植物叶片厚度和果径精密测量传感器的设计

Design of precise measuring sensor of thickness of plant lesves and diameter of plant fruit

通常的灌溉系统是以空气的温度、湿度以及土壤的湿度作为控制参数,属于开环控制。针对这一问题,提出了以植物的器官(叶片、茎杆、果实)的几何参数为控制参数的智能节水灌溉控制系统,属于闭环控制,提高了准确度。主要介绍了对植物叶片和果实进行控制的传感器的设计与制作及误差分析,对传感器的参数进行了优化配置,研究结果对传感器的实用化具有指导意义。

The usual system of irrigation depends on the temperature and humidity of the atmosphere and the humidity of the soil as the control parameter,it is non-closed loop control system.Aiming at this problem,the intelligent saving-water irrigation control system which looks on the geometry parameter of the plant's organic(leaves,stalk,fruit)as the control parameter is presented,it is closed loop control system,then it can improve the accuracy.Here the design and facture of the sensor which controls the leaves and fruits of the plant are introduced,moreover the error is analyzed and the collocation of the parameter of the sensor is optimized,the study result has the significance to guide the practicality of the sensor.
