能够提供有效技术支撑,具有良好的应用前景。The grain storage process could be affected by many aspects such as biological field and non biological field, which will lead to the phenomenon of heating, mildew, dewing and pest damage in the grain storage process. It is urgent to develop convenient, fast, multi-functional and high-precision on-site detection tools. According to the requirements of actual grain storage management, the multi-functional grain storage safety on-site rapid detection analyzer could calculate the stored grain moisture, water activity, absolute humidity, accumulated temperature, accumulated humidity, J/Q value and absolute water potential with models and algorithms on the basis of multi-point high-precision detection of temperature, humidity and CO2concentration, and could graphically expresse the calculated results to assist in the determination of stored grain conditions such as safety, condensation, heat, mildew, etc, which will have mechanical ventilation operation parameter selection and intelligent control. The preliminary application of the instrument shows that it can provide effective technical support for granary management and has a good application prospect.
