摘要：

为提高温室环境监测的精准性，降低环境感知成本，设计了多点环境监测系统。针对秋冬季温室温度管理难度大导致的番茄病害率增加等现象，对山东省番茄温室内的温度进行持续监测，依据实测数据选用高斯函数对温室温度的日变化曲线进行最小二乘多峰拟合，将离散的数据点转化为连续的高斯函数，通过积分比较得到番茄各生长周期的最佳监测位置。结果表明，以高斯函数为目标对温室温度进行多峰拟合分析，效果较显著，最小决定系数为0.919；番茄苗期与开花坐果期，监测点N₁₅、N₁₀与温室平均温度之间温度曲线积分面积的绝对差最小，因此该生长时期的最佳监测点为N₁₅和N₁₀；番茄结果期，N₁₀和N₃监测点所在位置最接近温室整体平均变化水平，为该周期的最佳监测位置。综上，在番茄不同生长周期中，温室中部监测点N₁₀更能代表温室整体水平，该方法为温室环境精准监测奠定了基础。

Abstract:

In order to improve the accuracy of greenhouse environmental monitoring and reduce the cost of environmental perception， this study designed a multi-point environmental monitoring system. Aiming at the difficulty of temperature management the increase of tomato disease rate in autumn and winter， the temperature in tomato greenhouse in Shandong province was continuously monitored. Based on the measured data， gaussian function was used to fit the daily variation curve of greenhouse temperature by least square multi-peak method， and the discrete data points were converted into continuous Gaussian function， and the optimal monitoring position of tomato in each growth cycle was obtained by integral calculation and comparison. The results showed that multi-peak fitting analysis of greenhouse temperature with gaussian function as the target had significant effect， and the lowest goodness of fit was 0.919； the absolute difference of integral area of temperature curve between monitoring points N₁₅ and N₁₀ and the greenhouse average temperature was the smallest in seedling and flowering and fruit-setting periods of tomato， so the best monitoring points at this growth period were N₁₅ and N₁₀； the locations of N₁₀and N₃monitoring points at tomato fruit period were closest to the average change level of greenhouse as a whole， which were the best monitoring position at this period. In conclusion， in different growth period of tomato， the monitoring point N₁₀ in the middle of the greenhouse could better represent the overall level of the greenhouse. This method laid a foundation for the accurate monitoring of the greenhouse environment.
